Open AccessGenomic characterization of the world’s longest selection experiment in mouse reveals the complexity of polygenic traits
Long-term selection experiments are a powerful tool to understand the genetic background of complex traits. The longest of such experiments has been conducted in the Research Institute for Farm Animal Biology ...

Open AccessPopulation and landscape genetic analysis of the Malayan sun bear Helarctos malayanus
Conservation genetics can provide data needed by conservation practitioners for their decisions regarding the management of vulnerable or endangered species, such as the sun bear Helarctos malayanus. Throughout i...

Open AccessAdaptive responses of animals to climate change are most likely insufficient
Biological responses to climate change have been widely documented across taxa and regions, but it remains unclear whether species are maintaining a good match between phenotype and environment, i.e. whether o...

Population genomics of the raccoon dog (Nyctereutes procyonoides) in Denmark: insights into invasion history and population development
The raccoon dog (Nyctereutes procyonoides) has a wide distribution in Europe and is a prominent example of a highly adaptable alien species. It has been recorded sporadically in Denmark since 1980 but observation...

High adaptive variability and virus-driven selection on major histocompatibility complex (MHC) genes in invasive wild rabbits in Australia
The rabbit haemorrhagic disease virus (RHDV) was imported into Australia in 1995 as a biocontrol agent to manage one of the most successful and devastating invasive species, the European rabbit (Oryctolagus cunic...

Open AccessWhole genome sequencing and methylome analysis of the wild guinea pig
DNA methylation is a heritable mechanism that acts in response to environmental changes, lifestyle and diseases by influencing gene expression in eukaryotes. Epigenetic studies of wild organisms are mandatory ...

Open AccessApplicability of major histocompatibility complex DRB1 alleles as markers to detect vertebrate hybridization: a case study from Iberian ibex × domestic goat in southern Spain
Hybridization between closely related wild and domestic species is of great concern because it can alter the evolutionary integrity of the affected populations. The high allelic variability of Major Histocompa...

Crossing the border? Structure of the red deer (Cervus elaphus) population from the Bavarian-Bohemian forest ecosystem
Anthropogenic impact such as overhunting and habitat fragmentation has reduced the total red deer population (Cervus elaphus) across Europe. In Germany remaining subpopulations are even confined to designated are...

Low genoty** error rates in non-invasively collected samples from roe deer of the Bavarian Forest National Park
Genetic wildlife monitoring is increasingly carried out on the basis of non-invasively collected samples, whereby the most commonly used DNA sources are skin appendages (hairs, feathers) and faeces. In order t...

Siberian tiger’s recent population bottleneck in the Russian Far East revealed by microsatellite markers
Because size reduced, or bottlenecked, populations are more prone to adverse events, the detection of genetic bottleneck signatures in wildlife species is highly relevant for conservation. Here we applied 11 m...

A fluorescence-based polymerase chain reaction-linked single-strand conformation polymorphism (F-PCR-SSCP) assay for the identification of Fasciola spp.
The present study aimed to establish a fluorescence-based polymerase chain reaction-linked single-strand conformation polymorphism (F-PCR-SSCP) assay for the identification of Fasciola spp. Based on the sequences...

Open AccessSuperconception in mammalian pregnancy can be detected and increases reproductive output per breeding season
The concept of superfetation, a second conception during pregnancy, has been controversial for a long time. In this paper we use an experimental approach to demonstrate that female European brown hares (Lepus eur...

Going west—invasion genetics of the alien raccoon dog Nyctereutes procynoides in Europe
The raccoon dog, a medium-sized carnivore, has long been recognised as a prominent example of an invasive alien species in Europe with a wide distribution, significant ecological impact and remarkable dynamics...

Characterization of 26 microsatellite marker loci in the fossa (Cryptoprocta ferox)
The fossa (Cryptoprocta ferox) is one of eight carnivore species endemic to Madagascar. This species lives in the forests of Madagascar and is classified as vulnerable by the IUCN due to the loss and fragmentatio...

Genetic structure of the Eurasian lynx population in north-eastern Poland and the Baltic states
We analyzed the genotypes of Eurasian lynx (Lynx lynx) from three populations in the westernmost part of the species main range. One population was situated at the distribution edge (NE Poland) and the two other ...

Cladogenesis of the European brown hare (Lepus europaeus Pallas, 1778)
A substantial portion of today’s biodiversity is attributed to the climatic oscillations of the Pleistocene Ice Ages. Gradual but dramatic climate changes were accompanied by expansion, contraction, and isolat...

Distribution of haplotypes and microsatellite alleles among Asian elephants (Elephas maximus) in Thailand
Habitat fragmentation often promotes increased inbreeding depression due to interrupted gene flow between populations. In this study, we demonstrate that Asian elephants most likely also suffer from outbreedin...

Structure of an otter (Lutra lutra) population in Germany - results of DNA and hormone analyses from faecal samples
Population size, one of the basic biological parameters is particularly difficult to estimate for nocturnal animals with cryptic life style and little individual distinctiveness like Eurasian otters (Lutra lutra)...

Characterization of reproductive activity in captive male Eurasian lynx (Lynx lynx)
This study characterizes the reproductive activity of male European lynx kept in Central Russia. Four captive adult males were subjected to an electroejaculation prior to (November), during (March) and after (...
