High up the Himalayas, study finds, flowers get smaller and nectar gets concentrated to suit tiny pollinators

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.

Some details of the reproductive journey of a fig wasp, to find a suitable tree and lay eggs while simultaneously pollinate it in the process are known. In a recent study, scientists from the Indian Institute of Science, Bangalore, fill in the gaps in our knowledge about this fascinating journey.

Figs and wasps have a give and take relationship where figs need wasps to pollinate while wasps lay their eggs inside the fig fruits. However, not all fig-wasp relationships are this cordial. There are a set of parasitic wasps that cause more harm to the fig plant than good! A new study has uncovered some of the fascinating abilities of such wasps, especially their ability to sense smell. Ovipositors, specialized organs developed to lay eggs in wasps, have been found to act as a ‘nose’ in sniffing out the best position to lay their eggs, say the researchers. These organs can also detect many chemicals, potentially inspiring new kind of sensors, they claim.
