Double congratulations to Bella, who passed her MSc exam AND had a first paper accepted, all in the same week (and all while she was en route driving between the Rock and Ontario). Way to go Bella! Bella will be starting a PhD at Concordia in January, working with Carly Ziter in the urban landscape ecology lab.

Bella’s paper is out of the TERG project and will be in press soon:

Richmond IC, SJ Leroux, E Vander Wal, T Heckford, M Rizzuto, J Balluffi-Fry, J Kenna, YF Wiersma. Accepted. Temporal variation and its drivers in the elemental traits of four boreal plant species. Journal of Plant Ecology.

November 2020

The big event in the lab this month was Bella’s exit seminar – delivered online, which made it a little less celebratory… however, the online nature meant her mom could attend, as well as some former lab mates, which was cool!

Congratulations to lab alumni Patrick on the acceptance of the third and final chapter from his MSc thesis!

September 2020

Well it’s another academic new year, and it will be a bit of a different one.

Our university is doing undergrad courses online and access to campus and labs is still limited. I’m on sabbatical, so was planning to work from home most of the time (I hadn’t planned to travel anyways).

We’re welcoming three new members to the LESA Lab – check out their profiles on the “people” page. We’ll be scattered in different physical locations for the next while, but we’ll still be meeting and working actively on research, which we will keep you

August 2020

Congratulations to two lab alumna – Rachel and Tegan – who each had a chapter of their respective MSc theses accepted for publication this month. References below.

Padgett TA, YF Wiersma. Accepted. Importance of boreal forested swamps for arboreal macrolichen communities. Canadian Journal of Forest Research.

Wigle RD, YF Wiersma, A Arsenault, RT McMullin. In press. Drivers of arboreal lichen community structure and diversity across scales. Botany.

On top of that, two papers from the TERG team recently got accepted – details will be posted here later.

Despite the challenges of COVID, folks are still hard at work. Alumnus Patrick is working on revisions to the last chapter of his MSc,and our our guest visitor from a few years ago, Jennifer D is also about to re-submit a paper.

And congrats to lab alumna Tegan, who landed a job in BC to develop a Land Stewardship Guardian program with the Stswecem’c-Xgat’tem First Nation!

June 2020

I facilitated a few online discussion in April about online teaching, which we have collectively developed into an online blog post. You can read it here.

Despite that we are all working from home during the global COVID-19 pandemic, things are still happening at the LESA Lab.

First, I have to catch up on reporting of a lab member’s recent achievement that I forgot to post in the last few months. Bella recently was awarded the Canadian Institute of Geomatics -NL chapter Student Scholarship. Because of COVID we don’t have a photo of her receiving her certificate (and cheque!). Congratulations Bella!

Second, I mentioned in the May monthly news that lab alumna Tegan had a paper out based on work she did at Terra Nova National Park following completion of her MSc. I neglected to include the citation, so here it is.

Pagett T, A Aresenault, RT McMullin. 2020. Chaenotheca brachypoda and Sclerophora peronella, Two calicioid lichens new to Newfoundland and Labrador from Terra Nova National Park. Evansia, 37(2):61-70

Now on to June updates:

In provincial conservation, some exciting news: the Natural Areas System Plan is finally out. Residents of the province are welcome to comment on the plan. Read more here.

Patrick has a second chapter from his thesis accepted for publication! Congratulations!

Lauriault P, YF Wiersma. In press. Identifying critical habitat for boreal felt lichen (Erioderma pedicellatum) in Newfoundland, Canada. The Bryologist.

Bella has submitted her first chapter for peer-review – an important milestone! Way to go!

And congrats to lab alumna Tegan, who landed a job in BC to develop a Land Stewardship Guardian program with the Stswecem’c-Xgat’tem First Nation!

May 2020

I facilitated a few online discussion in April about online teaching, which we have collectively developed into an online blog post. You can read it here.

Despite that we are all working from home during the global COVID-19 pandemic, things are still happening at the LESA Lab. Here are some highlights from recent weeks:

  • Congratulations to Patrick on passing his MSc Thesis examination! He’s now off to start a PhD at Waterloo with Andrew Trant.
  • Lab almuna Tegan received positive reviews on a recent journal submission (chapter 2 of her thesis) as well as an acceptance of a paper not related to her thesis (completed as part of a contract she got right after finishing her MSc)
  • Travis has submitted a couple of papers from his thesis.
  • Travis and Bella have prepared exciting presentations for the IALE Virtual Meeting

Also, the IALE-North America Virtual meeting happens this month! If you are curious what a virtual meeting will look like, check out this video tour of our “Virtual Venue“. As well you can watch our “Kick off Webinar“. All other conference events are behind a paywall (you can register as late as May 10).

And a final note from a lab alumnus – Shad Mahlum, who successfully defended his PhD in Norway this week. He had to defend remotely, which called for an specific dress code! Congratulations Dr. Mahlum! Shad finished his MSc in the LESA lab back in 2013.


April 2020

Well, things have certainly changed since the last update, and we’re 2 weeks into April and I’m just updating the website.

The term finished up online, owing to the COVID-19 pandemic. I’m glad to report all my grad students are safe and well. Fortunately they are all in write-up stage, and didn’t have field work planned. Field work for this coming season looks doubtful… I’ll be brainstorming some data-driven and writing projects for students for the coming year.

