The Influence Of Land Use On The Pollen Diet Of Honey Bee (Apis Mellifera) Colonies In Ellis County, Kansas, Ryan Engel

Master's Theses or Doctor of Nursing Practice

Pollinators are integral to plant ecology as well as to worldwide food availability and security. Understanding how human-driven land use change impacts the nutrition of managed honey bees is important in pollinator conservation efforts and can contribute towards combating recent pollinator declines. The objective of this study was to determine sources of forage for honey bees across different land use types in Ellis County, Kansas, through pollen analysis and taxonomic identification. Replicate study colonies were placed in three separate land use types: Urban, Cropland, or Native/Semi-native prairie. Pollen was sampled every 7 to 14 days throughout a growing season (April …

Protecting Biodiversity On National Forests: The Evolution And Implementation Of Forest Planning Regulations, Anna Wearn

Graduate Student Theses, Dissertations, & Professional Papers

In 2012, the U.S. Forest Service (USFS) promulgated new forest planning regulations that significantly altered national forest management. One of the most controversial and important advancements was the inclusion of what were meant to be stronger biodiversity protections. An analysis of USFS’s rationale in revising the biodiversity regulations provides insights into how to interpret the substantively and procedurally new ecosystem and species protections. Examining this regulatory history reveals three key changes to the manner in which national forests are required to manage and monitor biodiversity: 1) a greater reliance on science to inform planning, 2) a new emphasis on ecological …

Temperate Eurasian Origins Of Hawaiian Chenopodium (Amaranthaceae) Plus Description Of A New Species Endemic To Moloka‘I, Jason T. Cantley, Angela J. Mcdonnell, J Branson, S R. Long, W Garnett, Christopher T. Martine

Faculty Journal Articles

Chenopodium taxa of Hawai‘i are tetraploids distinguished from other members of the circumglobally distributed genus by minute morphological characters. Because of these reasons, the geographic origin of Hawaiian Chenopodium has remained unclear. Across the Hawaiian Archipelago, Chenopodium taxa are morphologically variable and grow in highly disparate xeric habitats, especially in terms of precipitation, temperature, wind, salt spray, and solar irradiation. Habitats include dry subalpine shrublands, sandy beach strand of atolls in the Northwest Hawaiian Islands, dry forests, and precipitously tall sea cliffs of northwestern Moloka‘i. From the Moloka‘i sea cliffs, which are battered by high energy winds, salt spray, and …

Landscape Ecology And Population Genomics Of Two Sympatric Pitviper Species Across A Fragmented Appalachian Landscape, Thomas Maigret

Theses and Dissertations--Biology

Understanding the link between landscape patterns and ecological and evolutionary processes is an important prerequisite for informed wildlife conservation and management, especially in rapidly changing landscapes. Until recently, the inaccessibility of spatial and genomic data sets of sufficient resolution limited our ability to incorporate the impacts of landscape patterns into predictions of ecological and environmental outcomes. In this dissertation, I utilized several high-resolution spatial and genomic data sets to address ecological questions in a rapidly fragmenting landscape in southeastern Kentucky. Overall, my results indicate that large-scale surface coal mining is causing widespread homogenization of landforms, resulting in a uniquely permanent …

Diet Of A Recently Reintroduced River Otter (Lontra Canadensis) Population In Taos County, New Mexico, Gabriela Alexandra Wolf-Gonzalez

Theses and Dissertations--Forestry and Natural Resources

North American river otters (Lontra canadensis), native to every U.S. state and Canada, experienced extensive population decreases and range reduction until the mid-20th century as a result of overexploitation and habitat loss during European colonization. The last known river otter in New Mexico was killed on the Gila River in 1953, although unverified reports continued thru 2008. After a nearly 60-year absence from New Mexico, 33 adult river otters were reintroduced to the Rio Pueblo de Taos in the northern part of the state between 2008-2010; however, they were not subsequently monitored or studied. I characterized diet of …

Livestock-Wildlife Dynamics And Subsequent Human Responses In Marginalized Communities Within Mexico’S Nationally Protected Areas, Deanna Seil

Dissertations, Master's Theses and Master's Reports

Entering the planet’s sixth mass-extinction, monitoring biodiversity and the factors which affect it is of the utmost importance. This study on the interaction of humans and their livestock with wildlife, and the impact of this interaction on wildlife conservation, took place in Santiago Coatepec, located within the Tehuacán-Cuicatlán Biosphere Reserve in Mexico. Wildlife interactions with livestock may depend upon species, season, ecological characteristics of the area, and livestock management practices. Using camera traps, field data, and interview data, I quantified livestock impact on wildlife behavior and community beliefs. Over two years, camera traps at 18 stations recorded 709 wildlife videos …

