Do relaxed selection and habitat temperature facilitate biased mitogenomic introgression in a narrowly endemic fish? [PDF]

Ecol Evol, 2016
In this study, we used a combination of genetic and environmental data, to examine mitochondrial introgression in the narrowly endemic and trophically polymorphic cichlid, Herichthys minckleyi. Using extensive mitochondrial sequencing and 6220 nuclear single nucleotide polymorphisms, we show that mitochondrial introgression into H.

Predator-induced changes of female mating preferences: innate and experiential effects. [PDF]

BMC Evol Biol, 2011
Background: In many species males face a higher predation risk than females because males display elaborate traits that evolved under sexual selection, which may attract not only females but also predators. Females are, therefore, predicted to avoid such
