New from our lab: Using the invasive round goby as a model predator, we show how model selection in functional response experiments is affected by context (habitat complexity; mobile vs immobile prey). link.springer.com/article/10.1...

We have more #biodiversity data than ever — from 🛰️, field work, citizen obs., and Indigenous knowledge. But, are we halting biodiversity loss? The answer is uncertain. Why? Because the chain of evidence needs to be stronger Our new #PNAS paper proposes a way forward www.pnas.org/doi/epdf/10....

RIP Bill Leggett, PhD’69. Before he led Queen’s University as its principal, he was McGill’s chair of biology, dean of science and vice-principal (academic). Also a highly regarded expert on the dynamics of fish populations www.arbormemorial.ca/en/reid/obit...

One of the biggest questions in biology is how complex cells evolved about 2 billion years ago. Here's my new story on how scientists are solving the mystery of eukaryotes like us. Gift link: nyti.ms/4qMbo22

Maths and biology conspired to make something beautiful: the world’s largest floating leaf (genus Victoria), spanning up to 3 m across. We decoded this enigma with mathematical modelling to show the lattice is an economy of material– the most structurally efficient way to cover a large surface area.

New preprint from our big collaborative evolution experiment in 9 whole lakes in Alaska, written by McGill grad student @lucaseckert.bsky.social www.biorxiv.org/content/10.6... What happens if you put a mixture of multiple source populations together to complete & evolve in multiple new lakes?

Sea cucumbers spend their lives burrowing into and eating mud + sand. But this beautiful species—Enypniastes—is also capable of swimming by slowly undulating the cape-like structure around its top. And it's not a trick of the light: its organs actually glow in the dark, which may deter predators.
