Research Program: The status of aquatic and terrestrial resources in the diverse, large, and dynamic landscapes of the interior west offer unique challenges. Aquatic and terrestrial ecosystems in this region share a management history that has extensively altered both. For example, 45 of 88 native fish taxa within the Interior Columbia River basin are considered sensitive or of special concern, 14 are federally listed under the Endangered Species Act, and more are proposed for listing. A growing human population and economy are expanding demands on limited resources and increasing challenges for biologists and land managers. Simplification of habitat, initiatives for the restoration of forest health, concerns about wildfire, and a changing climate have precipitated debate about conservation and restoration approaches. By advancing understanding of ecological processes and functions, my research will play a central role in helping strategically guide the complex and challenging management of sensitive native species and in realizing opportunities to conserve and restore functional aquatic and terrestrial ecosystems.
Within this context, I conduct a broad range of studies over multiple spatial and temporal scales to improve our understanding of aquatic species and the ecosystems they depend upon. Research topics include:
A.) Patterns of species and life stages
- There is a need to Integrate Disciplines and Broaden the Scales at which we investigate the physical and biological processes influencing aquatic habitat and the distribution, diversity, and persistence of fish.
- New knowledge is required to describe Temporal and Spatial Habitat Requirements for poorly understood life stages of native fishes.
- As Landscape Analyses assume a more central role in ecosystem management, it is critical to understand the Influence of Landscape Features and Processes on the Distribution of Critical Fish Habitats.
- Improved analytical frameworks and guidelines are essential for interpretations of Species Status and Occurrence at large scales.
B.) Structure of populations
- Patterns in the distribution and spatial structure of populations may be important to their persistence in stochastic environments. There is a need to understand how Habitat Geometry and Spatial Structuring influence fish population dynamics and persistence.
- Metapopulation Theory suggests that dispersal and recolonization will influence the dynamics and persistence of populations. Empirical evidence is limited, however, and additional understanding of salmonid dispersal and recolonization mechanisms is needed.
C.) Sampling protocols
- Biologists and managers need reliable methods to assess the Status of fish populations, to monitor Population Responses to Management Activities, and to measure Fish Responses to Temporal and Spatial Changes in habitat.
D.) Climate affects
- There is a critical need to understand the Effects of a Warming Climate on the phenology, distribution, abundance, and persistence of native western fishes.
- The biology, habitat utilization, and critical habitat requirements of sensitive native fishes.
- Landscape level models of species distribution and status.
- Effects of fine sediments on salmonid spawning and incubation.
- Methods for assessing the effects of watershed disturbance on species occurrence.
- Methods for monitoring characteristics of spawning substrates.
- The influence of landscape features on critical habitats.
- The relevance of spatial structure to the persistence of aquatic species.
- Demographic and genetic structuring of populations.
- The importance of metapopulation processes to population persistence.
- Bias and precision of sampling methods and development of improved sampling protocols.
- Effects of angling regulations on native trout populations.
As one of three scientists with the Aquatic Science Team and the Science Integration Team for the Interior Columbia River Basin Ecosystem Management Project, we helped developed an assessment of the distribution, status, and ecology of native fishes in the Interior Columbia River basin and portions of the Klamath River and Great basins, an area encompassing 58.3 million ha and portions of six western states. The aquatic resource report for the ICBEMP represents a contribution to fisheries science and management of regional and national significance. The aquatic assessment of native fishes represents the most comprehensive and spatially explicit evaluation ever attempted in the Intermountain and Pacific Northwest.
