Bipolar disorder (BD) is one of the most heritable mental illnesses, but the elucidation of its
genetic basis has proven to be a very challenging endeavor. Genome-Wide Association …

ABSTRACT A forest species of millipede belonging to the Order Spirobolida found along the
eastern coast of southern Africa were tested for size assortative mating. The objectives …

Having recognized that variation around the population-level “Golden Mean” of labile traits
contains biologically meaningful information, behavioural ecologists have focused …

Variation in extra‐pair paternity (EPP) among individuals of the same population could result
from stochastic demography or from individual differences in mating strategies. Although the …

It is often claimed that pair bonds preferentially form between individuals that resemble one
another. Such assortative mating appears to be widespread throughout the animal kingdom …

Humans often mate with those resembling themselves, a phenomenon described as positive
assortative mating (PAM). The causes of this attract broad interest, but there is little …

Sexual selection is a fundamental evolutionary process but remains debated, particularly in
the complexity of polyandrous populations where females mate with multiple males. This …

Consistent individual differences in behavioral tendencies (animal personality) can affect
individual mate choice decisions. We asked whether personality traits affect male and …

Despite increasing evidence of the importance of repeatable among‐individual differences
in behaviour (animal personality) in ecology and evolution, little remains known about the …

Intraspecific variation in body size, both among populations and between sexes, is an
important factor influencing life-history strategies. This variation might be the response to …
