Effects of exploitation on life-history characteristics of spiny lobster populations (Panulirus homarus) off Oman

Creator:: Alabdulsalaam, Thabit Z.
Abstract:: The purpose of this research was to examine the effects of fishing on life history parameters of the spiny lobster, Panulirus homarus. The study areas selected had different levels of fishing pressure but relatively similar habitats. The lowest fishing effort was found in Hadbin while the highest fishing effort was...

Ecology and decline of a rare western minnow : the Oregon chub (Oregonichthys crameri)

Creator:: Pearsons, Todd N.
Abstract:: Once historically widespread throughout the Willamette and Umpqua River drainages, the Willamette Oregon chub is now restricted to scattered populations along 15 miles of the Middle Fork of the Willamette River whereas the Umpqua Oregon chub is still widely distributed. The decline in the Willamette drainage was more severe because...

Formation and maintenance of fish assemblages in a high desert Oregon stream

Creator:: Pearsons, Todd N.
Abstract:: Considerable controversy exists about how fish assemblages are organized. I explicitly took fish movement into account while I studied the effects of disturbance, habitat complexity, and predation at different times of the summer to understand the major factors influencing assemblage structure in a high desert Oregon stream. The effects of...

Structure, abundance, and distribution of pelagic zooplankton in a deep, oligotrophic Caldera Lake

Creator:: Karnaugh, Elena N.
Abstract:: From July 1985 to April 1987 the pelagic zooplankton community of Crater Lake, Oregon was studied to determine taxonomic structure, absolute and relative densities, and spatial and temporal distributional patterns. Samples were collected using vertically-towed zooplankton nets. The community structure consisted of two cladoceran and nine rotifer species, which were...

Systematics and ecology of chubs (Gila : Cyprinidae) of the Alvord Basin, Oregon and Nevada

Creator:: Williams, Jack Edward
Abstract:: Seventeen populations of Gila Baird and Girard are identified from the Alvord Basin of southeastern Oregon and northwestern Nevada. Gila in the Alvord Basin occupy a wide range of habitats, including warm springs, cool springs, creeks, reservoirs, and a thermal lake. These populations became isolated in remnant habitats when waters...

Temperature-modulated 7,12-dimethylbenz(a)antheracene carcinogenicity in rainbow trout

Creator:: Zahr, Camille Reda
Abstract:: Temperature influences the incidence of chemically induced cancer in fish, with warmer temperatures being associated with higher cancer incidence. The mechanisms of temperature-modulated chemical carcinogenesis in fish, however, have not been described in detail. Therefore, one primary objective of this study was increased understanding of how temperature-modulated genotoxicity of 7,12-...

Roosevelt elk habitat use in the Oregon Coast Range

Creator:: Witmer, Gary William
Abstract:: Daily and seasonal habitat use by Roosevelt elk was investigated in the Oregon Coast Range on managed, public forestland. Over 3,700 locations of 6 radio-collared cow elk were recorded during 12 consecutive months. Two elk formed part of a north band and 4 elk were part of a south band....

Colony Connectivity of Pacific Coast Double-Crested Cormorants Based on Post-Breeding Dispersal From the Region’s Largest Colony

Creator:: Courtot, Karen N., Roby, Daniel D., Adkins, Jessica Y., Lyons, Donald E., King, D. Tommy, and Larsen, R. Scott
Abstract:: To reduce conflicts with fish resources, other colonial waterbirds, and damage to habitats, double-crested cormorants (Phalacrocorax auritus) are currently controlled (lethally and non-lethally) throughout much of their range. Concerns are growing over the Pacific Coast's largest double-crested cormorant colony at East Sand Island (ESI), Oregon near the mouth of the...

Biology of the Rex sole, Glyptocephalus zachirus Lockington, in waters off Oregon

Creator:: Hosie, Michael J.
Abstract:: Data are presented on the life history and population dynamics of rex sole (Glyptocephalus zachirus Lockington) collected from Oregon waters between September 1969 and October 1973. Length-weight relationships vary little between sexes or with time of year. Otolith annuli form primarily from January through May and were used for age...

Evaluation of baits and baiting techniques for Belding's ground squirrels

Creator:: Sullins, George Lamont
Abstract:: Quantitative data concerning bait preference and bait application were collected for Belding's ground squirrels (Spermophilus beldingi) during February-July 1975. Bait materials tested for preference were crimped oats, oatgroats, whole wheat, barley, rolled wheat, rye, chopped lettuce, chopped apple, oatgroats + Rhodamine B dye, oatgroats + starch paste, oatgroats + Rhoplex...
