Existing and emerging pathogens pose unusual challenges for conservation because of
their potential to drive rapid changes in the numerical abundance and genetic composition …

Coinfections by multiple parasites predominate in the wild. Interactions between parasites
can be antagonistic, neutral, or facilitative, and they can have significant implications for …

In theory, parasites can create time‐lagged, frequency‐dependent selection in their hosts,
resulting in oscillatory gene‐frequency dynamics in both the host and the parasite (the Red …

The geographic mosaic theory of coevolution is predicated on structured populations of
interacting species where gene flow and the force of selection can vary among populations …

Sexual populations should be vulnerable to invasion and replacement by ecologically
similar asexual females because asexual lineages have higher per capita growth rates …

Parasites, including macroparasites, protists, fungi, bacteria and viruses, can impose a
heavy burden upon host animals. However, hosts are not without defences. One aspect of …

The maintenance of sexual reproduction in natural populations is a pressing question for
evolutionary biologists [1, 2]. Under the" Red Queen" hypothesis, coevolving parasites …

Sexual reproduction is both extremely costly and widespread relative to asexual
reproduction, meaning that it must also confer profound advantages in order to persist. One …

Curtis M. Lively ost eukaryotic organisms re-produce by cross-fertilization, at least during
some part of their life cycle. Given the costs incurred by cross-fertilization, this pattern …

The maintenance of sexual reproduction by natural selection poses a paradox for
evolutionary biology. Assuming “all else equal,” a sexual lineage producing both males and …
