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.

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.

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.

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.