In my last post I announced that the IALE-North America meeting was up. Five days later, we made the decision to move from an in-person meeting in Toronto in May to a virtual meeting. It’s still going to be great; if you had a planned conference get cancelled, I encourage you to “attend” virtually to experience some great presentations (unfortunately we can’t accept new abstracts)!

March 2020

March has come in with more snow (!), which has made heading to our study site to check our hare collars a challenge. Nonetheless, folks are plugging away at projects. Patrick got helpful comments on two manuscript revisions, and Tegan and Travis have each submitted thesis chapters to journals.

This month brings the Science Atlantic meeting. Honours student Gabby is presenting there, and I will be one of the keynote speakers. It should be fun!

And, in other conference news, the schedule for the IALE-North America meetingis up. It was a bit of work this past month as Program Co-chair to finalize this, but we have a schedule. Check it out and consider attending!

February 2020

Well, January is over. What a month. #snowmageddon2020 was a lot of fun. It pooched Bella’s trip to Nova Scotia for the QAtCan STEM Colloquium, though she was able to present her work remotely.

Kudos to two alumni! Tegan submitted a second paper from her MSc to a journal for peer-review this month, and Rachel (with help from committee members) also has a thesis chapter submitted to a peer-reviewed journal.

Tegan’s first paper is also out this month. Here’s the citation:

Padgett T, YF Wiersma. 2020. Arboreal macrolichen community composition and habitat associations. The Bryologist. 123(1), 64-74,

January 2020

Happy new year! We started off the semester with a snow day, so let’s see what that means for the rest of the term! I’m looking forward to teaching Conservation in Practice with Bella (she’ll do 3 classes as part of a graduate teaching experience program), the Science Atlantic meeting in March, and preparing for the IALE-North America meeting in May, while also working on some writing. Oh, and some skiing when I’m not working…

Congratulations to Tegan, on her first paper acceptance (a chapter from her thesis which she completed last year)! This is the first paper from the LESA lab this year, and my first publication of the new decade! Woot! It’s coming out in the Bryologist; I’ll post a link when it’s out.

Padgett T, YF Wiersma. In press. Arboreal macrolichen community composition and habitat associations in boreal forested wetlands of Newfoundland, Canada. The Bryologist.

December 2019

The final paper of 2019 is out. This one uses our lichen model system to test the conservation planning question of how much is needed to represent all species (which was the topic of my PhD but at national-extents).

Wiersma YF, RT McMullin, DJH Sleep. 2019. Model systems to elucidate minimum requirements for protected areas networks. Scientific Reports 9, 19594.

In honour of the holiday season – here is a photo of the “Christmas Lichen” (Cryptothecia rubrocincta), taken by yours truly this past summer, in Lettuce Lake State Park, Tampa, FL. Happy holidays to you and yours, from the LESA lab.

I had a fabulous time this month leading a really enthusiastic group of about 20 people from Nature NL on a hike to learn about lichen. Thanks Sara Jenkins for these amazing photos! It was a cold, wet morning but we had a great time and even introduced people to Boreal Felt Lichen!

Congratulations to Tom on passing his Honours thesis defense!

October 2019

This has been an exciting month and it’s only 2/3 over! Last week I got to take a film crew from River Road Films (Makers of “Wild Canada” and “Wild Canadian Year” productions for CBC’s “The Nature of Things). They are filming for the next CBC Nature of Things series “Wild Canadian Weather” (good call, coming to Newfoundland for that). I helped them gather some lichen footage in the “fog forest” for the episode on rain/fog. We drove through fog and heavy rain and then lugged gear out, just as the sun came out (ironic). It did cloud over and they have a few cinematic secrets they let me in on (I won’t tell). It was super fun living vicariously as a wildlife filmmaker for a day – as that’s what I wanted to be when I was 12. The series should be out next fall.

Tegan came back to campus for her convocation and got to celebrate with some family members. It was a beautiful fall day for pictures outside (as well as some lichen hunting). Thanks Travis and Tegan’s mom for the photos!

Bella and Travis are presenting their research at the Atlantic chapter of the Canadian Association of Geographers this month.

New publication from the lab – just accepted:

McMullin RT, YF Wiersma, JC Lendemer, SG Newmaster. In press. Risk assessment and conservation strategies for rare lichen species and communities threatened by sea-level rise in the Mid-Atlantic Coastal Plain. Biological Conservation.

A fond farewell to Patrick (and his sidekick the famous Finnegan) who left at the beginning of this month on a road trip back to Ontario, where Patrick will be starting a PhD in May. Stay tuned for updates on Patrick as he puts the final pieces of his MSc thesis together!

September 2019

Happy academic new year!

This year kicks off with a publication – a short letter Troy and I wrote in response to a letter critiquing our piece in Frontiers in Ecology and the Environment that came out last April. The citation is:

Wiersma YF, RT McMulllin. 2019. RESPONSE LETTER. Out with indicators: in with biodiversity (Response to letter from Janssen et al.) Frontiers in Ecology and the Environment 17: 371-373.

