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 …

Development Of Enzyme-Based Biotechnology For Removing Stickies And Regaining Fiber Quality In Paper Recycling, Yun Wang
Dissertations
Producing paper with recycled paper consumes about 30-70% less energy and emits less GHG than using virgin wood. However, with current recycling practices, more foreign matters are commingled with the recycled paper including hot-melt adhesives, food residues, inks, resins/sizing agents, and coating adhesives, which result in stickies issues in the paper remanufacturing process. On the other hand, recycled fibers inherently have lower quality due to mechanical treatment, heating, chemical processing, and aging in various types of application/use of paper products, limiting the production of high-quality paper grades from recycled fibers. The goal of this dissertation research is to address both …
New Alternative Methods Developed For The Measurement Of Active And Total Clay In Foundry Green Sands, Piao Jian Tan
New Alternative Methods Developed For The Measurement Of Active And Total Clay In Foundry Green Sands, Piao Jian Tan
Dissertations
Precise measurement of active clay content in molding sand is essential in the metal casting foundry to produce high quality end products with no defects. The historical methylene blue (MB) test was considered qualitative, subjective and prone to operator bias in regard to the reading of the halo. A new spectrophotometric or digital clay technique has been developed. The test utilizes the cation exchange capabilities of the Cu(II)-triethylenetetramine dye and the absorbance reading of the sequestered solution through a UV-Vis spectrophotometer. Working with multiple laboratories (Decher, MTI, EJ, and JD) on actual foundry green sand samples, the method was optimized …

Turkish Journal of Agriculture and Forestry
Soil is the main influencing factor for plant growth, reproduction, and distribution. With the acceleration of industrialization and the intensification of human activities, the problem of heavy metal pollution in agricultural soil is becoming increasingly prominent. Heavy metals in soil are toxic and easily absorbed by plants, and consuming contaminated crops poses a great threat to human health. Therefore, it is necessary to monitor the content of heavy metals (HMs for short here) in soil. Hyperspectral Remote Sensing (HRS for short here) has great application prospects in obtaining quantitative information of soil organic matter, minerals and other components due to …

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 …

Influences Of Sex, Morph, And Weather On Roosting Distributions In Overwintering White-Throated Sparrows (_Zonotrichia Albicollis_), Rebecca Stephens
Honors Theses
Habitat choice influences survival by affecting access to resources, shelter from predators, mating opportunities, and numerous other costs and benefits. As such, habitat conservation is crucial, especially for migratory songbirds which are declining primarily due to habitat destruction. White-throated Sparrows (Zonotrichia albicollis) are a well-studied migratory songbird, but little is known about their roosting behaviors or how those behaviors are affected by sex, color morph, or weather. To determine this, we tracked White-throated Sparrows to their roosts, determined core home ranges, and analyzed the average distances of roost sites to the home range centroids according to these factors. …

Attia, Asmaa M. Abushady, Itoh Kimiko, Muhammad Ramzan Khan, Ghulam Muhammad Ali
Turkish Journal of Agriculture and Forestry
As an important macro element for all living cells, phosphorus is essential in agricultural production systems as well and is required in large quantities by elite varieties of crops to maintain yields. Approximately 70% of worldwide cultivated land suffers from phosphorous deficiency, and it has recently been estimated that worldwide phosphorous resources will be shattered by the end of this century thus increasing the demand for crops to be more efficient in their P usage. A greater understanding of how plants can maintain yield with lower phosphorous availability is highly desirable to both breeders and farmers, therefore, significant to develop …

