Organisms adapted to physiochemical stressors provide ideal systems to study evolutionary
mechanisms that drive adaptation and speciation. This review study focuses on livebearing …

In biogeography, vicariance and long‐distance dispersal are often characterised as
competing scenarios. However, they are related concepts, both relying on collective …

The fish subfamily Poeciliinae (sensu Parenti, 1981) is widely distributed across the Western
Hemisphere and a dominant component of the fish communities of Central America …

Regulating transcription allows organisms to respond to their environment, both within a
single generation (plasticity) and across generations (adaptation). We examined …

Annelore Kröger patiently prepared the voluminous graphic work. The partly coloured
drawings were produced by Monika Hänel. Arnhild Woltmann constantly provided ready …

Abstract The Nicaraguan Midas cichlid species complex is a natural experiment where fish
from a large source population from turbid and shallow great lakes very recently (< 20,000 …

The notorious plasticity of gene expression responses and the complexity of environmental
gradients complicate the identification of adaptive differences in gene regulation among …

Abstract The Amazon Molly (Poecilia formosa) reproduces by gynogenesis, a relatively rare
form of asexual reproduction where sperm is required to trigger embryogenesis, but male …

Abstract Poeciliids (Cyprinodontiformes: Poeciliidae), commonly known as livebearers, are
popular fishes in the aquarium trade (eg, guppies, mollies, swordtails) that are widely …

Abstract microRNAs (miRNAs) are post‐transcriptional regulators of gene expression and
can play an important role in modulating organismal development and physiology in …