Welcome to a new resident of the lab – Katherine Flores. She is a Masters student in Environmental Science at the Grenfell campus, where she is co-supervised by Andre Arsenault and Michele Piercey-Normore. I am on her committee, and while she is on the St. John’s campus doing course work, she’ll be in my lab group.

… and as we welcome a new student, we’re preparing to say good-bye to another lab member. Patrick gave his exit seminar to a packed house, and got the great news a few hours later that one of his chapters had been accepted for publication. Way to go Patrick!

2019-09-13 14.27.33

September is also the month for the Newfoundland (Mushroom) Foray. I went this year, and was thrilled to be joined by two current lab members along with two alumni. Check out this fine group of women in the pic below!


August 2019

Congrats to Tegan on submission of a chapter from her completed thesis as a manuscript for publication. Fingers crossed! Also, good luck to you as your start your new job at Terra Nova National Park this month.

In other lab news, Patrick was just at the ABLS/Botany meeting in Tucson, Arizona presenting his lichen predictive models. Congratulations to Patrick on being one of three “Honourable Mentions” for the A.J. Sharp Award for best student paper presentation! My collaborator Troy McMullin from the Canadian Museum of Nature was also there presenting some of our ideas on “old growth” vs. continuous forests.

I had a little work trip to Tampa, FL, and despite the heat and mostly indoor meetings, I got an hour of hiking in at a Bald Cyprus swamp. I added a new lichen for my “life list” that I was super excited about – Cryptothecia rubrocincta (aka “the Christmas lichen”).

2019-07-23 08.11.52

July 2019

“Summer” kicked off with a week of field work with visiting colleague and lichenologist from the Canadian Museum of Nature, Dr. Troy McMullin (it actually was rather surprisingly summer-like weather). We had fun climbing the Hawke Hills, joined on various days by Tegan, Patrick, Felicity and Finnegan, where we discovered many cool species of arctic lichens. It will take some time to compile the data, but we plan to eventually get some kind of a publication out of it! Field pics (photo credits to Patrick) below.

Bella and Gabby are rockin’ it in Bloomfield – getting lots of home range data on our snowshoe hare (aka “the buns”). I spent a week with them and visiting volunteer Adam who was a trooper about our kalmia meadows and dense spruce that require rugby-like tactics to lay a transect through.

Congrats to Travis for submission of a chapter of his PhD to a journal. Fingers crossed! Patrick had a positive set of reviews come back on a thesis chapter – we’ll post more news when decisions are finalized…

And in graduate news, newly minted MSc Tegan just accepted a 6 month contract at Terra Nova National Park, where she is coordinating a park lichen survey with a focus on listed species. She starts August 1st and we’re glad to be keeping her in the province for a little while longer.

June 2019

Last week was convocation – congratulations to MES grad Matt Murphy. Sadly, I had to be in Terra Nova for the day, so I missed his ceremony and don’t have any pictures.

As part of convocation week, the School of Graduate Studies held an awards ceremony. Tegan (who is done but attending the Fall Convocation) was recognized as a Fellow of the School of Graduate Studies.


And in non-convocation awards, Travis received Nature NL’s “Wild Things” Scholarship in recognition of his volunteer efforts towards nature and conservation in the province. Here’s a story about his award.

May 2019

Huge congratulations to Tegan, who has now officially submitted her MSc and completed her degree!

Tegan is also busy in her part-time job with the NL Mosquito Project. She is up in Happy Valley-Goose Bay this week presenting at the Labrador Research Forum. Her poster was awarded second prize! Congrats!

Tegan wins silver in the poster category at the Labrador Research Forum (photo credit: Carissa Brown)

Last month was a busy one – the Biology Grad Student Symposium at the beginning of the month was a huge success. Patrick, Bella and Travis all gave excellent talks, and Tegan contributed a poster. Our lab enjoyed hosting the keynote speaker, Joel Brown, and taking him out for a spectacular day in the field.

In other news, Bella is busy getting ready for her field season and Patrick and Travis are out in Terra Nova teaching the Boreal Ecology field course for two weeks. Yolanda is presenting some research in the community at one of St. John’s “Pint of Science” events. All we really need is some spring weather (it’s been snowing lately!).

April 2019

Congratulations to Bella, whose co-presentation at the Aldrich Conference late last month was awarded a “best presentation” award! Bella is also at the Benthic Ecology meeting this week (here in town), presenting a poster based on her project for her stats course.

Congratulations to Travis, who was Memorial University’s recipient of the 2019 ESRI Canada Graduate Scholarship!

2019-03-25 17.06.10

Travis’ interview (in his role as CPAWS-NL Director) last month about the proposed Eagleridge Mine Development has been captured as a CBC News story. Read it here.

My Conservation in Practice Students (BIOL 4651) were interviewed on VOCM “Sunday Drive” about their term project. I had nothing to do with this – they inititated it all on their own! Very proud of these undergrads. They’ve made a website to go with the project – check it out here.

March 2019

Congratulations to Tegan on the submission of her MSc thesis for examination! The finish line is in sight!

Kudos to Patrick for hard work revising and resubmitting a manuscript that is also going to be a chapter in his thesis.