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 …
An Ecological Analysis Of The Elevational Gradient Effect On Mushroom Community Diversity Near Andasibe, Madagascar, Zoe Garver
Independent Study Project (ISP) Collection
The effect of elevational gradients on biodiversity has been widely studied in the field of ecology (Rahbek, 1995). The evidence supports a trend for highest biodiversity at mid latitudes and decreasing biodiversity as elevation increases (Rahbek, 1997; Grytnes, 2003; Hariharan and Buckley, 2022). This effect has primarily been explained by variation of temperatures and resource availability at different elevations. However, the effect that elevation plays on fungal communities is relatively underrepresented in the literature (Dahlberg, 2001). This study analyzes changes in mushroom diversity across an elevational gradient in Mitsinjo Reserve and Analamazaotra National Park found in Madagascar. Using the Braun-Blanquet …
Assessing The Progress And Effects Of Exotic Plant Invasions In A Sustainably Used Littoral Forest Fragment In Southeastern Madagascar, Grant Gerhardt
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 …
Variations In Salinity And Forest Structure Between Marginal And Cloistered Mangrove Forests In Boca Del Drago, Bocas Del Toro, Panama, Mary Elizabeth Hodge
Variations In Salinity And Forest Structure Between Marginal And Cloistered Mangrove Forests In Boca Del Drago, Bocas Del Toro, Panama, Mary Elizabeth Hodge
Independent Study Project (ISP) Collection
Mangroves are incredibly important ecosystems that have an outsized impact on their surroundings, providing crucial ecosystem services like carbon sequestration and coastal protection. At the same time, mangroves are some of the most threatened habitats due to their valuable position along tropical coastlines. Globally, mangrove forests are deforested and degraded by aquaculture, tourism developments, urbanization, and overharvesting. Due to high rates of mangrove loss, mangrove deforestation is now illegal in Panama, though this legislation is inconsistent and allows for exceptions, especially in tourism developments. This study aims to probe the impacts of localized coastal developments on a small mangrove forest …

Independent Study Project (ISP) Collection
Forest fragmentation and increasing agricultural land use are posing threats to the diversity of vertebrates in Panama and across the Mesoamerican Biological Corridor. Protected areas are crucial for providing connectivity and maintaining vertebrate populations. For endemic species with small native ranges, these protected areas are critical for their survival due to sensitivity of habitat change. Higher species diversity and occupancy has been reported for both birds and mammals in protected and forested areas. This pilot survey of vertebrate species was conducted to determine which species live in a primary forest within the buffer zone of La Amistad International Park near …
Changing The Culture Of Ecology From The Ground Up, Elsa Abs, Moira Hough
Changing The Culture Of Ecology From The Ground Up, Elsa Abs, Moira Hough
Michigan Tech Publications
We are two early career soil ecologists in academia who entered the field of soil ecology with the goal of studying soil-climate feedbacks to make meaningful contributions to climate change mitigation. Although our training and research extensively focused on the effects of climate change on soil ecosystems, we were not trained during our PhD nor incentivized as postdocs to work on solutions for climate change mitigation. So the question we ask here is: Given the consensus among ecologists about the urgency of the climate crisis, why is our field not promoting more solutions-oriented research in training and practice? In this …

A Rare Plant In Peril: Conservation Concerns For An Endemic Alpine Plant, Ipomopsis Spicata Ssp Tridactyla, Kainoa Bolinder, Loreen Allphin, Madison Huie, Steven Flinders
Library/Life Sciences Undergraduate Poster Competition 2024
Ipomopsis spicata ssp. tridactyla, (I. tridactyla or IPTR; Fig. 2 & 12), is a rare alpine plant species endemic to the Tushar Mountains and Markagunt Plateau of southern Utah. There is limited knowledge available about population dynamics and community composition. Due to difficult abiotic conditions, alpine environments are more vulnerable to lasting damage from disturbance (Scherrer & Pickering, 2005). Ipomopsis tridactyla is listed as high-priority for conservation (Alexander, 2016). As conservation concerns for alpine plant communities increase due to climate change (Kopp & Cleland, 2013), so does the need for long-term monitoring of plant populations. Thus, we set …

Responses Of Vascular Plant Fine Roots And Associated Microbial Communities To Whole-Ecosystem Warming And Elevated Co2 In Northern Peatlands, Katherine Duchesneau, Camille E. Defrenne, Caitlin Petro, Avni Malhotra, Jessica A.M. Moore, Joanne Childs, Paul J. Hanson, Colleen M. Iversen, Joel E. Kostka
Michigan Tech Publications
Warming and elevated CO2 (eCO2) are expected to facilitate vascular plant encroachment in peatlands. The rhizosphere, where microbial activity is fueled by root turnover and exudates, plays a crucial role in biogeochemical cycling, and will likely at least partially dictate the response of the belowground carbon cycle to climate changes. We leveraged the Spruce and Peatland Responses Under Changing Environments (SPRUCE) experiment, to explore the effects of a whole-ecosystem warming gradient (+0°C to 9°C) and eCO2 on vascular plant fine roots and their associated microbes. We combined trait-based approaches with the profiling of fungal and prokaryote communities in plant roots …
