Biodiversity is relevant in all aspects and at all levels of socio-economics. India is rich in biodiversity and its preservation is of utmost importance. Drastic utilization of biodiversity to harness materials and profits for mankind will lead to an imbalance that will affect the overall environment. This must be checked. What we need is an optimal utilization of biodiversity for production of food and nutrition, pharmaceuticals, industrial raw materials and in applications for remediation of industrial pollutants and toxicants. I hope the seminar will discuss all aspects of biodiversity mentioned above and will come up with positive recommendations so that biodiversity is protected, maintained and/or restored. I wish the seminar all success. Prof. Basab Chaudhuri Kolkata Vice-Chancellor November 3rd, 2016 West Bengal State University -6- Message I am glad to know that the Post Graduate Department of Zoology, Barasat Government College is going to organize the National Seminar on “Biodiversity : Exploration, Exploitation, Conservation and Management – Vision and Mission” during 19-20 November, 2016 in Barasat. I am also happy to know that the seminar will bring out an “Abstract Book” containing the articles of the delegates and participants to commemorate the occasion. The theme of the conference is very relevant in the present context and will surely address the key issues related to biodiversity. I congratulate the organizers for hosting the event. I convey my best wishes for grand success of the conference. Prof. Nimai Chandra Saha Burdwan Vice- Chancellor October 24, 2016 University of Burdwan -7- Message It gives me immense pleasure to know that the Department of Zoology, Barasat Government College, West Bengal is organising a UGC sponsored National Seminar on “Biodiversity : Exploration, Exploitation, Conservation and Management – Vision and Mission” during 19-20 November, 2016. Biodiversity is the base of our sustainability. Conservation of biodiversity and rational use of the same, in the backdrop of expanding human population, is therefore a daunting task. The theme of the proposed seminar is very relevant in the present context and will surely help generating awareness among the younger generations, the ways and means to conserve the depleting biodiversity for sustenance of life system on the Earth. I extend my best wishes to the organisers and the participants and hope that the deliberations and interactions in the seminar will help the scholars and students to become the successful custodian of our biodiversity heritage. I wish grand success of the event. Dr. Asok Kanti Sanyal Kolkata Chairman November 4, 2016 West Bengal Biodiversity Board -8- Message Coming at a time when environmental concerns, world over, are gathering credence. The topic of the proposed seminar, ‘Biodiversity : Exploration, Exploitation. Conservation & Management – Vision & Mission’ is very pertinent. The true inventory of biodiversity could be several times higher than what is known today. Lack of trained taxonomists, however, is a serious constraint to achieve this. Conserving what we have today is hampered by lack of management measures including outreach and our ability to predict what would live in India and lack of data relating changes in biodiversity to those of environment. So, the fact that the biodiversity in Indian perspective, its proper assessment and documentation, focus the gap areas for exploration and judicious utilization of bioresources are the main theme of the seminar. The deliberations at this seminar, coming as they will from eminent academicians and experts, are expected to shed light on various aspects of these issues and also offer valuable inputs on the proper harnessing of bioresources without disturbing ecological balances. I am sure our students and teachers will appreciate and enjoy the proceedings of this seminar thoroughly. I wish the organizers of this seminar all success in their endeavour to make this seminar worthwhile. Dr. Subhasis Dutta Kolkata Principal November 12, 2016 Barasat Government College -9- From the Convenor’s Desk People depend on the earth’s living systems for both life and livelihood. Constant technological innovations ushered a radical change in the overall biodiversity and ecosystems with explosive speed. Such activities on our part have brought the entire human race to the brink of an ecological disaster. These deeds have also put even the survival of our future generation into great peril. India has a vast resource of biodiversity. It is a common knowledge that bioresources are important component of progress and the economic activities of a nation. At the same time we are aware that the impediment of a huge population explosion is working at draining resources. Efforts on the sustainable use of these resources also have much to be desired. This is perhaps the greatest challenge faced by the global scientific community. Against this backdrop, the Department of Zoology, Barasat Government College arranged a two- day UGC – sponsored National Seminar entitled “Biodiversity: Exploration, Exploitation, Conservation & Management-Vision & Mission” during 19 – 20 November, 2016 to provide a platform to discuss various aspects about biodiversity, its proper assessment and documentation, focus the gap areas for exploration and judicious utilization of bioresources and hopefully generate the interest and awareness deserved. Not only that, there would be an appeal to the Conservationists, Scientists, NGOs, Civil Society Organisations especially people living close to forests, wetlands, sanctuaries, etc. to contribute their ideas, knowledge and efforts on nature and sustain the precious bioresources of our country which are of immense value and role in the human welfare. We have also aimed to make the seminar more accessible to students while retaining its authority and scope. It is my proud privilege to extend my cordial thanks to the distinguished and celebrated Scientists and Professors, erudite researchers, scholars and students who have joined this National Seminar. I express my heartfelt thanks to Prof. Basab Chaudhuri, Vice-Chancellor, West Bengal State University (Patron), Prof. Namai Chandra Saha, Vice-Chancellor, Burdwan University (Patron & Chief Guest of the seminar), Dr. Asish Kumar Ghosh, Director,
