Rodents of the Afar Triangle (Ethiopia): geographical isolation causes high level of endemismArid regionDNA barcodingGerbilsPhylogeographySomali-Masai savannaThe Afar Triangle in easternmost Africa is one of biogeographically important regions, whose recent biota is virtually unknown. Here we evaluated ...
Species-level divergences for some of the genera in the SEAMA have been estimated, with divergence estimates ranging from relatively recently (e.g., Plio-Peistocene) to fairly ancient (e.g., Mid-Miocene), TableSI2. As of yet, no common patterns have emerged, in part due to information o...
The application of phylogenetic inference methods, to data for a set of independent genes sampled randomly throughout the genome, often results in substant... M Chen,LS Kubatko - 《Theoretical Population Biology》 被引量: 330发表: 2009年 Detecting isolation by distance using phylogenies of genes....
The isolation of habitats may also promote this mechanism52,53. Methods Taxon sampling and statistical analysis. Sixty-one microscope slide-mounted specimens of Ch. sti- pae stipae were examined (three slide-mounted specimens of Ch. tshernavini Mordv. were also examined as an out group) ...
The geographic isolation and evolutionary history of Antarctica produced a unique habitat supporting endemicity of microbes (Fernandez et al., 2011). However, there is need to be careful as global microbial data still have to be unveiled and available gene databank is incomplete. For example ...
A total of 138 individuals from 16 populations were collected, largely covering the natural distribution ofR. kwangtungense. The genetic diversity within theR. kwangtungensepopulations was extremely low (HO= 0.048 ± 0.019;HE= 0.033 ± 0.011). Mantel tests revealed isolation-by-distance...
Although that may be the case, since the three species seem to have relatively stabilised population sizes after 2010 this could suggest progressive resource partitioning with a level of ecological isolation following the initial dominance interactions. Since the westward expansion of the ranges of the...
Unsurprisingly, the more precise positioning refers to individuals coming from Ogliastra (east Sardinia), since this area is characterized both by high altitude, high endogamy and relative cultural isolation, whereas populations from the western shores are considered to be more admixed. We found a ...
The Mantel test for isolation by distance revealed a positive, but non-significant, correlation between population genetic differentiation (F ST ) based on the microsatellite data and geographical distance (R 2 = 0.44; P = 0.09; Figure 4). Table 2 Pairwise genetic differentiation ( F...
