Answer 1

Answer:

Explanation:

A team of scientists from the University of Delhi and Zoological Survey of India (ZSI) discovered a new species of frog in Arunachal Pradesh and named it Microhyla eos, according to a statement.

Microhyla are a group of narrow-mouthed frogs (subfamily Microhylinae) that is primarily and widely distributed in Asia. Commonly known as 'Rice Frogs' or 'Chorus Frogs', the genus currently comprises of 49 recognised species.

The new frog was discovered from riparian habitats in a primary evergreen forest in the Namdapha Tiger Reserve of the state, which is also the eastern-most protected area in the country.

The frog was confirmed to represent a distinct new species after detailed comparison of both, DNA and morphology, with all previously known members of the group found across South, Southeast, and East Asia.

Since Arunachal Pradesh is popularly known as ‘the land of rising sun’ or ‘the land of dawn-lit mountains’, the new species has been named as eos, after the mythological Greek goddess of dawn.

Scientific Activities

1. Technology Development

• Improving Traditional Water Mills for Income Generation and Improvement of Livelihood of Tribals in Arunachal Pradesh

This activity was taken on project mode with the basic objective to improve the efficiency of the traditional water mills and also generate electricity for better livelihood. Water Mills have been used from time immemorial in the State for grinding wheat, rice, maize etc. Efficiency of Traditional water mill is very less hydraulically as locally available materials like wooden shaft, wooden blade, wooden chute and stone were used. In the absence of appropriate technology, water mills were never used for any other purpose on which they run. With the technology intervention the efficiency will improve and also generate electricity.

• Installation of Micro Hydel projects of 2 X 100 kW & 3 X 100 kW capacities at different selected locations of Arunachal Pradesh

These projects were implemented on demo R & D mode with the basic objective to provide electricity to the remote villages of Arunachal Pradesh for a better livelihood through replication of the cross flow turbine technology developed by IISC, Bangalore especially designed for low head projects.The cross flow technology can be replicated in the entire Himalayan region for generation of electricity in remote locations.

• Scientific Evaluation of Water Purification System (Selection, Installation and Assessment)

The project was implemented with the basic objective towards assessment of performance of different types of water purification systems/ technologies commercially available based on ultra filtration, adsorption, reverse osmosis, Ion exchange, resin technology, UV, Ozonation etc. for providing safe drinking water in Schools/ Institution. Through this project, new facilities have been created in the form of water storage tanks for both raw and treated, filtered safe drinking water in the schools. Installation of suitable and need based type of water purification units have addressed the much needed basic requirement of having safe drinking water available to the students, teachers in the remote schools..

• Banana and Pineapple Fibre extraction and processing.

The use of “Banana” fiber for textile and other purpose as natural material is a new concept for India.Wild banana is abundant and are available almost free of cost in Arunachal Pradesh which can be sustainably exploited income generation and self employment for the youths of the State. The project is being implemented to facilitate meaningful utilization, value addition of otherwise least important, resources discarded as wastes through demonstration and application of appropriate technologies available.

• Installation of Geo-thermal based Heating and Cooling System at Science Centre, Itanagar.  

Arunachal Pradesh in its attempt to adopt to the fast growth of technology in India has implemented the geothermal-based heating and cooling system, a pilot project in collaboration with The Energy & Resources Institute (TERI) in Arunachal Pradesh Science Centre (APSC), Itanagar that offers more than 30% energy saving, cooling and heating facility without loss of water

Discoveries

• This is the first record of the tortoise in India, taking the count to five and the non-marine chelonian count to 29. Chelonian is an order of reptile that includes turtles, terrapins and tortoises.

• Three new species of tiny frogs have been discovered in Arunachal Pradesh.The new species discovered from Talle Valley Wildlife Sanctuary (WLS) have been named as ‘Liurana himalayana’, ‘Liurana indica’ and ‘Liurana minuta’,

• Arunachal Pit-viper (Trimeresurus arunachalensis), basing the zoological name on the geographical area, is the new name given to this newly discovered species after a team of experts came across a lone brown pitviper, visibly distinct from the other brown pitvipers of the region.
• A new species of fish has been discovered in Arunachal Pradesh. The fish species is named as Schizothorax sikusirumensis. The name of this fish species has been derived from the name of the rivers where it was found. .
• A group of five butterfly and moth researchers have found a new moth species and rediscovered another not seen in India in over a century at the Tale Wildlife Sanctuary (TWS) in Arunachal Pradesh.“The new moth species that we discovered belongs to the rare genus ‘Metallolophia’, of which only 16 species are known globally and three in India.
