Abstract

Summary Rodent populations in cultivated and fallow fields in Tanzania were sampled by trapping. Mastomys natalensis (Smith) was by far the most abundant rodent in these habitats (62% or more of samples). Estimates of densities of this rodent were obtained by removal trapping at scattered localities in Tanzania (range 23–236 ha‐1) and from a catch‐mark‐release (CMR) study through a seasonal cycle (range 40–384 ha‐1). Home ranges were analysed using CMR data. Seasonal variation in home‐range size was not found, but reproductive males “had larger ranges than females and subadults. Résumé On a prélevé au moyen de piéges des échantillons des populations de rongeurs dans des champs cultivés et dans d'autres en jachère. Mastomys natalensis (Smith) était de loin le rongeur le plus abondant dans ces habitats (62% ou plus des échantillons). On a obtenu des estimations de la densité de ce rongeur au moyen de pièges dispersés dans différentes localités en Tanzanie, les animaux n'étant pas relâches (distribution 23–236/ha), et par une étude de capture‐marquage‐recapture (CMR) pendant un cycle saisonnier (distribution 40–384/ha). On a analysé les espaces vitaux en se servant des données de CMR. On n'a pas trouvé de variation saisonnière de la taille de l'espace vital mais les mâles reproducteurs ont des territoires plus vastes que les femelles et les subadultes.
