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.

Patterns of association between mothers and offspring and their outcomes in a polygynous ungulate

The paper examines mother-offspring association patterns in red deer, finding that prolonged association benefits female calves and yearlings but may reduce adult lifespan.

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.

Fitness costs of parasitism depend on fine-scale density and resource availability in a wild ungulate

This study examines how parasitism, density, and resource availability interact to affect survival and fecundity in wild red deer across their lifespan.

Parasite-mediated inbreeding depression in wild red deer

This study investigates parasite-mediated inbreeding depression in red deer, finding three pathways linking inbreeding to reduced fitness through parasitism.

Density-dependent network structuring within and across wild animal systems

The paper shows density increases network connectedness in wild animal populations, but effects saturate, with stronger spatial than social impacts.

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.

Population density drives increased parasitism via greater exposure and reduced resource availability in wild hosts

This study shows that higher host population density increases parasite counts through both greater exposure and reduced resource availability in red deer.

Evaluating regional heritability mapping methods for identifying QTLs in a wild population of Soay sheep

The paper evaluates regional heritability mapping methods to identify QTLs in Soay sheep, finding that some methods detect new trait-associated regions not found by GWAS.

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.

Investigating pedigree- and SNP-associated components of heritability in a wild population of Soay sheep

The paper applies a method to estimate heritability in a wild sheep population, finding that including an identity-by-descent GRM improves model fit for polygenic traits but not monogenic ones.

Selection, recombination and population history effects on runs of homozygosity (ROH) in wild red deer (Cervus elaphus)

The paper investigates factors shaping runs of homozygosity in red deer, finding population history has the greatest impact, with selection playing a minor role in some regions.

The impact of SNP density on quantitative genetic analyses of body size traits in a wild population of Soay sheep

This study examines how SNP density affects heritability estimates and QTL detection in Soay sheep body size traits using two SNP datasets.

Variants at RNF212 and RNF212B are associated with recombination rate variation in Soay sheep (Ovis aries).

The paper identifies genetic variants at RNF212 and RNF212B associated with recombination rate variation in Soay sheep using a larger dataset and animal models.

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.

RAD-sequencing for estimating GRM-based heritability in the wild: a case study in roe deer

This study uses RAD-sequencing to estimate GRM-based heritability in a wild roe deer population, showing robustness to genotyping errors and the impact of quality filters on heritability estimates.

A genomic region containing REC8 and RNF212B is associated with individual recombination rate variation in a wild population of red deer (Cervus elaphus)

The paper identifies a genomic region containing REC8 and RNF212B associated with recombination rate variation in red deer, showing heritability and conservation across mammals.

A high density linkage map reveals sexual dimorphism in recombination landscapes in red deer (Cervus elaphus)

The paper constructs a high density linkage map in red deer, revealing sex-specific differences in recombination rates near centromeres, with females showing higher rates in fission chromosomes.
