Ground water is a significant source for drinking, agricultural and aquaculture purposes in Godavari region. Groundwater if contaminated due to manmade activities cause concern on environment and human health. The aim of the present study is to review the impact of aquaculture on environment briefly and to assess the ground water quality in East Godavari District. Aquaculture activities are major impact on water resources-they are physical, chemical and biological.

Protected areas (PAs) are inviolate and invaluable landscapes that promote the in situ conservation of endangered, threatened and rare species. Accordingly, and in keeping with this definition, PA managers ensure that PAs are free from fire, poaching, grazing, non-timber forest products collection, mining, etc. In India, following the Indian Wildlife (Protection) Act (1972), there are

Identifying mechanisms governing the establishment and spread of invasive species is a fundamental challenge in invasion biology. Because species invasions are frequently observed only after the species presents an environmental threat, research identifying the contributing agents to dispersal and subsequent spread are confined to retrograde observations.

About 3,000 reindeer on an island near Antarctica are to be slaughtered to stop damage to the environment by the descendants of a tiny herd introduced a century ago for food by Norwegian whale hunt

Forest biodiversity in the Eastern Ghats is undergoing a tremendous change.

Invasive species are regarded as one of the largest threats to biodiversity but little is known about the invasion of exotic plants into the tropical forest. The per cent grass availability in gaur (Bos gaurus H. Smith, 1827) foraging areas in three different habitats namely dry deciduous forest, moist deciduous forest and thorn forest in relation to weed category areas viz., Lantana camara invasion areas, Chromolaena odorata invasion areas, 'both weeds invasion' and 'weed-free' areas were investigated in Mudumalai Tiger Reserve between November 2003 and April 2004.

Invasion of lionfish Pterois volitans and other reef fishes in the Vellar estuary, Parangipettai (lat.11°29′N, long. 79°46′E) southeast coast of India, is a cause of concern as it may affect the local fishing communities and the estuarine ecological conditions.

In the context of Alien Invasive Species (AIS) assuming worldwide importance as being the second most important irreversible impact on landscapes next to habitat destruction, the paper assesses their threat to the forests of Kerala.

There are various drivers of degradation those are adversely impacting the ecosystems and in turn affecting ecosystem services. Ironically, the growth economy and unsustainable policies are leading to erosion of the very base – biodiversity and ecosystems.

We coordinated biogeographical comparisons of the impacts of an exotic invasive tree in its native and non-native ranges with a congeneric comparison in the non-native range. Prosopis juliflora is taxonomically complicated and with P. pallida forms the P. juliflora complex. Thus we sampled P. juliflora in its native Venezuela, and also located two field sites in Peru, the native range of Prosopis pallida. Canopies of Prosopis juliflora, a native of the New World but an invader in many other regions, had facilitative effects on the diversity of other species in its native Venezuela, and P.
