Seven Questions on the Chemical Ecology and Neurogenetics of Resource-Mediated Speciation
Frontiers in Ecology and Evolution, 2021 Adaptation to different environments can result in reproductive isolation between populations and the formation of new species. Food resources are among the most important environmental factors shaping local adaptation.

Biology, 2022 Soil bacteria respond rapidly to changes in new environmental conditions. For adaptation to the new environment, they could mutate their genome, which impacts the alternation of the functional and regulatory landscape.

Molecular biology and evolution, 2023 When challenged by similar environmental conditions, phylogenetically distant taxa often independently evolve similar traits (convergent evolution).

Transgressive segregation, adaptation and speciation [PDF]
Heredity, 1999 The production of extreme or 'transgressive' phenotypes in segregating hybrid populations has been speculated to contribute to niche divergence of hybrid lineages. Here, we assess the frequency of transgressive segregation in hybrid populations, describe its genetic basis and discuss the factors that best predict its occurrence.

The role of divergent ecological adaptation during allopatric speciation in vertebrates
Science, 2022 After decades of debate, biologists today largely agree that most speciation events require an allopatric phase (that is, geographic separation), but the role of adaptive ecological divergence during this critical period is still unknown.

Molecular biology and evolution, 2022 Incorrect species delimitation will lead to inappropriate conservation decisions, especially for threatened species. The takin (Budorcas taxicolor) is a large artiodactyl endemic to the Himalayan–Hengduan–Qinling Mountains and is well known for its ...

Adaptive speciation theory: a conceptual review [PDF]
Behavioral Ecology and Sociobiology, 2011 Speciation-the origin of new species-is the source of the diversity of life. A theory of speciation is essential to link poorly understood macro-evolutionary processes, such as the origin of biodiversity and adaptive radiation, to well understood micro-evolutionary processes, such as allele frequency change due to natural or sexual selection.

Thermal adaptation and ecological speciation [PDF]
Molecular Ecology, 2011 AbstractEcological speciation is defined as the emergence of reproductive isolation as a direct or indirect consequence of divergent ecological adaptation. Several empirical examples of ecological speciation have been reported in the literature which very often involve adaptation to biotic resources. In this review, we investigate whether adaptation to
