Soil Resilience And Arbuscular Mycorrhizal Fungi: How Fungi Can Inform Climate Change Mitigation And Adaptation In Maya Milpa Management, Courtney Mathers

Electronic Theses and Dissertations

In Mexico’s state of Yucatán, climate change impacts like prolonged and less predictable dry season length are manifesting as threats to agricultural production and food security. Nearly two thirds of Yucatán’s population is indigenous, many of whom live in rural communities that rely on rainfed subsistence agriculture (INEGI 2015). Ensuring sufficient food production in the face of climate change relies on the quality of agricultural soils. With both mismanagement of agricultural soils and climate change posing as threats to food production in Mexico, soil management practices that increase a soil quality should be identified and promoted. The primary objective of …

Chapman, Jonathan D. Coop, Paula J. Fornwalt, Nathan S. Gill, Brian J. Harvey, Ashley E. Hoffman, Katharine C. Kelsey, Dominik Kulakowski, Daniel C. Laughlin, Jenna E. Morris, José F. Negrón, Katherine M. Nigro, Gregory S. Pappas, Miranda D. Redmond, Charles C. Rhoades, Monique E. Rocca, Zoe H. Schapira, Jason S. Sibold, Camille S. Stevens-Rumann, Thomas T. Veblen, Jianmin Wang, Xiaoyang Zhang, Sarah J. Hart

Geography

Amplified by warming temperatures and drought, recent outbreaks of native bark beetles (Curculionidae: Scolytinae) have caused extensive tree mortality throughout Europe and North America. Despite their ubiquitous nature and important effects on ecosystems, forest recovery following such disturbances is poorly understood, particularly across regions with varying abiotic conditions and outbreak effects. To better understand post-outbreak recovery across a topographically complex region, we synthesized data from 16 field studies spanning subalpine forests in the Southern Rocky Mountains, USA. From 1997 to 2019, these forests were heavily affected by outbreaks of three native bark beetle species (Dendroctonus ponderosae, Dendroctonus rufipennis and Dryocoetes …

The Influence Of Burn Severity On Post-Fire Spectral Recovery Of Three Fires In The Southern Rocky Mountains, Jaclyn Guz, Florencia Sangermano, Dominik Kulakowski

Geography

Increased wildfire activity and altered post-fire climate in the Southern Rocky Mountains has the potential to influence forest resilience. The Southern Rocky Mountains are a leading edge of climate change and have experienced record-breaking fires in recent years. The change in post-fire regeneration and forest resilience could potentially include future ecological trajectories. In this paper, we examined patterns of post-fire spectral recovery using Landsat time series. Additionally, we utilized random forest models to analyze the impact of climate and burn severity on three fire events in the Southern Rocky Mountains. Fifteen years following the fires, none of the burned stands …

A Pantropical Assessment Of Deforestation Caused By Industrial Mining, Stefan Giljum, Victor Maus, Nikolas Kuschnig, Sebastian Luckeneder, Michael Tost, Laura J. Sonter, Anthony J. Bebbington

Geography

Growing demand for minerals continues to drive deforestation worldwide. Tropical forests are particularly vulnerable to the environmental impacts of mining and mineral processing. Many local- to regional-scale studies document extensive, long-lasting impacts of mining on biodiversity and ecosystem services. However, the full scope of deforestation induced by industrial mining across the tropics is yet unknown. Here, we present a biome-wide assessment to show where industrial mine expansion has caused the most deforestation from 2000 to 2019. We find that 3,264 km2 of forest was directly lost due to industrial mining, with 80% occurring in only four countries: Indonesia, Brazil, Ghana, …

Emerging Hot Spot Analysis To Indicate Forest Conservation Priorities And Efficacy On Regional To Continental Scales: A Study Of Forest Change In Selva Maya 2000-2020, Nicholas Cuba, Laura A. Sauls, Anthony J. Bebbington, Denise Humphreys Bebbington, Avecita Chicchon, Pilar Delpino Marimón, Oscar Diaz, Susanna Hecht, Susan Kandel, Tracey Osborne, Rebecca Ray, Madelyn Rivera, John Rogan, Viviana Zalles

