Algal Wrack Community Composition And Succession On A Sandy Beach In San Diego, Ca, Marisol Palomares
Theses
Sandy beaches are high-energy impact zones that produce little to no organic material. Much of the organic matter on beaches is washed up on shore in the form of algal wrack, providing a vital source of nutrients, food, and habitat for a variety of organisms on the sandy beach. Over time wrack will decay and decompose, releasing nutrients including nitrogen and phosphorus, which are consumed by benthic microalgae and bacteria. The type of wrack and geomorphology of the beach environments affect decomposition, which in turn supports a variety of different wrack associated macrofaunal communities. Different species of algal wrack will …
The Effect Of Phytoplankton Properties On The Ingestion Of Marine Snow By Calanus Pacificus, Grace Cawley
The Effect Of Phytoplankton Properties On The Ingestion Of Marine Snow By Calanus Pacificus, Grace Cawley
Theses
The aggregation of phytoplankton into marine snow provides a mechanism by which smaller particles can coagulate to form larger particles, which can be consumed at various depths or readily transported to the deep ocean and sequestered from the atmosphere on time scales of a thousand years or more. Zooplankton interacting with these large carbon-rich aggregates can obtain nutrition in environments where the phytoplankton size spectrum is small and not directly available, enhancing the possibility of obtaining adequate nutrition in environments dominated by small cells. In addition, interactions between zooplankton and marine snow can result in fragmentation, thus affecting the particle …

Nearshore Vertical Distribution Of Barnacle Cyprids: Temporal Patterns And Hydrographic Variability, Gabriela Yamhure
Theses
Most benthic organisms living in the intertidal zone have planktonic larvae that reside temporarily in the water column before settling in their adult habitats. Larvae aggregate in offshore larval pools, and transport horizontally and vertically in the water to remain in the nearshore and during their pelagic life. While some horizontal transport of larvae can be attributed to advection, behavioral responses, like vertical swimming and buoyancy control, allow larvae to position themselves at depths where flow direction can be exploited. Thus, knowledge on how vertical larval distribution relates to physical processes can be fundamental to better understand larval transport. These …
