Socioecological Assessment Of Birds In Ngezi-Vumawimbi Nature Forest Reserve, Eli Taub Apr 2024

Socioecological Assessment Of Birds In Ngezi-Vumawimbi Nature Forest Reserve, Eli Taub

Independent Study Project (ISP) Collection

Effective management of natural resources requires consideration of the environment through both a physical and a sociological lens. In this study, the birds in Ngezi-Vumawimbi Nature Forest Reserve were examined through both a biological mist-net survey and a socioecological series of interviews with people living in the surrounding villages. The mist-net survey compared the understory species in undisturbed and disturbed area of the forest, as well as analyzing birds caught for biologically meaningful information on subspecies and sexual dimorphism. While the mist-net survey was largely unsuccessful, highlighting the need for alternative bird capture methods in Ngezi, it found a decrease …

Independent Study Project (ISP) Collection

The Ecuadorian white-fronted capuchin, Cebus albifrons aequatorialis, is a critically endangered primate species native to Ecuador and northern Peru. Their population consists of only a handful of surviving troops spread out across this region. One surviving population exists in La Hesperia Cloud Forest Reserve in Ecuador. This reserve serves as an education and volunteer site for dozens of international travelers every year. I studied the effect of the presence of humans and the lodging they have constructed. Specifically, I investigated the effect on behavior of the proximity of the troops alpha male to manmade structures in the reserve. I …


A Connected-Component Improvement Procedure For Relative Isolation Probability Calculation, Renzo Roel P. Tan, Kazushi Ikeda Apr 2024

A Connected-Component Improvement Procedure For Relative Isolation Probability Calculation, Renzo Roel P. Tan, Kazushi Ikeda

Quantitative Methods and Information Technology Faculty Publications

Due to the prevalence of natural disasters, the resilience of networks that provide essential services to the population has been studied. A recent contribution is the probability of relative isolation, which measures the likelihood of a demand node to be unreachable by supply nodes. The existing procedure for calculation is an enumerative decision-diagram-based approach that may be resource-intensive especially on occasions when time and memory constraints are imposed. In response, the study reverse-engineers the current method towards increased efficiency. The proposed solution hinges on the breadth-first search, producing connected components based on the sources. The algorithm is then benchmarked on …


Paradox Lost: Wide Gape In The Ordovician Brachiopod Rafinesquina Explains How Unattached Filter-Feeding Strophomenoids Thrived On Muddy Substrates, Benjamin F. Dattilo, Rebecca L. Freeman, Kyle Hartshorn, David Peterman, Aaron Morse, David L. Meyer, Lindsay G. Dougan, James W. Hagadorn Apr 2024

Paradox Lost: Wide Gape In The Ordovician Brachiopod Rafinesquina Explains How Unattached Filter-Feeding Strophomenoids Thrived On Muddy Substrates, Benjamin F. Dattilo, Rebecca L. Freeman, Kyle Hartshorn, David Peterman, Aaron Morse, David L. Meyer, Lindsay G. Dougan, James W. Hagadorn

Earth and Environmental Sciences Faculty Publications

Strophomenoid brachiopods had thin, concavo-convex shells, were ubiquitous colonizers of Palaeozoic muddy seafloors, and are hypothesized to have filter-fed in a concave-upward orientation. This orientation would elevate their line of commissure out of potentially lethal lophophore-clogging mud. The paradox is that epi- biont distributions on strophomenoids support a convex-upward life position, as do studies of strophome- noid stability and trace fossils formed by strophomenoid sediment-clearing. A premise of the concave-upward orientation hypothesis is a narrow gape, which causes narrow, high velocity inhalant currents, leaving strophomenoids vul- nerable to sediment entrainment. Herein we investigate the gape angle of Rafinesquina using serial …


Joint Environmental And Social Benefits From Diversified Agriculture, Laura Vang Rasmussen, Ingo Grass Apr 2024

Joint Environmental And Social Benefits From Diversified Agriculture, Laura Vang Rasmussen, Ingo Grass

Earth and Environmental Sciences Faculty Publications

Agricultural simplification continues to expand at the expense of more diverse forms of agriculture. This simplification, for example, in the form of intensively managed monocultures, poses a risk to keeping the world within safe and just Earth system boundaries. Here, we estimated how agricultural diversification simultaneously affects social and environmental outcomes. Drawing from 24 studies in 11 countries across 2655 farms, we show how five diversification strategies focusing on livestock, crops, soils, noncrop plantings, and water conservation benefit social (e.g., human well-being, yields, and food security) and environmental (e.g., biodiversity, ecosystem services, and reduced environmental externalities) outcomes. We found that …


