Caatinga revisited: ecology and conservation of an important seasonal dry forest.

Besides its extreme climate conditions, the Caatinga (a type of tropical seasonal forest) hosts an impressive faunal and floristic biodiversity. In the last 50 years there has been a considerable increase in the number of studies in the area. Here we aimed to present a review of these studies, focusing on four main fields: vertebrate ecology, plant ecology, human ecology, and ethnobiology. Furthermore, we identify directions for future research. We hope that the present paper will help defining actions and strategies for the conservation of the biological diversity of the Caatinga.

Environmental perception and use of fauna from a Private Natural Heritage Reserve (RPPN) in Brazilian semiarid - doi: 10.4025/actascibiolsci.v34i3.8763

This paper analyzes the Environmental Perception about the potential use of wildlife resources by the population surrounding the RPPN Stoessel de Britto. Through open and closed questions, we interviewed 90 residents at Laginhas community (87% of domiciles), which performed 367 citations for 79 species, belonging to 78 genera and 55 families. The interviewees showed the utility of 41 species, for various purposes, the feeding purpose was the most mentioned. The most cited animal (27) was Tolypeutes tricinctus (Linnaeus, 1758), the three-banded armadillo. The knowledge of this community is rich and could be considered and used to define conservation strategies and as subsidies to elaborate the Plan of Management of Conservation Units.