Geography

Despite the importance of preserving contiguous tropical forest areas to maintain biodiversity and terrestrial carbon stocks, methodological challenges continue to hinder broad-scale analysis of threats to these forests. Emerging Hot Spot Analysis (EHSA) is a spatial-statistical method that conveys complex information about the temporal dynamics of deforestation across a range of moderate to coarse spatial scales. Using Global Forest Change (GFC) data as inputs, EHSA produces spatially comprehensive, gridded outputs that represent a standardized, reproduceable way to instantiate contiguous forest tracts as spatial objects. Doing so allows aggregation of other GFC-derived values and analysis of alternative geographic configurations besides sub-national …

New Records Of Digenetic Trematodes Infecting Melanoides Tuberculata (O.F. Müller, 1774) In Florida, Usa, Lori R. Tolley-Jordan, Michael A. Chadwick, Jimmy K. Triplett

Research, Publications & Creative Work

Melanoides tuberculata is a well-known invasive, freshwater snail and intermediate host for many species of parasitic trematodes. Despite being well established in Florida’s freshwater systems, little work has been conducted to document the associated trematodes of the snails. Live snails were collected from 11 sites from 25 locations sampled across the state of Florida, USA of which individuals from six sites were found to be infected with trematodes. Gross morphological characters and phylogenetic analysis using 18S rRNA and ITS2 gene regions, were used to identify these trematode taxa. Snails infected with the gill flukes, Centrocestus formosanus and Haplorchis pumilio (Heterophyidae) …

Comparing Trebouxia Diversity In Lichen Genera Sympatric With The Niebla Species Complex., Anthony Perugini, Louise A. Lewis, Zachary M. Muscavitch

Undergraduate Papers

Lichens are one of the most successful mutualisms on Earth. The ecology and distribution of lichen symbionts likely influences their association and genetic structure . Two sister genera of lichenized fungi Niebla and Vermilicinia are endemic to the fog deserts on the west coast of North America. Species of Trebouxia, a genus of green algae found worldwide, are the associated photobiont partners to the Niebla/Vermilicinia species complex. Recent work demonstrated that Niebla and Vermilicinia are highly specific for only a few closely related Trebouxia molecular species (OTUs). This project examines the diversity and broad specificity of algae with lichen …

Molecular Genetic Investigation Of Twins, Families, And Populations, Jeffrey John Beck

Dissertations and Theses

Twins have long been of interest for illuminating genetic and environmental influences on human traits and diseases. These explorations have been accelerated by the substantial amount of information collected from twins and their families participating in twin registers around the world. In this dissertation, I review what is known and what remains unknown about the biology and genetics of twins and the underlying twinning process. To elucidate additional genetic factors of the twinning process, I employed pedigree-based analysis to identify genetic regions shared among distantly related mothers of dizygotic twins. The shared regions may potentially contain rare genetic variants with …

Maternal Drivers Of Reproductive Output In The Lizard Family Scincidae: A Phylogenetic Comparative Approach, William Zang

West Chester University Master’s Theses

Scincidae is one of the most diverse families of squamates, comprising over 1,300 species of lizards with a variety of life history and ecological traits. This diversity includes three reproductive modes, where some species reproduce via oviparity (egg-laying), viviparity (live birth) or use of a mixed strategy (females switch modes). In this study, it was sought whether reproductive output differs between scincid species using these reproductive modes. Reproductive output is defined as the average product of offspring abundance and size per reproductive event, representing the reproductive effort of an individual. Additionally, the importance of phylogeny (evolutionary relatedness) and a suite …

Satellite Evidence Of Canopy-Height Dependence Of Forest Drought Resistance In Southwestern China, Peipei Xu, Wei Fang, Tao Zhou, Hu Li, Xiang Zhao, Spencer Berman, Ting Zhang, Chuixiang Yi

