Inverse relationship between genetic diversity and epigenetic complexity [PDF]

open access: yes, 2008
Early studies of molecular evolution revealed a correlation between genetic distance and time of species divergence. This observation provoked the molecular clock hypothesis and in turn the ‘Neutral Theory’, which however remains an ...

Reintroduction success of brook lamprey (Lampetra planeri) in a lowland stream in the Netherlands

open access: yesKnowledge and Management of Aquatic Ecosystems
Brook lamprey (Lampetra planeri) disappeared in half of its former range in the Netherlands. A reintroduction effort from 2014 to 2018 aimed at re-establishing a population in the Reusel Stream.

Amphibian chytridiomycosis : a review with focus on fungus-host interactions [PDF]

open access: yes, 2015
Amphibian declines and extinctions are emblematic for the current sixth mass extinction event. Infectious drivers of these declines include the recently emerged fungal pathogens Batrachochytrium dendrobatidis and Batrachochytrium salamandrivorans ...

The first complete mitochondrial DNA of the Chinese short-limbed skink (Ateuchosaurus chinensis Gray, 1845) determined by next-generation sequencing

open access: yesMitochondrial DNA. Part B. Resources, 2021
The complete mitochondrial DNA (mtDNA) for the Chinese short-limbed skink (Ateuchosaurus chinensis Gray, 1845) was described by using next-generation sequencing. The total length of mtDNA was 16,840 bp, which contained 13 PCGs (COI-III, ND1-6, ND4L, ATP6,

Genome elimination from the germline cells in diploid and triploid male water frogs Pelophylax esculentus

open access: yesFrontiers in Cell and Developmental Biology, 2022
Hybridogenesis is a hemiclonal reproductive strategy in diploid and triploid hybrids. Our study model is a frog P. esculentus (diploid RL and triploids RLL and RRL), a natural hybrid between P. lessonae (LL) and P. ridibundus (RR).

Odorant-binding proteins in canine anal sac glands indicate an evolutionarily conserved role in mammalian chemical communication

open access: yesBMC Ecology and Evolution, 2021
Background Chemical communication is an important aspect of the behavioural ecology of a wide range of mammals. In dogs and other carnivores, anal sac glands are thought to convey information to conspecifics by secreting a pallet of small volatile ...
