Limnological studies in two tropical Indian aquatic habitats showed that macroinvertebrate communities have greater diversity than other biotic communities present there. Sediment redox potential is found to be an important factor for alteration of macroinvertebrate communities in aquatic bodies. Anthropogenic activities have influenced the changing of sediment redox potential values of the studied sites and there by affected the macroinvertebrate communities.
Studies on the biodiversity on Kuntbhyog Lake (Himachal Pradesh) were made on species composition and population dynamics of phytoplankton, zooplankton, nekton, productivity in relation to seasonal variations in physico-chemical characteristics of water. Among phytoplankton, members of Bacillariophyceae and Chlorophyceae constituted the dominant group, whereas Cyanophyceae and Euglenophyceae were the subdominant component. Among zooplankton, Rotifera and Arthropoda formed the dominant group, whereas Protozoa...
We analysed the fluctuations of the limnological variables and phytoplankton structure in two shallow lakes located in an urban ecological reserve from Buenos Aires city (Reserva Costanera Sur) during a complete hydrological cycle. The results of this investigation showed that the changes in the water level strongly affect the limnological variables and the structure of the phytoplankton communities. In both shallow lakes, the water level was inversely correlated with conductivity (p Keywords: urban reserves,...
Landscape limnology is the spatially-explicit study of lakes, streams, and wetlands as they interact with the freshwater, terrestrial, and human landscapes to determine the effects of pattern on ecosystem processes across temporal and spatial scales. The terrestrial component represents spatial hierarchies of landscape features that influence what materials, whether solutes or organisms, are transported to aquatic systems; aquatic connections represent how these materials are...
Abstract The limnological record of human impact on catchment land cover and on lake sedimentation during the historical period has been established for Pinto Lake in Central Coastal California. In addition, the sedimentary record of the ‘pre-impact’ condition preserves evidence of a climatic control on the nature of lake sedimentation. Chronological marker horizons have been determined using pollen data in combination with the documented land-use history and introductions of exotic species. Further chronological...
