Wildlife Carcass Disposal, Stephen M. Vantassel, Mark A. King
Wildlife Carcass Disposal, Stephen M. Vantassel, Mark A. King
Wildlife Damage Management Technical Series
Many wildlife management situations require the disposal of animal carcasses. These can include the lethal removal of wildlife to resolve damage or conflicts, as well as clean-up after mortalities caused by vehicle collisions, disease, oil spills (Figure 1) or other natural disasters. Carcasses must be disposed of properly to protect public sensitivities, the environment, and public health. Improper disposal of carcasses can result in public outrage, site contamination, injury to animals and people, and the attraction of other animals that may lead to wildlife damage issues. Concern over ground water contamination and disease transmission from improper carcass disposal has resulted …

All Faculty Scholarship for the College of the Sciences
Objectives
Direct comparative work in morphology and growth on widely dispersed wild primate taxa is rarely accomplished, yet critical to understanding ecogeographic variation, plastic local variation in response to human impacts, and variation in patterns of growth and sexual dimorphism. We investigated population variation in morphology and growth in response to geographic variables (i.e., latitude, altitude), climatic variables (i.e., temperature and rainfall), and human impacts in the vervet monkey (Chlorocebus spp.).
Methods
We trapped over 1,600 wild vervets from across Sub‐Saharan Africa and the Caribbean, and compared measurements of body mass, body length, and relative thigh, leg, and foot …

Fisheries Bycatch Risk To Marine Megafauna Is Intensified In Lagrangian Coherent Structures, Kylie L. Scales, Elliot L. Hazen, Michael G. Jacox, Frederic Castruccio, Sara M. Maxwell, Rebecca L. Lewison, Steven J. Bograd
Biological Sciences Faculty Publications
Incidental catch of nontarget species (bycatch) is a major barrier to ecological and economic sustainability in marine capture fisheries. Key to mitigating bycatch is an understanding of the habitat requirements of target and nontarget species and the influence of heterogeneity and variability in the dynamic marine environment. While patterns of overlap among marine capture fisheries and habitats of a taxonomically diverse range of marine vertebrates have been reported, a mechanistic understanding of the real-time physical drivers of bycatch events is lacking. Moving from describing patterns toward understanding processes, we apply a Lagrangian analysis to a high-resolution ocean model output to …

Dogs are excellent animal models for human disease. They have extensive veterinary histories, pedigrees, and a unique genetic system due to breeding practices. Despite these advantages, one factor limiting their usefulness is the canine genome reference (CGR) which was assembled using a single purebred Boxer. Although a common practice, this results in many high-quality reads remaining unmapped. To address this whole-genome sequence data from three breeds, Border Collie (n = 26), Bearded Collie (n = 7), and Entlebucher Sennenhund (n = 8), were analyzed to identify novel, non- CGR genomic contigs using the previously validated pseudo-de novo assembly pipeline. We …
Comparison Of Traditional And Alternative Ingredients On Meat Curing Reactions Using A Model System, Faith Rasmussen
Comparison Of Traditional And Alternative Ingredients On Meat Curing Reactions Using A Model System, Faith Rasmussen
Department of Animal Science: Dissertations, Theses, and Student Research
Consumer’s negative perception of “chemical-sounding” ingredients has increased the use of alternative ingredients. The objective of this study was to determine the effect traditional (sodium nitrite with or without sodium erythorbate) or alternative (celery juice powder with or without acerola cherry powder) curing systems with different ingoing concentrations of sodium nitrite using model meat solutions. Curing systems with reducing agents developed the most cured meat pigment (p < 0.001). Using more than 50 ppm of nitrite did not further increase cured meat pigment (p < 0.001). Curing systems with reducing agents and 50 ppm or greater nitrite had the least residual nitrite (p < 0.001). Alternative curing systems had the most residual sulfhydryl groups when formulated with 100 ppm or more nitrite (p < 0.001). Treatments with reducing agents had greater residual reducing capacity than treatments without reducing agents (p < 0.001). Both alternative and traditional curing systems develop similar cured meat pigment but differences in the nitrosation of cysteine exist.

