Use Of Multiple Stream Temperature Logger Models Can Alter Conclusions, Robin M. Rotman, Joanna B. Whittier, Jacob T. Westhoff, Craig P. Paukert

Faculty Publications

Remote temperature loggers are often used to measure water temperatures for ecological studies and by regulatory agencies to determine whether water quality standards are being maintained. Equipment specifications are often given a cursory review in the methods; however, the effect of temperature logger model is rarely addressed in the discussion. In a laboratory environment, we compared measurements from three models of temperature loggers at 5 to 40 °C to better understand the utility of these devices. Mean water temperatures recorded by logger models differed statistically even for those with similar accuracy specifications, but were still within manufacturer accuracy specifications. Maximum …

An Introduction To The Squirrel-Net Teaching Modules, Laurie Dizney, Patrice K. Connors, Johanna Varner, Jennifer M. Duggan, Hayley C. Lanier, Liesl P. Erb, Elizabeth A. Flaherty, Christopher J. Yahnke, John D. Hanson

AES Faculty Publications and Presentations

Although course-based undergraduate research experiences (CUREs) are gaining popularity in biology, most are designed for benchwork-based laboratory courses while few focus on field-based skills. Many barriers to implementing field CUREs exist, including the difficulty in designing authentic research that can be accomplished in a limited lab timeframe, permitting and liability issues, and problems gathering sufficient data to meaningfully analyze. Squirrel-Net (http://squirrel-net.org) is a consortium of mammalogists from eight different institutions who have worked to overcome these limitations through four field-based CUREs focused on sciurid rodents (e.g., squirrels, chipmunks, marmots, prairie dogs). Each module is linked to a national dataset, allowing …

Post Chemotherapeutic Treatment Impact On Pediatric Patients With Acute Lymphoblastic Leukemia, Roaa Alfarshooti

Wayne State University Theses

Acute lymphoblastic leukemia (ALL) is the most prevalent type of leukemia among children. It is characterized by chromosomal and genetic variations and abnormalities occurring in the leukemic cells. Prognosis predictors of ALL depend on risk-based stratification and the reaction to the initial therapy. Current treatment regimens of ALL contribute to the survival of approximately 80% of pediatric ALL patients with 90% 5-year event-free survival. Based on the patient’s features impacting prognosis and risk of therapy failure, cases can be designated to receive the adequate type of treatment regimens. The higher the risk, the more aggressive, intensive, and toxic is the …

Beyond Never-Never Land: Integrating Lidar And Geophysical Surveys At The Johnston Site, Pinson Mounds State Archaeological Park, Tennessee, Usa, Henry R. Edward, Alice P. Wright, Sarah C. Sherwood, Barrier R. Casey, Stephen B. Carmody, Christopher Van De Ven

Anthropology Faculty Research and Scholarship

Archaeologists often use near-surface geophysics or LiDAR-derived topographic imagery in their research. However, rarely are the two integrated in a way that offers a robust understanding of the complex historical palimpsests embedded within a social landscape. In this paper we present an integrated aerial and terrestrial remote sensing program at the Johnston Site, part of the larger Pinson Mounds landscape in the American MidSouth. Our work at Johnston was focused on better understanding the history of human landscape use and change so that we can begin to compare the Johnston Site with other large Middle Woodland (200 BC-AD 500) ceremonial …

Geospatial Analysis Of Flooding In The Cypress Creek Watershed Due To Urban Sprawl, Michael Roland Boucher

Walden Dissertations and Doctoral Studies

Harris County, Texas, experiences flooding almost every year, and the situation is getting worse. Uncontrolled development is leading to an increase in flooding events. This study investigated how rapid urbanization and sprawl led to a higher frequency and intensity of flooding in the Cypress Creek watershed in northern Harris County. According to urban ecology, the basis of the theoretical framework, the human actions on the environment are not just bystanders, but direct contributors as inputs. In this case, the outputs are the intensity of the flooding events caused by Hurricane Ike, the Memorial Day flood of 2016, and Hurricane Harvey. …

