Page 12been a team collaboration and what I consider one of the biggest contributions of my research program.This project was initiated by Michael Feller and further developed into a broader study when I joined thefaculty. Other teams that I have worked with include a Variable Retention project lead byWeyerhaeuser and an attempt to develop a working team for the riparian studies in the Cariboo Region.There are four interwoven thematic areas in my research program.UPopulation, community and ecosystem processes in streams, riparian areas, and wetlandsU: Many of ourprojects involve experiments to determine the processes and the controls on those processes withincommunities. In particular, the scaling of various structures and processing, and their non-additiveinteractions (complex effects) are critical to an understanding of how these natural or modified systemsare organized. The primary biological components I have worked on include invertebrates, amphibians,fish, algae, bacteria, and small mammals.UOrganic carbon dynamics in small streamsU: Small streams depend on a variety of sources of fixedcarbon, and as donor-controlled pathways primarily from terrestrial environments, provide a stronglinkage from watersheds to streams. Modification of riparian vegetation through forest management orsuccession can have a large effect on the carbon sources.UApplied studies of the effects of land-use (e.g. forestry), contaminants, and other disturbance on streamsU:As an applied scientist many of our studies address how various alterations from land-use affect naturalsystems. Various studies have been descriptive and experimental studies of tailed frogs, Pacific giantsalamanders, woodland stream biodiversity, heavy metals, acid mine drainage, biomonitoring, andcommunity structure of the lower Fraser River. These studies complement my overall researchprogram by considering various insults to communities and populations as a kind of probe withincommunities.UEndangered and threatened species associated with streams and riparian areasU: There are many speciesassociated with streams and riparian areas that are at risk. My students and I have worked on anumber of threatened or endangered species of amphibians. The species include tailed frog(vulnerable), coastal giant salamander (threatened), tiger salamander (BC – endangered), and Oregonspotted frog (endangered globally). The studies include long-term capture-mark-recapture programs,experimental studies of logging impacts on their demography, and experiments of their interactions withother species.22BFuture DirectionsI plan to further move towards ecosystem-scale experiments using small stream basins as experimentalunits. These are long-term plans and we are studying a series of watersheds that will eventually bemanipulated in one way or another. Some examples of the particular watershed-scale studies includeapplied and basic studies using experimental nitrogen loading, augmenting organic matter to streams todetermine the effects of "leakiness" of the system, and continued studies of different harvestingsystems around streams. Small-scale experiments to understand the mechanisms will continue to be akey approach to determining how processes apparent at ecosystem scales are carried through thesystem. In particular the non-additive, or “complex” interactions of multiple variables will remain one ofthe key questions of my experimental work.(b)Research or equivalent grants (indicate under COMP whether grants were obtained competitively (C) ornon-competitively (NC))
