Notes from a California naturalist
The nature of Nature
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…
Among photographers and those who watch the sky, last night’s lunar eclipse was an event to stay up late for. In much of California the latest storm left the sky cloudy, but I was lucky to have pretty good viewing for most of the eclipse. The moon was behind clouds at the beginning of the…
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…
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….
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…
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…
When I teach sponge biology to students of invertebrate zoology, I spend a lot of time describing them as phenomenal filter feeders, and suspect that most other professors do the same. There really are no animals that come close to possessing sponges’ ability to remove very small particles from the water. Sponges have this ability…
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…
In the wee hours of Sunday 12 August 2018, the F/V Pacific Quest ran aground near Terrace Point. Over the next 24 hours she broke apart and began leaking diesel fuel into Monterey Bay. Fortunately most of the diesel was removed from the wreck, but the boat itself continued to disintegrate, with a lot of…
This morning I went out on what will probably be my last low tide of the season. We don’t get any good (i.e., below 0 feet and during daylight hours) until November, so it’s time to hang up the hip boots for a few months and work on other things. I had planned to go…