A Comparative Spatial And Climate Analysis Of Human Granulocytic Anaplasmosis And Human Babesiosis In New York State (2013-2018), Collin J. O'Connor

Legacy Theses & Dissertations (2009 - 2024)

Human granulocytic anaplasmosis (HGA) and human babesiosis are tick-borne diseases spread by Ixodes scapularis (the blacklegged or deer tick) and are the result of infection with Anaplasma phagocytophilum and Babesia microti, respectively. In New York State (NYS), incidence rates of these diseases increased concordantly until around 2013, when rates of HGA began to increase more rapidly than human babesiosis, and the spatial extent of the diseases diverged. Surveillance data of tick-borne pathogens (2007 to 2018) and reported human cases of HGA (n=4,297) and human babesiosis (n=2,986) (2013 to 2018) from the New York State Department of Health (NYSDOH) showed a …

Turkish Journal of Botany

Aquatic macrophytes are one of the key components of freshwater ecosystems and contribute to ecosystem functioning and environmental sustainability. They are assumed to be an ideal biomonitoring tool in long-term monitoring programs implemented by the EU Water Framework Directive due to their sensitivity to environmental factors. Therefore, this study focuses on the evaluation of the ecological status in Lake Sapanca using macrophyte composition and abundance in order to make future predictions on the health of aquatic ecosystems and to form effective management. Submerged macrophyte assemblages related to environmental parameters were investigated from February to November of 2017. A total of …

Acute Physiological Response By The Plethodontid Salamander Eurycea Cirrigera (Southern Two-Lined Salamander) To Predation Stress From Alarm Chemicals And Predator Kairomones, G A. Marvin

Biology

Plethodontid salamanders may reduce predation risk via behavioral responses to predator kairomones and alarm chemicals from injured salamanders. However, it not known whether such predator cues prompt acute physiological responses, which may enhance arousal and the physical ability to escape from a predator. I examined whether predator chemical cues elicit an acute cardiac response in Eurycea cirrigera (Green, 1831) (Southern Two-lined Salamander). I compared heart rates before and after exposure to the odor of the large predatory Pseudotriton ruber (Sonnini de Manoncourt and Latreille, 1801) (Red Salamander) and exposure to alarm chemicals from homogenized skin of conspecifics. For two controls, …

Transboundary Fisheries, Climate Change, And The Ecosystem Approach: Taking Stock Of The International Law And Policy Seascape, Cecilia Engler

Articles, Book Chapters, & Popular Press

The ecosystem approach to fisheries management is a conceptual and practical framework consistent with, and supportive of, climate change adaptation at the national and regional level. Implementing an ecosystem approach can contribute to climate change adaptation by improving ecosystem resilience and reducing vulnerability to climate change, by providing planning strategies and tools to monitor and assess the impacts of climate change on fisheries, and by relying on precautionary, flexible, and adaptive approaches that account for the uncertainties, surprises, unpredictability, and dynamism of ecosystems in a changing climate.

In this article, I provide an overview of some key considerations framing the …

Deciphering The Past To Inform The Future: Preparing For The Next (“Really Big”) Extreme Event, Debra Pc Peters, N Dylan Burruss, Gregory S. Okin, Jerry L. Hatfield, Stacey Lp Scroggs, Haitao Huang, Colby W. Brungard, Jin Yao

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

Climate change will bring more extremes in temperature and precipitation that will impact productivity and ecosystem resilience throughout agroecosystems worldwide. Historical events can be used to identify drivers that impact future events. A catastrophic drought in the US in the 1930s resulted in an abrupt boundary between areas severely impacted by the Dust Bowl and areas that were less severely affected. Historical primary production data confirmed the location of this boundary at the border between two states (Nebraska and Iowa). Local drivers of weather and soils explained production responses across the boundary before and after the drought (1926–1948). During the …

