Heterogeneity Of Avian Breeding Habitat On Grazing Lands Of The Northern Great Plains, Maggi S. Sliwinski 2017 University of Nebraska-Lincoln

Heterogeneity Of Avian Breeding Habitat On Grazing Lands Of The Northern Great Plains, Maggi S. Sliwinski

Dissertations & Theses in Natural Resources

Native rangelands in the Great Plains are largely privately owned and used for beef production. Vegetation heterogeneity is important for maintaining biodiversity, but private land may be more homogenous than desired. My research had two components: 1) to examine whether a variety of grazing strategies created vegetation heterogeneity in a large, intact rangeland, and 2) to understand beef producers’ attitudes about vegetation heterogeneity.

First, I sampled vegetation structure, composition, and bird abundance at multiple plots on eleven management units in Cherry County, Nebraska. Units were managed with commonly used grazing strategies (e.g., short-duration grazing and season-long continuous grazing). I ...


Problematizing Socio-Scientific Issues: An Approach To Understanding Student Decision-Making Using Construal Level Theory, Ashley M. Peterson 2017 University of Nebraska-Lincoln

Problematizing Socio-Scientific Issues: An Approach To Understanding Student Decision-Making Using Construal Level Theory, Ashley M. Peterson

Dissertations & Theses in Natural Resources

Socio-scientific issues (SSIs) are challenges at the intersection of science and everyday life that require use of scientific knowledge, argumentation skills, personal values, and morals to articulate science-informed decisions. While addressing SSIs, the ways in which individuals define a problem will influence the solution or decision reached. The problem definition can differ along many dimensions, including content and construal level. A construal is a mental construction of the past and future, other places and people, and unlikely events. Construal Level Theory (CLT) suggests pro-environmental intentions are associated with abstract situations. I explore the application of CLT to teaching and learning ...


The Giving Trees: The (Un)Sustainability Of Palm Oil In Indonesia, Amber Rosche 2017 Pepperdine University

The Giving Trees: The (Un)Sustainability Of Palm Oil In Indonesia, Amber Rosche

Seaver College Research And Scholarly Achievement Symposium

Palm oil is the main source of cooking oil for much of Africa, Asia and Brazil. Due to the increasingly high demand for palm oil, countries such as Indonesia and Malaysia have cleared millions of acres of tropical rainforests to create space for oil palm plantations. This deforestation has led to extreme environmental and social concerns such as the burning of peatlands, the endangerment of a number of species, including the Sumatran Tiger, rhinos and orangutans, and the displacement of native populations. Indonesia is the world’s largest consumer and producer of palm oil, producing almost half of the world ...

With increasing public demand for clear air and clean water, many inside and outside Washington, D.C., have suggested that federal farm income support should be tied to enhanced conservation practices.


Measuring Plant-Wide Energy Savings, J. Kelly Kissock, Carl Eger 2017 University of Dayton

Measuring Plant-Wide Energy Savings, J. Kelly Kissock, Carl Eger

J. Kelly Kissock

This paper presents a general method for measuring plant-wide industrial energy savings and demonstrates the method using a case study from an actual industrial energy assessment. The method uses regression models to characterize baseline energy use. It takes into account changes in weather and production, and can use sub-metered data or whole plant utility billing data. In addition to calculating overall savings, the method is also able to disaggregate savings into components, which provides additional insight into the effectiveness of the individual savings measures. Although the method incorporates search techniques and multi-variable least-squares regression, it is easily implemented using data ...


Tracking Decadal Changes In Striped Bass Recruitment: A Calibration Study Of Seine Surveys In Chesapeake Bay, Mary C. Fabrizio, Troy D. Tuckey, Olivia M. Philips, Brian K. Gallagher 2017 Virginia Institute of Marine Science

Tracking Decadal Changes In Striped Bass Recruitment: A Calibration Study Of Seine Surveys In Chesapeake Bay, Mary C. Fabrizio, Troy D. Tuckey, Olivia M. Philips, Brian K. Gallagher

Reports

In this study we estimated calibration factors necessary to maintain the long‐term integrity of the juvenile striped bass surveys in the Chesapeake Bay region. These surveys provide annual indices of recruitment (estimated as juvenile fish abundance in summer) and are used by fisheries managers in Virginia and Maryland to inform adjustments of annual harvest limits for striped bass from the commercial and recreational fisheries in Chesapeake Bay. During the multi‐decadal history of the survey, a potentially influential change occurred: VIMS deployed a net (the VA net) with a mesh material that differed from the standard net that MD ...


Estimating Relative Abundance Of Young-Of-The-Year American Eel, Anguilla Rostrata, In The Virginia Tributaries Of Chesapeake Bay, Spring 2016, Mary C. Fabrizio, Troy D. Tuckey 2017 Virginia Institute of Marine Science

Estimating Relative Abundance Of Young-Of-The-Year American Eel, Anguilla Rostrata, In The Virginia Tributaries Of Chesapeake Bay, Spring 2016, Mary C. Fabrizio, Troy D. Tuckey

Reports

American Eel (Anguilla rostrata) is a valuable commercial species along the Atlantic coast of North America from New Brunswick to Florida. In the U.S., harvests have declined, with similar patterns occurring in the Canadian Maritime Provinces (Meister and Flagg 1997). An average of 62% of the annual landings of U.S. commercial harvest since 1993 have come from the Chesapeake Bay (personal communication from the National Marine Fisheries Service, Fisheries Statistics Division, 9 February 2015). In 2013, Virginia commercial landings were approximately 100,298 lbs; since mandatory reporting began in 1993, average annual landings in Virginia have been 193 ...

