The roles of density-dependent and density-independent factors in the dynamics of tropical large herbivore populations are poorly understood. Understanding these dynamics is particularly important if the herbivore is prey for an apex predator of conservation concern because a decline in the prey could cause the predator to decline. We tested hypotheses about the roles of density-dependent and density-independent factors in the dynamics of 2 tropical ungulates, Rusa deer (Rusa timorensis) and wild pigs (Sus scrofa), in Komodo National Park, eastern Indonesia. We counted the dung of Rusa deer and wild pigs (a validated index of abundance for these 2 species) along permanently marked transects ..View full abstract
We thank the Komodo National Park rangers and technical staff for assisting with fieldwork. A collaborative program between the Komodo Survival Program and the Indonesian Department of Forest Protection and Nature Conservation (PHKA) was established to conduct the research. The American Zoo and Aquarium Association, the Taronga Conservation Society, the Ocean Park Conservation Foundation (OPCF) Hong Kong, and the Mohamed Bin Zayed Species Conservation Fund provided financial support to the Komodo Survival Program. We thank K. Monteith and 3 anonymous reviewers for their constructive comments on the draft manuscript, and J. Birtles (Organic Editing) for editorial services.
