Wildfires are increasing in risk and prevalence. The most destructive wildfires in decades in Australia occurred in 2019–2020. However, there is still a challenge in developing effective models to understand the likelihood of wildfire spread (susceptibility) and pre-fire vegetation conditions. The recent launch of NASA's ECOSTRESS presents an opportunity to monitor fire dynamics with a high resolution of 70 m by measuring ecosystem stress and drought conditions preceding wildfires. We incorporated ECOSTRESS data, vegetation indices, rainfall, and topographic data as independent variables and fire events as dependent variables into machine learning algorithms applied to the historic Australian wildfires of 2019–2020. …

Jurnal Kebijakan Ekonomi
Indonesia has the largest coral population in the world, contributed as the world’s second largest ornamental corals exporter after Japan. Coral trade sparked the issues of habitat destruction, illegal trade, and coral health problems has prompted the government to banning of ornamental coral export. This study aims to find an empirical evidence does the policies mentioned above affect the condition of coral reefs in Indonesia. The author uses the Fixed-Effect Model on the Difference in Difference regression equation whose result show that export banning of ornamental corals does not significantly affect the condition of coral reefs in Indonesia.

Identifying Invasive Species Sightings From Geoai-Validated Social Media Posts, Nathan Fox, Derek Van Berkel
I-GUIDE Forum
The spread of invasive species requires scalable monitoring techniques to help guide management and conservation strategies. Here, we explore the potential of GeoAI for the rapid validation of invasive species sightings through social media data. We utilized the Flickr API to retrieve 23,000 images from posts that contained the names of 72 invasive species across various taxonomic categories within the contiguous USA. Then using BioCLIP, a computer vision model capable of identifying over 450,000 species, we assessed whether these posts genuinely contained the species that the user tagged. Results varied, with some species like the European Starling showing high match …

Living Dead Forests: Assessing Detrital Services In Puget Sound Pseudotsuga Menziesii Ecosystems, Forrest Becker
Living Dead Forests: Assessing Detrital Services In Puget Sound Pseudotsuga Menziesii Ecosystems, Forrest Becker
Capstone Collection
Coarse woody debris (CWD), the detrital result of down wood recruitment, contributes to wildlife habitat, nutrient cycling, morphological processes like soil formation, and each forest’s sense of place but if undermanaged can fuel wildfires or obstruct stakeholder use. Despite its ubiquity in Puget Sound Douglas fir (Pseudotsuga menziesii) forests in Washington, USA, few studies quantify the exact ecosystem services which down wood provides. This study seeks to understand how forest managers can estimate the ecosystem services of down wood and how human communities perceive down wood management between community, public, and private Douglas fir (P. menziesii) …

A Decade Of Earth-Centered Scholarship And Activism, Elizabeth Allison
CIIS Faculty Publications
Origin stories reveal the myriad causes that converge to birth a new initiative. On the occasion of its tenth anniversary, this essay looks back to document the context and intellectual lineage out of which the Ecology, Spirituality, and Religion graduate program at the California Institute of Integral Studies (CIIS) emerged in 2013, and suggests some possibilities for the future of transdisciplinary education and the fields of religion and ecology (e.g. Tucker and Grim 2001), religion and nature (e.g. B. Taylor 2010), and spiritual ecology (e.g. Sponsel 2012) more broadly.
Wildlife Conservation: The Importance Of Individual Personality Traits And Sentience, Karen A. Owens, Gosia Bryja, Marc Bekoff
Wildlife Conservation: The Importance Of Individual Personality Traits And Sentience, Karen A. Owens, Gosia Bryja, Marc Bekoff
Animal Sentience
Individual differences in personality types within the same species have been studied much less than differences between species and populations. Personality differences are related to risk-taking and exploration, which in turn correlate with individuals' daily responses, decisions, and fitness. Bold and shy personality types can have different advantages and disadvantages under different social or environmental pressures. Analyzing personality differences has helped clarify how elk habituate to a well-populated area and how management strategies can be adapted to them. For wolves newly repatriated to Colorado, individual personality factors are likely to prove important for adapting to their new homes as well …
Lyme Disease In The Northeast: The Unintended Consequence Of Suburban Development, Hayden Neubert
Lyme Disease In The Northeast: The Unintended Consequence Of Suburban Development, Hayden Neubert
Student Theses 2015-Present
This paper addresses the role of suburban development in the suburbs of the Northeastern United States in increasing human Lyme disease infection. Over the past 50 years, Lyme disease has become the most common vector-borne disease in the United States. In 2021, the two states with the most Lyme disease cases were New York and New Jersey, with a collective 6,524 cases, with Connecticut still representing 541 total cases. It is not a coincidence that case numbers are concentrated in suburban areas with high forest fragmentation. Chapter 1 of this essay analyzes how human land development disrupts bioregulatory ecosystem actors …
Sub-Stage Climatic Shifts During Mis 11 Refined From Diatom Assemblage Reconstruction In The Valles Caldera, New Mexico, Savannah Cutler
Sub-Stage Climatic Shifts During Mis 11 Refined From Diatom Assemblage Reconstruction In The Valles Caldera, New Mexico, Savannah Cutler
Earth and Planetary Sciences ETDs
Diatom assemblage reconstruction from the Valles Caldera sediment core (VC-3) was utilized to infer climatic and aquatic changes during a 50-thousand-year [ka] period in the Mid-Pleistocene (435-385 ka). This 50 ka interval spans most of Marine Isotope Stage 11 (MIS 11) – one of the most prominent interglacials of the past 500 ka – and is widely considered an analog for the Holocene and future climate regimes. Nearly all records from MIS 11 are either marine or ice-core based, making VC-3 unique among lacustrine sediment records as it captures insolation variations and climatic changes during the mid-Pleistocene. Analysis of the …

