Using Edna To Assess Impacts Of Oyster Restoration On Ecosystem Biodiversity At A Heavily Impacted Coastal Lagoon, Dominique Di Domenico, Emily Bonacchi, Elizabeth Suter 2024 Student presenter

Using Edna To Assess Impacts Of Oyster Restoration On Ecosystem Biodiversity At A Heavily Impacted Coastal Lagoon, Dominique Di Domenico, Emily Bonacchi, Elizabeth Suter

Molloy Multidisciplinary Undergraduate Research Conference

The Great South Bay (GSB), a bar-built, temperate, coastal lagoon on the south shore of Long Island, New York, USA, is a highly modified estuary due to heavy urbanization and suburbanization in the last century. GSB historically provided up to 50% of the nation’s hard clam (Mercenaria mercenaria) harvest, and is the legal home of the “Blue Point” oyster (eastern oyster; Crassostrea virginica). However, due to overexploitation as well as persistent stress from ongoing nitrogen pollution and harmful algal blooms, shellfish populations are fractions of their original abundances. Restoration efforts in GSB, driven both by community efforts …

Trophic Ecology Of Black Swallowers (Scombriformes: Chiasmodontidae: Chiasmodon) In The Deep-Pelagic Gulf Of Mexico, Travis J. Kirk 2024 Nova Southeastern University

Trophic Ecology Of Black Swallowers (Scombriformes: Chiasmodontidae: Chiasmodon) In The Deep-Pelagic Gulf Of Mexico, Travis J. Kirk

All HCAS Student Capstones, Theses, and Dissertations

The ecology of deep-pelagic predatory fishes remains poorly understood despite their importance as ecosystem regulators and energy transfer vectors. This study investigated the trophic ecology of three species of the predatory fish genus Chiasmodon (“black swallowers”) in the Gulf of Mexico, a region that serves as an analog for the global low-latitude deep pelagial, the world’s largest cumulative ecosystem. Foraging habits (e.g., selectivity, chronology, daily ration) of an “advanced” evolutionary fish in a system that is otherwise dominated by basal fish taxa, were quantitatively estimated via high-resolution stomach content analysis. A quantitative dataset of both predator and prey abundance, the …


Understanding Mechanisms Underlying Changes In Parental Care Behaviour In Response To Perceived Paternity In Sunfish, Emma Churchman 2024 Western University

Understanding Mechanisms Underlying Changes In Parental Care Behaviour In Response To Perceived Paternity In Sunfish, Emma Churchman

Electronic Thesis and Dissertation Repository

Parental care is essential for the survival of many young animals but presents significant costs to the caring parent. To mitigate these costs, parental care systems have evolved to optimize survival and fitness. According to parental investment theory, care allocation is influenced by the offspring’s value, which is often linked to their relatedness to the parent. In this thesis, I explore how hormones and gene expression influence parental care, focusing on bluegill sunfish (Lepomis macrochirus) and the hybrids they produce with pumpkinseed sunfish (Lepomis gibbosus). By manipulating direct and indirect paternity cues – swapping eggs between …


The Decline In Monarch Butterfly, Danaus Plexippus, Populations: An Example Of The Global Threat To Biodiversity, Olivia Sidoti 2024 Bowling Green State University

The Decline In Monarch Butterfly, Danaus Plexippus, Populations: An Example Of The Global Threat To Biodiversity, Olivia Sidoti

Honors Projects

Biodiversity encompasses the variety of all life on Earth and how these aspects of nature interact with each other. To have stable and abundant biodiversity, vast amounts of species and organisms are required within an ecosystem. As a result of the increase in negative impacts of human activities and behaviors on the health of nature, biodiversity has been decreasing. An example of the decrease in biodiversity is depicted by the recent decline of the monarch butterfly species. The monarch butterfly is an iconic North American insect that is experiencing a decline in its population due to threats such as deforestation, …

Euscorpius

Two new monotypic buthid genera are described: Sanaag gen. n. and Sahil gen. n. from Somaliland, both belonging to the ‘Buthus’ group. Sanaag gen. n. (type species Gint maidensis Kovařík et al., 2018) differs from Gint Kovařík et al., 2013 in the structure of its hemispermatophore, which has a large, tall, subtriangular hook-like basal lobe, and in the shape of its telson which is rather bulbous. Sahil gen. n. (type species Sahil elmii sp. n.) differs from all morphologically similar small-sized genera of the Horn of Africa in having the ventral aspect of cheliceral fixed finger with two denticles, …


Length-Weight Relationship Of Flier (Centrarchus Macropterus) In Moro Creek, Jeffrey G. Phillips 2024 Arkansas Tech University

Length-Weight Relationship Of Flier (Centrarchus Macropterus) In Moro Creek, Jeffrey G. Phillips

ATU Research Symposium

Length-weight relationships provide foundational knowledge for managing fisheries populations. However, there are many species where the length-weight relationships are not widely understood. The Flier (Centrarchus macropterus) is one species where there is a lack of information regarding its length-weight relationship and spatial variation associated with this relationship. A new study was needed to assess the length-weight relationship for this species. Fliers were collected from upper Moro Creek during October 2023. Multiple gears (backpack electrofishing and seining) were employed to increase detection of this species. Length (mm), and weight (g) were recorded for every individual observed. A total of 85 Flier …

