Wildland Resources Faculty Publications

Delineation, protection, and restoration of habitats provide the basis for endangered and threatened species recovery plans. Species recovery plans typically contain guidelines that provide managers with a scientific basis to designate and manage critical habitats. As such, habitat guidelines are best developed using data that capture the full diversity of ecological and environmental conditions that provide habitat across the species’ range. However, when baseline information, which fails to capture habitat diversity, is used to develop guidelines, inconsistencies and problems arise when applying those guidelines to habitats within an ecologically diverse landscape. Greater sage‐grouse (Centrocercus urophasianus; sage‐ grouse) populations …

Spatial And Temporal Trends Of Southeastern Florida's Octocoral Comunity, Alexandra Hiley Dec 2019

Spatial And Temporal Trends Of Southeastern Florida's Octocoral Comunity, Alexandra Hiley

HCNSO Student Theses and Dissertations

In the Caribbean, local and global stressors have driven significant declines in scleractinian coral cover up to 80% in only three decades. Following these declines, phase shifts in benthic community composition have been reported. Shifts towards macroalgal dominance has been the most widely observed case, however, shifts towards octocoral and sponge dominance have also been reported. In Florida, USA, the Florida Reef Tract is an extensive barrier reef system that contains diverse assemblages of corals, sponges, fish, and other taxa. The Southeast Florida Reef Tract (SEFRT) within the Southeast Florida Coral Reef Conservation Area is the northern portion of this …

Articles, Abstracts, and Reports

The Human Proteome Organization's (HUPO) Human Proteome Project (HPP) developed Mass Spectrometry (MS) Data Interpretation Guidelines that have been applied since 2016. These guidelines have helped ensure that the emerging draft of the complete human proteome is highly accurate and with low numbers of false-positive protein identifications. Here, we describe an update to these guidelines based on consensus-reaching discussions with the wider HPP community over the past year. The revised 3.0 guidelines address several major and minor identified gaps. We have added guidelines for emerging data independent acquisition (DIA) MS workflows and for use of the new Universal Spectrum Identifier …

Arctic Thaw: Environmental Exploitation For Economic Profit, Stephen F. Moulton Dec 2019

Arctic Thaw: Environmental Exploitation For Economic Profit, Stephen F. Moulton

HCNSO Student Capstones

“Arctic Thaw: Environmental Exploitation for Economic Profit,” is a comprehensive, interdisciplinary assessment of Arctic climate change (CC) impacts. Arctic CC alters the regions’ temperature, annual ice cover, and sea levels. This alteration influences the global economy through enriched international trade and fossil hydrocarbon extraction developments. This capstone examines the Arctic’s response to CC through economic statistical analysis, tracking relative sea-level (RSL) trends, as well as performing hydrographic and modeling reviews. The Northern Rim Countries (NRCs) economic analysis assesses potential CC and GSLR impacts by applying statistical techniques to calculate its effect on each country’s gross domestic product (GDP). The tidal …

Strange, Taran Grant, Edmund D. Brodie Jr., Edmund D. Brodie Jr. Dec 2019

Variations In Tetrodotoxin Levels In Populations Of Taricha Granulosa Are Expressed In The Morphology Of Their Cutaneous Glands, Pedro Luiz Mailho-Fontana, Carlos Jared, Marta Maria Antoniazzi, Juliana Mozer Sciani, Daniel Carvalho Pimenta, James P. Strange, Taran Grant, Edmund D. Brodie Jr., Edmund D. Brodie Jr.

Biology Faculty Publications

Tetrodotoxin (TTX), one of the most toxic substances in nature, is present in bacteria, invertebrates, fishes, and amphibians. Marine organisms seem to bioaccumulate TTX from their food or acquire it from symbiotic bacteria, but its origin in amphibians is unclear. Taricha granulosa can exhibit high TTX levels, presumably concentrated in skin poison glands, acting as an agent of selection upon predatory garter snakes (Thamnophis). This co-evolutionary arms race induces variation in T. granulosa TTX levels, from very high to undetectable. Using morphology and biochemistry, we investigated differences in toxin localization and quality between two populations at the extremes …

Biologic And Hydrologic Controls Of Water Quality In Urbanizing Semi-Arid Watersheds, Erin Fleming Jones Dec 2019

Biologic And Hydrologic Controls Of Water Quality In Urbanizing Semi-Arid Watersheds, Erin Fleming Jones

