Mathematics, Physics, and Computer Science Faculty Articles and Research

Undocumented historical losses of sea turtle nesting beaches worldwide could overestimate the successes of conservation measures and misrepresent the actual status of the sea turtle population. In addition, the suitability of many sea turtle nesting sites continues to decline even without in-depth scientific studies of the extent of losses and impacts to the population. In this study, multidecadal changes in the outlines and area of Jana and Karan islands, major sea turtle nesting sites in the Arabian Gulf, were compared using available Kodak aerographic images, USGS EROS Declassified satellite imagery, and ESRI satellite images. A decrease of 5.1% and 1.7% …

Functional Morphology Of Gliding Flight Ii. Morphology Follows Predictions Of Gliding Performance, Jonathan Rader, Tyson L. Hedrick, Yanyan He, Lindsay D. Waldrop

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

The evolution of wing morphology among birds, and its functional consequences, remains an open question, despite much attention. This is in part because the connection between form and function is difficult to test directly. To address this deficit, in prior work we used computational modeling and sensitivity analysis to interrogate the impact of altering wing aspect ratio, camber, and Reynolds number on aerodynamic performance, revealing the performance landscapes that avian evolution has explored. In the present work, we used a dataset of three-dimensionally scanned bird wings coupled with the performance landscapes to test two hypotheses regarding the evolutionary diversification of …

Functional Morphology Of Gliding Flight I. Modeling Reveals Distinct Performance Landscapes Based On Soaring Strategies, Lindsay D. Waldrop, Yanyan He, Tyson L. Hedrick, Jonathan Rader

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

The physics of flight influences the morphology of bird wings through natural selection on flight performance. The connection between wing morphology and performance is unclear due to the complex relationships between various parameters of flight. In order to better understand this connection, we present a holistic analysis of gliding flight that preserves complex relationships between parameters. We use a computational model of gliding flight, along with analysis by uncertainty quantification, to 1) create performance landscapes of gliding based on output metrics (maximum lift-to-drag ratio, minimum gliding angle, minimum sinking speed, lift coefficient at minimum sinking speed); and 2) predict what …

Spatial Ecology And Resource Selection Of Bighorn Sheep (Ovis Canadensis) Ewes In A Prairie Badlands Population, Erin Wood

School of Natural Resources: Dissertations, Theses, and Student Research

The basic spatial ecology and habitat relationships of female bighorn sheep in Nebraska are poorly understood. Establishing seasonal patterns of space use and resource selection for this population at the margin of their historical and current range addresses a key knowledge gap and provides important baseline information for ongoing conservation efforts in Nebraska. We deployed GPS radio-collars on 56 adult ewes in western Nebraska to quantify seasonal space use, movements, and resource selection of ewes. To investigate spatial ecology, we quantified movements of ewes and the factors that influence home range size, seasonal use, and spatial stability across seasons. Home …

A Survey Of Dairy-Goat Keeping In Zanzibar, Tiffanie Stone, Charles A. Francis, L. O. Eik

Department of Agronomy and Horticulture: Faculty Publications

Dairy goats with improved genetics for milk production were recently introduced onto small-scale farms in Zanzibar through governmental and non-governmental projects. These projects were meant to support small-scale farmers by improving both income and household nutrition through milk production. No follow up had been conducted to understand what effects dairy goat keeping had on these small-scale farms, or how they could be improved. A survey of 193 dairy goat farmers in Zanzibar was conducted, including 30% and 60% of all dairy goat farmers on Unguja and Pemba, the two largest islands, respectively. The objective was to understand the impact keeping …

The Pocatello Supply Depot: A History And Update, Patrick A. Darrow

Vertebrate Pest Conference Proceedings: 29th (2020)

Since the Pocatello Supply Depot (PSD) was created in 1936, the PSD has gone through many transformation and organizational changes. The most recent of these changes occurred in 2014, when the PSD transitioned from a cooperative service agreement between the U.S. Department of Agriculture (USDA) and the Greater Pocatello Chamber of Commerce, to a fully federal facility within USDA. Despite the many organizational changes, the purpose of the PSD has remained the same. The PSD manufactures and provides specialized wildlife damage management materials and services that are not readily available from commercial sources, for use by USDA Wildlife Services (WS), …

Assessing Beaver Occupancy And Dam Building Potential: A Case Study In The Umpqua Watershed Of Southwestern Oregon, Vanessa M. Petro, John Stevenson, Jimmy Taylor

Vertebrate Pest Conference Proceedings: 29th (2020)

Interest in beaver-related restoration is growing in the western U.S. but understanding the basic ecology of American beaver and their population dynamics is often overlooked when integrating beaver into stream restoration goals. Our study investigated the spatial-temporal distribution of beaver colonies and their damming activities to better inform stream restoration projects in the West Fork Cow Creek Basin of the Umpqua Watershed in southwestern Oregon. During fall 2017, we conducted beaver activity surveys at 144 randomly selected reaches predicted to be either suitable or unsuitable for damming, but suitable for beaver occupation. We categorized beaver use at each reach using …