Species Conservation & Recovery Through Adequate Regulatory Mechanisms, Sandra B. Zellmer, Sam J. Panarella, Oliver Finn Wood

Faculty Journal Articles & Other Writings

The world is experiencing its sixth episode of mass extinction of life. In rhetoric typically used by bloggers rather than scientists, the National Academy of Sciences reports that this "biological annihilation" is more dire than previously believed,' and that the decimation of biodiversity and of the ecosystem services resulting from it is nothing less than a "frightening assault on the foundations of human civilization."2

Unlike previous episodes of mass extinction, this one is caused by human overpopulation, overconsumption, and anthropogenic climate change. The United States has been a world conservation leader for over a century, but its commitment to supporting …

Black Bear, Jimmy D. Taylor, James P. Phillips

Wildlife Damage Management Technical Series

The American black bear (Ursus americanus, Figure 1) is a challenging species for wildlife agencies to manage due to its size, intelligence, extensive range, food habits, and adaptability, as well as societal views. In North America alone, agencies receive more than 40,000 complaints about black bear annually. Black bears are known as ‘food-driven’ animals, meaning most conflicts result from a bear’s drive to meet its nutritional needs. Not surprisingly, an overwhelming proportion of conflicts are related to their use of anthropogenic (human) food sources, such as garbage, bird food, and crops. Understanding what drives human-bear conflict is the first part …

Wildlife Health Systems, Lee Skerratt

Animal Sentience

Wildlife health systems aim to ensure that all animal life is healthy and resilient. They protect biodiversity and ecosystem services and ensure that the risk of spillover of pathogens is mitigated. These systems are flexible, multidisciplinary and cross-sectorial. They can manage a variety of threats to life that arise in different communities and cultures. Very small investments are required to ensure that wildlife health systems function effectively.

Vertebrate Natural History Notes From Arkansas, 2020, C. Renn Tumlison, Matt Connior, Blake Sasse, Henry Robison, Stan Trauth, S Higdon, L Baer, Z. Baer, R. Stinson, D. Carson, T. Inebnit, L. Lewis, Roger Perry, Ron Redman

Journal of the Arkansas Academy of Science

Smaller details of natural history often go undocumented to science if those details are not parts of larger studies, but small details can provide insights that lead to interesting questions about ecological relationships or environmental change. We have compiled recent important observations of distribution and reproduction of fishes and mammals. Included are new distributional records of mammals, and observations of reproduction in several mammals for which few data exist in Arkansas. A rare record of the Long-tailed weasel, a special of special concern in Arkansas, is documented from Newton Co. We also provide evidence that Seminole bats likely reproduce in …

Spatial And Temporal Genetic Structure Of Winter-Run Steelhead (Oncorhynchus Mykiss) Returning To The Mad River, California, Steven R. Fong

Cal Poly Humboldt theses and projects

Distinct populations of steelhead in the wild are in decline. The propagation of steelhead in hatcheries has been used to boost population numbers for recreational fisheries and for use in conservation. However, hatchery breeding practices of steelhead can result in changes in genetic structure. I investigated the genetic structure of winter-run steelhead (Oncorhynchus mykiss) returning to the Mad River, California, where a hatchery has been used enhance production for recreational fisheries since 1971. Genetic variability in Mad River steelhead was evaluated using 96 single nucleotide polymorphisms (SNPs) among 4203 individuals, including the Mad River and nearby locations, and …

Fungi were collected in each of the above regions, analyzed morphologically, and compared to the literature on Amanita diversity worldwide. All species addressed herein are given full formal taxonomic descriptions including complete macro- and microscopic character profiles, habit, habitat, and distribution. Phylogenetic assessments using ribosomal DNA and protein coding genes are provided for Guiana Shield taxa, and sequence data for two non-protein coding regions, the …

Challenging Our Conception Of Wildness, Elodie Massiot

Animal Sentience

Baker & Winkler (2020) point out the entanglement among free-living elephants, captive elephants, and humans in the elephant tourism industry. Where all living beings – captive and free-living – are more or less affected by human presence or activity, the binary notion of wild and captive, and in situ and ex situ conservation, becomes inadequate. B&W challenge our concept of wildness – and hence of rewilding – and our level of intervention in this wildness of which we are a component.

