Happy International Women’s Day! We are grateful to the incredible women who lead (and have led) the Canadian Society of Ecology and Evolution, & to all the women ecologists & evolutionary biologists across Canada for their important work. You help make our society, country, & planet a better place!

Heliconius erato demophoon sat on a pink, yellow and white lantana flower. The left side of the butterfly is white, while the right side is the usual black and red, but with some white clonal patches.

New preprint form me and the McMillan lab at STRI and Martin lab at GWU, digging into scale cell type specification and differentiation in Heliconius wings, with some insights on the lncRNA gene ivory.

The incredible vulnerability that reproduction poses for plant species in a warming world

Crop scientists have long recognized that reproduction is going to be the first point of failure for plants with rising global temperatures. However, this has often been overlooked by those studying natural populations. In this new review, we try to change that. ecoevorxiv.org/repository/v...

Methodological illustration for asking whether X affects plants. β€œQuestion” provides an example of a question that both ecologists and evolutionary biologists ask, with categories of traits often of interest. β€œExperiment” shows trait examples and comparisons (populations, environmental, across time). Types of traits are where evolutionary biologists could expand their breadth. β€œOutcome” describes lasting effects of whether X affects traits to the point that it is passed on and contributes to future generations or it leads to extinction. β€œOutcomes” is where ecophysiologists could expand their work.

My grad student, who got RWR and appealed, got an email from GRFP program today that said "Your application was screened by NSF program officers with expertise in your proposed field of study and was determined to be ineligible according to the solicitation requirements."

How does population density affect evolutionary trajectory?

Microbes construct their own niche which in turn reshapes their evolution.

Preprint drop from grad student @noahhoupt.bsky.social whose evolution experiments featured blue/white colonies, 1000 generations, a lab move, and much more!
