Impact of mercury contamination on the population dynamics of Peringia ulvae (G...
Cardoso, P G; Sousa, E; Matos, P; Henriques, B; Pereira, E; Duarte, A C; Pardal, M AThe effects of mercury contamination on the population structure and dynamics of the gastropod Peringia ulvae (also known as Hydrobia ulvae) and its impact on the trophic web were assessed along a mercury gradient in Ria de Aveiro (Portugal). The gastropod was revealed to be a tolerant species to the contaminant, since the highest densities, biomasses and growth productivity values were recorded at the intermed...
Mercury intracellular partitioning and chelation in a salt marsh plant, Halimio...
Válega, M; Lima, A I G; Figueira, E M A P; Pereira, E; Pardal, M A; Duarte, A CIn the presence of metal stress, plants can resort to a series of tolerance mechanisms. Therefore field studies should be undertaken in order to evaluate the real role of these mechanisms in stress coping. The aim of this paper was to clarify the biochemical processes behind mercury tolerance in Halimione portulacoides (L.) Aellen (Caryophyllales: Chenopodiaceae) collected in a mercury contaminated salt marsh. ...
The effect of zostera noltii, spartina maritima and scirpus maritimus on sedime...
Lillebø, A I; Flindt, M R; Pardal, M A; Marques, J CThe objective of the present work was to study the effect of plants common in temperate latitudes (Zostera noltii, Spartina maritima and Scirpus maritimus) on sediment nutrient profiles, and to compare it to sandand mud-flats without vegetation. The study focused on the organic matter contents, the concentration of dissolved inorganic nutrients (PO4–P, NH3–N, NO3–N), an on the estimation of the total amount of ...
