Resumo

In xeric environments, such as Caatinga Biome, habitat characteristics such as phytophysiognomy type and presence of water bodies can represent higher resource availability. In this context, the present study investigated the effect of phytophysiognomies and presence of water bodies in the abundance and community structure of medium and large mammal species (MLM) in the Serra de Santa Catarina, Paraíba, Brazil. To evaluate these variables we conduct an effort of 373 camera-trap days, between August 2012 and November 2014. We recorded 12 MLM species, distributed in six orders and 11 families. From those, Kerodon rupestris is the only one listed in the Brazilian List of Threatened Fauna. Regarding the habitat, the Mann-Whitney showed a significant higher frequency to the Shrubby habitat and the ANOSIM showed no shifts in the community structure between Arboreal and Shrubby. Concerning the presence of water bodies, both the Mann-Whitney and the ANOSIM showed significant higher frequency to the habitat with water presence. We observed that both phytophysiognomy and water bodies are important variables which affect mainly the abundance of mammalian species from semiarid environments. Nonetheless, whereas the forest remnants get smaller the existence of water bodies becomes a preponderant factor to the MLM species and its community structure.(AU)

Abstract The bat genus Sturnira is widely distributed in the Neotropical region, from northwestern Mexico to northern Argentina, and four species occur in Brazil: Sturnira lilium, Sturnira giannae, Sturnira magna, and Sturnira tildae. The present study is the first to record Sturnira tildae in the state of Maranhão, Brazil, based on morphological and molecular diagnoses. The specimen was identified based on its cranial and morphometric traits. The diagnostic traits include discreetly bilobed inner upper incisors with a broad base, lower first and second molars with lingual cusps separated by shallow grooves, and forearm longer than 45 mm. The molecular sequences of Cytochrome C Oxidase Subunit 1 (COI) and 16S rRNA genes confirmed the morphological identification and thus the occurrence of Sturnira tildae in the Amazon biome of Maranhão. This record represents an eastward extension of the known distribution of the species in the Amazonia, to Cândido Mendes, Maranhão, within an area dominated by dense rainforest and influenced by tides.

Resumo

There were identified 19 species of nonvolant mammals on the Serra da Guia region, municipalities of Poço Redondo - Sergipe and Pedro Alexandre - Bahia. The samplings were conducted between December 2008 and August 2009, in two different areas: Caatinga dry scrub and a Cloud Forest enclave, in which were placed 10 Sherman type traps, within three nights per month. To mid and large mammals species, existing transects of 1,000 m were traveled, searching for tracks, sightings, feces or vocalizations. Among sampled species, only Leopardus tigrinus is in the IUCN Red List, classified as Vulnerable (VU). Regarding the differences between the study sites, some species were sampled only in exclusive areas, as: Monodelphis domestica and Thrichomys laurentius to Caatinga dry scrub; and Marmosops incanus, Trinomys albispinus and Oecomys catherinae to Cloud Forest. Continued studies may provide more information about the mammal diversity and the role of Cloud Forest in the maintenance of such diversity, to the Caatinga Biome.


Foram identificadas 19 espécies de mamíferos não voadores na região da Serra da Guia, nos municípios de Poço Redondo, Sergipe e Pedro Alexandre, Bahia. As amostragens foram realizadas nos meses de dezembro 2008 a agosto 2009 em duas áreas: caatinga arbustiva e brejo de altitude, nas quais foram colocadas 10 armadilhas tipo Sherman, com três noites de amostragem por mês, para a captura de mamíferos de pequeno porte. No caso dos mamíferos de médio e grande porte, foram realizados transectos de 1.000 m em trilhas pré-existentes, na busca de rastros, visualizações, fezes e vocalizações. Dentre as espécies de amostradas, apenas Leopardus tigrinus consta na Lista Vermelha da IUCN, classificada como Vulnerável (VU). Em relação à distinção entre os ambientes, algumas espécies foram capturadas exclusivamente em determinadas áreas, como: Monodelphis domestica e Thrichomys laurentius para Caatinga arbustiva; e Marmosops incanus, Trinomys albispinus e Oecomys catherinae, para brejo de altitude. Com estudos contínuos podem ser fornecidas maiores informações sobre a diversidade de mamíferos não voadores e o papel dos brejos de altitude na manutenção da mesma, no bioma Caatinga.
