Fig 2.
Individual-based rarefaction curves of the number of plant species used as food sources by brown howler monkeys in six study sites in the State of Rio Grande do Sul, Brazil.
Curves for the small fragments (A) and the large fragments (B) are shown. Dashed lines indicate 95% confidence intervals.
Table 1.
Percentage of total feeding records and importance value index (in parentheses) for the top food species in the diet of brown howlers in each study fragment.
Growth form (GF) also shown.
Table 2.
Percentage of total feeding records on the alien tree species (N = 9) exploited by brown howler monkeys in small fragments.
Fig 3.
Intermonth diet similarity between study groups inhabiting small and large fragments.
The line within a box represents the median of the Morisita-Horn index, the box represents the 25% and 75% interquartiles (IQR), and the whiskers represent the IQR multiplied by 1.5. Dots represent the actual data points for each group. Different letters indicate significant differences (P<0.05).
Fig 4.
Percentage of feeding records devoted to each plant item in the diet of brown howler monkeys in large and small Atlantic forest fragments.
Different letters above bars indicate significant differences (P<0.05).
Fig 5.
Percentage of feeding records devoted to each growth form in the diet of brown howler monkeys in large and small Atlantic forest fragments.
Different letters above bars indicate significant differences (P<0.05).

Linear regressions between the availability (independent variable) and the consumption (dependent variable) of seasonal plant items of the top food species by the brown howler monkey study groups.
