Maternal Care Leads to the Evolution of Long, Slow Lives

This paper models how maternal care influences the evolution of long, slow life histories in mammals.

Animal Emotions and Consciousness: Researchers' Perceptions, Biases, and Prospects for Future Progress

This paper surveys animal behavior researchers to assess perceptions on animal emotions and consciousness, finding broad ascription to various taxa and optimism about future scientific progress.

Genetically Identical Mice Express Alternative Reproductive Tactics Depending on Social Conditions in the Field

The study shows genetically identical mice adopt different reproductive tactics based on social conditions, with territorial males having higher survival and mating success.

Five decades of data yield no support for adaptive biasing of offspring sex ratio in wild baboons (Papio cynocephalus)

The paper tests four hypotheses about adaptive sex ratio bias in wild baboons using a large dataset and finds no support for adaptive biasing of offspring sex ratios.

Female behavior drives the formation of distinct social structures in C57BL/6J versus wild-derived outbred mice in field enclosures

The paper compares social structures formed by C57BL/6J and wild-derived mice in field enclosures, finding distinct differences in female behavior and social network density.

Beyond orphaned infants: novel effects of maternal death in wild primates

The paper examines the effects of maternal death on offspring fitness in wild primates, finding reduced survival before maternal death and intergenerational fitness impacts in three species.

Threshold assessment, categorical perception, and the evolution of reliable signaling

The paper investigates how threshold responses in receivers affect the reliability of assessment signals and shows that receiver threshold variation can rescue reliable signaling.

Comparing proportional and ordinal dominance ranks reveals multiple competitive landscapes in an animal society

This study compares ordinal and proportional dominance rank metrics to predict 20 traits in wild baboons, finding sex-specific differences in how competition shapes outcomes.

Intergenerational effects of early adversity on survival in wild baboons

The paper shows that early adversity in wild baboon mothers reduces offspring survival, independent of the offspring's own adversity, through parental effects.
