Release-recapture models for migration juvenile and adult salmon in the Columbia and Snake Rivers using PIT tag and radiotelemetry data
Release-recapture models for two types of tagging data from migrating salmonids in the Columbia and Snake rivers are presented. The first model uses both juvenile and adult PIT-tag data to analyze the seaward and spawning migrations through the hydrosystem. This branching model accommodates transported smolts, known removals, ...
Multi-criteria assessment of ecological process models using pareto optimization
Assessment is the essential step in using an ecological process model as a heuristic for investigating hypotheses. Assessment investigates the model's capacity to adequately simulate the phenomenon, as represented by selected criteria. A model's inability to satisfy all assessment criteria simultaneously reveals inadequacies ...
Monte Carlo methods for inference in population genetic models
This dissertation describes novel applications of Monte Carlo and Markov chain Monte Carlo (MCMC) techniques to statistical inference in problems from the field of conservation genetics. The inference problems are motivated by issues arising in the conservation and management of trout and salmon. The first half of the thesis ...
Multi-objective optimization for ecological model assessment and theory development
The motivation for building ecological process models is to synthesize observations and explore hypotheses for system functions. In the course of ecological research it is common to choose a trajectory for a research program in order to explain an observed phenomenon, often at the exclusion of other possible explanations. In ...
The dynamics and effects of bacterial kidney disease in Snake River spring Chinook salmon (Oncorhynchus tshawytscha)
Bacterial kidney disease (BKD) is endemic in Snake River spring chinook salmon (Oncorhynchus tshawytscha) stocks of both wild and hatchery origin, and may be partially responsible for their poor returns in recent years. BKD is particularly difficult to control due to the chronic nature of the disease. Renibacterium salmoninarum, ...
