Use Of Intramodal Odor Cues In Shelter Recognition By An Amblypygid, Nathan Bostelman
Use Of Intramodal Odor Cues In Shelter Recognition By An Amblypygid, Nathan Bostelman
Honors Projects
Amblypygids are nocturnal arthropods which live in cluttered habitats and possess the ability to navigate home after displacements of up to ten meters. Homing amblypygids rely on olfactory and tactile information gathered by their antenniform legs to navigate successfully. Given that odor signals encountered in nature are complex and dynamic, navigation via olfaction presents unique challenges related to signal uncertainty. To understand how amblypygids perceive perceive complex odors and what they learn from them, individuals of the subtropical amblypygid P. marginemaculatus were trained to associate a blend of two odors with a shelter and tested on three treatments: the reinforced …
Function Of Spiny Dorsal Fin Erector Muscles In The Bluegill, Lepomis Macrochirus, Zakiyat Djabakatie
Function Of Spiny Dorsal Fin Erector Muscles In The Bluegill, Lepomis Macrochirus, Zakiyat Djabakatie
Honors Projects
Local motor control directly contributes to stability, which can be compromised by injury or multiple neuromuscular disorders. In addition, lack of sensory perception as experienced by decreased limb sensation can further deteriorate one‚Äôs quality of life. The goal of this study is to use bluegill (Lepomis macrochirus) fins as model systems to study and gain insights on local motor control and sensory perception to improve stability and locomotion in humans, especially in a rehabilitative state. We hypothesize that 1) when exposed to turbulence (T), bluegill will use the spiny dorsal fin to recover stability and muscle intensity and duration will …
Too Little Ph: How Freshwater Acidification Impacts The Abundance Of Macrophytes Consumed By Rusty Crayfish, Lauren Tucker, Paul Moore Dr., Jay Jones Mr.
Too Little Ph: How Freshwater Acidification Impacts The Abundance Of Macrophytes Consumed By Rusty Crayfish, Lauren Tucker, Paul Moore Dr., Jay Jones Mr.
Honors Projects
Anthropogenic activities such as the burning of fossil fuels result in increased atmospheric carbon dioxide (CO2) concentration. High levels of atmospheric CO2 cause chemical shifts in the carbon cycle. Changes in the carbon cycle due to increased CO2 levels lead to ocean and freshwater acidification. Freshwater acidification is problematic for species that synthesize their own shells as well as species that use olfaction for decision-making. Rusty crayfish (Faxonius rusticus) were subject to simulated freshwater acidification and fed two types of macrophyte, Chara (Chara braunii) and Myriopyllum (Myriophyllum sibiricum). A series …
Aortic Pressure And Heart Rate In The Lobster Homarus Americanus Are Modulated By Mechanical Feedback And Neuropeptides, Grace Marie Hambelton
Aortic Pressure And Heart Rate In The Lobster Homarus Americanus Are Modulated By Mechanical Feedback And Neuropeptides, Grace Marie Hambelton
Honors Projects
Baroreceptors are stretch receptors located in the aorta of mammals; in response to increased afterload, they elicit a decrease in heart rate, creating a negative feedback loop that lowers blood pressure. Although lobsters (Homarus americanus) do not have baroreceptors like mammals, closely related land crabs have been shown to have baroreceptor-like responses. Heart contraction is also regulated by the Frank-Starling response, where increasing stretch or preload increases the contractile force of the heart. In addition to these types of biomechanical modulations, lobsters use a central pattern generator, the cardiac ganglion, to maintain synchronicity of the heartbeat. The heart …
Impact Of Endangered Animal Protection Rights, Policies, And Practices On Zoonotic Disease Spread, Daniella Fedak-Lengel
Impact Of Endangered Animal Protection Rights, Policies, And Practices On Zoonotic Disease Spread, Daniella Fedak-Lengel
Honors Projects
Building on field research in Costa Rica and Belize, this honors project analyzes environmental and endangered animal protection policies, rights, and practices in Central America and the Caribbean, and assesses the impact of veterinary science and biological research and practice, particularly conservation biology, on animal welfare concerns. Informed by the recent surge in awareness regarding zoonoses and zoonotic disease transmission, prevention and control, resulting from the current global pandemic of SARS-CoV-2, the project assesses the need for new and innovative types of collaboration, particularly involving conservation biologists, environmental scientists, public health experts, law and policy makers, and global trade and …
Vegetative Rapid Assessment And Habitat Quality Analysis Of Steidtmann Woods, Sarah Mae Bail
Vegetative Rapid Assessment And Habitat Quality Analysis Of Steidtmann Woods, Sarah Mae Bail
Honors Projects
Due to invasive species and the assumption of an unhealthy ecosystem, Steidtmann Woods is an underutilized piece of land owned by Bowling Green State University. However, the property had never been analyzed. The proposed hypothesis was that Steidtmann was indeed in destress and its ecosystem could benefit from intervention—removal of invasive species and supplementation of natives. Through a rapid vegetative analysis, data was collected in several regions of the woods to identify what navies and non-natives were present as well as to identify their proportions. With that data, the species evenness, richness, and diversity was calculated; first, with raw field …