Publications and Research

The frequency and intensity of drought events are increasing with warming climate, which has resulted in worldwide forest mortality. Previous studies have reached a general consensus on the size-dependency of forest resistance to drought, but further understanding at a local scale remains ambiguous with conflicting evidence. In this study, we assessed the impact of canopy height on forest drought resistance in the broadleaf deciduous forest of southwestern China for the 2010 extreme drought event using linear regression and a random forest (RF) model. Drought condition was quantified with standardized precipitation evapotranspiration index (SPEI) and drought resistance was measured with the …

Insects As Indicators Of Climate Change: A Literature Review, Amy Catalano

Department of Entomology: Distance Master of Science Projects

The International Panel on Climate Change (IPCC) has consistently predicted rising global temperatures since it began reporting in 1988. Researchers have noted that climate extremes have been identified beginning in the 1990s and are apparent in various climate indicators. The most recent IPCC reports show that the rate of warming has sped up considerably, and that global warming will increase from pre-industrial levels by 1.5 degrees Celsius in the next 30 years, and possibly by 2 degrees C if considerable mitigation efforts are not put in place (IPCC, 2021). By 2017 global temperatures had already increased by about 1 degree …

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 …

An Expert-Curated Global Database Of Online Newspaper Articles On Spiders And Spider Bites, Stefano Mammola, Laura Segura-Hernández, Et Al.

School of Biological Sciences: Faculty Publications

Mass media plays an important role in the construction and circulation of risk perception associated with animals. Widely feared groups such as spiders frequently end up in the spotlight of traditional and social media. We compiled an expert-curated global database on the online newspaper coverage of human-spider encounters over the past ten years (2010– 2020). This database includes information about the location of each human-spider encounter reported in the news article and a quantitative characterisation of the content—location, presence of photographs of spiders and bites, number and type of errors, consultation of experts, and a subjective assessment of sensationalism. In …

Greening The Grassroots: Rethinking African Conserva-Tion Funding, R Paul, J Chick, Emanuel Sulle, F Nelson

East Africa Institute

The purpose of this report is to document these issues around existing funding practices in the conservation field in Africa, focusing on both challenges and emerging solutions. Through collecting feedback and insights from both African civil society organizations (CSOs) and funders, the report seeks to shed light on the key barriers and challenges that both groups face and to develop recommendations for ways to improve funding practices. The report thus provides greater empirical evidence for getting more and better funding into local hands at the point of impact.

Mechanisms Of Memory Updating: State Dependency Vs. Reconsolidation, Christopher Kiley, Colleen M. Parks

Psychology Faculty Research

Reactivating a memory trace has been argued to put it in a fragile state where it must undergo a stabilization process known as reconsolidation. During this process, memories are thought to be susceptible to interference and can be updated with new information. In the spatial context paradigm, memory updating has been shown to occur when new information is presented in the same spatial context as old information, an effect attributed to a reconsolidation process. However, the integration concept holds that memory change can only occur when reactivation and test states are the same, similar to a state-dependent effect. Thus, in …

Where's The Beef? Meat Shortages, Farmer Needs, And Long-Term Recovery Policies In A Pandemic Era, Kim Vu-Dinh

Faculty Scholarship

COVID-19 not only affected every hospital bed in the nation--if not the world; it also affected nearly every dinner table in America and beyond. Supply chain disruptions caused by the pandemic highlighted deep-seated problems with how we get our meat, and how difficult we make it for American farmers to sell to the family next door. Within a few months of the first reported case in the US, hundreds of workers from just two meat-processing plants on American shores became infected with COVID-19, and imports from around the world came to a standstill as factories and shipping companies were forced …

Influence Of Land Use On Changes Of Sediment Budget Components: Western Iran Case Study, Fatemeh Sedighi, Abdulvahed Khaledi Darvishan, Valentin Golosov, Mohamad Reza Zare, Velibor Spalevic

Turkish Journal of Agriculture and Forestry

Understanding the processes of displacement and redistribution of soil particles caused by different erosion types is considered an efficient sediment management tool in various scales from the field plot to the watershed. The rainfed agriculture practices on high gradient slopes are one of the main sources of accelerated soil erosion due to the disturbance of soil structure by tillage processes. Therefore, the present study aimed to investigate the synergistic effect of rainfed agriculture practices and slope gradient on soil erosion using the activity concentrations of 137Cs fallout in Khamsan experimental watershed, western Iran. The diffusion and migration model was used …