Automated Aerial Baiting For Invasive Brown Treesnake Control: System Overview And Program Status, Shane R. Siers, John D. Eisemann, William C. Pitt, Larry Clark, Scott M. Goetz, Robert J. Gosnell, Aaron F. Collins, Eric T. Hileman, Melia G. Nafus, Amy A. Yackel Adams, Michael C. Messaros, William G.N. Coon

Vertebrate Pest Conference Proceedings: 29th (2020)

The economically and ecologically catastrophic introduction of invasive brown treesnakes to the Pacific Island of Guam has long served as a cautionary tale about the dangers of invasive species and the seeming impossibility of their management on a landscape scale. USDA Wildlife Services and federal and private partners have engineered a system for the automated manufacture and aerial delivery of toxic baits for landscape-scale suppression of brown treesnakes in large and remote forest plots. The helicopter-borne dispensing module can launch four bait cartridges per second, and a single payload of 3,600 cartridges can treat 30 ha of forest at 120 …

A Preliminary Field Evaluation Of Candidate Repellents To Reduce Black Bear Damage To Western Larch Trees, G. W. Witmer, Michael Pipas

Vertebrate Pest Conference Proceedings: 29th (2020)

Bear damage to western larch trees on intensively managed public and private forest lands of the Intermountain West continues to be a problem for forest managers. Bark stripping and subsequent cambium feeding by bears commences upon den emergence in the spring, when foraging options are most restrictive. Various damage reduction methods are often controversial (snaring, hunting, supplemental feeding), or do not always adequately resolve the problem (silvicultural strategies); hence, a need exists for the development of alternative nonlethal techniques to reduce damage. We tested the efficacy of three candidate repellents (Hot Sauce®, Tree Guard™, and grizzly bear feces) to reduce …

Understanding And Preventing Bird Damage On Dairies, Amber Adams-Progar, Karen Steensma, Stephanie A. Shwiff, Julie L. Elser, Susan Kerr, Tyler P. Caskin

Vertebrate Pest Conference Proceedings: 29th (2020)

Wild birds cause significant damage to dairy farms through the consumption and spoilage of cattle feed. A survey of Washington State dairy farmers revealed approximately $14 million in bird damage losses for the Washington State dairy industry, annually. Furthermore, farms that reported the presence of more than 10,000 birds per day were more likely to report the presence of Salmonella spp. or Johne’s disease (caused by Mycobacterium avium subsp. paratuberculosis). Over the course of three years, we assessed the impact of bird populations on the presence of bacteria in bird feces and the nutritional composition of cattle feed. Five dairies …

Island Rodent Eradications: Little Things Make Big Things Happen, Araceli Samaniego-Herrera, Peter J. Kappes, Shane R. Siers

Vertebrate Pest Conference Proceedings: 29th (2020)

Island rodent eradication is often a prerequisite for ecological restoration. These operations have been scaling up in size and complexity, and typically revolve around the thorough distribution of rodenticides in bait stations, by hand broadcast, by helicopter-borne spreading buckets, or by combinations of these methods. Many of the requirements of an eradication can be met by simply purchasing the right materials and following published best practices. However, intangible factors such as training and mindset of personnel are equally critical, and less commonly understood. We briefly review these factors and highlight issues such as the limited pool of experienced eradication practitioners, …

If At First You Don’T Eradicate: Remediating Rat Eradication Failure On Wake Atoll, Peter J. Kappes, Shane R. Siers, Kristen Rex, Chad Hanson

Vertebrate Pest Conference Proceedings: 29th (2020)

Island rodent eradication operations have been remarkably successful at eliminating damages caused by these harmful vertebrate pests. As efforts increase in scale and complexity, so does risk of eradication failure. In this paper we present the example of a partially successful rodent eradication project to highlight how best practices and lessons learned are being integrated to reduce risk of failure during a second attempt. In 2012 the U.S. Air Force (USAF) commissioned an attempted eradication of two rat species from Wake Atoll in the Western Pacific. Asian house rats were successfully eradicated, but it was soon confirmed that some Polynesian …

Laboratory Evaluation Of The Effectiveness Of The Fertility Control Bait Contrapest® On Wild-Captured Black Rats (Rattus Rattus), Shane Siers, Robert T. Sugihara, Israel Leinbach, Brandy R. Pyzyna, Gary Witmer

Vertebrate Pest Conference Proceedings: 29th (2020)

A non-toxic liquid fertility control bait for rats has recently become commercially available (ContraPest® from SenesTech, Inc.). This product contains two chemicals, both of which impair spermatogenesis in male and reduce ovulations in female rats. We tested the efficacy of this bait in wild-caught adult black rats from the island of Hawai’i in a short-term laboratory trial. A control group (n = 25) was offered placebo bait and the treatment group (n = 25) was offered fertility control bait, both ad libitum, during a 15-day introduction period and during the first of four breeding rounds, for a total of 58 …

