Beggars can't be choosers: Competitive dominance and size‐dependent resource investment jointly constrain partner associations in a multispecies mutualism

Journal of Animal Ecology, EarlyView.
This study demonstrates that competition structures access to mutualistic partners that vary in value. Competitively dominant ants disproportionately invest in larger aphid colonies that produce more honeydew, restricting subordinate ants to smaller colonies.

Form, function, and evolution of worker–worker social carrying in ants

Insect Science, EarlyView.
Social carrying is a widespread ant recruitment behavior in which one worker physically transports another, usually during nest relocation. Across 62 species, phylogenetic analyses suggest that it originated as a stereotypical, coordinated behavior, with carrying posture largely conserved within subfamilies. Its occurrence across colony sizes indicates

Combined effects of the landscape and crop management on ant communities

Agricultural and Forest Entomology, EarlyView.
At small spatial scales, agricultural management acts as a stronger ecological filter than landscape context, significantly shaping ant community composition. Species richness and frequency did not differ among treatments, indicating the predominance of generalist species.

Loss, persistence and reversal of phenotypic traits

Biological Reviews, Volume 101, Issue 5, Page 2119-2133, October 2026.
ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...
