Assessing The Dispersal And Recruitment Of Stocked Walleye Fry In A Northern Minnesota Chain Of Lakes, Joseph W. Amundson

Biology Graduate Theses

As part of Minnesota's Walleye Sander vitreus egg take practice, 10% of eggs taken for hatchery purposes are stocked back into the donor lake. For Andrusia, part of the Cass Lake Chain of Lakes (Chain), this practice can result in elevated fry densities (mean: 17,000 fry/littoral hectare). However, if fry are able to disperse and use all available littoral hectares throughout the Chain, fry densities would be intermediate to typical stocking densities for Minnesota lakes (1,200 - 2,400 fry/littoral hectare). In 2016-2018, 3-3.5 million fry were mass-marked by immersion in oxytetracycline (OTC) prior to stocking into Andrusia to allow differentiation …

Man V.S. Wild: An Analysis Of Language Used Regarding Human-Wildlife Conflict In The Kibale National Park Community, Western Region, Uganda, Sophie Perfetto

Independent Study Project (ISP) Collection

If humans are to live sustainably and in harmony with wildlife in the vicinity of Protected Areas, policy makers, and government authorities need to make informed decisions with consideration to the needs of local communities. For this to happen, policy makers must understand the perceptions of local communities and take local perspectives into account. As language is at the root of perception, language was studied in the context of its role in shaping local perceptions of human-wildlife conflict and consequential conflict mitigation strategies. Six communities around the Northern region of Kibale National Park, Uganda, were studied, with sites located in …

A Phenological Analysis Of Páramo Vegetation Along An Altitudinal Gradient: The Influence Of Camelids On Andean Flora In The Páramo Of Chimborazo, Ecuador, Tessa Seifried

Independent Study Project (ISP) Collection

This study hopes to reveal the mechanisms behind camelid-plant interactions in the Chimborazo province of Ecuador, which is known for having a large population of domesticated alpacas (Vicugna pacos), along with wild vicuñas (Vicugna vicugna) that were reintroduced into the area 30 years ago. These camelid species, especially vicuñas, are understudied within Ecuador in regards to their effects on plant composition, diversity, and spatial phenology. To gain a better insight into this topic, three sites were chosen: a site inhabited by only vicuña, a site inhabited by only alpaca, and a site inhabited by both species. The vicuña site sat …

A Ladder Of Endemicity: A Pioneering Study Of Anuran Communities Along An Elevational Gradient In The Eastern Andean Cloud Forests, Ecuador, Ella Halbert

Independent Study Project (ISP) Collection

Per unit of area, Ecuador is home to the most herpetofauna of any region on Earth, yet many ecosystems are under researched. Positioned between the Eastern Andes and the Amazon rainforest, the Río Pastaza Basin of Ecuador has been the recent focus of anuran biodiversity surveys and is home to many endemic species. This study aimed to determine how the anuran community composition of a vertical transect in the Llanganates National Park varied between elevations. A 7-day expedition was conducted along a new trail up Abitagua Range spanning 1,050 m in elevation. Each night, visual encounter surveys were employed to …

Beach Suitability For Nesting Olive Ridley Sea Turtles (Lepidochelys Olivacea), Playa Malena, Azuero Peninsula, Panama, Soleil Foy

Independent Study Project (ISP) Collection

Sea turtle species all over the world are facing continuous declines in their populations partly due to diminished viable nesting habitat. Understanding sea turtle nesting preferences and the suitability of beaches for reproductive success is necessary in order to sustain their populations and ensure their conservation. Olive ridley sea turtles (Lepidochelys olivacea) are one of the species experiencing this trend, especially in the Eastern Pacific. This study examined the beach suitability of a site known as Playa Malena in the Azuero Peninsula in Panama for Olive ridley nesting. This site was compared to the suitability of 7 other …

Abundance, Foraging Levels, And Dietary Preferences Of Chaetodon Capistratus On Reefs Surrounding Porvenir Island In The Guna Yala Comarca Of Panamá, Eleanor Ann Casement

Independent Study Project (ISP) Collection

Reef fish are a physically and functionally diverse group of organisms that live in close association with coral reef habitats. Chaetodontidae represents the most species rich family of corallivorous fish, and their reliance on corals as food resources has led to their designation as indicator species of coral cover and health. However, the majority of research on the foraging ecology of Caribbean Chaetodontids dates back several decades, and therefore does not account for recent changes in coral community composition as the result of disease, climate change, and other stressors. As the novel and deadly stony coral tissue loss disease (SCTLD) …

