1. Population ecology of Chaetophractus vellerosus: the first report for an armadillo in South America
ABSTRACT The aim of this work was to obtain the first estimates of survival rates (S), capture probability (p) and life expectancy for armadillos in South America by analyzing capture-mark-recapture data obtained from a population of Chaetophractus vellerosus (Gray, 1865) located in Magdalena, Buenos Aires, Argentina. From June 2006 to June 2011, we conducte

2. Determinants of capture-recapture success: an evaluation of trapping methods to estimate population and community parameters for Atlantic forest small mammals
ABSTRACT Efficiently obtaining high-quality data on animal populations and communities is paramount for ecological and conservation studies. In many instances these data come from live-trapping, the success of which depends on various factors, such as the interaction between the trap's mechanisms and the morphological or ecological characteristics of the ani

3. Determinantes ecológicos do risco de extinção: abundância local, amplitude de nicho, capacidade de dispersão e a resposta das espécies de pequenos mamíferos à fragmentação florestal no Planalto Atlântico Paulista / Ecological determinants of extinction risk: local abundance, niche breadth, dispersal ability and response of small mammals to forest fragmentation at the Atlantic Plateau of São Paulo
Anthropogenic disturbances, particularly habitat loss and fragmentation, are considered the main causes of the increased extinction rates observed in the last decades. Since the risk of extinction is extremely variable among species, the ecological determinants of the chance of extinction have been in the center of the debates in the ecological literature. E

4. Eliminação de parâmetros perturbadores em um modelo de captura-recaptura
O processo de captura-recaptura, amplamente utilizado na estimação do número de elementos de uma população de animais, é também aplicado a outras áreas do conhecimento como Epidemiologia, Linguística, Con_abilidade de Software, Ecologia, entre outras. Uma das primeiras aplicações deste método foi feita por Laplace em 1783, com o objetivo de estim

5. Artificial nests as an alternative to studies of arboreal small mammal populations: a five-year study in the Atlantic Forest, Brazil
Despite the great diversity of Brazilian Atlantic forest small mammals, natural history of most species is unknown due to their cryptic and nocturnal habits, but also due to the inadequacy of methods to capture some species, especially those of arboreal habits. A new technique, based on the use of artificial nests (AN) to record arboreal marsupials, is prese

6. Tamaño poblacional, uso del hábitat y relaciones interespecíficas de Agalychnis spurrelli (anura: hylidae) en un bosque húmedo tropical remanente del noroccidente de Ecuador
Throughout 2006 and 2007, at a small swamp in San Francisco del Cabo, northwestern Ecuador, monthly field expeditions were done to monitor a population of the leaf frog Agalychnis spurrelli with the following aims: (1) to determine population size and annual fluctuation; (2) to determine spatial distributional patterns and microhabitat resource partitioning;

7. Estimation of underreporting of live births by the capture-recapture / Estimação de sub-registro de nascidos vivos pelo método de captura e recaptura
Introduction Capture-recapture method has been used in Epidemiology since the middle of twentieth century and from the 1990s on, huge number of publications about applying and developing the method on this area have been noted. Underreporting of vital events is still a drawback for the direct calculation of health indicators like fertility and infant mortali

8. Eliminação de parâmetros perturbadores na estimação de tamanhos populacionais
In this study, we used the capture-recapture procedure to estimate the size of a closed population. We analysed three di_erent statistics models. For each one of these models we determined - through several methods of eliminating nuisance parameters - the likelihood function and the pro_le, conditional, uniform integrated, Je_reys integrated and generalized

9. Estimativa da prevalência da Hepatite C, no município de São Paulo, 2003 a 2008, usando o método de captura-recaptura / Estimated prevalence of hepatitis C in the city of São Paulo, 2003 a 2008, using the capture-recapture method
RESUMO Introdução - Estima-se que 2 por cento da população mundial esteja infectada pelo Vírus da Hepatite C e assim, a hepatite C é considerada importante problema de saúde pública por sua magnitude e gravidade. O uso de bancos de dados, originados pelos serviços de saúde, pode ser uma alternativa aos tradicionais inquéritos epidemiológicos de b

10. Dinâmica populacional e efeitos de variáveis ambientais sobre a fauna de pequenos mamíferos em um fragmento de floresta com araucária no sul do Brasil
Natural populations of small rodents fluctuate continually over time and the population dynamics of any living organism are shaped by both intrinsic and extrinsic factors. Small mammals populations can show a continuum dynamic activity, ranging from stability to regular cycles of variable amplitude. The species dynamics is also known to be influenced by the

11. Dispersal and survival of Nyssomyia intermedia and Nyssomyia neivai (Diptera: Psychodidae: Phlebotominae) in a cutaneous leishmaniasis endemic area of the speleological province of the Ribeira Valley, state of São Paulo, Brazil
The dispersal and survival of the phlebotomines Nyssomyia intermedia and Nyssomyia neivai (both implicated as vectors of the cutaneous leishmaniasis agent) in an endemic area was investigated using a capture-mark-release technique in five experiments from August-December 2003 in municipality of Iporanga, state of São Paulo, Brazil. A total of 1,749 males an

12. Small mammals communities in the forest fragments connected by vegetation corridors in the south of Minas Gerais / Comunidades de pequenos mamÃferos em fragmentos florestais conectados por corredores de vegetaÃÃo no sul de Minas Gerais
The forest fragmentation is one of the main threats for the biodiversity. For the fauna, the consequences associated to the forest fragmentation are the original habitat loss, reduction of the fragment size and isolation, which create a number of negative effects over the wild populations, affecting the species richness, the abundance and the animal species
