Understanding how forest cover is related to patch attributes such as size, shape, and isolation, and how
this influences the occurrence of a species in fragmented landscapes is an important question in landscape
ecology and conservation biology. To study the effects of fragmentation on patch occupancy by the
critically endangered Mexican mantled howler monkey (Alouatta palliata mexicana) in the Los Tuxtlas
region of Mexico, we selected three landscapes of ca. 5,000 ha, which differed in their remaining forest
cover (24, 11, and 4%). For each landscape, we related patch occupancy to forest cover, patch size and
shape, and four isolation parameters. Landscape attributes varied according to forest cover, and the
percentage of occupation was greater in landscapes with more forest cover. The attributes affecting the