Species distributions are influenced by processes occurring at multiple spatial scales. It is therefore insufficient to model species distribution at a single geographic scale, as this does not provide the necessary understanding of determining factors. Instead, multiple approaches are needed, each differing in spatial extent, grain, and research objective. Here, we present the first attempt to model continent-wide great ape density distribution. We used site-level estimates of African great ape abundance to (1) identify socioeconomic and environmental factors that drive densities at the continental scale, and (2) predict range-wide great ape density. We collated great ape abundance estimates from 156 …

Free-Ranging And Feral Cats, Alex Dutcher, Kyle Pias, Grant Sizemore, Stephen M. Vantassel

Wildlife Damage Management Technical Series

Domestic cats (Felis catus) are a common household pet in the United States, with an estimated 25.4% of households owning cats (American Veterinary Medical Association 2018). While an increasing number of cat owners keep their pet cats exclusively indoors, a portion of society maintains that domestic cats are entitled to a free-ranging lifestyle and may even consider unowned domestic cats to be wildlife. Although wildlife managers recognize the beliefs of many concerned stakeholders, including advocates who use strong emotional appeals on behalf of cats, it remains that free-ranging and feral domestic cats are an invasive species spread by humans (Lowe …

Identification Of Breed Differences In Known And New Fescue Toxicosis Associated Phenotypes In Charolais-And Hereford-Sired Crossbred Beef Cows, Kayla M. Lucas, Dawn A. Koltes, Laura R. Meyer, John D. Tucker, Donald S. Hubbell Iii, Jeremy G. Powell, Jason K. Apple, James E. Koltes

Animal Science Faculty Publications and Presentations

Beef cattle phenotypes are affected by the consumption of toxic fescue. Toxic fescue’s impact is dependent on heat stress and breed composition, with genetic variability for robustness to toxin exposure believed to exist within and across breeds. The study objective was to characterize the effect of fescue toxicosis across breeds for known and novel heat and fescue stress-associated phenotypes. One-hundred crossbred fall-calving Charolais- and Hereford-sired cows of parities 1–3 were allocated to graze either toxic fescue (n = 50), non-toxic fescue (n = 25), or a rotation between toxic and non-toxic fescue (n = 25) for 156 …

Integrated Analyses Of Snp-Genotype And Environmental Data In A Continuously Distributed Snapper Species (Lutjanus Johnii, Bloch, 1792) Reveals A Mosaic Of Populations And A Challenge For Sustainable Management, Laura Taillebois, Danielle Davenport, Diane P. Barton, David Alexander Cook, Thor Saunders, Mark Hearnden, Richard J. Saunders, Stephen J. Newman, Michael J. Travers

Fisheries Research Articles

Understanding population structure is important for predicting the outcomes of anthropogenic development, harvest, and environmental change on the abundance of fisheries species. Logically, the use of several data sources is best for delineating population structure, but combining across data types adds extra challenges as results can be incongruent. Here, genetic and environmental markers were used to test hypotheses about population structure in a collection of 523 tropical inshore finfish (Lutjanus johnii) across northern Australia from 20 locations. Redundancy analyses (RDA) were used to statistically test for correlations among data sources providing a basis for reconciliation and insights into ecological and …

In summer 2020, Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) was detected on mink farms in Utah. An interagency One Health response was initiated to assess the extent of the outbreak and included sampling animals from on or near affected mink farms and testing them for SARS-CoV-2 and non-SARS coronaviruses. Among the 365 animals sampled, including domestic cats, mink, rodents, raccoons, and skunks, 261 (72%) of the animals harbored at least one coronavirus. Among the samples that could be further characterized, 127 alphacoronaviruses and 88 betacoronaviruses (including 74 detections of SARS-CoV-2 in mink) were identified. Moreover, at least 10% (n …

Variations, Validations, Degradations, And Noninvasive Determination Of Pregnancy Using Fecal Steroid Metabolites In Free-Ranging Pronghorn, Cole A. Bleke, Eric M. Gese, Susannah S. French

