Molecular Markers Of Climate Adaptation Of Thysanoessa Longicaudata (Euphausiacea) In The Arctic, Alexandra Frenzel

Honors Scholar Theses

This study uses molecular approaches to investigate evidence of climate adaptation of a marine zooplankton species in the Arctic Ocean. Euphausiids (krill) are abundant and ecologically important members of the ocean ecosystems and play key roles in pelagic food webs. The specific goal is to analyze patterns of gene expression, which is measured as RNA concentration for all genes across the entire transcriptome and also for specific target genes of known function, for the euphausiid Thysanoessa longicaudata. Gene expression can reveal responses to thermal stress associated with exposure to temperatures outside the normal range for the species. Specimens of T. …

Dataset For Golden Eagle Dietary Shifts Following Wildfire And Shrub Loss Have Negative Consequences For Nestling Survivorship, Julie A. Heath, Mike Kochert, Karen Steenhof

Biological Sciences Data

Wildfires and invasive species have caused widespread changes in western North America's shrub-steppe landscapes. The bottom-up consequences of degraded shrublands on predator ecology and demography remain poorly understood. We used a before-after paired design to study whether Golden Eagle (Aquila chrysaetos) diet and nestling survivorship changed following wildfires in southwestern Idaho, USA. We assessed burn extents from 1981 – 2013 and vegetation changes between 1979 (pre-burn) and 2014 (post-burn) within 3 km of Golden Eagle nesting centroids. We measured the frequency and biomass of individual prey, calculated diet diversity indexes, and monitored nestling survivorship at 15 territories in 1971 – …

More Than Stories: Indigenous Environmental Reciprocity In The Poetry Of Kathy Jetñil-Kijiner, Rebecca Purse

Theses and Dissertations

This thesis brings to the forefront the traditional stories Marshallese poet, performer, and climate change activist Kathy Jetñil-Kijiner shares in her published poetry. Indigenous studies scholars agree that Indigenous stories have power--power to change, power to inform, and power to heal. The traditional stories in Jetñil-Kijiner's poetry reveal the power of the environment and the potential relationships that can exist between humans and natural beings. While these traditional stories work to disrupt the narrative that Indigenous perspectives, knowledges, and cultures are somehow inferior to their colonial neighbors', they also assert the need for a return to environmental reciprocit--or the establishment …

Temperature Regulation Of Plant Hormone Signaling During Stress And Development, Christian Castroverde, Damaris Dina

Biology Faculty Publications

Global climate change has broad-ranging impacts on the natural environment and human civilization. Increasing average temperatures along with more frequent heat waves collectively have negative effects on cultivated crops in agricultural sectors and wild species in natural ecosystems. These aberrantly hot temperatures, together with cold stress, represent major abiotic stresses to plants. Molecular and physiological responses to high and low temperatures are intricately linked to the regulation of important plant hormones. In this review, we shall highlight our current understanding of how changing temperatures regulate plant hormone pathways during immunity, stress responses and development. This article will present an overview …

Coral Bleaching Response Is Unaltered Following Acclimatization To Reefs With Distinct Environmental Conditions, Katie L. Barott, Ariana S. Huffmyer, Jennifer M. Davidson, Elizabeth A. Lenzb, Shayle B. Matsuda, Joshua R. Hancock, Teegan Innis, Crawford Drury, Hollie M. Putnam, Ruth D. Gates

Biological Sciences Faculty Publications

Urgent action is needed to prevent the demise of coral reefs as the climate crisis leads to an increasingly warmer and more acidic ocean. Propagating climate change-resistant corals to restore degraded reefs is one promising strategy; however, empirical evidence is needed to determine whether stress resistance is affected by transplantation beyond a coral's native reef. Here, we assessed the performance of bleaching-resistant individuals of two coral species following reciprocal transplantation between reefs with distinct pH, salinity, dissolved oxygen, sedimentation, and flow dynamics to determine whether heat stress response is altered following coral exposure to novel physicochemical conditions in situ. Critically, …

