Admixture between old lineages facilitated contemporary ecological speciation in Lake Constance stickleback [PDF]
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 ...

Adaptive Divergence without Distinct Species Relationships Indicate Early Stage Ecological Speciation in Species of the Rhododendronpseudochrysanthum Complex Endemic to Taiwan [PDF]
The testing association of environmental variables with genetic and epigenetic variation could be crucial to deciphering the effects of environmental factors playing roles as selective drivers in ecological speciation.

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

Continuation of the genetic divergence of ecological speciation by spatial environmental heterogeneity in island endemic plants [PDF]
Divergent selection plays a critical role not only as a speciation driver but also in maintaining post-speciation divergence. In the absence of direct evidence, ancestral interspecific gene flow between incipient species can reflect ancient selective ...

Drosophila yakuba mayottensis, a new model for the study of incipient ecological speciation [PDF]
A full understanding of how ecological factors drive the fixation of genetic changes during speciation is obscured by the lack of appropriate models with clear natural history and powerful genetic toolkits.

Allopatric speciation is more prevalent than parapatric ecological divergence in a recent high-Andean diversification (Linochilus: Asteraceae) [PDF]
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.

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
