My research explores the abundance, diversity, and productivity of salmon populations and their habitats over the last century, and how humans have compromised the resilience of salmon to future global change.

To do so, I use fish scales as my window into the past. I've accessed a unique collection of sockeye salmon scales and biological data extracted from fish caught in commercial fisheries at the mouth of the Skeena River beginning in 1913, and compared the information concealed within these scales with fish from the modern era.

In collaboration with colleagues, my recently published research demonstrates a substantial decline in abundance and diversity of Skeena sockeye populations over the last century, which translates to a simplified watershed portfolio - view our publication in the Journal of Applied Ecology, and read the article Summary.
Currently, I'm investigating changes in growth response of sockeye populations to climate warming and other human influences over the last century...Stay tuned for more.
Additional questions that I'm working on include:
1. Characterization of extinct sockeye salmon populations in the Skeena.
2. Loss of population-specific genetic richness over millennial time-scales.
3. Shifting distribution of salmon in response to climate change
