A Baseline Assessment Of Migratory And Resident Bird Use Of A Prairie Restoration Site In Eastern Washington, Madilyn J. Odiorne, Brynn A. Richey, Ruby L. Hammond

2023 Symposium

Prairies, and other types of grassland ecosystems, have suffered some of the most profound losses worldwide, due to anthropogenic factors such as fossil fuel extraction, agriculture, and climate change. Likewise, organisms inhabiting grassland ecosystems have become extirpated across much of their historical range, not the least of which has been a 50% decline in grassland birds since the 1960s. In response to losses of intact prairie in eastern Washington, a 120-ac site has been established on the EWU campus to regenerate native prairie and monitor changes in the ecosystem as native plants recolonize and replace non-natives. Because birds are an …

Mowing Cattail Cover To Increase Aquatic Vegetation Diversity On The Coeur D’Alene River Floodplain In Cataldo, Idaho, Makenna J. Tabino

2023 Symposium

The Schlepp Easement is a 400 acre wetland on the Coeur D’Alene River floodplain, near Cataldo, Idaho. The wetland has been restored to protect it from heavy metal pollution transported downstream from mining sites near Kellogg, Idaho, the location of the Bunker Hill EPA Superfund Site. This wetland was restored to provide safe habitats and feeding grounds for migratory waterfowl and to maintain wetland biodiversity. However, cattail is prone to becoming overdominant and outcompeting other plants, which greatly limits a wetland’s biodiversity. Our objectives were to test whether aquatic boat mowing can reduce cattail cover, improving species diversity and cover …

Zebrafish Feeding And Breeding: Adapting Best Practices For Zebrafish Husbandry, Abbigale Sullins

Scholars Day Conference

Zebrafish (Danio rerio) are a tropical, freshwater fish that serve as a key research model for human health and disease. The anatomical and genetic similarities shared by humans and zebrafish make establishing a zebrafish laboratory advantageous for undergraduate research and coursework. Zebrafish feeding protocols utilize two primary food types: dry (flake or pelleted) food and live prey such as artemia (brine shrimp) or rotifers. Adopting a feeding protocol that incorporates both dry and live feed optimizes considerations of nutrition and cost for maintaining healthy fish. Best practices for feeding were adapted from authoritative sources in the current literature and published …

Acoustic Sampling Of Arkansas Bat Species Richness Across Different Seasons And Habitats, Lark E. Sybrant

ATU Research Symposium

Arkansas is home to sixteen bat species belonging to the Vespertilionidae and Molossidae families. Bats are keystone species and provide numerous ecosystem services that also benefit people. This study explores factors that impact species richness between the spring and fall seasons in a wooded rural site (Washburn Park) and an urban field site (Arkansas Tech University campus), Russellville, AR. The non-invasive Echo Meter Touch 2 Pro, from Wildlife Acoustics, was used to record calls and identify bat species from these locations. Nearly 1,050 calls were recorded from 11 different species across the spring and fall between both sites. Results showed …

Environmental Factors Affecting Coleoptera Biomass In The Ozark Mountain Range In Arkansas, Hayley J. Springsteen

ATU Research Symposium

Abstract:

Terrestrial invertebrates including species of Coleoptera (beetles) play an important role in many ecosystem services including soil formation and fertility, pollination, decomposition and nutrient turnover, population regulation of other organisms through predation. Coleoptera are often vital in determining biodiversity and conservation techniques. The purpose of this study is to contribute to the knowledge of how environmental factors and different management practices are affecting Coleoptera populations and further assist ecologists in improving management techniques in the future. The insect data in this study was collected over the course of two weeks in the Arkansas portion of the Boston Mountain range. …

Analysis Of The Population Structure And Migration Habits Of The Northern Leopard Frog (Lithobates Pipiens) At Midewin National Tallgrass Prairie, Gretchen A. Brinkman

Scholar Week 2016 - present

Massive amphibian declines of recent years have pushed researchers to pursue population genetics surveys and to assess the status of these essential components of many ecosystems. The Northern Leopard Frog (Lithobates pipiens) has been continuously experiencing population declines across the continental United States due to a combination of habitat loss and environmental change. Midewin National Tallgrass Prairie houses a considerable portion of Northern Leopard Frog (L. pipiens) in Illinois, and within this location, two creeks provide ideal conditions to support these animals. Because this prairie restoration project is a relatively recent development, further assessments on the …

"In The Beginning, God Created Atoms", Samiya L. Henry

Undergraduate Research and Scholarship Symposium

Genesis 1:1 states “In the beginning, God created the heavens and the earth.” This is the defining statement in the Bible and acts as the foundation of creation and God’s power in the Christian faith. On the other hand, many scientists believe the Big Bang Theory and the discoveries made in other fields of science solely define the creation of the universe and explain life as we know it, also disproving the Christian creation story and the overall existence of God. However, the exact opposite is true; God is science.

