Effect of settled diatom‐aggregates on benthic nitrogen cycling
The marine sediment hosts a mosaic of microhabitats. Recently it has been demonstrated that the settlement of phycodetrital aggregates can induce local changes in the benthic O2 distribution due to confined enrichment of organic material and alteration of the diffusional transport. Here, we show how this microscale O2 shift substantially affects benthic nitrogen cycling. In sediment incubations...
متن کاملMicrobial degradation of organic carbon and nitrogen on diatom aggregates
The major pathways of transformation of particulate organic matter by heterotrophic bacteria are respiration and production of new biomass. Until today only a limited number of studies have measured simultaneously respiration and production by aggregate-associated bacteria. To study their role in the carbon cycle of aquatic systems we have formed model particles from diatoms (Skeletonema costat...
متن کاملeffect of oral presentation on development of l2 learners grammar
this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...
15 صفحه اولCarbon and nitrogen cycling on intertidal mudflats of a temperate Australian estuary. I. Benthic metabolism
The light and dark inundated fluxes of O2 and total CO2 (TCO2), as well as the concentrations of chlorophyll a and phaeopigments, were measured (ex situ) on the upper and lower portions of 2 intertidal mudflats—1 in the upper Huon Estuary (salinity 4 to 32) and 1 in a marine side-arm of the estuary (salinity 17 to 34)—over 4 seasons. Dark-exposed fluxes of O2 and CO2 were also measured on the u...
