The Role Of The Ocean Industry In The Chinese National Economy: An Input-Output Analysis, Rui Zhao
The Role Of The Ocean Industry In The Chinese National Economy: An Input-Output Analysis, Rui Zhao
Working Papers
The OEAS (Ocean Economy Accounting System) has been established in China for 6 years. However, the economic impact of the ocean economy in China’s national economy has not yet been understood clearly at the national or regional levels. The direct impact of ocean industries in China at national and regional levels has been compiled for the period of 2001-2011, but it is still unclear what the overall economic impacts of ocean industries are in the national economy, and how the ocean industries interact with other industries in the national economy. China is similar to other ocean countries in that, - …

Quantifying The Effects Of Pesticide Exposure On Annual Reproductive Success Of Birds, Matthew A. Etterson, Richard S. Bennett
Quantifying The Effects Of Pesticide Exposure On Annual Reproductive Success Of Birds, Matthew A. Etterson, Richard S. Bennett
United States Environmental Protection Agency: Publications
The Markov chain nest productivity model (MCnest) was developed for quantifying the effects of specific pesticide‐use scenarios on the annual reproductive success of simulated populations of birds. Each nesting attempt is divided into a series of discrete phases (e.g., egg laying, incubation, nestling rearing), and results from avian toxicity tests are used to represent the types of effects possible in the field during each breeding phase. The expected exposure dose each day throughout the breeding season can be compared to the toxicity thresholds assigned to each breeding phase to determine whether the nest attempt is at risk. The primary output …

The goal of the Loyola Weather Service (lws) project is to design and build a system of functioning environmental monitoring widgets that can intelligently and autonomously control the environment around them based on set thresholds and triggers. The widgets will also have the ability to aggregate their data and easily display this data in various ways: through a user interface in the room that the widget is placed, via a web application, and programmatically via a RESTful web service.
Understanding Effects Of Changes In Land Use, Environmental Parameters, Habitat Characteristics On The Great Basin Aquatic Invertebrates Using Ecological Stoichiometric Theory, Knut Mehler
UNLV Theses, Dissertations, Professional Papers, and Capstones
Many freshwater ecosystems in the Great Basin have undergone dramatic alteration over the past decades due to groundwater withdrawal, water diversion and changes in land use. These changes have affected benthic food web dynamics by altering the availability of chemical key elements for primary and secondary producers, by loss of biodiversity and extinction of endemic species. However, only few studies are available that addresses the link between changes in land use, habitat characteristics and its effects on benthic macroinvertebrates (BMI) communities comprehensively and little attention has been given to integrating physiochemical aspects to link ecosystem functions.
This dissertation analyzes the …

Enhancing Coastal Resilience: Perspectives On Valuing Ri Coastal Lands, Kyle Nyskohus
Enhancing Coastal Resilience: Perspectives On Valuing Ri Coastal Lands, Kyle Nyskohus
Honors Projects in Science and Technology
This paper discusses coastal resilience as an organizing framework for future policymaking, coastal planning, and insurance decisions, and explores the different perspectives of the value of ecosystems held by various stakeholders in Rhode Island’s coastal communities. A grounded theory approach was used in an effort to abstract general insights from the substantive but isolated areas of coastal management and economics. Special attention is given to the perspectives of municipal decision makers, the National Flood Insurance Program, natural economists, and real estate developers. We have (1) conducted a statistical analysis of environmental spending of RI towns, (2) identified key models for …

Hidden Markov Models For Estimating Animal Mortality From Anthropogenic Hazards, Matthew A. Etterson
Hidden Markov Models For Estimating Animal Mortality From Anthropogenic Hazards, Matthew A. Etterson
United States Environmental Protection Agency: Publications
Carcass searches are a common method for studying the risk of anthropogenic hazards to wildlife, including nontarget poisoning and collisions with anthropogenic structures. Typically, numbers of carcasses found must be corrected for scavenging rates and imperfect detection. Parameters for these processes (scavenging and detection) are often estimated using carcass distribution trials in which researchers place carcasses in the field at known times and locations. In this manuscript I develop a variety of estimators based on multi-event or hidden Markov models for use under different experimental conditions. I apply the estimators to two case studies of avian mortality, one from pesticide …

