Evolution of blind beetles in isolated aquifers: a test of alternative modes of speciation.
PLoS ONE, 2012 Evidence is growing that not only allopatric but also sympatric speciation can be important in the evolution of species. Sympatric speciation has most convincingly been demonstrated in laboratory experiments with bacteria, but field-based evidence is ...

BMC Evolutionary Biology, 2010 Background Teleost fishes of the Coregonidae are good model systems for studying postglacial evolution, adaptive radiation and ecological speciation. Of particular interest is whether the repeated occurrence of sympatric species pairs results from in ...

Description of six new species of the subgenus Panophrys within the genus Megophrys (Anura, Megophryidae) from southeastern China based on molecular and morphological data [PDF]
ZooKeys, 2019 The diversity of the subgenus Panophrys within the genus Megophrys has been revealed to be extremely underestimated from southeastern China. Herpetological surveys coupled with extensive sampling in a longitudinal mountain belt located in southeastern ...

Crater lake cichlids individually specialize along the benthic-limnetic axis [PDF]
, 2014 A common pattern of adaptive diversification in freshwater fishes is the repeated evolution of elongated open water (limnetic) species and high-bodied shore (benthic) species from generalist ancestors.

Genetic differentiation in Scottish populations of the pine beauty moth Panolis flammea (Lepidoptera: Noctuidae) [PDF]
, 2005 Pine beauty moth, Panolis flammea (Denis & Schiffermüller), is a recent but persistent pest of lodgepole pine plantations in Scotland, but exists naturally at low levels within remnants and plantations of Scots pine.

Divergent functional traits in three sympatric Arctic charr Salvelinus alpinus morphs are not coupled with the age of the lineage divergence [PDF]
, 2016 Three genetically discrete morphs of Arctic charr in Loch Rannoch, Scotland originated from a recent divergence within the lake (in situ) (piscivore and benthivore morphs) and from secondary contact of two older lineages (ex situ; a planktivore–piscivore/

Widespread genomic divergence during sympatric speciation [PDF]
Proceedings of the National Academy of Sciences, 2010 Speciation with gene flow is expected to generate a heterogeneous pattern of genomic differentiation. The few genes under or physically linked to loci experiencing strong disruptive selection can diverge, whereas gene flow will homogenize the remainder of the genome, resulting in isolated “genomic islands of speciation.” We conducted an ...

Characterisation of species and diversity of Anopheles gambiae Keele Colony [PDF]
, 2016 Anopheles gambiae sensu stricto was recently reclassified as two species, An. coluzzii and An. gambiae s.s., in wild-caught mosquitoes, on the basis of the molecular form, denoted M or S, of a marker on the X chromosome. The An.

Multiple phase transitions in an agent-based evolutionary model with neutral fitness [PDF]
, 2017 Null models are crucial for understanding evolutionary processes such as speciation and adaptive radiation. We analyse an agent-based null model, considering a case without selection—neutral evolution—in which organisms are defined only by phenotype ...

BMC Evolutionary Biology, 2007 Background Speciation often occurs in complex or uncertain temporal and spatial contexts. Processes such as reinforcement, allopatric divergence, and assortative mating can proceed at different rates and with different strengths as populations diverge ...
