Our results demonstrated that total abundance was not negatively affected by Hg contamination, since the most contaminated areas presented the highest values, being the copepod Acartia ton...

Assessment of spatial environmental quality status in Ria de Aveiro (Portugal)
Lopes, Cláudia Batista; Pereira, Maria Eduarda; Vale, Carlos; Lillebø, Ana Isabel; Pardal, Miguel Ângelo; Duarte, Armando CostaThe productivity of Ria de Aveiro is sustained by the large quantities of dissolved inorganic nutrients, mainly from freshwater inputs (e.g. agricultural drainage) and organic-rich anthropogenic point sources (e.g. urban sewage). The concentration of silicate and nitrate showed a similar seasonal variation and conservative behaviour, since 63 to 96% of the total variance of the concentration of silicate and 88 ...