Biochemical Content Of Cherry Laurel (Prunus Laurocerasus L.) Fruits With Edible Coatings Based On Caseinat, Semperfresh And Lecithin, Yasemi̇n Yavuz Abanoz, Zühal Okcu

Turkish Journal of Agriculture and Forestry

Cherry laurel is one of the most important cherry species and naturally grown in Black sea region in Turkey. Its fruits are sold at high price in local markets in northern parts of Turkey. Cherry laurel fruits are very perishable with a limited shelf life due to a high metabolic activity and susceptibility to mechanical damage and microbial attack. The effect of edible coatings (EC) based on caseinat, Semperfresh and lecithin on the fruit quality, bioactive content and antioxidant activity of cherry laurel fruits stored at 4 ± 1 °C for 15 days was evaluated. The EC fruits compared with …

Evaluating Population Genetic Structure And Potential Genomic Signals Of Natural Selection In A Migratory Songbird (Protonotaria Citrea), Tyler A. Hohenstein

Theses and Dissertations

In this study I attempted to further resolve the population genetic structure in the Prothonotary Warbler (Protonotaria citrea), and conducted an outlier SNP analysis and exploratory gene ontology analysis to investigate potential ongoing natural selection in the species. This analysis of population structure confirms previous work by DeSaix et al. (2019), where weak population structure was observed between eastern sites along the Atlantic Coastal Plain, and western sites in the Mississippi Alluvial Valley, possibly due to a genetic discontinuity across the Appalachian Mountains. I conducted two forms of outlier SNP analyses, a principal component analysis (PCA)-based approach to identify SNPs …

A loose collection of paragraphs by those who interacted with him addresses Carlquist's tremendous botanical output, teaching, mentorship, scientific scholarship, and his roles as a colleague and friend.

The Improvement Of The Regional Regulatory Governance System For Radiation Risk Management: Spatial Analysis On Radiation Hazards In South Korea, Sangwon Lee, Jaewon Lim, Chan Goo Yi

Public Policy and Leadership Faculty Research

Since the 2011 Fukushima nuclear power plant accident, nuclear regulators have strength-ened safety standards or decided to decommission the nuclear power plant. The vast majority of radiation is from nuclear power plants, so safety measures are also concentrated in nuclear power plants. Radioactive materials located much closer to the people are scattered around the nation. However, it is difficult for citizens to predict the radiation risk around them because regulatory agencies do not provide adequate information on radiation. The main goal of this study is to analyze the spatial distribution patterns of radioactive materials that serve as indicators for potential …

Re-Storying Grant Creek: A Case Study Of Relational Dynamics On A Degraded Montana Stream, Seamus Rucci Land

Graduate Student Theses, Dissertations, & Professional Papers

The UN Decade on Ecosystem Restoration began in 2021, and after a history of contentious ethical debates, ecological restoration is increasingly portrayed as a viable framework for combating environmental degradation and supporting more healthy and stable social-ecological systems. The proposed ecological restoration of Grant Creek, a degraded stream near Missoula, Montana, offers an opportunity to connect a restoration site to the broader, rapidly growing field of restoration practice. It also allows the opportunity to forward the ‘relational turn’ proposed by many in the sustainability sciences as an ontological and methodological means to move beyond positivist portrayals of social-ecological systems, which …

Regenerative Agriculture Effects On Invertebrate And Bird Communities And Insect-Provided Ecosystem Services, Alex Michels

Electronic Theses and Dissertations

Conventional agricultural practices can have unintended consequences on the environment and wildlife. Insects and birds are declining at rapid rates around the world, and the current conventional agricultural paradigm is a major driver through habitat loss and the intensification of production. Invertebrates in agroecosystems provide services to both farmers and the rest of society. Regenerative systems may promote the functioning of an agroecosystem by influencing invertebrate abundance, diversity, and ecosystem services and mitigate bird and insect declines through conservation practices that increase soil health, reduce disturbances, and increase biological diversity. Here I address knowledge gaps of the effects of regenerative …