Changes In Cormorant Populations In The Strait Of Georgia, British Columbia, 1955-2015, Harry R. Carter, Trudy A. Chatwin, Mark C. Drever

Salish Sea Ecosystem Conference

Between 1987 and 2000, nesting populations of Pelagic Cormorant (Phalacrocorax pelagicus; PECO) and Double-crested Cormorant (P. auritus; DCCO) declined in the Strait of Georgia, BC. This northern section of the Salish Sea is a rapidly urbanizing area, and piscivorous birds are important indicators of ecosystem health. To update population status, we conducted a complete survey of 35 PECO and 23 DCCO colonies in July 2014 and opportunistic surveys of some colonies between 2001 through 2015. The PECO population decreased from ~2100-2400 nests in 1959-1987 to ~1100 nests by about 2000, and then rose slightly to ~1600 nests by 2015. The ...

Advances In Salish Sea Acoustic Telemetry: 2015 Array Deployments And Promising Transmitter Performance, Erin L. Rechisky, David W. Welch, Aswea D. Porter, Paul Winchell

Salish Sea Ecosystem Conference

The first fish tracking arrays were deployed in the Salish Sea over a decade ago. These arrays have yielded a rich data set which have provided the first direct estimates of early marine-survival and migratory behavior for acoustic-tagged juvenile sockeye, Chinook, Coho and steelhead >130 mm in fork length (FL). In spring of 2015, as part of the Salish Sea Marine Survival Project, the Pacific Salmon Foundation, the Ocean Tracking Network and Kintama Research deployed additional arrays in the Discovery Islands and Johnstone Strait (north of the Strait of Georgia) to provide higher resolution survival data. These new arrays use ...


Simulating The Dispersal Of Invasive Clams In A Freshwater Lake Using A Three-Dimensional Hydrodynamic Model; A Prototype For Simulating Invasions In Marine Ecosystems, Elizabeth Kilanowski, Lambert Rubash 2017 Raincoast GeoResearch

Simulating The Dispersal Of Invasive Clams In A Freshwater Lake Using A Three-Dimensional Hydrodynamic Model; A Prototype For Simulating Invasions In Marine Ecosystems, Elizabeth Kilanowski, Lambert Rubash

Salish Sea Ecosystem Conference

The discovery of several populations of an invasive Asian clam (corbicula fluminea) in Lake Whatcom, the drinking water source for approximately 100,000 people in Northern Washington State, created a need among elected officials, local government staff, and the public for a better understanding of lake hydrodynamics during the reproductive season for the Asian clam, and for times when Quagga and Zebra mussel invasions are likely. Seasonal vertical thermal stratification of the lake and a desire to predict likely locations of additional clam populations or of new populations of mussels led to the choice of a model that could be ...

Relative Abundance Of Sixgill Sharks (Hexanchus Griseus) In Elliott Bay, Seattle, Washington, Denise Griffing, Shawn Larson, Jeff Christiansen, Joel Hollander, Tim Carpenter

Salish Sea Ecosystem Conference

The Sixgill Shark Research Project is designed to address gaps in the body of scientific knowledge on bluntnose sixgill sharks (Hexanchus griseus) in Puget Sound. This project utilizes three interwoven techniques: (1) genetics research, (2) visual marker tagging, and (3) video analysis. Seattle Aquarium biologists monitor sixgill shark sightings reported by local divers (since 1999) and study their relative abundance in Elliott Bay under the Aquarium’s pier (since 2003). Here we report on our findings of relative abundance.

Bluntnose sixgills are a species of conservation concern. Sixgills are listed as “near threatened” on the IUCN Red List. Living mainly ...


Movements Of Sub-Adult Chinook Salmon (Oncorhynchus Tshawytscha) In Puget Sound, Washington, As Indicated By Hydroacoustic Tracking, Anna N. Kagley, Joseph Smith, Kurt Fresh, Kinsey Frick, Thomas Quinn 2017 NOAA Fisheries

Movements Of Sub-Adult Chinook Salmon (Oncorhynchus Tshawytscha) In Puget Sound, Washington, As Indicated By Hydroacoustic Tracking, Anna N. Kagley, Joseph Smith, Kurt Fresh, Kinsey Frick, Thomas Quinn

Salish Sea Ecosystem Conference

Alternative forms of migratory behavior can have substantial consequences for the growth, survival, and fitness of the individuals involved. Salmonids vary in the tendency of individuals to migrate to marine waters (anadromy) or remain in freshwater habitats. In addition, substantial variation in migratory patterns can exist among anadromous and resident species. This talk summarizes our use of hydroacoustic telemetry to investigate the movement patterns of anadromous Chinook salmon Oncorhynchus tshawytscha remaining in the marine waters of Puget Sound after ocean entry rather than continuing out to the coastal waters of the North Pacific Ocean, as is typical of the species ...


