Independent origin of sperm heteromorphism in the Drosophilidae:

Abstract. Sperm heteromorphism, the production multiple discrete sperm types (or “morphs”), occurs in diverse animal and plant taxa. This phenomenon repres

Sexual conflict paper, mainly spiders!
'unless females are extremely rare relative to males, and/or male survival prospects are very slim, the highest quality males would avoid extreme investment and rather set out to look for additional females to mate with'
What about male quality? A model to predict male investment in a single female:

Our research on Liolaemus reveals that climbing species evolved specialized traits for clinging strength, yet terrestrial species maintain a "jack of all trades" morphology. Ecology drives evolution even in conserved body plans:

Individual-based model reveals sympatric allochronic divergence possible without ecological divergence. Male-male competition for females drives male activity timings towards an earlier activity timing niche:

Can the ghosts of environments past shape organismal phenotypes of future generations? In an experiment with clonal Daphnia lumholtzi, we reveal that predator-induced phenotypic changes in one generation can persist across several unexposed generations:

Color patterns help crayfish species hide, but they also may use them to communicate! Across 393 species, this research shows how colour patterns like stripes, spots, and bands evolve in freshwater crayfishes:

New work from @islandbirdproject.bsky.social using 3D bird models from 12 species across 3 archipelagos & mainland sites, we show that colourful plumage can be risky but not on islands!
