Trophish: Building A Global Database Of Freshwater Trophic Interactions, Jacob M. Ridgway

Honors Thesis

Freshwater management and research frequently use the trophic data of freshwater fishes. Despite this fact, it is difficult to perform a simple search of dietary information for any one fish species. FishBase represents, to our knowledge, the largest compilation of freshwater dietary information to date. However, it excludes a large portion of the ecological literature due to its development taking place prior to the creation of most modern scientific search engines. Our project (TroPhish) is building upon FishBase by digitizing approximately 130 years of data from the fish predation literature. Data from the primary and grey (e.g. theses, dissertations, reports) …

Assessing Populations Of Eastern Brook Trout (Salvelinus Fontinalis) Above And Below Waterfalls In Mountain Streams Of Virginia, Hannah Eisemann Macmillan

Masters Theses, 2010-2019

Anthropogenically driven factors, such as increasing temperature and sediment in valley streams, acidification of mountain streams, and the introduction of non-native trout, are restricting habitat suitable for healthy populations of eastern brook trout (Salvelinus fontinalis) throughout their native Appalachian range. Brook trout are important as predators of insects in mountain streams and as a favorite of anglers. It is crucial that remaining populations in sustainable habitats be identified and preserved. Waterfalls are geologic knickpoints preventing base-level lowering that create unique, stable landscapes above them, which may alleviate the temperature-productivity/acidity “habitat squeeze” for populations of brook trout and could …

Distribution And Habitat Use Of Benthic Fishes In The Lower Kanawha River, West Virginia, Nathaniel V. Owens

Graduate Theses, Dissertations, and Problem Reports

The Kanawha River in West Virginia is a historically diverse system in terms of ichthyofauna although, like many other large rivers, it has been subjected to a suite of anthropomorphic perturbations. These include this system being modified to allow the passage of commercial vessels for industry thus altering flow regimes, increased sedimentation, water depth, and channelization, and decreased interactions with its floodplain. Additionally, the fishes of this system have suffered from deleterious historical water quality issues caused by intensive timber operations, mining, and industrial waste. Post Clean Air Act, Clean Water Act, and Surface Mining Control and Reclamation Act water …

Effects Of Wave Action On The Structure Of Fish Assemblages Across An Exposure Gradient, Lauren Liddon

Master's Theses

Disturbance affects the function and diversity of ecosystems. Increased wave exposure to salt marsh can disturb sediments and cause a loss of habitat. The purpose of this study was to explore the effects of increased wave exposure on diversity, abundance, and functional ecology of estuarine fishes. If increased wave exposure is acting as a disturbance to these habitats, ecological theory (Intermediate Disturbance Hypothesis) predicts that diversity will peak at intermediate frequencies and intensities of disturbance. Fish were sampled from 10 sites monthly for 6 years. The sites were assigned to different exposure categories (Open, Intermediate, and Sheltered) using an exposure …

Flight of the Freshwater Fish

The Hudson River provides for millions of people as a path for commercial and private transportation, a source of food and energy, and perhaps most importantly for many living in the tri-state area as a destination for recreation and relaxation. The most overlooked feature of the river is how the wildlife shows clear signs of a changing climate and rapid environmental response to the impacts of global warming on the river.

Entire populations of fish species in the lower Hudson have been forced to leave the river …

Summer 2015 Gis Analyst Internship At The Connecticut Department Of Energy & Environmental Protection, Old Lyme, Connecticut, Stuart R. Deland

International Development, Community and Environment (IDCE)

I worked as the Geographic Information Systems (GIS) Internee for the Connecticut Department of Energy & Environmental Protection (CT DEEP) from May 18, 2015 through August 14th of the same year. I was stationed at the Old Lyme Field office and worked under the direct supervision of Deb Pacileo, my boss and GIS analyst for CT DEEP. My function in the agency was similar to my supervisor's as I had no single project that dominated my time, but was given a multitude of projects to create, edit, oversee, and produce. Some of these project included editing python scripts of former …
