The social environment is both an important agent of selection for most organisms, and an
emergent property of their interactions. As an aggregation of interactions among members of …

Background Long-term research of known individuals is critical for understanding the
demographic and evolutionary processes that influence natural populations. Current …

Animals in the wild die from a variety of different mortality sources, including predation,
disease, and starvation. Different mortality sources selectively remove individuals with …

The social environment may be a key mediator of selection that operates on animals. In
many cases, individuals may experience selection not only as a function of their phenotype …

While numerous studies have reported negative effects of urbanisation on birds, few have
examined the role of urban scale in influencing breeding success. Furthermore, many …

Both individual and group behavior can influence individual fitness, but multilevel selection
is rarely quantified on social behaviors. Social networks provide a unique opportunity to …

BACKGROUND Vole outbreaks have been extensively described, along with their impacts
on humans, particularly in agricultural areas. The use of rodenticides is a common legal …

Individuals often interact more closely with some members of the population (eg, offspring,
siblings, or group members) than they do with other individuals. This structuring of …

Social interactions with conspecifics can dramatically affect an individual's fitness. The
positive or negative consequences of interacting with social partners typically depend on the …

Spatial variation in natural selection is expected to shape phenotypic variation of wild
populations and drive their evolution. Although evidence of phenotypic divergence across …
