No evidence sex-specific senescence varies with resource competition in Soay sheep

The study examines whether resource competition accelerates senescence in Soay sheep, finding no evidence of sex-specific variation in age-related decline under increased population density.

Environment dependent benefits of sociality in Soay sheep

The paper uses network analysis of 37 years of social association data in Soay sheep to show that social connections affect survival, with the importance of quantity versus quality depending on overwinter weather conditions.

Plasma insulin-like growth-factor 1 (IGF-1) concentrations predict early life-history traits in a wild mammal

This study shows that higher plasma IGF-1 levels in wild Soay sheep lambs correlate with better morphological traits and increased survival and reproductive success.

Local and global density have distinct and parasite-dependent effects on infection in wild sheep

The paper examines how local and global density affect parasite infection in wild sheep, finding distinct effects depending on age and parasite type.

Sex-specific effects of early-life adversity on adult fitness in a wild mammal

This study examines how early-life adversity affects adult fitness in wild Soay sheep, finding sex-specific differences in how environmental factors influence lifetime breeding success.

The genetic architecture of helminth-specific immune responses in a wild population of Soay sheep (Ovis aries)

This study identifies heritable genetic variation in immune traits of Soay sheep and finds large-effect genes outside the MHC region associated with antibody levels.
