Abstract A population of black and gold howler monkeys ( Alouatta caraya ) living near the southern limit its distribution in a semideciduous forest located northern Argentina was studied 2003 to evaluate possible effects habitat fragmentation – owing logging on density social organization within it. Aerial photographs taken 1982, 1992, 2001 were used compare maps vegetation. These changes area covered by fragments. From March June 2003, 10‐day monthly surveys howlers made each fragment....
Abstract Behavioral and demographic factors such as group size, social structure, dispersal patterns, mating systems affect male reproductive success. In the present study, we analyze relationship between genetic relatedness of adult males offspring paternity in one population Alouatta caraya inhabiting a continuous forest Northern Argentina. After 14 months behavioral studies genotyping 11 microsatellites, found that dominant or central achieved greater success fathered all conceived during...
Primates play an important role in ecosystem functioning and offer critical insights into human evolution, biology, behavior, emerging infectious diseases. There are 26 primate species the Atlantic Forests of South America, 19 them endemic. We compiled a dataset 5,472 georeferenced locations native 1 introduced species, as hybrids genera Callithrix Alouatta. The includes 700 communities, 8,121 single occurrences 714 estimates population sizes, covering most natural forest types tropical...
In South America, yellow fever (YF) is an established infectious disease that has been identified outside of its traditional endemic areas, affecting human and nonhuman primate (NHP) populations. the epidemics occurred in Argentina between 2007-2009, several outbreaks humans howler monkeys (Alouatta spp) were reported, highlighting importance this context conservation medicine public health policies. Considering lack information about YF dynamics New World NHP, our main goal was to apply...
The black and gold howler monkey (Alouatta caraya) is a neotropical primate threatened by habitat loss capture for illegal trade in Argentina. Using multilocus microsatellite genotypes from 178 A. caraya individuals sampled 15 localities Argentina, we built genotype reference database (GRDB). Bayesian assignment methods applied to the GRDB allowed us correctly re-assign 73% of their true location origin 93.3% cluster origin. We used assign 22 confiscated (17 which were reintroduced), 3...
Black-and-gold howler monkeys Alouatta caraya, are arboreal primates, inhabitants of Neotropical forests, highly susceptible to the yellow fever virus, considered early 'sentinels' outbreaks, and thus, major epidemiological importance. Currently, anthropogenic habitat loss modifications threatens their survival. Habitat modification can prevent, reduce or change dispersal behavior, which, in turn, may influence patterns gene flow. We explored past contemporary levels genetic diversity,...
The brown howler monkey ( Alouatta guariba ) is endemic to the Atlantic Forest of eastern Brazil and northeastern Argentina, threatened by extinction due habitat loss fragmentation, hunting. Its reduced isolated populations dramatically decreased suffered local extinctions after recent yellow fever outbreaks, recommending species risk uplist from Vulnerable Endangered. In Brazil, occurs along eight states in sparse populations, including some large protected areas, being uplisted Following...
As road infrastructure networks rapidly expand globally, especially in the tropics, previously continuous habitats are being fragmented, resulting more frequent wildlife-vehicle collisions (WVC). Primates widespread throughout many sub-/tropical countries, and as their they increasingly at risk of WVC. We created Global Primate Roadkill Database (GPRD), largest available standardized database primate roadkill incidents. obtained data from published papers, un-published citizen science...
Abstract We identified 11 polymorphic microsatellite markers for Alouatta caraya . Three were isolated from an enriched genomic library of A. (AC14, AC17, AC45), five previously described in Homo sapiens (TGMS1, TGMS2, D5S117, D8S165, D17S804), and three Lagothix lagotricha (1110, 1118, 157). Forty‐eight individuals one Argentinean population genotyped, yielding heterozygosity values between 0.146 0.792. These provide exclusion power 0.922 when neither parent is known (0.992 known) are...
Many aspects of the ecology, evolution and social behavior wild-living primates remain un-explored require further investigation. While long-term field studies are crucial for addressing conservation concerns many primates' species, acquiring necessary data is often challenging, due to difficulties in locating study groups. Radio-telemetry has significantly facilitated other animals living tropical forests. However, there important practical challenges process capturing releasing after...
Conservation genetics is the use of to understand and mitigate threats caused by anthropogenic activities, including habitat loss fragmentation, wildlife trafficking, emerging diseases. In this review, we discuss role primate conservation in development effective strategies, emphasizing importance maintaining genetic diversity enhance adaptive potential prevent extinction. First, studies various species that exemplify how data have been instrumental accurately assessing threat levels,...
The brown howler monkey ( Alouatta guariba clamitans) is endemic to South America's Atlantic Forest, with a small population extending into the northern portion of Misiones province in northeastern Argentina. In 2012, species was classified as Critically Endangered Argentina due its highly restricted distribution, low density and dramatic declines from recent Yellow Fever outbreaks. March 2013, we organized an international workshop evaluate status conduct threat analysis. We developed...

Abstract Competition is a major aspect of the ecology insect communities exploiting ephemeral and fragmented resources. We analysed effect intraspecific (single species culture) interspecific (mixed competition on larval viability, developmental time wing length in cactophilic Drosophila buzzatii koepferae (Diptera: Drosophilidae) reared cultured media prepared with fermenting tissues three common natural cactus hosts nature at different densities. Our results show that all traits measured...

Capuchin monkeys (Sapajus nigritus cucullatus) are the most omnivorous primates of New World. However, forest fragmentation and degradation may limit resources availability. This in turn can act synergistically with other factors, such as severe weather conditions potentially causing changes spatial distribution, behavior, diet. During field observations capuchin we recorded use bamboo patches refuge sites supplementary food sources. behavior was observed December 2021 fragmented...
