To increase the knowledge needed to successfully implement the ecosystem-based approach to fishery management, this dissertation investigates important issues within the economics of choice and the economics of displacement. In particular, a discrete choice model of the fishing location decision in the Newport, Oregon bottom trawl groundfish fishery is estimated...
The focus of this study was to examine and record
the physical changes brought about by the breaching of the
Siltcoos Foredune. The origin of the dunes and the physical
processes that operate there must be considered before
effects due to the breach can be studied. A series of field...
The purpose of this study is to examine how members of the Oregon State University polo team negotiate aspects of their social identity. Over the course of the 2011-2012 school year, 15 interviews and 30 hours of observations were conducted. From the data, five overarching themes were identified: inclusion as...
Vibrio bacteria are commonly found in freshwater, marine, and estuarine environments. Members of this genus can exist in commensal relationships with marine animals or as planktonic bacteria, however, they are well known for their roles as pathogens towards humans and animals. In this dissertation, I investigated aspects of host-bacteria relationships...
The ocean fishery is an example of a common property
resource industry. Behavior of commercial fishermen is
determined by a complex set of economic, environmental and
social factors. All of these factors contribute to the
individual fisherman's success.
Fishermen learn to cope with the variability inherent
to their occupation. Two...
Microelectrode array (MEA) dissolved-oxygen (DO) sensors were built and electrochemically tested in a solution of potassium ferricyanide. MEAs are becoming more popular as DO sensors because of their small size and capacity for simultaneous measurements with multiple recording sites. The ability to measure DO with multiple recording sites is useful...
Agonistic behavior among three species of Microtus live-trapped
near Corvallis, Oregon was recorded in order to interpret habitat
segregation by the species in areas of syrnpatry. The method used to
measure agonistic interaction was similar to that of Colvin (1970).
Agonistic behavior was recorded under red light in a neutral...