An Analysis Of The Impacts Of Climate Change On Food Security In The Albertine Rift Of East Africa, Malcolm Jacob

Sustainability and Social Justice

As one of the most densely populated regions on the continent of Africa, the Albertine Rift (consisting of parts of Rwanda, Uganda, and the eastern DRC) faces ongoing problems providing enough food for its people through crop production, livestock husbandry, and other forms of food production. Even more troubling for the future is that anthropogenic climate change is expected to significantly exacerbate food insecurity. This paper addresses one central question: how will climate change impact food security in the Albertine Rift? Based on an analysis of available data, this paper finds that policymakers should listen closely to local farmers and …

Sustainability and Social Justice

This paper presents a sustainable adaptive capacity framework for water management for municipalities, named Sustainable MAC-Water framework, after assessing the strengths and weaknesses of adaptive capacity in Mexico and its municipalities. It provides municipalities with an instrument to help them create sustainable adaptive capacity plans (Sustainable MAC plans) to prevent adverse impacts on water resources and related sectors. It is based on a study of policy instruments crafted by the Intergovernmental Panel on Climate Change (IPCC) and the Government of Mexico, and literature on adaptive capacity, assessment, and planning. The Sustainable MAC-Water framework recommends the establishment of a Reactive Barriers …

Reimagining Exceptional Events: Regulating Wildfires Through The Clean Air Act, Emily Williams

Washington Law Review

Wildfires are increasing in both frequency and severity due to climate change. Smoke from these fires causes serious health problems. Land managers agree that prescribed burns help mitigate these negative consequences. Prescribed burns are lower-intensity fires that are intentionally ignited and managed for an ecological benefit. They reduce the amount of smoke produced and limit wildfire damage to natural systems and human property.

The Clean Air Act (CAA) is designed to regulate air pollution to protect public health, yet it exempts wildfire smoke through the exceptional events designation while imposing strict regulations on prescribed burns. Congress and the Environmental Protection …

Aim: Modelling African great ape distribution has until now focused on current or past conditions, while future scenarios remain scarcely explored. Using an ensemble forecasting approach, we predicted changes in taxon-specific distribution under future scenarios of climate, land use and human populations for (1) areas outside protected areas (PAs) only (assuming complete management effectiveness of PAs), (2) the entire study region and (3) interspecies range overlap. Location: Tropical Africa. Methods: We compiled occurrence data (n = 5,203) on African apes from the IUCN A.P.E.S. database and extracted relevant climate-, habitat- and human-related predictors representing current and future (2050) conditions to …

The Arctic is experiencing rapid climate change. This research documents tundra vegetation changes near Atqasuk and Utqiaġvik, Alaska. At each location, 30 plots were sampled annually from 2010 to 2019 using a point frame. For every encounter, we recorded the height and classified it into eight groupings (deciduous shrubs, evergreen shrubs, forbs, graminoids, bryophytes, lichens, litter and standing dead vegetation); for vascular plants we also identified the species. We found an increase in plant stature and cover over time consistent with regional warming. Graminoid cover and height increased at both sites, with a fivefold increase in cover in Atqasuk. At …

Social Psychology Of Climate Change In The Asian Context: Introduction To Special Issue, Kim-Pong Tam, Angela K. Y. Leung, Susan Clayton

Research Collection School of Social Sciences

Climate change is one of the biggest challenges facing many countries in the Asia Pacific. Asia as a whole is a primary contributor to carbon emissions. According to the BP Statistical Review of World Energy 2020, the Asia Pacific region alone accounts for more than half of the world’s total greenhouse gas emissions. This represents an increase in consumption of oil, gas, and coal in Asia Pacific from 44.5% in 2009 to 50.5% in 2019. According to the review, compared to the rest of the world, Asia Pacific had the highest growth rate (2.7%) of carbon emissions between 2008 and …

