For “Reflections on the history of modeling and theory”, @sarperotto.bsky.social and I met with Joel Cohen. We learn how he navigated math and biology, the value of embracing ignorance, and what is a population. Or really, what _isn't_ a population: www.youtube.com/watch?v=RCt9...

Estimating the rate of quantitative trait evolution in the presence of gene tree discordance by calculating likelihoods across trees

Quantitative traits provide insights into how phenotypes evolve across species. However, standard comparative methods often assume a single species tree and overlook the discordant gene tree histories...

New paper by former MSc student @christeinecke.bsky.social! ⭐ A behemoth effort to apply artificial selection on clonal reproduction in #Mimulus guttatus. We show that clonality evolves quickly, but not symmetrically in both directions, and multivariate life history traits are altered too! 🧪🌾

How many chromosomes can an animal have?

In our paper out now in @currentbiology.bsky.social we show that the Atlas blue butterfly has 229 chromosome pairs- the highest in diploid Metazoa! These arose by rapid autosome fragmentation while sex chromosomes stayed intact.

Excited to finally have the pre-print up for this work on evolutionary rescue from my PhD at UBC!

Previous theoretical work on the effects of negative density-dependent growth on evolutionary rescue has uncovered inconsistent results, leading to an incomplete understanding of its influence.
