Then on Thursday Iβm giving a talk on how outcrossing is favored under a combination of mutation and antagonistic coevolution (S51.10 - Sex).

Comparative study reports that sex differences in dispersal predict sex differences in cooperation across cooperative birds and mammals. Dispersal likely impacts sex-specific direct benefits or costs of cooperation:

βIssue 6 of JEB is now online!β
This issue is headlined by a Target Review from @josselin-clo.bsky.social et al. on #matingsystems evolution, accompanied by several #invitedcommentaries expanding on this key discussion comparing concepts in plants and animals:

Evolution 2025: first time presenting this work and first talk as a postdoc! Can we experimentally show Red Queen dynamics underpin a coevolving host-parasite system as per theory? Time shift assays reveal a promising signal. ππ»π
