Contextual systems description of an Oregon coastal watershed

Creator:: Goetze, Brigitte
Abstract:: Many resource management controversies indicate disagreement about the possible intended and unintended effects of management actions on ecosystems. Researchers have documented a variety of negative effects on specific ecosystems, e. g. the degradation of salmonid habitat due to mass wasting (Hagans et al. 1986). While the effects of some management...

Classification of Icelandic watersheds and rivers to explain life history strategies of Atlantic salmon

Creator:: Gudjonsson, Sigurdur
Abstract:: A hierarchical classification system of Iceland's watersheds and rivers is presented. The classification is based on Iceland's substrate, climate, water, biota, and human cultural influences. The geological formations of Iceland are very different in character depending on their age and formation history. Three major types of formations occur: Tertiary, Plio-Pleistocene,...

Toward a general theory of exploitation of fish populations

Creator:: Liss, William J.
Abstract:: A possible form of a theory of exploitation of fish populations was examined. The exploitation theory was derived from a theory of community dynamics that represents the interactions between populations in a biological community with complex interrelated systems of isoclines on phase planes. The isocline systems are deduced, with a...

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...

Life history strategies and tactics of striped bass (Morone saxatilis) Walbaum

Creator:: Eldridge, Maxwell B.
Abstract:: Traditional approaches to research and management of striped bass have tended to be mechanistic, numerically oriented, and based on limited life history information. In the study presented here, comprehensive conceptual perspective was used in a multivariate study of life history and evolutionary adaptation of 10 striped bass populations representing the...

Geomorphic influences on habitat formation, distribution, and development and the classification of upland coastal Oregon streams

Creator:: Hurley, Michael D.
Abstract:: A framework is presented for a more causal explanation and ordering of stream characteristics than traditional means have used. Patterns of stream habitat distribution are related to particular characteristics of the geomorphology of watersheds. Variability in stream characteristics can be explained by the spatial distribution of properties of the watershed...

Effects of perturbation on community structure and organization in aquatic microcosms

Creator:: Finger, Susan Everett
Abstract:: Aquatic communities consisting of guppies, amphipods, copepods, snails, nematodes, rotifers, protozoans, euglenoid flagellates, and other microorganisms were established in sixteen laboratory microcosms. Guppies were exploited at four different levels (0 percent, 10 percent, 20 percent, and 40 percent of the population biomass) with four communities at each level of exploitation....
