The likelihood to perform tool use during foraging is linked to personality traits in ants, suggesting an original interplay between consistent inter-individual variability and division of labor in social species.
Patterns of antibiotic use and the connectivity between wards are independently associated with the incidence of antimicrobial-resistant infections in hospital networks.
Moving patients between wards and prescribing high levels of antibiotics increases the spread of bacterial infections that are resistant to treatment in hospitals.

Calanoid copepods achieve efficient mate finding in turbulence through active swimming and turbulence advection, indicating that reproduction is not restricted to spatial and temporal windows of calm hydrodynamic conditions.
The presence of humans induces behavioral modifications in many large carnivore and ungulate species, restructuring spatiotemporal relationships between African predators and their prey.
High-resolution GPS data revealed a quadratic relationship between group size and movement, with vulturine guineafowl groups of intermediate size exhibiting the largest home-range size and greater variation in site use.
A systematic experimental comparison of prosocial behavior in eight corvid species reveals sex-specific effects of cooperative breeding and colonial nesting, thereby adding important new insights regarding the evolution of prosociality.
