Fish domination of avian food webs
By Christine Parisek & Jon Walter . . . Food webs are the backbones of ecosystems: they chart the flow of energy through ecosystems in terms of who eats whom, and their structure helps determine whether an ecosystem will be stable over time.

Day 10 – One lucky penny
By Christine A. Parisek . . . Imagine a time you were standing at the edge of a creek – perhaps small pebbles and cobblestone were stacked along the shallow water edge, aquatic vegetation pushed its way in between, and a light breeze rustled the trees around you as the water swirled and lapped playfully…

Ash in the Rivers: The Unexplored Consequences of Post-Wildfire Runoff on Freshwater Fish
By Garfield Kwan & Christine Parisek Wildfires have become a hot topic. Although wildfires are a natural part of some ecosystems (e.g. the chaparral biome), megafires (fires that burn >100,000 acres of land) are becoming increasingly common as the climate continues to warm and droughts intensify. As of late, California’s fourth largest wildfire, the 2024 Park fire, charred…

How the Grinch Saved the Creek: A Collection of California Water Fables
By Scrooge Jones Did you know the Grinch played a crucial role in the return of salmon to Putah Creek? It was actually a pretty big deal.

Shell-shocking Details About Freshwater Mussel Reproduction
By Andrew L. Rypel, Miranda Bell Tilcock, and Christine A. Parisek One of our favorite aspects of teaching is (occasionally) being able to really surprise a student.

A “Peak” into California’s Alpine Lakes and their Food Webs