Theses and Dissertations

This dissertation analyzed the effect of biologic and hydrologic processes on water quality in urban, semi-arid watersheds. In the first chapter, we analyzed bacterioplankton and water quality along elevation and urbanization gradients in three Wasatch Mountain watersheds across three seasons. We found that trace metals correlated with bacterioplankton composition and that the typical dispersal of bacteria from headwater sources (soil or groundwater) along the longitudinal pathway was drastically disrupted by the presence of large reservoirs. In the second chapter, we used high-frequency sensor data collected in streams above and below the urban center in the three watersheds to estimate the …

Watching Grass Grow: How Soil Moisture Affects Vesicular-Arbuscular Mycorrhizae And Growth In Little Bluestem, Laura M. Jones Dec 2019

Watching Grass Grow: How Soil Moisture Affects Vesicular-Arbuscular Mycorrhizae And Growth In Little Bluestem, Laura M. Jones

Honors Scholar Theses

Vesicular-arbuscular mycorrhizae (VAM) are an ancient mutualism in which soil-dwelling fungi enhance plant absorption of phosphorus and nitrogen in exchange for photosynthates. VAM are sensitive to changes in soil moisture and nutrient content, fluctuating between mutualism and parasitism depending on conditions of drought stress and nutrient deficiency. Understanding how VAM respond to precipitation changes is crucial for both conservation and agricultural purposes. To test how soil moisture changes the effects of VAM colonization and growth in little bluestem (Schizachyrium scoparium), a common prairie grass, I planted 300 seeds in a greenhouse in sterilized soil and soil inoculated with …

Walker, Dahlia N. Amato, Douglas V. Amato, Olga V. Mavrodi, Derek L. Patton, Dmitri V. Mavrodi

Faculty Publications

Plant-derived aldehydes are constituents of essential oils that possess broad-spectrum antimicrobial activity and kill microorganisms without promoting resistance. In our previous study, we incorporated p-anisaldehyde from star anise into a polymer network called PANDAs (Pro-Antimicrobial Networks via Degradable Acetals) and used it as a novel drug delivery platform. PANDAs released p-anisaldehyde upon a change in pH and humidity, and controlled growth of the multi-drug resistant pathogen Pseudomonas aeruginosa PAO1. In this study, we identified cellular pathways targeted by p-anisaldehyde, by generating 10,000 transposon mutants of PAO1 and screened them for hypersensitivity to p-anisaldehyde. To improve the …

A Male-Female Genotype-By-Genotype Interaction Mediates The Effect Of Mating On Female Immunity In Decorated Crickets, Kylie J. Hampton Dec 2019

A Male-Female Genotype-By-Genotype Interaction Mediates The Effect Of Mating On Female Immunity In Decorated Crickets, Kylie J. Hampton

Theses and Dissertations

Sexually antagonistic coevolution should lead to the rapid divergence of male and female genotypes related to the effects of ejaculatory substances on female physiology. Hence, the outcome of mating should depend on an interaction between male and female genotypes. Although mating has been shown to influence female immune responses in diverse insect taxa, a male-female genotype-by-genotype effect on female immunity post-mating remains largely unexplored. Here, we investigate both the effects of mating on female immunity and the potential for a male-by-female genotype interaction on the form and magnitude of this response in decorated crickets. Females from three distinct genotypic backgrounds …

Structural Basis Of Non-Canonical Transcriptional Regulation By The A-Bound Iron-Sulfur Protein Whib1 In M. Tuberculosis, Tao Wan, Shanren Li, Daisy Guiza Beltran, Andrew Schacht, Lu Zhang, Donald F. Becker, Limei Zhang

Department of Biochemistry: Faculty Publications

WhiB1 is amonomeric iron–sulfur cluster-containing transcription factor in the WhiB-like family that is widely distributed in actinobacteria including the notoriously persistent pathogen Mycobacterium tuberculosis (M. tuberculosis). WhiB1 plays multiple roles in regulating cell growth and responding to nitric oxide stress inM. tuberculosis, but its underlying mechanism is unclear. Here we report a 1.85 A° -resolution crystal structure of the [4Fe–4S] cluster-bound (holo- )WhiB1 in complex with the C-terminal domain of the 70-family primary sigma factor A of M. tuberculosis containing the conserved region 4 (A 4). Region 4 of the 70-family primary sigma factors is commonly used by transcription factors …

