We compared 2080 songs from 72 individual black-capped and mountain chickadees in sympatry and allopatry. Sympatric mountain chickadee song differs markedly from all other populations, consistent with character displacement theory Taylor et al.: ow.ly/Clw850UgGZb

What does sexual size dimorphism (SSD) mean in terms of combat performance differences between the sexes? We explored this question looking at bite force in Anolis lizards in this new Journal of Evolutionary Biology paper: academic.oup.com/jeb/advance-ar…

Thanks to all the editors of this special issue Masahito Tsuboi Dr. Nicola Cook Thibault Latrille and Gaboriau Théo in Journal of Evolutionary Biology for inviting me to design the cover. It has been a first time and fun to mix one of my hobbies with my passion for science. I hope is the first of many more!

A great theme issue about the micro/macroevolution discussion in Journal of Evolutionary Biology, compiled by my colleague Masahito Tsuboi at @Biology_LU @lunduniver, Thibault Latrille and Gaboriau Théo! Nice to have contributed (a small part) to one of several interesting articles in this issue.

Experimental evolution of reduced resistance to toxic males under selection for faster development and early reproduction – connecting #lifehistory and #sexualconflict Verma et al: ow.ly/bB2U50UgGkM

Introgressed ancestry from popular #sportfish species the Smallmouth Bass has conferred phenotypic homogenization and potential constraints on body condition in native Neosho Bass in the Ozark Highlands: Gunn et al.: ow.ly/J74r50UgGyV

Research with satellite DNA in a contact zone between closely related lineages of frogs with different sex chromosomes reveals a cline in the number of autosomal clusters, indicating random assortment Souza et al. ow.ly/txQQ50Utpf8

Patterns of dietary convergence, rather than host phylogenetic history, seems to be an important driver of microbial community composition between several Sonoran cactophilic Drosophila species: DuBose et al. ow.ly/2veH50UtpmY

Postmating prezygotic isolation occurs at two levels of divergence in Drosophila recens and D. subquinaria: Dustman et al. ow.ly/RYv550UtptY

Testing the equivalency of human “predators” and deep neural networks in the detection of cryptic moths: Arias et al: ow.ly/METK50UtpCi

Infecting five fly host genotypes with isolates from distinct lineages of the obligate insect pathogenic fungus Entomophthora muscae shows - genetic makeup of both pathogen and host influence infectivity, confirming GxG interactions: Edwards et al: ow.ly/ikj550UtpJt

Using extensive data on external morphology of pygmy and marbled newts, we explored how allometry influences sexual size dimorphism. While sexes share a common allometric slope, species show significant divergences in slope directions: Ivanovic et al: ow.ly/TnPl50UtpU2
