Abstract Two yellow fever outbreaks (YFOs) ocurred in northeastern Argentina between November 2007 and October 2008, seriously affecting populations of two howler monkey species: the brown Alouatta guariba clamitans black caraya . Both howlers live syntopically El Piñalito Provincial Park, Misiones, where four groups (36 individuals) were studied since January 2005. The first dead found on 20, Piñalito. Systematic searches 14 within area (12 from study neighboring groups), with only young...
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...
Abstract According to the principle of competitive exclusion, niche differentiation allows stable coexistence closely related species. We analyzed dietary profile and diversity, overlap between syntopic brown howlers (BR; Alouatta guariba clamitans ) black gold (BLG; A. caraya in Atlantic Forest NE Argentina, with objective evaluating degree trophic potential interspecific competition for food. During 12 months, we collected data on feeding behavior two groups each howler species using scan...
Ecologically similar and closely related species in sympatry may differ their activity patterns to avoid interspecific contest competition. We here present the 1st study aimed at evaluating effects of seasonality, group size, presence a congener on 2 syntopic howler monkeys, brown (Alouatta guariba clamitans) black-and-gold (A. caraya), northeastern Argentina. During 12 months, we collected data groups each characterized by different sizes degrees home-range overlap, together with food...
Semelparous woody bamboos flower fairly synchronously and in clocklike fashion after many years, providing abundant nutritious seeds. However, this resource is ephemeral, localized, unpredictable from the perspective of birds that feed on those Birds specializing bamboo seeds track food source are nomadic. We recorded Temminck's Seedeater (Sporophila falcirostris) at 29 localities Buffy-fronted (S. frontalis) 23 Argentina, Paraguay, southeastern Brazil. In these species, nomadism...
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 Vocalizations used for long‐range communication must disperse without significant structural changes to be decoded by receivers. The acoustic adaptation hypothesis (AAH) holds that, since signals are influenced the habitat in which they disperse, sounds will possess specific characteristics diminish sound degradation. Additionally, vocalizations can also genetics, anatomy, and/or cultural aspects. Here, we tested AAH through quantitative comparisons of roars four allopatric...
Species limits in the Poospiza nigrorufa/whitii complex are not well understood. Three taxa formally described as species now considered subspecies (nigrorufa, whitii and wagneri) of a widespread species. The heavier nigrorufa has longer bill, tarsus wings, is slightly dimorphic with males showing tawny rufous throat, breast flanks, brownish grey upper parts slate tinge, while females differ orange tinge ventral more olivaceous parts; inhabits shrubby open areas wetlands reeds bulrushes...
Argentina lies within the southernmost distributional range of five neotropical primates, brown howler monkey Alouatta guariba, black-and-gold caraya, black-horned capuchin Sapajus nigritus, Azara’s cay, and owl Aotus azarae; first three which are globally threatened. These species occupy different ecoregions: Alto Paraná Atlantic forest, Araucaria moist humid Chaco, Southern Cone Mesopotamian savanna, Ffooded Andean Yungas. The recently approved National Primate Conservation Plan calls for...
