The effects of juvenile cutthroat trout on survival, growth, and behaviors of Pacific giant salamander larvae and factors contributing to their coexistence in small streams

Purpose

Two aspects of behavioral interactions between cutthroat trout and Pacific giant salamander larvae will be investigated in artificial pools placed in the stream channel. The first experiment will test palatability of salamanders to trout. Ind. Trout wil

Lotic Intersite Nitrogen eXperiment (LINXII): Nitrate uptake and retention in streams: mechanisms and effects for human disturbances from stream reaches to landscapes

Purpose

We will doing a stable isotope tracer study to look at uptake, transformation and retention of nitrate in stream ecosystems. This will entail some intensive water sampling efforts on our part, as well as measurements of channel geomorphology and hydrolog
