Phytoplankton Thermal Trait Parameterization Alters Community Structure And Biogeochemical Processes In A Modeled Ocean, Stephanie I. Anderson, Clara Fronda, Andrew D. Barton, Sophie Clayton, Tatiana A. Rynearson, Stephanie Dutkiewicz

OES Faculty Publications

Phytoplankton exhibit diverse physiological responses to temperature which influence their fitness in the environment and consequently alter their community structure. Here, we explored the sensitivity of phytoplankton community structure to thermal response parameterization in a modelled marine phytoplankton community. Using published empirical data, we evaluated the maximum thermal growth rates (μ_max) and temperature coefficients (Q₁₀; the rate at which growth scales with temperature) of six key Phytoplankton Functional Types (PFTs): coccolithophores, cyanobacteria, diatoms, diazotrophs, dinoflagellates, and green algae. Following three well-documented methods, PFTs were either assumed to have (1) the same μ_max and …

The Impact Of Climate Change On Environmental Sustainability And Human Mortality, Xingzhi Mara Chen, Andrew Sharma, Hua Liu

Political Science & Geography Faculty Publications

Climate dictates the critical aspects of human environmental conditions. The frequency and intensity of extreme weather conditions due to human-induced climate change have alarmingly increased. Consequently, climate change directly affects environmental sustainability and human mortality in the short term and creates prolonged and complicated long-term indirect grave risks. This paper examines three-level environmental impact risks associated with climate change on human mortality. It proposes a conceptual framework for developing an empirical event-based human mortality database related to climate change and communication strategies to enhance global environmental adaptation, resilience, and sustainability.

Implementing Nature's Rights In Colombia: The Arato And Amazon Experiences, Camila Bustos, Whitney Richardson

Elisabeth Haub School of Law Faculty Publications

Nature's rights approaches are being developed as an alternative legal means to enable justice for nature and, oftentimes, humans, too. This study examines Colombia's two seminal court-ordered nature's rights approaches which recognize ecosystems-the Atrato River Basin (2016) and the Colombian Amazon (2018)-as a legal subject with rights to protection, maintenance, conservation, and restoration. Developed as remedies for human rights violations, both cases offer opportunities to explore variations in nature's rights approaches and the relationship between efforts to enable justice for humans and nature. We build on existing scholarly engagement with the cases by contributing a detailed archival study on their …

Miniscule And Might Predators: A Cautionary Tale Of The Power Of Mosquitoes In California And The Greater United States, Benjamin Willett

Pitzer Senior Theses

This thesis investigates how the growth of mosquito populations within the United States, and California specifically, poses unique threats both to public health and socio- political conditions. Mosquito species that are native to the country, Anopheles punctipennis (An. Punctipennis) and Anopheles freeborni (An. freeborni) exist in a uniquely threatening position, bolstered by the introduction of invasive species (Ae. aegypti) and Aedes albopictus (Ae. albopictus). A focus on tracing introductions of invasive species and the resulting spread of zoonotic diseases such as yellow fever, dengue, and chikungunya are valuable indicators of how the insects are influenced by human actions. This relationship …

Distributional Ecology Of Noccaea Vesicaria In Relation To The Anatolian Diagonal, İlayda Dumlupinar, Hakan Gür, Bariş Özüdoğru

Turkish Journal of Botany

Anatolia is located at the intersection of three of the world's 36 biodiversity hotspots (the Caucasus, Irano-Anatolian, and Mediterranean Basin biodiversity hotspots) and has about 10,000 plant species, over 3000 of which are endemic. Among the many reasons for the astonishing biodiversity of Anatolia, one that stands out is the Anatolian Diagonal. Although the Anatolian Diagonal has long been recognized as a biogeographical boundary between Central and Eastern Anatolia, its exact functioning is still not well understood. Thus, in this study, our aims were 1) to assess the environmental barrier function of the Anatolian Diagonal for a plant species, Noccaea …

Changes In The Microbiome Of The Sea Anemone Exaiptasia Diaphana During Bleaching From Short-Term Thermal Elevation, Jamison R. Sydnor, Jamie Lopez, Gordon V. Wolfe, Lisa Ott, Cawa Tran

Biology: Faculty Scholarship

We examined the response of microbial communities in the model sea anemone Exaiptasia diaphana (Aiptasia) to short-term thermal elevation. Through 16S rRNA gene sequencing, we characterized the microbiomes of symbiotic (with algal symbionts) and aposymbiotic (bleached) anemones under ambient (27°C) and heat-stressed (34°C) conditions for 8-10 days, using both replicated endpoint and non-replicated time-course approaches. Consistent with prior studies, we observed a stable abundance of bacteria from the families Alteromonadaceae and Rhodobacteraceae, though with wide variation among individual anemones. We observed that symbiotic state conferred a larger impact on the microbiome than heat stress, implying the microbiome may play a …

