Science, 2007 Like the formation of animal species, plant speciation is characterized by the evolution of barriers to genetic exchange between previously interbreeding populations. Prezygotic barriers, which impede mating or fertilization between species, typically contribute more to total reproductive isolation in plants than do postzygotic barriers, in which ...

Mechanisms of Speciation [PDF]
International Journal of Evolutionary Biology, 2012 “Speciation” was largely “speculation” two decades ago, at least with respect to a detailed and comprehensive mechanistic understanding of the origin of new species. Despite elegant classical work examining the genetic basis of interspecific differences and reproductive isolation and complementary studies of the ecological factors that can contribute ...

eLife, 2020 Zinc and copper are involved in neuronal differentiation and synaptic plasticity but the molecular mechanisms behind these processes are still elusive due in part to the difficulty of imaging trace metals together with proteins at the synaptic level.

Genomics of plant speciation [PDF]
, 2023 Studies of plants have been instrumental for revealing how new species originate. For several decades, botanical research has complemented and, in some cases, challenged concepts on speciation developed via the study of other organisms while also ...

Invasive species and biodiversity crises: testing the link in the late devonian. [PDF]
PLoS ONE, 2010 During the Late Devonian Biodiversity Crisis, the primary driver of biodiversity decline was the dramatic reduction in speciation rates, not elevated extinction rates; however, the causes of speciation decline have been previously unstudied.

A screen for recessive speciation genes expressed in the gametes of F1 hybrid yeast [PDF]
, 2007 Diploid hybrids of Saccharomyces cerevisiae and its closest relative, Saccharomyces paradoxus, are viable, but the sexual gametes they produce are not.

Ability of Current Phylogenetic Clustering to Detect Speciation History
Frontiers in Ecology and Evolution, 2021 Phylogenetic diversity aims to quantify the evolutionary relatedness among the species comprising a community, using the phylogenetic tree as the metric of the evolutionary relationships.
