Biomass Estimation Of Marine Biofilms On Plastic Surfaces, Kian Banihashemi, Fernando Javier Gil
Biomass Estimation Of Marine Biofilms On Plastic Surfaces, Kian Banihashemi, Fernando Javier Gil
Biological Sciences
Plastics have become a major source of marine pollution, which threatens food safety and quality, human health, and marine ecosystems. Due to the drastic negative effects of plastics in a marine environment, alternative biodegradable plastics are being generated that are more eco-friendly and have less environmental impact. Though some of these plastics are known to biodegrade, the process of degradation for bioplastics has not been heavily studied in a marine environment. This pilot project sought to both quantify the process of biodegradation and compare across different methods for effectiveness of biomass estimation, which serves as an indicator of biodegradation. Plastics …
Phytoplankton Community Response To Changing Environmental Conditions Across Two Central California Sites, Nicholas Soares
Phytoplankton Community Response To Changing Environmental Conditions Across Two Central California Sites, Nicholas Soares
Biological Sciences
Understanding the role that changing environmental conditions play in altering phytoplankton abundance and community composition, and in turn ecosystem structure and function, will be increasingly important for the sustainable use and management of ocean resources in a changing climate. Characterizing change in nearshore ecosystems requires long-term studies with a broad spatial extent, with most studies sacrificing spatial extent for temporal duration. However, phytoplankton and ecosystem response can vary substantially over small spatial scales due to local oceanographic forcing and anthropogenic influence, making the application of long-term data from one site to another in the same geographic vicinity potentially challenging. In …
Comparative Effects Of Chemical And Physical Sunscreen On Fertilization Of Purple Sea Urchins (Strongylocentrotus Purpuratus), Marilla Lippert, Maurice Codespoti Goodman, Nikki Adams
Comparative Effects Of Chemical And Physical Sunscreen On Fertilization Of Purple Sea Urchins (Strongylocentrotus Purpuratus), Marilla Lippert, Maurice Codespoti Goodman, Nikki Adams
Biological Sciences
Organic compound-based “chemical” sunscreens dominate the commercial sunscreen market, but recent research has revealed the ingredients of these products are detrimental to the health of marine organisms. This revelation has led to increased popularity of mineral-based “physical” sunscreens, primarily containing zinc-oxide (ZnO), as environmentally safe alternatives. While they are marketed as environmentally safe, these claims are largely untested, and it is important to consider potential effects of ZnO-based sunscreens on the development of marine organisms. Though Zn is a necessary micronutrient in the ocean, excess Zn is released into marine environments from anthropogenic sources has negative effects on marine life. …
Understanding The Transition From Benthic Egg To Dispersive Larvae: Observations On The Intra-Capsular Growth And Development Of A Marine Snail (Kelletia Kelletii), Megan N. Wilson
Biological Sciences
It has long been understood that the larval life stage is responsible for the dispersion of many marine organisms across their biogeographic range. Such organisms have a bipartite life cycle, existing in the water column and subject to oceanographic processes as planktonic larvae before settling to suitable habitat along the benthos where they grow and mature. Previous studies have demonstrated that larval growth rate and behavior in the water column can alter larval position in relation to ocean currents and affects their dispersal pathway. However, there is a paucity of information regarding the growth rate of the earliest larval stage …
