‘Values of biodiversity’ are classified as three main types. 1. Resources 2. Potential resources 3. Contributory factors. For example, the biological materials are consumed in markets which are valued for their recreational or aesthetic purposes. It is called as Resources category. Whereas, an opportunities for the discovery of new product is called as Potential resources. In last part, the functional role in ecosystem like ‘Niche’ is called as Contributory factors.

"Biocenosis" means different species like plants, animals, microbes and human beings interact to form a beautiful community or eco-system. This interaction between living organisms in the eco-system called as biotic factors. Species also dependent upon abiotic factors. The main function is flow of energy from one trophic level to another level transferred. From this concept, ecosystem sustain the structure like functional unit.

I have stressed the importance of Marine Biodiversity, particularly "Microbial community of intertidal zone" in Rameshewaram area, Ramanathapuram Dt. It is a very harsh living environment. They are constantly facing challenges such as salinity, wind, sunlight, predators and strong water currents. It helps with these difficulties many organisms have “special adaptation” features.

An endangered species is a native species that faces a significant risk of extinction. Such species may be declining in number due to threats such as habitat destruction, climate change and pressure from invasive species. The flora of India is one of the richest in the world due to the country's wide range of climate, topology, and environment. There are over 15,000 species of flowering plants in India which account for 6% of all plant species in the world. Many plant species are being destroyed. Roughly 1/4 of all plant species in the world are at risk of being endangered or going extinct. The combination of global warming and habitat destruction are the sole reason for the disappearance of many plants. The following plants are very threatened in Tamilnadu: Acacia planifrons (Umbrella tree), Abutilon indicum, (Indian mallow), Chlorophytum tuberosum, (Musli) and Chlorophytum malabaricum (Malabar lily).

“Keystone Species” are keep the ecosystem in balance. If suppose loss one such species in the eco-system, entirely collapse the total eco-system and further extended to the near eco-system. Keystone species maintain long-term sustainability. Take for example humming birds. It is vital in the pollination processes.  Another good example is Grey wolf. Hence, the present movement is preservation and restoration of keystone species is very essential. Recently, Uma Ramakrishnan, National Centre for Biological Science, Bangalore has pointed out, Pikas are keystone species. Pikas mostly habitat in Himalayan ecosystem. And Black Clam is another keystone species. Black Clam is highly available in Vembanad Lake. Such species indirectly help to the fisheries field. Now, black clam is declined by human activities in the form commercial business. In terrestrial ecosystem, number of animals act as keystone species. Such as butterfly, earthworm, bees, birds and ants etc. Sometime, buffaloes dung are useful to disseminate the rare seeds. Hence, we aware about the Keystone Species for future generation.

“Species diversity” means the whole of diversity life. It includes human-beings, animals, plants, fungi, bacteria, protozoa and viruses. Very rare and endemic species diversity has only found in the specific geographical region. The best example is Australia Kangaroo species. In the biosphere such kind of species not observed in any other parts world. And another best example is radiated tortoise groups found only in the Madagascar islands. Unicellular organisms are invisible to naked eye. Such as bacteria, archaea and protists. Cyano-bacteria is photosynthetic oxyntic groups. It is subclass of bacteria. It has found throughout the world. It is a ubiquitous nature. In archaea is very unfamiliar groups. It has found in hydrothermal springs of ocean. They do not have chlorophyll. From this lecture, I have motivated the students to know the taxonomical system of animals, plants and microbes.

“Bird Biodiversity” in Tamilnadu is under the threatened condition said by Bombay Natural History Society (BNHS) Mumbai. They announced that near 18 species are endangered. They were identified from the Important Bird and Biodiversity Areas (IBAs). They notified that habitat destruction, agricultural intensification, industrialization and urbanization factors. These are the main causes for biodiversity loss. They also pointed out few of vulture groups such as White Vulture, Long-billed Vulture, Red-headed Vulture and Spoon- billed sandpiper are critically endangered. Spoon-billed sandpiper is not confirmed in Tamilnadu areas. Cheyyur lagoon, Kanchipuram District is now recognized by Wildlife Society of India. This wetland has supported by near 80 variety of birds. But this wetland is problem in nature, because near to the Thermal Plant. Another one place Megamalai near to the Theni District has recognized. Bird Life International (BLI) has framed certain essential criteria for IBAs. They are 1. Endangered species 2. Endemic nature 3. Biome 4. Near 20.000 water birds. In this juncture, I have sponsored the environmental related books to the students of XI and IX STD. They won the contest regarding environmental questions. Peter Sir, has assisted the all activities for this programme and other faculty members were participated.

