Towards Water Literacy: An Interdisciplinary Analysis Of Standards For Teaching And Learning About Humans And Water, Silvia‑Jessica Mostacedo‑Marasovic, Brooke Colleen Mott, Holly White, Cory T. Forbes

School of Natural Resources: Faculty Publications

Water is critical to sustain human existence. Water literacy involves understanding the interactions within and between natural and human dimensions of water systems to support informed decision-making, an important outcome for learners of all ages. It is therefore critical to foster water literacy in today’s global citizens, particularly through formal education. The purpose of this study, in tandem with a parallel study focusing on natural dimensions of water systems (Mostacedo-Marasovic et al., in press), is to examine water-related K-12 standards for teaching and learning about human dimensions of water systems to develop a comprehensive and transdisciplinary perspective on water education. …

Evaluating The Effectiveness Of Readiness Assurance Testing As Part Of Team-Based Ecology Instruction, Danielle Berger, Larkin Powell

School of Natural Resources: Faculty Publications

Readiness Assurance Testing (RAT) incorporates content recall, immediate feedback and peer instruction, three strategies known to enhance student learning, into a single classroom activity. While iRAT and tRAT assessments are promising instructional tools, they are time-intensive to administer.

1.Do iRAT/tRAT tests promote student retention of content better than other in-class activities, justifying the investment of instructional time? 2.Are iRAT/tRAT tests beneficial across the spectrum of academic performance?

• Students get a larger proportion of RAT questions correct on exams than other multiple choice questions (Table 1, RAT~MC Intercept), supporting the claim that this instructional technique provides better content-retention than other …

No Panacea Attractant For Wild Pigs (Sus Scrofa), But Season And Location Matter, Nathan P. Snow, Caitlin A. Kupferman, Michael J. Lavelle, Kim M. Pepin, Madeline H. Melton, Whitney J. Gann, Kurt C. Vercauteren, James C. Beasley

United States Department of Agriculture Wildlife Services: Staff Publications

Wild pigs (Sus scrofa) are a prolific invasive species throughout many regions of the world that cause extensive economic and environmental damage. Trapping is a common strategy for reducing their populations with baits (i.e., food) and attractants (e.g., scents) used to lure wild pigs into traps. However, there is little information on which scent attractants may attract wild pigs more readily and rapidly across regions and seasons. We examined 60 scent attractants for wild pigs that could be used to increase trapping success across three seasons (winter, spring, and fall) and in two geographic regions, including a warm …

Predation Thresholds For Reintroduction Of Native Avifauna Following Suppression Of Invasive Brown Treesnakes On Guam, Robert M. Mcelderry, Eben H. Paxton, Andre V. Nguyen, Shane R. Siers

United States Department of Agriculture Wildlife Services: Staff Publications

The brown treesnake (BTS) (Boiga irregularis) invasion on Guåhan (in English, Guam) led to the extirpation of nearly all native forest birds. In recent years, methods have been developed to reduce BTS abundance on a landscape scale. To help assess the prospects for the successful reintroduction of native birds to Guåhan following BTS suppression, we modeled bird population persistence based on their life history characteristics and relative sensitivity to BTS predation. We constructed individual-based models and simulated BTS predation in hypothetical founding populations for each of seven candidate bird species. We represented BTS predation risk in two steps: …

Conserving Endangered Black-Footed Ferrets: Biological Threats, Political Challenges, And Lessons Learned, Travis M. Livieri, Steven C. Forrest, Marc R. Matchett, Stewart Breck

United States Department of Agriculture Wildlife Services: Staff Publications

There may be few stories in the annals of wildlife management that are as dramatic as the near demise and comeback of the black-footed ferret (Mustela nigripes). Endemic only to North America, this charming little carnivore found only in the continent’s central grasslands was hardly known to science until the mid-20th century. By then, vast colonies of the prey it depended on for food and shelter, the prairie dog (Cynomys spp.), had been wiped out through disease (sylvatic plague) and an agricultural industry with little tolerance for burrowing and grazing rodents. At its low point, the species’ …

Species-Specific Responses To Landscape Features Shaped Genomic Structure Within Alaska Galliformes, Sarah A. Sonsthagen, Robert E. Wilson, Sandra L. Talbot

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Aim: Connectivity is vital to the resiliency of populations to environmental change and stochastic events, especially for cold-adapted species as Arctic and alpine tundra habitats retract as the climate warms. We examined the influence of past and current landscapes on genomic connectivity in cold-adapted galliformes as a critical first step to assess the vulnerability of Alaska ptarmigan and grouse to environmental change. We hypothesize that the mosaic of physical features and habitat within Alaska promoted the formation of genetic structure across species.

Location: Alaska, United States of America.