Bella will be co-presenting work done as part of her stats courses at the upcoming Aldrich Interdisciplinary Graduate Resarch Conference 

Last month the LESA Lab was on the road, making two presentations to local community/naturalist groups. This week we are furthering our public engagement with all kinds of media interatctions.

First off, PhD student Travis (wearing his CPAWS director hat) has a letter to the editor in the St. John’s Telegram. Read it here. The study he refers to is the little foray Bella, Tegan and I did late January. He was also interviewed on CBC Radio on the Central Morning show.

There will be more “media splashes” in the coming days. Stay tuned – I will post them as they go live…

  • Tegan was on the St. John’s Morning Show (CBC Radio) talking about the mosquito project she’s involved in (unrelated to her thesis work). You can listen to her interview here.
Tegan at the CBC
  • Press release about a new paper I am co-author on just came out in Frontiers in Ecology and the Enviornment. Citation and link below:

McMullin RT, YF Wiersma. 2019. Out with OLDgrowth, in with ecological continNEWity: new perspectives on forest conservation Frontiers in Ecology and the Environment.

  • Article in the MUN Gazette about the above paper.
  • The Canadian Press did a story about this paper; it got picked up by various outlets, including CTV News, the Winnipeg Free Press, the CBC, and the National Post.
  • Troy was interviewed on the NPR show “Science Friday” about the story. You can listen here.
  • And in a final outreach activity – we’ve launched a new website that is aimed at educating the general public about rare lichens in the province. This is part of a project funded by Enviornment and Climate Change Canada. Thanks to Tegan, Travis and Patrick for their work creating it and to my collaborator Troy for help with photos and translation. Check it out here.

February 2019

The LESA Lab is hitting the road with public talks this month! I’m giving a talk this month the the Wildflower Society of Newfoundland and Labrador (Tuesday Feb. 12, 7:30 at the Botanical Gardens, if you are in town). They told me they were tired of wildflower talks and wanted to learn about lichens… The week following, Tegan is talking about her MSc work with the folks at Nature Newfoundland (Thursday Feb. 21, 7:30 pm, location TBA).

Congratulations to Bella on a successful first committee meeting!

We had a couple of end-of-month field excursions last month. Patrick and Travis travelled to Terra Nova and Conne River for a lichen workshop right at the end of January, and Tegan, Bella and I spent a wintery day looking for boreal felt lichen on the Avalon. Below are a few pictures.

In publishing news; two papers I was involved with have moved to “in press”. Links to pre-prints/re-prints will be coming soon.

January 2019

Happy new year! We’re all just getting back in the groove after a nice break. Tegan and Travis had some exciting bird, insect and lichen sightings on their trip to Mexico over the break (and they brought back really good coffee!).

I’m teaching two courses – Conservation in Practice and the Environmental Science seminar. It should be a busy winter.

Here’s a reprint of my first publication of 2019 – a letter in Diversity and Distributions.

Best of all – we have loads of snow!

December 2018

There is lots of exciting lab news to announce:

  • Congratulations to Patrick, who just submitted his first paper to a peer-reviewed journal!
  • Congratuations to Matt, who passed his MES exam (final paper) and will graduate at the end of this semester!
  • Congratulatons to Tegan, who delivered her MSc exit seminar at the end of November! She also submitted her first chapter to a journal for peer-review. Nice work!

November 2018

In lab news, congratulations to Travis and Patrick who contributed to organizing the Atlantic Society of Fish and Wildlife Biologists Annual symposium. They both presented papers, as did Tegan, who awarded 2nd prize for best talk (pretty cool to see a lichens & wetlands talk win at a wildlife meeting!)

Tegan giving her talk

In other news, lab alumna Rachel Wigle just landed a full-time job that is Biology related (though not in ecology). She is working on Quality Assurance in a greenhouse with Aphira. Pretty cool to have a former student get hired in the marijuana industry within two weeks of it being legalized here in Canada…

In other conference news, I am participating indirectly in the big Caribou Confab in Ottawa; I’m a co-author on a paper led by Ronnie Drever of the Natural Conservancy, which was presented by Chantal Hutchison.

Next week we will say good-bye to our “Ghost-Doc” Carly Ziter who is off to start a tenure-track position at Concordia. I’m sure she will do some awesome trailblazing to advance the field of urban landscape ecology in Canada!

In my role as an Associate Editor for the Journal of Applied Ecology, I recently wrote a blog post about one of the papers I handled. “Holiday snapshots can help us to understand conservation sites

October 2018

Big congrats to Rachel Wigle, who passed her MSc examination right at the end of last month!

I had the opportunity take part in the NL Mushroom (and lichen) Foray at the end of the month, which was a lot of fun.

Happy Academic New Year! Here’s a quote for everyone starting their school year from the author of “The Hitchhiker’s Guide to the Galaxy”.

This semester we welcome a new lab member, Bella Richmond, who is starting an MSc and joining the TERG project.

Here’s a link to the first pub of the 2018-2019 Academic New year. It was accepted almost a year ago, but only just came out in the journal (sometimes there is quite a backlog…). Lead author is LESA Lab Alumnus Shad Mahlum, now doing his PhD in Norway. It was published in Restoration Ecology and also features my colleagues Dave Cote (DFO) and Blair Adams (Newfoundland and Labrador Department of Fisheries and Land Resources).

