    Abstract

    Males may share access to fertilizable females (polygynandry)in one environment while, under conditions, polygynous (one-male or 'harem') mating is the norm. However, few studies in mammals have empirically investigated the factors predicting when males will coexist in bisexual reproductive units rather than live in one-male associations with females. We examined patterns with male group membership in a population of black howler monkeys Alouatta pigra residing in two habitats (deciduous and riparian)of a tropical moist forest environment in Belize, Central America. Using general linear and logistic regression modeling, we evaluated nine variables as possible predictors of male residence patterns (one-male groups or multimale groups. Our results suggest that adult sex ratio and group size are the best predictors of male residence patterns in both habitats. Our findings provide empirical support for theoretical expectations that male reproductive strategies will be a function of habitat related demographic patterns and the subsequently varying potential of males to monopolize females in heterogeneous regimes. This study may have important implications for our understanding of features of mammalian societies in which males compete directly for access to females.
