Tree of Life exercise
I've observed species from across 5 different iconic taxa.
- Plants: Least exciting to me is the Coast Live Oak. The tree is in the plants taxa and is a member of the kingdom plantae.
- Birds: Nearby a group of sleeping sea lions, I found a Western Gull trying to rest as well. The gull is in the birds taxa.
- Mammals: The California Sea Lion, seen here drying itself on San Francisco's Pier 39, is a member of the mammals taxa. The sea lions I saw were very cool and interesting to observe.
- Insects: I found a water strider in Strawberry Creek. It was very hard to take a good picture of the water strider as I was photographing it in very low light conditions with a pocket camera. The water strider is an insect.
- Chromista: Most interesting was the instance of phytophthora ramorum, the progenitor of sudden oak death. P. Ramorum is a member of the chromista taxa, a taxa of which I have not seen many examples.

I found an instance of phytophthora ramorum growing on the bark of a Coast Live Oak on the UC Berkeley campus. This affliction causes sudden oak death and is quite prevalent on the Western United States.

Nice job Eric - I'm impressed you got Sudden Oak Death in there!
Thanks! A few years back, one of the oak trees in my backyard died because sudden oak death. I recall that when I helped my dad cut up the tree into logs and, later, when I was splitting the logs into firewood, I noticed that a lot of pieces of bark had this weird white stuff growing on it. When I saw the oak tree bark yesterday, I thought back to what I saw a few years prior.
Cool - Maggi Kelly in ESPM at Berkeley does some cool research on sudden oak death you can check out here: http://kellylab.berkeley.edu/oakmapper/
