The integration of phylogenetics, phylogeography and palaeoenvironmental studies is
providing major insights into the historical forces that have shaped the Earth's biomes. Yet …

A unisexual species is generally associated with polyploidy, and reproduced by a unisexual
reproduction mode, such as gynogenesis, hybridogenesis or parthenogenesis. Compared …

Phylogeography uses the spatial distribution of genealogical lineages to deduce the
influence of historical processes on the evolution of species, and can be informative in …

Approximately 99.9% of vertebrate species reproduce sexually. The exceptional 0.1%
reproduce via asexual or clonal means, which vary wildly and are fascinating in their own …

The persistence of sexual reproduction in the face of competition from asexual invaders is
more likely if asexual lineages are produced infrequently or have low fitness. The generation …

The study of genetic exchange resulting from natural hybridization, horizontal gene transfer,
and viral recombination has long been marked by controversy between researchers holding …

Theory predicts that sexual reproduction is difficult to maintain if asexuality is an option, yet
sex is very common. To understand why, it is important to pay attention to repeatably …

Abstract Development of continental aridity has been linked to late Cenozoic global cooling,
but the evidence is indirect, based on terrestrial loess deposits and eolian silt in marine …

Late Neogene aridification in the Southern Hemisphere caused contractions of mesic biota
to refugia, similar to the patterns established by glaciation in the Northern Hemisphere, but …

Studies of geographical distribution of parthenogenetic Darevskia armeniaca and its
parental species D. mixta and D. valentini can extend our knowledge in terms of their …
