People who moved here from other states often say that California doesn’t really have seasons. I think what they mean is that in general we don’t oscillate between frigid winters and hot, humid summers. The Pacific Ocean moderates weather conditions through most of the state, giving us our Mediterranean climate characterized by a short rainy…

Webbed feet, but not a duck!
A few years ago I had a student, Brett, who had played baseball while he was in high school. One day in lab the students and I were chatting about nothing in particular when the conversation turned to the difficulty of memorizing the scientific names of all the animals they were studying. We got into…
On fragile wings of steel
The other day I joined the Cabrillo College Natural History Club (NHC) on a natural journal walk through Natural Bridges State Park and Antonelli Pond here in Santa Cruz. The NHC is a student club at the college where I teach, and I attended one of their meetings early in the semester. It’s a very…
Green
The marine macroalgae, or seaweeds, are classified into three phyla: Ochrophyta (brown algae), Rhodophyta (red algae), and Chlorophyta (green algae). Along the California coast the reds are the most diverse, with several hundred species. The browns have the largest thalli (the phycologists’ term for the bodies of algae), including the very large subtidal kelps as…
The other side of the Bay
Monterey Bay is shaped like a backwards letter ‘C’, with Santa Cruz on the north end and the Monterey Peninsula on the south end. The top of the ‘C’ is comparatively smooth, while the bottom is punctuated by the Monterey Peninsula, which juts north from the city of Monterey. The most striking geologic feature is…
A steady diet of worms
Today is the first day of the week of low tides dedicated to Snapshot Cal Coast, a statewide citizen science project headed in my area by the California Academy of Sciences. This week groups and individuals will be making photographing the organisms they see in the ocean or along the coast, and uploading observations to…
Blitzing an old military base
This weekend a subset of my students and I spent a day at the Fort Ord Natural Reserve (FONR) to participate in the 2018 spring Bioblitz. We were supposed to visit FONR for a class field trip in early March to do some vegetation studies, but that trip was rained out. Today’s visit was sort…
Rediscovery of a lost species
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…
