Behavioral sequences across multiple animal species in the wild share common structural features

The paper analyzes behavioral sequences in three wild mammal species and finds consistent structural patterns across all species, individuals, and behavioral states.

Accelerometer-based predictions of behaviour elucidate factors affecting the daily activity patterns of spotted hyenas

This study uses machine learning to analyze accelerometer data from spotted hyenas, revealing daily activity patterns influenced by social synchrony and individual behavior.

Taxonomic, genomic, and functional variation in the gut microbiomes of wild spotted hyenas across two decades of study

This study analyzes gut microbiome variation in wild spotted hyenas over 23 years, finding individualized and age-related microbiomes with novel genomic diversity.

Determinants of hyena participation in risky collective action

The paper investigates factors influencing hyena participation in risky cooperative fights with lions, finding social and contextual factors drive participation and benefit distribution.

Daily ranging and den usage patterns structure fission-fusion dynamics and social associations in spotted hyenas

This study examines how communal dens and daily movement patterns influence social interactions in spotted hyenas, revealing structured fission-fusion dynamics and social associations.

Measuring salivary cortisol in wild carnivores

This study develops a non-invasive method to measure salivary cortisol in wild spotted hyenas and finds a bimodal daily rhythm, social rank effects, and aggression-related cortisol changes.

Host phylogeny and host ecology structure the mammalian gut microbiota at different taxonomic scales

This study examines how host phylogeny and diet shape gut microbiota in 11 herbivore species, finding host taxonomy explains more variation than diet or season.

Toxoplasma gondii infections are associated with boldness towards lions in wild hyena hosts

A study finds that T. gondii infected hyena cubs approach lions more closely and have higher lion mortality rates, suggesting behavioral manipulation by the parasite.

Associations of early social experience with offspring DNA methylation and later life stress phenotype

The paper examines how early social experiences in spotted hyenas affect DNA methylation and stress phenotype later in life, finding associations between social connectedness and DNA methylation biomarkers near inflammation-related genes.

Rank-dependent social inheritance determines social network structure in a wild mammal population

The paper shows that social inheritance, based on maternal rank, shapes offspring relationships in wild spotted hyenas over six years, affecting their longevity.

Juvenile rank acquisition influences fitness independent of adult rank

This study shows that early life rank acquisition in spotted hyenas affects long-term fitness, independent of adult rank.
