This article reviews the history of gyrodactylid research focussing on the unique anatomy,
behaviour, ecology and evolution of the viviparous forms while identifying gaps in our …

Symbiotic bacteria often help their hosts acquire nutrients from their diet, showing trends of
co‐evolution and independent acquisition by hosts from the same trophic levels. While these …

Teleost fish provide some of the most intriguing examples of sexually dimorphic coloration,
which is often advantageous for only one of the sexes. Mapping studies demonstrated that …

The evolution of the placenta from a non-placental ancestor causes a shift of maternal
investment from pre-to post-fertilization, creating a venue for parent–offspring conflicts …

We constructed phylogenetic hypotheses for Mesoamerican Rhamdia, the only genus of
primary freshwater fish represented by sympatric species across Central America …

High genetic diversity is thought to characterize successful invasive species, as the potential
to adapt to new environments is enhanced and inbreeding is reduced. In the last century …

We investigated replicated ecological speciation in the livebearing fish Poecilia mexicana
and P. sulphuraria (Poeciliidae), which inhabit freshwater habitats and have also colonized …

To assess the historical biogeography of freshwater topminnows in the genus Poeciliopsis,
we examined sequence variation in two mitochondrial genes, cytochrome b (1140 bp) and …

Well‐studied model systems present ideal opportunities to understand the relative roles of
contemporary selection versus historical processes in determining population differentiation …

We inferred the phylogenetic relationships among members of the Poecilia sphenops
species complex to resolve the colonization process and radiation of this group in Central …
