Mating promiscuity and reproductive tactics in female black and gold howler monkeys (Alouatta Caraya) inhabiting an island on the Paraná river, Argentina
(Wiley-liss, Div John Wiley & Sons Inc, 2010-08)
In several primate species, females mate promiscuously and several adult males peacefully co-reside in the same social group. We investigated female mating behavior in two neighboring multimale–multifemale groups of Alouatta ...
Births in Wild Black and Gold Howler Monkeys (Alouatta caraya) in Northern Argentina
(Wiley-liss, Inc, 2009-03)
Previous studies on births in nonhuman primates suggest that births are expected to occur at night to avoid predators. Here, we describe birth-related behaviors in wild black and gold howler monkeys, Alouatta caraya and ...
Diagnóstico histopatológico de entamoebiosis en un primate en cautiverio (Alouatta caraya)
(Universidad Nacional del Nordeste, 2010)
Using species distribution modeling to assess factors that determine the distribution of two parapatric howlers (Alouatta spp.) in South America
(Springer, 2015-02)
We used the ecological niche model MaxEnt to predict the potential distribution of the brown howler monkey (Alouatta guariba clamitans) and the black-and-gold howler monkey (Alouatta caraya) in South America, as well as ...
Differential distribution of sperm subpopulations and incidence of pleiomorphisms in ejaculates of captive howling monkeys (Alouatta caraya)
(Springer, 2013-10-01)
The aim of this study was to develop an objective method to determine the incidence of pleiomorphisms and its influence on the distribution of sperm morphometric subpopulations in ejaculates of howling monkeys (Alouatta ...
Determinants of daily path length in black and gold howler monkeys (Alouatta caraya) in northeastern Argentina
(Wiley-liss, Div John Wiley & Sons Inc, 2016-08)
Models used to explain the social organization of primates suggest that variation in daily path length (DPL) is a response to variation in resource distribution and the intensity of intragroup feeding competition. However, ...
How Do Demographic and Social Factors Influence Parent-Offspring Conflict? The Case of Wild Black and Gold Howler Monkeys (Alouatta Caraya)
(Wiley, 2015-04)
In this study, we examined the influence of demography and social context on mother-offspring conflict in wild black and gold howler monkeys (Alouatta caraya) inhabiting two nearby sites in northern Argentina, one comprising ...
Genetic Consequences of Habitat Fragmentation in Black-and-Gold Howler (Alouatta caraya) Populations from Northern Argentina
(Springer, 2010-10)
Human-induced habitat fragmentation might seriously affect behavioural patterns and the survival of species whose ecological requirements strongly depend on specific environmental conditions. We compared the genetic structure ...
El conflicto madre-infante en el mono aullador negro y dorado (Alouatta caraya) y su comparación en dos sitios del noreste
(2014-03-27)
Se examinó la relación entre intensidad y duración del conflicto madre-infante y características ecológicas y de historia de vida en monos aulladores negros y dorados (Alouatta caraya) en dos bosques del noreste argentino. ...
