All semester I’ve been taking my Ecology students out in the field every Friday. We’ve visited rivers, forests, natural reserves, endemic habitats, and fish hatcheries–none of which fall into my area of expertise. This year I have several students interested in various aspects of food production, natural/holistic health practices (which sometimes conflict with actual science!),…
Marine invertebrates
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….
What is essential is invisible to the eye
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…
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 flowers have brunch
When low tides occur at or before dawn, a marine biologist working the intertidal is hungry for lunch at the time that most people are getting up for breakfast. And there’s nothing like spending a few morning hours in the intertidal to work up an appetite. At least that’s how it is for me. Afternoon…
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…
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…
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…
