Genomic resequencing provides new insights into ecological diversification of four Saccharina Japonica varieties [PDF]

BMC Genomics
Background  Saccharina japonica is a commercially and ecologically important seaweed and shows rapid ecological speciation. This kelp represents an excellent model for understanding the process and genetic mechanism of diversification and speciation of ...

Divergent selection drives genetic differentiation in an R2R3-MYB transcription factor that contributes to incipient speciation in Mimulus aurantiacus. [PDF]

PLoS Genetics, 2013
Identifying the molecular genetic basis of traits contributing to speciation is of crucial importance for understanding the ecological and evolutionary mechanisms that generate biodiversity. Despite several examples describing putative "speciation genes,"

Negative global-scale association between genetic diversity and speciation rates in mammals

Nature Communications
Genetic 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

Mating system and speciation I: Accumulation of genetic incompatibilities in allopatry.

PLoS Genetics, 2022
Self-fertilisation is widespread among hermaphroditic species across the tree of life. Selfing has many consequences on the genetic diversity and the evolutionary dynamics of populations, which may in turn affect macroevolutionary processes such as ...

Incipient Sympatric Speciation and Evolution of Soil Bacteria Revealed by Metagenomic and Structured Non-Coding RNAs Analysis

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.

Neurospora from natural populations: Population genomics insights into the Life history of a model microbial Eukaryote [PDF]

, 2020
The ascomycete filamentous fungus Neurospora crassa played a historic role in experimental biology and became a model system for genetic research. Stimulated by a systematic effort to collect wild strains initiated by Stanford geneticist David Perkins ...

Incipient speciation between host-plant strains in the fall armyworm

BMC Ecology and Evolution, 2022
Background Recent advancement in speciation biology proposes that genetic differentiation across the whole genome (genomic differentiation, GD) may occur at the beginning of a speciation process and that GD itself may accelerate the rate of speciation ...

Multilocus phylogeography and ecological niche modeling suggest speciation with gene flow between the two Bamboo Partridges

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

Accumulation of gene copy number variations during the early phase of free‐spawning abalone speciation

Ecology and Evolution, 2023
The genetic basis of speciation in free‐spawning marine invertebrates is poorly understood. Although gene copy number variations (GCNVs) and nucleotide variations possibly trigger the speciation of these organisms, empirical evidence for such a ...

Varying Intensities of Introgression Obscure Incipient Venom-Associated Speciation in the Timber Rattlesnake (Crotalus horridus)

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
