Methods of estimating ungulate populations in tropical forests

摘要: Summary Pellet group counts, drive counts and track were used to estimate population abundances of one small four large species duiker (Cephalophus sp.) in a moist evergreen forest northeastern Zaire. Procedures develop estimates based on line transect pellet groups are described. The Fourier Series estimator proved be useful for estimating densities groups. Comparisons made between abundance heavily lightly hunted areas, species. three census methods consistent showing no significant difference animal the populations or smaller relative larger All showed potential as indices assessing trends rare elusive environments. Drive may also densities.
