Relationship Between Trunk Cross-Sectional Area Growth And Water Stress In Garry Oaks (Q. Garryana): A Species Of Conservation Concern, John Cochrane

Student Research Symposium

In the Pacific Northwest, Quercus garryana (Garry oak trees) support over 627 native species. Garry oak natural habitat was originally maintained by indigenous practices but has been reduced to 5-10% of its range due to change in land management strategies. To support oak conservation, we need to understand heat and water affect the growth and physiology of this species. In this study, we created a fixed linear model of trunk cross-sectional growth with water stress (Ψ), photosynthetic water-use efficiency (δ¹³C), and leaf Carbon-Nitrogen ratio. We collected branch samples from the canopies of 47-64 mature Garry oaks in the …

Summer 2024 Research Proposal: Swanberg Sanctuary Prairie Plant Community Characterization And Management Testing, Jillian Becksfort

Scholar Week 2016 - present

Prairie management is an involved process that is focused on maintaining existing grassland plant and animal communities. Invasive species and the spread of woody shrubs and trees presents a real threat to the existing prairie. Woody stems can affect resources such as water access and nutrient availability, which may cause changes to the prairie’s unique plant communities. Management techniques like burning and mowing are commonly used to prevent woody stems from causing changes to the prairie ecosystem. The Sanctuary was restored to natural prairie habitat in 2008 and a list of planted species is available. However, no plant surveys have …

Checking For Ticks: Analyzing The Efficiency Of Different Tick Collection Methods, Peter Briggs, Lawson Trimmell, Javier Monzón

Seaver College Research And Scholarly Achievement Symposium

Ticks are the most important arthropod disease vectors in both North America and Europe. Field collection of wild ticks is vital for research on the ecology of vector-borne diseases. Dragging and trapping are the two most common methods for collecting wild ticks. Dragging involves a researcher pulling a canvas through a field to collect ticks searching for a host, while trapping exploits ticks’ natural attraction to carbon dioxide to lure them onto a canvas where they get caught on tape. Our study aimed to evaluate which of these two methods is more effective. We chose six sites across three states, …

Evolution In Segregating Genotype Mixtures Of Subterranean Clover, P.G. H. Nichols, P S. Cocks

IGC Proceedings (1997-2023)

A complex segregating mixture of subterranean clover (Trifolium subterraneum L.), was sown in 1978 at Nabawa and Mt Barker, two contrasting sites in Western Australia. Seed harvested from both sites from 1980-1994 was grown out at Shenton Park in 1995, along with seed of the original mixture. Populations diverged markedly for mean days to first flowering (DFF) within three seasons. No further trends in mean DFF occurred in plants derived from the next 14 years, although standard deviation declined significantly in plants from Mt Barker. Between season differences in mean DFF were correlated with estimated growing season length at …

Role Of The Grassland Society Of Bosnia And Herzegovina In Grassland Agriculture, S. Alibegovic-Gbic, M. Bezdrob

IGC Proceedings (1997-2023)

The biggest part of Bosnia and Herzegovina is covered with hilly and mountainous terrain, which, from the agricultural perspective, determines the manner of soil usage. Of all agricultural areas in Bosnia and Herzegovina, 55.49% are covered by grassland with that figure increasing to 79.14% in mountainous regions. Therefore, grassland agriculture and its cousin livestock production are the most significant part of the Bosnian economy. In the current situation natural grasslands are largely neglected and give a low yield of forage of low quality. Many areas are completely abandoned and have been gradually overgrown with weeds and bushes. Yet a special …

Parasite Communities In Sunfish (Centrarchidae) From The Olentangy River, Sophia Holupka

Student Symposium

Parasites are common in freshwater fishes, and sunfish (Family Centrarchidae) in particular have been found to have diverse parasite communities in North America. We have been studying parasite communities that are found in sunfish (Family Centrarchidae) in three different localities (Delaware Run, River Run Park, and William Street Bridge) along the Olentangy River in Delaware, Ohio. The presence of multiple species of sunfish in the Delaware Run and nearby Olentangy River has given us an opportunity to compare parasites among them. A total of 212 fish were collected August 2022 through April 2023 and examined for parasites. We found a …

Deep Learning Can Be Used To Classify And Segment Plant Cell Types In Xylem Tissue, Sean Wu, Reem Al Dabagh, Fabien Scalzo, Helen Irene Holmlund

Seaver College Research And Scholarly Achievement Symposium

Studies of plant anatomical traits are essential for understanding plant physiological adaptations to stressful environments. For example, shrubs in the chaparral ecosystem of southern California have adapted various xylem anatomical traits that help them survive drought and freezing. Previous studies have shown that xylem conduits with a narrow diameter allows certain chaparral shrub species to survive temperatures as low as -12 C. Other studies have shown that increased cell wall thickness of fibers surrounding xylem vessels improves resistance to water stress-induced embolism formation. Historically, these studies on xylem anatomical traits have relied on hand measurements of cells in light micrographs, …

Interacting Effects Of Disease And Weather Variability On Rangeland Biodiversity Associated With Black-Tailed Prairie Dog (Cynomys Ludovicianus) Colonies, Courtney J. Duchardt, J. D. Hennig, D. Pellatz

IGC Proceedings (1997-2023)

Rangeland ecosystems worldwide are experiencing novel pressures during the Anthropocene, including land conversion, disease dynamics, non-native species, and climate change. These issues can be compounded in rangelands occupied by burrowing rodents. Often considered keystone species important for maintaining rangeland biodiversity, these species often experience widespread control efforts because of their potential to reduce forage for livestock. We examined the effects of climatic variation and disease on bird communities associated with a North American burrowing rodent, the black-tailed prairie dog (Cynomys ludovicianus). Following an outbreak of sylvatic plague (Yersinia pestis) in the prairie dog population, we observed …

The Effect Of Changing Substrate On Arctic Aquatic Invertebrates Abundance, Tom Dolman

Michael D. Wilson Symposium

Climate change is directly affecting tundra ecosystems in northern regions, and warming temperatures have caused discontinuous permafrost and thawing sediments across the region. This project investigates how increasing erosion and the foraging patterns of migratory snow geese may degrade habitat for aquatic invertebrates in the upper Mast River, located in Wapusk National Park, Manitoba, Canada. In the past two decades, many of the important species of aquatic invertebrates have shown declines. Declining invertebrate populations are predicted to affect aquatic ecosystems and decrease the resources available to shorebirds and waterfowl, which breed and migrate through this area.

Impact Analysis On The Invasive Oriental Weather Loach (Misgurnus Anguillicaudatus) In The Grant Creek And Prairie Creek Watersheds At Midewin National Tallgrass Prairie, Adam Vanhaitsma

Scholar Week 2016 - present

Presentation Location: Weber Center, Room 101

Abstract

In 2014, the invasive Oriental weather loach was found in the Prairie Creek wetland at Midewin National Tallgrass Prairie. While little is known about the Oriental weather loach and its impact on freshwater ecosystems it has become a widespread invasive species. Being the first to investigate the impact of the Oriental weather loach on the Grant Creek and Prairie Creek watersheds at Midewin National Tallgrass Prairie, we set traps for specimens from early June till late July in both watersheds. Each loach that was caught was euthanized and dissected in order to understand …
