Measuring Spatial And Temporal Shifts In Forest Structure And Composition In T High Elevation Beech Forests In Response To Beech Bark Disease In Great Smoky Mountains National Park, Lee Rubmle, Glenn Taylor, Joshua B. Grinath, Ashley B. Morris

United States National Park Service: Publications

Exotic forest pests and pathogens are among the most serious environmental threats to millions of hectares of forested land worldwide. Beech Bark Disease (BBD) is a non-native, pathogenic complex consisting of associations between scale insects and fungi. First confirmed in Great Smoky Mountains National Park (GRSM) in 1986, this complex has since threatened local high elevation beech forests, which are G-1 ranked (critically imperiled) forest communities where American beech (Fagus grandifolia Ehrh.) is a foundational tree species. In 1994, GRSM initiated the BBD Monitoring Protocol at 10 high elevation beech forest plots in the Park. The plots were sampled biennially …

Prey Of Reintroduced Fishers And Their Habitat Relationships In The Cascades T Range, Washington, Mitchell A. Parsons, Jeffrey C. Lewis, Jonathan N. Pauli, Tara Chestnut, Jason I. Ransom, David O. Werntz, Laura R. Prugh

United States National Park Service: Publications

Conservation and recovery of forest carnivores requires an understanding of their habitat requirements, as well as requirements of their prey. In much of the western United States, trapping and habitat loss led to extirpations of fishers (Pekania pennanti) by the mid-20th century, and reintroductions are ongoing to restore fishers to portions of their former range. Fisher recovery in Washington State has been limited by isolation from other populations, but other potentially important factors, such as diet of fishers in this region and prey availability, have not been thoroughly investigated. We collected hair samples from potential prey and fishers for stable …

Microwave Brightness Temperature Characteristics Of Three Strong Earthquakes In Sichuan Province, China, Feng Jing, Ramesh P. Singh, Yueju Cui, Ke Sun

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Passive microwave remote sensing technology is an effective means to identify the thermal anomalies associated with earthquakes due to its penetrating capability through clouds compared with infrared sensors. However, observed microwave brightness temperature is strongly influenced by soil moisture and other surface parameters. In the present article, the segmented threshold method has been proposed to detect anomalous microwave brightness temperature associated with the strong earthquakes occurred in Sichuan province, China, an earthquake-prone area with high soil moisture. The index of microwave radiation anomaly (IMRA) computed by the proposed method is found to enhance prior to the three strong earthquakes, 2008 …

Al-Balqa Journal for Research and Studies البلقاء للبحوث والدراسات

In the modern American short story the name of a character often illuminates certain associations—symbolic and otherwise. As the title reveals, it is the purpose of this paper to briefly analyze the significance of certain names in three selected American short stories written after World short stories written after world war I to see how, and in what capacity, names of characters contribute to the thematic and symbolic subtlety of the works in which they appear, and simultaneously to see how they help us understand the human character themselves. I have thus sharply limited myself to a selected aspect of …

The United States Love Affair With Maize: A National Security Issue?, Jared Kelly

Gettysburg Social Sciences Review

Maize is the most widely grown crop in the United States. The crop has a variety of applications being used for food, fuel, and in some industries. Maize is heavily integrated into the fabric of billions of lives across the world. The United States has encouraged the growth of a massive maize monoculture through the usage of government subsidies. However, this presents issues for the United States since it has created a large monoculture that is threatened by natural disasters, pest infestation, and bioterrorism attacks. Additionally, the cheap nature of the monoculture has additional externalities. Examples include decimated maize production …

Regional Forest Volume Estimation By Expanding Lidar Samples Using Multi-Sensor Satellite Data, Bo Xie, Chunxiang Cao, Min Xu, Barjeece Bashir, Ramesh P. Singh, Zhibin Huang, Xiaojuan Lin

Mathematics, Physics, and Computer Science Faculty Articles and Research

Accurate information regarding forest volume plays an important role in estimating afforestation, timber harvesting, and forest ecological services. Traditionally, operations on forest growing stock volume using field measurements are labor-intensive and time-consuming. Recently, remote sensing technology has emerged as a time-cost efficient method for forest inventory. In the present study, we have adopted three procedures, including samples expanding, feature selection, and results generation and evaluation. Extrapolating the samples from Light Detection and Ranging (LiDAR) scanning is the most important step in satisfying the requirement of sample size for nonparametric methods operation and result in accuracy improvement. Besides, mean decrease Gini …

Is Geographical Remoteness An Economic Disadvantage?, Jiaxuan Lu

Undergraduate Economic Review

Is the geographical location of a country deterministic to its level of economic development? Although economic geographers have been searching the answers to this question for decades, incongruities between different opinions still exist. This paper takes both theoretical and empirical approaches to provide a systematic answer to this question. Firstly, this paper uses industry-level gravity model of international trade to demonstrate that not all countries are negatively affected by geographical remoteness. Secondly, it employs a panel data of 83 countries from 2000 to 2017 and substantiates that while geographical remoteness decreases income levels and trade balances in OECD countries, it …

