Seasonal changes in icefish diel feeding patterns in Lake Chaohu, a large shallow eutrophic lake of China
Seasonal changes in the diel feeding patterns of the zooplanktivorous icefish (Neosalanx taihuensis), which is an endemic species of China, were studied in the large, shallow eutrophic Lake Chaohu of China during the autumn of 2002 and summer of 2003. The results of the diel feeding rhythm indicate that icefish is a visual particulate feeder. There were large differences in diet composition and...

متن کاملEffects of historical lake level and land use on sediment and phosphorus accumulation rates in Lake Kinneret.
Current paradigms of reservoir ontogeny suggest that water-level fluctuations may increase sedimentary nutrient release, causing long-term eutrophication of water bodies formed by dryland flooding. Less is known of the changes in nutrient status following conversion of natural lakes into reservoirs. Here, we use historical hydrological and limnological data and paleolimnological records of sedi...
متن کاملOrganic phosphorus species in surface sediments of a large, shallow, eutrophic lake, Lake Taihu, China.
Organic phosphorus (P) fractions in surface sediments from a large shallow, eutrophic Lake Taihu, China, were extracted with 0.1 M NaOH after pre-treatment of the sediments with a solution composed of 0.1 M EDTA and 2% (w/v) Na(2)S(2)O(4). Composition of organic P in the extracts was then characterized by (31)P nuclear magnetic resonance spectroscopy ((31)P NMR). Several P species, including ph...
متن کاملInteractions between sediment resuspension and sediment quality decrease the TN : TP ratio in a shallow lake
The relative contributions of sediment resuspension and external nutrient loading to seasonal fluctuations of the total nitrogen to total phosphorus (TN : TP) ratio in the water column of the shallow Kirkkojärvi basin were studied. In May, the TN : TP mass ratio was above 30, but it decreased to below 10 in July–August. In October, the ratio increased again. Water quality was regulated by exter...
