Behavior and Functional Morphology of Respiration in the Basket Star, Gorgonocephalus eucnemis and Two Brittle Stars in the Genus Ophiothrix

Hainey, MacKenna (University of Oregon, 2019-01-11)

Gorgonocephalus eucnemis, Ophiothrix suensonii and Ophiothrix spiculata are aerobic Echinoderms. Previous observations on the anatomy of these two genera state five pairs of radial shields and genital plates are responsible ...
Differences in the density of aboral tridentate pedicellariae of Strongylocentrotus purpuratus from two different sites

Baki, Zane (University of Oregon, 2023)

The purple urchin (Strongylocentrotus purpuratus) is a prominent grazer on the Oregon coast that has helped create and maintain urchin barrens by preventing the re-establishment and growth of new kelp. Urchins have 4 ...
Evolution of Developmental Pattern and Larval Form in the Ophiuroids of Oregon and Beyond

Nakata, Nicole (University of Oregon, 2024-03-25)

Despite the ubiquity and known impacts of transitions in developmental pattern in marine invertebrates, many taxa have been insufficiently analyzed. In Chapter II, I report the effects of larval feeding in an undescribed ...
Larval Supply, Settlement, and Post-Settlement Performance as Determinants of the Spatial Distribution of Olympia Oysters (Ostrea lurida) in Coos Bay, OR

Rimler, Rose (University of Oregon, 2014-06-17)

The Olympia oyster, Ostrea lurida. was overharvested in the early 20th century and is now the focus of restoration efforts in estuaries along the west coast of North America. These efforts would be aided by a better ...
Settlement and Growth of the Marine Bryozoan Schizoporella japonica, and Epifaunal Development in the South Slough Estuary

Treibergs, Kira (University of Oregon, 2012)

The pre-metamorphic behaviors and settlement preferences of larvae can have significant effects on the success of adult invertebrates. This study describes various aspects of pre-metamorphic and post-metamorphic life ...
Swimming Kinematics and Thoracic Appendage Morphology in Cyprids of Balanus glandula

Lamont, Eleanor (University of Oregon, 2018-04-10)

As the final larval stage before settlement, barnacle cyprids swim with six pairs of thoracic appendages used to maintain orientation, change direction, and swim against downwelling currents. This thesis examines thoracic ...
