Reduced fertilization constitutes an important prezygotic reproductive barrier between two sibling species of the hybridizing Brachionus calyciflorus species complex
Brachionus calyciflorus is a species complex consisting of four recently described species. Although several lines of evidence support their species...

Demographic history and divergence of sibling grouse species inferred from whole genome sequencing reveal past effects of climate change
BackgroundThe boreal forest is one of the largest biomes on earth, supporting thousands of species. The global climate fluctuations in the...

Imprints of independent allopolyploid formations on patterns of gene expression in two sibling yarrow species (Achillea, Asteraceae)
BackgroundPolyploid species often originate recurrently. While this is well known, there is little information on the extent to which distinct...

Stage-dependent niche segregation: insights from a multi-dimensional approach of two sympatric sibling seabirds
Niche theory predicts that to reduce competition for the same resource, sympatric ecologically similar species should exploit divergent niches and...

Transcriptional responses are oriented towards different components of the rearing environment in two Drosophila sibling species
BackgroundThe chance to compare patterns of differential gene expression in related ecologically distinct species can be particularly fruitful to...

No evidence for long-range male sex pheromones in two malaria mosquitoes
Cues involved in mate seeking and recognition prevent hybridization and can be involved in speciation processes. In malaria mosquitoes, females of...
