Analysis Of An Agent-Based Model For Predicting The Behavior Of Bighead Carp (Hypophthalmichthys Nobilis) Under The Influence Of Acoustic Deterrence, Craig Garzella, Joseph Gaudy, Karl R. B. Schmitt, Arezu Mansuri Feb 2020

Analysis Of An Agent-Based Model For Predicting The Behavior Of Bighead Carp (Hypophthalmichthys Nobilis) Under The Influence Of Acoustic Deterrence, Craig Garzella, Joseph Gaudy, Karl R. B. Schmitt, Arezu Mansuri

Spora: A Journal of Biomathematics

Bighead carp (Hypophthalmichthys nobilis) are an invasive, voracious, highly fecund species threatening the ecological integrity of the Great Lakes. This agent-based model and analysis explore bighead carp behavior in response to acoustic deterrence in an effort to discover properties that increase likelihood of deterrence system failure. Results indicate the most significant (p < 0.05) influences on barrier failure are the quantity of detritus and plankton behind the barrier, total number of bighead carp successfully deterred by the barrier, and number of native fishes freely moving throughout the simulation. Quantity of resources behind the barrier influence bighead carp to penetrate when populations are resource deprived. When native fish populations are low, an accumulation of phytoplankton can occur, increasing the likelihood of an algal bloom occurrence. Findings of this simulation suggest successful implementation with proper maintenance of an acoustic deterrence system has potential of abating the threat of bighead carp on ecological integrity of the Great Lakes.

Individual Variation In Winter Brook Trout (Salvelinus Fontinalis) Movement In A Small Northern Michigan Stream, Benjamin Bejcek Feb 2020

Individual Variation In Winter Brook Trout (Salvelinus Fontinalis) Movement In A Small Northern Michigan Stream, Benjamin Bejcek

All NMU Master's Theses

Winter is a time of year of low temperatures and limited food availability. Brook trout (Salvelinus fontinalis) survival in winter is dependent on several factors including their condition after spawning in the fall and possibly their behavior in winter. Ice that forms during winter can potentially aid in survival by decreasing predation risk, decreasing stress, and acting as a thermal refuge. The emphasis of this project was to evaluate the relationship between movement patterns of brook trout and winter ice distribution. In the fall of 2017 and again in the fall of 2018, brook trout in a northern Michigan stream …

Catfish Population Characteristics Among River Segments With Altered Fluvial Geomorphic Conditions In The Missouri River, Nebraska, Usa, Martin J. Hamel, Jonathan J. Spurgeon, Mark A. Pegg Jan 2020

Catfish Population Characteristics Among River Segments With Altered Fluvial Geomorphic Conditions In The Missouri River, Nebraska, Usa, Martin J. Hamel, Jonathan J. Spurgeon, Mark A. Pegg

School of Natural Resources: Faculty Publications

Alteration of river systems around the world has created novel environments that have been fragmented, homogenized, or transformed from their natural state, thus posing challenges for understanding how fish populations function. The Missouri River has undergone significant alteration through reservoir construction and channelization. Channel Catfish Ictalurus punctatus and Flathead Catfish Pylodictis olivaris both reside in various fragmented sections of the river, and there is a substantial gap in knowledge of how catfishes synchronously function in this modified system. From 2009 to 2018, we assessed catfishes with baited hoop nets and low-frequency electrofishing among four different areas: upper and lower unchannelized …

Laboratory Investigation On The Effects Of Conductivity On The Sensitive Early Life Stages Of Fishes From The Appalachian Region, Logan Ryan Beach Jan 2020

Laboratory Investigation On The Effects Of Conductivity On The Sensitive Early Life Stages Of Fishes From The Appalachian Region, Logan Ryan Beach

