“…Therefore, our knowledge of within-population variability is quite limited because only a few researchers have monitored more than a single group in the same forest (Larose 1996 ; Ostro et al 1999a ;Arrowood et al 2003 ;Bridgett 2006 ;Kowalewski 2007 ;Hopkins 2008 ;Agostini 2009 ;Gómez-Posada and Londoño 2012 ).

“…Howler monkeys ( Alouatta spp.) are well known for their ecological flexibility and tolerance to habitat degradation [Arroyo‐Rodríguez & Dias, ; Bicca‐Marques, ; Gómez‐Posada & Londoño, ]. This has led several authors to conclude that seed dispersal services by Alouatta may be playing a key role in plant regeneration in habitats in which other frugivorous animals have declined or disappeared [reviewed by Arroyo‐Rodríguez et al, in press].…”

Recent evidence has shown that primates worldwide use agroecosystems as temporary or permanent habitats. Detailed information on how these primates are using these systems is scant, and yet their role as seed dispersers is often implied. The main objective of this study was to compare the activity, foraging patterns and seed dispersal role of black howler monkeys (Alouatta pigra) inhabiting shaded cocoa plantations and rainforest in southern Chiapas, Mexico. We gathered data on three monkey groups living in shaded cocoa plantations and three groups living in rainforest, using focal sampling, and collecting fecal samples. General activity and foraging patterns were similar in both habitats, with the exception that monkeys in the cocoa habitat spent more time feeding on petioles. Monkeys in shaded cocoa plantations dispersed 51,369 seeds (4% were seeds ≥3 mm width) of 16 plant species. Monkeys in the rainforest dispersed 6,536 seeds (78% were seeds ≥3 mm width) of 13 plant species. Our data suggest that the difference between habitats in the proportion of large versus small seeds dispersed reflects differences in fruit species abundance and availability in cocoa versus forest. Mean seed dispersal distances were statistically similar in both habitats (cocoa = 149 m, forest = 86 m). We conclude that the studied cocoa plantations provide all elements necessary to constitute a long-term permanent habitat for black howler monkeys. In turn, howler monkeys living in these plantations are able to maintain their functional role as seed dispersers for those native tree and liana species present within their areas of activities.

Since the fi rst long-term fi eld study of mantled howler monkeys carried out by Clarence R. Carpenter on Barro Colorado Island about 80 years ago, howler movement patterns and range use have been studied in several species and study sites throughout Mexico, Central, and South America. Howler monkeys often use small home ranges (<30 ha) and travel short distances each day (<1,000 m) compared with other atelines. Home range size, day range length, and patterns of use of space may vary both within-and between-species in response to differences in forest structure, patterns of resource distribution and phenology, the area of habitat available, group size, and population density. Within-species variability has been shown to increase with increasing sample size. In addition, howlers present a pattern of repetitive use of a limited number of routes to travel between feeding and V. B. Fortes
