Exploitation of Mabea fistulifera nectar by marmosets (Callitrix flaviceps) and muriquis (Brachyteles
arachnoides) in south-east Brazil.
Senna multijuga is also recognized as an important species for ecological interactions, for instance, it is a notable host for cicadas, and therefore, armadillos commonly make holes in the base of its trunk looking for the nymphs (Carvalho 2004); its leaves, flowers and fruits are sources of food for the spider-monkey (Brachyteles
arachnoids, Mendonca-Filho 1996) and its seeds are often damaged before dispersal by Bruchidae beetles (Sari & Ribeiro-Costa 2005, Sari et al.
In one study, a researcher found that lianas constituted 27% of the diet for the brown howling monkey (Aouatta guariba) and 33% of the diet for the Southern muriqui (Brachyteles
arachnoides) (Martins, 2009).
Behavioral and endocrine characteristics of the reproductive cycle in wild muriqui monkeys, Brachyteles
Of great interest are the primate species of the forest, including the several species of lion tamarin (Leontopithecus sp.), muriqui (Brachyteles
arachnoids), and howler monkeys (Alouatta palliata), many of which are critically endangered (Downie 2001).
Among these are the muriquis (the two species in the genus Brachyteles
), which are the New World's largest monkeys, and the diminutive lion tamarins (the four Leontopithecus species).