Alone, neither of these concepts (faith and science) fully solve …

Adaptive Plasticity Of Coloration In Response To Environmental Change, Karissa Coffield

Scholars Week

When rapid environmental changes occur, different selective forces can create phenotypic trade-offs in which a trait can provide fitness benefits or costs under different environmental conditions. Amphibians are particularly vulnerable to environmental change, and previous research has revealed that some species will plastically respond to variation in temperature and ultra-violet radiation (UVR) by altering their coloration. Divergent selection on coloration may change with elevation and climate induced shifts in temperature because high temperatures are likely to result in lighter color morphs but as elevation increases, UVR exposure increases leading to the prediction that darker color morphs will be more common. …

Heterospecific Anural Eavesdropping Cues, Lucia C. Maldonado, Hayley Lunn, Max Sprute, Andrew Wang, Ripley Conklin, Nolan Gentile, Conor Kramer, Lee Kats

Seaver College Research And Scholarly Achievement Symposium

The ability to communicate within species is a trait utilized by every organism. Using cues conspecifically creates a better chance of survival for other members of the species and increases fitness overall. However, using cues heterospecifically also poses a great advantage as animals can eavesdrop on cues released by another species. Previous studies have recorded that eavesdropping is beneficial to prey species, such as squirrels reacting to bird calls and tadpoles reacting to visual and chemical cues to avoid predation. We asked how one local and one exotic species of frog would respond to cues emitted by another local species …

Diversification And Convergence Following The Transition From Saltwater To Freshwater In Stingrays, Autumn D Magnuson

2023 Midwest Ecology & Evolution Conference

One of the most fundamental questions in biology is why some groups of organisms are more diverse than others. Classic hypotheses for explaining differences in diversity consider distinctions in time, place, resources, and competitors as the staging grounds for differential diversification. Freshwater and saltwater environments have similar levels of diversity despite significant differences in size, so studying transitions between the two systems can provide insights into evolutionary processes. Despite the challenges associated with this transition, stingrays have invaded freshwater habitats multiple times across different continents, making them useful for better understanding these systems. In this study, we evaluated the frequency …

Evolution Of A Genus Of Gall Wasp Kleptoparasites, Guerin E. Brown

2023 Midwest Ecology & Evolution Conference

Kleptoparasites do not directly parasitize their hosts but instead steal food and resources, reducing host fitness. Like direct parasites, kleptoparasites can be highly dependent on their hosts such that their evolutionary histories may be linked. Here, we study the evolution of a kleptoparasitic wasp genus, Synergus (Hymenoptera: Cynipidae: Synergini), in relation to their hosts, oak gall wasps (Hymenoptera: Cynipidae: Cynipini). Ovipositing oak gall wasps induce the formation of galls on oaks (Fagaceae) that provide food and shelter to one or more developing gall wasps. Galls induced by different gall wasp species are diverse in size, shape, color, and location …

Environmental Factors Shaping A Sawfly-Associated Community Of Parasitoids, Carson Kephart, Robin K. Bagely

2023 Midwest Ecology & Evolution Conference

A major goal of evolutionary biology is to understand the mechanisms that shape biodiversity, especially amongst highly speciose lineages such as parasitic wasps. However, most of these lineages are poorly described, with very little available natural history information. This lack of information limits our ability to uncover the environmental factors that contribute to their patterns of divergence, distribution, and abundance. To that end, here we take advantage of a community of hymenopteran parasites that has an unusually large amount of available information since they attack an economically important pine sawfly species, Neodiprion lecontei. We build upon a set of …

Patterns Of Neural Investment In Sensory Modalities Of Tropical Canopy And Understory-Dwelling Ants (Pseudomyrmex), Daniella Prince

2023 Midwest Ecology & Evolution Conference

The neuroanatomy of insects reflects functional roles and cognitive capabilities. The high energetic cost of the development and maintenance of neural tissue constrains investment in brain compartments that receive and process sensory input. Thus, differential investment in sensory compartments should parallel selective pressures, including significant habitat parameters. We tested the hypothesis that ants occupying different vertical rainforest strata exhibit differential investment in visual and olfactory brain regions. We used confocal microscopy to examine immunostained brains of species with distinct nesting and foraging preferences: Pseudomyrmex boopis (understory; U), P. gracilis (understory and canopy; UC), and P. oculatus (canopy; C). We created …

Effects Of Duckweed On Mosquito Oviposition And Larval Survivorship, Alyssa Gushka

Capstone Showcase

Invasive species are those non-natives to habitat and that negatively impact the environment or human health problems. Invasive mosquitoes threaten the environment and humans, as they transmit 17% of infectious diseases including malaria, West Nile virus and yellow fever. Aedes japonicas and Aedes albopictus are invasive mosquitoes that often deposit eggs in artificial containers. Chemical pesticides, such as Bacillus thuringiensis israelensis (BTI), utilizes endospores to release toxins into the larvae. However, BTI creates negative consequences for the environment and other species. Many plants are being examined to see if they can act as natural pesticides. Duckweeds are native to North …

Guano Among Bat Species From Two Regions Shows Influence Of Geography And Diet On Bacterial Community, Rahma Ahmed, Thomas Mcelroy, Shannon Whitney, Lydia Moore

Symposium of Student Scholars

Studies of bat guano have shown that the diversity and structure of associated microbial communities can be related to factors such as host phylogeny, life history and reproductive stage, geography, and diet. Many insectivorous bat species in the southeastern U.S. have generalist diets that may shift seasonally to take advantage of abundant prey species or maximize caloric intake. Seasonal shifts in prey availability or consumption should be reflected in a guano microbiome change. We also expected to detect distinct guano microbiomes within species. Within species, distinct microbial communities related to geography, and finally life history and reproductive stage. We compared …

Insect Availability And Parental Care Behavior In A Common Bird, Cole Bourque

Symposium of Student Scholars

Populations of aerially insectivorous birds are declining throughout North America. Urbanization may indirectly contribute to this decline through its negative effects on populations of insects, an important food source in insectivores' diets, where low insect availability may be especially challenging for birds during breeding. How fluctuations in insect populations impact various species at higher trophic levels is an important area of current study for future conservation biology. Here, we examine whether nestling provisioning, brooding and guarding behaviors in a breeding bird—the European starling (Sturnus vulgaris)—may be altered depending on the relative insect availability in the environment. We found …