Seasonal Variations In Circumpolar Deep Water Intrusions Into The Ross Sea Continental Shelf, Yufei Wang, Meng Zhou, Zhaoru Zhang, Michael S. Dinniman

CCPO Publications

Intrusions of the warm and nutrient-rich Circumpolar Deep Water (CDW) across the Ross Sea shelf break play an important role in providing heat for ice shelf basal melting and setting the physical environment for biochemical processes. Several mechanisms driving CDW intrusions into the Ross Sea were proposed such as mesoscale eddies, tidal rectification, and interactions between Antarctic Slope Current (ASC) and topographic features. The seasonal variations in the poleward transport of CDW are investigated using ERA-Interim wind data and a Ross Sea circulation model based on the Regional Ocean Modeling System (ROMS) between September 1999 and September 2014. The analyses …

The Effects Of Warming Rate On The Thermal Tolerance Of A Southern Population Of Striped Bass (Morone Saxatilis), James Barrett

Honors College Theses

Climate change and global warming is an ever-growing concern for our environment and the survivability of the animals which inhabit it. With water temperatures expected to rise 2-3℃ in the next century, many aquatic organisms may be limited in their habitats based on their thermal tolerance (Lleras 2019). Southern populations of striped bass (Morone saxatilis) in the Southeastern United States could be some of the hardest hit by the effects of climate change due to their unusual life history as compared to the more northern populations of striped bass. These southern striped bass do not engage in coastal …

In recent years the effects of climate change have taken a devastating toll on ecosystems around the world. With high temperatures and extreme droughts, wildfires have become increasingly common. In order to combat these natural disasters wildland firefighters, drop millions of gallons of fire retardant on public lands and forests. These fire retardants consist of between 80%-100% ammonium phosphate which are incredibly effective as fire suppressants yet is more commonly known for its use in fertilizer. Ammonium phosphate fertilizers can lead to stream eutrophication and undesirable environmental impacts. Our research aims to address the effects of fire retardant on growth …

From The United States To Pakistan: Can Climate Change Pave Toe Way For An International Right To Animal Rescue In Disasters?, Altamush Saeed

Animal Law Review

Over 69% of the world’s wildlife has been lost between 1970 and 2018. Catastrophic events like the Australian bushfires, the Amazon rainforest fires, and the ongoing floods in the United States have led to the deaths of several billion animals. Ongoing apocalyptic floods have put one-third of Pakistan underwater and led to the deaths of over a million livestock animals. Climate change, human rights, and animal rights have become so intertwined that all life—including human, nonhuman, and plant life—is on the brink of extinction.

Grieving Climate Change: A Psychological And Personal Exploration Of Emotionally Processing The Climate Crisis, Hava Chishti

Pitzer Senior Theses

The psychological concept of grief, although not typically associated with climate change, has strong applications to the emotional processing of climate change for human beings. Grief can be related to climate change in many ways, including the grief that individuals may feel over the anticipated loss of their future, losses that may be experienced due to climate-related disasters, and grief for the overall implications of anthropogenic climate change. A mixture of traditional literature analysis and creative nonfiction essays, which focus on personal narratives from interviews and the author’s experience, are used to outline the ways in which the psychology of …

Climate change affects timing of reproduction in many bird species, but few studies have investigated its influence on annual reproductive output. Here, we assess changes in the annual production of young by female breeders in 201 populations of 104 bird species (N = 745,962 clutches) covering all continents between 1970 and 2019. Overall, average offspring production has declined in recent decades, but considerable differences were found among species and populations. A total of 56.7% of populations showed a declining trend in offspring production (significant in 17.4%), whereas 43.3% exhibited an increase (significant in 10.4%). The results show that climatic changes …

The Walls At The Ends Of Empires: Towards A Political Ecology Of The Imperial Border, Benjamin Allen Stahnke

Antioch University Dissertations & Theses

This dissertation study investigates the intricate and complicated interplay between the border walls of imperial states, environmental change, and dispossession. Employing a multidisciplinary approach rooted in Political Ecology, and drawing on the theoretical frameworks of Social Metabolism, Social Kinetics, and Green History, the study is built around an analysis of two historical examples: the Roman border walls in the north of England (Hadrian’s Wall and the Antonine Wall), and the U.S.-Mexico border wall. The research uncovers two overarching conclusions: firstly, imperial border walls serve as discriminatory structures, targeting and segregating Indigenous populations while asserting control over Indigenous geographies; secondly, the …