Successful Long-Distance Breeding Range Expansion Of A Top Marine Predator, Robert William Henry, Scott A. Shaffer, Michelle Antolos, María Félix-Lizárraga, David G. Foley, Elliott L. Hazen, Yann Tremblay, Daniel P. Costa, Bernie R. Tershy, Donald A. Croll

Faculty Research, Scholarly, and Creative Activity

Little is known about the effects of large-scale breeding range expansions on the ecology of top marine predators. We examined the effects of a recent range expansion on the breeding and foraging ecology of Laysan albatrosses (Phoebastria immutabilis). Laysan albatrosses expanded from historical breeding colonies in the Central Pacific Ocean to the Eastern Pacific Ocean around central Baja California, Mexico, leading to a 4,000-km shift from colonies located adjacent to the productive transition zone in the Central Pacific to colonies embedded within the eastern boundary current upwelling system of the Eastern Pacific California Current. We use electronic tagging and remote …

Ideas And Perspectives: Biogeochemistry – Some Key Foci For The Future, Thomas S. Bianchi, Madhur Anand, Chris T. Bauch, Donald E. Canfield, Luc De Meester, Katja Fennel, Peter M. Groffman, Michael L. Pace, Mak Saito, Myrna N J. Simpson

Advanced Science Research Center

Biogeochemistry has an important role to play in many environmental issues of current concern related to global change and air, water, and soil quality. However, reliable predictions and tangible implementation of solutions, offered by biogeochemistry, will need further integration of disciplines. Here, we refocus on how further developing and strengthening ties between biology, geology, chemistry, and social sciences will advance biogeochemistry through (1) better incorporation of mechanisms, including contemporary evolutionary adaptation, to predict changing biogeochemical cycles, and (2) implementing new and developing insights from social sciences to better understand how sustainable and equitable responses by society are achieved. The challenges …

Should Mangrove Forests Be Used As Coastal Protection For The Gulf Of Mexico From Future Climate Effects: A Look At The Houston Galveston Area., Benjamin L. Weldon

Master's Projects and Capstones

Climate change effects pose a major threat to coastal cities. Sea-level rise and an increase in hurricane intensity will increase the need for protection for these communities. Wetland ecosystems provide key protective services to the cities that lie behind them. Mangroves are a coastal wetland with benefits such as wave attenuation, carbon sequestration, and shoreline management. Mangrove’s habitat range will expand northward as climate change progresses. With a 2-4°C increase in winter temperature extremes black mangroves are projected to be able to inhabit the entire coast of the Gulf of Mexico. The viability of using mangrove forests as future protection …

Microbial Evolution Of Cryosphere And Biosecurity Concerns, Jingyang Xu, Qianggong Zhang, Yi Shi

Bulletin of Chinese Academy of Sciences (Chinese Version)

The unique and extreme ecological environment of cryosphere acts as a gigantic reservoir of microorganisms, which preserves precious records of the diversity and evolutionary history of ancient microbes. Climate change and human activities have made significant impacts on the ecological system. Global warming causes melting of the cryosphere that remained frozen for thousands of years and releases microorganisms, some of them are recovered to life and constitute a potential threat to the ecological environment and human health. It is urgent to combine multidisciplinary research forces to investigate the microbial ecology of cryosphere, analyze the microbe pathogenesis and transmission mechanisms, as …

The Role Of Climate Change, Wildfire And Human Interference In The Potential Spread Of Sin Nombre Hantavirus In North America, Margarita Miglio

Master's Projects and Capstones

Sin Nombre hantavirus is a rare rodent-borne pathogen that causes Hantavirus Cardiopulmonary Syndrome (HCPS), a disease with a 35% fatality rate in humans. The main rodent host of Sin Nombre hantavirus is the deer mouse (Peromyscus maniculatus), one of the most prolific, best studied and highly adaptable rodent species in North America. Deer mice are hyper-reservoirs, carrying Sin Nombre virus, plague (Yersinia pestis) and the Peromyscus species carry Lyme disease. Although deer mice have been shown to react positively to wildfire, current assessments of Sin Nombre hantavirus risk to humans and climate change do not consider …