Theses, Dissertations and Capstones

While it is known there is a link between land disturbance and elevations in ionic constituents in streams, the relationship between elevated conductivity and aquatic taxa impairment is harder to define. Multiple field studies demonstrating correlations between conductivity and fish or benthic macroinvertebrate communities have not described the mechanisms of impairment and impairment has not been demonstrated with traditional toxicity testing. In an effort to explore more sensitive sub-lethal endpoints for evaluation of instream effects of mining effluent, chronic toxicity testing was conducted on eggs and early life stages of trout species and the fathead minnow, utilizing a simulated mining …

Eastern Diamondback Rattlesnake (Crotalus Adamanteus) Ambush Site Selection In Coastal Saltwater Marshes, Emily Rebecca Mausteller Jan 2020

Eastern Diamondback Rattlesnake (Crotalus Adamanteus) Ambush Site Selection In Coastal Saltwater Marshes, Emily Rebecca Mausteller

Theses, Dissertations and Capstones

The eastern diamondback rattlesnake (Crotalus adamanteus; EDB) is a species of conservation concern associated with the imperiled longleaf pine-grassland ecosystem. The longleaf pine ecosystem is characterized by an open canopy and rich ground cover. Researchers have speculated that the vegetation structure of salt marshes may serve as a surrogate habitat for longleaf pine savannas. Although these marshes have little topography, they provide a heterogeneous landscape with patches of mud flats, sandy hard marsh along upper tidal areas, and salt marsh hummocks throughout. I used radio telemetry to monitor free-ranging EDBs on a South Carolina sea island. The goal of my …

The Effects Of Light Level And Temperature On Freshwater Microbial Biomass, Production, Enzyme Activity, And Community Composition, Joel Bonney Jan 2020

The Effects Of Light Level And Temperature On Freshwater Microbial Biomass, Production, Enzyme Activity, And Community Composition, Joel Bonney

Master's Theses and Doctoral Dissertations

Algae can stimulate the production of heterotrophic microbes in periphyton communities, but the synergistic effects of light and temperature on this phenomenon are not well understood and have implications on carbon cycling and energy flow. We employed recirculating mesocosms held at different temperatures and light levels and filled with Typha litter and attached microbes to assess these effects. Heterotrophic microbial production was greater in the presence of light, as were some periphytic enzyme activities. Few response variables increased in a near-linear fashion with ascending temperature, suggesting different temperature optima. The strength of heterotrophic microbial production responses to algal photosynthesis did …

Size And Density Of Upside-Down Jellyfish, Cassiopea Sp., And Their Impact On Benthic Fluxes In A Caribbean Lagoon, Chester B. Zarnoch, Noshin Hossain, Erika Fusco, Mary Alldred, Timothy J. Hoellein, Sophia Perdikaris Jan 2020

Size And Density Of Upside-Down Jellyfish, Cassiopea Sp., And Their Impact On Benthic Fluxes In A Caribbean Lagoon, Chester B. Zarnoch, Noshin Hossain, Erika Fusco, Mary Alldred, Timothy J. Hoellein, Sophia Perdikaris

School of Global Integrative Studies: Faculty Publications

Anthropogenic disturbances may be increasing jellyfish populations globally. Epibenthic jellyfish are ideal organisms for studying this phenomenon due to their sessile lifestyle, broad geographic distribution, and prevalence in near-shore coastal environments. There are few studies, however, that have documented epibenthic jellyfish abundance and measured their impact on ecological processes in tropical ecosystems. In this study, the density and size of the upside-down jellyfish (Cassiopea spp.) were measured in Codrington Lagoon, Barbuda. A sediment core incubation study, with and without Cassiopea, also was performed to determine their impact on benthic oxygen and nutrient fluxes. Densities of Cassiopea were 24–168 …

Use Of Otolith Chemistry To Assess Recruitment And Habitat Use Of A White Bass Fishery In A Nebraska Reservoir, Matthew A. Perrion, Mark A. Kaemingk, Keith D. Koupal, Casey W. Schoenebeck, Nate A. Bickford Jan 2020

