In this study we present data on the richness of sharks and rays from the southern coast of São Paulo, southeastern Brazil, in a coastal area considered as an essential habitat for many species of elasmobranchs. Based on ... -
Do water dynamics and land use in riparian areas change the spatial pattern of physical–mechanical properties of a Cambisol?
da Silva, Reginaldo Barboza; ; ; ; ; de Melo Silva, Francisca Alcivânia ; (Precision Agriculture, 2022) [Artigo]
Changes in land use in riverside ecosystems added to the flood and ebb regimes of rivers modify the spatial variability of the physical–mechanical attributes of soil, making it more susceptible to degradation processes, ... -
Fish otolith microchemistry as a biomarker of the world's largest mining disaster
