    Species in news: Pygmy Hogs

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Pygmy Hogs

    Mains level: NA

    Few captive-bred pygmy hogs, the world’s rarest and smallest wild pigs, were released in the Manas National Park of western Assam under the Pygmy Hog Conservation Programme (PHCP).

    Pygmy Hogs

    • The pygmy hog (Porcula salvania) is a native to alluvial grasslands in the foothills of the Himalayas at elevations of up to 300 m (980 ft).
    • Today, the only known population lives in Assam, India and possibly southern Bhutan.
    • As the population is estimated at less than 250 mature individuals, it is listed as Endangered on the IUCN Red List.
    • It is designated as a Schedule I species in India under the Wildlife Protection Act, 1972, and offences against them invite heavy penalties.

    About Pygmy Hog Conservation Programme (PHCP)

    • The PHCP is a collaboration among Durrell Wildlife Conservation Trust of UK, Assam Forest Department, Wild Pig Specialist Group of IUCN and Union Environment Ministry.
    • It is currently being implemented by NGOs Aaranyak and EcoSystems India.
    • Six hogs — two males and four females — were captured from the Bansbari range of the Manas National Park in 1996 for starting the breeding programme.
    • The reintroduction programme began in 2008 with the Sonai-Rupai Wildlife Sanctuary (35 hogs), Orang National Park (59) and Barnadi Wildlife Sanctuary (22).

    Species in news: Rare Black Softshell Turtle (Nilssonia nigricans)

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Nilssonia nigricans

    Mains level: Not Much

    A major temple in Assam has signed a MoU with NGOs, the Assam State Zoo-cum-Botanical Garden and the Kamrup district administration for the long-term conservation of the rare freshwater black softshell turtle or the Nilssonia nigricans.

    Two years back, one species from our newscard: Species in news: Hump-backed Mahseer made it into the CSP 2019.  The ‘Puntius Sanctus’ fish in the newscard creates such a vibe yet again.

    A stand-alone species being mentioned in the news for the first time (and that too from Southern India) find their way into the prelims. Make special note here.

     

    Q.Consider the following pairs

    Wildlife Naturally found in
    1. Blue-finned Mahseer Cauvery River
    2. Irrawaddy Dolphin Chambal River
    3. Rusty-spotted Cat Eastern Ghats

    Which of the pairs given correctly matched? (CSP 2019)

    (a) 1 and 2 only

    (b) 2 and 3 only

    (c) 1 and 3 only

    (d) 1, 2 and 3

     

    Nilssonia nigricans

    • Until sightings along the Brahmaputra’s drainage in Assam, the black softshell turtle was thought to be “extinct in the wild”.
    • It was confined only to ponds of temples in northeastern India and Bangladesh.
    • The International Union for Conservation of Nature had in 2021 listed the turtle as “critically endangered”.
    • But it does not enjoy legal protection under the Indian Wildlife (Protection) Act of 1972, although it has traditionally been hunted for its meat and cartilage, traded in regional and international markets.

    Operation Olivia to protect Olive Ridley Turtles

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Olive Ridley Turtles

    Mains level: NA

    Every year, the Indian Coast Guard’s “Operation Olivia”, initiated in the early 1980s, helps protect Olive Ridley turtles as they congregate along the Odisha coast for breeding and nesting from November to December.

    Answer this question from CSP 2012 in the comment box:

    Q.Which one of the following is the national aquatic animal of India?

    (a) Saltwater crocodile

    (b) Olive ridley turtle

    (c) Gangetic dolphin

    (d) Gharial

    Olive Ridley Turtles

    • The Olive Ridley (Lepidochelys olivacea) is listed as vulnerable under the International Union for Conservation of Nature’s Red list.
    • All five species of sea turtles found in India are included in Schedule I of the Indian Wildlife Protection Act, 1972, and in the Appendix I of the CITES, which prohibits trade in turtle products by signatory countries.
    • Odisha has also formulated laws for protecting Olive Ridley turtles, and the Orissa Marine Fisheries Act empowers the Coast Guard as one of its enforcement agencies.
    • Studies have found three main factors that damage Olive Ridley turtles and their eggs — heavy predation of eggs by dogs and wild animals, indiscriminate fishing with trawlers and gill nets, and beach soil erosion.
    • Dense fishing activity along the coasts of Andhra Pradesh, Odisha and West Bengal, especially ocean-going trawlers, mechanized fishing boats, and gill-netters pose a severe threat to turtles.

    Their habitats

    • The Olive Ridley has one of the most extraordinary nesting habits in the natural world, including mass nesting called arribadas.
    • The 480-km-long Odisha coast has three arribada beaches at Gahirmatha, the mouth of the Devi river, and in Rushikulya, where about 1 lakh nests are found annually.
    • They generally return to their natal beach, or where they were born, to lay eggs as adults.
    • Mating occurs in the offshore waters of the breeding grounds and females then come ashore to nest, usually several times during a season.
    • They crawl ashore, dig a flask-shaped nest about 1.5 to 2 foot deep, and lay 100 to 150 eggs in each clutch.
    • Hatchlings emerge from their nests together in about seven to 10 weeks.

