Practical Solutions To The Invasion Of Lionfish In Utila, Honduras: Science, Education, Food, And Jewelry, Carolyn Corley
Practical Solutions To The Invasion Of Lionfish In Utila, Honduras: Science, Education, Food, And Jewelry, Carolyn Corley
Undergraduate Honors Theses
Lionfish (Pterois sp.) are invasive species capable of devastating coral reef ecosystems due to their lack of predators, large appetites, generalist diet, high fecundity, and rapid spawning rates. As lionfish have expanded their distribution across the Caribbean, many conservation groups have taken it upon themselves to systematically remove these predators from environments where they are threatening native species. However, few have involved the community the way I observed while interning with the Whale Shark and Oceanic Research Center in Utila, Honduras. Protecting coral reefs is extremely important, especially in small communities like Utila, where the majority of people’s …
Life History Of Two Goatfishes In Hawaii And Alternative Methodologies In Life History Research, Duncan Campbell
Life History Of Two Goatfishes In Hawaii And Alternative Methodologies In Life History Research, Duncan Campbell
Undergraduate Honors Theses
Data-driven management of fisheries requires information on the life history of the species being managed. I provide new information on the life histories of two goatfish species in Hawaiʻi, Parupeneus insularis and Parupeneus cyclostomus. Fish were collected using spearfishing from the reefs of Oʻahu between 2020 and 2023. Macroscopic and microscopic methods of assigning maturity and reproductive stage were used to estimate size at maturity and seasonality. Parapeneus insularis females are estimated to reach 50% maturity at 188 mm fork length (95% CI: 177mm, 197mm), and 95% maturity at 245 mm FL (95% CI: 226mm, 287mm). P. cyclostomus females reach …
Fecal Pellet Production By North Atlantic Zooplankton, Michael Gibson
Fecal Pellet Production By North Atlantic Zooplankton, Michael Gibson
Undergraduate Honors Theses
Fecal pellet carbon (FPC) production by zooplankton is a significant component of the ocean’s biological carbon pump: the suite of biological processes that mediate export of carbon to the deep ocean, ultimately leading to the sequestration of atmospheric carbon dioxide in the ocean. In this study, mesozooplankton (zooplankton 0.2 mm to ~2 cm) were collected from the epipelagic zone in the temperate North Atlantic Ocean during day and night in May 2021. Zooplankton were live separated into five size fractions and incubated on board ship in natural surface seawater to measure fecal pellet production rate of the mixed mesozooplankton community. …
Porifera: Biology And Medicinal Properties, Emma L. Rayfield
Porifera: Biology And Medicinal Properties, Emma L. Rayfield
Undergraduate Honors Theses
The focus of this thesis is the possibility of oceanic medicine through understanding the general biology of poriferans, their symbionts, medicinal properties, and how we could harvest sponges conservatively. It was necessary to understand the basic biology of poriferans regarding their structures, differences in their classes, and how they obtain nutrition, develop, and reproduce. The ecology of the poriferans was also researched including their larval and sessile stages and how their environment determines where they settle. Additionally, ecology was examined including how poriferans interact with symbionts and other organisms. This then was utilized to seek whether poriferans had useful medical …
