Designing Sustainable Systems Using Nature’S Toolbox, Matthew J. Hasenjager
Designing Sustainable Systems Using Nature’S Toolbox, Matthew J. Hasenjager
Faculty Publications and Other Works -- Ecology and Evolutionary Biology
Supporting the Earth’s human population without destabilizing planetary processes is the central challenge of sustainability science. Key to achieving this goal is designing systems that are robust and resilient to dynamic and unpredictable conditions. Bioinspiration leverages naturally evolved solutions to address such challenges, yet a solution derived from one-to-one correspondence between a natural and artificial challenge can be limited in its broader application. Here we advocate for an approach to nature-inspired design that forgoes mimicking specific solutions in favor of identifying general design features that enable natural systems to function. These features are not specific to any naturally evolved solution …

Analyzing Phototaxis And Related Visual Behaviors Among Diverse Species Of Drosophila, Madeline M. Hill
Analyzing Phototaxis And Related Visual Behaviors Among Diverse Species Of Drosophila, Madeline M. Hill
Honors Theses
Phototaxis and related visual behaviors can vary between species, and thus members of the genus Drosophila make an excellent study system to examine the evolution of vision. While some existing research points to these phototactic behaviors arising due to mating requirements or due to their species-specific ecology or environmental factors, there exists a lack of understanding as to why striking behavioral differences can exist between closely related species, or between members belonging to the same genus. The present research seeks to uncover the specifics regarding these discrepancies in visual evolution and aims to provide a foundation of knowledge about visual …

Art & Sex Through the Lens of Botany seeks to impart the importance of making connections across disciplines and the value of visual literacy across academic lines. The course introduces foundational concepts in each field and encourages students to integrate and explore these different systems of knowledge and their intersections. In addition to developing fluencies related to both general botany …
Consequences Of The Megafauna Extinction: Changes In Food Web Networks On The Edwards Plateau Across The Pleistocene-Holocene Transition, Quentin A. Smith Jr.
Consequences Of The Megafauna Extinction: Changes In Food Web Networks On The Edwards Plateau Across The Pleistocene-Holocene Transition, Quentin A. Smith Jr.
School of Biological Sciences: Dissertations, Theses, and Student Research
We are experiencing biodiversity loss due to climate change and human impacts, which is not only harmful to the environment but can also alter the composition of communities and interactions among species. The late Pleistocene experienced a loss of large-bodied mammals which resulted in significant changes in community structure due to changes in body size, diet, and species associations. The impact of these changes on species interactions and community structure across the Pleistocene-Holocene transition remains poorly understood. Using a robust data set of species composition, stable isotopes, body size, and climate variables, we constructed and compared ecological networks of mammal …
An Examination Of The Eastern Nebraska And Western Iowa Flash Flood Event Of 6-7 August 1999, Catherine M. Zapotocny
An Examination Of The Eastern Nebraska And Western Iowa Flash Flood Event Of 6-7 August 1999, Catherine M. Zapotocny
NOAA Technical Reports and Related Materials
Flash flooding occurs each summer in eastern Nebraska and western Iowa. While 10-inch rains are extraordinary, it is not uncommon to have at least one excessive rain event during the annual convective season. A significant flash flood occurred in east central Nebraska and western Iowa the night of August 6, 1999 into the morning of August 7, 1999. Antecedent hydrologic conditions limited the loss of life, however considerable property damage resulted as the heavy rain fell over the urbanized areas in eastern Nebraska and western Iowa.
Several flash flood ingredients came together over the area. These meteorological factors are typical …
Rescape: Transforming Coral-Reefscape Images For Quantitative Analysis, Zachary Ferris, Eraldo Ribeiro, Tomofumi Nagata, Robert Van Woesik
Rescape: Transforming Coral-Reefscape Images For Quantitative Analysis, Zachary Ferris, Eraldo Ribeiro, Tomofumi Nagata, Robert Van Woesik
Ocean Engineering and Marine Sciences Faculty Publications
Ever since the first image of a coral reef was captured in 1885, people worldwide have been accumulating images of coral reefscapes that document the historic conditions of reefs. However, these innumerable reefscape images suffer from perspective distortion, which reduces the apparent size of distant taxa, rendering the images unusable for quantitative analysis of reef conditions. Here we solve this century-long distortion problem by developing a novel computer-vision algorithm, ReScape, which removes the perspective distortion from reefscape images by transforming them into top-down views, making them usable for quantitative analysis of reef conditions. In doing so, we demonstrate the …