Reconstructing Energy Flow Through Modern And Historical Marine Communities: Insights From Amino Acid Isotope Analysis, Emma A. Elliott Smith Dec 2019

Reconstructing Energy Flow Through Modern And Historical Marine Communities: Insights From Amino Acid Isotope Analysis, Emma A. Elliott Smith

Biology ETDs

The fundamental currency of life is energy. Organisms need energy to grow, to survive and to reproduce. Understanding the acquisition of energy by consumers is thus a foundational aspect of biological research. This is especially important in the modern era, as impacts of ongoing anthropogenic effects will be mediated or amplified through food webs. Here, I explore how isotopic analysis of individual amino acids – a technique new to ecological studies – can be used to trace energy flow through animal communities in modern and ancient time periods. In particular, I focus on kelp forest food webs, which are nearshore …

Behavioural Risks In Female Dogs With Minimal Lifetime Exposure To Gonadal Hormones, Melissa J. Starling, Anne Fawcett, Bethany Wilson, James Serpell, Paul Mcgreevy Dec 2019

Behavioural Risks In Female Dogs With Minimal Lifetime Exposure To Gonadal Hormones, Melissa J. Starling, Anne Fawcett, Bethany Wilson, James Serpell, Paul Mcgreevy

Physiology Collection

Spaying of female dogs is a widespread practice, performed primarily for population control. While the consequences of early spaying for health are still being debated, the consequences for behaviour are believed to be negligible. The current study focused on the reported behaviour of 8981 female dogs spayed before 520 weeks (ten years) of life for reasons other than behavioural management, and calculated their percentage lifetime exposure to gonadal hormones (PLGH) as a proportion of their age at the time of being reported to the online Canine Behavioral Assessment and Research Questionnaire (C-BARQ). We found that 23 behaviours differed between entire …

Improving Lake Mixing Process Simulations In The Community Land Model By Using K Profile Parameterization, Qunhui Zhang, Jiming Jin, Xiaochun Wang, Phaedra E. Budy, Nick Barrett, Sarah E. Null Dec 2019

Improving Lake Mixing Process Simulations In The Community Land Model By Using K Profile Parameterization, Qunhui Zhang, Jiming Jin, Xiaochun Wang, Phaedra E. Budy, Nick Barrett, Sarah E. Null

Watershed Sciences Faculty Publications

We improved lake mixing process simulations by applying a vertical mixing scheme, K profile parameterization (KPP), in the Community Land Model (CLM) version 4.5, developed by the National Center for Atmospheric Research. Vertical mixing of the lake water column can significantly affect heat transfer and vertical temperature profiles. However, the current vertical mixing scheme in CLM requires an arbitrarily enlarged eddy diffusivity to enhance water mixing. The coupled CLM-KPP considers a boundary layer for eddy development, and in the lake interior water mixing is associated with internal wave activity and shear instability. We chose a lake in Arctic Alaska and …

Pharmacological Or Genetic Targeting Of Transient Receptor Potential (Trp) Channels Can Disrupt The Planarian Escape Response, Ziad Sabry , '21, A. Ho, Danielle Ireland, Christina Rabeler, O. Cochet-Escartin, Eva-Maria S. Collins Dec 2019

Pharmacological Or Genetic Targeting Of Transient Receptor Potential (Trp) Channels Can Disrupt The Planarian Escape Response, Ziad Sabry , '21, A. Ho, Danielle Ireland, Christina Rabeler, O. Cochet-Escartin, Eva-Maria S. Collins

Biology Faculty Works

In response to noxious stimuli, planarians cease their typical ciliary gliding and exhibit an oscillatory type of locomotion called scrunching. We have previously characterized the biomechanics of scrunching and shown that it is induced by specific stimuli, such as amputation, noxious heat, and extreme pH. Because these specific inducers are known to activate Transient Receptor Potential (TRP) channels in other systems, we hypothesized that TRP channels control scrunching. We found that chemicals known to activate TRPA1 (allyl isothiocyanate (AITC) and hydrogen peroxide) and TRPV (capsaicin and anandamide) in other systems induce scrunching in the planarian species Dugesia japonica and, except …

Invasive Phragmites Australis Management Outcomes And Native Plant Recovery Are Context Dependent, Christine B. Rohal, Chad R. Cranney, Eric L. G. Hazelton, Karin M. Kettenring Dec 2019

Invasive Phragmites Australis Management Outcomes And Native Plant Recovery Are Context Dependent, Christine B. Rohal, Chad R. Cranney, Eric L. G. Hazelton, Karin M. Kettenring

