Abstract The rapid changes in the climate of Antarctica are likely to pose challenges living communities, which makes monitoring Antarctic fauna an urgent necessity. Benthos is particularly difficult monitor, and sensitive local environmental changes. At same time, long‐term complicated by logistical factors. It therefore develop advanced instruments set up autonomous programmes obtain lacking ...

pollution deriving from trace elements (cd, cu, ni, pb, zn, hg, as and cr) in sediment samples(collected in 2009), belonging to rivers located in catalonia and the basque country (spain), was assessedaccording to sediment quality guidelines. sediment samples were ranked in terms of a pollution index thattakes into account the presence of multiple pollutants such as trace elements. while only ab...

Benthic fauna caught by ring dredge and 2 m beam trawl at the NATURA 2000 Sylt Outer Reef (SAR) Borkum Ground (BRG) sites in North Sea are examined relation to intensity of mobile bottom-trawling fisheries. Samples were taken from 33 stations two areas, collected benthic fauna, consisting infauna, epifauna, demersal fish was determined. A total 123 species found, phyla Chordata, Mollusca, Arthr...

OBJECTIVE To study the impacts of abundance of woodlice, termites, and mites on some functional aspects of soil in order to elucidate the specific role of soil fauna in improving soil fertility in desert. METHODS Fauna-rich sites were selected as experimental sites and adjacent areas were taken as control. Soil samples were collected from both sites. Soil respiration was measured at both site...

Quantifying of sediment reworking processes provides new insights into benthic ecosystem functioning of the Thau lagoon, an important European shellfish farming area. In order to evaluate bioturbation rates of surface sediments, profiles of 7Be (half-life: 53 days) and 234Th (half-life: 24.1 days) were measured in cores collected since December 2001 to December 2006. Several sites were selected...

Port activities such as ship traffic and dredging of port basin's sediment can impact biological communities the benthos, composition which remains unknown. Moreover, knowledge ivorian’s basin benthic fauna is concern to both scientists authorities in development their activities. This study carried out July December 2021, aimed provide first data on San-Pédro’s macroinvertebrates communities. ...

large benthic foraminifera and dasycladalean green algae are the most common and important (micro) fossils in lower cretaceous shallow-water sediments of the tethyan realm. in this paper, we introduced such taxa and their importance in age dating of lower cretaceous strata in the kopet-dagh sedimentary basin. also, according to determinations of index taxa (fauna and flora) in this period, the ...