Effects Of Fungal Biopesticide Doses On Mortality In Bumble Bees, Colton Burris
Effects Of Fungal Biopesticide Doses On Mortality In Bumble Bees, Colton Burris
Undergraduate Research Symposium
Agricultural practices often include the use of pesticides to produce meaningful crop yields. While the pesticide may be used to target “pest” insects (e.g. thrips, aphids, whiteflies), it can also have negative effects on important pollinating insects such as bees. Neonicotinoid pesticides have been found responsible for widespread decline in bee biodiversity, and were even banned in Europe (Sgolastra et al. 2020) . Beauveria bassiana, sold as Botanigard, on the other hand, is a fungal biopesticide that is marketed to be a safer alternative for bees, and has been found to have other possibly harmful effects to the inner …
Continuous Mowing Differentially Affects Floral Defenses In The Noxious And Invasive Weed Solanum Elaeagnifolium In Its Native Range, Alejandro Vasquez, Alexa Alaniz, Robert K. Dearth, Rupesh R. Kariyat
Continuous Mowing Differentially Affects Floral Defenses In The Noxious And Invasive Weed Solanum Elaeagnifolium In Its Native Range, Alejandro Vasquez, Alexa Alaniz, Robert K. Dearth, Rupesh R. Kariyat
Biology Faculty Publications and Presentations
In weeds, disturbance has been found to affect life history traits and mediate trophic interactions. In urban landscapes, mowing is an important disturbance, and we previously showed that continuous mowing leads to enhanced fitness and defense traits in Solanum elaeagnifolium, Silverleaf Nightshade (SLN). However, most studies have been focused on foliar defenses, ignoring floral defenses. In this study we examined whether continuous mowing affected floral defenses in SLN using mowed and unmowed populations in South Texas, their native range. We found flowers of mowed SLN plants larger but lighter than unmowed plants. Additionally, flowers on plants that were mowed …

In this activity, students will use an AI Image Generator to create a grid of images of the same organism and identify a series of traits that vary to build a possible phylogenetic tree.
Alfred Russel Wallace Notes 30. Wallace A Theist? Part I., Charles H. Smith
Alfred Russel Wallace Notes 30. Wallace A Theist? Part I., Charles H. Smith
Faculty/Staff Personal Papers
Alfred Russel Wallace (1823−1913) has been portrayed as a ‘theist’ on a large number of occasions from his own time on to the present. In this, the first of a two part work, this assessment is questioned. In part one, the matter of Wallace’s personal philosophy and spiritual orientation is explored, the conclusion being that Wallace was a lifelong agnostic who can hardly be aligned with theism.
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 …

Climate Change-Associated Declines In Water Clarity Impair Feeding By Common Loons, Walter H. Piper, Max R. Glines, Kevin C. Rose
Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
Climate change has myriad impacts on ecosystems, but the mechanisms by which it affects individual species can be difficult to pinpoint. One strategy to discover such mechanisms is to identify a specific ecological factor related to survival or reproduction and determine how that factor is affected by climate. Here we used Landsat imagery to calculate water clarity for 127 lakes in northern Wisconsin from 1995 to 2021 and thus investigate the effect of clarity on the body condition of an aquatic visual predator, the common loon (Gavia immer). In addition, we examined rainfall and temperature as potential predictors …
Assessing Biological Condition Of Restored Streams In An Agriculturally Impaired Chesapeake Bay Sub-Watershed, Julia M. Portmann, Bruce Wiggins
Assessing Biological Condition Of Restored Streams In An Agriculturally Impaired Chesapeake Bay Sub-Watershed, Julia M. Portmann, Bruce Wiggins
Department of Biology - Faculty Scholarship
Intensive agricultural practices can be detrimental to aquatic biological conditions; however, restoration such as removing livestock and creating in-stream habitat can strengthen biotic communities. Smith Creek, a sub-watershed of the Chesa- peake Bay, was designated a showcase watershed in 2010 by the United States Department of Agriculture to demonstrate the efficacy of widespread restoration. Our study sought to follow up on these efforts by assessing the individual and combined impacts of restoration, habitat, and land cover on aquatic macroinvertebrate communities in Smith Creek. We predicted that longer-restored sites, sites with less surrounding pasture, and streams with larger substrate size would …
Ecotheology In Context: A Critical Phenomenological Study Of Graduates Of Environmentally Focused Seminary Programs In The United States Of America, Cherice Bock
Antioch University Full-Text 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 …
Pollinator Communities And Their Ecosystem Services At Conservation Grasslands And Adjacent Croplands, Araceli Gomez Villegas
Pollinator Communities And Their Ecosystem Services At Conservation Grasslands And Adjacent Croplands, Araceli Gomez Villegas
Department of Entomology: Dissertations, Theses, and Student Research
Pollinators are intrinsically linked to the success of unmanaged and managed ecosystems by providing pollination services that aid in the reproduction of wildflowers and many crops. Land use change, habitat loss, fragmentation, and related landscape-level phenomena (for example, increased pesticide exposure) threaten pollinators and have been associated with population declines. In the Midwestern region of the United States, land conversion of native prairies and grasslands to row-crop agriculture has been one of the largest contributors to pollinator habitat loss. Conservation programs, such as the Conservation Reserve Program, have worked towards removing environmentally sensitive lands from agriculture production and enrolling them …

