“…This preference has been reported for other Mexican southeastern populations of Ateles (Martínez and GalindoLeal, 2002;Ramos-Fernández and Ayala-Orozco, 2002;González-Zamora et al, 2009;Scherbaum and Estrada, 2013) in common and dominant plant families in tropical forests such as Fabaceae and Moraceae (Primack and Corlett, 2005). The diet of Ateles is mainly based on fleshy fruits and a variable proportion of leaves and blossoms (García-Orduña, 2003).…”

In order to identify the role played by plant species as a food source in the fruit election of dispersing agents (Alouatta pigra Lawrence 1933, Ateles geoffroyi Kuhl 1820 and frugivorous bats), we developed a study in dry tropical forests in Yucatan, Mexico. We recorded the fruits consumed by frugivorous bats using collectors and, for monkeys, we implemented the focal animal method. The number of fruits consumed by primates (A. pigra and A. geoffroyi) and bats were recorded, 342 and 386, respectively. It was determined that bats deposited fruits with some percentage of pulp, while monkeys contributed more with a fruits without pulp (pairwise LSD contrast p < 0.05). Among the variety of fruit species in the diet of primates, we detected that A. pigra chose mostly not an abundant species such as Enterolobium cyclocarpum Jacq. Griseb. (1860) instead of those more abundant (Manilkara zapota (L.) P. Royen (1953) and Brosimum alicastrum Sw. subsp. alicastrum C.C. Berg (1972)). The type of fruit and seed handling caused by primates would be more beneficial to seed germination than those applied by bats. Moreover, this election and fruit handling could depend on the characteristics of fruits and space-temporal availability of plant species as a food source.Keywords: Alouatta pigra, Ateles geoffroyi, seed handling, tree species, Yucatan. RESUMENCon el objetivo de examinar el papel que juegan las especies vegetales como fuentes alimenticias en la selección de frutos de agentes dispersores (Alouatta pigra, Ateles geoffroyi y murciélagos frugívoros), se realizó un estudio en selvas secas en el sureste de Yucatán, México. Se registraron los frutos consumidos por murciélagos usando colectores y, en el caso de los monos, se implementó el método de animal focal. El número de frutos consumidos registrados para ambas especies de primates y murciélagos fueron 342 y 386, respectivamente. Se determinó que los murciélagos depositaron frutos con pequeñas cantidades de pulpa, mientras que los monos contribuyeron mayormente con frutos totalmente despulpados (contrastes por pares LSD p < 0.05). Entre la variedad de especies de frutos en la dieta de los primates se detectó que A. pigra eligió frutos de las especies menos abundantes como Enterolobium cyclocarpum Jacq. Griseb. (1860) en vez de aquellas más abundantes (Manilkara zapota (L.) P. Royen (1953) y Brosimum alicastrum Sw. subsp. alicastrum C.C. Berg (1972)). El tipo de manejo de frutos y semillas causado por los primates sería más beneficioso para la germinación de las semillas que los aplicados por los murciélagos. Además, esta elección y manejo del fruto podría depender de sus características y la disponibilidad espacio-temporal de las especies de plantas como fuente de alimento.Palabras clave: Alouatta pigra, Ateles geoffroyi, manipulación de la semilla, especies arbóreas, Yucatán.

“…Species such as M. zapota and B. alicastrum are known to be amongst the most important in the diet of spider monkeys in the Mesoamerican region (González-Zamora et al, 2008), including at the only other site in the Yucatan peninsula (Punta Laguna Reserve, about 100 km southwest of the JB reserve) where feeding preferences of spider monkeys have been studied (Ramos-Fernández and Ayala-Orozco, 2003). At the JB reserve, the highest ranking species in the fruit diet of spider monkeys during our study was M. foetidissimum (subspecies gaumeri; Sapotaceae), a tree species endemic to the Yucatan peninsula (Durán et al, 2000), but this species is not reported to be used at the Punta Lagunas reserve.…”

The spider monkey, a fruit specialist and important seed dispersal agent in the Neotropics, is an endangered primate due to habitat loss, hunting and the pet trade. Spider monkeys have been the subject of a few studies in Central and South America, but little is known about the diet and ranging for this primate in southern Mexico. Here we report the results of a six-month long study (October 2010 to March 2011) of the feeding preferences and ranging patterns of the Yucatan spider monkey Ateles geoffroyi yucatanensis living in the "Ya´ax´che" reserve by the Caribbean coast in northeast Yucatan peninsula. Focal animal and scan sampling as well as GPS tracking were used to document spider monkey feeding behavior, location of food trees and ranging in the reserve. The spider monkeys used 36 species of plants (94% trees; n = 432) and six non tree morphospecies as a source of food. Six tree species accounted for ≥80% of total feeding time and for 74% of all trees used. Fruits accounted for 59% of total feeding time, followed by leaves (35%), palm piths (5%) and other plant parts (1%). Total range used by the monkeys was estimated at 43% of semievergreen rainforest habitat available (ca 40ha). Range use was not random with segments showing light, moderate and heavy use; the use of different areas of their range varied monthly and was closely linked to the spatial dispersion of the trees used for food [Current Zoology 59 (1): 125-134, 2013].

“…We hence propose the following modification. The home range of spider monkeys is actually not an infinite plane, but covers a fairly narrow and stretched area [14]. With the rules of the greedy model, we now consider targets distributed within a narrow strip, of width L and infinite in length.…”

“…The aim is to understand the effects of a random spatial distribution of fixed resources on monkey trajectories. In the experimental study [9] , monkeys used regular routes to travel between feeding sites, within a limited area of about 2 km 2 [14]. Many animals (bees [15], rodents [16], primates [17,18]) seem to rely on cognitive maps in order to navigate their environment.…”

We discuss various features of the trajectories of spider monkeys looking for food in a tropical forest, as observed recently in an extensive in situ study. Some of the features observed can be interpreted as the result of social interactions. In addition, a simple model of deterministic walk in a random environment reproduces the observed angular correlations between successive steps, and in some cases, the emergence of Lévy distributions for the length of the steps.
