Population Assignment Of Entrained Migratory Westslope Cutthroat Trout In North Idaho, Craig D. Wells Jan 2022

Population Assignment Of Entrained Migratory Westslope Cutthroat Trout In North Idaho, Craig D. Wells

EWU Masters Thesis Collection

The Clark Fork-Pend Oreille River basin of northeastern Washington and the Idaho Panhandle historically supported a robust metapopulation of Westslope Cutthroat Trout (WCT) Oncorhynchus clarkii lewisi, a western native salmonid of high cultural and economic value. The construction of impassible hydroelectric dams and smaller in-stream barriers has prevented the return of migratory WCT to spawning tributaries, likely leading to the fragmentation of this metapopulation over the last 100 years. One such impassible barrier is Albeni Falls Dam near Newport, Washington. Completed without fish passage capabilities in 1955, Albeni Falls Dam has been of interest as a site for restoring fish …

Feed Conditioning Effects On Enzymes, Amino Acids, And Subsequent Broiler Performance, Elizabeth Ann Lynch Jan 2022

Feed Conditioning Effects On Enzymes, Amino Acids, And Subsequent Broiler Performance, Elizabeth Ann Lynch

Graduate Theses, Dissertations, and Problem Reports (ETD)

There are many things that can be done to improve broiler performance including, but not limited to, pelleting, proper Lys inclusion, and exogenous enzyme supplementation. Pelleting has the ability to improve feed form, reduce wastage, improve bird performance metrics, and decrease pathogens within the feed. Pathogen reduction can be further reduced by hygienic pelleting practices which include an increase in temperature or retention time within a conditioner or hygieniser. However, hygienic pelleting can degrade valuable AA and enzymes (more specifically for the current thesis research Lys and phytase) and make them unavailable to the animal. Supplementing Lys to account for …

Genetic Analysis And Telemetry Study Of Migration Habits Of The Endangered Atlantic Sturgeon, Cassia Marie Busch Jan 2022

Genetic Analysis And Telemetry Study Of Migration Habits Of The Endangered Atlantic Sturgeon, Cassia Marie Busch

Graduate Theses, Dissertations, and Problem Reports (ETD)

Atlantic sturgeon are a long-lived anadromous fish that ranged from Labrador, Canada to Florida, US. Due to overharvest in the late 1800’s and 1900’s, Atlantic sturgeon populations across the coast experienced a dramatic population crash. Recovery of this species has faced challenges due to anthropogenic threats, such as vessel strikes, bycatch, and habitat degradation. In 2012, Atlantic sturgeon were added to the United States Endangered Species Act (ESA). Under the ESA, populations were listed as five distinct population segments (DPS), reflecting their geographic arrangement and genetic structure: Gulf of Maine DPS (threatened), New York Bight DPS (endangered), Chesapeake DPS (endangered), …

Small Mammal Communities Of Restored And Natural Wetlands In West Virginia, Krista Noe Jan 2022

Small Mammal Communities Of Restored And Natural Wetlands In West Virginia, Krista Noe

Graduate Theses, Dissertations, and Problem Reports (ETD)

Wetland restoration is commonly practiced as part of conservation programs or wetland mitigation, which attempts to offset human-created losses of natural wetlands. However, because of the intrinsic and human-derived value of wetlands, it is critical to determine whether these wetlands truly act similarly to natural wetlands. One role of wetlands is to provide habitat for a diverse array of wildlife species. Small mammals are often overlooked taxa in wetland restoration efforts. However, they are essential to the wetland system because they influence vegetation and are prey for higher trophic level wildlife. I discuss considerations of restored wetlands, wildlife responses to …

Subsurface Eddy Facilitates Retention Of Simulated Diel Vertical Migrators In A Biological Hotspot, K. Hudson, M. J. Oliver, J. Kohut, J. H. Cohen, Michael S. Dinniman, John M. Klinck, C. S. Reiss, G. R. Cutter, H. Statscewich, K. S. Bernard, W. Fraser

