Organisms evolve in response to their natural environment. Consideration of natural
ecological parameters are thus of key importance for our understanding of an organism's …

Although many studies have examined quantitative trait variation across many species, only
a small number of genes and thereby molecular mechanisms have been discovered …

The hermaphroditic nematode Caenorhabditis elegans has been one of the primary model
systems in biology since the 1970s, but only within the last two decades has this nematode …

Males of Caenorhabditis elegans provide a crucial practical tool in the laboratory, but, as the
rarer and more finicky sex, have not enjoyed the same depth of research attention as …

Biparental sex is widespread in nature, yet costly relative to uniparental reproduction. It is
generally unclear why self-fertilizing or asexual lineages do not readily invade outcrossing …

Abstract Theory often predicts that host populations should evolve greater resistance when
parasites become abundant. Furthermore, that evolutionary response could ameliorate …

Abstract Theory on the evolution of niche width argues that resource heterogeneity selects
for niche breadth. For parasites, this theory predicts that parasite populations will evolve, or …

Abstract Theory predicts that organisms should diversify their offspring when faced with a
stressful environment. This prediction has received empirical support across diverse groups …

Although host and parasites are typically embedded in complex abiotic and biotic
environments our understanding of how environmental variation impacts on host-parasite …

The maintenance of males at intermediate frequencies is an important evolutionary problem.
Several species of Caenorhabditis nematodes have evolved a mating system in which …
