Hunting is an ancient human behavior, which likely became complex and efficient gradually through time. We present data from a bibliographic survey (qualitative) and field sampling (quantitative) of primate hunting in Northeastern Brazil. We evaluated hunting threats faced by 14 primate species native to the States of Bahia and Sergipe (three Criti...
Caracterizar a estrutura do habitat, identificando a funcionalidade de espécies arbóreas, é uma estratégia importante para auxiliar programas de manejo. Este estudo objetivou caracterizar a estrutura do habitat, identificar a composição ecológica e o tipo de síndrome de dispersão das árvores em fragmentos habitados pelo ameaçado de extinção Callice...
Despite their importance to conservation strategies, baseline data on species distribution and abundance are lacking for many primates. Discovered 30 years ago, the blond titi (Callicebus barbarabrownae) is considered Critically Endangered. The first assessments in 2004-2006 sampled 126, 1-km radius areas using interviews, sightings, and playing ba...
In 2011, a distinct but unnamed form of titi, Plecturocebus, was rediscovered in the Chapada dos Parecis, a plateau in the southern extreme of the Brazilian state of Rondônia. Here we describe it as a new species based on an analysis of morphological and molecular traits. It can be distinguished from all other species of the genus Plecturocebus by...
Xenarthrans—anteaters, sloths, and armadillos—have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with domestic dogs, these species have been threatened locally, regionally, or even across...
Primates play an important role in ecosystem functioning and offer critical insights into human evolution, biology, behavior, and emerging infectious diseases. There are 26 primate species in the Atlantic Forests of South America, 19 of them endemic. We compiled a dataset of 5,472 georeferenced locations of 26 native and 1 introduced primate specie...
Primates of the Lago Piratuba Biological Reserve, state of Amapá, Brazil: occurrence, conflicts and threats. Although the Lake Piratuba Biological Reserve (RBLP) is a strictly protected area, there are pressures and threats that might compromise the conservation of its biota. In this work, we evaluate the presence of primates in the RBLP lack of in...
The Brazilian Caatinga are the most densely populated semiarid zone of the planet. Despite this, the local biota and ecological processes are still poorly known. The biota of the Brazilian state of Sergipe is also poorly known, although half of which is part of the Caatinga, currently with about 10% of forest remnants. In order to better understand...
Este estudo teve o objetivo de quantificar e caracterizar os fragmentos de floresta no baixo rio São Francisco, porção pertencente ao Estado de Sergipe, avaliando-os quanto ao tamanho, a forma e distribuição sob o ponto de vista da conservação. Foram utilizadas imagens do satélite Landsat 5 (TM) para identificação e mapeamento dos fragmentos de mat...
This is my master degree dissertation which contains information about mapping, satelite image segmentation, geoprocess, land scape ecology and field expedition at Caatinga and Atlantic Forestry. Also includes information about Callicebus coimbrai biogeography at São Francisco Watersheld area.
RESUMO – A Reserva Biológica do Lago Piratuba foi criada em 1980 como uma área isenta de ocupações humanas e sem uso de seus recursos naturais. No entanto, já existiam populações tradicionais que ocupavam e utilizavam a área, em vários pontos no interior dos limites propostos. Diante dos conflitos de uso e ocupação em razão da categoria da unidade...
The Brazilian Northeast is dominated by the Caatinga, a xeric scrub forest characterized by “semiarid” climatic conditions, with annual precipitation often below 600 mm, and an unpredictable rainy season. North of 13ºS, the Atlantic Forest forms a narrow coastal strip, of only a few dozen kilometers in width, with a relatively humid climate. Both b...
Coimbra-Filho's titi monkey, Callicebus coimbrai Kobayashi and Langguth, 1999, appears to be endemic to the northern Atlantic Forest, south of the lower São Francisco River in east of the state of Sergipe and north-east of the state of Bahia. This study presents 13 new records of the occurrence of the species in the São Francisco and Japaratuba bas...
Barbara Brown's titi monkey, Callicebus barbarabrownae Hershkovitz, 1990, appears to be endemic to the Caatinga of northern Bahia and western Sergipe, although few data are available for the northernmost portion of its range. The present study presents seven new occurrence records of the species, in the São Francisco basin of northern Sergipe, exte...
Coimbra-Filho’s titi monkey (Callicebus coimbrai Kobayashi & Langguth, 1999) has been
considered to endangered ever since its discovery in northern Sergipe due to its restricted
geographic range (northern coastal Bahia and neighboring areas of Sergipe) and extensive
habitat fragmentation. The monitoring of C. coimbrai populations and the evaluat...
Preliminary evaluation of habitat use and playback response in Callicebus coimbrai Kobayashi & Langguth, 1999 and Callithrix jacchus (Linnaeus, 1758) at Mata do Junco Wildlife Refuge, Sergipe, Brazil. Habitat use and playback response was evaluated in two primate species (Callicebus coimbrai Kobayashi & Langguth, 1999 – titi monkey and Callithrix j...
A Mata Atlântica brasileira é um “hotspot” de biodiversidade e endemismo, tendo sofrido um extensivo desmatamento. Impactos antrópicos são especialmente intensos no extremo setentrional deste bioma. Entretanto, poucos dados são disponíveis sobre a fauna local da maioria das áreas. Trabalhos de campo recentes na Fazenda Trapsa, uma propriedade priva...
