TAU researchers use organic polymer to protect scorched soil from erosion Wildfires cause tragic losses to life, property, and the environment. But even after the fire rages, the damage is far from done. Without vegetation, bare, burnt soil lies vulnerable to erosion, which can impede efforts towards natural forest regeneration. Now Assaf Inbar, a graduate student at Tel Aviv University's Porter School of Environmental Studies, together with his supervisors Prof. Marcelo Sternberg of...

The Environmental Sciences Network Life-Sciences.net features the latest scientific publications in this discipline. The most recently featured articles deal with the effects of temperature and precipitation on vegetation in the upper catchments of the Yellow River in China, and spatial data management priorities for assessment of Europeâs coasts and seas. (PRWEB) November 23, 2011 The Environmental Sciences category of the Life-Sciences Magazine covers the external physical...

Study used over 300,000 mammal records from US to assess importance of climate, land cover on species presence at various scales Analysis of a massive set of mammal data accessed through the GBIF Data Portal has helped quantify the influence of various environmental factors on which species are present in a particular area. A team of Israeli scientists based at the Technion Institute, Haifa, used all available mammal occurrence records with detailed coordinates in the ℠lower...

Primary succession on the slopes University of Guam ecologist Thomas Marler recently mobilized efforts to characterize the vegetation that has recovered following the eruption of Mount Pinatubo, Philippines. "My interest was sparked by the paradox that this volcano's cataclysmic 1991 eruption was so powerful it changed global climate, yet after a full 15 years the biology of the recovering ecosystem had not been studied," said Marler. The void of research motivated the Guam ecologist to spend...

"Macrosystems biology" funding supports predictive understanding of large-scale biological responses to climate, land-use change Biological sciences writ large, it might be called. To better detect, understand and predict the effects of climate and land-use change on organisms and ecosystems at regional to continental scales, the National Science Foundation (NSF) has awarded 14 grants in "macrosystems biology." How will the biosphere respond to natural and human-induced changes...

The world's largest database on plants' functional properties, or traits, has been pub-lished. Scientists compiled three million traits for 69,000 out of the world's ~300,000 plant species. The achievement rests on a worldwide collaboration of scientists from 106 re-search institutions. The initiative, known as TRY, is hosted at the Max Planck Institute for Biogeochemistry in Jena (Germany). Jointly coordinated with the University of Leipzig (Germany), IMBIV-CONICET (Argentina), Macquarie...

Process uses commercial camera, free software to produce accurate, inexpensive results The productivity and health of horticultural crops depends on the ability of the plant cover to intercept light energy. This ability is a function of the amount of leaf area, the architecture of the vegetation cover, and plants' ability to convert light energy. One estimate of a crop's ability to capture light energy is the leaf area index (LAI). Introduced in 1947, the concept of the LAI was defined as the...

Heavy and prolonged snowfall can bring about unexpected conditions that encourage fungal growth, leading to the death of plants in the Arctic, according to experts. A new international study confirms that whilst snow has an insulating effect which helps plants to grow bigger, heavy and prolonged snow can, in certain circumstances, also encourage the rapid and extensive growth of killer fungal strains. The research results, published in the journal Nature Climate Change, show for the first...

A PhD student at the University of Leeds has developed a fast, accurate and inexpensive method of creating detailed vegetation community maps over very large areas, by coupling aerial photographs with data from maps. Working in partnership with the Yorkshire Dales National Park Authority, Ute Bradter from Leeds' Faculty of Biological Sciences, has collated existing data (such as soil type, altitude, slope and aspect) and using a sophisticated statistical model, predicted the distribution of...

First hectare-scale maps of canopy height, aboveground biomass and associated carbon stock for the forests and woodlands of the conterminous United States The Woods Hole Research Center has released the first hectare-scale maps of canopy height, aboveground biomass, and associated carbon stock for the forests and woodlands of the conterminous United States. The multi-year project, referred to as the National Biomass and Carbon Dataset (NBCD), produced maps of these key forest attributes at an...
