Download Spatial Patterns and Mechanisms for Terrestrial Ecosystem Carbon Fluxes in the Northern Hemisphere Book in PDF, ePub and Kindle
This book systematically illustrates the underlying mechanisms of spatial variation in ecosystem carbon fluxes. It presents the regulation of climate pattern, together with its impacts on ecosystem traits, which yields new insights into the terrestrial carbon cycle and offers a theoretic basis for large-scale carbon pattern assessment. By means of integrated analysis, the clear spatial pattern of carbon fluxes (including gross primary production, ecosystem respiration and net ecosystem production) along latitudes is clarified, from regions to the entire Northern Hemisphere. Temperature and precipitation patterns play a vital role in carbon spatial pattern formation, which strongly supports the application of the climate-driven theory to the Northern Hemisphere. With regard to the spatial pattern, the book demonstrates the covariation between production and respiration, offering new information to promote current respiration model development. Moreover, it reveals the high carbon uptake of subtropical forests across the East Asian monsoon region, which challenges the view that only mid- to high-latitude terrestrial ecosystems are principal carbon sink regions, and improves our understanding of carbon budgets and distribution.

Download Water and Carbon Dynamics, Ecosystem Stability of Forest and Grassland in Response to Climate Change Book in PDF, ePub and Kindle
Forest and grassland ecosystems are the most important carbon sinks in terrestrial ecosystems. They can maintain or enhance carbon stocks and sinks in biomass, and play vital roles in mitigating climate change. China is taking action to achieve its carbon peak and carbon-neutral targets. Climate change, particularly the increase in the frequency, severity, and extent of drought, will affect the stability of the forest and grassland. How forests and grassland mitigate and adapt to climate change is still a challenge. Exploring the response of the forest and grassland to extreme climate events contributes to improving vegetation quality and enhancing the ability to respond to climate change.

Download Direct and Indirect Human Contributions to Terrestrial Carbon Fluxes Book in PDF, ePub and Kindle
Human-induced climate change is an important environmental issue worldwide, as scientific studies increasingly demonstrate that human activities are changing the Earth's climate. Even if dramatic reductions in emissions were made today, some human-induced changes are likely to persist beyond the 21st century. The Kyoto Protocol calls for emissions reporting that separates out management-induced changes in greenhouse gases from those changes caused by indirect human effects (e.g., carbon dioxide fertilization, nitrogen deposition, or precipitation changes), natural effects, and past practices on forested agricultural lands. This book summarizes a September 2003 workshop where leaders from academia, government and industry came together to discuss the current state of scientific understanding on quantifying direct human-induced change in terrestrial carbon stocks and related changes in greenhouse gas emissions and distinguishing these changes from those caused by indirect and natural effects.

Download Phenology of Ecosystem Processes Book in PDF, ePub and Kindle
Terrestrial carbon balance is uncertain at the regional and global scale. A significant source of variability in mid-latitude ecosystems is related to the timing and duration of phenological phases. Spring phenology, in particular, has disproportionate effects on the annual carbon balance. However, the traditional phenological indices that are based on leaf-out and flowering times of select indicator species are not universally amenable for predicting the temporal dynamics of ecosystem carbon and water exchange. Phenology of Ecosystem Processes evaluates current applications of traditional phenology in carbon and H2O cycle research, as well as the potential to identify phenological signals in ecosystem processes themselves. The book summarizes recent progress in the understanding of the seasonal dynamics of ecosystem carbon and H2O fluxes, the novel use of various methods (stable isotopes, time-series, forward and inverse modeling), and the implications for remote sensing and global carbon cycle modeling. Each chapter includes a literature review, in order to present the state-of-the-science in the field and enhance the book’s usability as an educational aid, as well as a case study to exemplify the use and applicability of various methods. Chapters that apply a specific methodology summarize the successes and challenges of particular methods for quantifying the seasonal changes in ecosystem carbon, water and energy fluxes. The book will benefit global change researchers, modelers, and advanced students.

Download Spatial Modeling of Carbon Pools and Fluxes of Terrestrial Ecosystems Book in PDF, ePub and Kindle
The Carbon cycle holds center stage in many global change studies due to rising levels of atmospheric carbon dioxide and its role in influencing climate and determining food, fiber and wood supply for human use through plant productivity. Highly unusual variations in the global carbon balance over last few decades have prompted much research on the dynamics of carbon cycle. Terrestrial ecosystems play an important role in global carbon budgets. This book presents a detailed research study undertaken for improving our understanding of agroecosystem and forest carbon cycle in India. It includes a detailed assessment of past and ongoing landuse and landcover changes and their effects on agroecosystem carbon cycle in Indo-Gangetic plains and estimation of biomass, phytomass carbon and soil carbon pools, litterfall carbon flux, and long-term net carbon release in Indian forests at regional and national scales. The environmental, economic and societal importance of the carbon cycle has led to numerous research initiatives at national and international levels. This book is very useful and informative to researchers in the field of biogeochemical carbon cycle and global change studies.
