Journal ArticleDOI
Revisiting the taxonomy of the Rattini tribe: a phylogeny-based delimitation of species boundaries
Marie Pagès,Yannick Chaval,Vincent Herbreteau,Surachit Waengsothorn,Jean-François Cosson,Jean-Pierre Hugot,Serge Morand,Johan Michaux,Johan Michaux +8 more
TL;DR: This study explores and highlights the limits of the current taxonomy of the Rattini tribe, one of the most difficult groups of mammals, and lays the foundations to better investigate rodent-born diseases in South East Asia.
Journal ArticleDOI
Epidemiology of Leptospira Transmitted by Rodents in Southeast Asia
Jean-François Cosson,Mathieu Picardeau,Mathilde Mielcarek,Caroline Tatard,Yannick Chaval,Yupin Suputtamongkol,Philippe Buchy,Sathaporn Jittapalapong,Vincent Herbreteau,Serge Morand +9 more
TL;DR: Strain typing confirmed rodents as reservoirs for human leptospirosis, and differences in habitat requirements for L. interrogans and L. borgpetersenii supported differential transmission modes.
Journal ArticleDOI
Migration and recovery of the genetic diversity during the increasing density phase in cyclic vole populations.
TL;DR: It is provided that in cyclic populations of the fossorial water voles, the relative influence of drift operating during low density populations and migration occurring principally while population size increases interacts closely to maintain high genetic diversity.

Protocols for field and laboratory rodent studies
Vincent Herbreteau,Sathaporn Jittapalapong,Worawut Rerkamnuaychoke,Yannick Chaval,Jean-François Cosson,Serge Morand +5 more
TL;DR: Protocols for field and laboratory rodent studies present the best practices for the studies of rodents and rodent-borne pathogens and parasites from the field to the laboratory.
Journal ArticleDOI
Stress and demographic decline: a potential effect mediated by impairment of reproduction and immune function in cyclic vole populations.
Nathalie Charbonnel,Yannick Chaval,Karine Berthier,Julie Deter,Serge Morand,Rupert Palme,Jean-François Cosson +6 more
TL;DR: A significant negative correlation was observed between concentrations of FCMs and both immunocompetence and body condition during population decline, which might reflect an impairment of the female reproductive capability in high densities and accelerated senescence affecting immune function during decline, both arising from chronic stress.
