Abstract:
... In Pool 19 of the Mississippi River, the fingernail clam, Sphaerium transversum, appears to feed non—selectively on phytoplankton, although green algae were in higher percentages in guts than in plankton samples. Diatoms were of paramount importance in clam guts and water samples during most sampling periods, especially from December to April when mean monthly water temperatures were less than 4 d ...

A third watershed of 203 ha was not logged but remained as a control. Pre—logging and post—logging oxygen ...

Abstract:
... Recovery of a desert stream after an intense flash flooding event is described as a model of temporal succession in lotic ecosystems. A late summer flood in Sycamore Creek, Arizona, virtually eliminated algae and reduced invertebrate standing crop by 98%. Physical and morphometric conditions typical of the preflood period were restored in 2 d and the biota recovered in 2—3 wk. Algal communities re ...

The creation of Lake Nasser, due to the impoundment of the River Nile in Southern Egypt, was accompanied by alterations in the environmental conditions that consequently affect the biota. Such alterations lead to corresponding changes in the diversity, abundance and distribution of the phytoplankton community. Therefore, the phytoplank ...

Water transparency (as determined by Secchi disc depth), plant nutrients, chlorophyll a concentrations and phytoplankton were examined. High water transparency indicated that the euphotic zone extended over the majority of the lake and may, at times, have reached the deepest parts of the lake. Silic ...

Here, we exploit recent advances in plankton models to develop competition theory that predicts how changes in turbulent mixing affect competition for light between buoyant and sinking phytoplankton species. We compared the model predictions with a lake experiment, in which the turbulence s ...

Abstract:
... Biomanipulation measures in lakes, taken to diminish algal blooms, have mainly been restricted to the reduction of zooplanktivorous fish with the aim to stimulate the grazing pressure by native filter feeders such as Daphnia. However, larger filter feeders like the exotic zebra mussel, Dreissena polymorpha, have been suggested as an optional tool because of their high filtering capacity. We compar ...

In the present work, the eutrophied Vela Lake (Central Portugal), used for recreational purposes and as a water source for agriculture, was monitored every fortnight between 2000 and 2001. Phytoplankton diversity and densities were measured and corr ...

Sestonic FA composition in two lakes moderately differed, whereas levels of diatom FA markers were higher in Lake Shunet and of Cyanobacteria and green alg ...

We show that despite the high optical, mechanistic, and hydrodynamic stress for the cells while sorted, most of the targeted populations could be isolated and grew in mixed culture media subsequent to sorting. Forty-five phytoplankton taxa were i ...

However, there is a controversy about its use as an indicator of P deficiency in natural phytoplankton community inferred by such an “induction-repression” mechanism. Size-fractionation of alkaline phosphatase activity (APA), soluble reactive phosphorus (SRP) concentration, alg ...

Getting to know the response of different groups of aquatic organisms tested in altered thermal environments to environmental conditions makes it possible to understand processes of adaptation and limitation factors such as temperature and light. Field sites were located in three thermally abnormal lakes (cooling system of power plants), in eastern part of Wielkopolska region (western Poland): Pąt ...

Abstract:
... Temporal and spatial variations in the phytoplankton community and environmental variables were investigated from February to July 2014, in the upper lake of Shengjin Lake, China. We identified 192 species of phytoplankton belonging to 8 phyla and 84 genera, of which 46.4 % of Chlorophyta, 29.2 % of Bacillariophyta, and 12.5 % of Cyanophyta. There were 14 predominant species. Marked temporal and s ...

There is a need for rapid and cost-effective tools to survey benthic cyanobacteria. In this study we assessed the performance of the BenthoTorch, a fluorometric probe that provides in situ estimations of cyanobacteria, diatoms and ...

In this paper, we give an overview of studies that report on the results of this remedy. Generally, artificial mixing causes an increase in the oxygen content of the water, an increase in the temperature in the deep layers but a decrease in the upper layers, while t ...
