This study investigates the relationship between multiple temperature variables, to include annual and pre-lay date temperatures with first-egg and mean first-egg lay dates of the eastern bluebird at the Warner Parks in Nashville, Tennessee, USA. Data is collected by citizen scientists for the Eastern Bluebird Nesting Box Project while visiting artificial nest boxes throughout the park and recording observations made during the breeding season. Temperature data is retrieved from the Northwest Alliance for Computational Science and Engineering’s Parameter-elevation Regressions on Independent Slopes Model (PRISM) Climate Group, based at Oregon State University. The analyses showed no correlation between annual or pre-lay …


Effect Of Climate Change On Lyme Disease Cases In 4 New Jersey Counties, Meredith Olson Dec 2020

Effect Of Climate Change On Lyme Disease Cases In 4 New Jersey Counties, Meredith Olson

Capstone Experience: Master of Public Health

Since its discovery more than 40 years ago, there has been an increasing occurrence of Lyme disease. Lyme disease is a tick-borne illness found predominantly in the Northeastern region of the United States. Studies have shown that environmental factors play an important role on the life cycle of ticks. Due to the complexity of environmental changes as well as the life cycle of different tick species, the variety of factors that could influence the increase in Lyme disease can be different depending on tick species and region. This study compared different regions of New Jersey, a highly Lyme disease endemic …


Effects Of Climate Change On The Epidemiology Of Flood-Related Waterborne Disease: A Systematic Literature Review, Sarah M. Cadarette Dec 2020

Effects Of Climate Change On The Epidemiology Of Flood-Related Waterborne Disease: A Systematic Literature Review, Sarah M. Cadarette

Capstone Experience: Master of Public Health

Natural disasters, such as flooding related to extreme precipitation, can lead to many adverse health effects (i.e. waterborne disease). Several outbreaks of waterborne disease have been linked to extreme precipitation, and gastrointestinal infection has been shown to increase after floods. Climate change is likely to lead to a higher frequency of waterborne disease through increases in extreme precipitation and associated flooding affecting water and sanitation infrastructure. This review sought to answer 2 research questions: 1. Has the epidemiology of waterborne disease related to floods changed over time? 2. Can this difference be related to climate change? A literature search was …


Collaboration And Reflexivity In Wildland Fire Risk Governance In The Western United States, Brett Alan Miller Dec 2020

Collaboration And Reflexivity In Wildland Fire Risk Governance In The Western United States, Brett Alan Miller

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This dissertation presents both quantitative and qualitative analysis on different aspects of wildland fire risk management in the western United States. Each of these chapters is framed by and examines the sociological concept of reflexivity, which describes a process of individual and/or collective reflection. This reflexivity is needed to identify and enact alternative management strategies that contend with the expected increases in the number and severity of wildland fires in the future due to the combined effects of even-aged forest growth after years of timber extraction, a legacy of fire suppression, climate change, and increasing human development in the wildland-urban …


Phenotypic Responses Of Sagebrush To The Southwestern North America Megadrought: A Genotype-By-Environment (Gxe) Approach, Kara A. Navock Dec 2020

Phenotypic Responses Of Sagebrush To The Southwestern North America Megadrought: A Genotype-By-Environment (Gxe) Approach, Kara A. Navock

Boise State University Theses and Dissertations

The Southwestern North America megadrought is an extreme climate event. Artemisia tridentata (big sagebrush) is the dominant, keystone species of sagebrush-steppe ecosystems in arid and semi-arid habitats of western North America. I conducted a genotype-by-environment (GxE) experiment on two putative genotypes (drought-tolerant, G1 and drought-sensitive, G2) and two cytotypes, diploid (2x) and tetraploid (4x), to determine the phenotypic responses of big sagebrush seedlings to drought. For three chlorophyll fluorescence parameters, my results indicate a complex set of factors influence sagebrush responses to drought, including canalization, adaptive phenotypic plasticity, cryptic genetic diversity, and GxE interactions. Variation in leaf temperature profiles of …


Environmental Controls On Didymosphenia Geminata Bloom Formation, Lindsay Capito Dec 2020

