“…Carbon sequestration is the process of capture and long-term storage of atmospheric carbon dioxide (CO 2 ) (Sedjo and Sohngen, 2012), which is proposed to be the mitigation to global warming. To quantify the amount of CO 2 sequestrated annually by the ecosystem, we estimated net ecosystem productivity (NEP) as a proxy of carbon sequestration, and it can be defined as:…”

Abstract:The significance of biodiversity and ecosystem services are gradually recognized by human as an approach towards sustainability, so it is important to understand relationships and congruence between them to support conservation planning, especially in the hotspot areas with a prominent role in conservation. However, the management of most conservation hotspots mainly focused on biodiversity, and rarely concerned with ecosystem services. With the aim of proposing criteria for conservation strategies that contribute to the optimization of biodiversity and ecosystem services, in this study, a Geographic Information System (GIS)-based approach was designed to estimate and map the biodiversity and ecosystem services in Chongqing Municipality of China. Furthermore, the distributions of hotspot areas for biodiversity and ecosystem services were mapped based on the relationship between cumulative ecosystem services and areas. Finally the statistical analysis was processed focused on specific conservation objectives. The results showed that hotspot areas can conserve the most biodiversity but with the least ecosystem services under the conservation plans target to biodiversity conservation. In contrast, depending on the ecosystem services of interest, hotspot areas can conserve the largest ecosystem services but with the least biodiversity. By integrating biodiversity and ecosystem services into conservation plan, we found that the conservation and regeneration of these small areas, would contribute to a conservation of 44% of the biodiversity hotspot and 14%-42% of the ecosystem services hotspot. Moreover, the current nature reserve selection was not maximize the biodiversity and ecosystem services compared to integration strategy, indicating that hotspot areas conservation and selection is vital for optimization protection of biodiversity and ecosystem services, and has practical significance for natural resources and ecosystem management.

“…For example, the Intergovernmental Panel on Climate Change reports that forests contain about 80% of aboveground and 40% of belowground carbon stock (IPCC 2007). Additionally, it is reported that the amount of carbon stored in dry wood is approximately 50% by weight (Brown 1986;Paladinic et al 2009;Sedjo and Sohngen 2012).…”

Background: Depending on tree and site characteristics crown biomass accounts for a significant portion of the total aboveground biomass in the tree. Crown biomass estimation is useful for different purposes including evaluating the economic feasibility of crown utilization for energy production or forest products, fuel load assessments and fire management strategies, and wildfire modeling. However, crown biomass is difficult to predict because of the variability within and among species and sites. Thus the allometric equations used for predicting crown biomass should be based on data collected with precise and unbiased sampling strategies. In this study, we evaluate the performance different sampling strategies to estimate crown biomass and to evaluate the effect of sample size in estimating crown biomass.

“…Currently, CO 2 concentration has increased at to the alarming rate that creates the need of the environmental amelioration either by decreasing the CO 2 emission in the atmosphere or capturing it into benign products using suitable technology for safe future existence 1 . Carbon sequestration is the process of capturing CO 2 and depositing it for long term where it will not enter into the atmosphere 2 . A great initiation is taken by the Inter-Academy Panel on International Issues (IAP) to reduce the 80% of CO 2 in the atmosphere by 2050.…”

“…Hydration of CO 2 is a rapid reaction; however, it can be accelerated using microbial Carbonic Anhydrase (CA) (EC 4.2.1.1) for subsequent fixation into stable mineral carbonates 6 . Carbonate ion produced by CO 2 sequestration provides a for long-term storage of CO 2 . Moreover, carbonates are thermodynamically stable, environmentally benign and weakly soluble in water, thus minimizing the concerns over the monitoring requirements and long-term fate of CO 2 5 .…”

Background: CO 2 in the environment has been a burning issue and aggravated the threats of global warming. Various strategies are being used to decrease the level of releasing CO 2 . Biosequestration is a one of the available nontoxic, robust and eco-friendly approaches but still less evaluated. This study reports the role of microbial Carbonic Anhydrase (CA) in the formation of calcite by utilizing CO 2 . Methods: The marine Nocardiopsis lucentensis was studied for intracellular microbial CA. Isolate grown optimally at 2.5% CO 2 saturated environment and procedure the calcium carbonate encrust in the presence of CaCl 2 . Results: The enzyme was found to catalyze the reaction in a wide range of pH and temperature with an optimum at 7.0 pH and 25°C. The 50 mM NaCl, KCl and MgCl 2 were found to support the enzyme activity and 50 mM ZnCl 2 increases activity 1.5 fold. CA was able to withstand against sulphanilamide inhibitor and stable over prolonged incubation at 4 and 37°C. Conclusion: Calcite formation was evaluated with and without enzyme using marine water as a source of calcium ions. The result of SEM and EDX indicated the formation of larger flower-shaped particles compare to the small cubic particles formed without enzyme. The results suggest that the robustness of enzyme and suitability in the CO 2 capture reactor.
