Organization of fish assemblages in blackwater Atlantic Forest streams
Esteves,Katharina Eichbaum; Silva,Marcelo Horikoshi Candido; Nanini-Costa,Maressa Helena; Petesse,Maria LetiziaABSTRACT This study aimed to determine whether fish species occupy different mesohabitats, as defined by specific criteria of substrate types in Atlantic Forest blackwater streams. We sampled fourteen coastal blackwater rivers along the coast of São Paulo State, Brazil, during the low-flow season (June-September/2016). For each stream, we selected three mesohabitat types (sand, leaf-litter and trunks) in a 100 ...
Study approach and step by step development of a fish-based multimetric index f...
Petesse,Maria LetiziaAbstract Aim The present paper approached some issues related to the construction and adaptation of the Reservoir Fish Assemblage Index (RFAI). Method the case study presents the step by step construction of the multimetric index adopted for the Tietê cascade reservoir system, and it is discussed the comparison between discrete and continuous scoring criteria. Results The main questions related to the adaptatio...
Metal trace elements in mussels in Urubuqueçaba Island, Santos Bay, Brazil
Campolim,Marcos Bührer; Henriques,Marcelo Barbosa; Petesse,Maria Letizia; Rezende,Karina Fernandes Oliveira; Barbieri,EdisonAbstract: The objective of this work was to verify the existence of bioaccumulation in mussels of the species Perna perna, by determining the concentration of metal trace elements, in Urubuqueçaba Island, Santos Bay, Santos, SP, Brazil. Mussels were collected in natural banks and rocky shores, and sampling took place from April 2010 to June 2011. The concentration of the trace metal elements - aluminum, cadmium...
