Foraging environment determines the genetic architecture and evolutionary potential of trophic morphology in cichlid fishes.

open access: yesMolecular Ecology, 2016
Phenotypic plasticity allows organisms to change their phenotype in response to shifts in the environment. While a central topic in current discussions of evolutionary potential, a comprehensive understanding of the genetic underpinnings of plasticity is

Ancient Hybridisation Fuelled Diversification in Acropora Corals

open access: yesMolecular Ecology, EarlyView.
ABSTRACT Introgression is the infiltration or flow of genes from one species to another through hybridisation followed by backcrossing. This may lead to incorrect phylogenetic reconstruction or divergence‐time estimation. Acropora is a dominant genus of reef‐building corals; however, whether this group has an introgression history before their ...

Annotation of expressed sequence tags for the East African cichlid fish Astatotilapia burtoni and evolutionary analyses of cichlid ORFs

open access: yesBMC Genomics, 2008
Background The cichlid fishes in general, and the exceptionally diverse East African haplochromine cichlids in particular, are famous examples of adaptive radiation and explosive speciation.

Rapid and Parallel Adaptive Evolution of the Visual System of Neotropical Midas Cichlid Fishes

open access: yesMolecular biology and evolution, 2017
Midas cichlid fish are a Central American species flock containing 13 described species that has been dated to only a few thousand years old, a historical timescale infrequently associated with speciation.

Rapid Neural DNA Methylation Responses to Predation Stress in Trinidadian Guppies

open access: yesMolecular Ecology, EarlyView.
ABSTRACT DNA methylation (DNAm) is a well‐studied epigenetic mechanism implicated in environmentally induced phenotypes and phenotypic plasticity. However, few studies investigate the timescale of DNAm shifts. Thus, it is uncertain whether DNAm can change on timescales relevant for rapid phenotypic shifts, such as during the expression of short‐term ...

Adaptive sequence evolution in a color gene involved in the formation of the characteristic egg-dummies of male haplochromine cichlid fishes

open access: yesBMC Biology, 2007
Background The exceptionally diverse species flocks of cichlid fishes in East Africa are prime examples of parallel adaptive radiations. About 80% of East Africa's more than 1 800 endemic cichlid species, and all species of the flocks of Lakes Victoria ...

The onset of ecological diversification 50 years after colonization of a crater lake by haplochromine cichlid fishes

open access: yesProceedings of the Royal Society B: Biological Sciences, 2018
Adaptive radiation research typically relies on the study of evolution in retrospective, leaving the predictive value of the concept hard to evaluate.

The effect of size on mate selection, fecundity and survival in Culex pipiens mosquitoes

open access: yesPhysiological Entomology, EarlyView.
Larval diet affects male and female adult size, female fecundity and female survival. Large non‐blood–fed females lived longer than small non‐blood–fed females. Mate size did not influence mating rate (insemination status). Even though larger females are more fit, males mated equally to large and small females when given the option. Blood feeding has a