Gulf and Caribbean Research

Current abundance estimates for populations of common bottlenose dolphins (Tursiops truncatus, Montagu, 1821) in bays, sounds, and estuaries are lacking throughout most of the northwestern Gulf of Mexico, including areas of Texas and western Louisiana. To address this issue, we conducted 92 small-boat photographic identification surveys covering ~2000 km² and comprising ~11,000 km of track-line in winter and summer seasons in West Bay, TX (2014 – 2015, n = 25), the Galveston Bay, TX system (2016, n = 50), Sabine Lake, TX (2017, n = 17), and adjacent coastal waters. Individual dolphin encounter histories were constrained by …

Correlates Of Bird Collisions With Buildings Across Three North American Countries, Jared A. Elmore, Stephen B. Hager, Bradley J. Cosentino, Nastasha Hagemeyer, Eric Walters, Scott R. Loss, Et Al.

Biological Sciences Faculty Publications

Collisions with buildings cause up to 1 billion bird fatalities annually in North America. Bird-building collisions have recently received increased conservation, research, and policy attention. However, efforts to reduce collisions would benefit from studies conducted at large spatial scales across multiple study sites, with standardized methods, and with consideration of species- and life history-related variation and correlates of collisions. We addressed these research needs with a coordinated data collection effort at 40 sites across North America. We estimated collision vulnerability for 40 bird species by accounting for their North American population abundance, distribution overlap with study sites, and sampling effort. …

Food Web Effects Of Lake Trout (Salvelinus Namaycush) Invasion In Northwestern Montana, Charles Wainright

Graduate Student Theses, Dissertations, & Professional Papers

Around the turn of the 20th century, lake trout (Salvelinus namaycush) were widely introduced in several lakes and reservoirs outside their native range in western North America. Since then, lake trout have become problematic in many lakes where they were introduced, causing significant declines in popular sport fishes and native species, most notably federally protected bull trout (Salvelinus confluentus). Despite evidence that invasive fish can cause cascading trophic effects in aquatic communities, the impacts of lake trout introduction / invasion on aquatic food webs remain poorly understood. Moreover, native fish restoration programs tend to focus on suppression …

Rural Disparities In Lung Cancer Mortality: An Ecologic Study In Florida, Batel Amouyal

Honors Undergraduate Theses

Lung cancer is the leading cause of cancer death in the United States and worldwide. The higher mortality among patients with lung cancer is related to cases being diagnosed in late stage where treatment is limited. Urban and rural health outcomes are potentially influenced by differences in accessibility to health care services. We are unaware of existing research examining geographic differences in or factors related to lung cancer mortality in Florida. Therefore, this study aims to examine lung cancer mortality differences between urban and rural counties in Florida. We examined all 67 counties in Florida to investigate if a rural …

Temperature Effects On Moose (Alces Alces) Activity Patterns In Isle Royale National Park, Isabella C. Evavold

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Moose (Alces alces) in Isle Royale National Park impact the ecosystem by browsing tree species and serving as the primary food source for wolves. As a heat-sensitive species, moose are susceptible to the impacts of climate change in the southern extent of their range which includes Isle Royale. Understanding how temperature impacts moose behavior is valuable and can be used to predict how moose may respond to changing temperature in the future. GPS enabled radio-collars with three-axis accelerometers were used to collect one year of temperature and activity data from 6 cow moose in Isle Royale National Park. …

An Ecological Approach To Understanding Lethal Violence In The Us Using Stream Analogy, Jacqueline Seals

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

ABSTRACT OF CAPSTONE

Background: Lethal violence, homicides and suicides, is a growing issue in the US. Historically homicides and suicides have been studied separately, but with stream analogy of lethal violence homicides and suicides are both currents of lethal violence, just branching in opposite directions. The purpose of this study is to understand which county-level factors increase risk of lethal violence.

