Photoperiod and the timing of pupping in the Pacific harbor seal (Phoca vitulina richardsi) with notes on reproduction in northern fur seals and Dall porpoises

Creator:: Temte, Jonathan L.
Abstract:: Birth and pupping season records of Pacific harbor seals (Phoca vitulina richardsi) were used in an analysis of photoperiod effect on the timing of birth in this species. Dates and latitudes of births were converted into photoperiods using a photoperiod equation. Sequential dates from parturition were converted into photoperiods and...

A model of forest nitrogen cycling to assess the effects of management intensity on long-term productivity in Douglas-fir forests of the Pacific Northwest

Creator:: Krzak, Joan
Abstract:: The objective of this study was to assess the effects of forest management intensity on long-term productivity of Pacific Northwest Douglas-fir forests. The components of management intensity included rotation length, timber utilization standard (whole tree or bole only), method of slash treatment (remove/burn or leave) and fertilization practice (urea nitrogen...

"Pushing for the Highline" : The Diffusion of Innovations in the Oregon Otter Trawl Fishery

Creator:: Stephenson, Garry Owen
Abstract:: Implementation of. the Fishery Conservation and Management Act of 1976 affords opportunities for fishery expansion and economic development in the Oregon otter trawl fishery. The changes stimulated by the Act should occur, according to social science theorists, by the diffusion of innovations from innovative fishermen to less innovative fishermen, with...

Population and community ecology of the red alga Rhodomela larix (Turner) C. Agardh, on the central Oregon coast

Creator:: D'Antonio, Carla Marie, 1956-
Abstract:: Aspects of the life history and ecology of the intertidal turf-forming alga Rhodomela larix (Turner) C. Agardh were examined over a two year period at several sites on the Oregon coast. Rhodomela occurred over a broad tidal range and exhibited different growth and morphology characteristics with respect to tidal height....

Dry coniferous forests in the Western Oregon Cascades

Creator:: Means, Joseph E.
Abstract:: Pseudotsuga menziesii dominates the forests of the Pacific Northwest. But though it is dominat, Tsuaa heteroohylla or Abies amabilis is usually climax. Many researchers have studied Pseudotsuga on the widespread mesic sites where it is seral, but few have examined the relatively rare ecosystems in which Pseudotsuga or its associate...
