Parasites are thought to provide a selective force capable of promoting genetic variation in
natural populations. One rarely considered pathway for this action is via parasite‐mediated …

Sexual selection, through intra-male competition or female choice, is assumed to be a
source of strong and sustained directional selection in the wild 1 , 2 . In the presence of such …

Understanding the genetic architecture of phenotypic variation in natural populations is a
fundamental goal of evolutionary genetics. Wild Soay sheep (Ovis aries) have an inherited …

A functional immune system is important for survival in natural environments, where individuals
are frequently exposed to parasites. Yet strong immune responses may have fitness …

1. Reactive oxygen species, produced as a by-product of normal metabolism, can cause
intracellular damage and negatively impact on cell function. Such oxidative damage has been …

The estimation of quantitative genetic parameters in wild populations is generally limited by
the accuracy and completeness of the available pedigree information. Using relatedness at …

Males are predicted to compete for reproductive opportunities, with sexual selection driving
the evolution of large body size and weaponry through the advantage they confer for access …

Telomeres play a fundamental role in the maintenance of genomic integrity at a cellular level,
and average leukocyte telomere length ( LTL ) has been proposed as a biomarker of …

Hosts may mitigate the impact of parasites by two broad strategies: resistance, which limits
parasite burden, and tolerance, which limits the fitness or health cost of increasing parasite …

The degree to which changes in lifespan are coupled to changes in senescence in different
physiological systems and phenotypic traits is a central question in biogerontology. It is …
