Relationship between bacterial community composition and bottom-up versus top-down variables in four eutrophic shallow lakes.
Bacterial community composition was monitored in four shallow eutrophic lakes during one year using denaturing gradient gel electrophoresis (DGGE) of PCR-amplified prokaryotic rDNA genes. Of the four lakes investigated, two were of the clearwater type and had dense stands of submerged macrophytes while two others were of the turbid type characterized by the occurrence of phytoplankton blooms. O...
متن کاملThe Importance of Lake Sediments as a Pathway for Microcystin Dynamics in Shallow Eutrophic Lakes
Microcystins are toxins produced by cyanobacteria. They occur in aquatic systems across the world and their occurrence is expected to increase in frequency and magnitude. As microcystins are hazardous to humans and animals, it is essential to understand their fate in aquatic systems in order to control health risks. While the occurrence of microcystins in sediments has been widely reported, the...
متن کاملPhosphorus Models for Eutrophic Lakes
Abstract--A model is developed for a highly eutrophic lake (White Lake, Michigan) which incorporates both the water and sediment systems and considers two forms of phosphorus--particulate and dissolved. Dynamic interactions of phosphorus between sediments and water are quantified by taking account particulate phosphorus sinking to the sediment-water interface and diffusion of dissolved phosphor...
متن کاملCommunity Structure and Environmental Conditions in Florida Shallow Lakes Dominated by Submerged Aquatic Vegetation
Gu, B. and M.V. Hoyer. 2005. Community structure and environmental conditions in Florida shallow lakes dominated by submerged aquatic vegetation. Lake and Reserv. Manage. 21(4):403-410. Florida inland waters are dominated by shallow lakes, many of which support the growth of submerged aquatic vegetation (SAV). We examined the species composition and selected environmental variables of SAV-domin...
متن کاملSymbiotic bacteria as a determinant of plant community structure and plant productivity in dune grassland.
Symbiotic interactions are thought to play a key role in ecosystems. Empirical evidence for the impact of symbiotic bacteria on plant communities is, however, extremely scarce because of experimental constraints. Here, in three complementary experiments, we show that nitrogen-fixing rhizobia bacteria act as a determinant of plant community structure and diversity. Grassland microcosms inoculate...
