What underlies plasticity and persistent enhanced growth following warm temperature exposure?

We sequenced lake sturgeon muscle tissue to find out

A variety of molecular mechanisms and cellular changes work together to increase muscular development across timescales

Interested in the genomic, behavioral, and morphological drivers of bird evolution? The Weir Lab at UT Scarborough has PhD positions available!

Please share widely. As a current postdoc in the lab, I am happy to share my experiences with applicants.

New lake sturgeon work out investigating transcriptional shifts in the gill during early development

mRNA changes associated with histone modifications, DNA methylation, and apoptosis were conserved across both populations, as well as population-specific processes

Are gene expression responses to an immune challenge conserved over macroevolutionary time? Not so much... in a new preprint we measure & compare differential expression in response to an immune adjuvant, in 14 fishes sampled from across Actinopterygii

A short thread

Out in Global Change Biology,

We conducted a meta-analysis to assess the thermal tolerance and adaptive capacity of North American Sturgeons.

While sturgeons are incredibly thermally plastic, increasing temperatures limit their physiological capacity and likely recruitment🧪🐠🐡🌎

@eveliendegreef.bsky.social and I wrote a follow-up piece in @theconversation.bsky.social. It was great to write more about the context surrounding bowhead whale and narwhal genomics.

Excited to share our latest paper in Global Change Biology! 🐳Here we examined bowhead and narwhal genomics and the legacy of commercial whaling: dx.doi.org/10.1111/gcb....
