Inondation et horloge biologique / Séminaire international : gestion intégrée des ressources naturelles en zones inondab...
In Madagascar the rodent problem is linked to one species, the black rat (#Rattus rattus$). This chapter will describe its population dynamics in agro-ecosystems and its impact in agricultural crops, in stored grain, on human health and on the endemic rodent community. The black rat has spread absolutely everywhere : from sea level to more than 2,0...
A better understanding of rodent population dynamics and strategies for surviving in various habitats can be gained from combined studies of genetics, ecology, ecophysiology and chronobiology. Each of these disciplines can contribute complementary information to improve rodent pest management (RPM). Field studies of the ecophysiology of several spe...
Les pratiques agricoles d'accroissement des surfaces cultivées et d'intensification ont entraîné de profondes transformations des écosystèmes (rapide recul de la forêt, évolution du faciès de l'entomofaune, phénomènes de résistance aux insecticides...) ainsi que des systèmes de production (forte utilisation d'intrants, relation de dépendance vis à ...