Methods: This ecological study combined open-source datasets to create one dataset of socioeconomic risk factors of lethal violence. Counties with 10 or more lethal violent deaths were included (n=2751). Negative Binomial models examined the relationship between risk factors and …

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 …

Long-Term Effects Of Crop-Tree Release On The Growth And Quality Of Upland White Oak Stands, Philip Jay Vogel

Theses and Dissertations--Forestry and Natural Resources

The alteration of historical disturbance regimes, forest parcelization, and varying goals among landowners all present challenges to oak management in the eastern U.S. Foresters and landowners need tools to promote oak sustainability that are applicable on small forestland holdings and within complex management plans. From this perspective, this research evaluates a crop-tree release study installed in southeastern Kentucky in 1983. The experiment includes four, 2-acre replications of three treatment levels: 20 crop-trees per acre, 34 crop-trees per acre, and a control treatment in which crop-trees were selected but not released. Half-acre measurement plots were installed at the outset of the …

Assessing The Climate Water Balance Model’S Ability To Predict Soil Moisture Variability And Species Distribution Of A Forested Watershed In The Northern Cumberland Plateau, Katherine J. Love

Theses and Dissertations--Forestry and Natural Resources

Spatial patterns of moisture and tree species have been studied using environmental gradients, often represented by terrain attributes in GIS. With climate change, GIS terrain variables, which are static as long as the elevation remains unchanged, will not reflect alterations in temperature, water cycle, and atmospheric conditions. In this thesis, the commonly used terrain variables and climate water balance variables were evaluated and compared for their ability to explain soil moisture and tree species distributions in a forested watershed in the Northern Cumberland Plateau. The results suggest that GIS terrain variables generally perform better than climate water balance variables, however, …

Ecological Studies Of An Abyssal Nodule Province To Inform The Management Of Deep-Sea Mining, Kirsty Alexandra Mcquaid

School of Biological and Marine Sciences Theses

The abyssal environment remains one of the most poorly studied parts of the planet. While predominantly an environment dominated by soft sediments, some abyssal regions are known to harbour potato-sized, rock-like formations known as polymetallic nodules. These nodule provinces are now the subject of exploration by nations and their nominated contractors keen to develop a new deep-sea mining industry. This new industry has the potential for large-scale environmental impacts, but at present these impacts are difficult to predict, and therefore mitigate, as a result of the lack of ecological data and scientific understanding of these areas. The studies carried out …

Postmortem Interval Estimation Based On Eukaryotic Community Associated With Soil Under Decomposing Porcine Remains, Amanda M. Haase

Master of Science in Forensic Science Directed Research Projects

Recent studies have shown that bacteria associated with soils under a carcass change significantly both temporally and spatially. These studies were done in both laboratory and field conditions, but with limited replications. In addition, limited information exists on temporal and spatial changes in eukaryotic community structure associated with soil under decomposing remains. This study was designed to fill in these gaps and expand on previous studies to improve postmortem interval (PMI) estimation techniques as well as to identify cadaver decomposition islands (CDI) based on eukaryotic community structure associated with soil under vertebrate remains. To accomplish this goal, soil samples were …

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 …

Imputation Of Missing Data From Time-Lapse Cameras Used In Recreational Fishing Surveys, Ebenezer Afrifa-Yamoah, Stephen M. Taylor, Aiden Fisher, Ute Mueller

Research outputs 2014 to 2021

While remote camera surveys have the potential to improve the accuracy of recreational fishing estimates, missing data are common and require robust analytical techniques to impute. Time-lapse cameras are being used in Western Australia to monitor recreational boating activities, but outages have occurred. Generalized linear mixed effect models formulated in a fully conditional specification multiple imputation framework were used to reconstruct missing data, with climatic and some temporal classifications as covariates. Using a complete 12-month camera record of hourly counts of recreational powerboat retrievals, data were simulated based on ten observed camera outage patterns, with a missing proportion of between …