    Species in news: Bharitalasuchus Tapani

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Bharitalasuchus Tapani

    Mains level: NA

    In the mid 20th century, researchers from the Indian Statistical Institute, Kolkata, carried out extensive studies on rocks of the Yerrapalli Formation in what is now Telangana, uncovering several fossils of Bharitalasuchus Tapani.

    Bharitalasuchus Tapani

    • This reptile belongs to a genus and species previously unknown to science. It is named Bharitalasuchus tapani considering Telugu etymology.
    • In the Telugu language, Bhari means huge, Tala means head, and Suchus is the name of the Egyptian crocodile-headed deity.
    • The species is named after paleontologist Tapan Roy Chowdhury in honour of his contribution to Indian vertebrate paleontology and especially his extensive work on the Yerrapalli Formation tetrapod fauna.

    Details of the reptile

    • The reptile belonged to a family of extinct reptiles named Erythrosuchidae.
    • A precise identification had not been possible earlier because the family was not known from other examples in India.
    • It was neglected because the fossil specimen was not as complete as those of other erythrosuchids from other countries.
    • The team notes that tapani were robust animals with big heads and large teeth, and these probably predated other smaller reptiles.
    • They were approximately the size of an adult male lion and might have been the largest predators in their ecosystems.

    Back2Basics: Wildlife (Protection) Act, 1972

    • WPA provides for the protection of the country’s wild animals, birds, and plant species, in order to ensure environmental and ecological security.
    • It provides for the protection of a listed species of animals, birds, and plants, and also for the establishment of a network of ecologically important protected areas in the country.
    • It provides for various types of protected areas such as Wildlife Sanctuaries, National Parks, etc.
    • There are six schedules provided in the WPA for the protection of wildlife species which can be concisely summarized as under:
    Schedule I: These species need rigorous protection and therefore, the harshest penalties for violation of the law are for species under this Schedule.
    Schedule II: Animals under this list are accorded high protection. They cannot be hunted except under threat to human life.
    Schedule III & IV: This list is for species that are not endangered. This includes protected species but the penalty for any violation is less compared to the first two schedules.
    Schedule V: This schedule contains animals which can be hunted.
    Schedule VI: This list contains plants that are forbidden from cultivation.

     

  • Native Indian turtles face U.S. slider threat across Northeast

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Red-eared slider

    Mains level: Paper 3- Native Indian turtles face threat from red-eared slider

    About red-eared slider

    • The red-eared slider (Trachemys scripta elegans) derives its name from red stripes around the part where its ears would be and from its ability to slide quickly off any surface into the water.
    • Native to the U.S. and northern Mexico, this turtle is an extremely popular pet due to its small size, easy maintenance, and relatively low cost.

    Reports about threat

    • Between August 2018 and June 2019, a team of herpetologists from NGO Help Earth published the finding in ‘Reptiles & Amphibians’, journal of the U.S.-based International Reptile Conservation Foundation in August 2020.
    • But the alarm was raised experts from Mizoram University’s Department of Zoology published another report in the same journal in April this year.

    How is it a threat?

    • They grow fast and virtually leaves nothing for the native species to eat.
    •  People who keep it as pets become sensitive about turtle conservation but endanger the local ecosystem, probably unknowingly, by releasing them in natural water bodies after they outgrow an aquarium, tank or pool at home.
    • Much like the Burmese python that went to the U.S. as a pet to damage the South Florida Everglades ecosystem, the red-eared slider has already affected States such as Karnataka and Gujarat, where it has been found in 33 natural water bodies.
    • Preventing this invasive species from overtaking the Brahmaputra and other river ecosystems in the Northeast is crucial because the Northeast is home to more than 72% of the turtle and tortoise species in the country, all of them very rare.

    Way forward

    • Although the red-eared slider is traded legally, the time has come for the government to come up with regulations against keeping invasive as pets.
    • There is a need to create awareness among pet traders for maintaining a database of red-eared slider buyers.
    • They can be contacted to hand over the turtles to the repository insulated from any wetland or natural water body.

    Meghalaya records India’s first bat with sticky disks

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Species of bats

    Mains level: Paper 3- Disk-footed bat recorded for first time in India

    About the species

    • A team of scientists from the Zoological Survey of India (ZSI) and a few European natural history museums stumbled upon very specialised small bat with “disk-like pads in the thumb and bright orange colouration”.
    • The flattened skull and sticky pads enabled the bats to roost inside cramped spaces, clinging to smooth surfaces such as bamboo internodes.
    • The disk-footed bat was also found to be genetically very different from all other known bats bearing disk-like pads.

    Significance

    • Meghalaya has yielded India’s first bamboo-dwelling bat with sticky disks, taking the species count of the flying mammal in the country to 130.
    • The disk-footed bat has raised Meghalaya’s bat count to 66, the most for any State in India.
    • It has also helped add a genus and species to the bat fauna of India.
    • There are a couple of other bamboo-dwelling bats in India.
    • But the extent of adaptation for bamboo habitat in this species is not seen in the others.