Fruits Of Our Labor: Exploring The Impacts Of A Nonprofit Seed Bank On Indigenous Communities In The Southwestern United States, Rachel Mary Davis

Graduate Research Theses & Dissertations

This thesis explores the ways that the nonprofit Native Seeds/SEARCH, of Tucson, Arizona interfaces with Indigenous communities and the local seed and food systems in the Southwest United States. The thesis argues that Native seed and food sovereignty have different meanings for different Indigenous people, and that nonprofits working with Indigenous communities need to consider input from them when deciding how to catalogue, regenerate and sustain healthy grow outs for the future, especially in the light of climate change and drought.

Growing Meat On Plants: Using Intermediate Cbd-Rgd Fusion Proteins To Improve Bovine Satellite Cell Attachment On Cellulose-Based Scaffolds, Julian Cohen

Pitzer Senior Theses

Cellular agriculture is an emerging technology aiming to replace existing methods for animal agriculture with tissue engineering and cell culture-based technologies. Cultured meat falls within this purview, using a biomimetic approach to recreate animal muscle tissue through tissue engineering. In the attempt to diminish the necessity of animal-derived materials within this process, plant-based scaffolds can be used as a substrate upon which stem cells are cultured. Due to the unfavorable environment of cellulose for mammalian cell-surface proteins, the approach was taken of coating cellulose nanofiber films with a fusion protein composed of a cellulose binding domain (CBD) protein and the …

Patterning Ecological Restoration After Weeds, Stephen L. Young, Erik P. Hamerlynck

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The United Nations Decade on Ecosystem Restoration aims to prevent, halt, and reverse the degradation of ecosystems on every continent. Disturbances stemming from anthropogenic or natural causes make plant community restoration challenging. The introduction of fast-growing weeds that generate high biomass and produce copious seed is most threatening to plant communities. A paradigm shift in ecosystem restoration is needed that emphasizes traits and affected ecological processes similar to weeds. The repeated introduction of seed from native plants with weedy characteristics follows the propagule pressure and evolution of invasiveness hypotheses. In targeting areas with heavy weed populations, native plants could establish …

Corn Nitrogen Nutrition Index Prediction Improved By Integrating Genetic, Environmental, And Management Factors With Active Canopy Sensing Using Machine Learning, Dan Li, Yuxin Miao, Curtis J. Ransom, Gregory Mac Bean, Newell R. Kitchen, Fabián G. Fernández, John E. Sawyer, James J. Camberato, Paul R. Carter, Richard B. Ferguson, David W. Franzen, Carrie A.M. Laboski, Emerson D. Nafziger, John F. Shanahan

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Accurate nitrogen (N) diagnosis early in the growing season across diverse soil, weather, and management conditions is challenging. Strategies using multi-source data are hypothesized to perform significantly better than approaches using crop sensing information alone. The objective of this study was to evaluate, across diverse environments, the potential for integrating genetic (e.g., comparative relative maturity and growing degree units to key developmental growth stages), environmental (e.g., soil and weather), and management (e.g., seeding rate, irrigation, previous crop, and preplant N rate) information with active canopy sensor data for improved corn N nutrition index (NNI) prediction using machine learning methods. Thirteen …

A Stillness In The Desert? Engaging The Public Through An Immersive Exploration Of Southwest Soundscapes, Julian Kilker, Thomas Bjelic

Creative Collaborations

The pandemic highlighted the anthropocentric nature of soundscapes, while the recent popularity of electric cars, quadcopters, and “noise cancellation” earbuds demonstrated how consumer products can rapidly change our awareness of sound. While light pollution is already extensively addressed in scholarly research, popular works such as The End of Night, and public engagement such as The International Dark Sky Association, the complex interplay of sound, natural resources, and public engagement is still emerging, particularly in creative fields.

Two UNLV scholars and artists are collaborating on this project: Julian Kilker, who specializes in visual and emerging technology research, and Tom Bjelic, who …