United States Department of Agriculture Wildlife Services: Staff Publications

Pregnancy status is a key parameter used to assess reproductive performance of a species as it represents a starting point for measuring vital rates. Vital rates allow managers to determine trends in populations such as neonate survival and recruitment; two important factors in ungulate population growth rates. Techniques to determine pregnancy have generally involved capture and restraint of the animal to obtain blood samples for determining serum hormone levels. Non-invasive pregnancy assessment, via feces, eliminates any hazards between handler and animal, as well as removes handling-induced physiological biases. Using noninvasive fecal sampling, we conducted hormone validations, investigated pregnancy rates, and …

With rates of psychiatric illnesses such as depression continuing to rise, additional preclinical models are needed to facilitate translational neuroscience research. In the current study, the raccoon (Procyon lotor) was investigated due to its similarities with primate brains, including comparable proportional neuronal densities, cortical magnification of the forepaw area, and cortical gyrification. Specifically, we report on the cytoarchitectural characteristics of raccoons profiled as high, intermediate, or low solvers in a multiaccess problem-solving task. Isotropic fractionation indicated that high-solvers had significantly more cells in the hippocampus (HC) than the other solving groups; further, a nonsignificant trend suggested that this …

Satellite-Detected Ammonia Changes In The United States: Natural Or Anthropogenic Impacts, Yaqian He, Rongting Xu, Stephen A. Prior, Di Yang, Anni Yang, Jian Chen

United States Department of Agriculture Wildlife Services: Staff Publications

Ammonia (NH3) is the most abundant alkaline component and can react with atmospheric acidic species to form aerosols that can lead to numerous environmental and health issues. Increasing atmospheric NH3 over agricultural regions in the US has been documented. However, spatiotemporal changes of NH3 concentrations over the entire US are still not thoroughly understood, and the factors that drive these changes remain unknown. Herein, we applied the Atmospheric Infrared Sounder (AIRS) monthly NH3 dataset to explore spatiotemporal changes in atmospheric NH3 and the empirical relationships with synthetic N fertilizer application, livestock manure production, and climate factors across the entire US …

Adaptation Of An Artificial Bait To An Automated Aerial Delivery System For Landscape-Scale Brown Treesnake Suppression, Rafael A. Garcia, Thomas W. Mcauliffe, Lorelie P. Bumanlag, Shane R. Siers, Bruce A. Kimball

United States Department of Agriculture Wildlife Services: Staff Publications

Dead neonatal mice are currently used as bait for delivery of toxin to invasive brown treesnakes (Boiga irregularis) on Guam; once deployed in the field the mice are highly attractive to the snakes but only for about four days. An artificial bait containing a mixture of fats mimicking those in skin of the mice is also highly attractive to the snakes and remains attractive 2–3 times longer. The artificial bait, however, costs more than the mice, and is more difficult to attach to the capsules of a novel aerial bait delivery system. This paper describes a reformulation of the bait …

Movement, Space-Use And Resource Preferences Of European Golden Jackals In Human-Dominated Landscapes: Insights From A Telemetry Study, Skye Fenton, Paul R.

During the last half-century, the distribution of golden jackals (Canis aureus) has rapidly increased throughout Europe. Today, golden jackals are thriving in human-dominated landscapes across Southeastern and Central Europe. Most studies on golden jackals have focused on large-scale distribution patterns; to date, little is known about the species’ fine-scale spatial ecology. In this study, we analyzed the movement behavior, space-use and resource selection of six golden jackals fitted with GPS-GSM collars in two study areas in Hungary and Serbia. Two of the jackals were a breeding pair. We found that home range size averaged 11.2 km² (90% …

Effects Of Translocation On Survival Of Nuisance Bears, Javan Bauder, D. Ruid, N. M. Roberts, B. Kohn, M. L. Allen

United States Department of Agriculture Wildlife Services: Staff Publications

Effective mitigation of human–wildlife conflict should aim to reduce conflicts while also minimizing wildlife mortality. Translocation is often used to mitigate human–wildlife conflict but translocated individuals may have reduced survival, which could negatively affect population growth and social acceptance of translocation as a management tool. Yet, non-translocated nuisance individuals may also have low survival due to inherent risks associated with nuisance behavior. We used a 38-year dataset of 1233 marked and translocated nuisance American black bears (Ursus americanus) as a model system with which to evaluate the impacts of translocation on nuisance bear survival. We used multi-state mark-recapture models to …

Threading The Needle: How Humans Influence Predator–Prey Spatiotemporal Interactions In A Multiple-Predator System, Asia Murphy, Duane R. Diefenbach, Mark Ternent, Matt Lovallo, David Miller