Development And Testing Of A Matrix For Mongoose Toxic Bait: Nontoxic Bait Acceptance Cage Trials, Shane Siers, Robert T. Sugihara, Israel Leinbach, Daniel Sedgwick, Chris N. Niebuhr, Emily W. Ruell

Vertebrate Pest Conference Proceedings: 29th (2020)

The only pesticide currently registered for mongoose control is a product developed for rats that consists of a hard-cereal bait block. Although the active ingredient (diphacinone) is known to be highly effective for mongoose, previous studies indicate that carnivorous and omnivorous mongooses do not readily consume the hard bait matrix designed for gnawing rodents. A palatable bait matrix with a consistency more appropriate to mongoose dentition and feeding behavior will be required to develop a more effective mongoose pesticide. We evaluated the acceptance and consumption of nontoxic versions of four candidate bait matrices: FOXECUTE® and FOXSHIELD® (Animal Control Technologies, Australia; …

Feasibility Of A Successful Rat Eradication On Wake Atoll Following Initial Partial Failure: Potential Causes, Remedial Actions, And Remaining Knowledge Gaps, Chad Hanson, Kristen Rex, Peter J. Kappes, Shane R. Siers

Vertebrate Pest Conference Proceedings: 29th (2020)

A 2012 attempt to remove two rat species (Rattus tanezumi and R. exulans) from Wake Atoll was partially successful. R. tanezumi was eradicated from all three islands (Wake, Wilkes, and Peale), and R. exulans was eradicated from Peale. However, R. exulans remained on Wake and Wilkes and have since recovered to very high densities. In 2013, a panel of experts reviewed the eradication operation and offered a list of possible causes of the partial failure. Since that time, further research has been conducted to address several of the issues identified in the review. In this paper, we conduct a current …

Placebo Bait Uptake Trial To Test Feasibility Of Polynesian Rat (Rattus Exulans) Eradication On Wake Atoll, Chris N. Niebuhr, Israel Leinbach, Thomas W. Mcauliffe, Dean K. Foster, Shane R. Siers

Vertebrate Pest Conference Proceedings: 29th (2020)

Rodent eradications have contributed to the recovery of many threatened species, but challenges often exist for campaigns that occur on tropical islands when compared to more temperate regions. A post-operational review of a rat eradication operation on Wake Atoll indicated that certain areas, such as those with high alternative food abundance, may have contributed to the failure to remove all Polynesian rats. We conducted a nontoxic bait uptake trial to evaluate whether the maximum prescribed bait application rate for Brodifacoum-25W rodenticide pellets was sufficient to expose all rats to a lethal dose at three sites on Wake Atoll, including around …

An Assessment Of Convergence In The Feeding Morphology Of Xiphactinus Audax And Megalops Atlanticus Using Landmark-Based Geometric Morphometrics, Edward Chase Shelburne

Master's Theses or Doctor of Nursing Practice

Convergence is an evolutionary phenomenon wherein distantly related organisms independently develop features or functional adaptations to overcome similar environmental constraints. Historically, convergence among organisms has been speculated or asserted with little rigorous or quantitative investigation. More recent advancements in systematics has allowed for the detection and study of convergence in a phylogenetic context, but this does little to elucidate convergent anatomical features in extinct taxa with poorly understood evolutionary histories. The purpose of this study is to investigate one potentially convergent system—the feeding structure of Xiphactinus audax (Teleostei: Ichthyodectiformes) and Megalops atlanticus (Teleostei: Elopiformes)—using a comparative anatomical approach to assess …

The Effect Of Neonicotinoid Clothianidin On Ring-Necked Pheasant Survival And Reproduction, Michael Sundall

Electronic Theses and Dissertations

Ring-necked pheasants (Phasianus colchicus) are economically important to the state of South Dakota bringing in over one hundred million dollars in revenue each season. The population is known to fluctuate temporally for many reasons, often weather related. Unfortunately, no research has been conducted involving ring-necked pheasants that evaluated the impact or interaction of neonicotinoids on the species. The objective of our study was to gain an understanding of how the neonicotinoid, Clothianidin, affects survival and breeding in pheasants. Our first experiment was to determine if there was a selection bias for seeds treated with neonicotinoids. In this experiment, eight ring-necked …

First Records For Spawning Of Caribbean Acropora Species In Colombian Mpas, David M. Hudson, Barrett L. Christie, Luis A. Gómez-Lemos, Camilo Valcarcel, Diego Duque, Juan C.

Gulf and Caribbean Research

Estimates of Colombian Caribbean coral percent cover in the Southern Caribbean are consistent with those throughout the Caribbean Sea, which has declined to about 10% of historical levels in the last few decades. Human activities like destructive fishing techniques in the marine parks have degraded the reefs over the last few decades. Colombia’s Marine Protected Areas (MPAs) have thousands of square kilometers to map and patrol and few resources to devote to scientific and restoration efforts. Efforts to implement sexual reproduction techniques for restoration are starting to successfully propagate and settle corals on ceramic plates for reef deployment in the …
