forest ecosystems and their optimal management can play effective roles in mitigating the carbon emission as well as absorbing the atmospheric carbon. the present research was carried out to determine the effects of 21 year old stands of cryptomeria japonica, cupressus sempervirens, pinus taeda, acer pseudo-platanu and mixed plantation and natural forest stands on sequestration of carbon in the...

We review progress in understanding sequestration by herbivorous insects, the use of plant chemical defenses for their own defense. We incorporate sequestration into the framework of plant-insect coevolution by integrating three hierarchical issues: (1) the relationship between dietary specialization and sequestration of plant defenses, (2) the physiological mechanisms involved in sequestration...

ongoing climate change has been a major global challenge since the 1880s. sequestration of carbon(c) in rangelands ecosystems could provide a net carbon sink to offset increases in atmospheric c in global scale. this research is aimed at estimating the above-ground biomass carbon sequestration potential in iran. for this purpose, total rangelands area and productivity data were extracted from t...

arid and semi-arid lands cover around one-third of the world's terrestrial expanse and their widespread plantdistributions provide these areas with a high potential for sequestering carbon. vegetation management for developingshrub or tree species in arid and semi-arid regions is one inexpensive and multi-purpose approach for decreasing co2.this study assessed the potential of carbon sequestrat...

Direct injection of CO2 into the ocean is a potentially effective carbon sequestration strategy. Therefore, we want to understand the effectiveness of oceanic injection and develop the appropriate analytic framework to allow us to compare the effectiveness of this strategy with other carbon management options. Here, after a brief review of direct oceanic injection, we estimate the effectiveness...

Sequestration of porcine muscarinic acetylcholine receptor m2 subtypes (m2 receptors) expressed in COS-7 cells is facilitated by coexpression of G protein-coupled receptor kinases 2 (GRK2). We examined the effect of coexpression of GRK2, GRK4 delta, GRK5 and GRK6 on sequestration of human m1-m5 receptors expressed in COS-7 cells, which was assessed as loss of [3H]N-methylscopolamine binding act...

The pathogenesis of coma in severe Plasmodium falciparum malaria remains poorly understood. Obstruction of the brain microvasculature because of sequestration of parasitized red blood cells (pRBCs) represents one mechanism that could contribute to coma in cerebral malaria. Quantitative postmortem microscopy of brain sections from Vietnamese adults dying of malaria confirmed that sequestration i...
