The swimming response of the Sacconereis stage of Autolytus varius to changes in hydrostatic pressure

Creator:: Smith, Randall William
Abstract:: The syllid polychaete Autolytus varius reproduces in the spring and early summer in Yaquina Bay, Oregon, The fertilized female epitokes, or Sacconereis, carry the developing eggs and larvae in a ventral sac until the larvae are ready to be released; incubation lasts 14 to 18 days in the laboratory, The...

Metabolic adjustment to temperature in Strongylocentrotus purpuratus (Stimpson)

Creator:: Ulbricht, Richard Jules
Abstract:: The metabolism of Strongylocentrotus purpuratus (Stimpson) was investigated at several levels of urchin organization. Some experiments were performed with tissues from recently collected (acclimatized) urchins, Other experiments were performed with tissues from urchins held at one of two temperatures (acclimated) for 30 days. Body-component oxygen consumption was measured for bodywall,...

The role of oxygen and other environmental variables on survivorship, abundance, and community structure of invertebrate meroplankton of Oregon nearshore coastal waters

Creator:: Eerkes-Medrano, Dafne I.
Abstract:: The high productivity of Eastern Boundary Upwelling Ecosystems (EBUE), some of the most productive ecosystems in the globe, is attributed to the nutrient rich waters brought up through upwelling. Climate change scenarios for coastal upwelling systems, predict an intensification of coastal upwelling winds. Associated with intensification in upwelling are biogeochemical...

Changing Climate, Changing Contexts : Variation in Rocky Intertidal Predator-prey Interactions Seen Through an Environmental Stress Framework

Creator:: Cerny-Chipman, Elizabeth B.
Abstract:: The multifaceted role of the environment in regulating the structure and dynamics of biological communities has long fascinated ecologists and motivated much debate and research. Now, in a time of accelerated global changes due to human impacts, the need to understand how the environment shapes communities has gained new urgency....

Temperature stress, gene expression, and innate immunity at the onset of cnidarian-dinoflagellate symbiosis

Creator:: Schnitzler, Christine E.
Abstract:: The intracellular mutualism between cnidarians and photosynthetic dinoflagellates (genus Symbiodinium) is responsible for the physical and trophic structure of diverse coral reef ecosystems. This relationship, based on nutrient exchange, allows for high productivity in tropical waters, which are generally nutrient-poor environments. Numerous environmental stressors currently threaten the health of corals,...

Fine structure and histochemistry of the cuticle of the cercaria of Acanthatrium oregonense (Macy)

Creator:: Inhelder, Carol Marie
Abstract:: The cuticle of the cercaria of Acanthatrium oregonense was studied by means of electron microscopy and histochemistry. The integument of this cercaria has a definite ultrastructure which varies in different regions of the body. The body cuticle is a syncytium containing vesicles and mitochondria. It is bounded externally by a...

Behavior and Ecological Effects of Invasive Lionfish on Atlantic Coral Reefs and Seagrass Beds

Creator:: Benkwitt, Cassandra E.
Abstract:: Although only a minority of introduced species become established and have noticeable consequences in their new communities, some can displace native species, alter food webs, and cause local extinctions. Studying these invasive species can provide new insights into basic ecological questions as well as inform management strategies. Pacific lionfish (Pterois...

Fine structure and function of the neck organ in the brine shrimp Artemia salina nauplius

Creator:: Hootman, Seth R.
Abstract:: The morphology of the dorsal neck organ of the brine shrimp Artemia salina nauplius was investigated to determine its role(s) during larval development. Light and scanning electron microscopic studies show that the neck organ is present in the pre-nauplius larval forms as early as 12 hours after hydration of the...
