Investigating The Mechanisms Of Freeze Tolerance In Lemna Minor, Tamara Bouchard

Honors Theses and Capstones

Freezing presents a significant abiotic stress to aquatic plants, yet little is known about the mechanisms by which species like Lemna minor (duckweed) survive subzero temperatures in nature. This study investigates whether L. minor employs freeze-avoidance or freeze-tolerance strategies and explores the potential role of its microbiome in enhancing cold resilience. Using both field-collected fronds from naturally frozen ponds and controlled freezing experiments in the lab, I assessed survival through viability staining and post-thaw survival. Results showed that L. minor can survive natural ice encasement and that prior cold acclimation significantly improves tissue survival under induced freezing. Trypan blue staining …

Size Structure Of Black Crappie And Bluegill In Northern, Eastern, Western, And Southern Minnesota, Ray Anderson

Journal of Earth and Life Science

Fish size structure is an important factor in a fishery population. Panfish such as black crappie Pomoxis nigromaculatus and bluegill Lepomis macrochirus play a major role in the health of fisheries. Five lakes from southern, northern, eastern, and western Minnesota were selected for analysis. Data were collected using standard sampling methods, including gill nets, electrofishing, and fyke nets. Length-frequency distributions were created to assess size structure in each region. Relative abundance was measured using catch per unit effort. Data analysis included a one-way ANOVA to compare Proportional Size Distribution (PSD) values and the distribution of fish sizes among regions. Chi-square …

Comparison Of Hoop Nets To Trap Nets In Sampling Panfish, Jayden R, Alsleben

Journal of Earth and Life Science

Panfish including bluegill Lepomis macrochirus and black crappie Pomoxis nigromaculatus are gamefish species of significance found in Minnesota. Hoop nets and trap nets are two types of gear that can be used to sample these fish. Fisheries managers and anglers alike are interested in the best tactics to capture panfish. The behavior of fish, including bluegill and black crappie, change throughout the sampling season and make it difficult to assume accurate representations. Trap nets have historically been adequate in sampling near shore populations, but questions surrounding the gear have allowed other options to be pursued. The objective of this study …

The Relationship Between Plant Density And Microplastic Concentration In The Water In Lake Bemidji, Mn, Arian Garcia

Journal of Earth and Life Science

Microplastics, plastic particles smaller than 5 mm, are an increasing environmental threat, particularly due to their widespread distribution and toxicity. While much research has focused on larger freshwater and marine ecosystems, the presence and impacts of microplastics in smaller inland lakes remain less understood. This study investigates the relationship between plant density and microplastic concentrations in Lake Bemidji, a smaller freshwater lake. A total of 30 water samples were collected across varying vegetation conditions, ranging from open water (0%) to 90% plant coverage. Microplastics were identified and categorized into six morphological types: fibers, fragments, films, spheres/beads, and foam. The samples …

A Sample Of Fish Communities In Beaver Ponds Of Northern Minnesota, Reed Cumberland, Rose Kuhlmann

Journal of Earth and Life Science

The North American beaver Castor canadensis is an ecosystem engineer and a keystone species to the environment. Beaver inhabit ponds and construct dams to build ponds that provide habitat for certain fish. Little information is provided on the species of fish that live in beaver ponds. The objective of this study is to sample the fish communities in beaver ponds while comparing the effectiveness of two styles of minnow traps. Twelve beaver ponds were selected in the Bemidji area to be sampled. The quantity and species caught in each style of trap were recorded to compare effectiveness of each trap …

Effects Of Round-Up On The Environment, Sandra J. Marcu

Journal of Earth and Life Science

Many people around the world have used and still currently use Roundup but are unaware of the effects it has on the environment. Roundup is a spray on application weedkiller that is widely used around the world today both residentially and commercially. It enables its user to grow a garden or a field of crops with a no-tilling approach to eliminate weeds. It is a well-known and popular choice for killing weeds that has been around since the mid 1970’s (Oca, 2017). John Franz, a Monsanto scientist discovered that glyphosate (main ingredient in Roundup) was an herbicide or weedkiller, and …

The Effectiveness Of The Minnesota Buffer Law And Its Impacts On People, Ellen P. Isakson

Journal of Earth and Life Science

In January 2015, the then-governor of Minnesota Mark Dayton announced new legislation that would require 50-foot vegetation buffers along all waterways in Minnesota; this legislation would come to be known as the Minnesota buffer law, exact requirements being “perennial vegetative buffers of up to 50 feet along lakes, rivers, and streams and buffers of 16.5 feet along ditches” (Albert, 2017; MN Board of Water and Soil Resources [MN BWSR] 4 ). A buffer in the context of vegetation and natural resource management is a strip of vegetation around a body of water “designed to intercept stormwater runoff and minimize soil …

