Thenkabail Received: 4 November 2015; Accepted: 15 February 2016; Published: 19 February 2016 Abstract: A large-scale re-vegetation supported by the Grain for Green Project (GGP) has greatly changed local eco-hydrological systems, with an impact on soil moisture conditions for the Chinese Loess Plateau. It is important to know how, exactly, re-vegetation influences soil moisture conditions, which not only crucially constrain growth and distribution of vegetation, and hence, further re-vegetation, but also determine the degree of soil desiccation and, thus, erosion risk in the region. In this study, three eco-environmental factors, which are Soil Water Index (SWI), the Normalized Difference Vegetation Index (NDVI), and precipitation, were used to investigate the response of soil moisture in the one-meter layer of top soil to the re-vegetation during the GGP. -
Quantifying Trends of Land Change in Qinghai-Tibet Plateau During 2001–2015
remote sensing Article Quantifying Trends of Land Change in Qinghai-Tibet Plateau during 2001–2015 Chao Wang, Qiong Gao and Mei Yu * Department of Environmental Sciences, University of Puerto Rico, Rio Piedras, San Juan, PR 00936, USA; [email protected] (C.W.); [email protected] (Q.G.) * Correspondence: [email protected]; Tel.: +1-787-764-0000 Received: 1 September 2019; Accepted: 17 October 2019; Published: 20 October 2019 Abstract: The Qinghai-Tibet Plateau (QTP) is among the most sensitive ecosystems to changes in global climate and human activities, and quantifying its consequent change in land-cover land-use (LCLU) is vital for assessing the responses and feedbacks of alpine ecosystems to global climate changes. In this study, we first classified annual LCLU maps from 2001–2015 in QTP from MODIS satellite images, then analyzed the patterns of regional hotspots with significant land changes across QTP, and finally, associated these trends in land change with climate forcing and human activities. The pattern of land changes suggested that forests and closed shrublands experienced substantial expansions in the southeastern mountainous region during 2001–2015 with the expansion of massive meadow loss. Agricultural land abandonment and the conversion by conservation policies existed in QTP, and the newly-reclaimed agricultural land partially offset the loss with the resulting net change of 5.1%. Although the urban area only expanded 586 km2, mainly at the expense of agricultural − land, its rate of change was the largest (41.2%). Surface water exhibited a large expansion of 5866 km2 (10.2%) in the endorheic basins, while mountain glaciers retreated 8894 km2 ( 3.4%) mainly in the − southern and southeastern QTP. -

1 Desorption and Adsorption of Subsurface Shale Gas
Desorption and Adsorption of Subsurface Shale Gas DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Fengyang Xiong, M.S. Graduate Program in School of Earth Sciences The Ohio State University 2020 Dissertation Committee: Joachim Moortgat, Advisor David Cole Tom Darrah Derek Sawyer 1 Copyrighted by Fengyang Xiong 2020 2 Abstract Storage of subsurface shale gas is challenging to characterize because nanoporous shales consist of almost all commonly observed minerals and develop a wide pore size distribution of 0.4 nm to 1 ��. Petroleum geoscientists classify the subsurface shale gas into three components: free gas in the pore space, adsorbed gas on mineral surfaces, and dissolved gas in formation fluids and organic matter. Based on investigations of shale gas plays in the United States, the adsorbed gas can contribute up to 85% of the total shale gas- in-place (GIP). And the storage of adsorbed shale gas, which mainly consists of methane, is determined by multiple geological properties, e.g., pore structure, mineral composition, temperature, pressure, and water saturation. These complex multivariate relationships complicate the assessment of subsurface adsorbed gas, which is still challenging for exploration geoscientists to quantitatively characterize. In this dissertation, we investigate the pore structure of shales, including the roles of organic matter, mainly insoluble kerogen, and inorganic minerals in pore development using Soxhlet extraction and low-pressure nitrogen and carbon dioxide adsorption isotherms. We then study the relationship between in-situ desorbed gas and mineralogy on large core samples. Most importantly, we propose an experimental procedure to estimate the pressure-dependent density of adsorption, which will significantly improve future estimates of adsorbed gas in shale GIP assessment. -

Mistletoes of North American Conifers
United States Department of Agriculture Mistletoes of North Forest Service Rocky Mountain Research Station American Conifers General Technical Report RMRS-GTR-98 September 2002 Canadian Forest Service Department of Natural Resources Canada Sanidad Forestal SEMARNAT Mexico Abstract _________________________________________________________ Geils, Brian W.; Cibrián Tovar, Jose; Moody, Benjamin, tech. coords. 2002. Mistletoes of North American Conifers. Gen. Tech. Rep. RMRS–GTR–98. Ogden, UT: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 123 p. Mistletoes of the families Loranthaceae and Viscaceae are the most important vascular plant parasites of conifers in Canada, the United States, and Mexico. Species of the genera Psittacanthus, Phoradendron, and Arceuthobium cause the greatest economic and ecological impacts. These shrubby, aerial parasites produce either showy or cryptic flowers; they are dispersed by birds or explosive fruits. Mistletoes are obligate parasites, dependent on their host for water, nutrients, and some or most of their carbohydrates. Pathogenic effects on the host include deformation of the infected stem, growth loss, increased susceptibility to other disease agents or insects, and reduced longevity. The presence of mistletoe plants, and the brooms and tree mortality caused by them, have significant ecological and economic effects in heavily infested forest stands and recreation areas. These effects may be either beneficial or detrimental depending on management objectives. Assessment concepts and procedures are available. Biological, chemical, and cultural control methods exist and are being developed to better manage mistletoe populations for resource protection and production.

Renewable Energy in the National Park Service
RENEWABLE ENERGY IN THE NATIONAL PARK SERVICE INTRODUCTION The National Park Service is the steward of some of the world’s finest natural and cultural resources and is regarded by many people as the premier resource conservation agency in the United States if not the world. The mission of the National Park Service is clearly defined in the organic act of 1916. to conserve the scenery and the natural and historic objects and the wildlife therein, and to provide for the enjoyment of the same in such a manner and by such means as will leave them unimpaired for the enjoyment of future generations. This strong mandate and policy direction has always emphasized protecting and conserving this country’s cultural and natural resources while providing the visiting public with opportunities to learn about these resources. When the National Park Service celebrated its 75th anniversary in 1991, it charted a course for how it would accomplish its mission into the next century. The resulting vision document titled National Parks for the 21st Century: The Vail Agenda, provides strategic objectives and directions for the future management of the National Park Service. Incorporating sustainability and sustainable design was recommended in The Vail Agenda as one method of meeting challenges that currently face the National Park Service. The Park Service defines sustainable design as a design that meets the needs of the present without compromising the ability of future generations to meet their own needs. Many people feel this definition bears a striking resemblance to the organic act – the founding legislation for the National Park Service.
