Comportamiento alimentario de monos aulladores negros (Alouatta pigra Lawrence, Cebidae) en hábitat fragmentado en Balancán, Tabasco, México
This report is based on the feeding behavior of one black howler monkey troop (Alouatta pigra). Observations were made during an annual cycle (February 2002 to January 2003) in a highly fragmented habitat (0,164 ha) in the Leona Vicario ranch, Balancan, Tabasco, Mexico.

| description | This report is based on the feeding behavior of one black howler monkey troop (Alouatta pigra). Observations were made during an annual cycle (February 2002 to January 2003) in a highly fragmented habitat (0,164 ha) in the Leona Vicario ranch, Balancan, Tabasco, Mexico. The present study is the first systematic report for the state of Tabasco on the diet of this primate specie. By means of the Focal Animal method, behavioral observations of the activities of the troop (n=9, 3 AM, 2 AF, 2 J, 2 I) were recorded (n = 499 h), of which 19.6 % (96 h 55 min) were recorded developing feeding behavior. In the study area we recorded the consumption of 15 spp. (55.5 %) of a total of 27 plants species in the site. The number of species used per month varied from 5 to 12 (mean = nine species). The Young leaves and the mature fruits were the main vegetal parts consumed by the howlers (70.8 % and 11.4 % respectively). Between the different species consumed by the howlers, only few were preferred by the troop (X2= 25060, p>>0.001, gl =14) and these species had low densities in the study site (vgr. Andira inermis with 0,007 ind/ha). Under these disturbance conditions, howler’s consumption on different plant parts throughout the year shows us a high nutritional flexibility. This strategy allows the black howler monkeys to survive in the study site in the short term; nevertheless, it is very important to investigate the consequences population level in the future. |

Se informa sobre el comportamiento alimentario del mono aullador negro (Alouatta pigra Lawrence) durante un ciclo anual (Febrero 2002 a Enero 2003) en un remanente boscoso de 0.164 ha rodeado de potrero en la Ranchería Leona Vicario, Balancán, Tabasco, México. La presente investigación se constituye como el primer estudio sistemático para el estado de Tabasco sobre la dieta de esta especie. Mediante el método Animal Focal, se registraron observaciones conductuales (n= 499 h) de las actividades de una tropa de A. pigra (n= 9; 3 MA, 2 HA, 2 J, 2 In), de las cuales el 19.6 % (96 h 55 min) fueron dedicadas a la alimentación. En el área de estudio se registró el consumo de 15 spp. (55.5 %) de un total de 27 especies de plantas presentes en el área de estudio. El número de especies usadas por mes variaron desde 5 a 12 con un promedio de 9 especies. Las hojas jóvenes y los frutos maduros fueron las partes vegetales principales en la dieta de los monos aulladores y los porcentajes de uso fueron 70.8 % y 11.4 % respectivamente. Entre las diferentes especies de plantas consumidas por los aulladores, se mostró preferencia (X2= 25060, p>0.001, gl. =14) por algunas que se presentaban poco abundantes en el sitio de estudio (p.e. Andira inermes con 0.007 ind/ha). Bajo estas condiciones de perturbación, el consumo de diferentes especies vegetales, así como de sus diferentes partes a lo largo del año indica que los monos aulladores negros poseen una gran flexibilidad alimenticia que les ha permitido sobrevivir en el área de estudio. Sin embargo, se presenta como un reto el investigar la viabilidad poblacional de la especie en años futuros.
