Cetaceans are sentinels of marine ecosystem health and are increasingly exposed to protozoal pathogens. This study investigated the occurrence and molecular identity of Sarcocystidae protozoa in 159 stranded cetaceans representing 21 species along the Brazilian coast. Molecular analysis based on PCR amplification and sequencing of the sarcocystid internal transcribed spacer 1 (ITS1) region revealed infections in 14 individuals...

Phytoplankton and zooplankton organisms are important constituents of the Antarctic marine food-web and play important roles in carbon export. This study analysed the composition and vertical distribution of zooplankton in association with phytoplankton community composition over a 20 h in February 2017 at a fixed station in the central basin of the Bransfield Strait. The water column was stratified, resulting in the dominance...
