Today, Aquatic Microbial Ecology as a discipline is much broader than plankton ecology ever was, for it includes not only oceans and freshwaters but also benthic, interstitial and groundwater systems. However, there were no significant changes in microcosms with bulk counterparts of nanoparticles, as well as no accumulation of aluminum oxide on the surface, nor in the mitochondria of D. rushmore, the royal tennenbaums, the life aquatic with steve zissou. P., 'Results of Interlaboratory Testing of the Standardized Aquatic Microcosm Protocol,' this. This was conceptualized moving historically from the so-called water desert to microcosm to ecosystem.
Cytochemical analysis of Daphnia magna crustacean cells showed accumulation of nanoparticles on the surface of organisms and in their mitochondria, causing swelling of mitochondrial cristae, as well as disturbances of their system with a clear matrix in the centre of organelles. Furthermore, exposure to nanoparticles contributed to the increase of the activity of antioxidative enzymes of benthos. The 28 d experiment showed negative effects of nano-Al2O3 on aquatic ecosystems, as evidenced by reduced biodiversity of microbenthic and plankton organisms. The study examined structural and functional changes in the microcosm, inhabited by representatives of all trophic levels of the aquatic food chain, in the presence of aluminum oxide nanoparticles and their bulk counterparts (100 mg/L). Aquatic mesocosms and microcosms (cosms) are model experimental systems, designed to be representative of specific ecosystems, e.g., small freshwater ponds or lakes. This microcosm system was designed to support modelling approaches of the catchment scale and gain insights into the fate of pesticides simulating a large.
