Grazing Management For Livestock, Free-Roaming Horses And Burros, And Resilience, Sherman R. Swanson

Human–Wildlife Interactions

Grazing management avoids overgrazing by allocating forage for livestock on the basis of animal unit months and managing wild and free-roaming horses (Equus caballus) and burros (E. asinus) to achieve and maintain an appropriate management level (AML) for each herd. Riparian green forage and water attracts cattle (Bos taurus) and equids when upland forage is brown. Key species that focus management for resilience to weather variation, fire, and floods are preferred forage plants for cattle and horses. They include riparian stabilizers such as densely rooted sedges and deep-rooted perennial grasses in sagebrush (Artemisia …

Exploring The Consistency Of Flow Regimes Within And Among Ecoregions Of The Southeastern United States, Frank Paul Braun Iv

College of Graduate Studies: Theses & Dissertations

Human manipulation of river systems has long been a known contributor to the loss of freshwater biodiversity. By accounting for environmental causes of hydrologic variation among rivers, we can better understand how ecoregion mediates flow regimes and forecast species that may be at risk. Presumably, natural variation associated with ecoregion boundaries exerts strong influence on flow regimes, and may mediate relationships between other features (e.g., land use, dam operations) and hydrology. However, such between-ecoregion variation is poorly investigated, particularly at fine spatial and temporal scales. I characterized 10 hydrologic metrics, representing the five key dimensions of the flow regime (magnitude, …

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. …

Screening H3 Histone Acetylation In A Wild Bird, The House Sparrow (Passer Domesticus), Daniella Ray

College of Graduate Studies: Theses & Dissertations

Epigenetic mechanisms are increasingly understood to have major impacts across ecology. However, one molecular epigenetic mechanism, DNA methylation, currently dominates the literature. A second mechanism, histone modification, is likely important to ecologically relevant phenotypes and thus warrants investigation, especially because molecular interplay between methylation and histone acetylation can strongly affect gene expression. There are a limited number of histone acetylation studies on non-model organisms, yet those that exist show that it can impact gene expression and phenotypic plasticity. Wild birds provide an excellent system to investigate histone acetylation, as free-living individuals must rapidly adjust to environmental change. Here, we screen …

Impact Of Road Infrastructures On The Abundance Of Common Chameleon Populations, Pablo García-Quevedo, Francisco Díaz-Ruiz, Antonio Román Muñoz, Jesús Duarte, Adrián Martín-Taboada, José-María García-Carrasco, Miguel Ángel Farfán

Human–Wildlife Interactions

The common chameleon (Chamaeleo chamaeleon) is a threatened species in Spain. The loss and transformation of their traditional habitats are among the main causes of its decline. Linear infrastructures, such as roads and highways, cause direct habitat loss, roadkill, and fragmentation of populations by acting as an artificial barrier. In this study, we investigated the potential effect of 2 high-speed road infrastructures in southern Spain on local populations of common chameleons. A total of 34 grids of 1x1 km were sampled, differentiating between grids without road presence (n = 17) and grids with road presence (n …

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 …

An Assessment Of Functional Characteristics In Macroinvertebrates And Fishes In The Lower Ogeechee River, Molly A. Mckeon

College of Graduate Studies: Theses & Dissertations

The southeastern United States is a hotspot for aquatic biodiversity; yet this region is also considered vulnerable to climate and land–use changes. The Ogeechee River is an unimpeded blackwater river in Georgia that drains into the Atlantic Ocean and a unique ecosystem due to the preservation of its natural state; Historically, research conducted in the river establishes a baseline for long-term ecological studies. The aim of this study is to compare aquatic macroinvertebrate and fish community composition data collected in 2014 to 2017 to a recently collected dataset from 2023 and document temporal changes. Water quality monitoring was performed throughout …

Grass Rejection By Capybaras Can Be Used As A Possible Strategy To Mitigate Road Accidents, André Luiz Gama Nogueira, Sérgio Luiz Gama Nogueira-Filho, Selene Siqueira Da Cunha Nogueira, Denis Sato, Natasha Camilo Maximiano Da Silva, Lilian Elgalise Techio Pereira, Michael Mendl, Adroaldo José Zanella

Human–Wildlife Interactions

Feeding management can be a good strategy for avoiding wildlife–vehicle collisions (WVCs), which are a worldwide concern. In this study, we aimed to identify grass species that capybaras (Hydrochoerus hydrochaeris) reject as feeding material. These species could be planted to make roadsides less attractive to capybaras and, consequently, decrease WVCs involving this species. We planted 3 grass species (Brachiaria decumbens cv. Basilisk, B. hybrid Mavuno, and Zoysia japonica) in 4 blocks, applying a randomized-complete blocks design. The first 2 species we assumed would be rejected, since some animals do not consume them due to their high …

Survival Of Translocated Coyotes In The Chicago Metropolitan Area, Usa, Charlotte R. Milling, Chris Anchor, Stanley D. Gehrt