Oystershell Scale (Hemiptera: Diaspididae) Population Growth, Spread, And Phenology On Aspen In Arizona, Usa, Connor D. Crouch, Richard W. Hofstetter, Amanda M. Grady, Nylah N.S. Edwards, Kristen M. Waring
Aspen Bibliography
Oystershell scale (OSS; Lepidosaphes ulmi L.) is an invasive insect that threatens sustainability of aspen (Populus tremuloides Michx.) in the southwestern United States. OSS invasions have created challenges for land managers tasked with maintaining healthy aspen ecosystems for the ecological, economic, and aesthetic benefits they provide. Active management is required to suppress OSS populations and mitigate damage to aspen ecosystems, but before management strategies can be implemented, critical knowledge gaps about OSS biology and ecology must be filled. This study sought to fill these gaps by addressing 3 questions: (i) What is the short-term rate of aspen mortality in …
Effects Of Hemiparasites In Grassland Restorations Are Not Universal, Anna Marie Scheidel, Victoria Borowicz
Effects Of Hemiparasites In Grassland Restorations Are Not Universal, Anna Marie Scheidel, Victoria Borowicz
Faculty Publications – Biological Sciences
Root hemiparasites infiltrate the vascular tissue of host roots to acquire water and nutrients, which often reduces host growth. Hemiparasites are postulated to be keystone species in grassland communities if they suppress dominant species and increase plant community biodiversity, and ecosystem engineers if they increase nutrient accessibility for surrounding species. We examined keystone effects by evaluating species richness and evenness in 1 m2 plots in a recent prairie restoration where Castilleja sessiliflora was naturally present or absent, and in a longer-established prairie restoration with or without Pedicularis canadensis. We examined ecosystem engineer effects by determining nitrate and phosphate concentrations …

Taxonomic Advances Driven By The Genomic Analysis Of Butterflies, Jing Zhang, Qian Cong, Jinhui Shen, Leina Song, Nick V. Grishin
The Taxonomic Report of the International Lepidoptera Survey
This study presents new findings based on a large-scale analysis of butterfly genomic sequences. Focusing on species identification through comparative genomics, we define subspecies as populations differentiated to a lesser extent than distinct species ("species in the making"). Additionally, we propose further adjustments to the current butterfly classification. As a result, 3 subgenera, 12 species, and 4 subspecies are described as new. New subgenera are (type species in parenthesis): Hyalaus Grishin, subgen. n. (Papilio epidaus E. Doubleday, 1846) of Eurytides Hübner, [1821] (Papilionidae Latreille, [1802]) and Astria Grishin, subgen. n. (Lycaena astraea Freyer, 1851) of Glaucopsyche Scudder, 1872 …

