“…Os resultados, que incluem dados moleculares, morfológicos e cariotípicos, indicam que grande parte das atuais espécies reconhecidas se trata de um complexo de espécies. Dessa forma, o conceito e a distribuição de todas as espécie do gênero devem ser revistas de acordo com este e outros trabalhos, tais como Gomes-Júnior et al (2016); Pardiñas et al (2016); e Rocha et al (2018).…”

Oecomys franscicorum ocorre na Argentina e Brasil, onde foi registrada no Pantanal dos estados do Mato Grosso e Mato Grosso do Sul. Está presente em apenas duas Unidades de Conservação e, aparentemente, associada a ambientes florestais. Apesar da expansão das atividades agropecuárias e dos intensos incêndios na região, não há indícios de que o impacto dessas ameaças coloque sua população em risco de extinção em curto prazo. Portanto, Oecomys franciscorum foi categorizada como Menos Preocupante (LC).

“…The introduction of genetic methods and the subsequent emergence of the genetic species concept has led to a sharp increase in the number of studies that have utilised data from molecular genetic analysis for species delimitation. Cryptic species are now common in mammals in general, and particularly in the Cricetidae family (Pauperio et al 2012;Bulatova et al 2013;Rivera et al 2018;Rocha et al 2018;Bezerra et al 2020).…”

Signatures of genetic isolation of the three lineages of the narrow-headed vole Lasiopodomys gregalis (Cricetidae, Rodentia) in a mosaic steppe landscape of South Siberia

et al. 2021

Geographic isolation is among the most important factors initiating speciation in mammals. The narrow-headed vole Lasiopodomys gregalis is a widely distributed species in steppe habitats of South Siberia that are highly fragmented by mountain ranges. There are three major mostly allopatric mitochondrial lineages of L. gregalis described throughout the distribution range that most plausibly split in the Middle Pleistocene. This study applies the analysis of five microsatellite loci and species distribution modelling to understand the patterns of isolation and migration between L. gregalis populations in South Siberia and in particular in Tuva basin where all three lineages occur simultaneously. Microsatellite analysis supported the population differentiation revealed previously, with three clusters corresponding to mitochondrial lineages and indicated that gene flow between them is strongly limited. There were only traces of hybridisation in the population near the contact zone of lineages B and C. SDM analysis predicted only a small number of potential contact zones between L. gregalis lineages and barriers corresponding to landscape heterogeneity. We presume that the forested mountain ranges act as the main insurmountable barriers to gene flow between major genetic lineages of L. gregalis.
