People, Place, And Planet: Global Review Of Use-Inspired Research On Water-Related Ecosystem Services In Urban Wetlands, Jason Sauer, Heejun Chang

Geography Faculty Publications and Presentations

With climate change and urbanization, city planners and developers have increasing interest and practice in constructing, restoring, or incorporating wetlands as forms of green infrastructure to maintain water-related ecosystem services (WES). We reviewed studies that valued in functional or monetary units the water regulation and purification services of urban wetlands around the globe. We used the adaptive management cycle (AMC) as a heuristic to determine the step that a study would represent in the AMC, the connections between the cycle steps that were used or considered, and the stakeholders involved. Additionally, we identified the social, ecological, and/or technological dimension(s) of …


Characterization Of The Long-Distance Dispersal Kernel Of White-Tailed Deer And Evaluating Its Impact On Chronic Wasting Disease Spread In Wisconsin, Mennatallah Gouda Dec 2023

Characterization Of The Long-Distance Dispersal Kernel Of White-Tailed Deer And Evaluating Its Impact On Chronic Wasting Disease Spread In Wisconsin, Mennatallah Gouda

All Graduate Theses and Dissertations, Fall 2023 to Present

Chronic Wasting Disease (CWD) is a fatal, untreatable neurodegenerative disease that infects deer and related species. It is highly contagious and caused by abnormal malfunction and assembly of normal cellular proteins into aggregation-prone proteins. The Centers for Disease Control and prevention report that the prevalence of CWD in free-ranging deer in the US is still relatively low. However, in several states the infection rates exceed 1 deer in 10. Deer may uptake CWD from direct interaction with infected individuals or from the environment. Infected individuals shed CWD into the environment through feces, urine, saliva or carcasses, and long-distance dispersal of …

Linking Microbial Community Assembly In Flowers With Function Under Diverse Environmental Conditions: A Case Study Involving Erwinia Amylovora, Christopher Skylar Mcdaniel

All Graduate Theses and Dissertations, Fall 2023 to Present

Fire blight, a devastating disease of pome fruit trees caused by the bacterium Erwinia amylovora, can cause millions of dollars in losses for producers each year around the globe. Management approaches that involve use of antibiotics, such as streptomycin, can be effective; although concerns exist over pollinator and crop health when using them regularly. Recently, there have been developments that allow for biological agents such as microbes to curtail fire blight infection. These agents work by competing with Erwinia for resources or space, producing antibacterial compounds, or even killing Erwinia cells on contact. Unfortunately, these agents do not yet …


Inundated Vegetation Response To Ongoing Restoration And Its Impacts On Fish Community Structure, Emmanuel J. May Dec 2023

Inundated Vegetation Response To Ongoing Restoration And Its Impacts On Fish Community Structure, Emmanuel J. May

All Graduate Theses and Dissertations, Fall 2023 to Present

Shallow lake ecosystems and their associated wetland habitats globally are subject to non-native species introductions, nutrient loading, and water level fluctuations, each of which can decrease vegetated habitat availability, exposing vulnerable native aquatic species to predation. Managers are frequently tasked with mitigating native species declines by restoring vegetation considered crucial for their survival. However, restoring vegetation can be challenging in the presence of multiple stressors, requiring managers to assess the relative importance of the different stressors limiting vegetation recovery.

Utah Lake is a large shallow lake subject to multiple stressors and has shifted from a mesotrophic lake with abundant aquatic …

Phenology Of The Invasive Balsam Woolly Adelgid, Adelges Piceae (Ratz.) (Hemiptera: Adelgidae), On Subalpine Fir In Northern Utah, Elizabeth L. Rideout

All Graduate Theses and Dissertations, Fall 2023 to Present

Balsam woolly adelgid (BWA) is an invasive true fir pest in North America. Native to Europe, BWA was first discovered in Utah attacking subalpine fir in 2017. Recent BWA-caused subalpine fir mortality in northern Utah has prompted the need for baseline biological research to support pest management. Small-bodied and blending easily with its environment, BWA is a challenging pest to detect and study. Phenology, or the timing and characteristics of life stages through the year, of BWA varies depending on elevation and climate and is unstudied in Utah. This research focuses on defining aspects of BWA’s phenology, including the number …


The Blueberry Gall Midge Complex And Its Specialist Parasitoids, Monique Michele Raymond Dec 2023

The Blueberry Gall Midge Complex And Its Specialist Parasitoids, Monique Michele Raymond

Master's Theses and Capstones

The cosmopolitan blueberry gall midge complex causes serious damage to the terminal vegetation of blueberry plants. The nature of their infestation, paired with prolonged periods of abundance, requires an integrated pest management approach. Of all known parasitoids present in the system, members of the subfamily Platygastrinae are the only oligophagous clade specialized against true gall midges. In this study, we present the results of blueberry gall midge and platygastrid surveys in high- and low-bush blueberry crops in the northeastern and southeastern United States, along with an identification key, with emphasis on blueberry parasitoid Synopeas species to facilitate their identification.