Ancient Wisdom, Modern Prosperity: Harnessing Traditional Ecological Knowledge To Revitalize Australia's Economy, Environment, And Human Wellbeing, Annabelle L. Baulch
Student Theses 2015-Present
This paper explores the traditional knowledge of Australia’s Indigenous people and how it can improve Australia's environment, health, and economic prosperity to shape a more sustainable future. Indigenous Australians managed the land for thousands of years; however, being forced off the land following European colonization resulted in terrible cultural, social, and environmental disruption for Aboriginal Australians and made conservation efforts difficult. Wildfires, imported species, mining, and agriculture is steadily destroying the Australian ecosystem, contributing to climate change, species extinction, and gaps in our cultural and ancestral knowledge. Chapter One overviews Australia's environmental issues; it uses quantitative data to explore the …
Survey Of The Bolctes From Fish River Nature Preserve, Noah T. Nelson
Survey Of The Bolctes From Fish River Nature Preserve, Noah T. Nelson
Honors Theses
Boletes are a special kind of mushroom inside of the Kingdom Fungi that are distinguished from other mushrooms by their uniquely pored hymenium, as opposed to gills. Many boletes are ectomycorrhizal, meaning they are mutualists with vascular plants, and thus beneficial to the overall health of the terrestrial ecosystem. Some are well-known for their edibility and are of economic importance. In the United States 59 genus-level clades comprising 290 operational taxonomic units have been reported. The southeastern US and Gulf Coast regions however are less researched and recorded for their mushroom ecology. In Alabama, only 56 bolete species have been …
Ecosystem Response To Increasing Hurricane Disturbance: Comparing Nutrient Cycling Dynamics Associated With Early- And Late-Successional Tree Species In A Wet Tropical Forest, Miriam Kleit
Biology Honors Projects
Puerto Rico has seen changes in the frequency and severity of disturbances in recent years as hurricanes become more frequent and more intense under climate change. In ecosystems experiencing increasing disturbances, we expect that species composition will shift as early successional trees become more common. These changes to species composition and community ecology are likely to affect terrestrial nutrient cycling both directly and indirectly, and it is still not well understood how shifting community composition may alter ecosystem functioning. To address this gap, I measured carbon (C) and nitrogen (N) variables in soils, microbial biomass, roots, leaves, and soil greenhouse …

Using Edna To Assess Impacts Of Oyster Restoration On Ecosystem Biodiversity At A Heavily Impacted Coastal Lagoon, Dominique Di Domenico, Emily Bonacchi, Elizabeth Suter
Molloy Multidisciplinary Undergraduate Research Conference
The Great South Bay (GSB), a bar-built, temperate, coastal lagoon on the south shore of Long Island, New York, USA, is a highly modified estuary due to heavy urbanization and suburbanization in the last century. GSB historically provided up to 50% of the nation’s hard clam (Mercenaria mercenaria) harvest, and is the legal home of the “Blue Point” oyster (eastern oyster; Crassostrea virginica). However, due to overexploitation as well as persistent stress from ongoing nitrogen pollution and harmful algal blooms, shellfish populations are fractions of their original abundances. Restoration efforts in GSB, driven both by community efforts …

A significant challenge in global change research is understanding how vegetation interacts with the environment to influence ecosystem gross primary productivity (GPP) through carbon assimilation. One emerging objective is to consistently predict GPP fluctuations worldwide by establishing a robust scaling relationship between GPP measured at flux towers and satellite spectral reflectance data. However, a major hurdle in achieving this goal is the discrepancy in spatial resolution between early satellite measurements and eddy flux measurements. By using a large set of growing season data covering 100 site-years in North and Central America, we explored the potential of transforming incident and reflected …

