Order of the National Green Tribunal in the matter of R.D. Singh Bandral Vs Union of India & Others dated 17/04/2023. The matter related to protecting the flora and fauna of the Kailash Kund-Seoz Dhar region by declaring the same as protected area and not to allow construction of the …
ADDIS ABABA, Ethiopia – When Ethiopia’s first botanic garden was established six years ago, few Ethiopians knew of country’s flora heritage. But with agro-ecological zones ranging from 125 meters below sea level to about 5,000 meters above sea level, the country boasts one of the richest flora heritages in Africa …
BENGALURU: The Central government on May 26 has sent a letter to the state government seeking clarifications on the decision to reject the Dr K Kasturirangan report on the protection of western ghats in Karnataka. In a written reply to Ivan D'Souza (Congress) at the legislative council, forest and environment …
Both plants and animals make decisions in response to the environment to maximize their fitness. Plants use dormancy in seeds to move through time and space, and timing of the transition to germination is influenced by external cues, including temperature. Here, we report the presence of a decision-making center within …
Virulent pests and diseases that are ravaging Africa’s forests with profound intensity pose new threats to their survival, experts said at a forum in Entebbe, Uganda on Wednesday. The experts drawn from the fields of botany and entomology noted that tree pests and diseases are spreading fast in many parts …
From new parsnips and herbs to begonias and roses, the world’s plant hunters discovered more than 1,700 new species last year, offering the prospect of better crops and new colours and scents in the garden. The State of the World’s Plants report, led by scientists at the Royal Botanical Garden …
A study using data stretching back several decades has produced the first empirical evidence that increasingly hot, dry summers driven by climate change are having a negative effect on the Cape's unique fynbos. The findings also raise questions about the effect this climate change impact could have on the Western …
The spread of pests and pathogens that damage plant life could cost global agriculture $540 billion a year, according to this report released by the Royal Botanic Gardens in London. An increase in international trade and travel had left flora facing rising threats from invasive pests and pathogens, and called …
More than 500 scientists have converged in Nairobi to explore ways and means of protecting endangered plants. Sports, Culture and Arts CS Hassan Wario said plant science applications have helped address contemporary enviromental challenges. He was speaking during the Association for the Taxonomic Study of the Flora of Tropical Africa …
Increasing emission rate of carbon dioxide (CO2) and other greenhouse gases is the major driver of global temperature increase. Soil microbial respiration is accelerating the release of CO2 in the environment, but the mechanistic understanding of this process is still at its nascent stage. In this note, we discuss the …
Dried plant products of North west Rajasthan which are cooked as a vegetable known as Trikuta-seeds of Acacia Senegal (L.) Willd., unripe fruits of Capparis deciduas (Forssk.) Edgew. and unripe pods of Prosopis cineraria (L.) Druce were tested against seven clinical isolates including one Gram positive and six Gram negative …
Some of the UK’s rarest plants are at risk of extinction unless action is taken to look after the road verges that have become their final refuge, a charity has warned. Species such as fen ragwort and wood calamint are now only found on road verges, with fen ragwort hanging …
The Himalayan nettle (Note 1) is a fiber yielding non-timber forest product that has cultural, economic and medicinal values to many ethnic communities residing in the hill and mountain areas of Nepal and India. If the nettle value chain can be strengthened at each node of the chain, then it …
Growth in terrestrial gross primary production (GPP)—the amount of carbon dioxide that is ‘fixed’ into organic material through the photosynthesis of land plants—may provide a negative feedback for climate change. It remains uncertain, however, to what extent biogeochemical processes can suppress global GPP growth. As a consequence, modelling estimates of …
Pollinator-driven diversification is thought to be a major source of floral variation in plants. Our knowledge of this process is, however, limited to indirect assessments of evolutionary changes. Here, we employ experimental evolution with fast cycling Brassica rapa plants to demonstrate adaptive evolution driven by different pollinators. Our study shows …
Bhadra backwaters attract wild animals as other water bodies dry faster With the Malnad region reeling under its worst drought situation, the district where five rivers take birth is experiencing water crisis. The backwaters of the Bhadra reservoir, situated on the periphery of the Bhadra reserve forest, are slowly drying …
To explain diversity in forests, niche theory must show how multiple plant species coexist while competing for the same resources. Although successional processes are widespread in forests, theoretical work has suggested that differentiation in successional strategy allows only a few species stably to coexist, including only a single shade tolerant. …
Lignin, one of the most abundant biopolymers on Earth, derives from the plant phenolic metabolism. It appeared upon terrestrialization and is thought critical for plant colonization of land. Early diverging land plants do not form lignin, but already have elements of its biosynthetic machinery. Here we delete in a moss …
Plants with rising atmospheric carbon dioxide (CO2) level in the environment may change their nutrient demands to sustain growth. The mechanisms concerning iron dynamics in plants under the interactive effect of salinity and elevated CO2 are poorly understood. This study examines the effects of long-term as well as short-term growth …
AHMEDABAD: The controversial proposals of the Gujarat forest department which greatly reduce the eco-sensitive buffer zones around its sanctuaries -including Nalsarovar, Porbandar Bird Sanctuary, Gaga Great Indian Bustard Sanctuary among others-are ready. For five sanctuaries, muchsmaller eco-friendly zones have already been approved, at a meeting held on October 20. The …
The health of honey bee colonies cannot be understood apart from the landscapes in which they live. Urban and agricultural developments are two of the most dramatic and widespread forms of human land use, but their respective effects on honey bees remain poorly understood. Here, we evaluate the relative attractiveness …