Testing The Climatic Variability Hypothesis With Coastal And Inland Populations Of Mimulus Guttatus And Implications For These Populations Under Climate Change, Alec Chiono

Master's Theses

How climate shapes the niche of a species is a core interest in evolution and ecology. Research on the evolution of climatic niches can inform us on the historical relationship between organisms and their climate, and, in an era of great environmental change, what that relationship may look like in the future. In this study, I tested an essential idea in the history of climate niche research, the Climatic Variability Hypothesis, by comparing the thermal niche breadth of coastal and inland populations of Mimulus guttatus. Using thermal performance results from this experiment, I also forecasted how the suitability of …

The Changing Face Of Winter: Lessons And Questions From The Laurentian Great Lakes, Ted Ozersky, Andrew J. Bramburger, Ashley K. Elgin, Henry A. Vanderploeg, Jia Wang, Jay A. Austin, Guy Meadows, Et. Al.

Michigan Tech Publications, Part 1

Among its many impacts, climate warming is leading to increasing winter air temperatures, decreasing ice cover extent, and changing winter precipitation patterns over the Laurentian Great Lakes and their watershed. Understanding and predicting the consequences of these changes is impeded by a shortage of winter-period studies on most aspects of Great Lake limnology. In this review, we summarize what is known about the Great Lakes during their 3–6 months of winter and identify key open questions about the physics, chemistry, and biology of the Laurentian Great Lakes and other large, seasonally frozen lakes. Existing studies show that winter conditions have …

Intangible Cultural Heritage: A Benefit To Climate-Displaced And Host Communities, Gül Aktürk, Martha B. Lerski

Publications and Research

Climate change is borderless, and its impacts are not shared equally by all communities. It causes an imbalance between people by creating a more desirable living environment for some societies while erasing settlements and shelters of some others. Due to floods, sea level rise, destructive storms, drought, and slow-onset factors such as salinization of water and soil, people lose their lands, homes, and natural resources. Catastrophic events force people to move voluntarily or involuntarily. The relocation of communities is a debatable climate adaptation measure which requires utmost care with human rights, ethics, and psychological well-being of individuals upon the issues …

The Potential Influence Of Abiotic Conditions On Mussel Species Abundance In San Francisco Bay, Alexandra G. Farrell, M. Christina Vasquez Dr.

Honors Thesis

Climate change has negatively altered seawater conditions, which may have severe implications for marine ecosystems. Mussels are susceptible to environmental changes since they are primary consumers and filter-feeding bivalves. Two species of particular interest to the West Coast of the U.S. are Mytilus galloprovincialis and M. trossulus. M. trossulus is native to the California Coast and was historically prevalent from Southern California to Washington. However, with increased shipping and rising seawater temperature, M. galloprovincialis, an invasive species from the Mediterranean, pushed the species range of M. trossulus poleward. M. trossulus is more tolerant of cold seawater with variable salinity while …

Ecosystems across the United States are changing in complex ways that are difficult to predict. Coordinated long-term research and analysis are required to assess how these changes will affect a diverse array of ecosystem services. This paper is part of a series that is a product of a synthesis effort of the U.S. National Science Foundation’s Long Term Ecological Research (LTER) network. This effort revealed that each LTER site had at least one compelling scientific case study about “what their site would look like” in 50 or 100 yr. As the site results were prepared, themes emerged, and the case …

Circadian Rhythms In Legumes: What Do We Know And What Else Should We Explore?, Hazel Marie Kugan, Nur Ardiyana Rejab, Nurul Amylia Sahruzaini, Jennifer Ann Harikrishna, Niranjan Baisakh, Acga Cheng

Faculty Publications

The natural timing devices of organisms, commonly known as biological clocks, are composed of specific complex folding molecules that interact to regulate the circadian rhythms. Circadian rhythms, the changes or processes that follow a 24‐h light–dark cycle, while endogenously programmed, are also influenced by environmental factors, especially in sessile organisms such as plants, which can impact ecosystems and crop productivity. Current knowledge of plant clocks emanates primarily from research on Arabidopsis, which identified the main components of the circadian gene regulation network. Nonetheless, there remain critical knowledge gaps related to the molecular components of circadian rhythms in important crop groups, …

