Natural calamities by cyclones, forest fire, grazing and browsing are alarming in causing damage to the flora of the Pulicat lake Basha et al.
This also causes rapid shrinking of water spread area of the lagoon. Various useful tree species were found only in the reserve forest and seldom available in the urban village. The plant species are chosen with the twin goal of raising the bio-shields and deriving livelihood to the local communities, creating awareness among local resident about the numerous benefits imparted by the coastal ecosystem on mankind.
Nanda Kumar NV Conclusion So far as the Pulicat Lake is concerned, management of the lake mouth is crucial for the health and prosperity of the eco- system.
Low immigration would maintain this relationship, though species would change over time. Aquatic and Avian fauna of Pulicat Brackish water lake is studied by Nandakumar et. Basha He is working in Department of Botany, V. Research Article the Sriharikota cyclone of that had its eye right on the northern part of Sriharikota Island, and created cataclysmic changes on the lake ecosystem.
They develop pneumatophores in response to oxygen deficient conditions. Consensus among the Customary Land members and integration of traditional ecological knowledge are recognized as key factors for successful conservation [ 20 - 22 ].
Direct way is in increasing agricultural productivity which supports the existence of life on the Earth. The wider and the deeper lake mouth is and the longer it opens into the sea, during the year, the more will be the vital inputs in the sea, like nutrients, oxygen, plankton and fish-seed, which are the very basis of life and food chains in this lake, Keeping the lake mouth open right round the year and opening of the extra mouth in the north, will surely enhance the productivity and food chains in the lake.
It has maximum effect on Biotic component of the ecosystem. In aquatic systems, lakes and even isolated coral reefs fit neatly into the theory, in many cases with proximity to a continental shelf a critical factor. Rajya Lakshmi Currently doing Ph. Urbanization threatened this human—forest interaction.
Thus, conservation of biodiversity has gained prime consideration all over the world since the earth summit at Rio de Janeiro in Herbaria-specimens are preserved at N.
Out of the total area of the lake, about km2 in the southern part is active where as the rest of the lake are in its northern part is desiccated and now it appears more or less like a mudflat.
Jayadevexamined 50 species of fish out of which 16 species had macro parasites. Species loss would be huge even if the niches remain more or less intact. The first and foremost process in ascertaining the biodiversity is the taxonomic treatment of living organisms.
P, India 3 Department of Botany, S. They help in removing pollution, coastal erosion and protection from saline water intrusion and stroms. Because of their instability in terms of environmental conditions, extinction rates don't relate to area on small islands.
Region of pulicat lake includes salt marshes, canals and mangroves. Research Article system and the trunks provided. Brackish water is more saltier than fresh water and less saltier than sea water.
Many animal and plant groups were tested alongside a broad range of archipelago types. Two attributes of biodiversity according to International Conservation Point of view are species richness The number of species in an area and Endemism Species restricted to a given region and occur no where else.
In contrast, some top-down conservation decisions by agents outside of the communities have ignored local needs, causing disputes with local people and achieving limited success. Invasive phytoplankton species of Spirulina major, Oscillatoria sps. The greater Flamingo about 15, of them spends the winter on this Lake.
Fly ash is especially harmful as it can be inhaled and leads to permanent respiratory disorder, dermatitis, asthma, bronchitis and Cancer. It grows above and below the ground level and provide a habitat for fish, shrimp and other aquatic species and also provide forage for waterfowl.
It has serious impact on aquaculture development. Special attention was paid to how local people depend on biodiversity and how traditional human modifications of forest contribute to biodiversity conservation.
Filtering large quantities of detritus, suspended in water. Common shrubs like Azima tetracantha, Cassia auriculata, Excoecaria agallocha, Gmelina asiatica, Jatropha gossypifolia, Lawsonia inermes, Maytenus emarginatus, Pandanus tectoreus, Salvodora persica, Zyziphus mauritiana etc.
Thousands of acres of land have been cleared for three projects that will progressively damage the ecosystem stretching across 40 km from Ennore to Pulicat.
Marine chemicals and salt manufacturing industries and Shrimp farming on the eastern part of the lagoon affected the Pulicat Bird Sanctuary along with disturbing the livelihood of fishermen and agricultural workers.Floristic Studies Of Sriharikota, Irkkam, Venadu And Pernadu Islands Of Pulicat Lake Of Spsr Nellore District Â€“ Andhra Pradesh; Floristic Studies Of Sriharikota, Irkkam, Venadu And Pernadu Islands Of Pulicat Lake Of Spsr Nellore District Â€“ Andhra Pradesh $ Island species are often evolutionarily distinctive and highly vulnerable to novel disturbances, particularly invasive species.
Invasive species, which primarily spread around the globe via human transportation systems, are a leading cause of extinctions on islands and biodiversity loss globally.
15 Conservation on an Island Biodiversity Hotspot Overview Students read about four forest areas being considered for conservation on the island of Kapikua, and use the informa. Island species are also unique in their vulnerability: of the recorded animal extinctions in the last years, about half were island species.
Over the past century, island biodiversity has been subject to intense pressure from invasive alien species, habitat change and over-exploitation, and, increasingly, from climate change and pollution. Although global biodiversity is threatened on the whole, islands have been especially hard hit by threats such as invasive species, which alter ecosystem dynamics and harm biodiversity.
Indeed, islands are home to 41% of the Earth’s highly threatened animals, and preventing extinctions of their native species is possible.
Conservation interventions on islands to remove the threat of invasive species have. Background. Solomon Islands is a high-priority area for biodiversity conservation because of its location in the east Melanesian Islands biodiversity hotspot [1,2].The rich biological diversity there stems from the fact that its more than islands, covering 28, km 2, have never been in land contact with the Asian continent or New Guinea Island.Download