Does Depth Affect Zebra Mussel Length In Scalp Lake?, Zanden Mellen

Journal of Earth and Life Science

Since its first sighting in 1996, zebra mussels Dreissena polymorpha have been confirmed in hundreds of Minnesota lakes. Not only were they found in lakes, but they are also found in rivers too. With lack of effective treatments to impede their spread, zebra mussels continue to colonize new areas causing ecological as well as economic harm. The objective of this study was to see if there was a relationship between a zebra mussel length and the depth, they are found using shell length (mm) and depth (cm). The comparison of zebra mussel length and depth was done by performing a …

Age Class Is Not Related To Size Or Composition Of Home Ranges Among Suburban White-Tailed Deer During Parturition, Nathan D. Pyburn

Journal of Earth and Life Science

How white-tailed deer use the landscape in an urban environment can help us understand the effects of urbanization on deer populations. White-tailed deer form observable matriarchal hierarchies in studied populations. This study examines the matriarchal structure, home range size, and home range composition of 25 collared white-tailed deer within the city limits of Bemidji, MN. The results found no significant difference between age class and home range size or composition. However, movement metrics from yearling and mature age classes were more similar than the juvenile age class females. I propose this is because social acceptance between mature females was higher …

Relationship Of Utricle And Trap Door Size On Common Bladderworts Utricularia Macrorhiza, Tegwen Romportl

Journal of Earth and Life Science

The common bladderwort Utricularia macrorhiza is a carnivorous aquatic plant that captures organisms with its bladders. This study was aimed at setting the stage for future research which might determine if U. macrorhiza could be a biological method of control for invasive species. The objective of this study was to determine the relationship between utricle and trap door sizes and to gather data on the size ranges of these two morphological features. A regression analysis was used to obtain results which showed there was enough evidence to suggest that the size of bladderwort trap doors have a significant, positive relationship …

The Influence Of Flower-Microbe Interactions On Bumble Bee Behavior And Gut Microbiome Composition, Success Chiamaka Ekemezie

Graduate Theses/Dissertations

This thesis examines how microbial interactions in floral nectar and environmental variation influence bumble bee (Bombus spp.) foraging behavior and gut microbiome composition. Pollen germination experiments and behavioral assays in the lab tested whether Metschnikowia reukaufii (yeast) and Acinetobacter nectaris (bacteria) induce pollen germination and bursting in nectar and affect bee behavior subsequently. Both microbes reduced intact pollen, but bees did not alter flower preference. Furthermore, the study also assessed how floral and bee community composition shaped gut microbiome composition across six Missouri prairies. Using amplicon-sequenced fungal ITS and bacterial 16S rRNA genes, I found that fungal microbiome composition varied …

Investigating Social Attenuation Of The Stress Response In Juvenile Northern Cottonmouths (Agkistrodon Piscivorus), Alyssa Owens

Graduate Theses/Dissertations

When social organisms encounter a stress-inducing event, the presence of a conspecific can dampen the physiological and/or behavioral response elicited by the stressor. This concept, termed ‘social buffering’, has been well documented in mammals, but there are few studies investigating this phenomenon in organisms traditionally perceived as asocial, including reptiles. However, the paradigm is shifting, and social behavior is now more widely recognized in reptiles, including snakes. In this study I tested whether juvenile Northern Cottonmouths (Agkistrodon piscivorous) experience social buffering by measuring changes in heart rate in snakes following an acute stressor with and without the presence …

A Mystery Of Microecology: Revealing The Ecological Relationship Between Allorhizobium Vitis And Missouri Native Grape Species, Hunter White

Graduate Theses/Dissertations

Crown gall disease can be very detrimental to grape and wine producers around the world by reducing vine vigor and yield. It is caused by the bacteria Allorhizobium vitis (A. Vitis) carrying a tumor inducing (Ti) plasmid. The A. vitis bacteria have been found in soil and cane tissues in vineyards around the world, and infect all cultivated grapes. However, there have been no reports of crown gall on native wild grapevines, and very little is known about the ecology of A. vitis in native ecosystems. I have sampled cambium tissues from three native wild grape species of …

Restoration Of Giant River Cane (Arundinaria Gigantea) In Southwest Missouri, Lyndsey D. Rightnowar

