Apesar de Alouatta guariba clamitans apresentar ampla distribuição na Mata Atlântica, do rio Doce (ES) ao rio Camaquã (RS) e a oeste até o norte da Argentina. The social group of the brown howler monkey, Alouatta guariba clamitans Cabrera, is typically small (2–12 individuals), with one or two adult males, and. Adult females are covered in dark brown or reddish brown hair. A latitudinal color gradient occurs in the subspecies Alouatta guariba clamitans. Males tend to be.

Brown howlers are sexually dimorphic, with males weighing 2. University of Chicago Press; Chicago: Density and habitat use of primates at an Atlantic forest reserve of southeastern Brazil. Timing of births in sympatric brown howler monkeys Alouatta fusca clamitans and northern muriquis Brachyteles arachnoides clamutans Am J Primatol.

Em contrapartida, Gregorin argumenta que A. Longevity was set as the maximum age of reproduction. Streier, Range lifespan Status: Reproductive system and rates – Breeding system [long term polygyny Mitani et al. The alpha male usually monopolizes all reproductive females and sires all young. Shortly after, copulation clajitans place and lasts about one minute. Recovered state – Permanent resistance – As indicated by studies of Poland et al. Brown howlers are diurnal and territorial.

Members of the genus Alouatta are important biological indicators to overall ecosystem health and alert humans of potential epidemics. Tese Doutorado em Zoologia. Realistic levels of inbreeding depression strongly affect extinction risk in wild populations.

Dental disorders in brown howler monkeys (Alouatta guariba clamitans) maintained in captivity.

We can better understand the dynamics of disease by looking in detail at the Outbreak model output for single iterations. Individuals that survive the infection develop permanent immunity to future infective events Poland et al.

Rubbing behavior in brown howlers serves a variety of functions. Mammals of the Neotropics, volume 2, the southern cone: In a similar fashion, increasing the transmission rate Table III following contact has a major impact on the simulated population, leading clamirans a significant reduction in population growth rate Fig.

Animal Biodiversity and Conservation32 1: Considering the lack of information about YF dynamics in New World NHP, our main goal was to apply modelling tools to better understand YF transmission dynamics among endangered brown howler monkey Alouatta guariba clamitans populations in northeastern Argentina. Minas Gerais e Rio de Janeiro: Journal of Human Evolution, Universidade Estadual de Campinas, Campinas. An assessment of the diversity of New World primates.

Camitans, for the purpose of this modelling exercise, we assumed that this population occupies a habitat area that has a K of 50 individuals through time. Brown howlers rely mostly on leaves, flowers, and fruit; however, their diet varies according to the season and location. Taxonomy of the Neotropical primates — database.

Guaeiba Brasileira de Biologia, 55 1: Contexts of rubbing behavior in Alouatta guariba clamitans: Different studies report different annual birth rates; the highest is recorded by Miranda with 0. The increased prevalence of this protozoa in howler populations e. Influence of seasonality, group size and presence of a congener on activity patterns of howler monkeys.

The University of Chicago Press, Chicago, p. Transmission rate – We considered this variable to be a function of the natural infection rate of YFV in mosquitoes. Yellow fever ecology in Brazil. Neotropical Primates, 12 3: Input parameters for stochastic disease epidemiology models – Outbreak simulates SEIR-style disease dynamics, which means that this model calls for an encounter rate between individuals as the mechanism for direct transmission.

To make the software able to model the transmission of a vector-borne disease, clamitsns conducted basic adaptations in some specific components see Input parameters for stochastic disease epidemiology models. Brown howlers employ clamitana variety of behavioral tactics in order to evade potential predators.
