“…Offshore nematode communities appear to be more susceptible to metals than near-shore communities (Austen and McEvoy 1997). High levels of heavy metals potentially generate test deformities in benthic foraminifera and modify community structure (e.g., Alve 1995;Ruiz et al 2004;Armynot du Châtelet et al 2004;Ferraro et al 2006;Le Cadre and Debenay 2006). In an experimental study, Alve and Olsgard (1999) found that foraminifera were able to colonise sediments that were severely contaminated with copper.…”

Our planet is changing, and one of the most pressing challenges facing the scientific community revolves around understanding how ecological communities respond to global changes. From coastal to deep-sea ecosystems, ecologists are exploring new areas of research to find model organisms that help predict the future of life on our planet. Among the different categories of organisms, meiofauna offer several advantages for the study of marine benthic ecosystems. This paper reviews the advances in the study of meiofauna with regard to climate change and anthropogenic impacts. Four taxonomic groups are valuable for predicting global changes: foraminifers (especially calcareous forms), nematodes, copepods and ostracods. Environmental variables are fundamental in the interpretation of meiofaunal patterns and multistressor experiments are more informative than single stressor ones, revealing complex ecological and biological interactions. Global change has a general negative effect on meiofauna, with important consequences on benthic food webs. However, some meiofaunal species can be favoured by the extreme conditions induced by global change, as they can exhibit remarkable physiological adaptations. This review highlights the need to incorporate studies on taxonomy,

“…But also lead us to think that species such as H. germanica and A. tepida should tolerate higher level of stress caused by these pollutants. A. tepida has been considered one of the most tolerant species to high heavy metal concentration and is used as a bio-indicator of pollution of anthropized marine sediments (Ferraro et al, 2006). H. germanica was also considered a bio-indicator of pollution by metals (Frontalini et al, 2011;Romano et al, 2008) and of pollution by metals and hydrocarbons (Armynot du Châtelet et al, 2004).…”

This work evaluates the quality of the sediment in Ria de Aveiro, a coastal lagoon located at N of Portugal that is under strong anthropic influence, and the effects of the contamination on benthic foraminifera. The initial approach for measuring pollution was done through the load pollution index (LPI), based on As, Cd, Cr, Cu, Ni, Pb and Zn concentrations, and determined by total digestion of the sediments (TDS). This information was complemented by conducting a metal fractionation technique (sequential chemical extraction -SCE) in some of the most contaminated samples in order to define the relevance of different metal bearingphases (exchangeable cations adsorbed by clay and co-precipitated with carbonates, absorbed by organic matter and retained in the mineralogical phase) and to evaluate the toxic heavy metal availability. Multivariable statistical analyses were carried out taking into consideration the geochemical results, as well as the biotic (percentage of species/groups of species; foraminifer abundance and diversity) and abiotic variables, such as sediment content in mud, total organic carbon (TOC) and Eh.SCE results show that most of the element concentration in the sediments is retained in the resistant mineralogical phase. However, the higher bioavailability of some toxic elements, such as As, Cd, Cu, Hg, Ni, Pb and Zn, found in Laranjo Bay, Aveiro City, Aveiro Harbours and Espinheiro Channel, have a generic negative impact on benthic foraminifera of the Aveiro lagoon. Differential sensitivity of benthic foraminifera to high concentrations of heavy metals may exist. Quinqueloculina seminulum, for instance, seems to be more tolerant to higher bioavailable concentrations of Pb and Cu than Ammonia tepida or Haynesina germanica. Both

“…Esta espécie euribionte é característica de ambientes costeiros rasos, adaptada a grandes variações ambientais (Bradshaw, 1961;Murray, 1991;Kitazato, 1994). Ammonia tepida é reportada por muitos autores como dominante em regiões sob estresse ambiental, onde espécies estenobióticas tendem a diminuir suas densidades ou até mesmo desaparecer (Alve, 1995;Armynot du Châtelet, Debenay, Soulard, 2004;Ferraro et al, 2006;Lê Cadre e Debenay, 2006). Segundo Debenay e Fernandez (2009), Ammonia tepida é considerada espécie com potencial para biomonitoramentos, principalmente quando se refere a impactos ambientais ocasionados por atividades antrópicas.…”
