Flashtags: Evaluating A Novel Deterrent To Reduce Livestock Depredation, C. Aaron Bott, Stewart W. Breck, Tom W. Murphy, Brad A. Freking, Carlos A. López González, David Prause, Corey Peavey, Albert Sommers, Coke Landers, Julie K. Young

Human–Wildlife Interactions

Social tolerance of carnivores can be improved by preventing conflicts through nonlethal predator deterrents (e.g., livestock protection dogs [Canis lupus familiaris] and human presence) that have been used for centuries. However, many livestock producers feel the existing preventative methods are inadequate for extensive production systems where livestock can be spread widely and have less human supervision. To address this issue, we developed and tested a new nonlethal tool called FlashTags to reduce livestock predation. FlashTags are ear tags worn by livestock that flash a random-light pattern at night when motion-triggered. In the first year, we tested the devices …

Multi-Year Effectiveness Of Pzp-22 In Free-Roaming Suburban White-Tailed Deer, Allen T. Rutberg, Kali M. Pereira, Kayla A. Grams, John W. Turner Jr.

Human–Wildlife Interactions

To address the challenge that is posed to the use of fertility control to mitigate human–deer (Cervidae) conflicts by the need to regularly re-inoculate free-roaming animals, we captured, ear-tagged, and hand-injected 68 individual adult female white-tailed deer (Odocoileus virginianus) with the PZP-22 immunocontraceptive vaccine from February through April, 2014 to 2017, in the Village of Hastings-on-Hudson, New York, USA. Approximately 2.5 years after initial treatments, we booster-darted 29 of the previously treated females with either PZP-22 or native PZP (ZonaStat-D). We observed fawn production between 2014 and 2021. The combination of initial PZP-22 hand-treatments followed by single dart-delivered PZP …

Spatial Predictors Of Human–Black Bear Interactions In Nova Scotia, Canada, Jason I. Airst, Tricia B. Fleming

Human–Wildlife Interactions

The increased global frequency of human–wildlife conflict with large, wild carnivores and omnivores negatively impacts human, wildlife, and ecosystem health. The goal of this study was to determine what landscape characteristics best predicted where human–black bear (Ursus americanus) interactions occurred in Nova Scotia, Canada, to support management efforts. We compared the location of 3,278 human–bear conflict reports and 867 non-conflict reports collected between 2017 and 2021 to 12,000 randomly generated locations. Data were analyzed using logistic additive mixed models. We found that interactions (conflict and non-conflict reports) occurred near roads and farther from forests and surface water features. …

Is Mitigation Translocation An Effective Method For Reducing Laysan Albatross–Military Aircraft Collisions?, Brian E. Washburn, Katherine D. Rubiano, William P. Bukoski

Human–Wildlife Interactions

Wildlife–aircraft collisions (wildlife strikes) pose a serious risk to civil and military aircraft. Each year, Laysan albatrosses (Phoebastria immutabilis) attempt to establish a breeding colony on the airfield at the U.S. Navy’s Pacific Missile Range Facility (PMRF) located on the island of Kaua‘i, Hawai‘i, USA, resulting in a hazard to safe military aircraft operations at this facility. A long-term management program, with an emphasis on mitigation translocation (e.g., live-capture and translocation away from the area) of problematic individuals, has been conducted by the U.S. Department of Agriculture, Wildlife Services. However, the efficacy of mitigation translocation as a nonlethal …

Waterbird-Perceived Damage, Control Measures, And Economic Implications For Rice Production In The Brazilian Cerrado, Demetrio Luis Guadagnin, Alexandre Afonso Meyer, João Augusto Rossi Borges, Fernanda Maia Justo

Human–Wildlife Interactions

Waterbirds have the potential to inflict economic damage to crops. However, is rice (Oryza sativa) production in the Brazilian Cerrado significantly affected by waterbirds? This study aimed to assess the extent of waterbird damage on irrigated rice production in Central Brazil. We conducted surveys of waterbird populations in rice agroecosystem habitats throughout the cultivation cycle and analyzed the expenses associated with waterbird-induced yield losses and the control measures employed by farmers. The 2 most prevalent waterbird species observed were Dendrocygna viduatta and D. autumnalis, comprising 68.6% of all recorded waterbirds. These species were more frequently encountered and …

The Spatial Ecology Of Plains Spotted Skunks In South Dakota: Insights From Species Distribution, Resource Selection, And Co-Occurrence Models, Kara M. White