A Survey Of Mussels In Small Tributaries Of The Ouachita River Headwaters, Aaron J. Huckeba, Seth Drake, Kendall Moles, Risa Mccollough, Nathan Mansor

ATU Research Symposium

Understanding species distributions is of utmost importance for effective conservation of aquatic resources. Freshwater mussels are among the most imperiled taxonomic groups as they are experiencing rapid declines in the southeastern United States. Standard mussel surveys are typically conducted on larger streams and rivers, leaving small headwater tributaries unsampled. Our study looked to document mussels in headwater tributaries of the Ouachita River watershed. We conducted standardized time-based surveys at 19 sites across nine tributaries using snorkeling, grubbing, and raking methodologies in the summer of 2023. Furthermore, we collected measurements on water quality (pH, conductivity, salinity, total dissolved solids, and temperature) …

Changes In Animal Vocalizations In Response To A Total Solar Eclipse, Colton W. Morris

ATU Research Symposium

My proposed research project will study the changes in animal vocalizations in response to the total solar eclipse that will take place in Russellville, Arkansas, on April 8, 2024. I will use audio recordings before, during, and after the eclipse to quantify changes in animal vocalizations. Most recordings will be in the range of normal hearing, and will primarily detect birds, frogs, and insects. Additionally, I will deploy one ultrasonic recorder capable of detecting bats. From these recordings I will be able to quantify overall and species-specific call rates. Audio recordings will be paired with continuous measurements of light intensity …


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

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 …


Water Lily Leaf Beetle Ecology On Hourglass Lake In Big Lake, Alaska, Haley Lloyd, Grace Beatty 2024 Olivet Nazarene University

Water Lily Leaf Beetle Ecology On Hourglass Lake In Big Lake, Alaska, Haley Lloyd, Grace Beatty

Scholar Week 2016 - present

The Water-Lily Leaf beetle, Galerucella nymphaeae, is a beetle commonly found on Western Pond Lily pads, Nuphar lutea, in Hourglass Lake. Hourglass Lake is located in Big Lake, Alaska. This area is surrounded by boreal forest and bogs and is situated roughly twenty miles North of Anchorage. Within this ecosystem, the Water-Lily Leaf Beetle and the Western Pond Lily are intrinsically linked, as the lily pads serve as a site of feeding and reproduction for the beetles. Dr. Derek Rosenberger of Olivet Nazarene University noticed an abundance of these beetles as he was kayaking through Hourglass Lake, and a project …


Rescape: Transforming Coral-Reefscape Images For Quantitative Analysis, Zachary Ferris, Eraldo Ribeiro, Tomofumi Nagata, Robert van Woesik 2024 Florida Institute of Technology

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 …


A Comparative Study Of Butterfly And Bumblebee Communities At The Onu Prairie And Perry Farm, Kathryn S. Bell 2024 Olivet Nazarene University

A Comparative Study Of Butterfly And Bumblebee Communities At The Onu Prairie And Perry Farm, Kathryn S. Bell

Scholar Week 2016 - present

The decline in many pollinator communities has been a topic of great concern for many years. The primary causes of these declines are habitat loss from urbanization and agriculture, pesticide usage, and climate change. Surveys of pollinator populations are important because they can help determine the health of the pollinator communities. No systematic surveys have assessed the pollinator populations at Olivet Nazarene University’s Prairie or at the LaGesse Prairie at Perry Farm Park in Bourbonnais Township, IL. Thus, little is known about the abundance or the species richness of bumble bees or butterflies in these areas. To address this lack …

Effects Of Fungal Biopesticide Doses On Mortality In Bumble Bees, Colton Burris 2024 University of Missouri, St. Louis

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 …


A Novel Study Of Cliff Swallow (Petrochelidon Pyrrhonota) Feather Coloration In Relation To Habitat Characteristics, Colony Size, And Body Condition, Sonja Brandt, Medhavi Ambardar 2024 Fort Hays State University

A Novel Study Of Cliff Swallow (Petrochelidon Pyrrhonota) Feather Coloration In Relation To Habitat Characteristics, Colony Size, And Body Condition, Sonja Brandt, Medhavi Ambardar

SACAD: John Heinrichs Scholarly and Creative Activity Days

Feather coloration is used for social signaling in many avian species, and can be associated with their ability to live and breed in habitats with high quality resources (Jenkins et al. 2013, Saino et al. 2013). It can signify individual quality, (Saino et al. 2013) and influence mate choice (Bennet et al. 1996). We analyzed different aspects of Cliff Swallow (Petrochelidon pyrrhonota) feather coloration in relation to morphology and habitat characteristics. We measured luminance, hue (theta and phi), and saturation for four different color patches on the swallows. We predicted that individuals in brighter coloration would be able to settle …

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 2024 University of Arkansas, Fayetteville

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 …
