About a year and a half ago I wrote about salmonids and beavers in the Lake Tahoe-Taylor Creek region, specifically about the non-native kokanee salmon (Oncorhynchus nerka) that were introduced into the region in the 1930s and 1940s as a game fish. Since then the kokanee has displaced the only salmonid native to the Tahoe…
Familiarity breeds wonder
This week I celebrate the return of the early morning low tides! I was very much looking forward to this tide series, and even though I am in class on Tuesday, Thursday, and Friday mornings I wanted to go out on as many of the tides as possible. On Wednesday morning I went out to…
A tourist in the nation’s capital – Day 4
Library of Congress I was completely unprepared for how astoundingly beautiful the Library of Congress is. From the outside it looks like another of the many federal buildings constructed in the Classical style. The interior, though, was spectacular. The ceiling of the Great Hall is magnificent–take a look at this stained glass! We joined a…
A tourist in the nation’s capital – Day 3
National Archives We spent the morning waiting in line to see things in the National Archives building. The lines to get in were very long, and even though we’d bought a membership the night before so that we could bypass the entry line, once we got inside the building there were more lines to go…
A tourist in the nation’s capital – Day 2 (part 2)
Lincoln Memorial This is one of the most easily recognizable monuments in Washington, DC. It graces the back of our $5 bill and sits directly across the Reflecting Pool from the Washington Monument. Everybody knows what it looks like. From the outside, especially from the bottom of the steps, this is another imposing marble edifice….
A tourist in the nation’s capital – Day 2 (part 1)
Monday 26 March 2018 — Memorials On Monday we ventured south of the Mall to the Tidewater area, where an extension of the Potomac river floods into a basin and forms a tidal pond. This area is where the famous cherry trees of Washington, DC, are concentrated, and we hoped to catch some of the…
A tourist in the nation’s capital – Day 1
Spring break for me this year was the last week of March. I generally don’t travel far for spring break because it’s nice to have a week of nothing to do but not be working. This year, though, we decided to visit Washington, DC, for most of the break. I had never been before and…
Saving a species
How does a group of people go about trying to save a federally endangered species? The answer, of course, depends on the species. However, you can bet your bottom dollar that it takes a tremendous effort over many years by many dedicated and talented people, all of whom know that in the end their work…
Birds of a feather
For a long time now I’ve wanted to document a phenomenon that I’ve observed many times: the way that some birds change color when they move from the light into the dark. I’m sure you’ve noticed this before, in the vibrance of a peacock’s tail that turns to black when the bird moves into the…
Getting skunked by birds
This week I took my Ecology students to the Younger Lagoon Reserve (YLR) on the UC Santa Cruz Coastal Science Campus. The YLR is one of 39 natural reserves in all of the major ecosystems throughout the state of California. The UCSC campus administers five of the reserves: Younger Lagoon, the Campus Reserve, Fort Ord Natural…
