Environment & Biodiversity Current Affairs MCQs

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:
A powerful winter storm rapidly intensified into a bomb cyclone named Winter Storm Ezra across the United States of America (USA). More than 58 million people were under winter storm warnings, with blizzards, strong winds, and power outages. A bomb cyclone forms when atmospheric pressure drops sharply within 24 hours, causing extreme weather. Authorities warned against travel as hazardous conditions continue moving eastward.

Notes:
Ladakh’s double-humped Bactrian camels will debut at the 77th Republic Day parade, highlighting their unique heritage. Scientifically known as Camelus bactrianus, they are large even-toed ungulates called Ladakh’s “silent warriors”. They are native to Central Asia, ranging from Afghanistan to China, mainly in the Mongolian steppes and Gobi Desert. In India, small populations survive in the high-altitude cold desert of Nubra Valley, Ladakh. They are mainly herbivores and are listed as Critically Endangered by the International Union for Conservation of Nature (IUCN).

Notes:
Scientists discovered a new species of reed snake in Mizoram and named it Calamaria mizoramensis after the state. It is a non-venomous snake, meaning it does not produce poison harmful to humans. The species is nocturnal, active mainly at night, and semi-fossorial, meaning it partly lives underground. It inhabits humid, forested hill regions at elevations of 670 to 1,295 metres above sea level, even near human settlements. The snake is small, with a dark brown to blackish body, faint stripes, and a yellow underside.

Notes:
Forest staff at Anamalai Tiger Reserve will use the Monitoring System for Tigers: Intensive Protection and Ecological Status (MSTrIPES) app for wildlife census. MSTrIPES is a software-based system for monitoring and protecting tiger habitats. It was launched in 2010 by the National Tiger Conservation Authority (NTCA) with the Wildlife Institute of India. It supports wildlife protection, monitoring, and management of Protected Areas. The system has a central desktop and online analysis tool, and an Android mobile application. The mobile app records field observations and patrol tracks using Global Positioning System (GPS).

Notes:
Scientists have confirmed India’s first case of freshwater pufferfish poisoning, highlighting a new public health concern. Pufferfish belong to the order Tetraodontiformes and are also called toadfish, patkafish, balloonfish, and fugu. They are omnivorous and benthic, meaning they live and feed near the river bottom. In India, they are mainly found in the Western Ghats and river basins like Ganga, Brahmaputra, and Mahanadi. Freshwater pufferfish species in India are often endemic and indicate healthy river ecosystems. According to International Union for Conservation of Nature (IUCN), pufferfish are listed as Vulnerable.

Notes:
Recently, the second rangewide survey of riverine and estuarine dolphins in India was launched from Bijnor, Uttar Pradesh under Project Dolphin. The initiative is led by the Union Ministry of Environment, Forest and Climate Change to strengthen river ecosystem conservation. The survey updates population estimates, assesses habitat conditions, and identifies emerging threats to dolphin species. It is coordinated by the Wildlife Institute of India (WII), Dehradun, with State Forest Departments and partners like WWF India, Aaranyak, and Wildlife Trust of India.

Notes:
Recently, two new safari gates were inaugurated at the Bor Tiger Project in Maharashtra. Bor Tiger Reserve is located in the Wardha district of Maharashtra. It is the smallest tiger reserve in India in terms of area. The reserve covers about 138.12 square kilometres, including the drainage basin of the Bor Dam. It holds strategic importance as it is centrally located among major Bengal tiger habitats.

Notes:
The Ministry of Environment, Forest and Climate Change declared Kumbhalgarh Wildlife Sanctuary in the Aravalli mountain range as an Eco-Sensitive Zone. The move aims to conserve the area’s flora and fauna and support indigenous communities living nearby. Kumbhalgarh Wildlife Sanctuary is located in the Aravalli mountain range, a significant hill system in western India, covering parts of Rajasthan’s Rajsamand, Pali, and Udaipur districts. The 0–1 km area around the sanctuary hosts leopards, striped hyenas, jungle cats, Indian pangolins, blue bulls, chinkaras, and birds like painted francolin.

Notes:
The State Board of Wildlife (SBWL) declared the Striped Tiger Butterfly as the State Butterfly of Chandigarh. The decision was taken in a meeting chaired by Union Territory (UT) Administrator Gulab Chand Kataria. The move aims to promote biodiversity conservation and public awareness in the Union Territory. The Forest and Wildlife Department was directed to run awareness campaigns at public places. The Sukhomajri Project and Sukhna Lake watershed were praised for soil, moisture, and silt management.
