Group size modulates kinship dynamics and selection on social traits

This study shows that group size affects kinship dynamics and age-related social behaviors in social mammals, with smaller groups promoting more extreme helping/harming behaviors, especially in younger individuals.

The Evolution of Democratic Peace in Animal Societies

This study applies evolutionary game theory to test the democratic peace hypothesis across animal societies, finding support for the idea that collective decision-making reduces intergroup conflict.

The evolution of parental effects when selection acts on fecundity versus viability

This study shows that viability selection promotes the evolution of parental effects in spatially structured populations, while fecundity selection does not.

Coping with strangers: how familiarity and active interactions shape group coordination in Corydoras aeneus

This study investigates how familiarity and active interactions influence group coordination in Corydoras aeneus, finding that nudges improve coordination but are less used by familiar individuals.

The Evolution of Early-Life Effects on Social Behaviour - Why Should Social Adversity Carry Over to the Future?

The paper models how early-life social experiences influence adult helping behaviors and shows natural selection favors positive social feedbacks that benefit future generations.

Maternal Effects and Parent-Offspring Conflict

The paper models how parent-offspring conflict influences the stability and resolution of maternal effects on offspring adaptation.