Taxa: Ptarmigan and Grouse (Galliformes: Tetraoninae).

Methods: We collected double digest restriction-site- …

Spatial And Temporal Variability Of Mercury In Upper And Lower Red Lake Walleye, Tyler Orgon

Biology Graduate Theses

Mercury is a global pollutant that is released into our environment by natural and anthropogenic processes resulting in extensive studies conducted on mercury cycling in aquatic ecosystems which has led to the issuance of human-health-based fish-consumption advisories. We examined total mercury concentrations in Walleye Sander vitreus from Upper and Lower Red Lakes, located in north central Minnesota, between 2019 and 2020. Upper and Lower Red Lake form a contiguous water body consisting of two large (483.1 and 665.6 km2, respectively) basins that are naturally connected by a 1.4 km-wide strait. Both basins are important fisheries for recreation, subsistence, and commercial …

Co-Producing A Shared Characterization Of Depredation In The Gulf Of Mexico Reef Fish Fishery: Comprehensive Report, James M. Drymon, Ana Osowski, Amanda Jargowsky, Matthew Ajemian, Angela Collins, Bryan Fluech, Steven Gray, Julie Lively, Steven Scyphers

CREC Publications

Depredation, defined as the partial or complete removal of a hooked fish by a non-target species, is a cryptic form of mortality that can affect the accuracy of stock assessments and species management efforts. Accounting for depredation is crucial to minimize uncertainty in stock assessment models and to obtain accurate and reliable fisheries catch data. If these interactions are frequent, failure to properly quantify this form of mortality can lead to the underestimation of reef fish population removals, inappropriate harvest recommendations, and stakeholder unrest. In recent years, depredation has escalated in the Gulf of Mexico (GoM) reef fish fishery. Although …

"Reeling In" Juvenile Sportfish Through Coastal Habitat Restoration: Population, Community, And Trophic Responses In The Indian River Lagoon, Florida, Jennifer Loch

Electronic Theses and Dissertations, 2020-2023

Coastal habitats provide crucial nursery habitat for predatory fishes, but they are in decline worldwide, impacting economically important fisheries. Habitat restoration can simultaneously mitigate the effects of habitat loss and benefit predators (e.g., sportfish), although this relationship is understudied. Here, the response of juvenile sportfish to oyster reef and living shoreline restoration is compared to controls in the Indian River Lagoon, Florida prior to and following restoration for up to three years through examination of community (diversity, assemblage), population (abundance), biometric (size, body condition), ontogenetic, and trophic (gut contents, stable isotopes) dynamics. Stable isotopes were used to quantify dietary history, …

Foot Injuries In Michigan, Usa, Gray Wolves (Canis Lupus), 1992–2014, Daniel J. O'Brien, Dean E. Beyer Jr., Erin Largent, Julie R. Melotti, Caitlin N. Ott-Conn, Donald H. Lonsway, Thomas M. Cooley, Robert Atkinson, Michelle Clayson, Kelly A. Straka

United States Department of Agriculture Wildlife Services: Staff Publications

The range of gray wolves (Canis lupus) in the contiguous US is expanding. Research and monitoring to support population recovery and management often involves capture via foothold traps. A population-level epidemiologic assessment of the effect of trap injuries on wolf survival remains needed to inform management. We describe the baseline rate, type, and severity of foot injuries of wolves born 1992–2013 in Michigan’s Upper Peninsula, evaluate the reliability of field-scoring trap-related injuries, and the effect of injuries on wolf survival. We assessed foot injuries by physical and radiographic exam at postmortem and/or time of capture for 351 wolves using the …

Olfactory Lures In Predator Control Do Not Increase Predation Risk To Birds In Areas Of Conservation Concern, Page Klug, Amy A. Yackel Adams, Robert N. Reed

United States Department of Agriculture Wildlife Services: Staff Publications

Context. Lethal control of predators is often undertaken to protect species of conservation concern. Traps are frequently baited to increase capture efficacy, but baited traps can potentially increase predation risk by attracting predators to protected areas. This is especially important if targeted predators can escape capture due to low trap success. Snake traps using live mouse lures may be beneficial if traps effectively remove snakes in the presence of birds and do not attract additional snakes to the area.

