Striped dolphins as trace element biomonitoring tools in oceanic waters: accoun...
Monteiro, Sílvia S.; Bozzetti, Márcia; Torres, Jordi; Tavares, Ana S.; Ferreira, Marisa; Pereira, Andreia T.; Sá, Sara; Araújo, HélderIn Europe, monitoring contaminant concentrations and their effects in the marine environment is required under the Marine Strategy Framework Directive (MSFD, 2008/56/EC). The striped dolphin (Stenella coeruleoalba) is the most abundant small cetacean species in Portuguese oceanic waters, representing a potential biomonitoring tool of contaminant levels in offshore waters. Concentrations of nine trace elements w...
The importance of Portuguese Continental Shelf Waters to Balearic Shearwaters r...
Araújo, Hélder; Bastos-Santos, Jorge; Rodrigues, Pedro Correia; Ferreira, Marisa; Pereira, Andreia; Henriques, Ana Catarina; Monteiro, Sílvia S.The Balearic shearwater Puffinus mauretanicus is one of the most threatened seabirds in the world. To evaluate the abundance and distribution of Balearic Shearwaters in Portuguese Continental Shelf Waters, during the post-breeding period when migrating birds are outside the Mediterranean Sea, we conducted 5 aerial surveys between 2010 and 2014 (21 survey days covering 62,716 km2). Following a line transect meth...
Trace elements in loggerhead turtles (Caretta caretta) stranded in mainland Por...
Nicolau, Lídia; Monteiro, Sílvia S.; Pereira, Andreia T.; Marçalo, Ana; Ferreira, Marisa; Torres, Jordi; Vingada, José V.; Eira, CatarinaPollution is among the most significant threats that endanger sea turtles worldwide. Waters off the Portuguese mainland are acknowledged as important feeding grounds for juvenile loggerheads. However, there is no data on trace element concentrations in marine turtles occurring in these waters. We present the first assessment of trace element concentrations in loggerhead turtles (Caretta caretta) occurring off t...