Plasticity Of Foraging Behaviors In Response To Diverse Environmental Conditions, Morgan Gilmour, José Castillo‐Guerrero, Abram Fleishman, Salvador Hernández‐Vázquez, Hillary Young, Scott Shaffer
Faculty Publications, Biological Sciences
Due to rapidly changing global environmental conditions, many animals are now experiencing concurrent changes in both resource availability and the foraging cues associated with finding those resources. By employing flexible, plastic foraging strategies that use different types of environmental foraging cues, animals could adapt to these novel future environments. To evaluate the extent to which such flexibility and plasticity exist, we analyzed a large dataset of a clade (Sulidae; the boobies) of widespread aerial tropical predators that feed in highly variable marine habitats. These surface foragers are typical of many ocean predators that face dynamic and patchy foraging environments and …

The Importance Of Keeping The Big Ones: Harvest Slot Limits And Marine Protected Areas For The Management Of The Caribbean Spiny Lobster, Gayathiri Gnanalingam
The Importance Of Keeping The Big Ones: Harvest Slot Limits And Marine Protected Areas For The Management Of The Caribbean Spiny Lobster, Gayathiri Gnanalingam
Biological Sciences Theses & Dissertations
Fishing typically removes the oldest and/or largest individuals from populations undermining stability and reproductive success. Traditional fisheries management tools fail to protect these oldest and/or largest individuals, but two less conventional tools: marine protected areas (MPAs), and harvest slot limits have the potential to do so. Here I tested the possible use of these tools for the Caribbean spiny lobster, Panulirus argus, an iconic and economically valued species. After decades of intense fishing, the largest lobsters have largely been wiped out. The loss of the largest lobsters is significant as large lobsters have considerably greater reproductive potential than their …

Evaluation Of Dopaminergic And Antidopaminergic Agents For Use In Equine Metabolic Physiology, Nicole Arana Valencia
LSU Doctoral Dissertations
A series of experiments studied the effects and practical applications of dopaminergic and antidopaminergic compounds in equine metabolic physiology. The first experiment was performed to assess the long-term effects of repeated cabergoline injections (every 10 days for a total of seven injections) on prolactin and α-melanocyte stimulating hormone concentrations in insulin insensitive mares. Additionally, the experiment also evaluated the use of cabergoline for improving insulin sensitivity. Plasma prolactin and α-melanocyte stimulating hormone concentrations were suppressed throughout the duration of the experiment even when the mares were challenged with a low-dose dopamine antagonist, sulpiride, the day previous to their subsequent cabergoline …

Can Lactate Dehydrogenase Be Used To Index Anaerobic Activity In Fishes?, Casey W. Schoenebeck, Erik Prenosil, Brianna Pallas, Aspen Abrams, Kimberly Carlson
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
Anaerobic activities such as those associated with spawning, foraging for prey, and predator avoidance are difficult to quantify in wild fish. This study experimentally evaluated if the muscle enzyme lactate dehydrogenase (LDH) can be used to index recent anaerobic activity in fish by testing the hypothesis that muscle LDH activity will be greater in exercised fish than in rested fish. We used burst swimming motions in a swim tunnel to elicit anaerobic metabolism in a 5 day anaerobic exercise treatment (n = 30) and a rested control group (n = 30). On average the exercised fish produced significantly more LDH …
Rivoli's Hummingbird: Eugenes Fulgens, Donald R. Powers
Rivoli's Hummingbird: Eugenes Fulgens, Donald R. Powers
Faculty Publications - Department of Biological & Molecular Science
Rivoli's Hummingbird was named in honor of the Duke of Rivoli when the species was described by René Lesson in 1829. Even when it became known that William Swainson had written an earlier description of this species in 1827, the common name Rivoli's Hummingbird remained until the early 1980s, when it was changed to Magnificent Hummingbird. In 2017, however, the name was restored to Rivoli's Hummingbird when the American Ornithological Society officially recognized Eugenes fulgens as a distinct species from E. spectabilis, the Talamanca Hummingbird, of the highlands of Costa Rica and western Panama.
Rivoli's Hummingbird is found from the …

Ecology Center Publications
A “landscape of fear” (LOF) is a map that describes continuous spatial variation in an animal's perception of predation risk. The relief on this map reflects, for example, places that an animal avoids to minimize risk. Although the LOF concept is a potentially unifying theme in ecology that is often invoked to explain the ecological and conservation significance of fear, little is known about the daily dynamics of an LOF. Despite theory and data to the contrary, investigators often assume, implicitly or explicitly, that an LOF is a static consequence of a predator's mere presence within an ecosystem. We tested …