What Soil Is Worth: A Cost-Benefit Framework Analysis Of Syntropic Farming, Aubrey Kettley Apr 2024

What Soil Is Worth: A Cost-Benefit Framework Analysis Of Syntropic Farming, Aubrey Kettley

Independent Study Project (ISP) Collection

Syntropic farming, a type of regenerative agriculture, models its farming system after a forest. This type of farming prioritizes soil health while also providing a varied yield of crops. Because it is a fairly new system globally, little research has been done on the economic impacts of syntropic farming, and therefore the feasibility of scaling up regenerative systems like this. This study aims to analyze the economic feasibility of this system through a literature review and a cost-benefit analysis framework. The results highlight the applicability, environmental advantage and economic feasibility of the system. Based on the presented framework, the short …


Short-Term Larval Surveys Reveal Rainy Season Breeding Site Preferences Of Malaria Vector Anopheles Spp. In Zanzibar City, Kaeden K. Hill Apr 2024

Short-Term Larval Surveys Reveal Rainy Season Breeding Site Preferences Of Malaria Vector Anopheles Spp. In Zanzibar City, Kaeden K. Hill

Independent Study Project (ISP) Collection

Malaria is a serious illness that causes over 500,000 deaths annually worldwide, with Tanzania alone contributing to approximately 4% of those deaths. Malaria is caused by Plasmodium spp. parasites, and it is vectored by mosquitoes in the Anopheles genus. In Zanzibar City, the incidence of malaria has decreased over the past few decades due to standardized treatment protocols and public health interventions targeting adult mosquitoes. However, the incidence remains between 1-2%, with an increasing trend observed over the past few years likely stemming from continued exchange of Plasmodium spp. from other malaria-endemic areas. Because larvicidal strategies can be useful in …

Avian Diversity And Abundance Among Agricultural Land, Forested Land, And Their Ecotone In Guadalupe, Cerro Punta, Chiriquí Province, Republic Of Panamá., Stella Rae Kinard

Independent Study Project (ISP) Collection

As the human population increases, finding the balance between modifying land use for resources and protecting areas to preserve species that are threatened by anthropogenic disturbance is an ever growing problem. Guadalupe is a town in the Western Highlands of Panamá that struggles in this balance as its primary income source is agriculture, but it is located on the border of two protected areas, Parque Nacional La Amistad and Parque Nacional Volcán Barú. By understanding the unique ways in which avifauna utilize distinct vegetative landscapes, recommendations can be made for management styles of farms in Guadalupe to implement practices that …


Community Opinions On Environmental Action On Isla Porvenir And Whichub Walla In The Guna Yala Comarca, Sofia Houts Apr 2024

Community Opinions On Environmental Action On Isla Porvenir And Whichub Walla In The Guna Yala Comarca, Sofia Houts

Independent Study Project (ISP) Collection

The Guna Yala Comarca is the autonomous, self-governed territory of the Guna people, one of seven Indigenous groups in Panama. The Comarca is located on Panama’s eastern Caribbean coast and includes 365 coral islands. Forty nine Guna communities and roughly 32,000 individuals live in the territory. The Guna General Congress is the highest authority, and each community has a local congress. As a low-lying coastal region, Guna Yala is especially vulnerable to climate change and is already impacted by sea level rise, biodiversity loss, and changing precipitation patterns. Sub-national, national, and international forms of governance and environmental action are crucial …


Community Knowledge Of Shark Ecology, Abundance, And Species Composition In Wichubwala, Nalunega, And Porvenir Communities In The Guna Yala Comarca, Panamá, Kayley Jane Porter Apr 2024

Community Knowledge Of Shark Ecology, Abundance, And Species Composition In Wichubwala, Nalunega, And Porvenir Communities In The Guna Yala Comarca, Panamá, Kayley Jane Porter

Independent Study Project (ISP) Collection

Sharks play a critical role in marine ecosystems as apex predators that exert top-down control of lower trophic levels. In recent decades, global shark populations have declined to unprecedented levels, triggering a cascade effect that threatens ecosystem functioning and, therefore, coastal community livelihoods that rely on marine resources for food and income. It is known that shark populations are vulnerable and on the decline due to anthropogenic stressors such as fishing and coastal development, but shark species composition and abundance are difficult to monitor due to the evasive nature of sharks, the often remote and inaccessible location of certain shark …