Human–Wildlife Interactions

For nuisance animals, the general public perceives translocation to be a humane alternative to lethal control measures, but survival of translocated wildlife is often quite low due in part to increased movement post-release. Thus, for common species whose relocation generally serves a social rather than conservation purpose, translocation might not be correctly characterized when presented as nonlethal. We quantified release site fidelity and survival of coyotes (Canis latrans) fitted with very high frequency radio-collars and translocated within the Chicago Metropolitan Area, Illinois, USA, from 2000 to 2006. We also compared survival for 14 weeks post-collaring for our translocated …

Dust Management At An Active Construction Area Affects Monarch Distribution, Amy W. O'Donnell, Jeffery D. Sullivan, Carl R. Callahan, Peter C. Mcgowan, Diann J. Prosser

Human–Wildlife Interactions

The North American population of monarch butterflies (Danaus plexippus) is experiencing dramatic declines, necessitating investigations into challenges facing this species that can be resolved through management actions. For instance, dust made airborne by heavy equipment driving along a dirt road can settle on roadside vegetation, resulting in reduced use by monarchs. Dust accumulation on areas where floral nectaries such as leaves, stems, and flowers may be present could reduce the ability of pollinators, such as monarchs, to access nectar from flowering plants needed during migration. One such challenge was observed on Poplar Island, an island restoration project located in …

The Sewage Microbiome Dynamics Of Different Serving Neighborhoods In Charleston, Illinois, Sandra Chiamaka Okoye

Masters Theses

The complex microbial ecosystem within sewage systems holds significant implications for environmental and public health. Unlike studies on wastewater treatment plant microbiomes, upstream sewage systems have not been studied widely. This research investigated the dynamic sewage microbiome across diverse serving neighborhoods in Charleston, Illinois, encompassing residential, hospital, industrial, and university areas. Drawing upon recent advancements in microbiome research, the study aimed to unravel the spatial and temporal variations in microbial structures. Three times between June to December 2023 sewage samples were collected from manholes in the areas mentioned above. Community DNA was extracted and sequenced for the V4-V5 region of …

Leaf To Canopy Functional Resilience: Plant Physiological And Carbon Cycling Stability Following Disturbances, Lisa T. Haber

Theses and Dissertations

Ecological disturbances impact core ecosystem functions, including production and biogeochemical cycling, by precipitating changes in biodiversity, physical environmental variables, vegetation structure, and functional trait distributions. As disturbance patterns intensify and abruptly transition to novel regimes under global change, future trajectories of ecosystem functions, including carbon (C) uptake and storage, are uncertain. A more complete understanding of the mechanisms underpinning ecosystem stability (or ability to return to baseline functioning) following disturbance is needed to forecast future C cycling.

Replicated ecosystem-scale disturbance experiments, particularly when coupled with modeling, are required to rigorously test hypothesized trajectories of ecosystem structural and functional change following …

Hunting Types In North American Eocene And Oligocene Carnivores And Implications For Nimravid Extinction, Miguel Andres Castellanos

Graduate Research Theses & Dissertations

The late Eocene and Oligocene is traditionally seen as a time of great climactic shift, with open habitats beginning to appear and forests receding. This time period saw both the diversification and subsequent extinction of North American nimravids. The causes of the extinction of this early sabertooth group in the Arikareean remain unclear. One possibility for their decline is that nimravids were competitively disadvantaged in open habitats relative to contemporary, possibly more cursorial caniform predators. Here I analyze and compare the hunting styles of Eocene and Oligocene predators in correlation with their ecological implications via discriminant function analysis of the …

The Energetics Of Seasonality In Wild Diademed Sifaka (Propithecus Diadema): A Technical And Biological Validation Of Fecal Triiodothyronine Radioimmunassay, Casey Farmer

Graduate Research Theses & Dissertations

The energetic state of an animal has vital consequences for its fitness, but it can be difficult to detect through behavioral observations. The development of techniques to determine an animals’ energetic state non-invasively would allow conservation planners to rapidly assess the energy balance and conservation potential of individuals, groups, and populations. Thyroid hormones like triiodothyronine (T3) regulate and reflect metabolic state in mammals. T3 is a non-invasive biomarker that can be detected in feces and could potentially be used for this purpose. I perform the first validation of a commercially available T3 radioimmunoassay designed for humans on a wild strepsirrhine …

On The Ground And From Above: A Multi-Factor Analysis Of The Direct And Indirect Drivers Of Tallgrass Prairie Small Mammal Communities, Erin Rowland-Schaefer

Graduate Research Theses & Dissertations

Tallgrass prairies are among the most globally threatened ecosystems, with only one percent of the historical extent remaining in Illinois. Prairie restoration is an essential strategy to preserve biodiversity and reestablish threatened species. Practitioners use management tools to shift the landscape context of prairie restoration sites, such as prescribed fire and land cover change. Managers can also impact the landscape connectivity and edge proximity of certain areas through the use of mowed driving lanes. The effects of these factors on small mammals, which are central in tallgrass prairie food webs and relevant to human health and restoration success, are not …
