Climatic and topographic changes since the Miocene influenced the diversification and biogeography of the tent tortoise (Psammobates tentorius) species complex in Southern Africa
BACKGROUND: Climatic and topographic changes function as key drivers in shaping genetic structure and cladogenic radiation in many organisms. Southern …
Article scientifique
Multi-model seascape genomics identifies distinct environmental drivers of selection among sympatric marine species
BACKGROUND: As global change and anthropogenic pressures continue to increase, conservation and management increasingly needs to consider species' potential to …
Article scientifique
The roles of vicariance and isolation by distance in shaping biotic diversification across an ancient archipelago: evidence from a Seychelles caecilian amphibian
BACKGROUND: Island systems offer excellent opportunities for studying the evolutionary histories of species by virtue of their restricted size and …
Article scientifique
Phylogeography and genetic diversity of the copepod family Cyclopidae (Crustacea: Cyclopoida) from freshwater ecosystems of Southeast Nigeria
BACKGROUND: Copepods are key components of aquatic ecosystems and can help regulate the global carbon cycle. Much attention has been …
Article scientifique
Genetic diversity of a widespread annual killifish from coastal Tanzania
BACKGROUND: African annual killifishes (Nothobranchius spp.) are adapted to seasonally desiccating habitats (ephemeral pools), surviving dry periods as dormant eggs. …
Article scientifique
A genome-skimmed phylogeny of a widespread bryozoan family, Adeonidae
BACKGROUND: Understanding the phylogenetic relationships among species is one of the main goals of systematic biology. Simultaneously, credible phylogenetic hypotheses …
Article scientifique
Leaps and bounds: geographical and ecological distance constrained the colonisation of the Afrotemperate by Erica
BACKGROUND: The coincidence of long distance dispersal (LDD) and biome shift is assumed to be the result of a multifaceted …
Article scientifique
Nest defense in the face of cuckoldry: evolutionary rather than facultative adaptation to chronic paternity loss
BACKGROUND: Raising unrelated offspring is typically wasteful of parental resources and so individuals are expected to reduce or maintain low …
Article scientifique
Natriuretic peptides appeared after their receptors in vertebrates
BACKGROUND: In mammals, the natriuretic system contains three natriuretic peptides, NPPA, NPPB and NPPC, that bind to three transmembrane receptors, …
Article scientifique
Hooked on you: shape of attachment structures in cymothoid isopods reflects parasitic strategy
BACKGROUND: Parasite attachment structures are critical traits that influence effective host exploitation and survival. Morphology of attachment structures can reinforce …
Article scientifique
Small and genetically highly structured populations in a long-legged bee, Rediviva longimanus, as inferred by pooled RAD-seq
Adaptation to local host plants may impact a pollinator’s population genetic structure by reducing gene flow and driving population genetic …
Article scientifique
Interspecific information on predation risk affects nest site choice in a passerine bird
BACKGROUND: Breeding site choice constitutes an important part of the species niche. Nest predation affects breeding site choice, and has …
Article scientifique
Comparative phylogeography of parasitic Laelaps mites contribute new insights into the specialist-generalist variation hypothesis (SGVH)
The specialist-generalist variation hypothesis (SGVH) in parasites suggests that, due to patchiness in habitat (host availability), specialist species will show …
Article scientifique
The linear mitochondrial genome of the quarantine chytrid Synchytrium endobioticum; insights into the evolution and recent history of an obligate biotrophic plant pathogen
BACKGROUND: Chytridiomycota species (chytrids) belong to a basal lineage in the fungal kingdom. Inhabiting terrestrial and aquatic environments, most are …
Article scientifique
The inference of gray whale (Eschrichtius robustus) historical population attributes from whole-genome sequences
BACKGROUND: Commercial whaling caused extensive demographic declines in many great whale species, including gray whales that were extirpated from the …
Article scientifique
Population size may shape the accumulation of functional mutations following domestication
Population genetics theory predicts an important role of differences in the effective population size (N e ) among species on …
Article scientifique
Evolution of cytokinesis-related protein localization during the emergence of multicellularity in volvocine green algae
BACKGROUND: The volvocine lineage, containing unicellular Chlamydomonas reinhardtii and differentiated multicellular Volvox carteri, is a powerful model for comparative studies …
Article scientifique
Visual adaptation in Lake Victoria cichlid fishes: depth-related variation of color and scotopic opsins in species from sand/mud bottoms
BACKGROUND: For Lake Victoria cichlid species inhabiting rocky substrates with differing light regimes, it has been proposed that adaptation of …
Article scientifique
Does genetic structure reflect differences in non-breeding movements? A case study in small, highly mobile seabirds
BACKGROUND: In seabirds, the extent of population genetic and phylogeographic structure varies extensively among species. Genetic structure is lacking in …
Article scientifique
Female begging calls reflect nutritional need of nestlings in the hen harrier Circus cyaneus
BACKGROUND: Most birds exhibit bi-parental care with both sexes providing food for their young. Nestling signal food needs through begging. …