OES Faculty Publications

Diel vertical migration (DVM) is common in zooplankton populations worldwide. Every day, zooplankton leave the productive surface ocean and migrate to deepwater to avoid visual predators and return to the surface at night to feed. This behavior may also help retain migrating zooplankton in biological hotspots. Compared to fast and variable surface currents, deep ocean currents are sluggish, and can be more consistent. The time spent in the subsurface layer is driven by day length and the depth of the surface mixed layer. A subsurface, recirculating eddy has recently been described in Palmer Deep Canyon (PDC), a submarine canyon in …

Temporal Stability Of Seagrass Extent, Leaf Area, And Carbon Storage In St. Joseph Bay, Florida: A Semi-Automated Remote Sensing Analysis, Marie Cindy Lebrasse, Blake A. Schaeffer, Megan M. Coffer, Peter J. Whitman, Richard C. Zimmerman, Victoria J. Hill, Kazi A. Islam, Jiang Li, Christopher L. Osburn

OES Faculty Publications

Seagrasses are globally recognized for their contribution to blue carbon sequestration. However, accurate quantification of their carbon storage capacity remains uncertain due, in part, to an incomplete inventory of global seagrass extent and assessment of its temporal variability. Furthermore, seagrasses are undergoing significant decline globally, which highlights the urgent need to develop change detection techniques applicable to both the scale of loss and the spatial complexity of coastal environments. This study applied a deep learning algorithm to a 30-year time series of Landsat 5 through 8 imagery to quantify seagrass extent, leaf area index (LAI), and belowground organic carbon (BGC) …

A Subsurface Eddy Associated With A Submarine Canyon Increases Availability And Delivery Of Simulated Antarctic Krill To Penguin Foraging Regions, K. Hudson, M. J. Oliver, J. Kohut, Michael S. Dinniman, John M. Klinck, M. A. Cimino, K. S. Bernard, H. Statscewich, W. Fraser

OES Faculty Publications

The distribution of marine zooplankton depends on both ocean currents and swimming behavior. Many zooplankton perform diel vertical migration (DVM) between the surface and subsurface, which can have different current regimes. If concentration mechanisms, such as fronts or eddies, are present in the subsurface, they may impact zooplankton near-surface distributions when they migrate to near-surface waters. A subsurface, retentive eddy within Palmer Deep Canyon (PDC), a submarine canyon along the West Antarctic Peninsula (WAP), retains diurnal vertically migrating zooplankton in previous model simulations. Here, we tested the hypothesis that the presence of the PDC and its associated subsurface eddy increases …

Determination Of Plant-Specific Retrotransposons In Chicken, Levent Mercan, Ci̇hat Erdem Bülbül, Fati̇h Bi̇lgi̇, Sevgi̇ Marakli

Turkish Journal of Veterinary & Animal Sciences

Mobile genetic elements are also known as transposons, comprising a significant proportion of plant and animal genomes. Retrotransposons, a class of transposons, move copy and paste mechanism and, therefore, cause genome obesity. Moreover, the transferability of retrotransposons within and between different kingdoms has provided valuable information for evolutionary relationships in addition to detailed knowledge about genomes. We identified barley-specific retrotransposons (Nikita and Sukkula) and determined polymorphism ratios of these retrotransposons in a chicken genome for the first time to gain new insights for retrotransposons found in different genomes. Transposon sequences belonging to chicken and barley genomes were also investigated to …

A Game Theoretic Approach To Design Mating Programs For Livestock, Ebru Ergüneş Berki̇n, Hasan Önder, Özgür Hakan Aydoğmuş

Turkish Journal of Veterinary & Animal Sciences

In this study, we proposed a new game theoretic method to design a mating program. The index and game theoretic methods were applied with calculated breeding values using pedigree on two different data sets whose economic traits consist of negative (milk yield and fat percentage) and positive (birth and weaning weight) genetic correlated data. For the negative genetic correlated data set, even if total expected benefits were equal for two methods, mating programs were changed, and the coefficient of variation obtained using the game theoretic method was smaller than that of the index method. This result showed that the expected …
