Phytoplankton Community Dynamics In The Northern California Current System, Kristin Forgrave
Phytoplankton Community Dynamics In The Northern California Current System, Kristin Forgrave
Student Research Symposium
The Northern California Current system is a productive coastal ecosystem that encompasses a variety of temporal and spatial features. The photosynthetic microbial community plays a crucial role in supporting the rich ecosystem and economically important fisheries. My research integrates data across distance and two years to investigate the community composition of two major phytoplankton groups in this system: picocyanobacteria and picoeukaryotes. The abundances and sizes of the phytoplankton were measured using flow cytometry. Picoeukaryotes were found to be present at similar concentrations in both summer and winter. Abundances of both cell types were comparable in the winter, but picocyanobacteria were …
Non-Native Mangroves Of Moloka'i, Hawai'i: A Socio-Ecological Analysis, Casey Lewis
Non-Native Mangroves Of Moloka'i, Hawai'i: A Socio-Ecological Analysis, Casey Lewis
Student Research Symposium
Invasive species are recognized as a leading threat to ecosystems and their management is expensive, time consuming, and labor intensive. Therefore, it is important to review both benefits and detriments of the species to inform appropriate management decisions. Red mangrove was introduced to Moloka'i, Hawaii in 1902 to mitigate the effects of soil erosion and has since spread along the coast and to adjacent islands creating novel habitat. This study assessed both biological services and social attitudes towards Moloka'i's non-native mangroves to provide a comprehensive evaluation of the species. Zooplankton community structure was examined in mangrove and non-mangrove sites and …
