Why do we not see evolutionary change in heritable, fitness-related traits in free-living populations? @erikpostma.bsky.social &co use the #evolution of clutch size in great tits to show the importance of gene flow in explaining contemporary evolutionary change and stasis 🧪 buff.ly/ngAKH6r
Scatter plot comparing individual breeding values at year t−1 and year t, with blue dots = survivors, orange dots = non‑survivors, green dots = native recruits and magenta triangles = immigrant recruits. The genetic change attributable to local adaptation (i.e., the net effect of breeder mortality and the recruitment of local-origin individuals) is represented by a grey dashed line, which differs from the total genetic change in the breeding population (solid black line) that additionally includes the contribution of immigrant recruitment.

Whereas first arrival has advanced over the long-term study, first laying hasn't (and the same holds true when we look at the averages). Still, 2025 is a fairly early year, as there are only 8 years with an earlier first egg versus 23 with a later first egg. #phenology #seabirds
