Selection and demography drive range-wide patterns of MHC-DRB variation in mule deer
Standing genetic variation is important especially in immune response-related genes because of threats to wild populations like the emergence of novel pathogens. Genetic variation at the major histocompatibili... (Source: BMC Evolutionary Biology)

Divergent and non-parallel evolution of MHC IIB in the Neotropical Midas cichlid species complex
Ecological diversification is the result of divergent natural selection by contrasting habitat characteristics that favours the evolution of distinct phenotypes. This process can happen in sympatry and in allo... (Source: BMC Evolutionary Biology)

Phenotypic differentiation and diversifying selection in populations of Eruca sativa along an aridity gradient
The aridity gradient in the eastern Mediterranean offers an opportunity to investigate intra-specific genetic differentiation and local adaptation in plant populations. Here we used genetic (FST) and quantitative... (Source: BMC Evolutionary Biology)

Widely used, short 16S rRNA mitochondrial gene fragments yield poor and erratic results in phylogenetic estimation and species delimitation of amphibians
The 16S mitochondrial rRNA gene is the most widely sequenced molecular marker in amphibian systematic studies, making it comparable to the universal CO1 barcode that is more commonly used in other animal groups. ... (Source: BMC Evolutionary Biology)

Investigating the interaction between inter-locus and intra-locus sexual conflict using hemiclonal analysis in Drosophila melanogaster
Divergence in the evolutionary interests of males and females leads to sexual conflict. Traditionally, sexual conflict has been classified into two types: inter-locus sexual conflict (IeSC) and intra-locus sex... (Source: BMC Evolutionary Biology)

Multi-modal locomotor costs favor smaller males in a sexually dimorphic leaf-mimicking insect
In most arthropods, adult females are larger than males, and male competition is a race to quickly locate and mate with scattered females (scramble competition polygyny). Variation in body size among males may... (Source: BMC Evolutionary Biology)

Remnants of horizontal transfers of Wolbachia genes in a Wolbachia-free woodwasp
Wolbachia is a bacterial endosymbiont of many arthropod and nematode species. Due to its capacity to alter host biology, Wolbachia plays an important role in arthropod and nematode ecology and evolution. Sirex no... (Source: BMC Evolutionary Biology)

Variation in intraspecific demography drives localised concordance but species-wide discordance in response to past climatic change
Understanding how species biology may facilitate resilience to climate change remains a critical factor in detecting and protecting species at risk of extinction. Many studies have focused on the role of parti... (Source: BMC Evolutionary Biology)

High morphological disparity in a bizarre Paleocene fauna of predatory freshwater reptiles
The consequences of the K-Pg mass extinction are reflected across present biodiversity, but many faunas that appeared immediately after the extinction event were very different from current ones. Choristodera ... (Source: BMC Evolutionary Biology)

Symbiont-conferred immunity interacts with effects of parasitoid genotype and intraguild predation to affect aphid immunity in a clone-specific fashion
Host-parasite interactions represent complex co-evolving systems in which genetic and associated phenotypic variation within a species can significantly affect selective pressures on traits, such as host immun... (Source: BMC Evolutionary Biology)

Phylogeny of Merlin ’s grass (Isoetaceae): revealing an “Amborella syndrome” and the importance of geographic distribution for understanding current and historical diversity
Merlin ’s grass (Isoetes, Isoetaceae, Lycopsida), is the extant remnant of the isoetalean wood-producing lycopsids that originated during the Paleozoic, possibly in aquatic or boggy habitats. Modern day species ar... (Source: BMC Evolutionary Biology)
