Abstract
In regions of high environmental heterogeneity, it is important to observe if different landscape units are used differently by human populations, which can have consequences for the conservation of these units. Thus, the present study seeks to answer the following questions: (1) are different native vegetation units used for different purposes by the local population? (2) is there a difference between the conservation status of native vegetation units according to the local perception? The study was implemented in the rural community of Morrão de Cima, in the municipality of São Desidério (Northeast Brazil). Data were collected through semi-structured interviews and participatory workshops. The main native vegetation units recognized by the interviewees were Brejo, Mata Seca, Serra and Chapada. The community uses the different units of native vegetation for different purposes. The extraction of medicinal resources was important in the Chapada, while the exploitation of food resources was important in the Brejo, and the collection of wood resources was more substantial in Mata Seca and in Serra. We also found differences in the perceived conservation status of the native vegetation units. Our findings indicate the need of caution when proposing conservation strategies in heterogeneous environments, since each landscape unit may be undergoing specific processes, requiring different strategies.

Abstract
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.

Abstract
BACKGROUND We propose a new quantitative measure that enables the researcher to make decisions and test hypotheses about the distribution of knowledge in a community and estimate the richness and sharing of information among informants. In our study, this measure has two levels of analysis: intracultural and intrafamily. METHODS Using data collected in northeastern Brazil, we evaluated how these new estimators of richness and sharing behave for different categories of use. RESULTS We observed trends in the distribution of the characteristics of informants. We were also able to evaluate how outliers interfere with these analyses and how other analyses may be conducted using these indices, such as determining the distance between the knowledge of a community and that of experts, as well as exhibiting the importance of these individuals' communal information of biological resources. One of the primary applications of these indices is to supply the researcher with an objective tool to evaluate the scope and behavior of the collected data.
