In situ measurements of muscular twitch speed reveal one of the fastest vertebrate limb muscles on record, which evolved in association with extravagant courtship displays that include rapid limb movements.

Social information is a process encompassing information acquisition, application and exploitation that is constrained by an individual’s social, behavioural and demographic phenotype.

Dynamic successive blooms of clades of planktonic marine bacteria that can be observed during blooms of marine algae follow discernible patterns, part of which might be explained by substrate-induced forcing.
Building on previous work (Momeni et al., 2013), it is shown that recognizing the hierarchical organization of biological systems resolves the ongoing controversy on pro-cooperation mechanisms.

A computational model shows that natural selection can cause populations to evolve a distinctive population-level phenotype: the ability to transition between collective states in response to the environment.

A mathematical model predicts the precise conditions for natural selection to favor the evolution of non-reproductive workers in insect colonies with haplodiploid genetics.

Maneuverability is thought to be limited by either intrinsic constraints or physiological capacity, and automated tracking of flying hummingbirds reveals that muscle capacity explains much of the variation in their flight trajectories.
