Castration is a response to the tradeoff between consumption and longevity faced by
parasites. Common parasitic castrators include larval trematodes in snails, and isopod and …

Energy balance is a fundamental requirement of stress adaptation and tolerance. We
explore the links between metabolism, energy balance and stress tolerance using aquatic …

Bioenergetic models, and specifically dynamic energy budget (DEB) theory, are gathering a
great deal of interest as a tool to predict the effects of realistically variable exposure to …

Sex allocation is a crucial life-history parameter in all sexual organisms. Over the last
decades a body of evolutionary theory, sex allocation theory, was developed, which has …

Although vertical transmission from parents to offspring through seeds is an important fitness
component of many plant viruses, very little is known about the factors affecting this process …

Epidemiologists increasingly realize that species interactions (eg selective predation) can
determine when epidemics start and end. We hypothesize here that resource quality can …

The term “hormesis” is used to describe dose–response relationships where the response is
reversed between low and high doses of a stressor (generally, stimulation at low doses and …

Parasites steal resources that a host would otherwise direct toward its own growth and
reproduction. We use this fundamental notion to explain resource-dependent virulence in a …

The “dilution effect” concept in disease ecology offers the intriguing possibility that clever
manipulation of less competent hosts could reduce disease prevalence in populations of …

Predators could reduce disease prevalence in prey populations by culling infected hosts
and reducing host density. However, recently observed positive correlations between …