Acoustic Analysis Of Nomascus Gibbon Songs As A Potential Measure Of Current Health Status, Caroline Rowley

All Master's Theses

Post-release monitoring is vital to the rehabilitation process. Gibbons offer a unique challenge, as they are notoriously difficult to follow through the forest, but their duets offer a non-invasive window into their lives. The aim of this project is to create a method that will evaluate the health of rehabilitated and released gibbons through acoustic analyses. Gibbon duets are in part genetically determined, but learning may play a role in song development. Additionally, songs may indicate resource holding potential, and are vital to acquiring mates and producing offspring. Captive-raised gibbons are often denied the experience of co-singing with their parents, …

Diversity Analysis Of Soil Fungus Communities In Disturbed, Nursery, And Mature Forest Conditions, Dana Whitmore

All Master's Theses

Populations of soil fungi were examined in Derby Canyon Natives, Coeur d’Alene Forest Service nursery, Swamp Lake, and the Keechelus Lake wildlife overcrossing soils. All sampling sites were connected by their relation to the revegetation and native soil plug inoculation of the wildlife overpass. This study was an effort to describe soil fungi communities present on the overpass before plant introduction, those that plants would be bringing in their pots, and the fungi that could be introduced via soil plug transplantation. DNA was extracted from soil samples, then sequenced using next-generation sequencing methods, allowing for the analysis of species richness …

Ecological And Genetic Connectivity Of Shrews (Sorex Spp.) Across Interstate-90 In The Washington Cascade Range, Jordan Ryckman

All Master's Theses

Roads negatively affect wildlife by degrading and fragmenting habitat. The I-90 Snoqualmie Pass East project was established to improve traffic safety for both humans and wildlife. Here, the Washington State Department of Transportation is constructing wildlife crossing structures to increase ecosystem connectivity as part of this project. The goal of my study was to investigate shrews – very small mammals with presumably low mobility and dispersal capacity – at sites on the eastern slopes of the Cascade Range where wildlife crossing structures will be built in the future. My main objectives were to verify shrew species composition, assess population genetic …

Game Theory And Artificial Intelligence In Just Preservation, David L. Dowe, Nader Chmait

Animal Sentience

We humans can show presumption, arrogance and many dubious traits. By virtue of being land-dwelling, dexterous, relatively intelligent, and having good communication hardware and (good) fortune, we have for recent millennia largely had dominion of our planet. Yet humans often do not treat themselves (let alone other species) particularly well. Treves et al.’s idea of a multispecies justice system — not “prioritizing humans” but “finding practical ways to work within human systems” — invites consideration.

Just Preservation, Trusteeship And Multispecies Justice, Francisco J. Santiago-Ávila, Adrian Treves, William Lynn

Animal Sentience

We are grateful to all the commentators who engaged with our target article. Some commentators have offered important insights into our proposed design and methods for legally intervening on behalf of futurity. Others have focused on theoretical considerations central to our proposal for multispecies justice and trusteeship. All have inspired modifications and further elaboration of our initial proposal. In this Response, we engage with the commentaries, integrating their suggestions, striving for convergence and complementarity, but also discussing points of divergence with our proposed framework where necessary. There is substantial overlap in the points of view of the three co-authors, but …

Efficient Coi Barcoding Using High Throughput Single-End 400 Bp Sequencing, Chentao Yang, Yuxuan Zheng, Shangjin Tan, Guanliang Meng, Wei Rao, Caiqing Yang, David G. Bourne, Paul A. O'Brien, Junqiang Xu, Sha Liao, Ao Chen, Xiaowei Chen, Xinrui Jia, Ai-Bing Zhang, Shanlin Liu

Harold W. Manter Laboratory of Parasitology: Library Materials

Background

Over the last decade, the rapid development of high-throughput sequencing platforms has accelerated species description and assisted morphological classification through DNA barcoding. However, the current highthroughput DNA barcoding methods cannot obtain full-length barcode sequences due to read length limitations (for example, a maximum read length of 300 bp for the Illumina’s MiSeq system), or are hindered by a relatively high cost or low sequencing output (e.g. a maximum number of eight million reads per cell for the PacBio’s SEQUEL II system).

Results

Pooled cytochrome c oxidase subunit I (COI) barcodes from individual specimens were sequenced on the …

Harold W. Manter Laboratory of Parasitology: Library Materials

Natural history collections are leading successful large-scale projects of specimen digitization (images, metadata, DNA barcodes), thereby transforming taxonomy into a big data science. Yet, little effort has been directed towards safeguarding and subsequently mobilizing the considerable amount of original data generated during the process of naming 15,000–20,000 species every year. From the perspective of alpha-taxonomists, we provide a review of the properties and diversity of taxonomic data, assess their volume and use, and establish criteria for optimizing data repositories. We surveyed 4,113 alpha-taxonomic studies in representative journals for 2002, 2010, and 2018, and found an increasing yet comparatively limited use …

Energy Development And Production In The Great Plains: Implications And Mitigation Opportunities, Jacqueline P. Ott, Bruce B. Hanberry, Mona Khalil, Mark W. Paschke, Max Post Van Der Burg, A.J. Prenni