Aims. The present study evaluated whether mouse-lure traps in areas occupied by birds (simulated by deploying birdlure traps) could influence predation …

Wild Pig Removal Reduces Pathogenic Bacteria In Low-Order Streams, Sara A. Bolds, B. Graeme Lockaby, Latif Kalin, Stephen S. Ditchkoff, Mark D. Smith, Kurt Vercauteren

United States Department of Agriculture Wildlife Services: Staff Publications

Invasive wild pig populations have undergone enormous increases in the United States and particularly across the southern U.S. in recent years. High fecundity rates and abilities to adapt quickly to varied habitats have enabled pig populations to become entrenched and difficult to eliminate. The pigs cause many negative impacts on ecosystems including degradation of water quality through infusion of fecal contamination and other non-point source pollutants. Our goal was to determine the effects of pig removal on water quality in streams that were known to be significantly polluted by pig activity Bolds (J Environ Qual 50: 441–453, 2021). We compared …

Power In Numbers: An Abundance Of Small Corals Responsible For Storing Over Half Of The Carbon Stored By All Alaskan Primnoa Pacifica Deep-Sea Corals, Sylvie Alexander

Scripps Senior Theses

Gorgonian deep-sea corals (DSCs) are biologically linked to ocean carbon cycling converting ocean carbon to gorgonin and calcite in their skeletons. As such, gorgonian DSCs likely accumulate and store carbon in their skeleton throughout their lifespans, acting as carbon sinks on historic timescales. Yet, DSC carbon storage hasn’t been investigated to date. This study evaluates gorgonian DSC carbon storage capacity through an evaluation of the carbon stored by Alaskan Primnoa pacifica corals. The development of a model relating coral height to biomass in specimens with this data available was used to determine biomass values in a suite of Alaskan P. …

Review Of Spiders Of North America, By Sarah Rose, Michael L. Draney

The Prairie Naturalist

A field guide to spiders, the dominant terrestrial predator group, has long been a desire for North American naturalists, biologists, and spider fans, but not surprisingly, the first “real” field guide has been a long time coming. The diversity of spiders, with over 50,000 known species globally (World Spider Catalog 2022) and around 4,000 in North America north of Mexico (Rose 2022), is well beyond the diversity of more traditional field guide targets such as birds (about 1,000 species north of Mexico; American Birding Association 2022) or butterflies (about 725 species north of Mexico; North American Butterfly Association 2022). Also, …

Review Of Methods For Ecological Research On Terrestrial Small Mammals, By Robert Mccleery, Lynda R. Lafond

The Prairie Naturalist

Small mammals are used in ecological studies throughout the world, yet the subject has lacked a clear reference that included upto- date methods pertaining to passive detection, molecular, and statistical approaches. In Methods for Ecological Research on Terrestrial Small Mammals, McCleery and his coauthors build on previous research references (Braun 2005, Sutherland 2006, Krebs 2014, Silvy 2020) and present methodologies specific to the study of small mammals that are applicable globally. Written as an asset for novice and experienced small mammal researchers alike, Methods for Ecological Research on Terrestrial Small Mammals is organized in a logical format, providing readers …

Second Twenty-Five Year Index: Volumes 26–50, 1994–2018, Jane E. Austin

The Prairie Naturalist

The first 50 years of the Prairie Naturalist reside on the shelves of libraries and personal collections. The articles and notes published over those years provide invaluable knowledge about Great Plains biota, communities, conservation, and landscape ecologies. Awareness of the wealth of information in those 50 print volumes has been limited, relying on references from other published papers or the limited number of articles that have been made available online by authors. This index serves as resource for individuals to digitally tap into the information published since 1994. This index, together with the first 25-year index, serves to complement the …

Plague Risk In The Western United States Over Seven Decades Of Environmental Change, Colin J. Carlson, Sarah N. Bevins, Boris V. Schmid

United States Department of Agriculture Wildlife Services: Staff Publications

After several pandemics over the last two millennia, the wildlife reservoirs of plague (Yersinia pestis) now persist around the world, including in the western United States. Routine surveillance in this region has generated comprehensive records of human cases and animal seroprevalence, creating a unique opportunity to test how plague reservoirs are responding to environmental change. Here, we test whether animal and human data suggest that plague reservoirs and spillover risk have shifted since 1950. To do so, we develop a new method for detecting the impact of climate change on infectious disease distributions, capable of disentangling long-term trends (signal) and …

A Gis Analysis Of Potential Wetland Mitigation Opportunities In The Brandywine Creek Watershed, Chester County, Pennsylvania, Shannon Ryan

West Chester University Master’s Theses

Wetlands provide innumerous functions and values that are beneficial to both the natural environment and economic systems. Historically these habitats have suffered significant losses and it is crucial to preserve existing wetlands and plan for future restoration opportunities. This research examines six sub-watersheds within the Brandywine Creek watershed within Chester County, Pennsylvania to determine where potential wetland mitigation opportunities occur. Using a Geographic Information Systems (GIS) analysis, three wetland characteristics including watercourse locations, existing National Wetlands Inventory (NWI) wetlands, and hydric soils were mapped throughout each of the watersheds. Areas of agricultural easements and steep slopes were used to exclude …