Online citizen science platforms can be crucial to the scientific and regulatory community, but inherent biases based on organism traits can influence the likelihood of a species being reported and accurately identified. We explored how traits of orb weaving spiders impact data in iNaturalist, using the invasive Jorō spider as a case study. This species is an outlier among orbweavers due to its large size and bright coloration, and was the most frequently reported species, with the most identifications and research-grade observations. It was also reported by less experienced users on average, highlighting its potential role as a gateway species …
The Effects Of Phenological Shifts On The Reproductive Success Of Common Terns (Sterna Hirundo) And Arctic Terns (Sterna Paradisaea) In The Gulf Of Maine, Jamie W. Dinella
The Effects Of Phenological Shifts On The Reproductive Success Of Common Terns (Sterna Hirundo) And Arctic Terns (Sterna Paradisaea) In The Gulf Of Maine, Jamie W. Dinella
Student Publications
Climate change is resulting in ecosystem-wide consequences, including shifts in the geographical distribution of species and the timing of biological events, or phenology. The rapidly warming Gulf of Maine hosts breeding populations of migratory common terns (Sterna hirundo) and Arctic terns (Sterna paradisaea). I used nest check data (2013-2022) and eggshell membrane stable isotope data (2022) from Petit Manan Island in the Gulf of Maine to examine the causes and consequences of variation in phenology in common and Arctic terns. I hypothesized that the timing of an individual’s breeding was impacted by their foraging behavior and that female terns that …

Student Papers, Posters & Projects
Due to the prevalence of plastic pollution in coastal ecosystems, aquatic organisms are at high risk for accumulating microplastics (MPs). Filter-feeding bivalves, such as mussels and oysters, may be exposed to, and subsequently accumulate, MPs due to the high volume of water they pass through their bodies. This study assessed the levels of MPs within Atlantic ribbed mussels (Geukensia demissa), a common filter feeder found along the United States Atlantic Coast, from 12 sites within Rehoboth Bay, Indian River Bay, and Little Assawoman Bay, collectively known as the Delaware Inland Bays. Composited mussels from each site were digested using potassium …
Ecotheology In Context: A Critical Phenomenological Study Of Graduates Of Environmentally Focused Seminary Programs In The United States Of America, Cherice Bock
Antioch University Dissertations & Theses
In recent decades, the field of ecotheology has emerged in dialogue with the context of the interconnected environmental and climate crises, particularly relating to the critique of Christianity being used to justify human and resource exploitation. A range of disciplines within the religious academy have taken up these intersecting concerns, together termed “ecologically informed theological education.” Graduate institutions training faith leaders and theological educators have created degree programs and certifications, and/or incorporated awareness of ecology, sustainability, and care for creation into their curricula. A research approach for ecotheology is described through the conceptual framework of critical ecotheology, which acknowledges ecotheology …

Natural and nature-based features have been implemented throughout New York City to provide habitat and reduce flooding, erosion, and pollution. The West Pond Living Shoreline in Jamaica Bay, NY was designed with organic breakwaters and native marsh plants, including S. alterniflora. Post-construction monitoring in 2021 found that percent coverage of S. alterniflora was lower than expected. To inform future management, we studied the effect of elevation, planting method, and shoreline energy exposure on the percent cover, average stem height, and average stem density of S. alterniflora. Elevation and plant growth data were collected within 8 one sq. meter quadrats at …

Habitat loss due to deforestation is a primary threat to global biodiversity. Clearing tropical rainforests for agriculture leads to forest fragmentation. Forest fragments contain fewer large trees and provide lower food availability for primates compared to continuous forests. Mantled howler monkeys inhabit the increasingly fragmented rainforests of Central and South America and may need to alter their activity and spatial cohesion to mitigate competition and preserve energy in fragments where there is lower quality food. We compared howler monkey activity and spatial cohesion across a small forest fragment (La Suerte Biological Research Station, LSBRS) and a large, continuous forest (La …

