Life stages of Fundulus heteroclitus. Mummichog, killifish, call it what you want, but know it is among the mightiest inhabitants of North America’s east coast estuaries

The Waddinton epigenetic landscape… for salmonids! The concept is that cells can roll downhill to their “endpoint” differentiated state. However, the landscape itself can be modified by various factors, “nudging” the ball into different valleys. Figure for Schulte Lab.

Understanding animal physiology in all its forms necessitates asking hard-to-measure questions. Until his retirement last year, @zoology.ubc.ca was lucky enough to have Bruce Gillespie create custom equipment for over 25 yrs, assisting us in quantifying our research. Here are a few of his creations.

Coho salmon (Oncorhynchus kisutch)

From the archives - a little different from my usual projects, but a rewarding one: Van Kam is a Canadian company owned and operating out of Western Canada for almost 70 years. A while back they asked me to help them visualize their core values: Care, Achieve, and Develop.

Recent paper from the lab of @tfrasierdna.bsky.social. The endangered North Atlantic right whale suffer from low genetic diversity and high mutation load, which can impact recovery. However, genetic purging has reduced harmful mutations, potentially contributing to future recovery.

New paper by Lamb et al. (@claytontlamb.bsky.social). Southern mountain caribou exhibit both vertical and horizontal migration, but migratory behaviours are under threat due to disturbances, particularly at lower elevations.

Happy Holidays! Due to the postal strike this card did not get the distribution it usually does, and those who get one expect it late. But the sentiment remains the same - I hope everyone has a kickass 2025!

And on behalf of Kuma and Yider, don’t forget, #adoptdontshop.

Happy Holidays from sunny Vancouver!

The number one highlight of 2023 was arranging for the adoption of Yider for my parents (Free Korean Dogs) and Kuma for us (Adopt Korean Rescue). The upgrade to my life has been immeasurable, mostly because these goofballs are a laugh a minute.

Marine snails are vulnerable to climate change, and their limited mobility combined with the rapid rates of summertime warming in the Strait of Georgia increase exposure risk. Fiona Beaty explored this in detail in her recent work, out now in Ecology. It was a treat illustrating this one!

Out now!!! Mark Bitter, Dmitri Petrov, and Paul Schmidt used a high-resolution time series to show finely populations can adaptively track fluctuating environments, and how this fine-scale detects fluctuation that would be missed with coarser sampling time frames.

But Elk Valley is a highly productive habitat that continues to draw in high levels of grizzly immigration, and thus, more human-bear conflict. Immediate conservation efforts are needed to support this special population of bears.

New paper by Clayton Lamb on the high grizzly bear mortality rates in Elk Valley, British Columbia. Human conflicts (ex: on properties), train, and car collisions are the primary causes of these deaths.
