Research Problem: a) Title of Thesis : “Seasonal Variations in Physico-Chemical Regime of Pond Ecosystem” b) Brief Outline of Work: Ecosystem is a basic structural and functional unit composed of biotic and abiotic components interrelating and interacting upon each other with unidirectional flow of energy in a particular unit of space. A pond is a self sufficient and self regulating ecosystem. Physico chemical regime includes physical and chemical characteristics. It is closely related to

inundated by water cyclically‚ intermittently or permanently and can have fresh‚ brackish or salt water. The main wetland types include swamps‚ marshes‚ bogs‚ and fens. Wetlands are the link between land and water and are some of the most productive ecosystems in the world. Depending on the type of wetland‚ it may be filled mostly with trees‚ grasses‚ shrubs or moss. An area doesn’t need to be permanently wet to qualify as a wetland. It just needs to be wet long enough for its plants and animals to be

Fire is a major factor in our ecosystem‚ both good and bad‚ that is influenced by climate. It can cause carbon dioxide to have a direct effect on vegetation‚ and land use‚ and in turn‚ affect landscape pattern processes. Fire in the Earth’s ecosystems is a natural occurrence that is vital in keeping the flow of natural cycles healthy and efficient. Natural causes of bush fires has played significant role in shaping the ecosystems‚ such as certain plant life being more susceptible to harsh‚ scorching

The Everglades‚ a "famous region in Southern Florida"‚ are a wetland ecosystem home to tropical and marshland plant and animal species. The Everglades which are a national park‚ are often thought of " a rather unpleasant place: creepy and shadowy‚ muddy‚ overrun with snakes and insect." They are also thought of as irrelevant and not important.

Conceptual Framework of Ecotourism Ecotourism is defined as a “purposeful travel to natural areas to understand the culture and natural history of the environment‚ taking care not to alter the integrity of the ecosystem‚ while producing economic opportunities that make the conservation of natural resources beneficial to local people” (McCormick‚ 1994). Based on this definition‚ the conceptual framework was formulated. The operationalization of the framework included an assessment procedure

chemicals get into the atmosphere they will harm any environment. There are several environmental effects of acid rain. Acid rain can harm an ecosystem very little or very badly. One effect is runoff from the acidic rain which can flow into streams‚ lakes‚ and other bodies of water. This can cause the water to be more acidic. In many sensitive water ecosystems this can kill or harm several fish and other organisms. The acids in the water from the runoff can also reduce nutrient levels. This will also
