The spring semester started this week, which means that every Friday I’ll be taking my Ecology students on field trips. Yesterday’s field trip, the first of the class, was to Rancho del Oso and Waddell Beach. Every year I’ve taken the students to these sites to visit two different habitats: forest and beach. And all…

Seasonality
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…
I return to the field
For a number of reasons–a lingering injury to my bum knee, scheduling difficulties, and ongoing postconcussion syndrome–I missed the autumn return of the minus tides. At this time of year the lowest tides are in the afternoon, and at the end of the day I just didn’t have the energy to deal with field work….
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…
Playing in the sand, for science
This semester I am teaching a lab for a General Biology course for non-majors. I polled my students on the first day of lab, and their academic plans are quite varied: several want to major in psychology (always a popular major), some want to go into business, a few said they hope to go into…
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…
Things strange and beautiful
This weekend I was supposed to take a photographer and his assistant into the field to hunt for staurozoans. I mean a real photographer, one who has worked for National Geographic. He also wrote the book One Cubic Foot. You may have heard of the guy. His name is David Liittschwager. Anyway, his assistant contacted…
Squidlets
Every once in a while some random person drops off a creature at the marine lab. Sometimes the creature is a goldfish that had been a take-home prize at a wedding over the weekend (now weddings taking place at the Seymour Center are not allowed to include live animals in centerpieces). Once it was a…
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…