Electronic Theses and Dissertations

The plains spotted skunk (Spilogale interrupta) is a data-deficient small carnivore native to the central plains of North America that has experienced significant population declines. My dissertation investigates the species’ distribution, habitat associations, and interspecific interactions in South Dakota, providing crucial information for conservation actions. In Chapter 1, I developed ensemble distribution models on a broad scale, incorporating species location data from 1985–2020, environmental factors, and six predictive modeling algorithms. I identified key predictors including mean temperature diurnal range and proportion of area as pasture, and estimated ~31,300 km2 of potential habitat, predominately in eastern South Dakota. In Chapter 2, …

Soil Responses To Eastern Redcedar (Juniperus Virginiana L.) Afforestation And Prescribed Fire In South-Central South Dakota, Robert Schaefer

Electronic Theses and Dissertations

Research was conducted in 2019 and 2020 on rangelands located in south-central South Dakota assessing a number of physical, chemical, and biological properties of mineral ustepts and ustents soils associated with eastern redcedar (ERC) (Juniperus virginiana) afforestation and prescribed fire. ERC afforestation appeared to be associated with significantly higher field-condition soil aggregate stability, cation exchange capacity (CEC), soil pH, and fungi:bacteria (F:B) as well as significantly lower soil moisture, nitrate-N, phosphorus, bacteria biomass, and Gram-positive:Gram-negative (GP:GN) bacteria compared to native grassland conditions, while other mineral soil properties appeared relatively unaffected. Compared to soil conditions under dense, living ERC canopies, prescribed …

Methods For Optimizing Detection And Evaluating Habitat Use Of North American River Otters In South Dakota, Jessica Speiser

Electronic Theses and Dissertations

North American river otters (Lontra canadensis) play a critical role as an apex predator in riverine ecosystems. A challenging species to survey using traditional methods, they remain understudied in non-forested regions, such as the Northern Great Plains, where habitat degradation and landscape fragmentation may reduce habitat quality and availability and disrupt landscape connectivity. This thesis aims to improve detectability and investigates the habitat use of river otters in South Dakota to better understand habitat needs of otters and improve their continued recovery and management. My first chapter provides a brief overview of river otters and their ecological roles in freshwater …

The Effects Of Beaver Dam Anaolgs On Linked Aquatic-Terrestrial Communities In Western Headwater Streams, Michelle Elyse Fillion, Benjamin P. Colman, Rachel L. Malison

Graduate Student Theses, Dissertations, & Professional Papers

In response to stream degradation resulting from the near eradication of American Beavers (Castor canadensis), managers of freshwater systems have turned to using beaver dam analogs (BDAs) as one means of restoring waterways from stream and riparian degradation. Though BDAs have been shown to restore physical traits of riparian areas, their influence on macroinvertebrates and linked aquatic-terrestrial systems is not well understood. To examine how BDAs influence aquatic habitats, macroinvertebrate communities, and riparian insectivores, we compared unrestored reference stream segments to BDA-restored segments with 7-14 BDAs in three western Montana headwater streams. We collected physical stream measurements and quantitative samples …

Habitat Selection And Connectivity Of Mountain Lions (Puma Concolor) Across Anthropogenic Barriers On The Olympic Peninsula: A Multi-Method Comparison, Thomas R. Barbee

Graduate Student Theses, Dissertations, & Professional Papers

Designing and maintaining effective wildlife corridors is an increasingly important conservation challenge in today’s fragmenting landscapes. GPS-based resource selection functions and camera-based occupancy models are both well-established staples of wildlife connectivity analyses and corridor planning, but each have notable trade-offs in cost and data resolution. Wildlife organizations worldwide rely heavily on camera-based occupancy modelling to plan wildlife corridors, especially where resource limitations or ethical concerns prohibit the use of GPS tags. If spatial connectivity maps from occupancy models could be shown to capture the essential elements of animal movement well enough to identify functionally equivalent corridors to those identified in …

The Hare And The Hawk: Predator, Prey, And Coat Color Mismatch In A Polymorphic Snowshoe Hare Population, Amanda Shuler Emmel

Graduate Student Theses, Dissertations, & Professional Papers

Climate change effects on predator-prey interactions are complex and poorly understood, with few study systems that explicitly connect specific antipredator traits to particular climate drivers. Such a system can be found in seasonal coat color change, whereby 21 species globally molt from a summer brown to a winter white coat to maintain camouflage with seasonal snow. Snowshoe hares (Lepus americanus) contend with increased predation due to climate-change induced coat color mismatch under decreasing snowcover. Through a combination of field experiments in the central Cascade mountains, my thesis investigates snowshoe hare mismatch and predation risk from both a predator …

