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 …

The Population Genetics Of Morro Bay Eelgrass (Zostera Marina), Julia Gardner Harencar
Master's Theses
Seagrass populations are in decline worldwide. Zostera marina (eelgrass), one of California’s native seagrasses, is no exception to this trend. In the last 8 years, Morro Bay, California has lost 95% of its eelgrass. Eelgrass is an ecosystem engineer, providing important ecosystem services such as sediment stabilization, nutrient cycling, and nursery habitats for fish. The failure of recent restoration efforts necessitates a better understanding of the causes of eelgrass decline in this estuary. Previous research on eelgrass in California has demonstrated a link between population genetic diversity and eelgrass bed health, ecosystem functioning, and resilience to disturbance and extreme climatic …