Environmental Controls On Didymosphenia Geminata Bloom Formation, Lindsay Capito

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Climate change is causing rapid glacial recession and earlier snowmelt, which alter the physical and chemical properties of rivers. As a result, organisms at the base of the food web are responding in unforeseen ways. We use the nuisance algae D. geminata (Didymo) as a case study for how climate induced shifts in the timing of glacial and snowmelt runoff are affecting river ecosystems. We evaluated how shifts in the timing of nutrient concentrations and light availability affect nuisance blooms of Didymo in three complementary ways. These are, field studies across streams in various stages of glacial recession, weekly measurements …

Inoculum Potential Of Pinus Edulis-Associated Ectomycorrhizal Fungi Across A Forest Extirpation Chronosequence, Annie M. Montes Nov 2020

Inoculum Potential Of Pinus Edulis-Associated Ectomycorrhizal Fungi Across A Forest Extirpation Chronosequence, Annie M. Montes

Biology ETDs

Few studies have examined inoculum potential of ectomycorrhizal fungi (EMF) in the absence of plant hosts, yet persistence of these fungi may be paramount to resilience of Pinus edulis and other mycorrhizal plant species. We conducted a study in which seven sites were selected in northwestern New Mexico with known dates of P. edulis extirpation and a lack of regeneration. Age classes included: two sites extirpated 10-20 years ago, two extirpated 55-65 years ago, two extirpated 500+ years ago, and one extirpated 11,000+ years ago. At each site, two plots were paired: an extirpated plot and the nearest live adult …

Although natural resource managers are concerned about climate change, many are unable to adequately incorporate climate change science into their adaptation strategies or management plans, and are not always aware of or do not employ the most current scientific knowledge. One of the most prominent natural resource management agencies in the United States is the Bureau of Land Management (BLM), which is tasked with managing over 248 million acres (>1 million km2) of public lands for multiple, often conflicting, uses. Climate change will affect the sustainability of many of these land uses and could further increase conflicts …

Using Stable Isotope ( 13c) And C/N Ratio To Study The Effects Of Climate Change On Olive Trees, Rezq Basheer-Salimia

Journal of the Arab American University مجلة الجامعة العربية الامريكية للبحوث

In this research, the impact of some climate change effects on the olive tree was studied. Specifically, the research investigated the impact of the lack of water and drought on the physiology of olive trees using stable carbon isotopic (Delta13C) and C/N ratios. Four olive cultivars including Souri, Roomi, Improved-Nabali, and Nasouhi, planted in three geographical areas with different rainfall patterns were used. These locations are Yatta/Hebron area (dry and low rainfall area with less than 300 mm/year), Jab’a/Jerusalem area (semi-dry and medium rainfall zone), in addition to the Kufer Ra’e/Jenin area (area of high rainfall, higher than 550 mm/year). …


Spatial Fingerprint Of Younger Dryas Cooling And Warming In Eastern North America, David Fastovich, James M. Russell, Stephen T. Jackson, Teresa R. Krause, Shaun A. Marcott, John W. Williams Oct 2020

Spatial Fingerprint Of Younger Dryas Cooling And Warming In Eastern North America, David Fastovich, James M. Russell, Stephen T. Jackson, Teresa R. Krause, Shaun A. Marcott, John W. Williams

Faculty Authored Articles

The Younger Dryas (YD, 12.9–11.7 ka) is the most recent, near‐global interval of abrupt climate change with rates similar to modern global warming. Understanding the causes and biodiversity effects of YD climate changes requires determining the spatial fingerprints of past temperature changes. Here we build pollen‐based and branched glycerol dialkyl glycerol tetraether‐based temperature reconstructions in eastern North America (ENA) to better understand deglacial temperature evolution. YD cooling was pronounced in the northeastern United States and muted in the north central United States. Florida sites warmed during the YD, while other southeastern sites maintained a relatively stable climate. This fingerprint is …

Spatial And Temporal Dynamics Of Human–Wildlife Conflicts In The Kenya Greater Tsavo Ecosystem, Joseph M. Mukeka, Joseph O. Ogutu, Erustus Kanga, Eivin Røskaft