United States Department of Agriculture Wildlife Services: Staff Publications

Perceived predation risk and the resulting antipredator behaviour varies across space, time and predator identity. Communities with multiple predators that interact and differ in their use of space, time of activity and hunting mode create a complex landscape for prey to avoid predation. Anthropogenic presence and disturbance have the potential to shift interactions among predators and prey and the where and when encounters occur. We examined how white-tailed deer Odocoileus virginianus fawn spatiotemporal antipredator behaviour differed along an anthropogenic disturbance gradient that had black bears Ursus americanus, coyotes Canis latrans, bobcats Lynx rufus and humans present. We quantified (a) spatial …

The Gap Between Policy And The People: A Case Study Of The Buikwe Fishing Communities, Capri Gutiérrez

Independent Study Project (ISP) Collection

To examine the implementation of Local Government development planning in periphery and hard to reach communities in Uganda, the fishing villages of the Buikwe District were used as a case study. The objective of the study was to explore how Local Government development planning is implemented in the fishing villages to identify gaps. Implementation was broken down into three areas: consultations, needs and services, and service delivery.

The study mimicked the bottom-up approach to decentralized development planning in Uganda, beginning with seven focus group discussions in five fishing villages of Buikwe. Eleven key informant interviews were then conducted with Local …

An Eventful Past Predicting A Bizarre Future: Assessing The Influence Of Ocean Circulation On Key Fish Species In Icelandic Waters. An Analysis Of Past Circulation Records In Order To Predict The State Of Demersal Fish Stocks In Future Climate Scenarios, Matthew Engfer

Independent Study Project (ISP) Collection

Feedback-driven changes in North Atlantic Ocean circulation are affecting marine ecosystems off the coast of Iceland and are predicted to have differing outcomes by 2100. In this study, data reflecting Icelandic fish stock distributions was compiled on a map with oceanographic temperature and depth in order to observe patterns of population changes with changes in ocean currents. After evaluating past temperature effects on demersal fish stocks, future habitat predictions were estimated in weaker ocean circulation scenarios. A number of assumptions were made in order to pinpoint a correlation between ocean temperature and fish habitat. Iceland’s unique location and climate offers …

Bird Diversity In The Ecuadorian Chocó: A Proposal For Avitourism In Villaflora And Manduriacu Reserve, Elizabeth Kroger

Independent Study Project (ISP) Collection

Ecuador is rich in avifauna, and the Chocó bioregion of Northwestern Ecuador is a hotspot for bird endemism and diversity. However, many rare and beautiful species are threatened by human activities such as logging and mining. It is essential that communities are able to find alternative solutions that bring economic benefits and improve public health. Avitourism is an economically beneficial and environmentally friendly solution. This study examined avifaunal biodiversity in Villaflora and Manduriacu Reserve, a small town in the cloud forest of the Chocó region. Point counts on pre-existing trails were used to assess bird communities as well as search …

How Birds During Migration Maintain (Oxidative) Balance, Scott R. Mcwilliams, Wales A. Carter, Clara Cooper-Mullin, Kristen J. Demoranville, Abigail E. Frawley, Barbara J. Pierce, Megan Skrip

Biology Faculty Publications

Animals dynamically adjust their physiology and behavior to survive in changing environments, and seasonal migration is one life stage that demonstrates these dynamic adjustments. As birds migrate between breeding and wintering areas, they incur physiological demands that challenge their antioxidant system. Migrating birds presumably respond to these oxidative challenges by up-regulating protective endogenous systems or accumulating dietary antioxidants at stopover sites, although our understanding of the pre-migration preparations and mid-migration responses of birds to such oxidative challenges is as yet incomplete. Here we review evidence from field and captive-bird studies that address the following questions: (1) Do migratory birds build …

Assessing the body condition of wild animals is necessary to monitor the health of the population and is critical to defining a framework for conservation actions. Body condition indices (BCIs) are a non-invasive and relatively simple means to assess the health of individual animals, useful for addressing a wide variety of ecological, behavioral, and management questions. The Antillean manatee (Trichechus manatus manatus) is an endangered subspecies of the West Indian manatee, facing a wide variety of threats from mostly human-related origins. Our objective was to define specific BCIs for the subspecies that, coupled with additional health, genetic and …
