CASE STUDY ON SUNDARBAN NATIONAL PARK

Improvement of quality of life of this deltaic population by appropriate income generation and proper bio-forest management are the key factors to save their life as well as the mangrove environment of the Sundarban region. They lost their work ability forever. Skip to main content. Our findings indicate that Sundarbans tiger population contains two new closely related mitochondrial lineages, which had not yet been detected previously. South India, and Green: Forest should be forest in the truest sense, but recent evidences showed that the forests are becoming the place of increasing economic activities of the marginal people.

Even after 60 years of independence, Sundarban remains an isolated, remote backward region of the state 7. Thus, morphological distinctiveness of Sundarbans tigers raised questions regarding their conservation status. Impact, Government of India. It could be due to strong philopatry, territoriality among females, and low or no immigration in Sundarbans. He suggested that ESUs should be identified by being reciprocally monophyletic for mtDNA haplotypes and show significant differentiation of allele frequencies at nuclear loci [ 14 ].

However, the median in the skyline plot shows a decrease of the population size beginning about — years ago Fig.

Most of the plot of an internationally acclaimed novelist, Amitav Ghosh ‘s novel, The Hungry Tideis set in the Sundarbans. Recent research suggests that such increase in Between andcontinuous deforestation and land intensity may be attributed to an increase in sea surface reclamation activities have been carried out in the Sundarbans temperature.

KhulnaSatkhiraBagerhat. Previous genetic studies on mainland Bengal tigers have evaluated tiger populations from different landscape complexes or geographic regions in India, such as North, northwest, central, South and northeast, and found moderate to high levels of genetic diversity [ 2122232425262728 ].

A blue-eared kingfisher sighted in the Sundarbans. The fauna of the sanctuary is very diverse with some 40 species of mammals, species of birds and 35 species of reptiles. This page was last edited on 11 Mayat Bengal tiger populations northern Peninsular Sundarbans Northern 0 0.

  IRIS BARSHT THESIS

In order to examine the phylogenetic relationships among haplotypes, all published tiger mtDNA sequences including all extant tiger subspecies were retrieved from GenBank and compared with CLUSTALW in BioEdit, and then manually edited to achieve the best alignment [ 35 ].

Shrimp cultivation had destroyed another 7, hectares 18, acres. They have a thick canopy, and the undergrowth is mostly seedlings of the mangrove trees. Indeed, it is also possible that all these ancient climatic and recent anthropogenic factors combined have shaped the history of present day Indian tiger populations, including the Sundarbans [ 222628 ].

Eco-psychiatry and Environmental Conservation: Study from Sundarban Delta, India

Social Science and Medicine. Hundreds of years of habitation and exploitation have exacted a heavy toll on this ecoregion’s habitat and biodiversity. As a result, high levels of immigration to cities are water from the upstream Ganges and stydy primarily tidal fed. Retrieved from ” https: As per the research conducted it is believed that the Sundarbans II.

Eco-psychiatry and Environmental Conservation: Study from Sundarban Delta, India

Materials and Methods Study area: Our study revealed relatively low levels of genetic variation in Sundarbans tigers, using both mitochondrial sequence and nuclear genetic markers. Introduction Sundarban is the largest intertidal delta in the world and harbours the largest mangrove vegetation. Despite the intense and large-scale exploitation, this still nagional one sundarbn the largest contiguous areas of mangroves in the world.

Thus, it is a region of transition between the freshwater of the rivers originating from the Ganges and the saline water of the Bay of Bengal. The basic unit of management is the compartment. Scientists have predicted that the other low-lying paddy varieties; scientists have discovered the availability of islands could also vanish as sea levels continue to rise.

The mean number of alleles MNA for Sundarbans tigers was 3. DIC values averaged over independent iterations were plotted against Kand the most likely value of K was selected by visually assessing the point at natiknal DIC first reached a plateau and the number of clusters to which individuals were proportionally assigned.

Hoogesteijn RE, Mondolfi H Body mass and skull measurements in four Jaguar populations and observations on their prey base. Since most homes built in the Sundarbans are about how the climate change impacts interact with made natoonal mud and wattle, the organisation chose to use developmental failures.

Genetic diversity and population structure Comparison of bp mitochondrial sequences of the Sundarbans tigers with the sequences from six other tiger subspecies revealed that Sundarbans tigers shared three nucleotide substitutions that were identified as specific or diagnostic to Bengal tiger subspecies.

They also found that the body weight of Sundarbans tigress varies from 75 to 80 kg, which is actually half of the body weight of the tigress in the mainland. Bolstering relevant for those people who live in the critically vulnerable existing livelihood patterns will require research and areas of islands that are submerging or are frequently infrastructural support from Central and State Governments.

Gyaneshwer Chaubey, Academic Editor. The results indicate that residents depend on ecosystem services in two ways. Mol Ecol Notes 7: Ramsar sites in India. The study contended that poor planning on the part of the India and Bangladesh governments coupled with natural ecological changes were forcing the flight of human capital from the region [49] usndarban.
