Multiple invasions of a generalist herbivore—Secondary contact between two divergent lineages of Nezara viridula Linnaeus in Australia

Evolutionary Applications, 2020
The presence of distinct evolutionary lineages within herbivorous pest insect taxa requires close attention. Scientific understanding, biosecurity planning and practice, and pest management decision‐making each suffer when such situations remain poorly ...

Directional gene flow and ecological separation in Yersinia enterocolitica [PDF]

, 2015
Yersinia enterocolitica is a common cause of food-borne gastroenteritis worldwide. Recent work defining the phylogeny of the genus Yersinia subdivided Y. enterocolitica into six distinct phylogroups. Here, we provide detailed analyses of the evolutionary

Gene flow contributes to diversification of the major fungal pathogen Candida albicans

Nature Communications, 2018
Elucidating population structure and levels of genetic diversity and recombination is necessary to understand the evolution and adaptation of species. Candida albicans is the second most frequent agent of human fungal infections worldwide, causing high ...

Local thermal adaptation and limited gene flow constrain future climate responses of a marine ecosystem engineer

Evolutionary Applications, 2020
Rising ocean temperatures and extreme temperature events have precipitated declines and local extinctions in many marine species globally, but patterns of loss are often uneven across species ranges for reasons that are poorly understood.

Speciation with gene flow via cycles of isolation and migration: insights from multiple mangrove taxa

bioRxiv, 2018
Allopatric speciation requiring an unbroken period of geographical isolation has been the standard model of neo-Darwinism. While doubts have been repeatedly raised, strict allopatry without any gene flow remains a plausible mechanism in most cases.

Testing hypotheses for morphological differences among populations of Miconia sellowiana (Melastomataceae) in southern Brazil - doi: 10.4025/actascibiolsci.v34i1.7580

Acta Scientiarum: Biological Sciences, 2011
Micona sellowiana in different types of vegetation (Grassland, Montane Atlantic forest, Upper Montane Atlantic forest and Araucaria Pine forest). Although such variability could be due to phenotypic plasticity, an alternative explanation for this ...

Adaptive Introgression: An Untapped Evolutionary Mechanism for Crop Adaptation

Frontiers in Plant Science, 2019
Global environmental changes strongly impact wild and domesticated species biology and their associated ecosystem services. For crops, global warming has led to significant changes in terms of phenology and/or yield.

Dispersal and gene flow in free-living marine nematodes [PDF]

, 2013
Dispersal and gene flow determine connectivity among populations, and can be studied through population genetics and phylogeography. We here review the results of such a framework for free-living marine nematodes.

Inferring gene regulation dynamics from static snapshots of gene expression variability [PDF]

, 2021
Inferring functional relationships within complex networks from static snapshots of a subset of variables is a ubiquitous problem in science. For example, a key challenge of systems biology is to translate cellular heterogeneity data obtained from single-cell sequencing or flow-cytometry experiments into regulatory dynamics.