Use Of Otolith Chemistry To Assess Recruitment And Habitat Use Of A White Bass Fishery In A Nebraska Reservoir, Matthew A. Perrion, Mark A. Kaemingk, Keith D. Koupal, Casey W. Schoenebeck, Nate A. Bickford

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Managing fisheries that exhibit variable annual recruitment is challenging, and maintenance stockings are often prescribed to minimize interannual population variation. Maintenance stockings are costly and may not be necessary if sufficient natural recruitment is occurring. Therefore, developing tools and techniques that can collectively assess hatching origin and subsequent habitat use of individuals would be valuable. Herein, we aimed to assess the efficacy of otolith chemistry techniques to (1) determine whether there was evidence of natural recruitment within an annually stocked white bass population and (2) examine the potential to describe spatial reservoir use of these age-0 fish. A sample of …

Using Northern Pike And Yellow Perch To Attempt A Trophic Cascade, Bryan Sea

Journal of Earth and Life Science

In the midwestern USA, water clarity has decreased in shallow lakes as a result of large populations of Fathead Minnow Pimephales promelas and agriculture that impact the life that depend on shallow habitats, such as waterfowl, fish, and aquatic plants. Northern Pike Esox lucius and Yellow Perch Perca flavescens were stocked in a few lakes in attempt to create a tropic cascade and reduce populations of nuisance Fathead Minnows. Northern Pike were stocked as fry and Yellow Perch were stocked as adults either pre-spawn or post-spawn. Lake managers hypothesized adult Yellow Perch would spawn and the age-0 Perch would feed …

Squids Use Multiple Escape Jet Patterns Throughout Ontogeny, Carly A. York, Ian K. Bartol, Paul S. Krueger, Joseph T. Thompson Jan 2020

Squids Use Multiple Escape Jet Patterns Throughout Ontogeny, Carly A. York, Ian K. Bartol, Paul S. Krueger, Joseph T. Thompson

Biological Sciences Faculty Publications

Throughout their lives, squids are both predators and prey for a multitude of animals, many of which are at the top of ocean food webs, making them an integral component of the trophic structure of marine ecosystems. The escape jet, which is produced by the rapid expulsion of water from the mantle cavity through a funnel, is central to a cephalopod's ability to avoid predation throughout its life. Although squid undergo morphological and behavioral changes and experience remarkably different Reynolds number regimes throughout their development, little is known about the dynamics and propulsive efficiency of escape jets throughout ontogeny. We …

Direct And Indirect Effects Of Sex Steroids On Gonadotrope Cell Plasticity In The Teleost Fish Pituitary, Romain Fontaine, Muhammad Rahmad Royan, Kristine Von Krogh, Finn-Arne Weltzien, Dianne M. Baker Jan 2020

Direct And Indirect Effects Of Sex Steroids On Gonadotrope Cell Plasticity In The Teleost Fish Pituitary, Romain Fontaine, Muhammad Rahmad Royan, Kristine Von Krogh, Finn-Arne Weltzien, Dianne M. Baker

Biological Sciences Research

The pituitary gland controls many important physiological processes in vertebrates, including growth, homeostasis, and reproduction. As in mammals, the teleost pituitary exhibits a high degree of plasticity. This plasticity permits changes in hormone production and secretion necessary to meet the fluctuating demands over the life of an animal. Pituitary plasticity is achieved at both cellular and population levels. At the cellular level, hormone synthesis and release can be regulated via changes in cell composition to modulate both sensitivity and response to different signals. At the cell population level, the number of cells producing a given hormone can change due to …

Cold-Water Prey Fish Monitoring And Ecology In Lake Oahe, Nicholas B. Kludt Jan 2020