The Endoparasite Fauna Of Mesopredatory Mesopelagic Teleosts, Alexander U. Rayburn

All HCAS Student Capstones, Theses, and Dissertations

The ecology of the mesopelagic zone is an understudied area of the open ocean, with few diet studies even for dominant fish species. Since endoparasites are generally transmitted trophically, descriptions of the parasite communities within fishes can often provide additional insights on food web interactions. This project assesses the endoparasite faunal community of mesopredatory mesopelagic teleosts to better understand mesopelagic food webs in the South Atlantic Bight. Fishes in the Families Alepisauridae (lancetfishes), Gempylidae (snake mackerels), Bramidae (pomfrets), and Scombrolabracidae (longfin escolar) are frequent bycatch in the pelagic longline fishery targeting swordfish Xiphias gladius and thunnid tunas, yet the ecology …

Evaluating Functional Diversity As Potential Early-Warning Indicator Of Rangeland Degradation, L.-M. Schwarz, C. P. Carmona, M. C. Bilton, F. Munyebvu-Chambara, K. Behn, A. Linstädter Nov 2023

Evaluating Functional Diversity As Potential Early-Warning Indicator Of Rangeland Degradation, L.-M. Schwarz, C. P. Carmona, M. C. Bilton, F. Munyebvu-Chambara, K. Behn, A. Linstädter

IGC Proceedings (1977-2023)

Droughts and overgrazing play a crucial role in the degradation of semi-arid rangelands. This is evident in the loss of palatable long-lived grass species and bush encroachment. Early warning indicators are needed to mitigate long-term degradation and decline in essential forage provision. Functional diversity provides valuable information on ecosystem health. However, functional diversity indices have not yet been tested regarding their applicability as early warning indicators, revealing non-linear threshold behaviour. We therefore examined the following questions: (1) How do functional diversity indices respond to grazing pressure? (2) Does land tenure affect the relationship between functional diversity and grazing pressure? (3) …

All Works

The intricate relationship between COVID-19 and diabetes has garnered increasing attention within the medical community. Emerging evidence suggests that individuals with diabetes may experience heightened vulnerability to COVID-19 and, in some cases, develop diabetes as a post-complication following the viral infection. Additionally, it has been observed that patients taking cough medicine containing steroids may face an elevated risk of developing diabetes, further underscoring the complex interplay between these health factors. Based on previous research, we implemented deep-learning models to diagnose the infection via chest x-ray images in coronavirus patients. Three Thousand (3000) x-rays of the chest are collected through freely …


The Green Encounters: “Common Good” Narrative And Community Struggle In Halimun Salak Coridor, West Java, Sulastri Sardjo Oct 2023

The Green Encounters: “Common Good” Narrative And Community Struggle In Halimun Salak Coridor, West Java, Sulastri Sardjo

Antropologi Indonesia

Since the colonial era of the East Indies, multiple ruling regimes have promoted a certain narrative to utilize the forests on Mount Halimun Salak for nature preservation and profit accumulation. Existing studies of the designation of Halimun Salak as a conservation area have shown that such an establishment led to conflicts over land and livelihoods with the surrounding communities and local farmers. Complementing these studies, my qualitative research in the Halimun Salak Corridor (HSC) highlights that the “common good” narrative promoted by conservation programs has not benefited people’s livelihoods. Conversely, the expansion of conservation area through HSC has further restricted …


Mesophotic Coral Bleaching Associated With Changes In Thermocline Depth, Clara Diaz, Nicola L. Foster, Martin J. Attrill, Adam Bolton, Peter Ganderton, Kerry L. Howell, Edward Robinson, Phil Hosegood Oct 2023

Mesophotic Coral Bleaching Associated With Changes In Thermocline Depth, Clara Diaz, Nicola L. Foster, Martin J. Attrill, Adam Bolton, Peter Ganderton, Kerry L. Howell, Edward Robinson, Phil Hosegood

School of Biological and Marine Sciences

As global temperatures continue to rise, shallow coral reef bleaching has become more intense and widespread. Mesophotic coral ecosystems (30–150 m) reside in deeper, cooler, water and were thought to offer a refuge to shallow-water reefs. Data now show that mesophotic coral ecosystems instead have limited connectivity with shallow corals but host diverse endemic communities. Given their extensive distribution and high biodiversity, understanding their susceptibility to warming oceans is imperative. In this multidisciplinary study we show evidence of coral bleaching at 90 m in the Indian Ocean, despite the absence of shallow-water bleaching. The bleaching was associated with sustained thermocline …

Metrics Matter: Multiple Diversity Metrics At Different Spatial Scales Are Needed To Understand Species Diversity In Urban Environments, Kathryn A. O'Shaughnessy, Antony M. Knights, Stephen J. Hawkins, Mick E. Hanley, Paul Lunt, Richard C. Thompson, Louise B. Firth

School of Biological and Marine Sciences

Worldwide, natural habitats are being replaced by artificial structures due to urbanisation. Planning of such modifications should strive for environmental net gain that benefits biodiversity and ecosystems. Alpha (α) and gamma (γ) diversity are often used to assess ‘impact’ but are insensitive metrics. We test several diversity measures across two spatial scales to compare species diversity in natural and artificial habitats. We show γ-diversity indicates equivalency in biodiversity between natural and artificial habitats, but natural habitats support greater taxon (α) and functional richness. Within-site β-diversity was also greater in natural habitats, but among-site β-diversity was greater in artificial habitats, contradicting …

D-Shaped Nematode Eggs In The Feces Of Rangifer Tarandus: A Story In Pictures, Olga A. Loginova Oct 2023

D-Shaped Nematode Eggs In The Feces Of Rangifer Tarandus: A Story In Pictures, Olga A. Loginova

MANTER: Journal of Parasite Biodiversity

D-shaped nematode eggs in the feces of Rangifer tarandus are expected to be oxyurid nematodes (Nemata: Oxyurida) of the genus Skrjabinema. The species S. tarandi is considered species-specific for this host. There is no consensus regarding the cross-infection of reindeer and sheep with S. ovis and S. tarandi. The drawings proposed by descriptors complicate differential diagnostics. Micrographs of S. tarandi eggs obtained via light microscopy and scanning electron microscopy as well as photographs of S. ovis eggs and drawings made on their basis are proposed to confidently distinguish between representatives of these two species, taking into account morphometric data. Thus, …
