My past work with Prof. John Reynolds at Simon Fraser University, looked at the influence Pacific salmon have on aquatic and terrestrial ecosystems. We collated evidence about the relationships between Pacific salmon and a diverse range of ecosystem components, such as the diversity and abundance of insects, birds and plants.
We were interested in how many salmon were required in a stream before the effects of nutrient addition and bioturbation plateaued. This research has implications for ecosystem-based fisheries management, suggesting the need to consider not only the salmon populations, but also the flow-on effects to stream and forest ecosystems.
