Sympatric speciation: when is it possible in bacteria? [PDF]
PLoS ONE, 2013 According to theory, sympatric speciation in sexual eukaryotes is favored when relatively few loci in the genome are sufficient for reproductive isolation and adaptation to different niches. Here we show a similar result for clonally reproducing bacteria,

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

Searching for Sympatric Speciation in the Genomic Era [PDF]
BioEssays, 2019 Sympatric speciation illustrates how natural and sexual selection may create new species in isolation without geographic barriers. However, recent genomic reanalyses of classic examples of sympatric speciation reveal complex histories of secondary gene flow from outgroups into the radiation.

Host diet shapes functionally differentiated gut microbiomes in sympatric speciation of blind mole rats in Upper Galilee, Israel [PDF]
Frontiers in Microbiology, 2022 The gut microbiome is important for host nutrient metabolism and ecological adaptation. However, how the gut microbiome is affected by host phylogeny, ecology and diet during sympatric speciation remain unclear.

Incipient sympatric speciation in wild barley caused by geological-edaphic divergence [PDF]
Life Science Alliance, 2020 Sympatric speciation is still contentious but here based on genome-wide analysis; we show incipient sympatric speciation of an emerging new wild barley species from Hordeum spontaneum , the progenitor of all cultivated barleys at “Evolution Plateau” (EP),

Ecological disruptive selection acting on quantitative loci can drive sympatric speciation [PDF]
npj Systems Biology and ApplicationsThe process of speciation generates biodiversity. According to the null model of speciation, barriers between populations arise in allopatry, where, prior to biology, geography imposes barriers to gene flow.

The emergence of ecotypes in a parasitoid wasp: a case of incipient sympatric speciation in Hymenoptera? [PDF]
BMC Ecology and Evolution, 2021 Background To understand which reproductive barriers initiate speciation is a major question in evolutionary research. Despite their high species numbers and specific biology, there are only few studies on speciation in Hymenoptera.

Secondary sympatry caused by range expansion informs on the dynamics of microendemism in a biodiversity hotspot. [PDF]
PLoS ONE, 2012 Islands are bounded areas where high endemism is explained either by allopatric speciation through the fragmentation of the limited amount of space available, or by sympatric speciation and accumulation of daughter species.
