Environment & Biodiversity Current Affairs MCQs

Notes:
Following the arrest of a passenger at Kempegowda International Airport (Bengaluru) for smuggling two red-shanked douc monkeys, attention has been drawn to the illegal wildlife trade involving critically endangered primates. The red-shanked douc (Pygathrix nemaeus) is an Old World monkey often described as the “Queen of primates” due to its striking appearance. The species is mainly distributed across Southeast Asia, particularly Vietnam, southern Laos, and Cambodia. The IUCN Red List classifies the red-shanked douc as Critically Endangered, indicating an extremely high risk of extinction in the wild.

Notes:
Tamil Nadu launched a conservation initiative to protect the smooth-coated otter (Lutrogale perspicillata) in the Cauvery River delta due to habitat loss and rising human–wildlife conflict. The programme will estimate population, map habitats, study threats like pollution, dams and pesticides, and restore habitats through reeds planting and fish ladders. Otters live in bevvies of 4–12, communicate with whistles and chirps, and control freshwater ecosystems by feeding on fish. Their numbers fell due to dams, contaminated water, plastic pollution, and loss of prey. It is listed as Vulnerable by the International Union for Conservation of Nature (IUCN) and protected under Schedule I of Wildlife Protection Act, 1972.

Notes:
Researchers from the Nature Conservation Foundation (NCF) have shown that local ecological knowledge of the Adi community can improve efforts to track the critically endangered Chinese pangolin. Chinese pangolin (Manis pentadactyla) is a small, nocturnal mammal fully covered in protective keratin scales. It inhabits subtropical, tropical, and deciduous forests and is distributed across southern China, Taiwan, Hong Kong, Hainan, parts of Southeast Asia including Myanmar, Laos, Thailand, and Vietnam, as well as northern India, Nepal, and Bhutan. The species has been listed as Critically Endangered on the IUCN Red List.

Notes:
The rare Sirkeer Malkoha has been recorded for the first time in Uttarkashi district of Uttarakhand. It is usually found in the plains of Uttarakhand, making this sighting significant. Sirkeer Malkoha, also called sirkeer cuckoo, is a unique type of cuckoo bird. It is found across the sub-Himalayan Indian subcontinent, Bangladesh, Sri Lanka, and parts of Pakistan and Rajasthan. It lives in scrublands, thin forests, and hilly areas. The International Union for Conservation of Nature Red List classifies it as Least Concern.

Notes:
Seven rare galaxy frogs (Melanobatrachus indicus) in Kerala’s Western Ghats have disappeared and are presumed dead after disturbance by wildlife photographers. Photographers overturned logs, trampled vegetation, handled frogs barehanded, and used strong camera flashes. They are endemic to the southern Western Ghats mountain range in India, specifically found in small patches of wet evergreen forests in Kerala and Tamil Nadu. The species is listed as Vulnerable by the International Union for Conservation of Nature (IUCN).

Notes:
The first phase of the All-India Tiger Estimation 2026 (AITE-26) has started in the Thanthai Periyar Wildlife Sanctuary. It is located in the Bargur Hills of Erode district in Tamil Nadu. The sanctuary lies between Sathyamangalam Tiger Reserve of Tamil Nadu and Male Mahadeshwara and Cauvery Wildlife Sanctuaries of Karnataka. The area is part of the Nilgiris Elephant Reserve.

Notes:
Scientists led by “Frogman of India” S. D. Biju discovered two new frog species from remote mountain regions of Arunachal Pradesh. Soman’s Slender Arm Frog, scientifically named Leptobrachium somani, was discovered at Tiwarigaon and named in honour of environmental journalist E. Somanath. This small frog is about 55 millimetres long, has a greyish-brown body with light-grey markings, and silver-grey to light-blue eyes. It lives in evergreen forests, with males calling near slow or fast-flowing streams. Mechuka Slender Arm Frog, known as Leptobrachium mechuka, is named after Mechuka town where it was first found.

Notes:
The Union Minister for Environment, Forest and Climate Change chaired a meeting of NIRANTAR, the National Institute for Research & Application of Natural Resources to Transform, Adapt and Build Resilience. NIRANTAR is a collaborative platform of institutions under the Ministry of Environment, Forest and Climate Change (MoEFCC) aimed at strengthening coordination and cooperation. The platform is organised into four verticals that focus on research, assessment, and utilisation of natural resources, with special emphasis on bioresources. NIRANTAR seeks to promote sustainable use of bioresources to support development while ensuring ecological balance.

Notes:
The Miyawaki method is increasingly used in cities where green cover has declined over decades, and it is often seen in recent urban greening drives. It is an afforestation technique developed in the 1970s by Japanese botanist Akira Miyawaki. Trees and shrubs are planted very close together, also called the pot plantation method. Only native species are planted, creating a resilient and balanced ecosystem. Forests grow nearly 10 times faster and become very dense with high biodiversity. Recent municipal projects have used this method to convert polluted and barren urban land into green spaces, reducing pollution, improving soil, and enhancing ecological balance.

Notes:
A recent survey across the Ganga River basin recorded 3,037 gharials in 13 rivers despite serious survival threats. Gharial is a freshwater crocodile belonging to the Crocodylia order and Crocodylidae family. Its scientific name is Gavialis gangeticus and it mainly feeds on fish. Earlier, its range extended across Bangladesh, Bhutan, India, Myanmar, Nepal, and Pakistan. Today, major populations survive in the Chambal, Girwa, and Rapti–Naryani rivers. In India, gharial reserves are located in Uttar Pradesh, Madhya Pradesh, and Rajasthan. As per the International Union for Conservation of Nature (IUCN) Red List, it is critically endangered.
