(Pontifícia Universidade Católica do Rio Grande do SulPorto Alegre, 2008)
Apesar da sua grande importância, informações sobre a biologia e distribuição dos misídeos são escassas no Brasil. 0 presente estudo foi realizado no estuário da laguna dos Patos e região costeira adjacente, utilizando ...
Sea surface height trend and variability at seasonal and interannual time scales in the Southeastern South American continental shelf between 271S and 401S
(Elsevier, 2014-12)
Recent improvements in satellite altimetry data correction terms are encouraging studies of the remote sensed Sea Level Anomalies (SLA) progressively closer to the coast and over shallow continental shelves. In this paper ...
Use of lapillus otolith microchemistry as an indicator of the habitat of Genidens barbus from different estuarine environments in the southwestern Atlantic Ocean
(Springer, 2015-06)
The marine catfish Genidens barbus is an anadromous species from South America. The aim of the present study was to evaluate the use of lapillus otolith microchemistry (Sr:Ca; Ba:Ca and Mg:Ca ratios) as an indicator of ...
