PARASITE‐MEDIATED SELECTION AGAINST INBRED SOAY SHEEP IN A FREE‐LIVING ISLAND POPULATON
TLDR
It is shown that relatively inbred Soay sheep (Ovis aries) are more susceptible to parasitism by gastrointestinal nematodes, with interactions indicating greatest susceptibility among adult sheep at high population density, and it is suggested that parasite‐mediated selection acts to maintain genetic variation in this small island population by removing less heterozygous individuals.
Undesirable evolutionary consequences of trophy hunting
TLDR
Declines in mean breeding values for weight and horn size have declined significantly over time in an evolutionary response to sport hunting of bighorn trophy rams, resulting in the production of smaller-horned, lighter rams and fewer trophies.
Of glaciers and refugia: a decade of study sheds new light on the phylogeography of northwestern North America
TLDR
The emergent patterns from this review suggest the classic Beringian‐southern refugial paradigm for northwestern North American biota should be refined and highlighted to highlight the ecological and evolutionary consequences of colonization from multiple refugia.
SEX‐SPECIFIC GENETIC VARIANCE AND THE EVOLUTION OF SEXUAL DIMORPHISM: A SYSTEMATIC REVIEW OF CROSS‐SEX GENETIC CORRELATIONS
TLDR
It is demonstrated that the evolution of SD is typically genetically constrained and that sex‐specific selection coefficients may often be opposite in sign due to sub‐optimal levels of SD and validated the prediction of a negative correlation between rMF and SD.
Performance of Marker-Based Relatedness Estimators in Natural Populations of Outbred Vertebrates
TLDR
The five examples of vertebrate breeding systems suggest that due to the remarkably low variance in relatedness across the population, marker-based estimates may often have low power to address research questions of interest.

Abstract Meta‐analyses of published and unpublished correlations between phenotypic variation and two measures of genetic variation at microsatellite loci, multilocus heterozygosity (MLH) and mean
Mountain pine beetle host-range expansion threatens the boreal forest
TLDR
It is shown for the first time successful MPB attack in natural jack pine stands at the leading edge of the epidemic, and a panel of microsatellite loci optimized for both species to classify lodgepole pine, jack pine and their hybrids using simulated data is tested.
Birth weight and neonatal survival of harbour seal pups are positively correlated with genetic variation measured by microsatellites
TLDR
Mean d2 provides a better measure of individual genetic variability than heterozygosity for microsatellite data; and a convenient tool for assessing the effects of inbreeding and outbreeding in natural populations.
Age-dependent sexual selection in bighorn rams
TLDR
The results indicate that young or small rams possibly achieve mating success through alternative mating tactics that are less dependent on body and weapon size, such as coursing and blocking, and sexual selection is likely to have age–dependent effects on traits such as agility, body and horn size.
Overt and covert competition in a promiscuous mammal: the importance of weaponry and testes size to male reproductive success
TLDR
The Soay sheep mating system is characterized by male contests for mating opportunities and high female promiscuity and it is found that greater horn length, body size and good condition each independently influence a male' ability to monopolize receptive females.