Spatial And Topological Analysis Of Urban Land Cover Structure In New Orleans Using Multispectral Aerial Image And Lidar Data, Shuxian Liu

LSU Master's Theses

Urban land use and land cover (LULC) mapping has been one of the major applications in remote sensing of the urban environment. Land cover refers to the biophysical materials at the surface of the earth (i.e. grass, trees, soils, concrete, water), while land use indicates the socio-economic function of the land (i.e., residential, industrial, commercial land uses). This study addresses the technical issue of how to computationally infer urban land use types based on the urban land cover structures from remote sensing data. In this research, a multispectral aerial image and high-resolution LiDAR topographic data have been integrated to investigate …

Brain Drain In The Mountain West, Ember Smith, Caitlin Saladino, William E. Brown

Economic Development & Workforce

This Fact Sheet highlights the effects of major shifts in geographic mobility patterns of highly-educated citizens in the Mountain West (Nevada, Utah, Arizona, New Mexico, and Colorado). The phenomenon, dubbed “brain drain” by experts, is characterized by the out-migration of a group of highly-educated people. “Brain gain” describes the opposite: when a location attracts highly-educated people. Several states are keeping and welcoming more highly-educated adults, while other states are rapidly losing talent. This migration pattern has important implications for social, political, and economic issues facing the country.

Plains Zebra (Equus Quagga) Behaviour In A Restored Population Reveals Seasonal Resource Limitations, Charli De Vos, Alison J. Leslie, Jason I. Ransom

United States National Park Service: Publications

A once abundant species, plains zebra (Equus quagga), is declining across much of sub-Saharan Africa. Reintroduction efforts at Majete Wildlife Reserve, Malawi, have resulted in rapid population increases, but little is known about how such populations resemble natural populations socially or behaviourally, and what those attributes may reveal about restoration success. Incorporating behavioural knowledge into conservation efforts is an important tool for managing the effects of habitat fragmentation and resource competition. The aim of this study was to quantify the daylight time budget of both family and bachelor bands of reintroduced plains zebra to determine if such behaviours …

Glacial Meltwater Modeling To Simulate Lake Water Budget (1996-2013) In Taylor Valley, Antarctica, Julian Michael Cross

Dissertations and Theses

The McMurdo Dry Valleys (MDV), the largest ice-free region (4,500 km²) in Antarctica, are a polar desert with an average annual temperature of -18ºC. In Taylor Valley, one of the MDV, closed-basin, perennially ice-covered lakes occupy the valley floor. Their water balance is controlled by inflow from glacial meltwater runoff and loss due to sublimation, making them sensitive indicators of climate. In this study, a physically-based model of glacier meltwater and lake ice sublimation is adapted to explain modern (1996 to 2013) lake-level variations. Meltwater model results were improved by the inclusion of MODIS remotely-sensed albedo measurements (E …

Predicting Livestock Depredation Risk By African Lions (Panthera Leo) In A Multi-Use Area Of Northern Tanzania, K. Beattie, E. R. Olson, B. Kissui, A. Kirschbaum, C. Kiffner

United States National Park Service: Publications

Human-wildlife conflicts, especially those involving large carnivores, are of global conservation and livelihood concern and require effective and locally-adapted prevention measures. Risk of lion attack on livestock (i.e. depredation) may vary seasonally and may be associated with variation in wild prey abundance or landscape characteristics. To test these competing hypotheses, we used a resource selection approach, and determined whether prey catchability (indicated by geo-spatial variables), or prey availability (indicated by modeled abundance recorded via camera traps) explained spatial and seasonal variation in livestock depredation risk by African lions on Manyara Ranch Conservancy, a multi-use area in northern Tanzania. Seasonal variation …

Remote Sensing Monitoring Of Vegetation Dynamic Changes After Fire In The Greater Hinggan Mountain Area: The Algorithm And Application For Eliminating Phenological Impacts, Zhibin Huang, Chunxiang Cao, Wei Chen, Min Xu, Yongfeng Dang, Ramesh P. Singh, Barjeece Bashir, Bo Xie, Xiaojuan Lin

Mathematics, Physics, and Computer Science Faculty Articles and Research

Fires are frequent in boreal forests affecting forest areas. The detection of forest disturbances and the monitoring of forest restoration are critical for forest management. Vegetation phenology information in remote sensing images may interfere with the monitoring of vegetation restoration, but little research has been done on this issue. Remote sensing and the geographic information system (GIS) have emerged as important tools in providing valuable information about vegetation phenology. Based on the MODIS and Landsat time-series images acquired from 2000 to 2018, this study uses the spatio-temporal data fusion method to construct reflectance images of vegetation with a relatively consistent …

Spatial And Non-Spatial Drivers For Design Thinking In Knowledge Ecosystems, Onur Mengi

Markets, Globalization & Development Review

The concept of knowledge ecosystems is an emerging arena to reconsider the design thinking processes from a perspective which comprises different levels of knowledge interaction, and how those are regulated by different dimensions. The issue of design thinking is the most relevant for creative industries emerging around creativity and knowledge and providing innovation, change and impact through interaction, however, existing research inadequately connects design thinking both to physical and non-physical dimensions of knowledge ecosystems. Despite knowledge interaction is vastly regarded as a face-to-face communication for design thinking at micro-scale, it appears and be proficient as it involves non-spatial drivers at …

