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...
Este trabalho objetivou a análise do histórico (1937-2008) de ocorrência incêndios florestais Parque Nacional Itatiaia (PNI), primeiro parque Brasil. Para isso, foi realizado um levantamento informações no PNI, sobre o número total incêndios, extensão das áreas queimadas, os meses maior incidência, relação fogo ao período seca, fauna e flora atingidas, agentes causadores, as principais causas perícias dos incêndios. Foram identificados 323 (1937-2008). Apenas nos últimos sete anos foram...
Background and AimsThe period between the beginning of anthesis flower senescence modulates transport pollen by pollinators among conspecific flowers, its length may therefore influence reproductive success. This study evaluated whether floral longevity favours removal from anthers over fecundity (seed set) in an ornithophilous species that does not undergo limitation.

The anthropogenic fire is a major threat to the high altitude grasslands of Itatiaia National Park - INP, where over 70% cases in this ecosystem state Rio de Janeiro. However, their impacts are still unknown. Understand processes associated with regeneration after suggested by Management Plan INP. objective study was evaluate floristic composition and structure plant community four sites located at 2500 m different historical fires (1988, 2001, 2007 2010). It studied area 1600 m² divided...
Leucism is the lack or reduction in pigmentation most parts of body, but not eyes and body extremities. It extremely rare primates has never been reported for Callithrix , a genus endemic to Brazil. We searched individuals jacchus C. penicillata with anomalies systematic survey three protected areas Atlantic Forest, within museum collections Brazil, opportunistically during field studies. Since 2008, we have recorded 8 leucism small urban periurban forest patches. Four were from native...
A utilização de armadilhas fotográficas na amostragem longa duração mamíferos terrestres pode fornecer informações precisas sobre o estado conservação uma área. No Estado do Rio Janeiro, apenas um estudo teve pouco mais 250 armadilhas-dias, esforço amostral mínimo para se obter número significativo espécies. Apenas outros dois estudos sudeste Brasil realizaram comparável ao realizado aqui no Parque Nacional Itatiaia (PNI) e da Serra dos Órgãos (PARNASO). De outubro 2010 a setembro 2012,...
Abstract is a rodent from the Brazilian Atlantic Forest with cryptic behavior that hinders collection of information regarding its ecology. On October 2014, we observed an individual
Tayra ( Eira barbara ) has been reported across its geographic range as having little natural variation in coat color, including cases of leucism. This mustelidae, the ecology which is still unknown, can occur from sea level up to 2,400 m altitude, though it rare above 1,200 m. We report two records E. . The first was obtained 2,500 high-altitude grasslands Itatiaia National Park. highest altitude ever recorded for an observation this species Brazil. second record albinic tayra nature....
To evaluate the habitat loss due to climatic changes and their effect on Callithrix diversity in next few decades, present study reported resilience of Atlantic Rainforest primate genus under perspective forecasted South America quick-pace changing environmental policies Brazil.The used present-day distribution marmosets several bioclimatic layers model project suitability for all species recent decades.The presented results are far from being optimistic.Almost except C. jacchus will...
The occurrence of Alouatta guariba clamitans in the Itatiaia National Park (PNI) are considered rare. For over 70 years an epizootic outbreak yellow fever almost caused local extinction this species and since then only one record by direct observation was obtained. In study, records were obtained a group four adults, male three females, infant forest environment (ca. 1200m). One females presented anomaly coloration, characterized as leucism. A solitary adult held high altitude grasslands...
The occurrence of the Buffy-tufted-ear Marmoset Callithrix aurita in Itatiaia National Park (INP) is considered rare. For over 50 years, there were no new records species within PNI. In this study, after three years surveys PNI (432h), record was obtained. Two other observed: Black-horned capuchin Sapajus nigritus (n=10) and Black-fronted Titi Monkey Callicebus nigrifrons (n=12). However, 2015, when already completed, I obtained two occasional C. aurita. first as May surroundings addition, a...
Tropical high-altitude vegetation is unique due to susceptibility severe weather conditions in relation lower formations, and by the peculiarity of its flora with many relictual components. Studies on plant-pollinator interactions rocky outcrops forests Atlantic Forest are scarce, but compilation information allows us identify some patterns: low frequency visits, high floral longevity generalized pollination system. In tropical mountain ecosystems, degree generalization systems functional...

CONFIRMATION OF THE OCCURRENCE NORTHERN MURIQUI (PRIMATES, ATELIDAE) IN ITATIAIA NATIONAK PARK, RIO DE JANEIRO STATE, SOUTHEAST BRAZIL The occurrence of Brachyteles in Itatiaia National Park (PNI) has been known for over 70 years. However, species identification is doubtful due to taxonomic divergence publications and the lack photographic records. In this work, we present records that confirm definitively presence hypoxanthus PNI. Among our findings record higher altitude (1.823m) two...
A fragmentação, caça furtiva e invasão de espécies exóticas na Mata Atlântica são fatores importantes para a perda da biodiversidade mamíferos médio grande porte neste bioma. Reserva do Patrimônio Natural Alto-Montana (RPPN Alto-Montana), dominada pela Floresta Ombrófila Mista, caracterizada presença Araucaria angustifolia (Pinales, Araucariaceae), se localiza Serra Mantiqueira, que é considerada um dos lugares insubstituíveis mundial. Utilizamos oito armadilhas fotográficas, 2013 2016, com...
Abstract Biotic interactions related to the consumption of floral nectar and fruits as food resource by birds promoting plant pollination dispersal, are essential for forest ecosystem functioning. The daily interaction with Acnistus arborescens (Solanaceae), a shrub-tree, was studied in Itatiaia National Park its surroundings. Reproductive phenology monthly monitored eighteen individuals 2015. During flowering (August November) fruiting (September December) birds-plant studied. Flowers were...
Carnivores typically exhibit cryptic behavior, which makes it difficult to study the ecology of species in this group. Camera trap bycatch can be a valuable source important opportunistic records. In short communication, we present rare records carnivores southern Brazil. The first record was tayra (Mustelidae) with anomalous coloration known as leucism. Other were possible attempted predation event by two free-ranging dogs on lowland tapir (Perissodactyla, Tapiridae), threatened species....

Stevia camporum (Asteraceae) is a threatened and endemic geophyte of the rocky outcrop vegetation in high altitude grasslands on top Itatiaia massif. This locally abundant plant, which establishes itself preferentially mats dominated by pioneer species such as mosses (Campylopus pilifer) vascular plants Fernseea itatiaiae Barbacenia gounelleana. With very distinctive morphology, these nurse may differently influence dynamics S. camporum. These relations were previously studied for two years...
