Biotic invasions can predominantly alter the dynamics, composition, functions, and structure
of natural ecosystems. Social insects, particularly ants, are among the most damaging …

A central role for sexual isolation in the formation of new species and establishment of
species boundaries has been noticed since Darwin and is frequently emphasized in the …

Gene exchange between species can influence ecological and evolutionary processes
ranging from population rescue to adaptive radiation. Genomic tools have provided new …

Reproductive interference (costly interspecific sexual interactions) is well‐understood to
promote divergence in mating‐relevant traits (ie reproductive character displacement: RCD) …

The coexistence of ecologically similar species might be counteracted by ecological drift and
demographic stochasticity, both of which erode local diversity. With niche differentiation …

Why many herbivorous insects are host plant specialists, with non‐negligible exceptions, is
a conundrum of evolutionary biology, especially because the host plants are not necessarily …

Reproductive interference is widespread, despite the theoretical expectation that it should
be eliminated by reproductive character displacement (RCD). A possible explanation is that …

Human-induced shifts in species' ranges can increase contact between closely related
species and lead to reproductive interference. In Australia, climate change and trade in …

The eradication of invasive exotic species is desirable but often infeasible. Here, we show
that male guppies are a potential biological agent for eradicating invasive mosquitofish …
