Open AccessGenetic architecture and lifetime dynamics of inbreeding depression in a wild mammal
Inbreeding depression is ubiquitous, but we still know little about its genetic architecture and precise effects in wild populations. Here, we combine long-term life-history data with 417 K imputed SNP genotyp...

Open AccessNo evidence for parental age effects on offspring leukocyte telomere length in free-living Soay sheep
In humans, the effect of paternal age at conception (PAC) on offspring leukocyte telomere length (LTL) is well established, with older fathers thought to pass on longer telomeres to their offspring in their sp...

Open AccessPhysiological proteins in resource-limited herbivores experiencing a population die-off
Nutrient availability is predicted to interact with herbivore population densities. Competition for low quality food at high density may reduce summer food intake, and in turn winter survival. Conversely, low ...

Open AccessInbreeding depression by environment interactions in a free-living mammal population
Experimental studies often find that inbreeding depression is more severe in harsh environments, but the few studies of in situ wild populations available to date rarely find strong support for this effect. We in...

The genetic basis of recessive self-colour pattern in a wild sheep population
Bridging the genotype–phenotype gap for traits of ecological and evolutionary importance in natural populations can provide a novel insight into the origin and maintenance of variation. Here, we identify the g...

Quantitative genetics of growth and cryptic evolution of body size in an island population
While evolution occurs when selection acts on a heritable trait, empirical studies of natural systems have frequently reported phenotypic stasis under these conditions. We performed quantitative genetic analys...

The effects of castration, sex ratio and population density on social segregation and habitat use in Soay sheep
We analysed 16 years of census data gathered on the island of Hirta (archipelago of St. Kilda) to investigate the effects of castration, population density, sex ratio, season and group type on habitat use and ...

Macroinvertebrate species and assemblages in the headwater streams of the River Tyne, northern England in relation to land cover and other environmental variables
The macroinvertebrate species and assemblages of headwater streams of the River Tyne catchment in northern England were classified and their relationship with environmental variables based on stream structure,...

Why large-scale climate indices seem to predict ecological processes better than local weather
Large-scale climatic indices such as the North Atlantic Oscillation1 are associated with population dynamics2, variation in demographic rates3 and values of phenotypic traits4,5 in many species. Paradoxically, th...

The running-water beetles (Coleoptera) of a river catchment in northern England
202 running-water sites in the catchment of the River Rede, a tributary of the River Tyne in northern England, were sampled for invertebrates in 1990. The distributions of water beetle species were investigate...
