The flowers in the Himalaya, a favourite among mountaineers, may have borrowed a lesson or two from the adrenaline-high visitors. As they climb higher, mountaineers carry only essential things, shedding any extra baggage. Likewise, the flowers here shrink in their size and hold less nectar to suit their tiny pollinators, finds a recent study on Rhododendrons, a type of woody flowering plants. The study was conducted by researchers at the Ashoka Trust for Research in Ecology and Environment, Bengaluru and is published in the journal Alpine Botany. 

The blackbuck is an antelope species native to the Indian subcontinent. Although the term 'antelope' is loosely used to refer to many ruminating ungulates, the blackbuck is the only animal that belongs to the genus named Antilope. True antelopes belong to one of the four genera—Gazella, Nanger, Eudorcas and Antilope. Scientists are still debating the evolutionary relationships between these members. In a recent study, researchers at the Indian Institute of Science, Bengaluru, have traced the evolutionary relationships of the blackbuck (Antilope cervicapra) using phylogenetics. The study was published in the journal Molecular Phylogenetics and Evolution.

A specimen of a cuckoo bee  lay in a museum in Austria for decades before Dr Petr Bugosch took a look at it and described it as a new species, Epeolus ladakhensis. 

Researchers study how fig tree distribution influences fig wasps’ dispersal evolution.

The city of Delhi has been consistently ranked as one of the world's most polluted cities. As the monsoon ends, haze sets in, with Deepawali around the corner, bringing the entire city to a standstill with low visibility. Besides vehicular emissions, smoke from diesel generators and construction dust, a significant contributor to this problem is the practice of crop residue burning by farmers in Punjab and Haryana. A recent study, published in the journal Nature Sustainability, suggests that groundwater conservation policies, adopted by Punjab and Haryana, have changed the patterns of rice production. These policies, the researchers argue, have led to the concentration of crop residue burning into a narrower period, later in the season.

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.

Antimicrobials, a class of drugs used in humans and animals to treat diseases caused by bacteria, fungi, and parasites serve as a proxy for good hygiene and make up for the poor husbandry practices in animal farms in low and middle-income countries around the world. However, this dereliction comes with a considerable cost wherein, the overuse of these drugs has led to these microbes developing resistance against the very same drugs used to kill them.  Antimicrobial resistance (AMR) in humans is linked to several animals, especially those that are raised for food. Despite this knowledge, it has received little attention in the world of animal science. A new study, published in the journal Science, has mapped the global trends of antimicrobial resistance in farm animals, with particular focus on developing countries, including India. 

The Indian krait is undoubtedly the deadliest of all venomous snakes in the country, and possesses the most lethal concoction of poisons. In a study, a multi-institute research team, led by the Translational Health Science and Technology Institute (THSTI), Faridabad, have designed a synthetic antivenom with a nucleic acid aptamer which can diagnose Indian krait bites accurately and effectively.

It’s getting tougher for the Royle’s pikas to survive in the Himalayas. But, these tiny, herbivores wouldn't move as they are particular about where they live. Restricted to rocky, mountainous terrains, they are now facing the wrath of rising temperatures and fluctuating environments. What would become of them in a few more decades? Can these fussy relatives of the rabbit find new homes and thrive? A new study by researchers from the Indian Institute of Science, Bengaluru and the Wildlife Institute of India, Dehradun tries to find out what the future holds for them, and that the findings are not good news.
