Forest rehabilitation: benefits for carbon and biodiversity banking
According to researchers, opportunities for carbon sequestration and benefits for biodiversity offered by forest rehabilitation schemes mean they should be given greater value as a tool for carbon offsetting. A new study demonstrates the value of forest rehabilitation for rainforest birds. Globally, 7 million hectares of monoculture forest are planted each year, but 13 million hectares of ...

NASA Partners With Forest Service To Highlight Wildfires, Science
NASA and the U.S. Forest Service signed a Space Act Agreement this week that unites the two agencies in raising awareness about the importance of fire prevention and fire safety. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) This partnership will highlight areas of common interest in wildfires, forest and plant growth research and materials science. The joint effort will be ...

Rise in CO2 could restrict growing days for crops
The positive consequences of climate change may not be so positive. Although plants in the colder regions are expected to thrive as average global temperatures rise, even this benefit could be limited. Some tropical regions could lose up to 200 growing days a year, and more than two billion rural people could see their hopes wither on the vine or in the field. Even in temperate zones, there will ...

Forest Soil Carbon Flux Measurement and Applications
Measuring forest soil carbon flux gives an insight into the health of forest ecosystems and provides feedback on the effects of global warming. This article outlines how soil CO2 efflux is determined and the applications of soil carbon flux research. The Earth’s carbon cycle maintains a steady balance of carbon in the atmosphere that supports plant and animal life. In recent years, ...

Dense planting no obstacle to growth – if the trees are cloned
It isn’t competition for nutrients that make densely planted trees give a worse yield per hectare. The problem is actually genetics. So said World Bioenergy Award winner Professor Laércio Couta at the World Bioenergy conference in Jönköping, Sweden. Laércio Couta won the World Bioenergy Award for his work on eucalyptus cultivation in Brazil. At the conference in ...

Unearthing the Roots of Fungal Symbioses
To understand the bases of mutualistic symbiosis between soil mycorrhizal fungi and plants, an international consortium of researchers conducted the first broad, comparative phylogenomic analysis of mycorrhizal fungi. Scientists describe how the comparative analyses of 18 new fungal genomes allowed them to track the evolution of symbiotic fungi interacting with trees, heath plants and orchids. ...

Salmon provide nutrients to Alaskan streambanks
Adult Pacific salmon spend a great portion of their life in the ocean. But their life began along the banks of freshwater streams. Their life will end there, as well. These important steps in the lifecycle of salmon play a role in the health of streambank ecosystems. David D’Amore and a team of scientists studied how different soils respond to the delivery of “salmon-derived ...

Production of California coastal seaweed communities
The rugged low power D-Opto range of dissolved oxygen instruments have made a tangible difference to the outcomes of a Santa Barbara Coastal Long Term Ecological Research (SBC-LTER) programme. The project’s objective is to determine the relative influence of land- and ocean-based forces on the forests of giant kelp (Macrocystis) off the Santa Barbara coast. These forces include river ...

Amplified Greenhouse Effect Shifts North´s Growing Seasons
Vegetation growth at Earth's northern latitudes increasingly resembles lusher latitudes to the south, according to a NASA-funded study based on a 30-year record of land surface and newly improved satellite data sets. An international team of university and NASA scientists examined the relationship between changes in surface temperature and vegetation growth from 45 degrees north latitude to ...

Preserve, promote, and utilise rich soil life
Healthy soil life can contribute to sustainable agriculture which, in addition to ensuring a good yield, keeps diseases under control and generates carbon and nitrogen retention. That is what Prof. Gerlinde De Deyn, Professor holding a personal chair in Soil Ecology, asserted in her inaugural address at Wageningen University & Research on 18 May. Life underground is richer in species than ...

Cement develops an appetite for C02
Three new studies illuminate the sheer complexity of the aspect of climate science known as the carbon cycle − how carbon dioxide gets into the atmosphere and out again. Sometimes, human agency is at work, but nature takes care of it anyway – as one of the studies reveals in the case of cement, the world’s most widely-used building material. Zhu Liu, postdoctoral scholar at ...

Farming in cities could help feed the world
With traditional food production under threat from climate change, we should switch from agriculture to cell culture, says Lucía Atehortúa. If climate change begins to limit the global production of food and energy crops, it will be necessary to develop a new system of food production. Imagine agriculture in small spaces, using high-tech tools such as photo-bioreactors, generating ...

Met-Ed Continues Vegetation Management Work to Enhance System Reliability
Metropolitan Edison Company (Met-Ed) continues to conduct vegetation management work in communities across its 15 county service area in Pennsylvania as part of its ongoing efforts to help enhance system reliability. To date, Met-Ed tree contractors have trimmed more than 1,100 circuit miles of electric lines as part of its $15 million vegetation management spend for 2013, with an additional ...
