Rapid Neural DNA Methylation Responses to Predation Stress in Trinidadian Guppies

open access: yesMolecular Ecology, Volume 34, Issue 10, May 2025.
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 ...

Tempo and mode of diversification of the red devil spiders (Araneae: Dysderidae) of the Canary Islands

open access: yesZoologica Scripta, Volume 54, Issue 3, Page 406-420, May 2025.
Abstract The study of adaptive radiations has shed light on our current understanding of evolution. However, previous studies examining the mode in which species diversified, how diversification rates varied, and how ecological specialisation affected these processes have found few different results across different taxa and geographic and ecological ...

Genetic status of selected fish taxa in relation to conservation of genetic and species diversity in the Victoria and Kyoga Lake basins [PDF]

open access: yes, 2000
Cichlids are known for their explosive radiation especially in the African Great Lakes marked with a high level of lake endemism. These fishes have been characterized mainly along trophic and habitat differences, by variation in morphological structures ...