Recreational trails and the presence of invasive species such as Bromus inermis can both disturb grassland community composition. Trails can act as dispersal corridors for plant material, but can also be a source of trampling and compaction. Invasive grasses like Bromus inermis can easily establish in grasslands and decrease species richness by increasing competition. Understanding these effects, this study aims to understand how both the presence of recreational trails as well as the presence of Bromus inermis affect species richness and overall community composition at Two Ponds National Wildlife Refuge. Belt transect sampling took place in fall 2019 and again …
Northern Shrimp In The Gulf Of Maine And The Impacts Of Climate Change, Alicia Hober
Northern Shrimp In The Gulf Of Maine And The Impacts Of Climate Change, Alicia Hober
Honors Theses
Northern Shrimp (Pandalus borealis) populations within the Gulf of Maine collapsed in 2011 following the first year that sea surface temperature surpassed 10ºC. The population collapse resulting in a moratorium in 2014. The waters of the Gulf of Maine have been rising at a rate of 0.045ºC per year, changing predator distribution, prey distribution, as well as Northern Shrimp biological variables. There has been very little recovery to the Northern Shrimp stock despite the fishing moratorium and the answers behind the collapse and lack of recovery remains enigmatic. Therefore, this two-chapter study includes a literature review and a …
Modification Of Marine Snail Microhabitats By Canopy-Forming Algae, Eleanor Mcgrath
Modification Of Marine Snail Microhabitats By Canopy-Forming Algae, Eleanor Mcgrath
Honors Theses
Brown algae, including the canopy-forming macroalgae Fucus distichus, are declining in abundance around the world due to stressors associated with climate change. Local extinction of Fucus impacts the intertidal community through cascading effects as the ecosystem loses a dominant primary producer at the base of the food web. However, Fucus is not only a resource species; it is also an ecosystem engineer. This thesis investigates the effect of Fucus extinction on the abundance of two herbivorous marine snails, L. saxatilis and L. obtusata, with a focus on the role of Fucus as a habitat- modifier. Specifically, I explored: …
Measuring Nature’S Contributions To People Provided By Species In The Gulf Of Maine Rocky Intertidal Ecosystem, Madelyn L. Eippert
Measuring Nature’S Contributions To People Provided By Species In The Gulf Of Maine Rocky Intertidal Ecosystem, Madelyn L. Eippert
Honors Theses
Ecosystem services aim to quantify the value of nature provided to humans. However, Ecosystem services are typically measured at the level of the ecosystem as a whole and do not consider interactions between species in an ecosystem. Ultimately, the species in an ecosystem determine the services that are provided. Measuring ecosystem services at the landscape level misses the complex interactions and changing biodiversity of ecosystems. Currently, there is no accepted framework to link ecosystem services to species. In this thesis, I developed a framework to link Nature’s Contributions to People (NCP) to species. NCP includes 18 specific contributions (i.e. 18 …

We present the Urban Nature Indexes (UNI), a comprehensive tool that measures urban ecological performance under one standard framework linked to global commitments. The UNI was developed by interdisciplinary experts and evaluated by practitioners from diverse cities to capture each city’s ecological footprint from local to global scale. The UNI comprises six themes (consumption drivers, human pressures, habitat status, species status, nature’s contributions to people, and governance responses) that encompass measurable impacts on climate change, biodiversity loss, ecosystem services, pollution, consumption, water management, and equity within one comprehensive system. Cities then adapt the UNI to their context and capacity by …

Restoration Is Repairing Relationships: Bridging Indigenous And Western Sciences To Assess The Socio-Ecological Restoration Of Wild Rice (Zizania Palustris) On Keweenaw Bay Indian Community Homelands, Cassandra M. Reed-Vandam
Dissertations, Master's Theses and Master's Reports
Manoomin (wild rice, Zizania palustris) is an ecologically and culturally significant plant relative for the Keweenaw Bay Indian Community (KBIC). Historically, manoomin was present across much of the Great Lakes, however, their presence has declined since the early 1900s and, by 1990, virtually disappeared within KBIC homelands. Employing ethnography, surveys, focus groups, and conversations with Ojibwa knowledge holders, this research defined successful manoomin restoration for KBIC and developed socio-ecological attributes and indicators to assess restoration presented in the Medicine Wheel Framework for Manoomin Restoration. Surface water, sediment, and pore water samples at six different manoomin sites were analyzed to …

Exploring The Connection: Field Ecology Research And Student Wellbeing, Elizabeth Small
Graduate Research Theses & Dissertations
Field work is essential in ecological research, offering the opportunity to gather firsthand data, observe natural processes, and deepen our understanding of ecosystems. In my study on small mammal trophic niche dynamics, I investigate how small mammals—critical players in grassland food webs—adapt their diets in response to environmental disturbances. By examining the drivers of variation in trophic niche among three common small mammal species, I aim to uncover how these animals coexist despite similar dietary requirements. Understanding these dynamics is critical for informing global conservation efforts, especially as we work to reverse the biodiversity crisis and restore damaged ecosystems.However, the …