Van Lipzig, Mattias Demuzere, Sabine Vanhuysse, Nicholus Mboga, Vernica Andreo, Robert W. Snow, Moritz Lennert

Geography Articles

The rapid and often uncontrolled rural–urban migration in Sub-Saharan Africa is transforming urban landscapes expected to provide shelter for more than 50% of Africa’s population by 2030. Consequently, the burden of malaria is increasingly affecting the urban population, while socio-economic inequalities within the urban settings are intensified. Few studies, relying mostly on moderate to high resolution datasets and standard predictive variables such as building and vegetation density, have tackled the topic of modeling intra-urban malaria at the city extent. In this research, we investigate the contribution of very-high-resolution satellite-derived land-use, land-cover and population information for modeling the spatial distribution of …

Landscapes Of War Permanently Altered Topography Is One Of The Casualties Of War, But Battlefields Can Also Be Of "Collateral Value", Todd R. Lookingbill, Peter D. Smallwood

Geography and the Environment Faculty Publications

But the rationale for creating battlefield parks has changed over the past 100 years, as have attitudes about battlefield conservation with a related emphasis on the physical landscapes themselves, leading to their management for multiple, layered assets through principles of constructive conservation. Existing battlefield parks provide perhaps the longest-standing examples of the evolution of landscapes of war toward generators of multiple ecosystem benefits. Moving from battlefield parks that, in some cases, have not seen warfare for hundreds of years, we examined landscapes of more recent conflict and considered the future collateral values that could be attained by establishing parks at …

For Food Space: Theorizing Alternative Food Networks Beyond Alterity, Renata Blumberg, Helga Leitner, Kirsten Valentine Cadieux

Department of Nutrition and Food Studies Scholarship and Creative Works

In response to calls by scholars to deepen theoretical engagement in research on Alternative Food Networks (AFNs), in this article we critically discuss and assess major theoretical approaches deployed in the study of AFNs. After highlighting the strengths and limitations of each theoretical approach, we provide an alternative framework – which we refer to as the Geographical Political Ecology of Food Systems – that integrates the contributions that have emerged in the study of the alternative geographies of food with an understanding of capitalist processes in the food system. We do this by bringing together literature on the political ecology …

Urban Informality, Environmental Xenophobia, And Infrastructures Of Citizenship: The Political Lives Of Nicaraguan Migrants In The Informal Settlement Of La Carpio, Costa Rica, Nikolai Alexander Alvarado

Electronic Theses and Dissertations

This dissertation examines urban politics, environmental justice, and infrastructure from the vantage point of South-South migration. It focuses on the work of Nicaraguan migrants living in the informal settlement of La Carpio in San José, Costa Rica, as they negotiate rights in the form of urban services. Nicaraguans in La Carpio have organized politically since 1993 to self-install, demand, and negotiate services such as potable water and electricity. In the process, they successfully compel local authorities to allocate these services and grant them an implicit recognition of their right to remain and live a decent life, regardless of their status. …

No. 42: The Role Of Infrastructure Access In Urban Household Vulnerability To Food Insecurity In Southern Cities, Cameron Mccordic, Bruce Frayne, James Sgro

Hungry Cities Partnership

The geographical concentration of poverty in informal neighbourhoods across cities is a common socioeconomic feature of the urban form. Many of these impoverished areas also suffer from limited access to urban infrastructure. Given the expense and planning necessary to develop urban infrastructure, these areas are socially vulnerable in part because of their exclusion from urban master plans. This vulnerability is made more severe by the knock-on impacts of limited infrastructure access on other aspects of human insecurity. This paper uses HCP data to assess the predictive relationship between household infrastructure access and food insecurity across five case-study cities (Mexico City, …

No. 40: Food Retailing Transitions And New Retail Businesses In Nanjing, China, Ning Dai, Zhenzhong Si

Hungry Cities Partnership

China’s food retailing sector is transitioning towards a digitalized consumer society in the context of widespread food safety anxiety. At the forefront of this transition is an innovative form of food retailing called New Retail Businesses (NRBs). Based on field research and interviews with key stakeholders in Nanjing, this study outlines distinctive features of NRBs in contrast to the conventional food system. It also points out that NRBs have shared goals with the government’s Vegetable Basket Project. Thus the implementation of this project in Nanjing has propelled the growth of a local NRB. Equipped with an integrated ecological food supply …

No. 38: Reconceptualizing Informal Economic Governance: Implications From Cape Town, South Africa, Graeme Young

Hungry Cities Partnership

As awareness of the centrality of informality in urban development processes in the Global South is slowly incorporated into the international development agenda, a full understanding of the myriad ways in which informal economic activity is governed has become increasingly urgent. This discussion paper seeks to address this need through an analysis of informal economic governance in Cape Town, South Africa. It first outlines a general theoretical framework for understanding the governance of informal economies that focuses on the logics that inform governance, the systems in which governance take place, the modes in which governance operates, and the forms that …
