Postcopulatory sexual selection (PCSS), comprised of sperm competition and cryptic female
choice, has emerged as a widespread evolutionary force among polyandrous animals …

Sperm production and allocation strategies have been a central concern of sperm
competition research for the past 50 years. But during the 'sexual cascade'there may be …

Sperm competition favors large, costly ejaculates, and theory predicts the evolution of
allocation strategies that enable males to plastically tailor ejaculate expenditure to sperm …

Small RNAs (sRNAs) regulate genes in plants and animals. Here, we show that population-
wide differences in color patterns in snapdragon flowers are caused by an inverted …

It is increasingly clear that social environments have profound impacts on the life histories of
'non-social'animals. However, it is not yet well known how species with varying degrees of …

Social isolation strongly modulates behavior across the animal kingdom. We utilized the fruit
fly Drosophila melanogaster to study social isolation-driven changes in animal behavior and …

Animals respond to changes in the environment which affect their internal state by adapting
their behaviors. Social isolation is a form of passive environmental stressor that alters animal …

Social environments have been shown to have multiple effects on individual immune
responses. For example, increased social contact might signal greater infection risk and …

Seminal fluid proteins (SFPs) are crucial mediators of sexual selection and sexual conflict.
Recent studies have chiefly focused on environmentally induced plasticity as one source of …

A considerable body of evidence supports the prediction that males should increase their
expenditure on the ejaculate in response to sperm competition risk. The prediction that they …