Human–Wildlife Interactions

Biodiversity conservation in developing countries is faced with many and mounting challenges, including increasing human–wildlife conflicts (HWCs). In Africa and other developing countries, increasing HWCs, particularly those adjacent to protected areas, can adversely affect local stakeholder perceptions and support for conservation. We analyzed HWC reports for multiple wildlife species compiled >23 years (1995–2017) from the Greater Tsavo Ecosystem (GTE) in Kenya to determine HWC trends. The GTE is the largest protected area in Kenya, covering 22,681 km2. Overall, 39,022 HWC incidents were reported in 6 GTE regions (i.e., Taveta, Mutomo, Kibwezi, Rombo, Galana, Bachuma). The 5 wildlife species …


Ocean Acidification Mitigates The Negative Effects Of Increased Sea Temperatures On The Biomineralization And Crystalline Ultrastructure Of Mytilus, Antony M. Knights, Matthew J. Norton, Anaëlle J. Lemasson, Natasha Stephen Oct 2020

Ocean Acidification Mitigates The Negative Effects Of Increased Sea Temperatures On The Biomineralization And Crystalline Ultrastructure Of Mytilus, Antony M. Knights, Matthew J. Norton, Anaëlle J. Lemasson, Natasha Stephen

School of Biological and Marine Sciences

Negative impacts of global climate change are predicted for a range of taxa. Projections predict marked increases in sea surface temperatures and ocean acidification (OA), arguably placing calcifying organisms at most risk. While detrimental impacts of environmental change on the growth and ultrastructure of bivalve mollusk shells have been shown, rapid and diel fluctuations in pH typical of coastal systems are often not considered. Mytilus edulis, an economically important marine calcifier vulnerable to climate change, were exposed to current and future OA (380 and 1000 ppm pCO2), warming (17 and 20°C), and ocean acidification and warming (OAW) scenarios …


Determination And Assessment Of The Spatio-Temporal Changing Dynamics In The Groundwater Level And Mineralization In Irrigated Areas Under Climate Change (As An Example Of Syrdarya Province), S. Khasanov, S. Adilov, R. Kulmatov Oct 2020

Determination And Assessment Of The Spatio-Temporal Changing Dynamics In The Groundwater Level And Mineralization In Irrigated Areas Under Climate Change (As An Example Of Syrdarya Province), S. Khasanov, S. Adilov, R. Kulmatov

Irrigation and Melioration

In the irrigated lands of the Aral Sea Basin, salinization processes are taking place as a result of rising groundwater levels and increasing its mineralization due to the unsustainable use of water and land resources. This, in turn, leads to the withdrawing of arable land and a decrease in crop yields. This is especially the case in the irrigated areas of the lower reaches of the Amudarya and Syrdarya rivers, located in Uzbekistan, southern Kazakhstan, and Turkmenistan. This research was aimed to learn and evaluate the long-term changing behavior of groundwater level and mineralization in the irrigated areas of the …


Gene Expression Responses Of Larval Gopher (Sebastes Carnatus) And Blue (S. Mystinus) Rockfish To Ocean Acidification And Hypoxia, Jacoby Baker Oct 2020

Gene Expression Responses Of Larval Gopher (Sebastes Carnatus) And Blue (S. Mystinus) Rockfish To Ocean Acidification And Hypoxia, Jacoby Baker

Capstone Projects and Master's Theses

Global climate change is driving shifts in ocean chemistry, which combined with intensification of coastal upwelling, reduces ocean pH and dissolved oxygen (DO) content in the nearshore habitats of the California Current System. Physiological plasticity, within and across generations, might be especially important for long-lived, late-to-mature species, like rockfishes (genus Sebastes), that may be unable to keep pace with climate change via genetic adaptation. Rockfishes exhibit matrotrophic viviparity and may be able to buffer their offspring from environmental stress through early developmental exposure or transgenerational plasticity (non-genetic inheritance of phenotypes). In this study, mature female gopher (S. carnatus …
