Excited to preprint our latest work (w/ Drew DeHaas, Zhibai Jia, Leo Speidel) on using ARGs for demographic inference. w/ applications using data from 1000 Genomes Project. www.biorxiv.org/content/10.1...

Inference of complex demographic history using composite likelihood based on whole-genome genealogies

Accurate parametric inference on complex demographic models is a continuing challenge in population genetics. Ancestral recombination graphs (ARGs) provide richer information than simple population ge...

Check out this cool visualization tool for ARGs by @kitchensjn.bsky.social!! Found it super helpful to visualize an ARG as a single graph and to look at marginal trees as part of the full graph.

James Kitchens @kitchensjn.bsky.social · Aug 19

Excited to share our new preprint for the tskit_arg_visualizer Python package! ARGs can sometimes feel like a black box, so
@yanwong.bsky.social and I have been developing a method to programmatically drawing these graphs.

Hey #ESEB2025 folk! I'll be presenting my work on describing evolution in finite populations at 11:30 am on Tuesday in S-03. Drop by to learn how taking ecology and variable population size seriously changes classic pop gen descriptions like the Price eqn, revealing novel directional eco-evo forces.

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.

New preprint! We analyzed ~500 global marine fish time series using #EmpiricalDynamicModeling and show that temperature variation amplifies nonlinearity in juveniles and adults, while life history mediates nonlinearity for the latter, dampening it in slow-lived species #Ecology #Fisheries

Temperature variation and life history mediate the degree of nonlinearity in fluctuations of global marine fish populations

Nonlinear dynamics readily occur in natural ecosystems and can drive irregular population fluctuations through oscillations, chaos and alternative stable states. However, the effects of anthropogenic ...