Vascular Epiphyte Population Dynamics Within Human-Modified Landscapes Of Guadalupe, Cerro Punta, Chiriquí, Panamá, Lucine Tashjian Apr 2024

Vascular Epiphyte Population Dynamics Within Human-Modified Landscapes Of Guadalupe, Cerro Punta, Chiriquí, Panamá, Lucine Tashjian

Independent Study Project (ISP) Collection

Epiphytes are plants that grow on other plants non-parasitically, and globally, epiphytes compose a very large and diverse group. They are especially abundant and species-rich in the tropics- particularly, in tropical montane forest ecosystems. Human population growth in the tropics, however, has resulted in significant declines in forest cover with land being converted largely for agricultural purposes. Studies on epiphytes have traditionally been undertaken in pristine, undisturbed forest ecosystems, yet terrestrial land conversion has increased the need to understand the value of human-modified ecosystems for epiphytic populations and biodiversity conservation. This study sought to understand the relationship between human modification …

Additionally, this study particularly focuses on the opinions of actors in Vestmannaeyjar, an island community of 4,300 with an especially vibrant, significant, …


The Role Of Geomorphological Context In Vegetative Succession Within The Breiðamerkurjökull Glacial Foreland, Lucas Nerbonne Apr 2024

The Role Of Geomorphological Context In Vegetative Succession Within The Breiðamerkurjökull Glacial Foreland, Lucas Nerbonne

Independent Study Project (ISP) Collection

As glaciers retreat worldwide at an accelerating pace, understanding primary succession in these newly exposed landscapes becomes increasingly critical. This study examines the initial vegetative colonization patterns in glacial forelands, focusing on the influence of geomorphological formations of resulting plant communities. By analyzing vegetative communities in glaciofluvial and push moraine deposits, this study highlights how the more varied, channelized morphologies of fluvial deposits create potential microclimates better conducive to heterogenous plant colonization than the homogenous terrain of the nearby push moraine. Vegetative coverage, sediment size, and species abundance was collected at 480 sites across 6 different historical glacial extents across …


Demographic Consequences Of Off-River Nesting For Piping Plover (Charadrius Melodus) And Interior Least Tern (Sternula Antillarum Athalassos) In The Lower Platte River System, Nebraska, Elsa M. Forsberg Apr 2024

Demographic Consequences Of Off-River Nesting For Piping Plover (Charadrius Melodus) And Interior Least Tern (Sternula Antillarum Athalassos) In The Lower Platte River System, Nebraska, Elsa M. Forsberg

School of Natural Resources: Dissertations, Theses, and Student Research

Piping plovers (Charadrius melodus; hereafter, plovers) and interior least terns (Sternula antillarum athalassos; hereafter, terns) are two avian species that nest along the Lower Platte River system (LPRS) in Nebraska. In the LPRS, river sandbars provide natural nesting habitat, but off-river sites provide substantial nesting habitat especially when sandbar habitat is scarce. Although presumed to be important for the persistence of plovers and terns, off-river habitat is not self-sustaining and predicted to decline. Understanding the vital rates of plovers and terns in the LPRS will inform the role of off- river sites in the future conservation …


The Effect Of Sample Grinding On Color-Based Predictions Of Soil Organic Carbon, Mason Rutgers Apr 2024

The Effect Of Sample Grinding On Color-Based Predictions Of Soil Organic Carbon, Mason Rutgers

Honors Program: Senior Projects (Public)

Measurements of soil color are widely accessible and can be used as indirect measures of soil organic carbon (SOC). Sensor-based soil color measurements, frequently used in quantitative studies to predict SOC, often use ground and sieved soil samples for color analysis. However, it is unknown whether the extra steps of drying, crushing, and sieving a sample improve the quantitative relationship between color and SOC. This study was conducted to evaluate color-based predictions of SOC using intact, sieved (<2 mm), and fine-ground soil samples from northwest Oklahoma. Moist soil color was measured using Munsell color charts (MCCs) and a Nix Mini 3™ portable color sensor (PCS). The color of the soil samples was measured before processing, after crushing to pass through a 2-mm sieve, and after mechanical grinding to less than 0.25-mm. Using Munsell value (from the MCC) and CIEL* (from the PCS) as predictor variables, regression analyses were conducted to develop SOC predictive functions for each physical state. The resulting coefficients of determination (R2) and root mean squared errors (RMSE) were used to assess model fits for predicting SOC. Model contrasts were calculated to evaluate significant differences between each predictive model. All models exhibited strong relationships (0.56 < R2 < 0.70, 0.20 < RMSE < 0.25) between soil lightness and predicted SOC. Models built using aggregated samples measured with both MCCs (R2= 0.70, RMSE= 0.20) and the PCS (R2= 0.69, RMSE= 0.21) produced the best results. Models built using intact samples measured using the PCS did perform significantly better on samples dark in color (CIEL* < 30). These results suggest that grinding soil samples does not improve color-based predictions of SOC using MCCs and the PCS.


