The origin of Rattus Rattus on the Iles Eparses, Western Indian Ocean
Journal of Biogeography, 2011Co-Authors: James C Russell, Dianne M. Gleeson, Matthieu Le CorreAbstract:Tollenaere et al. (Journal of Biogeography, 2010, 37, 398–410) present a phylogeographic analysis of Rattus Rattus for the Western Indian Ocean, with particular emphasis on Madagascar, but do not include samples from three island groups centrally located in the Mozambique Channel. Haplotypes from these islands provide additional information on the colonization pathways of R. Rattus in the Western Indian Ocean region. For each of the three Iles Eparses groups in the Mozambique Channel, we test the competing hypotheses that colonization by R. Rattus was most likely: (1) from the Arabian Peninsula, (2) from East Africa, (3) from Madagascar, or (4) from independent shipping. These results are combined with historical observations of the presence of R. Rattus on these islands to give stronger inference on the colonization pathways. Additionally, more accurate colonization dates provide guidance for contemporary conservation management.

Reconstruction of the colonization of southern Madagascar by introduced Rattus Rattus
Journal of Biogeography, 2005Co-Authors: Melanie Hingston, Steven M. Goodman, Jörg U. Ganzhorn, Simone SommerAbstract:Aim Description of the genetic differentiation of Rattus Rattus populations in southern Madagascar. Reconstruction of the colonization pattern of R. Rattus in southern Madagascar and of the origin of introduced R. Rattus. Location Southern Madagascar. Methods We analysed the variation in the non-coding hypervariable region 1 (HVR I) of the mitochondrial control region in 93 individuals from six different sampling sites. The origin of the introduced individuals was examined by comparing Malagasy R. Rattus sequences to data available from outside Madagascar. Results Thirteen distinct mtDNA control region haplotypes (H1–H13) were distinguished. Only 11 sites (2.6%) were variable within a 419-bp sequence. Three haplotypes were shared between the sampling areas, though only one haplotype was ubiquitous accounting for 63.4% of all individuals. Population genetic differences (ΦST) between sampling sites ranged from 0.13 to 0.31. amova results showed that the majority of variation (86.1%) was assigned to diversity within populations. Except for two R. Rattus sequences from India, all other outgroup samples (New York, Great Britain, France and French Polynesia) belonged to an identical haplotype. Main conclusions The spatial distribution and frequency of haplotypes and associated phylogenetic analysis provisionally suggest the Tolagnaro harbour as the place of the founder population from which R. Rattus spread into southern Madagascar. Given currently available samples, these populations are most closely related to rats from the Indian subcontinent. Corroboration of each of these hypotheses will require additional geographical sampling, particularly from northern Madagascar and Africa.

Isolation and characterization of microsatellites in Rattus Rattus.
Molecular Ecology Resources, 2008Co-Authors: Anne Loiseau, Soanandrasana Rahelinirina, Lila Rahalison, Ann Konecny, Jean-marc Duplantier, Carine BrouatAbstract:: We isolated and characterized 10 microsatellite loci in the black rat Rattus Rattus (Muridae, Rodentia), a widespread invasive species largely known to cause serious problems in agriculture and human health. Polymorphism was studied in two populations, one from Madagascar and one from Senegal. It ranged from three to 12 alleles in Madagascar, and from two to five alleles in Senegal. Together with the loci previously adapted from Rattus norvegicus, this set of markers should allow the conduct of thorough studies on the genetic structure of natural populations of R. Rattus.
