Phylogeography of the crown-of-thorns starfish in the Indian Ocean [PDF]

, 2012
Background: Understanding the limits and population dynamics of closely related sibling species in the marine realm is particularly relevant in organisms that require management.

Patterns of gene flow define species of thermophilic Archaea.

PLoS Biology, 2012
Despite a growing appreciation of their vast diversity in nature, mechanisms of speciation are poorly understood in Bacteria and Archaea. Here we use high-throughput genome sequencing to identify ongoing speciation in the thermoacidophilic Archaeon ...

Speciation over the edge: gene flow among non-human primate species across a formidable biogeographic barrier [PDF]

Royal Society Open Science, 2017
Many genera of terrestrial vertebrates diversified exclusively on one or the other side of Wallace’s Line, which lies between Borneo and Sulawesi islands in Southeast Asia, and demarcates one of the sharpest biogeographic transition zones in the world ...

Speciation with gene flow could be common [PDF]

Molecular Ecology, 2008
AbstractThe likelihood of speciation in the face of homogenizing gene flow (i.e. without complete geographical isolation) is one of the most debated topics in evolutionary biology. Demonstrating this phenonemon is hampered by the difficulty of isolating the effects of time since population divergence vs.

Fuzzy species limits in Mediterranean gorgonians (Cnidaria, Octocorallia): inferences on speciation processes [PDF]

, 2017
The study of the interplay between speciation and hybridization is of primary importance in evolutionary biology. Octocorals are ecologically important species whose shallow phylogenetic relationships often remain to be studied. In the Mediterranean Sea,

Extensive gene flow in secondary sympatry after allopatric speciation

National Science Review, 2022
Abstract In the conventional view, species are separate gene pools delineated by reproductive isolation (RI). In an alternative view, species may also be delineated by a small set of ‘speciation genes’ without full RI, a view that has gained broad acceptance.

Selection and environmental adaptation along a path to speciation in the Tibetan frog Nanorana parkeri. [PDF]

, 2018
Tibetan frogs, Nanorana parkeri, are differentiated genetically but not morphologically along geographical and elevational gradients in a challenging environment, presenting a unique opportunity to investigate processes leading to speciation. Analyses of

Genetic, phenotypic and ecological differentiation suggests incipient speciation in two Charadrius plovers along the Chinese coast

BMC Evolutionary Biology, 2019
Background Speciation with gene flow is an alternative to the nascence of new taxa in strict allopatric separation. Indeed, many taxa have parapatric distributions at present. It is often unclear if these are secondary contacts, e.g.

The uplift of the Hengduan Mountains contributed to the speciation of three Rhododendron species

Global Ecology and Conservation, 2022
Plant speciation in mountain systems is crucial for shaping plant biodiversity, particularly for those endemic species with small populations. The mountain-geobiodiversity hypothesis (MGH) is among the possible mechanisms underlying mountain biodiversity.
