Distribution and Potential Availability of As, Metals and P in Sediments from a...
Reis, Anabela R.; Roboredo, Marta; Pinto, João P. R. M.; Vieira, Bernardete; Varandas, Simone G. P.; Fernandes, Luis F. S.; Pacheco, Fernando A. L.A geochemical investigation was carried out on the bottom sediments of a riverine reservoir, located in a mountainous rural region (NE Portugal), with the aim of evaluating the contents of As, metals and P and their potential availability. The elements contents were detected in the following ranges (µg g-1): As (18-64); Cr (32-128); Cu (39-93); Ni (18-80); Pb (49-160); Zn (207-334); P (1705-2681). The reducible...
The Impact of Land Use Transformations on Zooplankton Communities in a Small Mo...
Sługocki, Łukasz; Czerniawski, Robert; Kowalska-Góralska, Monika; Senze, Magdalena; Reis, Anabela R.; Carrola, João; Teixeira, Carlos A.Transformation of the river catchment and the river bed cause significant changes in the functioning of river ecosystems. The main effects of anthropogenic transformations are hydrological changes, such as lower current velocity or an increase of nutrient content, and higher temperature. Zooplankton reacts rapidly to the new environmental conditions in rivers, increasing its richness and abundance. We tried to ...
