Grey Slender Loris Unique Species of Ayyalur Reserve Forest, Dindigul-Dt. Now Under the IUCN Red List. (17.03.19)


Loris lydekkerianus
Grey Slender Loris is one of the rare and endangered primate mammal found in the Ayyalur Reserve Forest in Dindigul, Tamilnadu, India.  The species name is Loris lydekkerianus. Lorises are unique creatures always found in the trees of Eastern Ghats. In IUCN category it Least Concerned (LC). In tamil language, we called as Thevangu. People of Tamilnadu and some communities believed that loris have medicinal properties. But in scientifically not found any medicinal values. They confirm declined by human activities (Superstition). Very specially, loris’s blood have been applied for their ritual function. This animal nature is sluggish movement and with the hand and tongue captured some insects as food source. We need to conserve!

A special talk on "Life Lives On The Edge - The Biodiversity" at St. Mary's Higher Secondary School, Dindigul-Dt. (04.05.2018).

‘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.

A special lecture on "Biodiversity-An Exploration of Life" at RVS College of Education, Dindigul-Dt. (13.03.2018).

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.
