(Universidade Federal de São Carlos, 2018-02-05)
Environmental issues have been increasingly discussed today, and many ways have been sought to measure ecosystems’ biodiversity. In addition to the taxonomic diversity, one of the possible alternatives used to obtain ...
Efeitos da implantação da UHE Colíder na dinâmica fluvial e na qualidade da água do curso médio do Rio Teles Pires (Mato Grosso)
(Universidade Federal de São Carlos, 2019-12-10)
This study aimed to discuss the process of land occupation and land use, as well as evaluating river dynamics and water quality in the middle course of the Teles Pires river. This study is predicated on the hypothesis that ...
