Evolutionary ecologist and conservation biologist with an affinity for freshwater and anadromous fish. Postdoc at UC Berkeley.

Scatterplot with the number of juvenile coho salmon on the x axis (a proxy for intraspecific competition) and proportion of non-natal rearing on the y-axis, showing no relationship
Scatter plot with mean daily flow (cfs) on the x axis and the proportion of fish non-natal rearing on the y axis, showing a non-linear increase in the proportion of non-natal rearing as flow increases.
Raincloud plot with rearing strategy on the x axis and water year day of emigration on the y axis showing more variable but earlier distribution of emigration timing for non-natal than natal rearing fish.
Proprtional bar graph showing that natal rearing is more common among juvenile salmon, but that non-natal rearers comprise a greater proportion of adult returns.
Graph with day of water year on the x-axis and count on the y axis, showing multimodal variation in the timing of fish migrating down from their natal habitat (shown in blue lines) and also variation in their timing of emigration (shown in gold lines)
A map showing Willow Creek extending east-by-southeast from the Russian River estuary. Insets show a tidal marsh near the confluence, a braided stream through a dense alder forest in the middle portion of the creek, and a single channel through a second growth redwood forest in the upper portion of the creek. Red points show PIT antennas at the confluence, and at 3.7km up the stream (about halfway up)
When despair for the world grows in me and I wake in the night at the least sound in fear of what my life and my children’s lives may be, I go and lie down where the wood drake rests in his beauty on the water, and the great heron feeds. I come into the peace of wild things who do not tax their lives with the forethought of grief. I come into the presence of still water. And I feel above me the day-blind stars waiting with their light. For a time I rest in the grace of the world, and am free.