Ecology Center Publications

The outcomes of invasive plant removal efforts are influenced by management decisions, but are also contingent on the uncontrolled spatial and temporal context of management areas. Phragmites australis is an aggressive invader that is intensively managed in wetlands across North America. Treatment options have been understudied, and the ecological contingencies of management outcomes are poorly understood. We implemented a 5‐year, multi‐site experiment to evaluate six Phragmites management treatments that varied timing (summer or fall) and types of herbicide (glyphosate or imazapyr) along with mowing, plus a nonherbicide solarization treatment. We evaluated treatments for their influence on Phragmites and native plant …

Faculty Research 2019

Urinary tract infection (UTI) is a common complication in patients with urolithiasis. This study aimed to compare clinical manifestations and treatment outcomes among UTI patients with or without urolithiasis. It also focused on identifying relationships among urolithiasis, uroseptic shock, and acute kidney injury (AKI). This retrospective study enrolled hospitalized UTI patients who underwent imaging in an acute care setting from January 2006 to March 2015. Of 662 participants enrolled, 113 (17.1%) had urolithiasis, 107 (16.2%) developed uroseptic shock, and 184 (27.8%) developed AKI. A multivariate logistic regression analysis showed that in UTI patients, urolithiasis is associated with an increased risk …

Tunnel-Tube And Fourier Methods For Measuring Three-Dimensional Medium Reaction Force In Burrowing Animals, Alexis Moore Crisp, Clinton J. Barnes, David V. Lee Dec 2019

Tunnel-Tube And Fourier Methods For Measuring Three-Dimensional Medium Reaction Force In Burrowing Animals, Alexis Moore Crisp, Clinton J. Barnes, David V. Lee

Life Sciences Faculty Research

Subterranean digging behaviors provide opportunities for protection, access to prey, and predator avoidance for a diverse array of vertebrates, yet studies of the biomechanics of burrowing have been limited by the technical challenges of measuring kinetics and kinematics of animals moving within a medium. We describe a new system for measuring 3D reaction forces during burrowing, called a ‘tunnel-tube’, which is composed of two, separately instrumented plastic tubes: an ‘entry tube’ with no medium, in series with a ‘digging tube’ filled with medium. Mean reaction forces are measured for a digging bout and Fourier analysis is used to quantify the …

A Multivariate Ecological Approach To Delineate Unionid Freshwater Mussel Species, Ava M. Laszlo Dec 2019

A Multivariate Ecological Approach To Delineate Unionid Freshwater Mussel Species, Ava M. Laszlo

Biology Theses

Freshwater mussels represent one of the most imperiled faunal groups on the planet and are critical to freshwater ecosystems. If mussel species are not carefully defined, our conservation plans may miss differences in the habitat needs of different species and the conservation strategies may not be as successful. Because ecological niche models can be used to provide evidence to support similar or dissimilar ecological niches and habitat requirements, I used modelling to forecast suitable habitat for Fusconaia askewi and F. lananensis, two purported threatened Texas species. The modeling results indicated that these species are not ecologically different. Based upon …

Configuration And Location Of Small Urban Gardens Affect Colonization By Monarch Butterflies, Adam M. Baker, Daniel A. Potter Dec 2019

Configuration And Location Of Small Urban Gardens Affect Colonization By Monarch Butterflies, Adam M. Baker, Daniel A. Potter

Entomology Faculty Publications

Ecological theory predicts that specialist insect herbivores are more likely to locate and colonize host plants growing in relatively sparse or pure stands compared to host plants growing amongst diverse non-host vegetation. We tested the hypothesis that increasing the apparency and accessibility of milkweed (Asclepias spp.) host plants in small polyculture gardens would boost their colonization by the monarch butterfly (Danaus plexippus), an iconic native species of conservation concern. We established replicated gardens containing the identical mix of milkweeds, flowering nectar sources, and non-host ornamental grasses but arranged in three different spatial configurations that were monitored for …

Argulus From The Pascagoula River, Ms, Usa, With An Emphasis On Those Of The Threatened Gulf Sturgeon, Acipenser Oxyinchus Desotoi, Michael J. Andres, Jeremy M. Higgs, Paul O. Grammer, Mark S. Peterson Dec 2019

