A collaborative study from the Indian Institute of Science, Bangalore, and other institutes, found that agamid lizards display rapid colour change in different contexts, including thermoregulation, communication, and stress. The massive range of colours in these species opens up new questions on the whys, hows, and whens of this colour change.
A recent study led by Anindita Bhadra at the Indian Institute of Science Education and Research, Kolkata, has analysed the foraging behaviour of stray dogs scavenging in groups in West Bengal. The findings have implications for understanding dog behaviour in stressful environments and potential conflicts between dogs and humans or among dogs in group settings.
Protecting India's rich biodiversity has usually taken the form of designating protected areas like national parks and wildlife sanctuaries. Several of these are contiguous with larger landscapes that lack such protection status and that form continuous habitat ranges for many animals. In a recent study, a team of Indian researchers have highlighted the need for more focused conservation strategies in the Bhagirathi basin in Uttarakhand.
When selecting sites for laying eggs, female Aedes mosquitoes avoid water puddles that lack predators and choose ones with a few predators instead. Researchers from the Indian Institute of Science (IISc), Bengaluru, and the Nature Conservation Foundation (NCF), Mysore, explain this puzzling behaviour of Aedes mosquitoes.
In an on-going effort to convert certain inland waterways into national waterways, many rivers are undergoing commercialization, including the Ganges. This has critically affected the habitat and survival of one of its flagship species, the endangered Ganges river dolphin. A recent study provides empirical scientific data to understand how anthropogenic interventions are impacting the already dwindling population of aquatic animals.
The Hemidactylus geckos have evolved into several distinct species in the Indian peninsula, some of which often show up as uninvited guests in our houses. Researchers at the Center for Ecological Sciences, Indian Institute of Science (CES-IISc) have shown that differences in morphology among species of ground-dwelling geckos can indicate changes in the past climate of peninsular India.
Researchers from the Centre for Climate Studies, Sathyabama Institute of Science and Technology, Chennai, have discovered that the accumulation of chromium (a heavy metal) and low salinity might have caused mass death of fish in the Adyar estuary in Tamil Nadu in 2017.
