| Summary: | Black rats are major invasive vertebrate pests with severe ecological, economic and health impacts. Remarkably, their evolutionary history has received little attention, and there is no firm agreement on how many species should be recognized within the black rat complex. This species complex is native to India and Southeast Asia. According to current taxonomic classification, there are three taxa living in sympatry in several parts of Thailand, Cambodia and Lao People's Democratic Republic, where this study was conducted: two accepted species (Rattus tanezumi, Rattus sakeratensis) and an additional mitochondrial lineage of unclear taxonomic status referred to here as ‘Rattus R3’. We used extensive sampling, morphological data and diverse genetic markers differing in rates of evolution and parental inheritance (two mitochondrial DNA genes, one nuclear gene and eight microsatellite loci) to assess the reproductive isolation of these three taxa. Two close Asian relatives, Rattus argentiventer and Rattus ... : IRBP-Pages-2012Fasta alignment of IRBP sequences used in Pages et al., 2012Mito-Pages-2012Fasta alignment of mitochondrial data used in Pages et al., 2012Microsat-Pages-2012Microsatellite data used in Pages et al., 2012Morphological dataWe assessed the morphological differences between 328 adult specimens from the R3 and R. tanezumi mt lineages. Five linear measurements were considered: head + body length, tail length, hind-foot length, ear length and head length. All measurements were made with a ruler (precision 1 mm), with the exception of head length, which was measured with a caliper (precision 0.1 mm). Specimens were sexed and classified as adults on the basis of both complete development of the mandibular row of teeth and sexual maturity (full development of seminal vesicles and vulva opening, for males (M) and females (F), respectively)Morphological-Data.xls ... |