“Biodiversity in Education” is one of the new discipline come under the branch of conservation biology subject. There are many animals and plants currently under threats of human activities as indicated by IUCN Red List recently. In that list, coral reefs are included. Corals are a group of living creatures whose extinction rates are rising in every movement. Paramo is one of the beautiful tundra ecosystem in the World. Now, consider as sacred groves. And another kind of beautiful sacred grave is Monkey forest sanctuary in Indonesia. These are more valuable plants and animals occupied in that place. In marine ecosystem, number of living creatures are wondered. Example Leafy sea dragon is one of the beautiful deep sea animal. It creatures is just like leaf structure. Earth’s 70% surface covers ocean. This ocean have natural carbon. So it is called as Blue planet. Further, I have emphasized the importance of pedagogical techniques for biodiversity and environmental education. Here, infusion model and interdisciplinary model are recommended but domain selection is very important. Level one is an ecological foundations, level two is the conceptual awareness on biodiversity issues and values, level third is an investigation and evaluation processes and fourth level is action skills requires for training.

“Coral reefs” are formed by calcium carbonate materials which is secreted by corals. Corals also called as rain forest of the sea. It is very good shelter for many kinds of other marine organisms. Due to climate changes and man-made activities, it becomes under the endangered list. Dr. Venkataraman, Director, Zoological Survey of India said that Snowflake corals (Soft Corals) posing serious threat to the coral reef colonies of Gulf of Mannar and Andaman and Nicobar Islands, India. IUCN also pointed out, it is life supporting system and it protects from sea erosion. This invasive species of soft corals high fecundity and it may grows 20-30 meters length. Such kind of corals called as Bio-invasion species. Translocation by ship is a major problem. We have limited facility for this bio-invasion species. Hence, we shall need an awareness for such kind of bio-invasion species. In general, coral reefs give a place for other rare and endangered species.

“Natural environment” is also called as Habitat. Nowadays, habitat destruction is one of the major issue in our biodiversity loss. It includes, abiotic and biotic factors. Both factors interact to form an ecological succession. Due to the present modernization, man occupied most of the habitats of living organism. It extents their own niche. Best an example is man occupied in elephant habitat. Hence, mitigating the issues between the man and animal is very essential one. And further, I have given the importance of ecotourism. It is emerging as a popular approach to protect natural areas throughout the world. It focuses on local cultures, wilderness adventures, volunteering, personal growth and learning new ways to live. It is typically defined as travel to destinations where the flora, fauna, and cultural heritage are the primary attractions. Responsible ecotourism includes programs that minimize the adverse effects of traditional tourism on the natural environment and enhance the cultural integrity of local people (Ceballos-Lascurain, 1996). We will be encouraging this concept to our people.

A special lecture on "Biodiversity Conservation Strategies" at Kongu College of Arts and Science, Karur-Dt. (21.08.2017).

“Conservation strategies” are four main groups for Biodiversity Wealth. First is maintain landscapes and remove threats from the particular areas in any ecosystem or biomes. Second is reinstating the critical eco-system or particular community. Best example is pollination processes. Third is recover of threatened species from the particular eco-system or from the wildlife eco-system. Fourth is controlling threatened species like adapting the new climate changes. These four strategies are recommended by foreign people. Whereas, in India, so different. Here, there are two types of strategies are followed. One is in-situ conservation. Here, Protected Areas (PA) is superior one. It have many sub-units like National Parks, Sanctuaries and Biosphere Reserves. In another part, ex-situ conservation. Here, Sacred Groves, Seen Bank, Cryopreservation, Zoo and Botanical gardens. From this special lecture, I have stressed the importance of conservation techniques and an individual’s responsibility is also a vital role for conservation process.

“Beneficial of Microbial Diversity” has explained by me at Govt. Boys Higher Secondary School, Velliyanai, Karur-Dt. Here, I have pointed out the importance of microbial communities such as protozoan groups, flagellates, radiolarians, hypotrichs and other larval forms. In this function, students are highly motivated to ask the questions related to the microbial communities. Protozoans are single celled organism. In our ocean they are number of variety of organisms are available. Few of protozoans were identified by National Institute of Oceanography (NIO), Goa, India. I have said that around 107 species of protozoan groups were identified by me in the Gulf of Mannar, India. This is the first report from Rameshewaram areas, Tamilnadu, India, after the B.L Bhatia (1936) manual. From this speech, I have concluded that the importance and beneficial of microbes are available from our Gulf of Mannar areas, India. Such kinds may be very useful to medicinal values and essential for microbial loop system of ocean.