Ascophyllum Nodosum Seaweed Extract Application As A Possible Mechanism For Mitigating Salt Stress In Soybeans (Glycine Max), Elena Hoang

Honors Program Theses

Soil salinity, an abiotic stressor associated with climate change effects, inhibits the normal growth and development of sensitive crop species. The excessive accumulation of salt ions in plant tissue induces oxidative stress, which is characterized by an increased production of reactive oxygen species (ROS) damaging plant organelles and disrupting normal metabolic functions. Seaweed extracts (SWE) may be a solution for mitigating the effects of salt stress on crop yield and quality, as they introduce bioactive ingredients that are able to regulate gene expression and enhance natural physiological processes in plants. However, the positive benefits of SWE applications differ between plant …

Experimental Design Of Open-Field Temperature And Precipitation Manipulation System To Simulate Summer Extreme Climate Events For Plants And Soils, Gwang Jung Kim, Heejae Jo, Hyeonji Kim, Min Seok Cho, Nam-Jin Noh, Hanna Chang, Hyung-Sub Kim, Yowhan Son

Turkish Journal of Agriculture and Forestry

Extreme climate events are expected to occur very frequently and intensively with climate change, and such extreme events can induce irreversible damage to plants and soils, as well as ecosystems. Accordingly, there is a need to understand the effects of extreme climate events on ecosystems. Here, we designed a temperature and precipitation manipulation system to simulate extreme climate events of heat, drought, and heavy rainfall. We constructed three soil surface temperature manipulation levels (control, 3 °C, and 6 °C increases) and three precipitation manipulation levels (control, drought, and heavy rainfall) with six replicates, and operated these from day of year …

Civil & Environmental Engineering Faculty Publications

Algae are capable of sequestering nutrients such as nitrates and phosphates from wastewater in the presence of sunlight and carbon dioxide (CO₂) to build up their body mass and help combat climate change. In the current study, we carried out different case studies to estimate the volume of algal biomass that could be produced annually using the rotating algal biofilm (RAB) method in three large-scale water resource recovery facilities (WRRFs) in Texas: Fort Worth, Dallas, and Houston. We calculated the total amount of lipids, carbohydrates, and proteins that could be fractionated from the algal biomass while using the …

What Kills The Virtually Immortal Palms Of The Florida Scrub?, Warren G. Abrahamson Ii

Faculty Journal Articles

Premise: Life span varies greatly across plants, with some species being capable of extreme longevity. Yet even long‐lived individuals are susceptible to climatic events, fire, and other challenges. We examined rare mortality events and their causes in two long‐lived palmettos over four decades. Methods: We monitored the survival of the clonal Serenoa repens and non‐clonal, Florida‐endemic Sabal etonia from 1981 to 2022 in four habitats along an elevational gradient within the globally imperiled Florida scrub ecosystem. We considered several challenges to palmetto survival, including extreme fires, shading due to lack of fire, droughts, periods of high precipitation, and possible pathogens. …

Disparate Population And Holobiont Structure Of Pocilloporid Corals Across The Red Sea Gradient Demonstrate Species-Specific Evolutionary Trajectories, Carol Buitrago-López, Anny Cárdenas, Benjamin C.C. Hume, Thierry Gosselin, Fabian Staubach, Manuel Aranda, Daniel J. Barshis, Yvonne Sawall, Christian R. Voolstra

Biological Sciences Faculty Publications

Global habitat degradation heightens the need to better understand patterns of genetic connectivity and diversity of marine biota across geographical ranges to guide conservation efforts. Corals across the Red Sea are subject to pronounced environmental differences, but studies so far suggest that animal populations are largely connected, excepting evidence for a genetic break between the northern-central and southern regions. Here, we investigated population structure and holobiont assemblage of two common pocilloporid corals, Pocillopora verrucosa and Stylophora pistillata, across the Red Sea. We found little evidence for population differentiation in P. verrucosa, except for the southernmost site. Conversely, S. …

Swinea, Kalaina Thorne, Sarit Truskey, Anna R. Armitage, Ronald Baker, Josh L. Breithaupt, Kyle C. Cavanaugh, Erik S. Yando, A. Randall Hughes, Et Al.

