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.

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.

Simulated ecology-driven sympatric speciation [PDF]
Physical Review E, 2001 We introduce a multi-locus genetically acquired phenotype, submitted to mutations and with selective value, in an age-structured model for biological aging.

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),

Journal of Threatened Taxa, 2010 The prevailing notion is that allopatry is the main driver of divergence between populations, leading to speciation. But a number of recent studies show that speciation occurs in sympatry too, that sympatric speciation is quite common, perhaps more ...

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.

Sympatric speciation in structureless environments. [PDF]
BMC Evol Biol, 2016 Darwin and the architects of the Modern Synthesis found sympatric speciation difficult to explain and suggested it is unlikely to occur. Increasingly, evidence over the past few decades suggest that sympatric speciation can occur under ecological conditions that require at most intraspecific competition for a structured resource.

Sympatric speciation in killer whales? [PDF]
Heredity (Edinb), 2015 Sympatric speciation was long assumed to be a rare, if not impossible, phenomenon. Although theoreticians have identified the conditions and evolutionary processes under which sympatric speciation may be possible, empirical support of divergence that initiated and proceeded in sympatry has been limited to studies of monophyletic, geographically ...

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,
