Fundamental to understanding how biodiversity arises and adapts is whether evolution is
predictable in the face of stochastic genetic and demographic factors. Here we show rapid …

The formation of species in the absence of geographic barriers (ie sympatric speciation)
remains one of the most controversial topics in evolutionary biology. While theoretical …

Determining the genetic bases of adaptations and their roles in speciation is a prominent
issue in evolutionary biology. Cichlid fish species flocks are a prime example of recent rapid …

The identification of thousands of variants across the genomes and their accurate
genotyping are crucial for estimating the genetic parameters needed to address a host of …

Explaining why some lineages diversify while others do not and how are key objectives in
evolutionary biology. Young radiations of closely related species derived from the same …

Gut bacterial communities are now known to influence a range of fitness related aspects of
organisms. But how different the microbial community is in closely related species, and if …

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 …

Meristic traits are often treated as distinct phenotypes that can be used to differentiate and
delineate recently diverged species. For instance, the number of lateral line scales and …

A common pattern of adaptive diversification in freshwater fishes is the repeated evolution of
elongated open water (limnetic) species and high‐bodied shore (benthic) species from …

Abstract Background Central American crater lake cichlid fish of the Midas species complex
(Amphilophus spp.) are a model system for sympatric speciation and fast ecological …
