主 题:Madagascar Rattus rattus reproductive ecology rodent control
摘 要:The black rat(Rattus rattus)poses a severe threat to food security and public health in Madagascar,where it is a major cause of pre-and post-harvest crop losses and an important reservoir for many zoonotic diseases,including ***,ecologically based rodent management(EBRM)strategies have been developed using ecologi-cal information to inform decisions on where and when to target *** could deliver improved health and well-being outcomes in Madagascar if adapted to the local ecological *** data collected from removal studies,we explored spatio-temporal patterns in the breeding activity of the black rat(***)in domestic and agricultural habitats across Madagascar and investigated to what extent these trends are influenced by rainfall and rat *** identified clear spatio-temporal variation in the seasonality of *** *** was highly seasonal both inside and outside of houses,but seasonal trends varied between these two ***-sonal trends were explained,in part,by variation in rainfall;however,the effect of rainfall on reproductive rates did itself vary by season and habitat type.A decline in breeding intensity with increasing rat density was recorded outside of *** has important implications for control,as populations may compensate for removal through increased *** recommend that sustained control initiated before the main breeding season,combined with improved hygiene and adequate rodent-proofing in homes and grain stores,could curtail population growth and reduce pre-and post-harvest losses provided that these measures overcome the compensatory response of rodent populations.
