Although cover crops are typically terminated 2–4 weeks prior to cash crop planting, there may be situations where late-burndown or planting into a living (planting green) necessary even beneficial. This experiment investigated the effect of termination date on corn (Zea mays) yield and presence beneficial insects. Three different dates were tested: 4 (brown), 7 14 days (green-brown), at (green...

nowadays green house gases such as carbon have the most effect on global climate changes that can be decreased by plant and soil carbon sequestration of rangelands. livestock grazing has high potential to decrease or increase carbon storage. so this research investigated the effects of enclosure on plant carbon storage in rangeland of enclosure (shah tappeh-chah mahmood) and no enclosure (chiro...

Global urban expansion has created incentives to convert green spaces to urban/built-up area. Therefore, understanding the distribution and dynamics of the land-cover changes in cities is essential for better understanding of the cities’ fundamental characteristics and processes, and of the impact of changing land-cover on potential carbon storage. We present a grid square approach using multi-...

Analyzing spatiotemporal variation of tree cover could enhance understanding of the environment and promote a sustainable resource use of ecosystems. This study investigated the variation in tree cover in the Loess Plateau after an ecological restoration effort called the ‘Grain for Green Project’ (GGP). The results show that the proportion of tree covered area in the Loess Plateau changed from...

The aim of the present study was to investigate the relationship between green areas and adolescents' body mass index (BMI). This is based on the notion that nature environment is known to have beneficial effects on human health, and that some of the explanation for this is that green areas are especially motivating or suitable as arenas for physical activity. We included 10,527 participants fr...

www.sciencemag.org SCIENCE VOL 326 30 OCTOBER 2009 633 COVER Crystal structures of the 70S ribosome from the bacterium Thermus thermophilus in complex with translation elongation factors Tu (EF-Tu) and G (EF-G). During protein synthesis, EF-Tu (in periwinkle blue, center) delivers an aminoacyl transfer RNA (green) to the ribosome for each amino acid indicated by the messenger RNA. As the polype...

Various metrics are employed in pharmaceutical sector to define a system-wide, cycle-based perspective so as to deduce an accurate measure of ‘greenness’ of chemical processes and products. Green metrics cover areas of resources, materials, processing, cleaning, life cycle assessment and renewability. This review describes commonly used metrics to measure greenness of chemical reactions and pro...

About the cover: Colocalization of P2X4 using Anti-P2X4 antibody (#APR-002) (red) and P2X3 (green) subunits in the distal population of GPN neurons in situ by confocal immunofluorescence. Special Acknowledgement to Professor Colin A. Nurse from the Department of Biology McMaster University, Ontario Canada for allowing Alomone Labs to use part of a published figure as this Modulator's cover page...

Accurate estimates of forest canopy are essential for the characterization of forest ecosystems. Remotelysensed techniques provide a unique way to obtain estimates over spatially extensive areas, but their application is limited by the spectral and temporal resolution available from these systems, which is often not suited to meet regional or local objectives. The use of unmanned aerial vehicle...

Background/Purpose: In the context of the European Biodiversity policy, the Green Infrastructure Strategy is one supporting tool to mitigate fragmentation, inter-alia to increase the spatial and functional connectivity between protected and unprotected areas. The Joint Research Centre has developed an integrated model to provide a macro-scale set of indices to evaluate the connectivity of the N...
