Estimating the genetic basis of quantitative traits can be tricky for wild populations in natural
environments, as environmental variation frequently obscures the underlying evolutionary …

The female reproductive tract is where competition between the sperm of different males
takes place, aided and abetted by the female herself. Intense postcopulatory sexual …

Short-term evolutionary potential depends on the additive genetic variance in the
population. The additive variance is often measured as heritability, the fraction of the total …

Phenotype-based selective harvests, including trophy hunting, can have important
implications for sustainable wildlife management if they target heritable traits,,. Here we …

It is unclear when, where and how novel pathogens such as human immunodeficiency virus
(HIV), monkeypox and severe acute respiratory syndrome (SARS) will cross the barriers that …

An essential requirement to determine a population's potential for evolutionary change is to
quantify the amount of genetic variability expressed for traits under selection. Early …

Aim Vertebrates are declining worldwide, yet a comprehensive examination of the sources
of mortality is lacking. We conducted a global synthesis of terrestrial vertebrate cause …

Climate change is predicted to be most severe in northern regions and there has been much
interest in to what extent organisms can cope with these changes through phenotypic …

Immune function is likely to be a critical determinant of an organism's fitness, yet most
natural animal and plant populations exhibit tremendous genetic variation for immune traits …

Related individuals often have similar phenotypes, but this similarity may be due to the
effects of shared environments as much as to the effects of shared genes. We consider here …