Rewilding The ”Wild West”: Restoring Bison Populations In The American Prairie, Ana Christina Diaz Apr 2024

Rewilding The ”Wild West”: Restoring Bison Populations In The American Prairie, Ana Christina Diaz

Posters - 2024

Historically, North America was home to a biodiverse and environmentally rich land, from beavers, mountain lions, numerous bird and insect species, and North America’s largest land mammal, the bison (Figure 1). The American bison (Bison bison), also referred to as buffalo, are a keystone species in their environments, meaning their absence can have detrimental effects on other species. Bison are environmental engineers that create a “mosaic of habitats” with their behaviors including wallowing, grazing, and defecating (American Prairie Foundation 2024). Bison once roamed from Canada to Mexico with a population estimated around 50 million but were tragically almost wiped to …

Non-Native Rhizophora Mangle As Sinks For Coastal Contamination On Moloka’I, Hawai’I, Geoffrey Szafranski, Elise F. Granek, Michelle L. Hladik, Mia Hackett

Environmental Science and Management Faculty Publications and Presentations

Coastal mangrove forests provide a suite of environmental services, including sequestration of anthropogenic contamination. Yet, research lags on the environmental fate and potential human health risks of mangrove-sequestered contaminants in the context of mangrove removal for development and range shifts due to climate change. To address this, we conducted a study on Moloka'i, Hawai'i, comparing microplastic and pesticide contamination in coastal compartments both at areas modified by non-native red mangroves (Rhizophora mangle) and unmodified, open coastline. Sediment, porewater, and mangrove plant tissues were collected to quantify microplastic and pesticide concentrations across ecosystem type. Average microplastics were similar between …


Assessing The Impact Of Climate Change On Harbor Seals: Haul-Out Patterns In Iceland Using Cmip6 Projections, Colin Lau Apr 2024

Assessing The Impact Of Climate Change On Harbor Seals: Haul-Out Patterns In Iceland Using Cmip6 Projections, Colin Lau

Independent Study Project (ISP) Collection

Harbor seals (Phoca vitulina) are known to exhibit a preference for specific environmental and weather conditions when hauling out, particularly during the pupping and molting cycles during summer. Climate change is projected to have a significant impact on the haul-out patterns and site conditions of harbor seals in Iceland, which could further diminish their dwindling population. A comprehensive literature review was conducted to identify and discuss the environmental variables that can affect haul-out probability. Among them, surface wind speed and air temperature are reported to have the biggest influence on harbor seal haul-out numbers between May and August. Climate projections …


Assessing The Progress And Effects Of Exotic Plant Invasions In A Sustainably Used Littoral Forest Fragment In Southeastern Madagascar, Grant Gerhardt Apr 2024

Assessing The Progress And Effects Of Exotic Plant Invasions In A Sustainably Used Littoral Forest Fragment In Southeastern Madagascar, Grant Gerhardt

Independent Study Project (ISP) Collection

While it is important to conserve Madagascar’s unique natural forest environments and the biodiversity they contain, it is also essential that populations reliant on these ecosystems for their income and survival have access to the resources they provide. Sustainable use forests, designated by the IUCN as category VI protected areas, are the solution to meeting both of these conditions. At the same time, it is often the case that the use of forests invites disturbance, which in turn encourages the introduction and establishment of nonnative or invasive plant species. This study examines the degree to which the intensity of use …

Mushroom Composition Across An Elevational Gradient During The 2024 Wet Season In Mazumbai Forest Reserve, Tanzania, Christopher Brady

Independent Study Project (ISP) Collection

Mushrooms are key bioindicators that contribute greatly to ecological health, and their diversity is indicative of a healthy ecosystem. However, even with the vital role they play in ecological health, there are few studies which measure the diversity of mushrooms in Mazumbai Forest Reserve (MFR), Tanzania, Africa, and none which focus on diversity along the elevational gradient within the reserve (1300-1900m). This study measures the diversity and equitability of mushrooms growing in six elevational zones within MFR during the rainy season of 2024. A species checklist of mushrooms growing in MFR during the 2024 rainy season was created, tracking the …


