Introduction
Ecologist, interested in community and spacial ecology, mammal ecology, and diversity patterns.
Currently, I am working on a project evaluating the impact of fragmentation caused by oil and gas pipelines on small mammals. I evaluate the impacts on populations and community parameters. At the same time, I have students working on the natural history of those small mammals species (reproduction and behaviour ) in the same areas.

A cigarra-bambu Haplospiza unicolor é uma ave endêmica da Mata Atlântica, que usualmente acompanha a frutificação de bambus do gênero Chusquea. Essa espécie tem registros no Brasil para os estados de Minas Gerais, Espírito Santo, Rio de Janeiro, São Paulo, Paraná, Santa Ca...
Rhagomys rufescens (Thomas, 1886) is an enigmatic arboreal sigmodontine rodent classified at the suprageneric level as "incertae sedis" (Reig 1980; 1984; McKenna and Bell 1997; Smith and Patton 1999; Musser and Carleton 2005). This species was considered a "plesiomorphic Neotropical muroid", according to Voss (1993) and Steppan (1995). Although the...
Mustelidae is the largest and most diverse family within the order Carnivora, encompasses 65 species and 22 genera, and is widely distributed around the world. Mustelids exhibit a multiplicity of coloration patterns, ranging from darker tones, such as black and brown, to lighter tones, such as pale yellow and white. Anomalous colorations in wild mu...
Nests are structures employed by animals for resting, reproduction, and offspring care. The materials involved in the construction of nests vary depending on many aspects (species, environment, availability of resources, among others). Also, there are species that use natural cavities or artificial materials to construct their nests. In this note,...

This study describes Marmosops incanus and Didelphis aurita using their tails to carry plant material, probably for nesting. This is the first record of this behavior for M. incanus and for the tribe Thylamyini. Such description shows that this behavior is widespread amongst didelphid marsupials, indicating that this is a possibly ancestral behavio...
Understanding the predatory behavior of a species is critical to its ecological role. Little is known about the predatory behavior of the marsupial Didelphis aurita . Here, we present two cases to shed light on its opportunistic nature: an opossum struggling to locate and attack an immobile juvenile bird, indicating olfactory detection and visual c...
Este livro é uma síntese dos 20 anos de pesquisas do Sítio PELD Restingas e lagoas costeiras do Norte Fluminense. Ele representa um passo importantíssimo no conhecimento do funcionamento dos ecossistemas costeiros brasileiros. Diferentemente do Parque Nacional da Restinga de Jurubatiba, que preserva as formações vegetacionais e lagoas na planície a...
A dimensão temporal de processos ecológicos e evolutivos geralmente não é a mesma de teses, editais de fomento a pesquisas, ou de vidas humanas. Com o intuito de monitorar e compreender mudanças ambientais em longas escalas temporals ao redor do planeta, há três decadas foi criada a Rede Internacional de Pesquisas Ecológicas de Longa-Duração (ILTER...
Linear infrastructures like roads, pipelines, and electrical networks are among the main causes of habitat fragmentation and diversity loss in animal species. We evaluated the effects of 20-30 m wide deforested corridors above underground oil pipelines on the movements of the long-furred woolly mouse opossum Marmosa paraguayana, an arboreal marsupi...
Os pequenos mamíferos não voadores constituem um grupo diverso de espécies de marsupiais e pequenos roedores que exercem importantes funções ecológicas nos ecossistemas neotropicais. O Parque Nacional da Restinga de Jurubatiba (PNRJ) tem sido alvo de numerosos estudos com pequenos mamíferos, abordando desde a ecologia populacional das espécies até...
As mudanças climáticas globais têm sido frequentemente apontadas como principal impacto futuro nas populações animais, afetando suas taxas de crescimento e elevando seu risco de extinção. Contudo, ainda não se sabe como as populações de pequenos vertebrados tetrápodes (anfíbios, répteis e pequenos mamíferos) de ecossistemas tropicais sujeitos ao es...
The Caatinga is an exclusively Brazilian biome, and is the largest and most biodiverse Seasonal Tropical Dry Forest in the world. Despite that, the mammalian fauna, especially small mammals, is the least studied of all Brazilian biomes. In order to fill gaps and provide detailed information on small mammals (Didelphimorphia, Rodentia) in the Caatin...
Mercury (Hg) is a widespread and toxic contaminant with potential for long-range atmospheric transport. Previous work has shown that temperate and subtropical montane ecosystems have great potential for deposition of this element. However, little information exists regarding Hg dynamics in tropical mountains. In present study, we evaluated the infl...
Despite the well-established anatomy nomenclature for the marsupial skeleton, there are no names for the epipubic bone structures. Epipubic bones are paired bones articulating with the pubis and projecting cranially in the ventral body wall, present on the pelvic girdle of cynodonts, monotremes and marsupials. These bones were commonly thought to b...
Small rodents rely on resource gathering during the breeding season to support their reproductive output and offspring survival. Since croplands may provide complementary food sources, we evaluated the influence of the presence of cornfield on the forest edge in Oligoryzomys nigripes (Olfers 1818) abundance and breeding. We found that abundance, pr...

Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In...
Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropica...
This study describes the hunting and predatory behavior of the lesser grison on an adult black-and-white tegu as recorded by camera traps in an Atlantic forest remnant in the União Biological Reserve (Rio das Ostras, RJ, Brazil). This is the rst record of a mustelid preying on this large lizard species and the rst direct record of a hunting event o...
The role of environmental factors and landscape heterogeneity on species distribution on different spatial scales is one of the most important questions in community ecology. Variations in the environmental gradient characteristics, host attributes and spatial scales may influence the parasites distribution. The helminth metacommunity of 12 small m...
Resumo Deforestation, fragmentation and urbanization of natural areas in Colombian Andes have led to the loss and modiication of habitat for native mammals, especially scansorial and arboreal ones. Understanding the impacts of these anthropogenic interventions on Andean mammals' species, may allow nding alternatives to mitigate their negative effec...
Long-term ecological studies have been developed in a Quaternary coastal plain in Southeastern Brazil (RLaC site), comprising the largest protected restinga remnant (144km2) in South America. Restingas are sandy areas spread along the Brazilian coast comprising a mosaic of open woodland vegetation, spots covered by dry or wet forests, swales and wa...
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...
Marsupials have short gestation periods, with altricial neonates completing their development attached to a teat, a condition that induces remarkable structural changes in the inguinal region of reproductive females. In this study, we analyzed the morphological variation in the inguinal region of female museum specimens of Monodelphis domestica in...

Context
The metacommunity concept helps to understand how local and regional processes regulate species distributions in landscapes. Metacommunity structure is often assumed as static, but may be rather dynamic, following temporal changes along environmental gradients.
Objectives
We present an empirical test of the temporal dynamics of metacommuni...
We evaluated the use of both ethnozoological and conventional sampling methods to the inventory medium and large-bodied mammals. Our study was conducted at Serra do Ouro Branco, southern portion of Espinhaço Range, Minas Gerais state, Brazil. Ethnozoological methods comprehended interviews and projective tests carried out with 107 residents of thre...
Here we compile a data set comprising morphological and life history information of 279 mammal species from 39,850 individuals of 388 populations ranging from 5.83 to 29.75 decimal degrees of latitude and 34.82 to 56.73 decimal degrees of lon- gitude in the Atlantic forest of South America. We present trait information from 16,840 individ- uals of...
Measures of traits are the basis of functional biological diversity. Numerous works consider mean species-level measures of traits while ignoring individual variance within species. However, there is a large amount of variation within species and it is increasingly apparent that it is important to consider trait variation not only between species,...
Marsupials have epipubic bones, also present in cinodonts, monotremes and non-placental eutherians, but absent in placental mammals. There is two non-excludent hypothesis about its function: i) Reproductive hypothesis: to support the marsupium; ii) Locomotive hypothesis: Muscle insertion connected with locomotion. To test the first hypothesis, we a...
Metacommunity theory aims to explain how processes that operate in distinct spatial scales interact to determine the
distribution and local occurrence of species. This theory has developed rapidly in recent years, and is regarded as a promising
approach to the study of global ecological changes. In the present study, we review the concepts related...
Abrawayaomys is a genus endemic to the Atlantic Forest with unique craniodental attributes within the radiation of sigmodontine rodents. Recent data hypothesized the existence of 2 species of Abrawayaomys, namely A. ruschii (from the Brazilian states of Espírito Santo, Rio de Janeiro, and São Paulo) and A. chebezi (from the Argentinean province of...

We report three new records of Neusticomys fer-reirai, a rare species of fish-eating rat from the Brazilian Amazon basin, and extend the known geographical distribution of the species. Also, we provide the collection and identification of the specimens using morphological and molecular data, and report the phylogenetic position of the species in re...
Serra do Ouro Branco is located at the south portion of Espinhaço Range, at a transition area between Cerrado and Atlantic Forest biomes, in Minas Gerais state, Brazil. Here, we surveyed small mammals communities from Parque Estadual Serra do Ouro Branco and Monumento Natural Estadual do Itatiaia, two protected areas, and compared them with the div...
Croplands have expanded dramatically during the last century, frequently leading to severe biodiversity losses within occupied areas. In addition to such direct influences, croplands may also have affected biodiversity within adjacent natural habitats, yet such potential indirect effects have rarely been quantified. Here, we test for effects of cor...

I used MaxEnt to generate a model distribution for a species with occurence in Atlantic Forest in Brazil and Missiones in Argentina and it fails to predict the distribution in Missiones even using regularization parameter multiplied by 4. There are 5 occurrences in Missiones and the model predicts the distribution almost only in the Atlantic Forest in the mountainous regions in Brazil. Any ideas?
I have around 50 communities and want to know the best way to estimate the distance decay between them. I want a package in R to do this. Any suggestions?
