The Impacts Of Climate Change On The Gulf Of Maine Northern Shrimp (Pandalus Borealis) Distribution, Reproduction, And Life, Hsiao-Yun Chang

Electronic Theses and Dissertations

The Gulf of Maine northern shrimp (Pandalus borealis) once supported a significant winter fishery for the Gulf of Maine (GOM). Although the shrimp fishery is not comparable to the lobster business, it provided fishermen and many coastal communities jobs and incomes in winters after lobster seasons. However, a moratorium has been put on the shrimp fishery since 2014 due to record low population abundance and perceived recruitment failures. The recruitment failures have been correlated with warming water temperatures over the past decade. The GOM has been recognized as experiencing rapid warming as a result of global climate change. …

Contributions To The Knowledge Of Water Bugs In Mindoro Island, Philippines, With A Species Checklist Of Nepomorpha And Gerromorpha (Insecta, Hemiptera, Heteroptera), Arthien Lovell Pelingen, Herbert Zettel, Clister V. Pangantihon, Kyra Mari Dominique Aldaba, Earl Kevin Fatallo, Jemillie Madonna De Leon, Hendrik Freitag

Biology Faculty Publications

This survey aims to provide an updated species checklist of aquatic and semi-aquatic bugs in the intra-Philippine biogeographic Region of Mindoro. An assessment survey of water bugs (Hemiptera, Heteroptera) was conducted mostly by manual collection in selected areas of Oriental Mindoro from 2017 to 2018, in which some of the collecting activities were undertaken by graduate students of Ateneo de Manila University. Twenty-nine aquatic and semi-aquatic heteropteran species were documented and some are known island-endemic species or subspecies, including Enithares martini mindoroensis Nieser & Zettel, 1999, Hydrotrephes stereoides mindoroensis Zettel, 2003, Aphelocheirus freitagi Zettel & Pangantihon, 2010, Rhagovelia mindoroensis Zettel, …

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 …

Distribution And Status Of The Northern Leopard Frog, Rana Pipiens, In West Virginia, Amanda Nicole Spriggs

Theses, Dissertations and Capstones

The Northern Leopard Frog, Rana pipiens, is listed as a species of concern by the West Virginia Division of Natural Resources. Because this species is uncommon in West Virginia, information is needed to understand its distribution and conservation needs. I surveyed 14 historic R. pipiens locations and 70 Wildlife Management Areas throughout West Virginia beginning in March 2008. Rana pipiens was found in four locations; Greenbottom Wildlife Management Area was confirmed through both auditory and visual surveys and the rest were confirmed through visual observations. Besides Greenbottom Wildlife Management Area, all other sites were confirmed by the presence of a …

A Study On The Population Size And Natural History Of The Eastern Six‐Lined Racerunner, Aspidoscelis Sexlineata, In West Virginia, With Notes On Other Lizard Species, Emmy Johnson

Theses, Dissertations and Capstones

Species will expand ranges through natural or human‐alterations. Such an occurrence has happened in West Virginia with Eastern Six‐lined Racerunner, Aspidsocelis sexlineata, a species that has been found to thrive in areas of high disturbance from humans. While found abundantly in other states, they are thought to occur only in the eastern panhandle of West Virginia (Morgan County) where they are believed to have come from Maryland via a railroad bridge. Without the bridge, the Potomac River forms a natural barrier between these two states. The objectives of my study were to determine the population size and natural history …

Habitat Selection By Lacustrine Rainbow Trout Within Gradients Of Temperature, Oxygen, And Food Availability, Chris Luecke, D. Teuscher

Watershed Sciences Faculty Publications

Rainbow trout (Oncorhynchus mykiss [Walbaum]) in Castle Lake, California were concentrated at certain depths during day and evening hours. A fish bioenergetics simulation model based on vertical gradients of temperature, oxygen concentration, and food availability indicated that rainbow trout selected habitats that maximized growth rate. In 1 of the 2 years of study, a strong pattern of diel vertical migration of rainbow trout was evident and was associated with vertical migrations of daphnids in the lake. The simulation model correctly predicted the occurrence and magnitude of fish migration. During the day some trout resided at depths with little potential for …

The Influence Of Redd Distribution And Microhabitat Availability On The Distribution And Abundance Of Young-Of-The-Year Trout In The Green River, Utah, Michael J. Buntjer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Redd distribution, redd density, and physical habitat were used to explain the distribution and abundance of young-of-the-year (YOY) brown trout (Salmo trutta) and rainbow trout (Oncorhynchus mykiss) in the Green River, Utah. The importance of variables at both a microhabitat and macrohabitat scale were assessed using stepwise regression analysis. Availability of cover (rock and vegetation) and proximity to spawning sites were the most important variables used to explain the distribution and abundance of YOY brown trout and rainbow trout. In addition, YOY brown trout and rainbow trout occupied specific microhabitats and showed patterns of use for …

Transport Of Bivalve Larvae In James River, Virginia, J. D. Andrews

VIMS Articles

For nearly 100 years, the James River has been the primary source of seed oysters for Virginia. A disease caused by Minchinia nelsoni (MSX) killed most oysters in high-salinity waters in the lower river in 1959 and 1960, and planting has not been resumed in these areas (Andrews 1983). Large populations of oysters on Hampton Bar and near the mouth of the river which served as broodstocks were destroyed. After 1960, setting declined drastically in regularity and intensity to about one tenth of that which occurred in the 1950's. Setting patterns suggest two types of seed areas in Chesapeake Bay: …

Food And Distribution Of Underyearling Brook And Rainbow Trout In Castle Lake, California, Wayne A. Wurtsbaugh, R. Brocksen, C. Goldman

Watershed Sciences Faculty Publications

A difference was found in the summer distribution of underyearling brook trout, Salvelinus fontinalis (Mitchill), and planted rainbow trout, Salmo gairdneri Richardson, in Castle Lake, California. Brook trout underyearlings oriented to the bottom and were found primarily in shallow water on the eastern shore of the lake near springs. The rainbow trout underyearlings were more pelagic and were found in the littoral areas along the entire shoreline. Gravimetrically, the food eaten during the summer by brook trout underyearlings was 13% terrestrial, 11% limnetic, and 76% benthic. Rainbow trout ate 15% terrestrial, 15% limnetic, and 70% benthic food. In summer, rainbow …
