• India’s understanding of forest fires has been skewed by colonial-era policy

    Jayashree Ratnam, associate director of the wildlife biology and conservation programme at the National Centre for Biological Science, said that these forests are mesic savannas. “Having worked for a while in African savannas and being very familiar with the idea that mixed tree-grass ecosystems were distinctive from forests, when we returned to India and started visiting various field sites, we were struck by the similarities of these sites with African savannas,” she said.

  • We Need to Save the Bees – but Where Do We Begin?

    A species is identified based on the type specimen that describes the characteristics of that species. So to zero in on the right names to apply to the species, scientists have to extensively study historical specimens and Indian and international museums, he said.

    To this end, Ascher co-organised the second Bangalore Meeting on Asian Bees, on March 1 and 2, along with V.V. Belavadi, Hemalatha Somanathan and Axel Brockmann.

  • Luckily, the rice lost it!

    Today, rice is the most widely consumed staple food in the world, feeding more than half of the world’s population. We have nothing but a tiny piece of RNA, or ribonucleic acid, to thank, for the mouthfuls of rice we eat!

  • When forests are not forests at all, can fire be used to better manage them?

    Jayashree Ratnam, associate director of the wildlife biology and conservation programme at the National Centre for Biological Science, said that these forests are mesic savannas. “Having worked for a while in African savannas and being very familiar with the idea that mixed tree-grass ecosystems were distinctive from forests, when we returned to India and started visiting various field sites, we were struck by the similarities of these sites with African savannas,” she said.

  • Fires are a crucial component of some forest systems, says group of scientists

    Six scientists who study fire-prone forest systems across India have written an open letter on the importance of “fighting fire with fire.” The letter, signed by Dr. Abi Tamim Vanak, Dr. Ankila Hiremath and Dr. Nitin Rai of the Ashoka Trust for Research in Ecology and the Environment (ATREE); Dr. Raman Sukumar of the Indian Institute of Science (IISc); Dr. Jayashree Ratnam of the National Centre for Biological Sciences’ (NCBS); and Tarsh Thekaekara of The Shola Trust, says that “there is an urgent need for a more nuanced view of forest fires.”

  • The identity crisis of the Indian savannas

    In a study, published in the journal Frontiers in Ecology and Evolution, researchers from the National Centre for Biological Sciences, Bengaluru, have shown that grass-fuelled fires and seasonal drought, which are the characteristics of savannas, are also observed in the dry deciduous “forests” in India. These findings add to a growing body of evidence that these systems are, in fact, savannas.

  • Scientists call for rethink of India's British-era forest fire policies

    The forest fire that started at the national park, 220 km from Bengaluru, on February 21 was one of the worst the 87,400-hectare reserve has seen in recent years.

  • Why are fires frequent at the Bandipur reserve?

    Jayashree Ratnam from the National Conservation for Biological Sciences and fellow authors have noted in a recent study that the trees in this landscape were closer to those in a savanna than in rainforests 100 km away. Trees have dramatically thicker barks, implying that they had evolved to be fire-resistant.

    “When fires are relatively frequent, adult tree mortality in these systems is very low. Many saplings sprout shortly after the fire from underground reserves, and the system returns to its original state in a few years,” she told The Hindu.
