Health Preferences And Culturally Appropriate Strategies To Reduce Bear Bile Demand In Northern Vietnam, Shannon Randolph, Laura Zhang, Lena Tran, Mai Nguyen, Kimberley Ha

EnviroLab Asia

Animal products, such as pangolin scales, rhinoceros horns, tiger bones, and bear bile have been used in East Asian traditional medicine (TM) for more than 2,000 years. However, markets for medicinal wildlife products have expanded dramatically in countries like China and Vietnam in recent decades where economic prosperity has enabled a larger proportion of the population to afford wildlife products (Olmedo et al. 2017). Related new farming and commercialization practices to meet growing international demand pose environmental and human health risks. Animal products also symbolize shared cultural and historical medical practices that are distinct from the dominant Western medical model.

Nonlinear Reaction–Diffusion Process Models Improve Inference For Population Dynamics, Xinyi Lu, Perry J. Williams, Mevin B. Hooten, James A. Powell, Jamie N. Womble, Michael R. Bower

United States National Park Service: Publications

Partial differential equations (PDEs) are a useful tool for modeling spatiotemporal dynamics of ecological processes. However, as an ecological process evolves, we need statistical models that can adapt to changing dynamics as new data are collected. We developed a model that combines an ecological diffusion equation and logistic growth to characterize colonization processes of a population that establishes long-term equilibrium over a heterogeneous environment. We also developed a homogenization strategy to statistically upscale the PDE for faster computation and adopted a hierarchical framework to accommodate multiple data sources collected at different spatial scales. We highlighted the advantages of using a …

Ecotourism And The Middle East: Lessons In Development, Andrew Ver Steeg

Dartmouth Undergraduate Journal of Politics, Economics and World Affairs

In this paper I hope to introduce the reader to the aims of the ecotourism industry, its different actors, and some of its pitfalls and potential. I then turn discussion to the unique successes and challenges of developing the ecotourism sector in two nations that have already done much to lead the field in the Middle East, Jordan and Oman. I conclude with larger lessons and recommendations that have relevance for the Middle East as a whole while arguing that, though it may face some challenges, ecotourism has the potential to sustainably and sensitively aid the development of Middle Eastern …

Drones As A Tool To Monitor Human Impacts And Vegetation Changes In Parks And Protected Areas, Francisco Javier Ancin-Murguzur, Lorena Munoz, Christopher Monz, Vera H. Hausner

Environment and Society Faculty Publications

Increased visitation to protected areas could have adverse impacts on the conservation values in the protected areas, and therefore effective visitor monitoring methods are needed to meet the complex management challenges that arise. Collecting data on human impacts is highly time consuming, thus requiring more effective tools that allow for high-quality and long-term measurements. In this study, we show how unmanned aerial vehicles (i.e. UAV or drones) could be used to monitor tourism impacts in protected areas. Tourism has boomed in national parks in Norway in recent years, such as in Jotunheimen National Park for which this study applies. We …

Permafrost Hydrology Drives The Assimilation Of Old Carbon By Stream Food Webs In The Arctic, Jonathan A. O’Donnell, Michael P. Carey, Joshua C. Koch, Xiaomei Xu, Brett A. Poulin, Jennifer Walker, Christian E. Zimmerman

United States National Park Service: Publications

Permafrost thaw in the Arctic is mobilizing old carbon (C) from soils to aquatic ecosystems and the atmosphere. Little is known, however, about the assimilation of old C by aquatic food webs in Arctic watersheds. Here, we used C isotopes (d13C, D14C) to quantify C assimilation by biota across 12 streams in arctic Alaska. Streams spanned watersheds with varying permafrost hydrology, from ice-poor bedrock to ice-rich loess (that is, yedoma). We measured isotopic content of (1) C sources including dissolved organic C (DOC), dissolved inorganic C (DIC), and soil C, and (2) stream biota, including benthic biofilm and macroinvertebrates, and …

Analysis Of Environmental Performances Of Ferritization Method For The Treatment Of Copper-Ammonia Wastewater Under The Optimized Condition Via Rsm, Kanokporn Supong, Parnuwat Usapein, Pirapan Polburee

Applied Environmental Research

Copper-ammonia wastewater from industrial processes is an important form of hazardous waste that can contaminate water resources. The conventional hydroxide precipitation method used to remove copper complexes produces a large volume of unstable precipitates which still require further treatment. Ferritization is a powerful technique to remove bivalent cations from wastewater in the form of metal ferrites. This method is highly efficient in removal of metal complex ions; in addition, sludge resulting from this method is stable. The objective of this study was to investigate optimum conditions for ferritization using Response Surface Methodology (RSM). After optimal conditions were determined, the environmental …

Social Vulnerability To Large Wildfires In The Western Usa, Palaiologos Palaiologou, Alan A. Ager, Max Nielsen-Pincus, Cody Evers, Michelle A. Day

Environmental Science and Management Faculty Publications and Presentations

Federal land managers in the US can be informed with quantitative assessments of the social conditions of the populations affected by wildfires originating on their administered lands in order to incorporate and adapt their management strategy to achieve a more targeted prioritization of community wildfire protection investments. In addition, these assessments are valuable to socially vulnerable communities for quantifying their exposure to wildfires originating on adjacent land tenures. We assessed fire transmission patterns using fire behavior simulations to understand spatial variations across three diverse study areas (North-central Washington; Central California; and Northern New Mexico) to understand how different land tenures …

Trophic Models Of Seagrass Ecosystems In Maqueda Channel, Caramoan Peninsula, Philippines, Michael A. Clores, Michael A. Cuesta

Applied Environmental Research

Steady-state trophic models were constructed using the Ecopath with Ecosim software to examine the general status, development trends, and functional integrity of three extensive seagrass meadows located in Maqueda Channel of Caramoan Peninsula, Southern Luzon Island, Philippines. The results show that the ecosystems are composed of 23-24 functional groups with effective trophic levels extending from 1.00 to 3.76. Mixed trophic impacts show that decrease in the biomass of grazers Tripneustes gratilla (collector urchin) had a positive impact on the biomass of seagrasses. On the other hand, a positive effect on the benthic groups is expected with an assumed decrease in …

Commmunity, Ecology, And Modernity: Faunal Analysis Of Skútustaðir In Mývatnssveit, Northern Iceland, Megan Hicks

Dissertations, Theses, and Capstone Projects

This dissertation examines the archaeofaunal remains from Skútustaðir, a middle to high-status farm in Mývatnssveit, Northern Iceland, to understand the experience of rural communities and their ecologies during Iceland’s transition from regulated colonial exchange to a capitalist economy during the 17^th through 19^th centuries. Archaeofaunal analysis is used to reconstruct changes in the ways that people herded, hunted, and fished, providing insights into how they managed their local environments for subsistence and novel contexts of exchange. In addition to archaeofaunal analysis, primary textual sources are explored to assess how the Skútustaðir household and its rural community mobilized long-term …

Key Elements Of Environmental Justice In The Geothermal Power Plant Resistance Movement, Priyo Fajar Santoso, Bevaola Kusumasari

Jurnal Politik

Geothermal energy is currently considered as an environmentally friendly, renewable energy source. However, based on empirical data from various countries, geothermal energy production often results socioecological losses for the host community. Various environmental justice movements have emerged to protect environment by protestesting and providing a counter discourse against the dominant perception that geothermal energy is renewable and environmentally friendly. As Indonesian government put more effort to develop more geothermal power thermal across the country, more reactions also emerge and surprisingly include the critical one. This article aims to look at one of the critical reaction from community to counter the …
