Genetic and genomic data for African cichlids have accumulated over the past decades
along with an increase in data available on the composition and species richness of cichlid …

Cichlid fishes are the most species-rich group of all teleost fishes. Their diversity is centered
in the East African Great Lakes where more than 2,000 species evolved within the past 10 …

Striking trait polymorphisms are worthy of study in natural populations because they can
often shed light on processes of phenotypic divergence and specialization, adaptive …

We compared, through allozyme and cytochrome b sequence analyses, populations of
Bathygobius soporator from four localities on the Brazilian coast with those from the Oceanic …

Major environmental events that fragment populations among multiple island habitats have
potential to drive large‐scale episodes of speciation and adaptive radiation. A recent …

Developmental system drift is a likely mechanism for the origin of hybrid incompatibilities
between closely related species. We examine here the detailed mechanistic basis of hybrid …

The marine bryozoan Celleporella hyalina is a species complex composed of many highly
divergent and mostly allopatric genetic lineages that are reproductively isolated but share a …

The genetic structure of 10 populations (453 individuals) of stone loach (Barbatula barbatula
L.), a small bottom‐dwelling cyprinid fish, in the littoral zone of Lake Constance, central …

Stenotopic specialization to a fragmented habitat promotes the evolution of genetic structure.
It is not yet clear whether small-scale population structure generally translates into large …

Divergent selection acting on several different traits that cause multidimensional shifts are
supposed to promote speciation, but the outcome of this process is highly dependent on the …
