Executive Summary
The Heartland Inventory and Monitoring Network (HTLN) is a component of the National Park Service’s (NPS) strategy to improve park management through greater reliance on scientific information. The purposes of this program are to design and implement long-term ecological monitoring and provide information for park managers to evaluate the integrity of park ecosystems and better understand ecosystem processes. Concerns over declining surface water quality have led to the development of various monitoring approaches to assess stream water quality. Freshwater streams in network parks are threatened by numerous stressors, most of which originate outside park boundaries. Stream condition and …

Anthropogenic disturbances may be increasing jellyfish populations globally. Epibenthic jellyfish are ideal organisms for studying this phenomenon due to their sessile lifestyle, broad geographic distribution, and prevalence in near-shore coastal environments. There are few studies, however, that have documented epibenthic jellyfish abundance and measured their impact on ecological processes in tropical ecosystems. In this study, the density and size of the upside-down jellyfish (Cassiopea spp.) were measured in Codrington Lagoon, Barbuda. A sediment core incubation study, with and without Cassiopea, also was performed to determine their impact on benthic oxygen and nutrient fluxes. Densities of Cassiopea were 24–168 …
Non-Compliance In Marine Reserves: Measuring The Drivers Of Behavior Among Recreational Fishermen Within The Great Barrier Reef Marine Park, Nick Manning
Independent Study Project (ISP) Collection
The Great Barrier Reef Marine Park (GBRMP) provides outstanding ecological, cultural, social, and economic services to the number of communities that use it. Most of the park is regulated via a zoning system designed to protect its biodiversity and ensure the sustainable use of its resources (GBRMPA, 2004). Like any social institution, zoning regulations rely heavily on compliance in order to be effective. Recreational fishing on the GBRMP accounts for most of the noncompliance behavior associated with zoning (Arias and Sutton, 2013). Thus, understanding fishers compliance behavior is central to understanding how to best manage these areas. Using results from …
Wetland Hydrodynamics And Long-Term Use Of Spring Migration Areas By Lesser Scaup In Eastern South Dakota, Sharon N. Kahara, Steven R. Chipps
Wetland Hydrodynamics And Long-Term Use Of Spring Migration Areas By Lesser Scaup In Eastern South Dakota, Sharon N. Kahara, Steven R. Chipps
Great Plains Research: A Journal of Natural and Social Sciences
Lesser scaup (Aythya affinis [Eyton]) populations remain below their long-term average despite improved habitat conditions along spring migration routes and at breeding grounds. Scaup are typically associated with large, semipermanent wetlands and exhibit regional preferences along migration routes. Identifying consistently used habitats for conservation and restoration is complicated by irregular wetland availability due to the dynamic climate. We modeled long-term wetland use by lesser scaup in eastern South Dakota based on surveys conducted during below-average (1987-1989) and above-average (1993-2002) water condition years. Wetland permanence, longitude, and physiographic region were all significant determinants of use (P < 0.01). Long-term use was best described by a quadratic equation including wetland surface area variability, an index of wetland hydrodynamics that is linked to productivity, biodiversity, and value to waterfowl. Contrary to previous findings, our study shows that over the long term, lesser scaup are more than twice as likely to use permanent wetlands as they are semipermanent wetlands. The northern region of South Dakota's Prairie Coteau, which holds the highest density of hydrologically dynamic permanent wetlands, should be considered an area of conservation concern for lesser scaup. The criteria we identified may be used to identify important lesser scaup habitats in other regions of the Prairie Pothole Region.

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298
The studies in recent years (2000-2011) have allowed to make more precise the list and ranges of Mongolian fish. This is connected with new findings as well as the continuing process of invasion of alien species. Climate change and increase of human impact transformed ranges and local distribution of fish during last 30 years. Bias on ratio of ecological guilds, number of pathological findings are increasing, and declining of local diversity, rate of growth and fecundity of many species of fish are observed. In the course of long-term observation was confirmed periodically drying of waters of the Central Asian Lake …

Dickey-Lincoln School Lakes Project
The Dickey Lincoln School Lakes Project is a proposed multipurpose project located on the upper reaches of the St. John River in Aroostook County, Maine. Development would consist of two dams with associated reservoirs and hydroelectric generating facilities, five dikes and transmission lines. A more detailed description of the proposed project and its associated impacts is contained within the Revised Draft Environmental Impact Statement for the proposed project.

Dickey-Lincoln School Lakes Project
The U.S. Departments of the Interior and Energy have conducted system planning, location, and environmental studies for the transmission facilities required for the Dickey-Lincoln School Hydroelectric Project. These studies of many alternate routes have resulted in identification of a proposed transmission line route, and an environmental impact statement as required by the National Environmental Policy Act of 1969. This report, one of several covering various topical areas, is published as an appendix to that statement.

Two dams are proposed on the St. John River in northern Maine: Dickey, a high earth filled dam immediately above the confluence of the Allagash with the St. John, will have an installed generating capacity of 760 MW; and Lincoln School Dam, 11 miles downstream, a capacity of 70 MW. These dams are scheduled for completion during the mid 1980's. The U.S. Corps of Engineers, New England Division, has been allocated funds to design the project and prepare their own environmental impact statement. This report (Transmission Reconnaissance Studies) discusses alternative transmission facilities needed to connect the project with the New …

This report summarizes the results of system planning, environmental, and location studies for transmission facilities associated with the proposed Dickey-Lincoln School Lakes Project in northern Maine. The studies recommend the construction of two 345-kV transmission circuits from a substation near the project along a route through western Maine into northern New Hampshire and Vermont. The plan will integrate the power produced by the project into the New England Power Pool Transmission System. Five alternate integration plans were identified and studied. Of the five plans, the recommended plan, which calls for the lines to be suspended from a single row of …

Dickey-Lincoln School Lakes Project
This introduction of the St. John River watershed is situated in a transitional zone between the Boreal Forest Formation and the Eastern Deciduous Forest Formation. Second-growth forests representative of these two ecosystems cover extensive areas of the project site. The boreal forest forms a broad transcontinental belt in northern North America and Eurasia, with southern montane extensions. This northern forest is characterized by evergreen, coniferous trees, predominately spruce-fir The eastern deciduous forest, composed of broad-leaved hardwoods, extends throughout the eastern United States except Florida (Dasmann, 1968; Oosting, 1956).

The Fresh-Water Mussel Industry Of The Lower Tennessee River: Ecology & Future, Randall Grace
The Fresh-Water Mussel Industry Of The Lower Tennessee River: Ecology & Future, Randall Grace
Masters Theses & Specialist Projects
The fresh-water mussel industry of the Tennessee River is nearing an end. Overharvesting, habitat alterations, and pollution are the major contributors to the depletion of the mussel resource, upon which the shell industry is based. A history of unconcern by shell harvesters and weak conservation enforcement by governmental agencies, has left the major waterways of the United States nearly void of commercial clams. The lower Tennessee River presently supplies the mussel industry with nearly all the important species of mollusks. If this industry is to be maintained in the United States, ways to preserve and propagate the mussel population must …
