The clock is ticking: How epigenetics could help save wildlife from collapse In polar bears, dolphins, baboons and more, molecular signatures of aging are changing how conservationists assess population health, resilience and risk

A new article in @knowablemag.bsky.social that highlights some of @levinewediuk.bsky.social's PD work with me and @colingarroway.bsky.social, along with many other efforts to bring epigenetic clocks into conservation efforts.

@levinewediuk.bsky.social and I take a critical look at the “bigger is better” hypothesis in young teleosts by combining longitudinal survivor studies in a global meta-analysis.

Curious to hear your thoughts!

Not so scary after all? Decoding the landscape of fear through hormonal responses to risky times and places Prey must balance the energetic benefits of foraging with avoiding predation risk. This risk-reward trade-off, a cornerstone of behavioural ecology, hinges not only on realized predation risk but also...

It’s a story of how animals perceive risk and the limitations of our human perceptions. Read the preprint to find out more! 5/5 doi.org/10.1101/2025...

So what’s going on? Looking closer at their GPS tracks hints at a clever strategy: forage in cropland, then duck into the forest to rest and de-stress. 4/5

Elk usually forage in cropland, which should feel risky.

But big surprise: their hormone levels don’t indicate they feel fear there. 3/5

We put that idea to the test by tracking wild elk and measuring two hormones that mean fear (glucocorticoids, or GCs) and refuelling (T3). 2/5

New preprint! 🚨

Predators hunt where prey forage. So, prey should be afraid of their favourite places to eat… right? 1/5

I am currently looking for an MSc student to join my research group for September 2025 to investigate moose habitat selection in the context of apparent competition in Ontario's Far North. Please share and contact me for further details!

Want to make an epigenetic clock for your non-human study species but don't know where to start? Check out our new preprint that guides you through the process!

Come be my colleague! We are hiring very broadly in cancer biology. Great colleagues and department, lots of support, sure the winter is cold but our hearts are warm!

NEW MSc POSITION! We're starting a new study system on eastern small footed bats in Ontario. Please share widely and/or apply if you're interested in foraging ecology, bats, and conservation! Link to application is here: docs.google.com/forms/d/e/1F...
