Modeling Oyster Growth Dynamics In Flupsy Systems To Develop A Decision Support Tool For Seed Management, Gretchen Clauss Jan 2023

Modeling Oyster Growth Dynamics In Flupsy Systems To Develop A Decision Support Tool For Seed Management, Gretchen Clauss

Honors Projects

As the Gulf of Maine warms and lobsters move north to colder waters, Maine’s working water front has begun to diversify. There is a thriving new ecosystem of aquaculturists looking to keep Maine’s waterfront traditions alive in a lasting, sustainable way. One of the most popular aquaculture industries is oyster farming. With an increasing number of oyster farms developing in Midcoast Maine each year, we seek to develop a decision support tool to aid farmers in seed management. Oyster farmers can choose weather or not to use an upweller on their farm, and our goal is to provide guidance on …


Functional Redundancy Of A Non-Native Foundation Species (Eelgrass, Zostera Japonica) Across Intertidal Stress Gradients, S. Maria Garcia Jan 2023

Functional Redundancy Of A Non-Native Foundation Species (Eelgrass, Zostera Japonica) Across Intertidal Stress Gradients, S. Maria Garcia

Honors Projects

Non-native species foundation species can alter ecosystems in both positive and negative ways. The creation of habitat can be beneficial to native species when they provide a limiting resource or in a stressful environment. Yet this creation of habitat can also be detrimental by replacing native species and/or facilitating the presence of more non-native species. In Willapa Bay, WA, a non-native foundation species, Zostera japonica, co-exists with the native foundation species Zostera marina. Zostera japonica persists at the higher intertidal in monocultures, the two species overlap in the mid intertidal, and Z. marina persists in monocultures in the low intertidal. …


The Fear Of Reptiles And How To Change It, Maxwell Lyman Dec 2020

The Fear Of Reptiles And How To Change It, Maxwell Lyman

Honors Projects

Reptile fear is prominent across many cultures. Anti-reptilian attitudes can lead to anti-conservation attitudes towards reptiles. Person-animal interaction has been shown to decrease fear desensitization and increase positive attitudes towards "unpopular" animals. My project demonstrates the effectiveness of live animal presentation in dispelling negative attitudes of reptiles. However, due to the sample size of the project, further research is highly suggested.


The Ability Of Thaumoctopus Mimicus To Be Operantly Conditioned To A Sound Stimulus, Stephanie Wittman May 2020

The Ability Of Thaumoctopus Mimicus To Be Operantly Conditioned To A Sound Stimulus, Stephanie Wittman

Honors Projects

This paper focuses on the ability of the mimic octopus Thaumoctopus mimicus to be operantly conditioned to an auditory stimulus. The octopus is known to be the most advanced of the invertebrates and has learning abilities that are comparable to vertebrates in spite of their differences in brain structure. These animals have been shown to react to visual and tactile stimuli and can be operantly conditioned to perform behaviors to obtain a food reward. The goal of this experiment is to determine whether the octopus can be operantly conditioned to swim into a box on the side of its tank …