Particle Tracking Reveals Pelagic Red Crabs As Indicators Of Climate-Driven Range Expansion In The California Current, Elizabeth Saraf

Senior Honors Projects

Since their first recorded occurrence in 1859, Pelagic Red Crabs (PRC; Pleuroncodes planipes) have experienced increased frequency of episodic mass stranding events in the Eastern Pacific Ocean. PRC’s are transported over 1,000 km northward of their central domain from the coast of central Baja California, Mexico. They have been reported by the thousands on the beaches of central and southern California. Their presence influences the surrounding ecosystem and commercial fisheries because they are nutritional prey items and large predators change their diet to incorporate PRC’s when they are available. Seasonal coastal currents and the California Undercurrent transport warmer waters …

Climate-Driven Impacts On Himalayan Aquatic Biodiversity: A Case Study Involving Snowtrout (Cyprinidae: Schizothorax), Riri Wiyanti Retnaningtyas

Graduate Theses and Dissertations

Monitoring biodiversity, to include its relative dispersal and contraction, has become a conservation task of great importance, particularly given the catastrophic and ongoing loss of habitat due to climate change. However, the timing, direction, and magnitude of these rates vary across taxa and ecosystems. Predicting specific impacts of climate change can thus be difficult and this, in turn, hampers management action. Metrics are needed to not only quantify contemporary requirements of species, but also predict potential distributions that fluctuate in lockstep with climate.

Montane ecosystems in the Himalayas are highly impacted by climate change, yet remain largely understudied due to …

Major League Baseball Fans’ Climate Change Attitudes And Willingness To Adapt: Climate Vulnerability Vs. America’S Pastime., Jessica R. Murfree

Electronic Theses and Dissertations

Climate change threatens the ability to enjoy sport around the world, including in the United States. While the scientific community reached consensus regarding the presence and severity of climate change near the turn of the twenty-first century, that same agreement has not been met across the American general public. Major League Baseball (MLB) is particularly vulnerable to climate change in the U.S. due to its season duration, geographic footprint, and largely outdoor nature. Therefore, the purpose of this study was to investigate relationships between U.S.-based MLB fans’ sport identification and their climate change attitudes, perceptions of climate change risk, and …

An Assessment Of The Use Of Green Stormwater Infrastructure For Flood Mitigation At Berry Brook, Rachel Lynn Hastings

Master's Theses and Capstones

This research examined the effectiveness of GSI and other BMPs to control urban flooding for extreme precipitation events and compared the impacts of increasing impervious cover with the impacts of increasing rainfall intensity caused by climate change. The City of Dover has spent the last decade implementing best management practices in the 185-acre Berry Brook watershed to combat stream pollution and flooding caused by urbanization. Improvements to the watershed included building additional headwater wetland area, daylighting and restoring 1,100 feet of stream, and redirecting stormwater to GSIs, thereby reducing the effective impervious cover from 30% to 10%. Four PCSWMM models …

Modeling Hydrochemical And Vegetation Responses Of High-Elevation Forested Watersheds To Future Climate And Atmospheric Deposition Changes In The Southeastern U.S., Hailong Huang

Dissertations

Changes in climate and atmospheric acidic deposition alter biogeochemical cycles in forested ecosystems. I investigated the responses of vegetation, soil, and hydro-related processes to changes in climate and acidic deposition at five high-elevation forests in the southeastern U.S. using a biogeochemical model - PnET-BGC model. I focused on change-points and thresholds concepts that were less studied in forest ecosystems as well as seasonal variability of responses and extreme events. I applied principal component analysis (PCA) to reduce the dimensionality of data. I developed a Bayesian multi-level model to derive key biogeochemical variables response to temperature and precipitation (local) and latitude …
