Comparison Of Topographic Surveying Techniques In Streams, Sara G. Bangen Utah State University
Comparison Of Topographic Surveying Techniques In Streams, Sara G. Bangen
All Graduate Theses and Dissertations
Fine-scale resolution digital elevation models (DEMs) created from data collected using high precision instruments have become ubiquitous in fluvial geomorphology. They permit a diverse range of spatially explicit analyses including hydraulic modeling, habitat modeling and geomorphic change detection. Yet, the intercomparison of survey technologies across a diverse range of wadeable stream habitats has not yet been examined. Additionally, we lack an understanding regarding the precision of DEMs derived from ground-based surveys conducted by different, and inherently subjective, observers. This thesis addresses current knowledge gaps with the objectives i) to intercompare survey techniques for characterizing instream topography, and ii) to characterize ...
The Effect Of Medetomidine On The Burying Speed Of Corbicula Fluminea, Andrew K. Schmucker '14 Gettysburg College
The Effect Of Medetomidine On The Burying Speed Of Corbicula Fluminea, Andrew K. Schmucker '14
A new anti-fouling drug, medetomidine, was tested to determine if it reduced the burying speed of a freshwater alien-invasive bivalve species, Corbicula fluminea. Corbicula are known to damage underwater structures and must be managed with chemical paints. The burying speeds of Corbicula were measured both before and after exposure to two different concentrations of medetomidine. The burying speed of Corbicula before exposure to a 1x10-6 M medetomidine solution was not significantly different from the burying speed after exposure (t=.55, df=21, p=.588). The burying speed of Corbicula was significantly slower after exposure to a 1x10-5 M ...
Assessment Of Sea Lice Infestations On Wild Fishes Of Cobscook Bay, Alexander Jensen The University of Maine
Assessment Of Sea Lice Infestations On Wild Fishes Of Cobscook Bay, Alexander Jensen
Sea lice are ectoparasitic copepods on fishes and can negatively impact aquaculture operations. Little work on sea lice, specifically Lepeophtheirus salmonis and Caligus elongatus, has occurred in the northwest Atlantic. This project characterized sea lice infestations on wild fishes in Cobscook Bay during 2012. Trawling, seine netting, and fyke netting occurred from March to November. Netting sites were selected to sample the bay’s three regions: Outer, Central, and Inner Bay. Visual examinations of fish were used to identify wild hosts and characterize sea lice life stage abundances, attachment locations, and infection prevalence and intensity. DNA sequencing was used to ...
Recent Mass Mortality Of Strongylocentrotus Purpuratus (Echinodermata: Echinoidea) At Malibu And A Review Of Purple Sea Urchin Kills Elsewhere In California, Gordon Hendler
Bulletin of the Southern California Academy of Sciences
Mass mortalities of intertidal purple sea urchins, Strongylocentrotus purpuratus occurred at Malibu Lagoon State Beach, California, in 2010 and 2011. Both events followed the first heavy rain of the season, and coincided with an illegal breaching of the lagoon. Osmotic shock from low-salinity lagoon water, the likely cause of death, may have acted jointly with stress from exposure during especially low tides. Comparable die-offs of purple sea urchins have occurred at other localities after exposure to brackish water or thermal shock. Annually recurring lagoon ruptures at Malibu, combined with predation by western gulls, can have a profound impact on the ...
Design Of An Underwater Video And Gps Mapping System For The Exploration Of Streambed Aquatic Populations, William Barbour University of Tennessee, Knoxville
Design Of An Underwater Video And Gps Mapping System For The Exploration Of Streambed Aquatic Populations, William Barbour
EURēCA: Exhibition of Undergraduate Research and Creative Achievement
This design project was initiated due to the need for an underwater video mapping system optimized for exploration along the streambed or riverbed and under rocks. Such a system would be used for population mapping of fish and other aquatic species. The system also needed to incorporate global positioning system data with the visual data. The current prototype successfully fulfills the requirements for underwater practicality and visual and GPS data collection. It incorporates a compact waterproof camera with Sony lens, two Fenix high-intensity waterproof flashlights for illumination, a handheld DVR for recording video, and a Garmin 60CSx GPS unit. The ...
Economic Efficiency In Fisheries And Aquaculture, Paul Molyneaux The University of Maine
Economic Efficiency In Fisheries And Aquaculture, Paul Molyneaux
Reflection of the author as a worker looking to make the best use of his time and energy. His innate understanding of the principles of ecological economics followed by exposure to the discipline’s advancing theories leads to a revelation regarding the backwards logic of fisheries and aquaculture policy thus far, and the decline in real seafood production.Along with many others, Molyneaux looks to ecological economics to create a new paradigm for sustainable fisheries.

Ecology And Conservation Of The Montane Forest Avian Community In Northeastern North America, William V. DeLuca University of Massachusetts - Amherst
Ecology And Conservation Of The Montane Forest Avian Community In Northeastern North America, William V. Deluca
Open Access Dissertations
Montane forests provide habitat for unique assemblages of flora and fauna that contribute significantly to a region’s biodiversity. Previous work indicates that montane forest ecosystems are exceedingly vulnerable to a host of anthropogenic stressors including climate change, atmospheric deposition, and recreation, to name a few. Montane forests and other high elevation ecosystems are considered to be among the first and most severely impacted by climate change. It is therefore, imperative to evaluate anthropogenic impacts on montane ecosystems and maintain reliable monitoring methods that are capable of tracking potential shifts in the distribution of species dependent on these systems. I ...
Assessment Of A Rotenone Application Event At Mormon Island West Lake In Central Nebraska, Keith D. Koupal, Brian C. Peterson, Casey W. Schoenebeck University of Nebraska - Lincoln
Assessment Of A Rotenone Application Event At Mormon Island West Lake In Central Nebraska, Keith D. Koupal, Brian C. Peterson, Casey W. Schoenebeck
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
Fisheries managers applied rotenone to Mormon Island West in August of 2010 to renovate a fish community that was hypothesized to be unbalanced (i.e., dominated with gizzard shad and common carp) based on standardized survey results. We estimated species-specific biomass following the lake renovation to provide a baseline biomass estimate for a sand pit lake and to evaluate the effectiveness of standardized sampling gears. Gizzard shad (Dorosoma cepedianum) were abundant in all sampling gears, but mostly stock-size (>175 mm total length) and larger individuals were caught in gill and trap nets and sub-stock (≤175 mm total length) individuals were ...
