New insights on an old topic : understanding the effects of forest harvest on trout in the context of climate

Creator:

Penaluna, Brooke E.

Abstract:

Studies of the effects of forest harvest on streams and fish have a long history in the Pacific Northwest. Results of this work have prompted development of new forest harvest practices that are more protective of these resources, but the effectiveness of these new practices has not been fully evaluated....

Ecological relationships among western Ephemerellidae : growth, life cycles, food habits, and habitat relationships

Creator:

Hawkins, Charles Patrick

Abstract:

The purpose of this study was to describe the life cycles, feeding ecology, and habitat use of western species in the mayfly family Ephemerellidae. Data were used to compare the ecological relationships and strategies among species and to examine patterns of adaptive radiation within the family. Data were further used...

Succession and stability in two rocky intertidal communities on the central Oregon coast

Creator:

Farrell, Terence M.

Abstract:

The stability of a limpet-dominated community was assessed in a experiment in which an consumer was temporarily removed. Compared to unmanipulated plots, the limpet-exclusion plots developed greater algal abundance and altered species composition of both algae and barnacles. The community was not perturbed beyond its capacity to recover, since the...

Effects of sampling design, estimators, and variability on groundfish management in Oregon

Creator:

Crone, Paul R. Jr

Abstract:

Sampling error associated with estimates of species composition and age composition of commercial groundfish landings in Oregon from 1989 to 1991 is documented to evaluate the impact of variable landing data on fisheries management and monitoring programs. The statistical reliability and bias associated with two multistage sampling designs are investigated...