August 2018

It must be dog days of August, as I am late updating the website. Here are recent news items from the lab (quite a lot for what’s assumed to be a slow month):

  • Congrats to Rachel for submitting her thesis for examination!
  • Congrats to Tegan on finishing her field work!
  • Patrick’s field work is coming along well. We’ll try to post some field work pictures soon.
  • Rachel presented her thesis work at the CSEE-SCEE meeting in Guelph last month
Rachel at CSEE (photo courtesy Carissa Brown)
  • Yolanda presented some new work at the NACCB meeting in Toronto last month
  • Travis has been out in and around Terra Nova helping with snowshoe hare telemetry and collecting some more field data for his PhD
  • My colleagues in Information Systems (Jeff Parsons and Roman Lukyanenko) and I had a paper accepted in the prestigious IS journal MISQ (Management and Information Systems Quarterly)
  • We welcomed a new “member” of the lab – we just purchased a new field truck (“Betty”) and retired our faithful little Ranger (“Lester”)

July 2018

Welcome Betty!

Two big announcements from the end of last month:

  1. Congrats to Travis on passing his PhD comprehensive exam!
  2. Good bye and good luck to Rachel, who left us at the end of June to return home to Ontario. She has a thesis draft off to her committee and should be submitting it for examination soon.

In other news, Tegan and Patrick are making good progress on their field work. Yolanda has been scoping out some sites for fall field work, and Travis will head out to Terra Nova soon to help with snowshoe hare telemetry.

June 2018

Field work is underway despite the colder weather we’ve had for end May/early June.

Congrats to Patrick on his convocation for his BSc last week!

Late last month I ran a workshop advising scientists on how to collaborate effectively with social scientists as part of the ACCESS meeting. A web page with workshop info and resources for anyone else who might be interested is here.

May 2018

The teaching term is over (though I am teaching a grad GIS course this summer) and that means FIELD WORK! Yay!! Patrick and I got an early start (last week’s nice weather motivated us) and are running a little experiment locally which involves more “fake lichens” (a neat little tool we developed for Rebecca’s Honours thesis). It’s a fun exercise and will give him some good estimates of his sampling error rates.

2018-05-01 11.54.57
Can you spot the fake lichen?

Field season also means new field personnel. Welcome back to John , who is joing the LESA lab as a summer student for the second year in a row. Also welcome to Brian, our new field assistant. Watch for pictures and news coming soon!

May gets to a busy start with the Canadian Society of Zoology meeting here on campus. Travis is presenting a talk, as are colleagues from across the department. The following week, a crew of us from the TERG project will head up to Terra Nova National Park for their annual “Research Day”.

And in a BIG milestone, Rachel is giving her MSc exit seminar this month! She is nearly done writing up and is doing her final presentation to the Department on May 9. Come on by if you want to here “A tale of two trees” (lichen community patterns on yellow birch and balsam fir on the Avalon Peninsua). Her research is highlighted in a recent article in the Gazette. You can read it here.

Rachel rockin’ it at her exit seminar

April 2018

HUGE congratulations to Tegan, who was awarded the Culberson and Hale Award from the American Bryological and Lichenological Society. Nicely done Tegan!

April means two of my favourite events of the whole year are upon us. Sadly, this year they overlap, so I will miss one of them.

The first is the “Landscapades” (as I call them) – officially the annual conferecne of the US Regional Association of the International Associaton of Landscape Ecology. This year the meeting is in Chicago. I’m hosting a sympoisum on “Experimental Landscape Ecology”, and Tegan is presenting her chapter 1 work. Read all about the meeting here.

While Tegan and I are off in the Windy City, the rest of the folks will get to attend the Biology Grad Student Symposium. Rachel is giving a talk, and Travis is presenting a poster. It should be a great day – check out the details here.

Also, congratulations to Molly M; a high school student I mentored for her independent Biology project for the IB program. Her work has been accepted for publication in Evansia.

March 2018

  • Congrats to Tegan and Travis for successful committee meetings promoting their work!
  • Tegan is off to Halifax this month to participate in the Forested Wetlands workshop.
  • Rachel is hard at work planning the BGSS, which should be a great event next month.

February 2018

Travis recently presented his work at a meeting of Nature Newfoundland. Read about the event here – this is an annual showcase of graduate student research that Nature NL hosts. Nice job, Travis!

A couple of papers accepted late last year just officially went in print this month. The first is in Landscape Ecology. You can find it here (it’s open access).

January 2018

Happy new year! 2017 was a productive year for the LESA Lab, some great field work got done by Rachel, Tegan and Travis – we look forward to seeing results as they work on their analysis.

I managed to get a few papers out last year, but counting on my grad students to carry the torch this year – at least for the first part of the year! I’ll be busy this winter teaching two 4th year courses, Landscape Ecology and Conservation in Practice.

Also, a welcome to new MSc student Patrick Lauriault. His profile should be up soon.

Congrats to Tegan, on acceptance of her abstract to the upcoming US-IALE (US Regional Association of the International Association of Landscape Ecology) meeting. She and I will be travelling to Chicago in early April to participate in the meeting.

Here’s to another great year of landscape ecology!

December 2017

Congrats to grad students Tegan and Matt for completion of this semester’s course work. Tegan is now all done course work, while Matt has a few more to go.

