River ecologist/fish biologist interested in the response of native fish to human alterations to the environment (good & bad). She/her.
Kurt Fausch has a new book out now (just ordered my copy) about developing an ethic for rivers. I was a huge fan of Kurt’s first book, For the Love of Rivers (I bought copies for everyone in my immediate family), and I’m maybe even more excited to read A Reverence for Rivers.

When baby salmon emerge from the gravel, how far do they disperse to summer rearing grounds? We haven't known until now (at least at the population scale), because they're too small to tag. In a paper just out, we answered this question using parentage-based (genetic) tagging! tinyurl.com/39b2sfjd

Background For many aquatic taxa, juvenile dispersal from spawning locations to rearing habitats is a critical process influencing individual fitness and population dynamics. However, our understandin...

Redbands also tend to do better in warmer temps than their coastal counterparts and are more resistant to C. shasta infections. The adfluvial Redbands in the upper Klamath can be as big as steelhead!
“Redband” is the name given to native, interior populations of rainbow trout.
The rainbow trout has been introduced around the globe. Pure populations of redband trout can be tough to find, often in small streams in the wild places of the northwest US.

Police are not primarily crime fighters, according to the data
A new report adds to a growing line of research showing that police departments don’t solve serious or violent crimes with any regularity, and in fact, spend very little time on crime control, in contrast to popular narratives.

Alaska used to be one of the few remaining strongholds for wild Pacific salmon.
But Alaska's wild salmon can no longer withstand annual releases of billions of hatchery pink salmon, degrading ocean conditions (i.e. marine heatwaves) and destruction of the marine ecosystem from industrial trawling.

For a number of years now, I’ve had a policy that I don’t submit to nor will I review for MPDI and Frontiers. This analysis supports that decision.
It’s no reflection on the many excellent papers and studies that have been published in them, but rather on their editorial and business practices.

This is something that has galled me for a while—folks talking about rivers as if they were just conduits of water & materials to the ocean and not complex, dynamic ecosystems in their own right.
Note that rivers are not simply conveyor belts of plastics to the sea. A substantial amount of microplastic will deposit & accumulate in river sediments. Concentrations in some rivers are as high as the world's most contaminated ocean sediments: redpath-staff.mcgill.ca/ricciardi/Cr...