Graduate Theses/Dissertations

Giant river cane (Arundinaria gigantea), a native bamboo species, once dominated riparian landscapes across the southeastern United States but has declined to approximately 2% of its historic range. This study evaluated restoration techniques for giant cane in southwest Missouri by examining the influence of rhizome source (putative genotype), planting type, and restoration site on restoration success. I compared two planting types: greenhouse-to-field (G2F) transplanting, where rhizomes were first propagated in the greenhouse before planting, and field-to-field (F2F) transplanting, where rhizomes were directly transplanted from source canebrakes to restoration sites. Rhizomes were collected from four existing canebrakes in Taney …

Investigating The Relationships Between Biotic And Abiotic Factors Affecting Migratory Behavior In Westslope Cutthroat Trout Within The Pend Oreille System, Garrett M. Duncan

EWU Masters Thesis Collection

Salmonids express several different life histories from migrating to oceans and back or staying in their natal streams as a resident. Migratory individuals are a vital part of the overall success of populations due to the potential for increased genetic diversity and increased fecundity they offer over resident individuals. This research was completed in three basins including Priest River, Pack River, and Lightning Creek which are all connected to the Pend Oreille Basin and are important producers of Westslope Cutthroat Trout (Oncorhynchus clarkii lewisi). Thirty-nine sites were sampled between the three basins. Results were compared between these tributaries that have …

If You Build It: Using Ground Squirrel Risk Perception To Test Wildlife Crossing Structure Success, Sarah Sanz

All Master's Theses

Roads and traffic present many risks for wildlife, and animals must be able to accurately assess risks in their environment. Animals can often perceive the level of risk they face, and their behavioral responses can alter their fitness and potentially even whole-population dynamics. However, animals may be unable to properly measure the levels of risk near roadways because roads present novel environmental conditions and alter predators’ behavior. To mitigate some of the ecological problems created by roadways, wildlife crossing structures (WCSs) are being incorporated into transportation projects. To understand whether WCSs provide quality habitat for wildlife, we compared the levels …

Testing The Effect Of Source And Environment On Native Seed Germination To Inform Seed-Based Restoration Of Grasslands, Brandon Clark

Electronic Theses and Dissertations

Grasslands are one of the most endangered ecosystems on the planet, and they provide a variety of important ecosystem services that people rely on. Losses of grasslands can be mitigated through restoration. Seed-based restoration is a regularly used practice due to its practicality and cost-effectiveness. Planting non-local seed that may not be suitable for its destination environment can have consequences in plant establishment and subsequent restoration success. This experiment tested the response (final germination and germination rate) of seed from 11 perennial tallgrass species sourced from 3 different locations to different germination temperature conditions. Seeds from three sources of each …

Interspecific Interactions And Resource Availability As Drivers Of Species Occurrences, Edita Folfas

Biology Dissertations - Archive

Understanding what forces determine species occurrence is central to studies of community ecology. Species interact with each other and their environment, and these interactions scale up to shape global patterns of diversity. In my first chapter, I examined how predation might shape patterns of Anolis lizard species richness and abundance across landscapes on islands in the Greater Antilles. I quantified predatory bird occurrence by using thousands of observations from an online citizen science database (eBird). I then obtained estimates of anole abundance and diversity by conducting local field surveys and using mark-resight methods. While predators could negatively impact anole abundance …

Is Mortality Of A Common Shrub A Heritable Trait? An Experimental Evaluation Of Senescence Using The Coast Willow, Salix Hookeriana., Maylin A. On, Rj Polyack, Sarah Galloway, Erik Jules

Undergraduate Scholarship

In 2009, a common garden study involving Salix hookeriana (called “willows” from hereon) was initiated in which multiple clonal replicates were created and propagated for a total of 675 trees. Since 2009, numerous experiments and observations have been completed using the willows at the study site of Humboldt Bay Wildlife Refuge demonstrating that growth, phenology, and insect communities are influenced by genotype. Our study was aimed at understanding if senescence and mortality are correlated with both plant sex and genotype. In August of 2024, seven replicates from each of the ten genotypes in the experimental array were selected and the …

A Geometric Morphometrics Analysis Of The Limb Morphologies Of Mosasaurs And Its Palaeoecological Implications, Zachary J. Herbert

Master's Theses or Doctor of Nursing Practice

Mosasaurs were a major component of Late Cretaceous marine ecosystems, being the last Mesozoic radiation of secondarily aquatic tetrapods into diverse niches.

