Abstract

Limnology is the study of freshwaters. Such limnological studies are helpful in understanding interaction between climate, environmental conditions, and biological processes in the water. Water is vital entity for the existence of all life-forms on the earth, but this precious resource is continuously being threatened by increasing human population as the purpose of the usage of water has been increased such as water abstraction for domestic use, agricultural production, mining, industrial production, power generation and forestry practices. Wetlands being one of the most productive ecosystems in the biosphere, the high microbial and macrophyte productivity occurs at a high rate, which can be attributed partly to an adequate water supply, high organic loading, high sediment nutrients, and organic matter concentrations. Plankton are the microscopic organisms, drifts in the upper photic zone of the oceans, and freshwater water bodies that are unable to swim against a current. Plankton play vital role in the function of any aquatic ecosystem that is energy flow and material flow. Because of their high density, drifting nature, high group or species diversity, and varying stress tolerance, plankton populations are an essential link in the energy transition from producers to consumers. Birds are an excellent taxon to study in order to track global environmental change. Birds are found all over the world, inextricably linked to their environments, sensitive to environmental changes, and their presence might indicate ecosystem function.
