It is repeatedly stressed the need to characterize the extant biodiversity in tropical ecosystems. However, inventory studies are still progressing slowly in dry ecosystems, leading to the underestimation of their true biodiversity and hindering conservation efforts. In this study, we present primary and secondary data, along with an updated list o...
Competition can generate different ecomorphological patterns resulting in trade-offs, considering that certain resources are better used than others. We investigated how three species of Boana share resources in Serra de Itabaiana National Park and how morphology and environment cause trade-offs in interactions. We hypothesized that the large body...
Phylogenetically close species are expected to exhibit similar characteristics related to their ecology. However, differences in some niche dimensions are necessary for coexistence. In this study, we evaluated the trophic ecology of the treefrogs Boana albomarginata and B. pombali, which live in sympatry in the Serra de Itabaiana National Park, Nor...
We studied a population of Tropidurus hygomi in an area of geographic disjunction located in Brazil's Northeast, investigating how individuals use the microhabitats, what is their daily activity in different seasons, how does growth and mass gain occur and what is the sex ratio, besides analyzing the population dynamics and the recruitment period....
Microhabitat choice by tadpoles is related to several physical or biological characteristics, and variations in these factors have a direct influence on their distribution and abundance at different scales (e.g. time, space). Our work sought to investigate how Pithecopus nordestinus tadpoles use water bodies at a Caatinga site and quantify how biot...
We investigated the roles of ecological and historical factors on the phylogenetic structure and spatial and trophic niches of anurans in Caatinga and Atlantic Forest in the Brazilian Northeast Region. We sampled specimens and ecological data using both active search and pitfall traps to sample sites for 15 days during dry and wet seasons. Assembla...
Alguns indivíduos da Ordem Anura, Classe
Amphibia, tem um ciclo e vida complexa, uma fase
larval aquática e herbívora, e uma fase adulta
terrestre e carnívora. Os girinos são filtradores, com
uma dieta com ampla variedade de algas, mas se
alimentam de outros itens presentes no ambiente. O
presente trabalho é o primeiro a tratar de dieta de
girinos...
p>Lagartos frequentemente são parasitados por espécies de Acari (ácaros e carrapatos). No presente estudo relatamos a ocorrência de Amblyomma sp. (carrapato) parasitando um indivíduo juvenil de Tropidurus hispidus (Spix, 1825). A observação foi realizada no Parque Nacional Serra de Itabaiana (PNSI) no estado de Sergipe, nordeste do Brasil.

Understanding of how environmental dynamics affect the ecological niche of populations is one of the great aims ecological research. Amphibian populations are taking part in a series of complex interactions with the environment. The aim of this study was to investigate potential differences in the use of spatial, temporal and trophic resources, and...
The family Anguidae contains three subfamilies: Gerrhonotinae, Anguinae, and Diploglossinae. In Brazil, there are four described anguid species, all from the subfamily Diploglossinae. Herein, we present the first records of Diploglossus lessonae Peracca, 1890 from the state of Sergipe and new records for the states of Paraíba and Ceará. The records...
A dieta de qualquer espécie está relacionada com aspectos ecológicos de suas populações, bem como a história evolutiva do táxon, sofrendo influências de diversos fatores, intrínsecos e extrínsecos. Em Sergipe, foram realizados poucos estudos com ecologia de lagartos na Mata Atlântica, sendo assim, o presente trabalho teve por objetivos: descrever a...
All the species of Physalaemus Fitzinger, 1826 karyotyped up until now have been classified as 2n = 22. The species of the Physalaemus cuvieri group analyzed by C-banding present a block of heterochromatin in the interstitial region of the short arm of pair 5. Physalaemus cicada Bokermann, 1966 has been considered to be a member of the Physalaemus...
Lagartos usam regiões específicas do ambiente que propiciem melhores recursos para a espécie. Foi investigada a partilha de recursos espaciais entre lagartos de um fragmento de Mata Atlântica do IFS, São Cristóvão, SE. Os dados foram tomados entre outubro/2015 e maio/2016 por busca ativa e armadilhas (pit fall e de cola). Foram registrados 208 laga...
Thermal variability and composition of available micro-habitats influence directly on the
activity patterns of lizards, generating specific temperature regulation and resource allocation.
Aspects of natural history of Tropidurus semitaeniatus, such as daily and seasonal
activity and habitat use, were studied in the Serra de Itabaiana National Park,...
This study examines how two species of diurnal lizards (Tropidurus semitaeniatus and T. hispidus, Tropiduridae) use spatial, trophic and temporal resources in the Conservation Unit of Monumento Natural Grota do Angico, Poço Redondo, Sergipe (Brazil). Both species were mostly active during sunny days, with a reduction in activity during the hottest...
Despite the increase in herpetofaunal inventories in the Caatinga biome, information for many areas is still lacking and new surveys are required. We conducted a 30-day inventory of the herpetofauna of the Catimbau National Park, Pernambuco State, Brazil. Thirty-seven pitfall trap arrays composed of 4 buckets each, along with glue traps and active...
The forms of spatial and temporal resources use of two sympatric species of Ameivula were studied in an Atlantic Forest-Caatinga ecotone located in Parque Nacional Serra de Itabaiana, Sergipe, Brazil. The study was conducted between February 2008 and January 2009. The method used was an active search for a limited time, from 06:00 am to 06:00 pm. T...
Seasonality, pattern of activity, habitat composition and temperature are factors that exert strong influence on the lives of lizards. Aspects of the natural history (daily and seasonal activity and habitat and microhabitat use) of Tropidurus hispidus were studied in the Serra de Itabaiana National Park, northeastern Brazil. Lizards were caught by...

Frogs in the family Leptodactylidae have diploid chromosome numbers ranging from 2n = 18 to 2n = 26, although there is a predominance of 2n = 22 karyotypes. In the present study, 52 specimens of Leptodactylus fuscus and Leptodactylus latrans were obtained from three municipalities (Carira, Pogo Redondo, and Tobias Barreto) of the Brazilian state of...
Corbicula fluminea is native mollusk from China. In Brazil, this species was first recorded in Rio Grande do Sul state in the late 70’s, being also recorded in the Amazonia basin between 1997 and 1998. The present note reports the occurrence of C. fluminea for the first time in the Caatinga biome and extends considerably the geographical distributi...
We provide a list of amphibian and squamate species collected in the Raso da Catarina Ecological Station, Bahia state, Brazil, during two distinct periods. An initial visual inventory of amphibians was conducted monthly from March 2010 to February 2011, using transects in a forest and temporary ponds. The second inventory was conducted over a 30- d...
The Brazilian Atlantic Rainforest has high diversity levels of amphibians and reptiles, but there is a lack of richness survey at several areas, while a high level of deforestation is already known. The biome is highly endangered in northeastern Brazil, and few protected areas have been the main mechanism for providing the habitat conservation. We...
