Seed Dispersers

Primates are primary seed dispersers for many tropical tree species. Different species of primates vary considerably in ranging and feeding behaviour, seed processing, and in seed defecation patterns. Here we compare the role of two arboreal primate species, howlers (Alouatta palliata), and white-faced monkeys (Cebus capucinus) as seed dispersers in a tropical dry forest in Costa Rica. We found that Cebus produce smaller defecations, spend shorter times feeding per tree, have longer seed dispersal distances, and produce a more scattered pattern of seed deposition in the forest than Alouatta. In addition, Cebus moved more frequently between trees, and consumed fruits of more species than Alouatta. We examined the consequences of the contrasting defecation patterns produced by Cebus and Alouatta on the early seed fate of Acacia collinsii. We found that quantity, but not the identity (Cebus vs. Alouatta) of faecal material affected post-dispersal activity. Seeds in scattered faeces, sufficiently apart from each other (the common defecation pattern of white-faced monkeys), had higher short-term survival than seeds in clumped patterns of faeces (the pattern associated with Alouatta).

Stable Oxygen

Stable oxygen isotopes are increasingly used in ecological research. Here, I present oxygen isotope (δ 18 O) values for bone carbonate and collagen from howler monkeys ( Alouatta palliata ), spider monkeys ( Ateles geoffroyi ) and capuchins ( Cebus capucinus ) from three localities in Costa Rica. There are apparent differences in δ 18 O carbonate and δ 18 O collagen among species. Monkeys from moist forest have significantly lower isotope values than those from drier localities. Because patterns are similar for both substrates, discrimination (Δ) between δ 18 O carbonate and δ 18 O collagen is relatively consistent among species and localities (17.6 ± 0.9‰). Although this value is larger than that previously obtained for laboratory rats, consistency among species and localities suggests it can be used to compare δ 18 O carbonate and δ 18 O collagen for monkeys, and potentially other medium-bodied mammals. Establishing discrimination for oxygen between these substrates for wild monkeys provides a foundation for future environmental and ecological research on modern and ancient organisms.

AbstractTwo genera of nonhuman primates that include howler monkeys (Alouatta palliata and Alouatta pigra) and spider monkeys (Ateles geoffroyi) currently are located throughout the Maya region. It has been suggested that the Classic Maya associated these monkeys, especially howler monkeys, with the arts. This view is exemplified in the Popol Vuh and in depictions of monkey-man scribes on Late Classic (c. a.d. 550–900) ceramics. This paper provides evidence that a third genus, the capuchin monkey (Cebus capucinus), is also located in the southern Maya region and may have extended as far north as Belize within the last century. Supporting data are drawn from historic accounts, artifact and faunal analysis, and linguistic data. It is also proposed, based on an interspecific comparison of morphological and behavioral characteristics, that capuchin monkeys rather than howler monkeys are the animals represented in depictions of monkey scribes.
