Ecologically mediated selection against hybrids, caused by hybrid phenotypes fitting poorly
into available niches, is typically viewed as distinct from selection caused by epistatic …

ABSTRACT A major goal of evolutionary science is to understand how biological diversity is
generated and altered. Despite considerable advances, we still have limited insight into how …

Natural microbial ecosystems harbor substantial diversity of competing species. Explaining
such diversity is challenging, because in classic theories it is extremely infeasible for a large …

Invasive species can be powerful models for studying contemporary evolution in natural
environments. As invading organisms often encounter new habitats during colonization, they …

Human habitat disturbance affects both species diversity and intraspecific genetic diversity,
leading to correlations between these two components of biodiversity (termed species …

Unifying ecosystem ecology and evolutionary biology promises a more complete
understanding of the processes that link different levels of biological organization across …

Identifying traits that underlie variation in individual performance of consumers (ie, trait
utility) can help reveal the ecological causes of population divergence and the subsequent …

Differentiation of foraging traits among predator populations may help explain observed
variation in the structure of prey communities. However, few studies have investigated the …

Parasites can shape the structure and function of ecosystems by influencing both the density
and traits of their hosts. Such changes in ecosystems are particularly likely when the host is …

Evidence that organisms evolve rapidly enough to alter ecological dynamics necessitates
investigation of the reciprocal links between ecology and evolution. Data that link genotype …
