Legacies of Stream Channel Modification Revealed Using General Land Office Surveys, with Implications for Water Temperature and Aquatic Life

Land use legacies can have a discernible influence in present-day watersheds and should be accounted for when designing conservation strategies for riverine aquatic life. We describe the environmental history of three watersheds within the Grande Ronde subbasin of the Columbia River using General...

Reconditioning Snake River B-Run Steelhead Kelts: A Research Report

Using Genetic Pedigree Reconstruction to Estimate Effective Spawner Abundance from Redd Surveys: An Example Involving Pacific Lamprey Entosphenus tridentatus

Redd surveys are a commonly used technique for indexing the abundance of sexually mature fish in streams; however substantial effort is often required to link redd counts to actual spawner abundance. In this study, we describe how genetic pedigree reconstruction can be used to estimate effective...
