THERE'S a maxim in Sanskrit that states peacocks in the forest are happy to see clouds in the sky. It's a pointer to the irrefutable fact of life that one cannot keep away from what is dear to one. Something similar happened to Madeleine Slade, popularly known as Mira Behn, …
ARTHUR Nonomura, an American scientist-turned-farmer, may usher in another green revolution with his discovery that methanol (or methyl alcohol), traditionally thought to be toxic to plants, can stimulate crop growth in hot and dry regions. "I think it's going to save the world," says Andrew Benson of Scripps Institution of …
UNCONTROLLED commercial exploitation is threatening the extinction of about 50 Indian orchid species, including such popular ones as jewel orchids and lady slipper orchids (Current Science, Vol 63, No 12). Though orchids have vast commercial potential, mass multiplication techniques have not been implemented in India. This has resulted in rapid …
THE SPLENDOUS of a tropical rain forest invariably make a profound impression at first sight. "Here I first saw a tropical forest in its sublime grandeur- nothing but the reality can give any idea how wonderful magnificent the scene is..." exulted Charles Darwin, whose theory of evolution significantly shaped modern …
SOME PLANTS produce two types of flowers - starninate (males) and bisexual. Scientists thought the role of starninate flowers was more to attract agents of pollination than to donate pollen. But new research shows that while larger floral displays attract more pollinators, staminate flowers are more effective in the dispersal …
THE FIRST all-India tiger census in 1972 was designed by then senior research officer Saroj Raj Choudhury and his trainees at the Forest Research Institute in Dehra Dun. The method used the hind pugs left by a tiger. No matter how the tiger walks, its hind pugs are usually clear. …
THE NEXT time you pluck a flower, take care: you could hurt it. And, if you are a plant-lover, stop talking to them and try touching them instead. Researchers say seemingly passive plants can feel and react to touch in their own special way (New Scientist, Vol 136 No 1843). …
LITERATURE, they say, is a reflection of the way a society perceives itself. Indians have, from time immemorial, celebrated the interdependence of human beings and nature. The modern era saw them grow apart. The greater the distance between them, the more romantic became the treatment of nature in literature. Indian …
Increasing instances of theft of plant species from Asian countries led delegates at a recent symposium of botanists in New Delhi to stress the need to recognise the importance of taxonomy - the science of classifying organisms. The UNESCO-sponsored meet was organised by Botany 2000-Asia, a network of Asian botanists. …
A RECENT article in The Guardian of London on the role played by the Kew Royal Botanical Gardens in tropical botany has sparked a debate regarding its acquisition of tropical plants. The article pointed out proudly certain plants in Kew Gardens have facilitated the discovery and exploitation of many modern …
FEW OF the Fulani pastoralists in Nigeria have been inside a school and fewer still can read, but they have a very rich knowledge of the value of plants, especially browsable plants which can provide cattle food during the dry season. Researchers at the International Livestock Centre for Africa (ILCA) …
BATS. THE very mention of the word conjures up chilling images of bloodsucking creatures that attack humans insidiously at night. Much maligned in fiction -- who will ever forget the evil Count Dracula? -- these animals have been extensively exterminated over the years. Estimates presented by the Chiropteran (bats belong …
THE "arms race" between plants that produce defence mechanisms to ward of foragers such as deer and animals who attempt to evolve mechanisms to counter these defences, have long intrigued evolutionary biologists. Scientists say the moose (Alces alces), a large herbivorous mammal found in temperate regions, appears to be leading …
IN GLOBAL terms, existing species are estimated at between five and 30 million. Of these, only 1.4 million have been identified, of which 750,000 are insects, 40,000 invertebrates, 250,000 plants and 360,000 pertain to the microbiota. According to some recent estimates, the number of insects alone may be as high …
Leaf fall and reproductive phenology of Avicennia marina assessed during 1982-83 using litter fall collections from twenty-five sites in Australia, Papua New Guinea and New Zealand revealed major trends with latitude. Flowering shifted from NovemberDecember in northern tropical sites, to May-June in southern temperate sites. Periods between flowering and fruiting …
Porpax Lindi. is a small genus found only in the mainland of Asia. It differs from its close relative Eria Lindl. in having the sepals joined into a tube and having a very short pseudobulb which is wider than long. While on an exploration to Silent Valley a curious population …
Deciding between a friend and foe can become challenging. In plants, this dilemma takes a worse dimension because both the friend and foe are the same sometimes. Scientists from the Max Planck Institute of Chemical Ecology in Germany demonstrated how tobacco plants resolve this conflict with a novel change in …
BIOLOGY Yellow pigment clue to evolution Bilirubin, responsible for the yellowish tinge in the skin, eyes and nails of jaundice patients, has for the first time been identified in plants. The pigment was discovered in Strelitzia reginae Aiton, commonly know as the Bird of Paradise plant. It is indigenous to …
WITH the first sunrays in the morning, mouse-ear cress raises its leaves and then lets them droop as the sun sets. Just like honeybees know when to set out to collect nectar. Most organisms have a built-in clock that regulates their biological functions on a roughly 12-hour schedule. Though researchers …
Mother earth is a unique planet unparalleled by its wide variety of flora and fauna. It is distinctive in the sense that it is the only planet where human life knowingly exists. It has gifted human beings with the richness of minerals and natural resources besides the biodiversity, forests and …
