Because I’m currently taking the California Certified Naturalist class, I’m spending more time than usual looking at and photographing various organisms. I’m astonished at the diversity of organisms that I saw this week within a 45 minute drive of our house. I managed to see organisms from four kingdoms — plants, animals, fungi, and Chromista (which includes brown algae). Going down one taxonomic level, I saw organisms from over a dozen different phyla (for animals) or divisions (for the other three kingdoms).
This represents an astonishing evolutionary diversity: green algae, red algae, vascular plants; sac fungi and allies, mushrooms and allies; brown algae; sea anemones and allies, molluscs, sea stars and allies, arthropods, ringed worms, flatworms, chordates. And I saw eight of these taxonomic groupings within a five minute walk from my desk.
I have a tendency to focus on flowering plants and vertebrates, while ignoring other organisms. Sometimes it’s good to remind myself how much biological diversity is in my own back yard.
