Benthic primary production and nutrient cycling in sediments with benthic microalgae and transient accumulation of macroalgae
Annual rates of sediment denitrification and sediment–water fluxes of oxygen and nutrients were quantified at two shallow locations, Virksund and Ulbjerg, in the Limfjorden, Denmark. The sediment was sandy and colonized mainly by bivalves with a wet weight of 2,508 g m22 at Virksund and 572 g m22 at Ulbjerg. A benthic microalgal community was present throughout the year, and for 1–2 months in t...

متن کاملNitrogen cycling in coastal marine ecosystems.
It is generally considered that nitrogen availability is one of the major factors regulating primary production in temperate coastal marine environments. Coastal regions often receive large anthropogenic inputs of nitrogen that cause eutrophication. The impact of these nitrogen additions has a profound effect in estuaries and coastal lagoons where water exchange is limited. Such increased nutri...

testing plays a vital role in any language teaching program. it allows teachers and stakeholders, including program administrators, parents, admissions officers and prospective employers to be assured that the learners are progressing according to an accepted standard (douglas, 2010). the problems currently facing language testers have both practical and theoretical implications but the first i...
