How accurate are India’s tiger numbers?

According to the National Tiger Estimation survey, the number of tigers has surged to 2967, indicating a doubling of tiger numbers since the first survey conducted in 2006 under a revised monitoring methodology. Although this change may sound exciting to the layperson, some scientists have flagged concerns about accepting these claimed changes in tiger numbers. In a recent study, published in the journal Conservation Science and Practice, researchers from India and Norway refer to important mathematical, statistical and ecological principles and highlight how India’s tiger survey results deviate from these principles.

Toxic elements, released since the Industrial Revolution, find their way to the Himalayas

In the 18th and 19th century, Britain was abuzz with cranking steam engines, rattling power looms, and clattering machines. Amidst this daily ding, the world was witnessing a defining movement in human history—the Industrial Revolution—that soon spread to the rest of Western Europe. Powered by coal, the production of most things transitioned from hand to machine, spurring a rise in population and air pollution. For the next two centuries, London became infamous for its soot and smog, which turned fatal for about 12,000 people. Now, a new study has shown that this mal air has left its trace in the lofty Himalayan glaciers, thousands of kilometres away from Europe.

Dams are dividing the world’s fish habitats, and India is one of the most affected

In a new study, an international team of researchers have found that large dams have heavily fragmented fish population across the world. Published in the Proceedings of the National Academy of Sciences, the study assessed about ten thousand species of fish worldwide affected by around 40,000 existing dams and 3,700 upcoming dams worldwide. The findings reveal that fish habitats are most disconnected in the United States, Europe, South Africa, India, and China. The proposed dams are poised to further worsen fish habitat connectivity in tropical watersheds like the Amazon, Congo, Mekong and Salween.

Mystery river snail reveals dispersal events into Indian subregion

Mud snails, also known as mystery snails, live in freshwater and belong to a snail family called Viviparidae. They are found throughout the world except in South America and Antarctica. Such globally distributed species incite interesting questions about their dispersal across different continents. In a recent study, researchers in Bengaluru from the Ashoka Trust for Research in Ecology and the Environment (ATREE) and the Indian Institute of Science (IISc), investigated manifestation of these mystery snails in India.

Friendly neighbours? Study shows crop yield increases when biodiverse environments surround farms

As winter sets in over Punjab, one can hear the humdrum of hundreds of machines harvesting rice across lakhs of hectares of paddy fields. In Maharashtra, villages in Vidarbha lug their snowy cotton harvest to the market. Years ago, these landscapes were a sprawling array of forests, grasslands, wetlands and multiple crops cultivated on a shifting basis.
