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

open access: yes, 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

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

open access: yesEvolutionary 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 ...

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

open access: yesEvolutionary 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.

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

open access: yesActa 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

open access: yesFrontiers 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.

Species Delimitation with Gene Flow [PDF]

open access: yesSystematic Biology, 2016
Species are commonly thought to be evolutionarily independent in a way that populations within a species are not. In recent years, studies that seek to identify evolutionarily independent lineages (i.e., to delimit species) using genetic data have typically adopted multispecies coalescent approaches that assume that evolutionary independence is formed ...

Microsatellite-Based Genetic Structure and Diversity of Local Arabian Sheep Breeds

open access: yesFrontiers in Genetics, 2018
The genetic diversity of the sheep breeds in the Arab countries might be considered to be a mirror of the ecology of the region. In this study, the genetic structure and diversity of sheep breeds from Saudi Arabia (Harri, Najdi, Naemi, Arb, and Rufidi ...

Genetic diversity, population structure, and relationships among wild and domesticated almond (Prunus spp.) germplasms revealed by ISSR markers

open access: yesAdvances in Horticultural Science, 2020
The use of diverse almond genetic resources to expand the genetic bases of commercial cultivars is important for almond breeders. Iran is within the center of origin for almond and enjoys a huge diversity of wild species and local cultivars of this ...