Moose Abundance And Calf:Cow Ratios On The Blackfeet Indian Reservation And Glacier National Park, Landon Joel Magee

Graduate Student Theses, Dissertations, & Professional Papers

Many moose (Alces alces; Sikihtsisoo) populations across North America, especially along their southern range, are declining due to factors such as climate change, parasites and disease, predation, habitat loss and degradation, and overharvest. These declines highlight broader ecological concerns, as moose play a critical role as prey within their ecosystems. Despite their importance, data on crucial demographic parameters like abundance and age ratios are sparse for moose, complicating management efforts. Conventional monitoring methods, including radio-collaring, harvest data, public surveys, and aerial surveys, face significant logistical and financial challenges, and often fail to provide a comprehensive understanding of …

Quantifying Wastewater Contributions To The Upper Clark Fork River, Claire Utzman

Graduate Student Theses, Dissertations, & Professional Papers

Though algae are at the base of food webs in many rivers, large algal blooms are increasing in frequency and can cause problems with nutrient cycling, depletion of oxygen supplies at night, and release of toxic chemicals. One leading cause of algal blooms is nutrient loading into rivers, and controlling nutrient release in wastewater is one approach that can help limit algal growth. To reduce the intensity of algal blooms in the Clark Fork River in western Montana, numeric nutrient standards were put in place that regulated the release of the nutrients nitrogen and phosphorus into the river from wastewater. …

Bird Predation On Coho Salmon (Oncorhynchus Kisutch) In Humboldt Bay, Colton J. Dixon

Cal Poly Humboldt theses and projects

Coho Salmon (Oncorhynchus kisutch) populations along the west coast of the United States are declining. In Humboldt County, located in northwestern California, Coho Salmon have been in decline since their federal listing as threatened in 1997, primarily due to habitat loss from logging, agriculture, and urban development. Although these anthropogenic factors caused salmon populations to decline, bird predation may also be hindering population recovery, as evidenced by the recovery of Passive Integrated Transponder (PIT) tags, originally implanted in Coho Salmon, from bird colonies in Humboldt Bay. This study examines predation by Double-crested Cormorants (Phalacrocorax auritus), Caspian …

Examining The Drivers Of Nocturnal Behavior Of Pikas At Lower Elevations In Lassen National Forest, California, Evan Burnett

Cal Poly Humboldt theses and projects

The American pika (Ochotona princeps) is a charismatic mammal species adapted to occupy rockslides and boulder fields in western North America. Historically monitored due to their climate sensitivity, pikas have experienced extirpations along their lower range margins—driven by chronic and acute temperature stress—prompting increased concern and monitoring over the risks posed by anthropogenic climate change. Traditionally considered an alpine species, pikas occupy a wide range of elevations, with those at lower elevations exhibiting higher rates of nocturnality than their counterparts at higher elevations. Temperature is hypothesized to be the driver, but this has yet to be confirmed. Pikas …

Barn Owls Exert Top-Down Effects On The Abundance And Behavior Of Rodent Pests, Katherine C. Larson

Cal Poly Humboldt theses and projects

Predators can exert top-down effects on their prey by direct consumption, by imposing risk of predation, or a combination of both. However, empirical evidence for these effects is mixed and inconsistent. Barn owls in agriculture present a system with attributes that should, according to theory, lead to strong top-down effects, but research is limited and the distinction between effects on prey abundance and behavior remains unresolved. Understanding the top-down effect of predators on pests is a cornerstone of integrated pest management and important where barn owls may contribute to the control of rodents on farms. Vegetation can mediate the top-down …

Microbes: Key Constituent Of Predator Risk Cues?, Jake R. Vargas

Cal Poly Humboldt theses and projects

Chemical cues emanating from predators can play a key role in aquatic predator-prey interactions and food webs. Understanding how prey respond to these risk cues is therefore critical for understanding the direct effects of predators on prey populations and their indirect effects on communities. To respond adaptively, prey must accurately assess the risk of predation associated with perceived chemical cues, an oft-documented phenomenon. However, little is known about how cues disperse, persist, and degrade, all of which could limit the adaptive responses of prey. Using laboratory-based observations of a well-studied predator cue-induced antipredator behavior by the marine gastropod Tegula funebralis …
