Cockroach social network position does not influence exploration tendency

This study finds no link between social network position and exploration tendency in cockroaches, and reports a single axis of social behavior variation.

Dolphin social phenotypes vary in response to food availability but not the North Atlantic Oscillation index

The paper shows bottlenose dolphins adjust social behavior based on food availability but not climate indices, with individual variation in social plasticity.

Direct and indirect phenotypic effects on sociability indicate potential to evolve

The study estimates phenotypic parameters for sociability in cockroaches, finding limited direct and indirect genetic effects, with sex-specific interaction coefficients suggesting potential for sexual conflict and dimorphism.

Social selection and the evolution of maladaptation

The paper develops a quantitative genetic model to identify conditions under which social selection leads to maladaptation, showing it occurs when social selection is strong and opposes individual-level selection.

Social selection is density dependent but makes little contribution to total selection in New Zealand giraffe weevils

The paper estimates social selection on body size in New Zealand giraffe weevils and finds it is density dependent but has little overall impact on total selection.

Territory acquisition mediates the influence of predators and climate on juvenile red squirrel survival

The paper examines how the timing of territory acquisition affects juvenile red squirrel survival and mediates the impacts of predators and climate.

Behavioral and physiological evidence that increasing group size ameliorates the impacts of social disturbance

The paper shows that larger group sizes reduce the negative impacts of social disturbance in Neolamprologus pulcher fish through behavioral and physiological evidence.

Orb-weaving spiders show a correlated syndrome of morphology and web structure in the wild

The paper examines the correlation between morphology and web structure in wild orb-weaving spiders, finding a syndrome linking body size to web traits and behavioral responses.

Collective behaviour is not robust to disturbance, yet parent and offspring colonies resemble each other in social spiders

The paper examines how collective foraging aggressiveness in social spider colonies responds to disturbances and whether parent-offspring colonies resemble each other in this behavior.

Multilevel selection in groups of groups

The paper examines multilevel selection in social spider colonies, finding that within-cluster competition and between-cluster selection depend on the number of rival colonies and colony aggressiveness.

Population differences in aggression are shaped by cyclone-induced selection

The paper shows that tropical cyclones drive the evolution of more aggressive spider societies by selecting for aggression in group-living spiders.

COLLECTIVE AGGRESSIVENESS LIMITS COLONY PERSISTENCE IN HIGH BUT NOT LOW ELEVATION SITES IN AMAZONIAN SOCIAL SPIDERS

The paper examines how collective aggressiveness in social spider colonies affects their persistence at different elevation sites in the Amazon, finding that less aggressive colonies persist better at high elevations.

Foundress Number, But Not Queen Size Or Boldness, Predicts Colony Life-History In Wild Paper Wasps

The paper examines colony life-history traits in two paper wasp species, finding that foundress number predicts productivity, while queen size and boldness do not.

Indirect genetic effects clarify how traits can evolve even when fitness does not

The paper shows how indirect genetic effects explain trait evolution without fitness increase by reconciling evolutionary theory with observed natural scenarios.

Social effects of territorial neighbours on the timing of spring breeding in North American red squirrels

The paper estimates indirect phenotypic and genetic effects of territorial neighbors on spring breeding timing in red squirrels, finding stronger social effects at high population densities.

Multilevel And Sex-Specific Selection On Competitive Traits In North American Red Squirrels

The paper quantifies multilevel and sex-specific natural selection on growth rate and birth date in red squirrels, showing stronger selection within social neighborhoods and litters, with females facing stronger growth rate selection.