Examining Rapid Onset Drought Development Using The Thermal Infrared–Based Evaporative Stress Index, Jason A. Otkin, Martha C. Anderson, Christopher Hain, Iliana E. Mladenova, Jeffrey B. Basara, Mark Svoboda
National Drought Mitigation Center: Faculty Publications
Reliable indicators of rapid drought onset can help to improve the effectiveness of drought early warning systems. In this study, the evaporative stress index (ESI), which uses remotely sensed thermal infrared imagery to estimate evapotranspiration (ET), is compared to drought classifications in the U.S. Drought Monitor (USDM) and standard precipitation-based drought indicators for several cases of rapid drought development that have occurred across the United States in recent years. Analysis of meteorological time series from the North American Regional Reanalysis indicates that these events are typically characterized by warm air temperature and low cloud cover anomalies, often with high winds …

Review Of The Negative Influences Of Non-Native Salmonids On Native Fish Species, Kelly C. Turek, Mark A. Pegg, Kevin L. Pope
Review Of The Negative Influences Of Non-Native Salmonids On Native Fish Species, Kelly C. Turek, Mark A. Pegg, Kevin L. Pope
Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications
Non-native salmonids are often introduced into areas containing species of concern, yet a comprehensive overview of the short- and long-term consequences of these introductions is lacking in the Great Plains. Several authors have suggested that non-native salmonids negatively influence species of concern. The objective of this paper is to review known interactions between non-native salmonids and native fishes, with a focus on native species of concern. After an extensive search of the literature, it appears that in many cases non-native salmonids do negatively influence species of concern (e.g., reduce abundance and alter behavior) via different mechanisms (e.g., predation and competition). …

An Integrated Research Approach To The Development Of Fungal Isolates As Bioherbicides For The Control Of Woody Weeds, Patrick Mershon
An Integrated Research Approach To The Development Of Fungal Isolates As Bioherbicides For The Control Of Woody Weeds, Patrick Mershon
Independent Study Project (ISP) Collection
Prickly acacia (Acacia nilotica) is an invasive weed tree in Australia, ranked seventh on the list of Weeds of National Significance because of its aggressiveness and its economic and environmental impacts. The significant downsides to manual and chemical control of this species drove the search for a biological control mechanism. Surveying and sampling stands of A. nilotica naturally exhibiting disease symptoms yielded several native Australian fungi capable of pathogenesis in this species, which are currently under assessment as potential bioherbicides for this weed. Three field trials were established at the same site in order to further advance current …

Aquatic plant surveys were conducted at 22 waterbodies located within the Bureau of Land Management’s Medford District during the summer of 2012. Sites included eleven lakes, ponds or reservoirs and six reaches along the Rogue and Applegate Rivers. Five sampling areas surveyed during 2010 and 2011 were revisited to determine the extent of known non-native species infestations, positively identify rare species, or verify the absence of an expected non-native species. Plant specimens were collected at up to 50 sites at each waterbody using plant rakes or by observation. The non-native submersed species curly leaf pondweed (Potamogeton crispus) and …
Investigations Of Phytoplankton Diversity In Chesapeake Bay, Todd Arthur Egerton
Investigations Of Phytoplankton Diversity In Chesapeake Bay, Todd Arthur Egerton
Biological Sciences Theses & Dissertations
Characterizing the diversity of a community in relation to environmental conditions and ecosystem functions are core concepts in ecology. While decades of research have led to a growing comprehension of diversity in many ecosystems, our understanding in aquatic habitats and microbial organisms remains relatively limited. Phytoplankton represent a diverse and important group that contribute approximately half of global primary productivity and are intrinsically connected to changing environmental conditions, especially in systems as dynamic as estuaries. To better understand the ecological processes governing phytoplankton composition and diversity, spatial and temporal patterns of environmental parameters and their relation to the algal community …
