NOAA aerial imagery is coming in. Hurricane Melissa literally turned western Jamaica from green to brown. Vegetation damage is immense — recovery will take years.

Stunning illustration of mimicry! Common cuckoo eggs (top row) imitate the eggs of their host species (bottom row). The 30 October issue of Science explains this dazzling coevolution with genomic data — though I admit, it’s complex enough that I’d struggle to teach it! 🧪🌿🌎🦉

Un renard arctique à Paris ! Merci à @audelalis.bsky.social de m’avoir fait découvrir l’exposition Désert au Muséum national d’histoire naturelle. Je visitais les lieux pour préparer une rencontre scientifique internationale qui, je l’espère, aura lieu au Muséum dans quelques années. 🧪🌿🌎🦊

'What makes PhD students happy? Good supervision. Supervisors who invest in positive mentoring relationships with their PhD candidates also reap the benefits for their own research.' Nature, 23 Oct 2025. I’m amazed this is framed as a revelation — it’s pure common sense. 🧪🌎🌐

Studying Arctic foxes on Bylot Island (Nunavut, Canada), or being studied by them? The collared fox in this photo is a male named Ram, captured this summer. Great shot by my excellent MSc student Laurianne Dumont. 🧪🌿🌎🦊 #MovementEcology #wildlife

Animals don’t know they’ll soon be released when we trap them for tagging. I couldn’t help but wonder what went through the mind of this Arctic fox as I held her (Bylot Island, Nunavut, Canada, summer 2025).🧪🌿🌎🦊

Last year I set up four polar bear sampling stations in our study area at Alert (Nunavut, Canada). Goal: collect pictures and hairs to document the understudied Arctic Basin population. This one, from 8 August 2025, is our first good photo ! 🧪🌿🌎🌐🦑🦊 (barbed wire for genetic hair collection visible)

You don’t need to love birding to enjoy Northern Gannets gliding at sunset over a calm sea. Picture taken during a boat trip off Prince Edward Island, Canada on August 4th, 2025.🌿🌎🦉🦑

Took hundreds of pictures this summer on Bylot Island (Nunavut, Canada), but only now had time to go through them. This molting Arctic fox giving a cute nose-lick while staring at me in the tundra is one of my favorites. 🌿🦊

Canids seem to be the routine lovers, reusing their travel routes more than felids. This shapes hunting, encounters, and even disease spread. Insights from 1,239 GPS-tracked carnivores, including the Arctic foxes we track on Bylot Island 🧪🌿🌎🌐🦊. Read in the latest PNAS at bitly.cx/TxI2

Pictured is a male jaguar (Panthera onca) equipped with a tracking collar. William F. Fagan et al. tracked the movements of 1,239 mammalian carnivores, including 16 canid species and 18 felid species, on six continents. On average, compared with felids, canids displayed a greater density of trackways within their range and were more likely to reuse established trackways. According to the authors, the evolutionary differences in carnivore movement patterns could aid efforts to model encounters among carnivores, prey, and humans. See the article by Fagan et al. e2401042122. Image credit: Sebastian Kennerknecht (photographer).

Can confirm that my NSF grant "How False Beliefs Form & How to Correct Them" was cancelled today because it is "not in alignment with current NSF priorities" Shocking that understanding how people are misled by false information is now a forbidden topic. Our work will continue but at a smaller scale

Rebekah Tromble @rebekahtromble.bsky.social · Apr 18

NSF has posted an “update on priorities.”

They’re canceling all “DEI and misinformation/disinformation” grants.

And the guidance on how to fulfill the longstanding, legally mandated Broadening Participation requirement is utterly incoherent.

A look at the extent of sea ice in the Gulf of St. Lawrence this winter compared to the rest of the satellite-era. Each line here represents one year from 1979 (purple) to 2024 (white). 2025 is in red.

Map of Arctic: zacklabe.files.wordpress.com/2022/08/b203.... Data: nsidc.org/data/seaice_....

Line graph time series of 2025's daily Arctic sea ice extent compared to each year from 1979 to 2024 as shown with thin lines in colors from purple to white. This graph is for the Gulf of St. Lawrence region. There is large daily variability, but a long-term decreasing trend is visible during the melt season months. A seasonal cycle is also visible in this region.
