The Kanger valley rock gecko Hemidactylus kangerensis is the newest addition to India’s lizard species.

  • Researchers, led by Zeeshan Mirza of the National Centre for Biological Sciences, discovered the gecko from Chhattisgarh’s KangerGhati National Park.

  • Though named after this park, the species is also found in Jagdalpur and Sukma in Chhattisgarh and in Khamman in the adjoining State of Telangana, which are part of the Eastern Ghats.

  • The distinct black-bordered beige bands that the new species sports right from its neck to its tail tip and specific scales on its thighs (which are visible only on closer inspection) set the Kanger valley rock gecko apart from the commonly-found rock gecko.

  • Growing to over eight inches long, the adult Kanger valley rock gecko is fairly large. The researchers found them in abandoned houses in the national park and juveniles on termite mounds and tree trunks. Though several researchers and reptile buffs had spotted the species before, they had mistaken it for the commonly-found rock gecko which it resembles.



      1. Most Pollution-Linked Deaths Occur In India

    • With 2.51 million deaths in 2015, India has been ranked No. 1 in pollution related deaths, according to a report by The Lancet Commission on pollution and health.

    • China recorded the second highest number of such deaths (1.8 million). India accounted for about 28 per cent of an estimated nine million pollution linked deaths worldwide in 2015.

    • The Lancet Commission on pollution and health is a two-year project in which more than 40 international health and environmental authors led by environmental scientist Philip Landrigan were involved.

    • At 6.5 million premature deaths globally, air pollution was the leading cause of deaths in 2015. Among the world’s 10 most populous countries that year, the largest increase in numbers of pollution related deaths were seen in India and Bangladesh.But the absolute number of air pollution deaths in Bangladesh was only 0.2 million.

    • With 1.58 million, China had the second-highest number of air pollution deaths after India (1.81 million). But the number of water pollution deaths in China was only about 34,000, compared to 0.64 million in the case of India.

    • Nearly 25% of all deaths in India in 2015 were caused by pollution; Pakistan, China, Bangladesh, and Kenya too reported that one in four deaths were caused by pollution.

    • In the case of air pollution, the number of deaths in India from ambient air pollution was 1.09 million, while deaths from household air pollution from solid fuels were 0.97 million. In the case of water pollution, 0.5 million deaths were caused by unsafe water source, while unsafe sanitation caused 0.32 million deaths.



    • Deaths from air pollution were a result of diseases such as heart disease, stroke, lung cancer, and chronic obstructive pulmonary disease (COPD).

    • Pollution has been responsible for the most non-communicable disease deaths. Pollution is responsible for more deaths than a high-sodium diet (4·1 million), obesity (4·0 million), alcohol (2·3 million), road accidents (1·4 million), or child and maternal malnutrition (1·4 million).

    • Pollution was also responsible for three times as many deaths as AIDS, tuberculosis, and malaria combined



      1. Ichthyosaur Fossil Discovered For First Time In India

    • Scientists in India have discovered a 152 million-year-old fossil of an ichthyosaur - an extinct marine reptile - in the western state of Gujarat.

    • This is the first time an ichthyosaur fossil has been discovered in India.

    • The fossil was found inside rocks from the Mesozoic Era, which ran between 252 and 66 million years ago, in the Kutch desert.

    • Only parts of the skull and tail bones were found to be missing.

    • Often misidentified as "swimming dinosaurs", they first appeared in the early Triassic period (251 million to 199 million years ago)

    • The name means fish-lizard, although the creature has been classified as a reptile since the mid-19th Century

    • An examination of the teeth of the fossil suggests that it was a top-tier predator in its ecosystem.

    • This is a remarkable discovery not only because it is the first Jurassic ichthyosaur record from India, but also it throws light on the evolution and diversity of ichthyosaurs in the Indo-Madagascan region and India's biological connectivity with other continents in the Jurassic.



      1. Four Asian Vulture Species Now On Highest Protection List

    • Several species of vultures, including four that have India on their migratory routes, were awarded the highest protection by the Convention on the Conservation of Migratory Species of Wild Animals.

    • The whale shark, which inhabits the Indian Ocean, got global protection too. However, the proposal to extend additional protection to the chinkara or Indian gazelle was withdrawn.

    • The convention in Manila concluded with approvals for protection of 34 species in submissions made by 24 countries from Asia, Africa, the Americas, Europe and Oceania.

    • The Asian vultures that are set to get collaborative international protection are the red-headed vulture, white-rumped vulture, Indian vulture and slender-billed vulture.

    • Threats: They are faced with threats such as poisoning, hunting, collision with electricity cables and habitat degradation.

    • A subspecies of the black noddy, the yellow bunting and the lesser and great grey shrike are the other avians on the protected list.

    • Lions, chimpanzees, giraffes and leopards were marked out as species that needed additional protection.

    About the Convention on the Conservation of Migratory Species of Wild Animals

    • The Convention on the Conservation of Migratory Species of Wild Animals — more commonly abbreviated to just the Convention on Migratory Species (CMS) or the Bonn Convention — aims to conserve terrestrial, marine and avian migratory species throughout their range. It is an international treaty, concluded under the aegis of the United Nations Environment Programme, concerned with the conservation of wildlife and habitats on a global scale

    • Since the Convention’s entry into force, its membership has grown steadily to include over 120 Parties from Africa, Central and South America, Asia, Europe and Oceania.

    • The Convention was signed in 1979 in Bad Godesberg, a suburb of Bonn (hence the name), and entered into force in 1983. The depositary is the government of the Federal Republic of Germany.

    • The CMS is the only global and UN-based intergovernmental organization established exclusively for the conservation and management of terrestrial, aquatic and avian migratory species throughout their range.
