We studied the geographic distribution of the endangered black howler monkey, Alouatta pigra, in its southeastern range in eastern Guatemala along its putative contact zone with the mantled howler monkey, A. palliata. A distributional survey of both species was conducted through direct observations and interviews, and the data analyzed with GIS to detect potentially limiting geographic and ecol...
متن کاملMolecular systematics and biogeography of the Neotropical monkey genus, Alouatta.
We take advantage of the broad distribution of howler monkeys from Mexico to Argentina to provide a historical biogeographical analysis on a regional scale that encompasses the entire Neotropics. The phylogenetic relationships among 9 of the 10 recognized Alouatta species were inferred using three mitochondrial and two nuclear genes. The nuclear gene regions provided no phylogenetic resolution ...
متن کاملSeed Dispersal Patterns in Two Closely Related Howler Monkey Species (alouatta Palliata and A. Pigra): a Preliminary Report of Differences in Fruit Consumption, Traveling Behavior, and Associated Dung Beetle Assemblages
Two-phased seed dispersal by primates and dung beetles is crucial for tropical rainforest regeneration. Two species of howler monkey exist in the tropical rainforests of southern Mexico: the mantled howler monkey (Alouatta palliata), and the black howler monkey (A. pigra). Differences between these species in foraging and traveling behavior, as well as associated dung beetle assemblages, may in...
متن کاملBiochemical and hematological evaluations of black howler monkeys (Alouatta pigra) in highly degraded landscapes in Mexico.
BACKGROUND Loss and fragmentation of Neotropical primates' habitat can alter the health and individual adaptation. Physiological parameters reflect health status and individuals responses to the habitat conditions. METHODS We captured six wild adult females and six adult males of Alouatta pigra to evaluate their physical condition (body mass, respiratory and heart rate, and rectal temperature...
متن کاملThe function of loud calls in black howler monkeys (Alouatta pigra): food, mate, or infant defense?
Loud calling (i.e., howling) is the single most distinctive behavioral attribute of the social system of howler monkeys (Alouatta spp.), yet no general consensus exists regarding its main function. During a 28-month study of five groups of black howler monkeys (Alouatta pigra) at Palenque National Park, Mexico, we examined whether howling mainly functioned in the defense of food resources, mate...