To shed light on the diversity and evolution of limb morphology in this clade, geometric morphometrics analyses were performed on seven skeletal elements from the forelimb and hindlimb. This study tested the hypothesis tested that mosasaurs living in similar environments would exhibit similar morphologies.

After analyzing datasets containing 29 taxa, the observed patterns did not support the hypothesis that habitat was the primary variable influencing morphology. The recurrence of a pattern, the plotting of plioplatecarpine mosasaurs closer to …

The Influence Of Anthropogenic Infrastructure On The Reproductive Success Of Northern House Wrens (Troglodytes Aedon) In Proximity To Highways, Nana-Esi Irie Hanson

Master's Theses or Doctor of Nursing Practice

Anthropogenic disturbances, particularly road infrastructure and noise pollution, significantly affect avian populations, influencing their ecology, behaviour, and reproductive success. This study examined the impact of highway proximity on the reproductive success of the Northern House Wrens (Troglodytes aedon) in a rural landscape. Noise levels and reproductive outcomes were compared between two sites in Hays, Kansas: a high-traffic site near Interstate 70 (Sternberg Museum Nature Trail) and a lower-traffic site at Big Creek on the Fort Hays State University campus. I hypothesized that increased traffic volume and noise pollution would negatively affect Northern House Wren reproductive success. Ambient noise …

Early Season Tropical Cyclones Affect Birds Breeding On A Barrier Island, Theodore J. Zenzal Jr., Amanda N. Anderson, Brock Geary, Jessica Schulz, Robert C. Dobbs, Wylie C. Barrow Jr., James H. Waddle

Gulf and Caribbean Research

Animal populations often experience acute natural disturbances, most of which are connected to short—term weather events. Occurrences of early—season tropical cyclones during the peak of the avian breeding season are likely to increase with climate change, which can substantially impact populations of coastal breeding birds at multiple scales. To understand the acute impacts of severe tropical cyclones, we investigated how abundances of breeding birds changed before and after 4 early season named tropical cyclones on a barrier island in the Gulf of Mexico. We detected a change in pre— versus post—storm numbers of breeding birds after 2 out of 4 …

Ina Scuba: Mobilization Of French West Indies Scuba Diving Clubs To Rapidly Improve Knowledge On Threatened Marine Species. Case Of The White-Spotted Eagle Ray (Aetobatus Narinari)., Océane Beaufort, Rocio Prieto González

Gulf and Caribbean Research

The White—Spotted Eagle Ray (Aetobatus narinari), listed as Endangered on the IUCN Red List since 2021, is experiencing alarming population declines, underscoring the urgent need for targeted conservation efforts. This species, which plays a vital ecological role in marine food webs, has biological and ecological characteristics that make it particularly vulnerable to habitat degradation and anthropogenic pressures, particularly fishing, tourism, and maritime traffic. In the French West Indies (FWI), the paucity of data on the White—Spotted Eagle Ray remains a major obstacle to the development of effective, island—specific conservation strategies. To address this gap, the INA Scuba participatory …

The future of coral reefs remains uncertain as intensifying ocean warming continues to drive coral decline and demise worldwide. Corals occurring in extreme environments such as the Persian/Arabian Gulf (PAG), the world’s warmest sea, represent a promising resource to study the genetic architecture of thermal tolerance. However, their thermal capacities remain unresolved. We applied short-term heat stress assays using the Coral Bleaching Automated Stress System (CBASS) to determine signatures of thermal tolerance from three common species (Porites harrisoni, Platygyra daedalea, and Cyphastrea microphthalma) across three sites (two in the extreme southern PAG and a more benign …

Selective Nutrient Incorporation May Underestimate Heterotrophy Of A Mixotrophic Reef-Building Coral, Connor R. Love, Marleen Stuhr, Michael D. Fox, Veronica Z. Radice, Maoz Fine, Kelton W. Mcmahon, David L. Valentine

Biological Sciences Faculty Publications

Mixotrophic reef-building corals acquire nutrition via photosynthate translocation from endosymbiotic microalgae and by heterotrophic prey/particle capture. Heterotrophy promotes resistance to, and recovery from, environmental stress, but quantifying coral heterotrophy remains difficult due to complex resource exchanges within the coral holobiont. We interrogated the response of multiple biomarkers to coral heterotrophy using fatty acid profiling and stable isotope analysis of Stylophora pistillata grown along a controlled feeding gradient from pure autotrophy to pure heterotrophy. We found that fatty acids and nitrogen were effectively incorporated into both coral host and symbiont tissues, while carbon, which is the primary target for conventional heterotrophy …