Kudos to Travis for sharing our TERG resarch (involving me, Shawn Leroux, Eric Vander Wal, and Shawn’s student Matteo) at last month’s Geomatics Atlantic Conference.

And, a final paper acceptance for 2017 just came through… I’m really proud of this one!

November 2017

November kicks off with two papers accepted… not bad!

First off – congrats to alumnus Shad Mahlum who took the time and put in the effort to do a additional analysis post MSc (effectively equivalent to another thesis chapter), which we published in Restoration Ecology. This paper looked at data on fish movement across 4 restored culverts in Terra Nova National park. We compared how one would intrepret “success” with different metrics and using a full BACI (before-after-control-impact) vs. a B-A or C-I comparison.

Mahlum S, D Cote, YF Wiersma, C Pennell, B Adams. Accepted. Does restoration work? It depends on how we measure success. Restoration Ecology.


Also my colleague Darren Sleep (NCASI) and I had a paper accepted from a project we’ve been chipping away at for awhile. We did some simulation modelling to assess how much protected area would need to be allocated in the boreal forest ecozone under different target scenarios.

Wiersma YF and DJH Sleep. Accepted. The effect of target setting on conservation in Canada’s boreal: what is the right amount of area to protect? Biodiversity and Conservation.


October 2017

The TERG crew is having great success catching hare in and around Terra Nova! Nine caught so far. We now have at least one VHF collared hare in three of our four grids. Woo hoo! As a Thanksgiving day bonus, Tegan (who came up to help out) found a rare blue felt lichen (Degelia plumbea).


Rachel wrapped up her field work (for good) and is now on to lab work – anlaysing bark pH and aging tree cores.

Travis and Tegan, along with fellow grad students on the TERG project are off to Terra Nova to do some snowshoe hare trapping. Hopefully we catch a few more bunnies this time of year! Too bad wild bunnies aren’t as amendable to capture as domestic ones.

2017-05-16 15.38.20

And in publication news this month, two papers from this lab have been recently accepted. Watch this space for links to the post-prints, when they become available. Congtats to fomer LESA lab student Matt on his first publication (carried out with my colleague Max Liboiron) which documents a new protocol for monitoring marine debris on rocky coastlines.

Also congrats to Honours alumna Rebecca on her first pub! We combined her honours work (which compared methods to survey rare species) with extensive survey work by Rachel, Tegan and I last fall, along with data from our colleages Blair and Dave to do this paper.

Bowering R, R Wigle, T Padgett, B Adams, D Cote, YF Wiersma. Accepted. Searching for rare species: a comparison of two methods for detecting and estimating abundance. Forest Ecology and Management doi: /10.1016/j.foreco.2017.10.016.

September 2017

Happy Academic New Year!

Tegan has wrapped up her field work and Travis finsihed up a large amount of plant survey work. He’ll head out this fall to help with snowshoe hare live trapping, and Rachel and I are going out to do a few lichen surveys locally this fall.

In publication news, my colleagues Shawn Leroux and Eric Vander Wal, with a pile of grad students, have a paper accepted in Ecology Letters on our Ecological Stoichiometry work! Details to follow.

As well, Miguel’s second paper is now out in the Wilson Journal of Ornithology.

February 2017

Rachel, Tegan and I are busy slowly working through some lichen specimens in the herbarium which were collected in 1967 and are unidentified. We got curious about the collectors, so we wrote an article, which came out this week in Omphalina (the publication of the NL Foray). Thanks to everyone who helped out with gathering/taking images for the article.

We are hiring some summer field assistants! (at least two of them). One will be open only to students holding an NSERC USRA or a Memorial University USSIP or SURA. Students should apply to USRA/SURA/USSIP first, then my lab. The other will be open to undergrads in general. The first job advertisement is here.

January 2017

Happy new year! The past year was a productive one. In 2016 we welcomed two new students (Travis and Rachel) and said good bye to Emilie who took a job with the Ontario Ministry of Natural Resources. Add to that a LOT of field work, a workshop (for me) in Germany and a few publications and it was a good year.

Congratulations to Miguel Mejias, who passed his MSc examination and officially completed his degree this month.

The new year is a time for lists about the past year. In that vein, an editorial I wrote with colleagues Dr. Parsons and Dr. Lukyanenko in Conservation Biology was listed as one of the top accessed articles in that journal of 2016. Pretty cool!

Welcome to our newest student, MSc candidate Tegan Padgett. Check out her profile under “Current Personnel” tab.

December 2016

Just got word that an editorial I wrote with colleagues Dr. Parsons and Dr. Lukyanenko in Conservation Biology was listed as one of the top accessed articles in that journal of 2016. Pretty cool!

My colleague Dr. Troy McMullin (who worked as a post-doctoral RA in the lab last year, and is now lichenologist at the Canadian Museum of Nature) and I recently had a paper accepted. This was a “side project” during his time here in Fall 2015, but it got us a nice pub!

Happy Academic New year! I’m on a mini-sabbatical, so will be hunkered down writing up some papers and grants, with forays to the field interspersed.

This fall we are welcoming a new MSc student, Rachel Wigle – watch for her profile on the lab personnel page.