Holding The Line, To Let Shorelines Move Naturally, Kyle Loring 2017 Friends of the San Juans

Holding The Line, To Let Shorelines Move Naturally, Kyle Loring

Salish Sea Ecosystem Conference

This poster will identify mechanisms for limiting the impacts of residential development on the natural functions of marine shorelines.

First, it will share the results from two recent legal cases that successfully prevented the unnecessary bulkheading of a documented surf smelt spawning beach on San Juan Island. Friends of the San Juans appealed two local permit approvals to the Shoreline Hearings Board. The local permits authorized two-tiered armoring that extended nearly 20 total feet in height and would have removed most of the vegetation that shaded the beaches and supplied insects for juvenile Chinook salmon in an area identified as ...


Synthesis Of Results From Twelve Puget Sound Regulatory Effectiveness And Incentive Investigations, Aimee Kinney, Tessa Francis, Jeff Rice 2017 University of Washington Puget Sound Institute

Synthesis Of Results From Twelve Puget Sound Regulatory Effectiveness And Incentive Investigations, Aimee Kinney, Tessa Francis, Jeff Rice

Salish Sea Ecosystem Conference

Between 2011 and 2014, the Puget Sound Marine and Nearshore Grant Program funded twelve projects relating to shoreline regulatory and incentive programs. Here we provide an overview of overarching themes that emerged from a review of the projects in aggregate. Despite the different approaches to problem identification, data collection, and analysis in these investigations, the conclusions reached and recommendations made are remarkably similar. Key findings and implications of our analysis relate to: (1) armoring compliance rates; (2) compliance monitoring methodologies; (3) local Shoreline Master Program (SMP) capacity limitations; (4) SMP implementation improvements; and (5) incentive programs to encourage the use ...


Resources For Marine Shoreline Design, Theresa Mitchell 2017 Washington Department of Fish and Wildlife

Resources For Marine Shoreline Design, Theresa Mitchell

Salish Sea Ecosystem Conference

Shoreline armoring and reducing the use of hard, structural approaches to protecting property is a hot topic across marine communities of North America. As we learn more about the importance of the marine and terrestrial interface (the nearshore zone), we also understand more about how our past practices of hard armoring shorelines can be problematic to the nearshore zone and the ecosystem goods and services it provides. Shifting property owners away from using common hard approaches to erosion protection is difficult to achieve without easy access to information on effective environmentally-friendly alternatives.

The Washington Department of Fish and Wildlife and ...


Armoring On Puget Sound: Progress Towards A Better Baseline, Hugh Shipman, Jennifer Burke, Randy Carman, Kurt Fresh 2017 WA Department of Ecology

Armoring On Puget Sound: Progress Towards A Better Baseline, Hugh Shipman, Jennifer Burke, Randy Carman, Kurt Fresh

Salish Sea Ecosystem Conference

The construction of seawalls and similar structures along Puget Sound’s shoreline impacts geomorphic processes and ecological functions. The extent of shoreline armor has been adopted by the Puget Sound Partnership as a vital sign indicator, is used by local, state, and federal groups as a measure of ecosystem function, and has been employed as a tool for prioritizing restoration actions.

As a result, we recognized the importance of accurately characterizing the extent, character, and distribution of shoreline armor. The objectives of our project were to review existing data sources, assess methodologies, identify gaps in data quality or coverage, and ...


Problem To Progress: Understanding And Improving Permitting For Shoreline Armoring In Kitsap County, Kathlene M. Barnhart 2017 Kitsap County, Washington

Problem To Progress: Understanding And Improving Permitting For Shoreline Armoring In Kitsap County, Kathlene M. Barnhart

Salish Sea Ecosystem Conference

Kitsap County partnered with San Juan County and the Washington Department of Fish and Wildlife to objectively review and assess the effectiveness of existing marine shoreline stabilization permitting programs in achieving a balance between applicant needs and protection of nearshore resources. Utilizing a T.A.C.T. approach (Troubleshooting, Action planning, Course correction and Tracking & monitoring), the agencies worked together to identify gaps and overlap in the permit review and monitoring process, as well as the effectiveness of permit provisions (conditions) through field assessment of recent marine shoreline armoring projects. Actions to correct these internal deficiencies ...


Mapping On The Edge: Shoreline Mapping For Regulation And Voluntary Stewardship, Kate E. Emmings 2017 Islands Trust

Mapping On The Edge: Shoreline Mapping For Regulation And Voluntary Stewardship, Kate E. Emmings

Salish Sea Ecosystem Conference

Nothing generates conversations between landowners and local government like a map! Shoreline mapping is a crucial decision making tool for local governments and regulators. It provides information about appropriate location of shoreline infrastructure, such as docks, and informs landowners about the location of important natural transition areas between the land and the sea. Maps can also provide information that limits the activities of private landowners and as such can cause community conflict if they are inaccurate or unclear. Because mapping can be used to inform regulation, local governments often have different needs than scientists and NGOs, but there is no ...
