persistent organic pollutants in juvenile magellanic penguins (spheniscus magellanicus) in south america.magellanic penguins, spheniscus magellanicus, are the most abundant penguins living in temperate regions of south america and are good indicators of environmental pollution in the region. persistent organic pollutants (pops) were detected in the liver of magellanic penguins found debilitated or dead on the beaches of brazil (states of rio de janeiro, sao paulo, santa catarina and rio grande do sul) between 2008 and 2012 as well as in uruguay and chile in 2011. polychlorinated biphenyls (pcbs) we ...201626881336
levels of cadmium, mercury, and lead in magellanic penguins (spheniscus magellanicus) stranded on the brazilian coast.cadmium (cd), mercury (hg), and lead (pb) were determined in samples of liver and breast muscles of first-year magellanic penguins (spheniscus magellanicus), from two different areas on the brazilian coast, 35 on the rio de janeiro coast and 12 on the rio grande do sul coast. in both areas, cd concentrations in muscle samples were <0.025 microg/g. however, the cd and hg concentrations found in liver and hg concentrations found in muscle showed a significant difference between the two regions. th ...201019582498
molecular sexing of unusually large numbers of spheniscus magellanicus (spheniscidae) washed ashore along the brazilian coast in 2008.there have been few studies on magellanic penguins (spheniscus magellanicus). in 2008, these penguins washed ashore along the brazilian coast in unusually high numbers, some reaching as far as northeast brazil. as magellanic penguins show little sexual dimorphism, sex determination by morphological features is not accurate. here, we tested a molecular procedure for sexing specimens of s. magellanicus washed ashore along the coasts of sergipe, rio de janeiro and rio grande do sul in 2008, compari ...201122180075
