The addition of pyrogenic carbon (C) in the soil is considered a potential strategy to achieve direct C sequestration and potential reduction of non-CO2 greenhouse gas emissions. In this paper, we investigated the long term effects of charcoal addition on C sequestration and soil physico-chemical properties by studying a series of abandoned charcoal hearths in the Eastern Alps of Italy establis...

In arid and semiarid areas, the effects of afforestation on soil organic carbon (SOC) have received considerable attention. In these areas, in fact, soil inorganic carbon (SIC), rather than SOC, is the dominant form of carbon, with a reservoir approximately 2-10 times larger than that of SOC. A subtle fluctuation of SIC pool can strongly alter the regional carbon budget. However, few studies ha...

Calcium ions (Ca(2+)) are indispensable for the physiology of organisms and the molecular regulation of cells. We observed that CGK733, a synthetic chemical substance, induced non-apoptotic cell death and stimulated reversible calcium sequestration by vesicles in pancreatic cancer cells. The endoplasmic reticulum (ER) stress eukaryotic translation initiation factor 2-alpha kinase 3/C/EBP homolo...

The potential for soil carbon (C) sequestration under short-rotation woody crops, like hybrid poplar (Populus spp.), is a significant uncertainty in our understanding of how managed tree plantations might be used to partially offset increasing atmospheric CO2 concentrations. Through development of amulti-compartmentmodel,we reviewed information fromstudies on hybrid poplar and analyzed the pote...

In coastal lagoons, marine benthic macrophyte meadows can be an important element in the resistance to eutrophication of ecosystem, as they function temporary nitrogen sinks, limiting availability this nutrient for opportunistic organisms. The role sinks two dominant species Mediterranean seagrass Cymodocea nodosa and seaweed Caulerpa prolifera, was analysed by different approaches: (i) studyin...

What is carbon (C) sequestration? Carbon sequestration can be defi ned as the capture and secure storage of carbon that would otherwise be emitted to or remain in the atmosphere. The idea is to (1) prevent carbon emissions produced by human activities from reaching the atmosphere by capturing and diverting them to secure storage, or (2) remove carbon from the atmosphere by various means and sto...

Improved agricultural, forestry, and land management practices could be used to increase soil carbon and thereby significantly reduce atmospheric CO2 concentration. Understanding biological and edaphic processes that increase and retain soil carbon can lead to specific manipulations for enhancement of soil C sequestration. These manipulations, however, will only be suitable for adoption if they...
