“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.

A special lecture on "Our Valuable Heritage-The Biodiversity" at Muthayammal College of Education, Rasipuram. Salem-Dt.(31.01.2018).
“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.

A special lecture on "Biodiversity as a Goal of Environmental Education" at Arasu College of Education for Women, Karur-Dt. (27.01.2018).
“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.
A special talk on "Biodiversity Conservation" at Govt. Hr.Sec. School, Velliyanai, Karur-Dt. (10.08.2017)
“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.
Research Article from IJGMS-CSIR, India. (01.06.2013).
“Microzooplankton” such as protozoans, crustaceans, rotatorians, and larval forms have been studied in the Gulf of Mannar islands, India. Abundance, distribution and species composition were carried out in these areas. Parameters of different seasonal variation being analysed. In species composition, species have been adapted a wide range of changes. They have been recorded. This is due to may be temperature change or salinity or may be DO or BOD variations. From this analysis, the investigator has found tremendous species diversity of protozoan groups were recorded. Such kind of varieties not observed from foreign countries. This measurement proved by statistical procedures with spss package analysis. From this research, very peculiar species of protozoan ciliates have been identified in between of endangered corals and poriferas.
