Ethnobiology, Ethnobotany, Gender, Morphological Structure, Environmental Perception
This thesis is divided into four chapters. The first is a general introduction that portrays a review of the importance of Local Ecological Knowledge (CEL) for ecological studies in a rapidly changing world, reports the history of ecological subsidies in ethnobotanical hypotheses and shows the importance of Brazilian researchers and universities for research world ethnobiological research. The second and third chapters are subsidized by 144 interviews with family farmers in the Rural Territory Agreste-Litoral Sul do Rio Grande Norte who provided 3331 citations for 16 group of uses (11 medicinal, four wood and one phenological-hydrological) associated with plant species . In the second chapter, we appropriated medicinal information to discuss how the relations of gender issues and the morphological structures of the plants used help us to understand the path of invasion of exotic species and we point out the conservation route in the traditional medical system. In the third chapter, based on the frequency of citing the uses of the species and a qualitative discussion, we show which are the main trees for reproducing the way of life of family farmers in the Agreste-Litoral Sul Territory. We conclude the thesis by conducting a consensus analysis of the perception of the plurality of perspectives of ecosystem services and the diversity of ethnobotanical uses with agricultural and environmental officials Rural Territory Agreste-Litoral Sul emphasizing a change in the consideration of CEL and social issues for the success of conservation in this rural territory.
