Abstract
Summary: Elephants were observed for two dry seasons and the intervening wet season in Ruaha National Park, Tanzania. The behaviour of cows was influenced to a greater extent by weather than was the behaviour of bulls. Variations in bulls' ranging behaviour could be explained by the proportion of the bull population that was sexually active at any particular time of year.In the mid dry season, when there was very little food available, bulls moved short distances each day, while cows travelled long distances in search of food for themselves and their dependent offspring. Later in the dry season the benefits of long day ranges were outweighed by increasing juvenile mortality.Résumé: Des éléphants ont été observés durant deux saisons sèches et la saison des pluies intermédiaire, au Ruaha N.P. en Tanzanie. Le comportement des femelles est plus influencé par le temps que celui des mâles. Les variations dans le comportement des mâles pourraient être expliquées par la proportion de la population des mâles sexuellement active à chaque moment précis de l'année.Au milieu de la saison sèche, quand il y a peu de nourriture disponible, les mâles parcourent de courtes distances chaque jour alors que les femelles couvrent de longs trajets à la recherche de nourriture pour elles‐mêmes et leur progéniture. Plus tard dans la saison sèche, les bénéfices de longs déplacements sont contrebalancés par l'augmentation de la mortalité juvénile.This publication has 11 references indexed in Scilit:
