Larger species have lower beta diversity and are replaced less frequently across landscapes and as a result tend to occupy more of their range ( see Occupancy-abundance relationship relationships ) ( Brown and Maurer, 1989; Brown and Nicoletto, 1991 ).
12.
The group has repeatedly been proposed as biological indicators of ecological conditions or biological diversity within neotropical forests, but individual sites harbor between 10 and 50 species, for the most part, and beta diversity is often great, even over relatively short distances.