Argulus From The Pascagoula River, Ms, Usa, With An Emphasis On Those Of The Threatened Gulf Sturgeon, Acipenser Oxyinchus Desotoi, Michael J. Andres, Jeremy M. Higgs, Paul O. Grammer, Mark S. Peterson

Faculty Publications

Species of Argulus (Branchiura Thorell, 1864) are common ectoparasites of freshwater, estuarine, and marine fishes. Argulid identification and taxonomy is often confusing because many species are reported to parasitize multiple host species, have similar morphological characters, and come from various salinity regimes. Gulf sturgeon is an anadromous fish natal to drainages in the north-central Gulf of Mexico, and as with many endangered species, has a poorly documented parasite community. During Gulf sturgeon tagging and monitoring studies (2016–2019) in the Pascagoula River, MS, USA, species of Argulus were collected from Gulf sturgeon as well as other incidentally captured fishes. Argulus flavescens …

The Role Of Growth Arrest Specific 6 And Axl Signaling In Skeletal Muscle Regeneration, Marc Shigeru Matsumura Dec 2019

The Role Of Growth Arrest Specific 6 And Axl Signaling In Skeletal Muscle Regeneration, Marc Shigeru Matsumura

Theses and Dissertations

Skeletal muscle regeneration is a critical process that replaces damaged muscle fibers with new fibers. The regenerative process can be segmented into four main phases: necrosis, inflammation, regeneration, and maturation. While many of the key signaling molecules are known and characterized, there are still gaps in our understanding of how this process is regulated. While it is reported that growth arrest specific 6 (Gas6) and its receptor Axl are expressed in mature muscle tissue, nothing is known about the effect that Gas6 and Axl have on regulating skeletal muscle regeneration. In this study we investigated the regenerative process in a …

Local‐Regional Similarity In Drylands Increases During Multiyear Wet And Dry Periods And In Response To Extreme Events, Matthew D. Petrie, D. P.C. Peters, N. D. Bruss, W. Ji, H. M. Savoy Dec 2019

Local‐Regional Similarity In Drylands Increases During Multiyear Wet And Dry Periods And In Response To Extreme Events, Matthew D. Petrie, D. P.C. Peters, N. D. Bruss, W. Ji, H. M. Savoy

Life Sciences Faculty Research

Climate change is predicted to impact ecosystems through altered precipitation (PPT) regimes. In the Chihuahuan Desert, multiyear wet and dry periods and extreme PPT pulses are the most influential climatic events for vegetation. Vegetation responses are most frequently studied locally, and regional responses are often unclear. We present an approach to quantify correlation of PPT and vegetation responses (as Normalized Difference Vegetation Index [NDVI]) at the Jornada ARS‐LTER site (JRN; 550 km2 area) and the surrounding dryland region (from 0 to 500 km distance; 400,000 km2 study area) as a way to understand regional similarity to locally observed patterns.

Plant Hormones Differentially Control The Sub-Cellular Localization Of Plasma Membrane Microdomains During The Early Stage Of Soybean Nodulation, Zhenzhen Qiao, Prince Zogli, Marc Libault Dec 2019

Plant Hormones Differentially Control The Sub-Cellular Localization Of Plasma Membrane Microdomains During The Early Stage Of Soybean Nodulation, Zhenzhen Qiao, Prince Zogli, Marc Libault

Department of Agronomy and Horticulture: Faculty Publications

Phytohormones regulate the mutualistic symbiotic interaction between legumes and rhizobia, nitrogen-fixing soil bacteria, notably by controlling the formation of the infection thread in the root hair (RH). At the cellular level, the formation of the infection thread is promoted by the translocation of plasma membrane microdomains at the tip of the RH. We hypothesize that phytohormones regulate the translocation of plasma membrane microdomains to regulate infection thread formation. Accordingly, we treated with hormone and hormone inhibitors transgenic soybean roots expressing fusions between the Green Fluorescent Protein (GFP) and GmFWL1 or GmFLOT2/4, two microdomain-associated proteins translocated at the tip of the …

Introduction
Across the African Diaspora, hair is synonymous with identity. As such, Black women use a variety of hair products, which often contain more endocrine-disrupting chemicals than products used by women of other races. An emerging body of research is linking chemicals in hair products to breast cancer, but there is no validated instrument that measures constructs related to hair, identity, and breast health. The objective of this study was to develop and validate the Black Identity, Hair Product Use, and Breast Cancer Scale (BHBS) in a diverse sample of Black women to measure the social and cultural constructs associated …