Cold-Water Prey Fish Monitoring And Ecology In Lake Oahe, Nicholas B. Kludt

Electronic Theses and Dissertations

In Lake Oahe, a large mainstem Missouri river reservoir that spans 375 river kilometers in central North and South Dakota, naturalized Rainbow Smelt are the primary forage species for a regionally important Walleye Sander vitreus fishery. Walleye condition in Lake Oahe is highly correlated to Rainbow Smelt relative abundance through time, the latter species being typified by erratic abundance trends since accidental introduction in 1971. Cisco Coregonus artedii were introduced in the early 1990s to augment the cold-water prey base. We evaluated Lake Oahe cold-water prey base monitoring and dynamics through: 1.) a comparison of two hydroacoustic survey designs, 2.) …

Distribution, Density, Movement, And Support For Management Of Mountain Sucker, Pantosteus Jordani, In The Black Hills Of South Dakota, Seth J. Fopma Jan 2020

Distribution, Density, Movement, And Support For Management Of Mountain Sucker, Pantosteus Jordani, In The Black Hills Of South Dakota, Seth J. Fopma

Electronic Theses and Dissertations

Mountain Sucker, Pantosteus jordani, is a cold-water species native to the Intermountain West. Fringe populations of Mountain Sucker have experienced declines in recent decades. The population of Mountain Sucker found in the Black Hills of South Dakota represents the eastern fringe of the species’ native range. Recognized as both an indicator of biologic health and as a species of greatest conservation need in South Dakota, recent studies have suggested significant declines in both distribution and abundance. Despite the recent study of Mountain Sucker in the region, increased understanding of Mountain Sucker ecology is needed to effectively manage for the conservation …

Influence Of Mink Predation On Brown Trout Survival And Size-Structure In Rapid Creek, South Dakota, Austin Galinat Jan 2020

Influence Of Mink Predation On Brown Trout Survival And Size-Structure In Rapid Creek, South Dakota, Austin Galinat

Electronic Theses and Dissertations

I compared movement, home range, habitat selection, and mortality among radio-tagged Brown Trout (Salmo trutta) at an American Mink (Neovison vison)-removal site, improved habitat site, and an undisturbed stream site in Rapid Creek, South Dakota. I observed high, post-surgery (> 26 days) survival rate (90%) of radio tagged Brown Trout. Average gross movement of Brown Trout was greater at the improved habitat site (127 m) compared to the mink removal (31 m) site, while average home range size (i.e., stream distance) among all three sites was not significantly different indicating strong site fidelity (125 to 200 m). Brown Trout movements …

Modification Of Plant Proteins And Their Potential Application As Fish Meal Replacements In Rainbow Trout Oncorhynchus Mykiss Feeds, Miran Jaza Hama Salh Jan 2020

Modification Of Plant Proteins And Their Potential Application As Fish Meal Replacements In Rainbow Trout Oncorhynchus Mykiss Feeds, Miran Jaza Hama Salh

Electronic Theses and Dissertations

Soybean meals (SBM) and its by-products are the most common plant feedstuffs that are used in feeds for a variety of fish species of fish over the last three decades due to high protein levels and good amino acid profile, in comparison with other plant protein sources. In the last two decades the production of soybean was around zero metric tons (Index, 2020). Barley is another plant protein that has been tested in some species diets. While barley is used in many areas such as brewing industry, animal feeding, human consumption, it is mainly used for animal feeding in Kurdistan. …

Estimates Of Red Drum Mortality Via Acoustic Telemetry, T. Reid Nelson, Sean P. Powers Jan 2020

Estimates Of Red Drum Mortality Via Acoustic Telemetry, T. Reid Nelson, Sean P. Powers

