Phylogenetic analyses across 262 mammal sp. reveal that stronger male-biased sexual dimorphism is associated with lower mitochondrial genetic diversity, suggesting broader links between sexual selection, demography and population genetic structure: doi.org/10.1093/jeb/... de la Peña et al. 2026

New paper on accounting for phylogenetic uncertainty in comparative analyses: Weighted model-averaging is helpful, but usually not by much. Piccoli et al. @evolbiology.bsky.social, here: doi.org/10.1007/s116...

The decades-long habit of measuring animal sound frequencies in hertz biases #bioacoustics research. Part of the solution is very simple: do not measure animal sounds in Hz, measure them in logHz instead. New article @methodsinecoevol.bsky.social here: doi.org/10.1111/2041...

New Paper published 🎉🎉 👇👇👇

A waxbill with its red bill mottled black. This happens in breeding females, who mottle their red bill with juvenile-like black. Perhaps breeding females exploit others' innate responses towards juvenile bill colour. See the new article @asn-amnat.bsky.social here doi.org/10.1086/735832

📢New paper alert!📢 We found stronger senescence and environmental effects on female colour than on males in a mutually ornamented bird, the common waxbill. with S Guerra, C Romero-Diaz, P Silva, S Trigo, and @mostlywaxbills.bsky.social at Behavioral Ecology (1/5) academic.oup.com/beheco/artic...
