Résumé |
The lemurs of Madagascar are known for their extraordinary species diversity. Often several species and congeneric species (genera Microcebus, Cheirogaleus, Hapalemur, Eulemur) occur sympatrically in the same habitat.I found significant interspecific differences in the choice of sleeping sites: smaller lemurs chose smaller trees and used more sleeping sites than larger lemurs. Species differed also significantly in the vertical dimension of forest utilisation. I found Cheirogaleus major using the upper part of thetrees. C. medius used the middle parts and Microcebus murinus used the understorey during their nocturnal activity. In conclusion, the three species differed mainly in their vertical habitat utilisation and showed a vertical stratification. |