A new paper is out that I co-authored with my colleague Dr. Darren Sleep of the National Council for Air and Stream Improvment.

August 2016

It was “dog days” of August at the LESA lab – finishing up field work, and taking some vacation time.

July 2016

I spent a fun 5 days helping the TERG crew with some vegetation sampling. Here’s the crew after completion of the entire plot!

I’m also off to Germany this month, to Stuttgart and the Schwarzwald (Black Forest) for a workshop on Citizen Science with my colleague Dr. Wachinger, who was a visiting researcher in my lab last fall.

May 2016

Welcome to our newest graduate student, Travis Heckford (MSc student) who will be part of the TERG Team. His profile should be up pretty soon. In the meantime you can peruse his personal website here.

I also have two undergraduates joining the lab this summer. Olga Trela is doing a USRA in my lab for half the summer and Rebecca Bowering just started her Honours research with me. Look for their profiles on my “people” page soon.

An editorial in Conservation Biology that I co-authored with my colleagues Roman Lukyanenko and Jeff Parsons is now out in an issue of Conservation Biology that also contains a special section on Citizen Science, which is worth checking out. The citation is:

As AE for Journal of Applied Ecology, I was asked to do a blog post related to a recent paper I handled on seagrass habitat modelling. You can read it here.

Woot! I got out of the office this month! It wasn’t a lot (mostly a lot of driving and a day meeting with Terra Nova parks folks) but me and da b’ys (TERG grad students) did get to do some preliminary scoping of field sites, see what a hare grid looks like, and introduce Matteo and Travis to boreal vegetation.

April 2016

This month was the Biology Graduate Students Symposium. It’s a one-day event designed to let students showcase their research. I always look forward to it as it’s such a great event and gives me a chance to hear about all the cool research going on. This year was no exception. Kudos to the organizing committee on another successful symposium. A highlight for me this year was that one of my students, Miguel, was voted for the Joe Brown People’s Choice Award for best talk. This rather, um, phallic, trophy gets to sit in the lab for the whole year before being bestowed on next year’s winner (for the curious, that is a bone from a seal bacculum – the trophies are all handmade and reflective of Newfoundland’s distinctive fauna). Congrats Miguel!

Matt is starting the month by travelling to beautiful Asheville, North Carolina to present his Fogo Island work to landscape ecologists at the US-IALE meeting. The conference website is here and if (like me) you can’t be there, you can follow the Tweeters using the #usiale2016 hashtag.

Congrats to PhD student Emilie Kissler who has been offered a permanent position with the Ontario Ministry of Natural Resources. She’ll soon be relocating to Timmins, in northern Ontario.

March 2016

Here’s a link to an article in the St. John’s Telegram (March 15) about Dr. Troy McMullin’s work, done while he was working here last October.

Happy International Women’s Day (March 8th). Several editors of Journal of Applied Ecology (including me) have contributed to a blog post on perspectives of women in science. Check it out here.

My colleagues Roman Lukyanenko and Jeff Parsons and I have had an editorial on the topic of data quality and citizen science accepted for a forthcoming issue of Conservation Biology. The citation is:

Matt is off to beautiful Banff in the first week of February for a week-long MEOPeer session.

January 2016

Happy new year! Looking back, I would say 2015 was a pretty successful year in the lab. Wewelcomed two new students (Krista and Matt; both of whom are making great progress on their papers) and hosted 3 visiting researchers (Jennifer from U Manitoba last April and Dr. Wachinger from the University of Stuttgart and lichenologist Dr. McMullin in the fall). We also saw the successful completion of Emma’s MA thesis and Rachel’s Honours thesis. Top that off with some successful grants and publications and it’s been a good year. I’m sure 2016 will bring more exciting activity in the LESA Lab.

  • Congratulations to Andrew Roberts on completion of his MES degree!

Please take note of the event below, hosted by my collaborator Dr. Max Liboiron

Marine Plastics in Newfoundland Fish and Ecosystems: A Public Meeting

Thursday, January 21


Petty Harbour Recreation Center

Cribbies Road, off Main Road next to the War Memorial

While plastics have been found in every ocean in the world, the exact amounts and effects of plastic pollution in Newfoundland are unknown.

A team of research at MUN have started a long-term study of marine plastics in Newfoundland by collecting cod guts from the September 2015 food fishery to see of cod are eating plastics. They will present their findings at this public meeting, discuss the issue of marine plastics more broadly, and collect input from attendees about the types of concerns they have around plastic pollution in Newfoundland to direct future research.

Everyone is welcome to attend!

 For more information, contact project leaders at MUN: Dr. Max Liboiron (Sociology & Environmental Sciences) & Dr. Charles Mather (Geography)

December 2015

My visiting colleague, Dr. Gisela Wachinger, from the University of Stuttgart, Germany are having some productive focus groups and interviews with users. I am also learning a lot about Germany’s newest national park, Schwartzwald (Black Forest) and we are working to develop a proposal for future collaborations examining issues and conflicts in and around national parks; comparing Canadian and German case studies.

This month features a second visiting researcher to the lab, Dr. Troy McMullin, a lichenologist from the University of Guelph. He and I are collaborating to make links between boreal forest landscape ecology and lichenology. You can see some pictures of his trip here.

