Allopatric speciation is more prevalent than parapatric ecological divergence in a recent high-Andean diversification (Linochilus: Asteraceae) [PDF]
PeerJ, 2023 Elucidating how species accumulate in diversity hotspots is an ongoing debate in evolutionary biology. The páramo, in the Northern Andes, has remarkably high indices of plant diversity, endemicity, and diversification rates.

Avian Research, 2021 Background Understanding how species diversify is a long-standing question in biology. The allopatric speciation model is a classic hypothesis to explain the speciation process. This model supposes that there is no gene flow during the divergence process

Toxins, 2021 Ecologically divergent selection can lead to the evolution of reproductive isolation through the process of ecological speciation, but the balance of responsible evolutionary forces is often obscured by an inadequate assessment of demographic history and

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.

Functional diversification within a predatory species flock. [PDF]
PLoS ONE, 2013 Ecological speciation is well-known from adaptive radiations in cichlid fishes inhabiting lentic ecosystems throughout the African rift valley and Central America.

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.

Little ecological divergence associated with speciation in two African rain forest tree genera
BMC Evolutionary Biology, 2011 Background The tropical rain forests (TRF) of Africa are the second largest block of this biome after the Amazon and exhibit high levels of plant endemism and diversity. Two main hypotheses have been advanced to explain speciation processes that have led

Genomics of Rapid Incipient Speciation in Sympatric Threespine Stickleback. [PDF]
PLoS Genetics, 2016 Ecological speciation is the process by which reproductively isolated populations emerge as a consequence of divergent natural or ecologically-mediated sexual selection.

Ecological niche divergence associated with species and populations differentiation in Erythrophleum (Fabaceae, Caesalpinioideae) [PDF]
Plant Ecology and Evolution, 2019 Background and aims – The isolation of populations inside forest refugia during past climate changes has widely been hypothesized as a major driver of tropical plant diversity.

Ecological speciation in the tropics: Insights from comparative genetic studies in Amazonia
Frontiers in Genetics, 2015 Evolution creates and sustains biodiversity via adaptive changes in ecologically relevant traits. Ecologically mediated selection contributes to genetic divergence both in the presence or absence of geographic isolation between populations, and is ...
