Fruit characters as a basis of fruit choice and seed dispersal in a tropical forest vertebrate community
The analyses of dispersal syndromes show that fruit species partitioning occurs more between mammal taxa than between mammals and birds, and suggest how fruit characters could have evolved under consumer pressure as a result of consumer roles as dispersers or seed predators. Expand
Phylogeography of the introduced species Rattus rattus in the western Indian Ocean, with special emphasis on the colonization history of Madagascar
Phylogeographic patterns supported the hypothesis of human-mediated colonization of R. rattus from source populations in either the native area (India) or anciently colonized regions (the Arabian Peninsula) to islands of the western Indian Ocean. Expand
Phylogeography of the Guinea multimammate mouse (Mastomys erythroleucus): a case study for Sahelian species in West Africa
Aim To investigate the phylogeographical structure of the Guinea multimammate mouse, Mastomys erythroleucus (Temminck, 1853), a widespread murid rodent in sub-Saharan (Sahel and Sudan) savannas, forExpand
Autosome and Sex Chromosome Diversity Among the African Pygmy Mice, Subgenus Nannomys (Murinae; Mus)
The C-banding analyses performed showed that among the species carrying X-autosome translocations, one followed the expected pattern, while the other did not, and functional isolation of the sex and autosome compartments must involve other repetitive sequences or genomic traits that require further molecular characterization.

Reproductive biology and postnatal development in sloths, Bradypus and Choloepus: review with original data from the field (French Guiana) and from captivity
Field data collected in French Guiana over a period of 16 months in the framework of an animal rescue carried out during the filling of a hydroelectric dam, and captive data obtained from breeding records from different zoos are presented to determine the most likely values for different reproductive parameters in sloths.

From the recent lessons of the Malagasy foci towards a global understanding of the factors involved in plague reemergence.
From the analysis of well-documented human plague cases in Madagascar, the causes of re-emergence that can be generalized to most world foci are underline, and can help define environments at risk where the threat of new emergence lurks. Expand
Understanding the Persistence of Plague Foci in Madagascar
Rattus rattus, the main host of Y. pestis in Madagascar, is found to exhibit high resistance to plague in endemic areas, opposing the concept of high mortality rates among rats exposed to the infection. Expand
First Isolation and Direct Evidence for the Existence of Large Small-Mammal Reservoirs of Leptospira sp. in Madagascar
This first isolation of pathogenic Leptospira strains in this country may significantly improve the detection of specific antibodies in human cases and suggest a high level of environmental contamination, consistent with probable transmission of the infection to humans. Expand
A mitochondrial phylogeographic scenario for the most widespread African rodent, Mastomys natalensis
A scenario is proposed where climate-driven processes may have played a primary role in the differentiation among phylogroups and six well-supported phylog groups, differentiated during the Pleistocene were evidenced. Expand
