Aging Giant Pacific Octopus using Beaks and Stylets for Better Stock Structure Assessment

Creator:: Yarbrough, Ashley
Abstract:: Despite being a highly charismatic and frequently exhibited organism, Giant Pacific Octopus (Enteroctopus dofleini) population dynamics are poorly understood. Basic monitoring data for this species is limited to bycatch and stomach contents of other fisheries species. An essential step to a better estimation of population size and productivity is to...

Identification and systematics of larvae of Artedius, Clinocottus, and Oligocottus (Scorpaeniformes:Cottidae)

Creator:: Washington, Betsy B.
Abstract:: Complete, identified, developmental series of larval cottids Artedius fenestralis, A. creaseri, A. meanyi, Oligocottus snyderi, Clinocottus embryum, and C. globiceps are described for the first time. In addition, redescriptions of four species, Artedius harringtoni, A. lateralis, Oligocottus maculosus, and Clinocottus acuticeps are included that provide new and comparative information on...
Resource Type:: Masters Thesis
Full Text:: Clinocottus and Oligocottus are very closely related; however, each genus appears to be monophyletic. Larvae

A review of the deep water Liparidae from the coast of Oregon and adjacent waters

Creator:: Stein, David L.
Abstract:: Descriptions and distributions are given of 28 species of Liparidae occurring or possibly occurring below 200 m between San Francisco and northern Vancouver Island, with keys for their identifications. Nine genera are included: Careproctus, Elassodiscus, Lipariscus, Nectoliparis, Rhinoliparis, Acantholiparis, Paraliparis, and two new genera are described, Odontoliparis and Osteodiscus. Eight...
Resource Type:: Masters Thesis
Full Text:: species from 2200-3600 m. Morphological characters are related to the depth distributions of the species

Life history patterns of two allopatric clupeids : Atlantic menhaden (Brevoortia tyrannus) and gulf menhaden (B. patronus)

Creator:: Powell, Allyn B.
Abstract:: Atlantic menhaden, compared to gulf menhaden, exhibit a life history pattern that appears to be adapted to a more unpredictable reproductive environment. From experiments on laboratory-reared eggs and larvae, Atlantic menhaden have larger eggs with larger yolk volume. They are larger at hatching, utilize their yolk faster, begin feeding at...

Systematics, variation, distribution, and biology of lampreys of the genus Lampetra in Oregon

Creator:: Kan, Ting Tien
Abstract:: Based on the number of velar tentacles and the form of longitudinal lingual laminae found in Lampetra (Entosphenus) t. tridentata and its closely related forms, the taxon Entosphenus should not be considered as a genus as commonly adopted, but, along with the taxa Lethenteron and Lampetra, should be regarded as...

Implications of cougar prey selection and demography on population dynamics of elk in northeast Oregon

Creator:: Clark, Darren A.
Abstract:: Mule deer (Odocoileus hemionus hemionus) and Rocky Mountain elk (Cervus canadensis nelsoni; hereafter elk) populations in northeast Oregon have declined in the past 10 to 20 years. Concurrent with these declines, cougar (Puma concolor) populations have apparently increased, leading to speculation that predation by cougars may be responsible for declining...
