Instream flow modeling is one tool historically used by resource managers to assess habitat
suitability for aquatic species, including fish and benthic macroinvertebrates. Until recently …

Ecology of the Sierra Nevada Yellow-Legged Frog (Rana sierrae) is well understood in high
elevation lakes, but data on habitat preferences in stream-dwelling populations are lacking …

Studies of resource selection at multiple scales are critical to understanding ecological and
evolutionary attributes of a species. We analyzed relative abundance, habitat use, and …

We present a sampling method for use in small to medium-sized streams that is rigorous and
repeatable, and contains the necessary flexibility to be species-or habitat-specific. Our …

The foothill yellow-legged frog (Rana boylii) is a stream-breeding amphibian that has
experienced significant population declines over a large portion of its historical range. This …

Extensive modifications of river systems have left floodplains some of the most endangered
ecosystems in the world and made restoration of these systems a priority. Modified river …

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 …

Species reintroductions provide a model for integrating practical and theoretical aspects of
conservation biology. However, we currently lack a clear understanding of the factors that …

From 1997–1999 we studied one of four known populations of Oregon Spotted Frogs (Rana
pretiosa) in Washington State to investigate patterns of range use, movements, and habitat …

Successful reintroductions of endangered species rely on comprehensive knowledge of
habitat requirements across spatial and temporal scales. To inform designs of reintroduction …