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Energy is an integral part of society. The major US energy sources of fossil fuels (coal, oil, natural gas); biofuels (ethanol); and wind are concentrated in grassland ecosystems of the Great Plains. As energy de- mand continues to increase, mounting pressures will be placed on North American grassland systems. In this review, we present the ecological effects of energy development and production on grassland sys- tems. We then identify opportunities to mitigate these effects during the planning, construction, and pro- duction phases by using informed methodology and improved technology. Primary effects during energy development include small- and large-scale soil disturbance …

Temporospatial Shifts In Sandhill Crane Staging In The Central Platte River Valley In Response To Climatic Variation And Habitat Change, Andrew J. Caven, Emma M. Brinley Buckley, Kelsey C. King, Joshua Wiese, David M. Baasch, Greg D. Wright, Mary Harner, Aaron T. Pearse, Matt Raabe, Dana Varner, Brice Krohn, Nicole Arcilla, Kirk D. Schroeder, Kenneth F. Dinan

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Over 80% of the Mid-Continent Sandhill Crane (Antigone canadensis) Population (MCP), estimated at over 660,000 individuals, stops in the Central Platte River Valley (CPRV) during spring migration from mid-February through mid-April. Research suggests that the MCP may be shifting its distribution spatially and temporally within the CPRV. From 2002 to 2017, we conducted weekly aerial surveys of Sandhill Cranes staging in the CPRV to examine temporal and spatial trends in their abundance and distribution. Then, we used winter temperature and drought severity measures from key wintering and early migratory stopover locations to assess the impacts of weather patterns …

Host Relationships And Geographic Distribution Of Species Of Blanchard, 1848 (Onchoproteocephalidea, Onchobothriidae) In Elasmobranchs: A Metadata Analysis, Francisco Zaragoza-Tapia, Griselda Pulido-Flores, Scott L. Gardner, Scott Monks

Scott L. Gardner Publications

Species of Acanthobothrium have been documented as parasites of the spiral intestine of elasmobranchs. Results of a metadata analysis indicate that 114 species of elasmobranchs have been reported as hosts of 200 species of Acanthobothrium. The metadata analysis revealed that 3.7% of species of sharks and 14.9% of species of rays that have been reported as hosts to date; some species are parasitized by more than one species of Acanthobothrium. This work provides a Category designation, as proposed by Ghoshroy and Caira (2001), for each species of Acanthobothrium. These Category designations are a tool to facilitate comparisons …

More Than Meets The Eye: A Taxonomic Revision Of The Nearctic Species In The Eye-Gnat Genus Amiota Loew (Diptera: Drosophilidae), Lance E. Jones

Dissertations and Theses

Thorough biotic inventories are still needed even in families as seemingly well-studied as fruit flies (Diptera: Drosophilidae). Drosophilidae have had an outsize effect on the history of biology because of their pivotal role in the study of genetics, development, and evolution. Even with more than a century of intensive study, large gaps remain in our understanding of diversity in this fly family, including well-studied areas such as North America. This thesis presents a taxonomic revision of the Nearctic species of the genus Amiota Loew. Twenty-three species are identified as being new to science for publication at a later date. This …

Small Mammal Communities In Grasslands At The Grand Forks Air Force Base, North Dakota, Usa, Lynda R. Lafond, Elizabeth H. Rave, Kathryn A. Yurkonis

The Prairie Naturalist

Small mammals are important in grasslands but are often overlooked in management and reconstruction efforts. We sampled small mammals in three sites on the Grand Forks Air Force Base (GFAFB) located in central Grand Forks County, North Dakota, USA. The study sites varied in their management history and represented the three major types of grasslands (reconstructed prairie, old field, and hay field) within Grand Forks County. We captured 463 individuals of six species with Sherman live traps in summer (June, July, August) 2014 and 2015. We captured the most individuals and species (295 individuals of 5 species), including all shrews …

Wood Frogs (Rana Sylvatica) In Southwestern Roberts County And Western Grant County, South Dakota, Dennis R. Skadsen, Drew R. Davis

The Prairie Naturalist

Historically, only six records of Wood Frogs (Rana sylvatica) existed from South Dakota, all represented by museum specimens. A single specimen was collected from Hartford Beach on Big Stone Lake, Roberts County in 1922 (National Museum of Natural History, Smithsonian Institution [USNM] 65452) and five Wood Frogs were collected near the outlet of Blue Dog Lake, Day County in 1929 (USNM 312618– 312622; Fig. 1). After the 1920s, no other Wood Frogs were reported in South Dakota for the next six decades, and the species was presumed extirpated. Over (1923, 1943) reported the species was common in the …
