Revisiting the vanishing refuge model of diversification
Frontiers in Genetics, 2014 Much of the debate around speciation and historical biogeography has focused on the role of stabilizing selection on the physiological (abiotic) niche, emphasizing how isolation and vicariance, when associated with niche conservatism, may drive tropical ...

Selfish genetic elements and speciation [PDF]
Heredity, 1998 This review concerns the importance of selfish genetic elements (SGEs) in speciation. We assess the importance of medea genes, meiotic drive elements, transposable elements and the bacterium Wolbachia in the creation of postzygotic isolation. Although all of these elements can contribute to postzygotic isolation, their contribution will often disappear

Negative global-scale association between genetic diversity and speciation rates in mammals
Nature CommunicationsGenetic diversity is critical for species evolution and their adaptability to global changes, while speciation rate is critical for explaining large-scale patterns of species richness. Exploring correlates of variation in genetic diversity and speciation

Speciation Progress: A Case Study on the Bushcricket Poecilimon veluchianus. [PDF]
PLoS ONE, 2015 Different mechanisms such as selection or genetic drift permitted e.g. by geographical isolation can lead to differentiation of populations and could cause subsequent speciation.

Frontiers in Ecology and Evolution, 2021 Adaptation to different host plants is considered to be an important driver of the divergence and speciation of herbivorous insects. The application of molecular data and integrated taxonomic practices in recent years may contribute to our understanding ...

Frontiers in Plant Science, 2023 Habitat heterogeneity leads to genome-wide differentiation and morphological and ecological differentiation, which will progress along the speciation continuum, eventually leading to speciation.

The Genetics of Speciation by Reinforcement
PLoS Biology, 2004 Reinforcement occurs when natural selection strengthens behavioral discrimination to prevent costly interspecies matings, such as when matings produce sterile hybrids. This evolutionary process can complete speciation, thereby providing a direct link between Darwin's theory of natural selection and the origin of new species.

Ecological disruptive selection acting on quantitative loci can drive sympatric speciation
npj Systems Biology and ApplicationsThe process of speciation generates biodiversity. According to the null model of speciation, barriers between populations arise in allopatry, where, prior to biology, geography imposes barriers to gene flow.

Електроніка та інформаційні технологіїBackground. Genetic algorithms are used in various tasks and show advantages compared to other optimization methods, which may not always be applicable. However, there are cases when they can’t provide the best possible solution.

Nature Communications, 2019 Ecological speciation can proceed rapidly, but the origin of genetic variation facilitating it has remained elusive. Here, the authors show that secondary contact and introgression between deeply diverged lineages of stickleback fish facilitated rapid ...
