O município de São José de Princesa, localizado no Estado da Paraíba, tem enfrentado problemas relacionados às instalações insuficientes para o Sistema de Abastecimento de Água (SAA) que contempla a população da cidade. Deste modo, este trabalho tem como objetivo analisar a qualidade da água que é fornecida de acordo com as variáveis físicas e químicas, visando uma melhoria da qualidade de vida para os munícipes. Foram realizadas visitas in loco e entrevistas com parte da população. Este estudo desempenha um trabalho com finalidade de avaliar os riscos que a população possa estar exposta com efeitos adversos que um SAA mal planejado possa oferecer.
RESUMOO levantamento florístico é uma ferramenta indispensável para o conhecimento de um ecossistema, pois visa conhecer as espécies que ocorrem em uma determinada área geográfica. O objetivo do Palavras-chave: levantamento florístico, ecossistemas, censo.
The suppression of native vegetation due to inadequate practices has contributed to the non-survival of many plant species, resulting in the loss of the genetic heritage of the Caatinga flora. However, their growth and establishment can be improved by the presence of arbuscular mycorrhizal fungi (AMF), a symbiotic association formed by plant roots and soil fungi that helps seedlings to increase nutrition and tolerance to water deficit, a common situation in stressful environments such as the Caatinga. This review aimed to discuss the importance of mycorrhizal fungi in the development and conservation of native species of the Caatinga that live under water stress, highlighting the effects caused by arbuscular mycorrhiza, its importance for conservation and mechanisms of plant adaptation to stress. The research sought to gather data from articles and journals with the help of key words indexed in Science Direct, Scientific Eletronic Library Online (SciELO), on the Google Academic platform and in the Catalog of Theses and Dissertations of the Coordination for the Improvement of Higher-Level Person (Capes). The results indicate that the inoculation of arbuscular mycorrhizal fungi through root growth can increase the absorption of water and nutrients, assisting in the development of local plants of the Caatinga that live under stress, contributing to the structure of the plant community and the functioning of the natural ecosystem. As research on this subject is still scarce, it is necessary to disseminate research on this subject in order to obtain a wider range of information.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