September 2015


We are happy to see Matt safely back from his 4 months of field work on Fogo. He’s got lots of great data and maps. Also we are happy to welcome back Andrew from his work term and adventures in Labrador – he’ll be busy finishing up his major paper this term.

We’re also welcoming our newsest LESA Lab member – Krista Byrne-Puumula, who is doing an MES related to citizen science and marine plastics (co-supervised by Dr. Max Liboiron).

Also a warm welcome to visiting research, Dr. Gisela Wachinger, from the University of Stuttgart, Germany. She and I are collaborating on research with our users to find out why they use the site, and solicit ideas for ways to make the site better. We’re also working to develop a proposal for future collaborations examining issues and conflicts in and around national parks; comparing Canadian and German case studies.

In funding news, my colleagues Dr. Leroux, Dr. Vander Wal and I recieved a grant from MITACS to support 3 students in our Terrestrial Ecology Research Group.

August 2015

Check out the new website for a collaborative research group in Terrestrial Ecology that I am a part of! Visit it here.

Summer is always a bit of a blur of research activities and writing, plus squeezing in some fun and R & R.

I recently got back from a few days on Fogo with my colleague Max – we went to visit Matt in the field. We got out on a fishing boat to check cod pots, and worked out a new beach survey protocol (dubbed “the Fogo protocol”) to survey for marine microplastics on rocky beaches. We also visited one of the 4 corners of the earth.

And, in a few of the sunny days we had, I caught some rays and worked on some papers.


Finally, a special issue on the topic of “Protected Areas and Sustainable Forest Management” which I edited is out in Conservation and Society. See the complete Table of Contents here.

July 2015

Yikes, it’s the middle of July and I’ve not updated the website. Things must be busy! Students are all at work (see Andrew’s work term guest blog here) or in the field. Matt is still up on Fogo and a team just got back from two weeks of hard work on the northern Peninsula. Matt sent this awesome photo from Fogo…

I was recently in Portland, Oregon for the IALE World Congress. It was great. I guess between co-ordinating field work, getting ready for the congress and travelling, I have not updated here. I saw lots of great talks from all over the world, and it seemed that every Canadian landscape ecologist was there too. In honour of hard-working Canucks in the US, here’s a photo of a sculpture just outside the hotel in Portland.

The first of May brought some good-byes… a few shorter, a few longer.

We’re sad to say good-bye to our new friend and colleague Jennifer Doering, who visited the LESA Lab for a couple of weeks from the University of Manitoba to learn some landscape ecology and spatial analysis techniques to intergrate with her Masters research on genetic variability in lichens. You can read a bit about Jennifer’s experience by clicking here.

Jennifer D adjusting to NL wind and topography from flat Manitoba. She adapted quite quickly and learned to appreciate our lichen-friendly climate.

Matt left for his 4 month field work on Fogo Island. Looking forward to hearing about his adventures… perhaps we will get him to guest blog from out there.

Andrew will also be taking some time away from the LESA Lab while he does his 4 month co-op work term with Sikumiut Environmental Management. It sounds like he will have some neat travel up to Labrador and will be picking up some new skills along the way.

April 2015

The end of April is lichen-themed! We’re please to welcome MSc student Jennifer Doering, from the University of Manitoba as a visiting grad student for 2 weeks. As well, Andrew is busy experimenting with a hyperspectral camera for lichen research.

Congrats to lab alumna Karla, who has a paper (based on her honours thesis) accepted in Avian Conservation and Ecology-Écologie et conservation des oiseaux. The citation is:

Congrats to lab alumna Karla, who has a paper (based on her honours thesis) accepted in Avian Conservation and Ecology-Écologie et conservation des oiseaux. The citation is:

Letto KR, YF Wiersma, J Brazil, B Rodrigues. Bald eagle (Haliaeetus leucocephalus) population increases in Placentia Bay, Newfoundland – evidence for habitat saturation? Avian Conservation and Ecology.

Good news for my colleagues Dr. Vander Wal, Dr. Leroux, and I. We’ve each been awarded a research grant to start some integrated research encompassing population, ecosystem and landscape ecology in boreal Newfoundland.

The first paper based on sightings from is out. This is based on a sighting of a new mosquito species to the province, which was made by a member at Entomologists at Memorial University confirmed it, and have published the report of this new occurrence in The Canadian Entomologist. Read it here.

The is a lot going on this month related to the Fogo Island project. Matt and I are heading to Fogo at the end of the month with Matt’s co-supervisor Max Liboiron and guest visitor Pheobe Sengers for a meeting with the fishermen to develop research quesitons further.

Phoebe is on campus this month and doing several events related to Change Islands (next door neighbour of Fogo). Read about them here.

On February 9, Roger Tomlinson passed away. He is a Canadian known as the “Father of GIS”. You can read a tribute here. I had the amazing good fortune of interviewing him for the (then fledlging) Society for Conservation GIS back  in 2000 when I was beginning grad work and just discovering GIS and landscape ecology. I’ve dug it out and posted the interview here (I can’t believe I found it in a box! Guess I’m a packrat)… you can still buy the edition of the magazine Conservation Geography – edited by Charles Convis – that it was published in at the ESRI store.