University Faculty and Staff Publications

Subadult (age < 3) Red Drum Sciaenops ocellatus support a valuable recreational fishery, and mortality estimates for young Red Drum are needed for proper management. To obtain these estimates, age-1 and age-2 Red Drum were implanted with acoustic transmitters and external Floy tags in two coastal Alabama rivers (Fowl and Dog rivers). Fates of tagged fish were inferred from stationary receiver detections and active relocations over 1 year. These fates were used in a Bayesian multistate model to estimate instantaneous monthly and annual mortality and emigration rates for each river and overall from both rivers. Instantaneous monthly fishing mortality (F) ranged from 0.001 to 0.112 (annual F = 0.414) in Dog River, from 0.001 to 0.126 in Fowl River (annual F = 0.309), and was 0.001–0.054 (annual F = 0.337) overall. Instantaneous monthly natural mortality (M) ranged from 0.001 to 0.002 (annual M= 0.069) in Dog River, from 0.001 to 0.036 (annual M= 0.178) in Fowl River, and from 0.001 to 0.017 (annual M= 0.090) overall. The overall annual estimate of instantaneous total mortality (Z) was 0.435. The median escapement percentage was estimated at 36.3% (95% posterior credible interval = 19.5–56.0%) using M and Z from the overall model. Unfortunately, the error on this estimate was large and inconclusive as to whether the 30% escapement goal for juvenile Red Drum to the adult population from Dog and Fowl rivers is being met. Monthly residency estimates were typically greater than 0.90, and overall annual residency was estimated at 0.716. Fishing mortality estimates from the current study are higher than recent catch curve estimates that did not include young Red Drum. These results demonstrate that young Red Drum need to be accounted for when generating mortality estimates and provide needed data for the Red Drum recreational fishery.

Habitat Associations And Co-Occurrence Patterns Of Two Estuarine-Dependent Predatory Fishes, Mariah C. Livernois, Sean P. Powers, Mark A. Albins, John F. Mareska Jan 2020

Habitat Associations And Co-Occurrence Patterns Of Two Estuarine-Dependent Predatory Fishes, Mariah C. Livernois, Sean P. Powers, Mark A. Albins, John F. Mareska

University Faculty and Staff Publications

Estuarine-dependent fishes experience a wide range of environmental conditions, and most species exhibit distinct associations with particular habitats. However, similar species or multiple conspecifics often overlap spatiotemporally, which can result in ecological interactions that have consequences for behaviors that can shape the structure and function of ecosystems. We used a long-term gill-net data set (2001–2015) to investigate the habitat associations and cooccurrence patterns of two estuarine-dependent predatory fishes, Red Drum Sciaenops ocellatus and Spotted Seatrout Cynoscion nebulosus, in coastal Alabama, USA. Both species were associated with similar environmental conditions, primarily low dissolved oxygen and low salinity, especially when temperature was …

Mitogenome Of Northern Long-Eared Bat, Sarah Gaughan, Kevin L. Pope, Jeremy A. White, Cliff Lemen, Patricia Freeman Jan 2020

Mitogenome Of Northern Long-Eared Bat, Sarah Gaughan, Kevin L. Pope, Jeremy A. White, Cliff Lemen, Patricia Freeman

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

The complete mitogenome of the northern long-eared bat (Myotis septentrionalis) was determined to be 17,362 bp and contained 22 tRNA genes, 2 rRNA genes and one control region. The whole genome base composition was 33.8% GC. Phylogenetic analysis suggests that M. septentrionalis be positioned next to M. auriculus in the Nearctic subclade of the Myotis genus. This complete mitochondrial genome provides essential molecular markers for resolving phylogeny and future conservation efforts.

Use And Expenditures On Public Access Hunting Lands, Lyndsie S. Wszola, Lutz F. Gruber, Erica F. Stuber, Lindsey N. Messinger, Christopher J. Chizinski, Joseph J. Fontaine

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

The recreational and economic benefits of hunting on traditional permanent public lands are well-established. Increasingly popular “open fields” hunting access programs temporarily open private lands to public hunting through public-private partnerships. Open fields programs have the potential to create public hunting opportunities and economic development in rural communities, but the extent to which open fields programs compare to traditional public lands at providing benefits to hunters and rural communities has not yet been evaluated. We compared hunter use and expenditures on open fields lands and traditional public lands in Nebraska, USA. We used Convolution Likelihood Ecological Abundance Regression, a novel …
