Design of an apparatus with controlled rates of temperature change for use in cold tolerance tests of conifers

Creator:: Wessell, William James
Abstract:: An apparatus was designed to permit freezing tests of needles and other tissue parts from coniferous trees under controlled rates of temperature change with time. The design is based on the principle of a balanced system of refrigeration demand and heat input to achieve a steady temperature state. The apparatus...

Biodiversity in managed forests of western Oregon : species assemblages in leave islands, thinned, and unthinned forests

Creator:: Wessell, Stephanie J.
Abstract:: Both leave islands, or green tree retention clusters, and thinning prescriptions have been proposed as alternative silvicultural strategies designed to sustain the structural and biological diversity of managed forests. However, the relationship of the physical structure of leave islands and thinned forests to their associated microclimates, flora, and fauna remain...

Range-use estimation and encounter probability for juvenile Steller sea lions (Eumetopias jubatus) in the Prince William Sound-Kenai Fjords region of Alaska

Creator:: Meck, Stephen R.
Abstract:: Range, areas of concentrated activity, and dispersal characteristics for juvenile Steller sea lions Eumetopias jubatus in the endangered western population (west of 144° W in the Gulf of Alaska) are poorly understood. This study quantified space use by analyzing post-release telemetric tracking data from satellite transmitters externally attached to n...

Vegetation ecology of Fraxinus latifolia communities in William L. Finley National Wildlife Refuge, Oregon

Creator:: Heinitz, Eric Fajen
Abstract:: Composition and structure of Oregon ash (Fraxinus latifolia) woodlands in the William L. Finley National Wildlife Refuge, Oregon are described. Twenty stands dominated by Fraxinus latifolia were sampled with 500 m2 circular macroplots in which floristic microplot data were collected for plant community synthesis. Plant communities were identified by computer-assisted...

Boating in Alaska's Prince William Sound : modeling and assessment of recreational use

Creator:: Wolfe, Phillip E.
Abstract:: This study measures the recreational boating use in Prince William Sound, Alaska. Improved access conditions to the Sound over the last decade coupled with a statewide increase in outdoor recreation participation among both resident and out of state tourists have made the Sound a focal point for recreational boating in...

A georeferenced digital image analysis of micro-topographic patterns within the Willamette Floodplain Research Natural Area, W. L. Finley National Wildlife Refuge

Creator:: Anderson, Karen L.
Abstract:: The present day vegetation pattern of the Willamette Valley is a result of a long past of human alteration of the landscape. Beginning with aboriginal burning of the grasslands to present day land uses, the vegetation of the valley has been affected by anthropogenic activity. Wet prairie is a vanishing...

Distribution of Pacific herring spawn in Yaquina Bay, Oregon, and observations on mortality through hatching

Creator:: Steinfeld, James David
Abstract:: Studies were conducted during late winter and spring of 1970 to establish the extent of spawning of Pacific herring (Clupea harengus pallasi Valenciennes) in the Yaquina estuary, and to define the degree of egg mortality on certain substrates. Routine surveillance of the north shore of the estuary provided information on...

Relationships between air quality and thermal structure of the lower atmosphere at Salem, Oregon

Creator:: McElroy, James L.
Abstract:: The examination in some detail of the relationships between air quality and the thermal structure of the lowest layers of the atmosphere constituted the primary objective of this thesis. Data for the study were assembled during April-June 1965 at the U.S. Weather Bureau Station, McNary Field, Salem, Oregon. The measures...

Architecture, size, and reproduction in plants : a pollination study of Mertensia ciliata (James) G. Don

Creator:: Geber, Monica
Abstract:: I experimentally test the hypothesis that the potential for selfing increases with plant size in Mertensia ciliata (Boraginaceae), a self-compatible, profusely-flowering perennial. This follows from the premises that 1) pollen dispersal by pollinators between flowers is limited, and 2) individual pollinators, in this study bumblebees, will visit more flowers per...