Assessing The Impacts Of Anthropogenic Activities On Coral Reef Health In Ushongo, Tanzania Using Coral Diversity And Parrotfish Abundance As Indicators, Thao Mai Apr 2024

Assessing The Impacts Of Anthropogenic Activities On Coral Reef Health In Ushongo, Tanzania Using Coral Diversity And Parrotfish Abundance As Indicators, Thao Mai

Independent Study Project (ISP) Collection

Coral reefs, covering two-thirds of our oceans, are vital and diverse ecosystems, earning them the nickname of “rainforests of the sea”. Despite occupying only 1% of the ocean’s floor, they support 25% of all marine species, providing shelter, nursery ground and food, all the while also protecting the coast and providing job opportunities for local communities. Considered keystone species, coral reefs are highly sensitive to disturbances caused by pollution, climate change, but also anthropogenic activities such as coastal development, destructive fishing practices and tourism, endangering their existence and the entire marine ecosystem. Parrotfish, a crucial resident of these ecosystems, often …


Early Report Of A Microcosm Of The Fourth Major Global Bleaching Event: A Comprehensive Survey Of Coral Bleaching At Chumbe Island Coral Park, Zanzibar, Christian Boudreaux Apr 2024

Early Report Of A Microcosm Of The Fourth Major Global Bleaching Event: A Comprehensive Survey Of Coral Bleaching At Chumbe Island Coral Park, Zanzibar, Christian Boudreaux

Independent Study Project (ISP) Collection

Coral reefs harbor a wealth of the biodiversity present in the ocean. They provide an array of ecological and economic services that make them crucial to the function of a healthy ocean and prosperous coastal communities. Due to an array of anthropogenic stressors, including an increase in ocean temperatures as a result of climate change, reefs have been devastated worldwide. This is, in large part, due to the process of coral bleaching, the expelling of symbiont algae which the coral needs to produce energy, for an extended period until death. This study surveyed bleaching and death at a deeper and …

Sovereign Seeds: Analyzing The Sustainability Of Peasant Seeds In The Context Of Climate Change And Rural Exodus In Tunisia, Alice Carlson Apr 2024

Sovereign Seeds: Analyzing The Sustainability Of Peasant Seeds In The Context Of Climate Change And Rural Exodus In Tunisia, Alice Carlson

Independent Study Project (ISP) Collection

How sustainable are peasant seeds? I answer this question on the basis of three elements: environment, economy, and social justice. Using interviews with farmers from various regions of Tunisia, an interview with an expert on climate change and migration, and an interview with a civil society organization working to promote sustainable agriculture, I found that peasant seeds are a sustainable solution for a suffering agricultural sector. Depleted water sources and drought are bringing to light the problems with water-intensive hybrid seeds, and farmers are losing money. As young men increasingly leave the agricultural sector, women are left behind, finding themselves …

Independent Study Project (ISP) Collection

As a globally recognized hotspot of biodiversity, the Ecuadorian Chocó Andino region is extremely important for research and conservation. However, little research has been done regarding the mutualistic networks that sustain this ecosystem. The analysis of plant-pollinator networks helps us understand how ecosystems respond to change and is vital to conserving ecological productivity across multiple spatial scales. This study establishes a baseline for pollinator network structure across a land use gradient near the western montane cloud forest in Ecuador. Plants and pollinators were sampled along 11 transects in farms, communities, roads in the Río Manduriacu valley. Weedy herbs dominated overall, …


Impacts Of Gas Flaring On Soil Quality In The Ecuadorian Amazon: Measuring Gas Flare Effects On Soils At Comparative Distances In Loma Del Tigre, Orellana, Francesca Lopresti Apr 2024

Impacts Of Gas Flaring On Soil Quality In The Ecuadorian Amazon: Measuring Gas Flare Effects On Soils At Comparative Distances In Loma Del Tigre, Orellana, Francesca Lopresti

Independent Study Project (ISP) Collection

Gas flaring, the process of burning off the natural gas excreted during petroleum extraction, has recently been the source of public outcry, citing degraded public and environmental health caused by constant flaring near populated centers. While extensive research has been done on the environmental and health impacts of gas flaring, regionally specific research to the Ecuadorian Amazon is lacking. It is crucial that updated research in this region is produced to inform regulations that have the potential to minimize the physical, environmental, and economic impact of the petroleum industry on nearby, under-resourced, and marginalized communities. While air quality surrounding gas …
