Biodiversity Regulation 2025
-
New Regulation: The National Biodiversity Authority (NBA) notified the Biological Diversity (Access to biological Resources and Knowledge Associated thereto and Fair and Equitable Sharing of Benefits) Regulation 2025, effective April 29, 2025.
-
Purpose: To manage and ensure fair benefit sharing from the use of biological resources and associated knowledge.
-
Turnover-Based Benefit Sharing: Sets benefit-sharing slabs based on the annual turnover of the resource user, with exemptions for those under Rs 5 crore. Higher turnovers require sharing a percentage of the ex-factory sale price (excluding taxes). Turnover of over 1 crore needs to share a statement.
-
High-Value Resources: Mandates at least 5% benefit sharing from the sale of high-value resources like red sanders and threatened species, potentially exceeding 20% for commercial use.
-
Digital Sequence Information (DSI): Expands the scope to include DSI as part of genetic resources, unlike the previous 2014 guidelines.
-
Researchers & IP: Requires benefit-sharing from researchers and intellectual property applicants, with the NBA retaining 10-15% of collected benefits.
-
Cultivated Medicinal Plants Exempt: Exempts cultivated medicinal plants from benefit sharing, aligning with the Biological Diversity (Amendment) Act 2023. The regulation clarifies benefit-sharing is not required for products with both cultivated/uncultivated plants when identified by the Union Ministry of environment, forest and climate change, in consultation with the Ministry of Ayurveda, Unani, Siddha and Homeopathy or AYUSH.
-
ABS Context: Implements Access and Benefit Sharing (ABS) principles rooted in the Convention on Biological Diversity (CBD) and the Nagoya Protocol.
-
COP-16 Impact: Follows COP-16 of the CBD (2024) which finalized a multilateral mechanism for sharing benefits from DSI use.
Red Admiral
-
First Sighting in India: The European Red Admiral butterfly ( Vanessa atalanta ) has been sighted in India for the first time, specifically in the Dhauladhar mountain range of Himachal Pradesh. This is a significant event for lepidopteran records in India.
-
Confirmation and Location: The sighting was confirmed by an expert on Himalayan butterflies, Lovish Garlani, near Dharamshala at an elevation of 2,500 meters.
-
Biodiversity Significance: The new record increases the documented butterfly species in Himachal Pradesh to 440, highlighting the region’s ecological importance.
-
Distribution and Migration: While common in Europe and North America, this species was previously unrecorded in India. A previous record was from Balochistan in 1929, and it was rediscovered in Pakistanās Lower Chitral region in 2022 after a 93 year gap, and there are no confirmed records from China, Mongolia, or Afghanistan, making this sighting noteworthy.
-
Range Expansion: The sighting potentially indicates an eastward expansion of the species’ range within the Eurasian corridor.
-
Host Plant Availability: The abundance of stinging nettle ( Urtica dioica ), the larval host plant, in the Western Himalayas, along with favorable climate, may have facilitated the butterfly’s migration.
-
Morphological Distinction: The European Red Admiral resembles the Indian Red Admiral ( Vanessa indica ) but is distinguishable by a narrower crimson discal band and a spot on the upper forewing.
-
Conservation Implications: The discovery emphasizes butterfly conservation efforts in the Himalayas and encourages further research on species distribution under changing climate conditions.
-
Uncertainty about Establishment: It is unclear whether this is an isolated migratory event or the start of a breeding population in the region.
Galactic Bone
-
Galactic “Bone” Fracture: Astronomers have identified the cause of a break in the G359.13 galactic filament (“The Snake”), a long, bright structure near the Milky Way’s center.
-
Pulsar Collision: A fast-moving pulsar (a highly magnetized, rotating neutron star) appears to have collided with G359.13.
-
Cause and Effect: The collision distorted the filament’s magnetic field, warping its radio signal and physically fracturing the structure.
-
Evidence: Data from Chandra X-ray Observatory and MeerKAT radio array support the pulsar collision theory. Chandra detected X-ray emissions from the pulsar and potentially accelerated particles (electrons and positrons).
-
High Speeds: The pulsar travels at an estimated 1 to 2 million miles per hour.
-
Significance: This event offers insights into how pulsars interact with galactic magnetic structures and accelerates particles to high energies. Understanding these interactions is crucial for understanding high-energy astrophysical processes.
-
G359.13 Details: The filament stretches 230 light-years, is located 26,000 light-years from Earth, and emits synchrotron radiation due to charged particles spiraling along magnetic field lines.
-
Chandra’s Role: The Chandra X-ray Observatory, a NASA flagship telescope, was instrumental in detecting the pulsar’s X-ray emissions.
