Managing Surface Water-Groundwater to Restore Fall Flows in the Cosumnes River

Declining fall flows are limiting the ability of the Cosumnes River to support large fall runs of Chinook salmon.

Transferability of habitat suitability criteria for a stream breeding frog (Rana boylii) in the Sierra Nevada, California

River environments are some of the most highly modified ecosystems in the world. Dams, channelization, and water diversions disrupt ecological interactions and connectivity (Ligon et al. 1995; Power et al. 1996; Ward et al. 1999).

Ecology and Management of the Spring Snowmelt Recession

We present a conceptual model for the ecology of the spring snowmelt recession based on the natural flow regime that relates the quantifiable components of magnitude, timing, and rate of change to abiotic and biotic factors that govern riverine processes.

Water velocity tolerance in tadpoles of the Foothill yellow-legged frog (Rana boylii): Swimming performance, growth, and survival

We explored the effects of large magnitude flow fluctuations in rivers with dams, commonly referred to as pulsed flows, on tadpoles of the lotic-breeding Foothill Yellow-legged Frog, Rana boylii.

Dynamic flow modelling of riverine amphibian habitat with application to regulated flow management

In regulated rivers, relicensing of hydropower projects can provide an opportunity to change flow regimes and reduce negative effects on sensitive aquatic biota. The volume of flow, timing and ramping rate of spring spills, and magnitude of aseasonal pulsed flows have potentially negative effects on the early life stages of amphibians, such as the Foothill yellow-legged frog (Rana boylii).