Food Science Faculty Articles and Research
Catfish belong to the order Siluriformes and include both the Ictaluridae and Pangasiidae families. However, U.S. labeling laws require only species of the family Ictaluridae to be marketed as catfish. The lower production price of Pangasiidae, combined with changes in regulations over time, have resulted in high potential for species substitution and country of origin mislabeling among catfish products. The objective of this study was to conduct a market survey of catfish products sold at the U.S. retail level to examine species mislabeling and compliance with Country of Origin Labeling (COOL) regulations. A total of 80 catfish samples were collected …

Zika virus (ZIKV) can cause various diseases in offspring after congenital infection. The purpose of this study was to identify disease phenotypes in pups exposed to ZIKV in utero. Female interferon-α/β, -γ receptor knockout mice (AG129) were infected intraperitoneally with ZIKV 7.5 days’ post coitus (dpc). Viral RNA, antigen and infectious virus were detected in some, but not all, maternal and fetal tissues at various times during gestation. Fetuses of infected dams had significant intrauterine growth restriction (IUGR), which was more pronounced as females neared parturition. Pups born to infected dams were significantly smaller and had significantly shortened skull …

Common Loons Respond Adaptively To A Black Fly That Reduces Nesting Success, Walter H. Piper, Keren B. Tischler, Andrew Reinke
Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
Nesting birds must often cope with harassment from biting insects, but it is difficult to ascertain what effect such pests might have on breeding success and population dynamics. We tested the hypothesis that a black fly (Simulium annulus) that feeds on the blood of nesting Common Loons (Gavia immer) causes nest abandonment in this charismatic diving bird. In addition, we measured effects of fly-induced abandonment on a loon population, and examined potential predictors of fly abundance and nest abandonment. We also tested a second hypothesis, which holds that loon pairs that abandon a nest owing to …

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)
Businesses in the pet trade collect and transport many aquatic species around the globe, and some of these individuals are released into new habitats. Some jurisdictions have introduced laws intended to regulate this trade, but these regulations have rarely had the desired effects. Laws regarding pets and the pet trade are often poorly communicated, poorly enforced, and not aligned with hobbyists’ beliefs. Consequently, some laws may increase the number of unwanted introductions instead of decreasing them. A significant change in approach is needed, involving far greater communication with scientists, administrations, politicians, the pet industry, and pet owners, promoting euthanasia of …

Small Mammals In Cornfields And Associated Peripheral Habitats In Central Nebraska, Tyson J. Spanel, Keith Geluso
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
In the Great Plains, many native grasslands have been converted to agricultural fields during the last two centuries. Peripheral habitats along edges of crop fields generally consist of linear habitats along roads, with many of these habitats used by native fauna. Our study examined capture rates and species composition of small mammals in cornfields, herbaceous roadside ditches, and wooded shelterbelts in central Nebraska. We captured nine species of small mammals. The Prairie Vole (Microtus ochrogaster) and Western Harvest Mouse (Reithrodontomys megalotis) were captured almost exclusively in roadside ditches, the White-footed Deermouse (Peromyscus leucopus) was …

Seasonal Variations In Trophic Links Between Microzooplankton And Nanoflagellates In A Coastal Ecosystem, An Yi Tsai
Journal of Marine Science and Technology–Taiwan
Using incubation experiments with size-fractionated coastal waters, this study calculated the growth and loss rates of nanoflagellates in a coastal ecosystem of the subtropical western Pacific along a rocky shore in northeastern Taiwan. Samples were taken monthly from September 2014 to August 2015. Seasonal variations in growth rates of heterotrophic nanoflagellates (HNF) and pigmented nanoflagellates (PNF) ranged from 0.17 to 1.13 d-1 and 0.05 to 1.21 d-1, respectively. This study found that grazing had a significant impact on nanoflagellate community (PNF: 0.14 to 0.39 d-1; HNF: 0.12 to 0.52 d-1), accounting for about 15-30% for PNF and 18-60% for HNF …

We aimed to investigate biofouling characteristics on the surfaces of adsorbents and reservoirs used for lithium recovery from seawater. Three types of adsorbents (type 1, 2 m sphere-shaped; type 2, 2 mm circular; and type 3, 2 mm rod-shaped) and a reservoir (polyurethane sponge) were immersed in seawater for 30 days. Biofouling on the surface of adsorbents and the reservoir was initiated by Vibrio, Alteromonas, and Pseudoalteromonas, suggesting that primary colonization of Gammaproteobacteria was an important feature of the biofouling on the surface. We observed pore size-dependent bacterial composition on the adsorbents; only Alteromonas was found on type 1 adsorbent, …