Biological Sciences Faculty Publications

Climate change is altering species’ range limits and transforming ecosystems. For example, warming temperatures are leading to the range expansion of tropical, cold-sensitive species at the expense of their cold-tolerant counterparts. In some temperate and subtropical coastal wetlands, warming winters are enabling mangrove forest encroachment into salt marsh, which is a major regime shift that has significant ecological and societal ramifications. Here, we synthesized existing data and expert knowledge to assess the distribution of mangroves near rapidly changing range limits in the southeastern USA. We used expert elicitation to identify data limitations and highlight knowledge gaps for advancing understanding of …

However there is no baseline record of the climate mitigation currently performed by the trees on Pomona’s campus through carbon storage. This study seeks to determine a current baseline quantity of carbon stored and sequestrated by Pomona’s trees as well as possible courses of climate mitigation for Pomona College to take. Initial information gathering was conducted through interviews with several stakeholders. This study was conducted using data collected prior to …

Interactions Among Climate, Fire, And Ecosystem Processes Across Multiple Spatial And Temporal Scales In Rocky Mountain Forests, Kyra Diane Clark-Wolf

Graduate Student Theses, Dissertations, & Professional Papers

Warmer and drier climate conditions over recent decades are contributing to widespread increases in fire activity across western North America. The combined impacts of changing climate and fire activity threaten to undermine the longstanding resilience of forest ecosystems to wildfires, potentially leading to ecological transformations. This context creates a pressing need to understand the direct effects of climate and wildfire on ecosystem processes, and how longer-term changes in climate, fire activity, and ecosystem processes interact to determine ecological trajectories.

This dissertation advances our understanding of the causes and ecosystem consequences of wildfire and changing fire regimes in northern Rocky Mountain …

Individual And Population Responses To Hydrologic Variability In A Headwater Stream Salamander, Madaline Cochrane

Graduate Student Theses, Dissertations, & Professional Papers

Understanding how organisms respond to environmental variability is a central goal in ecology – a goal made even more pressing by the herculean challenge global climate change presents to all organisms. Climate change is increasing the frequency and intensity of floods and droughts, which will likely have disproportionate effects on freshwater organisms. Many stream-associated species have multi-stage life histories. However, we lack an empirical understanding of life history and movement responses of these organisms to hydrologic disturbances, and how these responses may influence demographic rates. In my dissertation, I used a combination of growth, developmental, movement, and demographic data to …

Fine Root Respiration In Quercus Rubra Is Influenced By Multidimensional Trade-Offs In Root Trait Space, Emma L. Shedd

Dissertations, Master's Theses and Master's Reports

Economic theory is often applied to plant strategies, arguing that trade-offs exist between maximizing quick returns on investment within short lifespans or producing longer-lived tissues with slower returns. While these trade-offs are well-studied aboveground, their influence on belowground traits, including root respiration, remains unclear. Resource heterogeneity and symbioses with mycorrhizal fungi may complicate root trade-off axes beyond those predicted by economics theory alone. Investigating fine root trade-offs in Quercus rubra populations along a latitudinal gradient in the Midwest, USA, we identified two distinct axes of variation in root traits: one related to a potential “fungal symbiosis” trade-off and another representing …

Insect And Pest Management For Sustaining Crop Production Under Changing Climatic Patterns Of Drylands, Ruchika Kashyap, Sajjan Grover, Heena Puri, Sandeep Kaur, Jagmohan Singh, Karansher S. Sandhu, Gagandeep Kaur, Hinal Kharva, Shivreet Kaur, Balwinder Kaur

Department of Entomology: Faculty Publications

Climate change is alarming, particularly for agriculturists as it severely impacts the development, distribution, and survival of insects and pests, affecting crop production globally. Over time, climate change is drastically tumbling the crop productivity in all the cropping systems, whereas the dryland agriculture with existing low productivity is immensely hit. While all the existing species in drylands, including humans, are coping with extreme climate variations for millennia, future climate change predictions put dryland agriculture in a threat zone. Drylands support 38% of the world’s population; therefore, climate change coupled with population growth and global food security draws the attention of …

Exploring The Evolution Of Trypanosoma Cruzi And The Emergence Of Chagas Disease In The Context Of Environmental Change: Applying The Stockholm Paradigm To Archaeoparasitology, Part I, Aida Romera Barbera, Daniel R. Brooks, T. Michael Fink, Karl J. Reinhard

Karl Reinhard Publications

The Stockholm Paradigm is an evolutionary synthesis that explains the emergence of novel pathogens in the context of environmental disturbances. Considering the urgent climate change situation, anticipation stands as key to prevent and mitigate the effects that climate change can have in the emergence of pathogens. However, the success of preventive measures is hindered by a limited knowledge of the interplaying dynamics between biology, environment, and culture leading to emerging infectious diseases. For many decades, bioarchaeologists have been gathering data on past human-environment interactions, therefore contributing to the conversation. Archaeoparasitology, at the intersection between pathology, bioarchaeology, and biology, is uniquely …
