Juvenile Rockfish (Sebastes spp.) Community Composition and Habitat use of Yaquina Bay, Oregon

Creator:: Lindsley, Amy J.
Abstract:: Estuaries, which provide viable habitat for a plethora of fish and invertebrate species, are being increasingly impacted by anthropogenic and natural forces. Estuaries are important nursery habitat for young-of-the-year (YOY) Pacific rockfish (Sebastes spp.).

The dynamics of an isolated population of Acartia tonsa Dana (Copepoda) in Yaquina Bay, Oregon

Creator:: Johnson, John Kenneth
Abstract:: In the upper estuary of Yaquina Bay, Oregon, there is an annual population explosion of Acartia tonsa, (Dana) a calanoid copepod, during the months of July, August and September, followed by a rapid decline to virtual extinction in November. The restricted estuarine distribution affords an excellent opportunity to study the...

The ghost shrimp, Callianassa californiensis Dana, 1854, in Yaquina Bay, Oregon

Creator:: McCrow, Lynne Tucker
Abstract:: The life cycle of Callianassa californiensis Dana, 1854, was studied in the tidal estuary, Yaquina Bay, Oregon. At this latitude it is largely restricted to intertidal sandy mudflats under predominately marine influence. Salinity and temperature appear to determine its distribution to a greater extent than does sediment type. Vertical movement...

Movement and abundance of lingcod (Ophiodon elongatus) in Yaquina Bay Estuary, Oregon: evidence for essential habitat designation

Creator:: Schwager, Tad W.
Abstract:: Lingcod (Ophiodon elongatus) are known to utilize certain estuaries along the Pacific coast of the United States, but the importance of these habitats to the coast-wide population is not well understood. In this study, general patterns of estuarine habitat use were assessed by tracking the movement of sub-adult and adult...

Direct effects and tradeoffs affect vegetative growth and sexual reproduction in an invasive seagrass experiencing different disturbance regimes

Abstract:: Disturbance has both direct and indirect ramifications that can influence species abundance, distribution, and ultimately the diversity found within a community. As a result, we might expect disturbance to play a particularly important role in the ability of non-native species to proliferate outside of their native range. In practice, disturbance...

Use of extractable lipofuscin as an age biomarker to determine age structure of ghost shrimp (Neotrypaea californiensis) populations in west coast estuaries

Creator:: Cassidy, Katelyn M.
Abstract:: Determining age in crustaceans is inherently imprecise because they molt periodically and do not retain hard structures throughout their lifespan. Morphological measurements, such as carapace length, are often used to estimate age because methods for direct ageing do not exist. However, variability in individual growth rate and molt frequency can...