Pile Burning After Conifer Removal From Aspen Stands Affects Tree Mortality, Regeneration, And Understory Recovery, John-Pascal Berrill, Christa M. Dagley, Yoon G. Kim, J. Morgan Varner
Aspen Bibliography
Quaking aspen (Populus tremuloides Michx.) stands throughout the western United States provide valuable ecosystem services but can be lost via succession from aspen to conifer. Forest managers are cutting conifers, but disposal of cut wood can be challenging in remote or sensitive areas. Piling and burning is being tested within aspen stands but ecosystem responses to this treatment are understudied. We assessed aspen tree mortality, tree regeneration, and understory vegetation after forest restoration thinning followed by pile burning in seven aspen-conifer stands around Lake Tahoe, California and Nevada, USA. Pile burning was conducted after cut wood had dried (1.5–7.5 …
Comparing Sucrose Preference Between Colonies Of Bombus Impatiens, Kevin R. Corrigan, Becky Hansis-O'Niell, Aimee Sue Dunlap
Comparing Sucrose Preference Between Colonies Of Bombus Impatiens, Kevin R. Corrigan, Becky Hansis-O'Niell, Aimee Sue Dunlap
Undergraduate Research Symposium
Current studies in nectar concentration preference generally take the form of a static laboratory experiment in which a multitude of feeders provide a constant source of nectar in differing concentrations and data is collected on which one is preferred most by bees. Studies like these are important because they seek to gain an understanding of bee foraging patterns. Having a strong biological understanding of these organisms better prepares us to combat issues regarding conservation should they occur. Here, we conduct an analysis on the foraging patterns of two colonies of Bombus impatiens (B. Impatiens) with data gathered from fixed ratio …
Animal Conservation In St. Louis, Kate O'Sullivan
Animal Conservation In St. Louis, Kate O'Sullivan
Undergraduate Research Symposium
St. Louis has a multitude of organizations involved in the natural sciences. But how many of them actually contribute towards animal conservation? The St. Louis Zoo is an organization that focuses a lot of its effort on presentation, so how does that impact the funds that go towards actually saving the animals? I plan to dive into the different animal-based organizations in St. Louis and its surrounding areas, as well as discuss the positives and negatives of each organization. Furthermore, I will provide examples from several sources that I have been reviewing all year to support my claims. I plan …
Surveys Of Aphonopelma Hentzi In Missouri: Conservation Efforts Through Population, Genetics, And Habitat Studies, Anderson B. Spencer Mr., Becky Hansis-O'Niell
Surveys Of Aphonopelma Hentzi In Missouri: Conservation Efforts Through Population, Genetics, And Habitat Studies, Anderson B. Spencer Mr., Becky Hansis-O'Niell
Undergraduate Research Symposium
Aphonopelma hentzi and other tarantula species are greatly understudied organisms. In the Missouri regions there is little knowledge on their mating patterns, gene diversity, or population sizes. The focal glades in this experiment display regional fragmentation, which could prevent tarantulas from traveling and mating between regions of their glades. Due to the lack of knowledge surrounding them, methods for determining gene diversity are harmful to the organism. Our recent work has shown that it is possible to extract genetic information from the molts of burrowing tarantulas. This will allow us to safely determine the lineages and interbreeding patterns of the …
Aspen And Spruce Densities Affect Tree Size, Future Stand Volume, And Aboveground Carbon Following Precommercial Thinning, Philip G. Comeau, Mike Bokalo
Aspen And Spruce Densities Affect Tree Size, Future Stand Volume, And Aboveground Carbon Following Precommercial Thinning, Philip G. Comeau, Mike Bokalo
Aspen Bibliography
Data collected over a 30-year period from an experiment replicated across 21 locations in western Canada are used to explore the effects of precommercial thinning of trembling aspen to a range of densities in combination with three initial white spruce densities on tree growth and stand dynamics. Increasing differentiation amongst the 15 treatments was observed with age after thinning for both spruce and aspen responses. Spruce height and diameter declined with increasing aspen density. At age 10 spruce diameter with no aspen was 1.5× that of spruce in unthinned while it was 2.6× that of spruce in unthinned at age …

Tracing The Maternal Line In Glacial-Interglacial Migrations Of Populus Tremuloides: Finding Trees For Future Sustainable Forests By Searching In The Past, Luke R. Tembrock, Frida A. Zink, Guozhe Zhang, Andrea Schuhmann, Cuihua Gu, Zhiqiang Wu
Aspen Bibliography
Maintaining and planting sustainable forests is fundamental in perpetuating the essential functions of these ecosystems. A central aspect of managing forests for future resilience is the consideration of past migration and evolution of trees using genetic and genomic data to ensure that functionally appropriate diversity is conserved and utilized. In our study, we generated and compared genetic and genomic data from the plastome to better understand phylogeography and molecular evolution in the tree species Populus tremuloides (aspen). With these analyses, we found evidence of divergence and migration between northern and southern sites. Additionally, evidence of deep incomplete plastome sorting across …
