Landscaping Continues: As you may read below and on the Events page, planting areas around our new building got off to a great start on Feb. 14. However, there's more to be done, and all hands will be welcome on coming Saturdays at 9:30, weather permitting. Please check with Chris before you come. Watch'em grow!

In spite of very wet ground, more planting continued on Feb. 21st.

Feb. 18, Luiz Martinelli, Centro de Energia Nuclear na Agricultura, Isotope Ecology Studies in the Amazon Basin. Dr. Martinelli gave us a fascinating overview of the Amazon Basin plus some results of his research on the flow of both nitrogen and carbon from ground level to the air above the forests obtained by measuring the stable isotopes of these elements.

Feb. 25, Nathan Nelson, Tel Aviv Univ., Israel
The Crystal Structure of Plant Photosystem 1. Dr. Nelson presented a wealth of data describing the intimate structure of PS1 and how it has evolved from cyanobacteria to green algae and higher plants. He drew on experimental results from his own laboratory as well as others.

Subject: Global Ecology Landscaping -- delay until 14 February
This week's rain has forced us to delay the landscaping around the new Global Ecology building. The site is too wet for the tractor to come and do the final tilling, and our tree supplier can't get the trees out of the ground for delivery. We are rescheduling for a week from Saturday.
The good news is that, with a 14 February planting date, you can view this as a valentine for the planet. I look forward to seeing you on the 14th, any time after 9:30. As you know, we have 10,000 natives to plant, ranging from grass plugs to valley oaks. Anyone who wants to volunteer to help with the planting is more than welcome. We will provide lunch, gloves, and hand tools.
Earlier, I asked people planning to volunteer to send note to Linda Longoria (mainly for planning the lunch). Unless the delay changes your plans, there is no reason to send a second note.
Most of the plants have arrived and lunch is ordered for Saturday, Feb. 14th See you there at 9:30 or soon thereafter.
See Events page on our Web site for what happened.

Field Lab Meetings Wednesdays, 12-1 PM
February 4, Katie Amatangelo reviewed the paper by Davis, S.D. and H.A. Mooney, 1986. Water use patterns of four co-occurring chaparral shrubs. in Oecologia 70:172-177. Both Mooney and Chris Field offered insites into how this research was conducted in the early eighties on Jasper Ridge.
Feb. 11, Elsa Cleland reviewed the paper: by Huenneke, L.F.; S.P. Hamburg; R. Koide; H.A. Mooney & P. Vitousek. Effects of Soil Resources on Plant Invasion and Community Structure in California Serpentine Grassland in Ecology 71, 478-491, 1990. A variety of orange citrus fruits were tasted.
Feb. 18, Kim Cahill reviewed the paper by Koide, R.T., L.F. Huenneke, S.P. Hamburg & H.A. Mooney. 1988. Effects of applications of fungicide, phosphorus & nitrogen on the structure & productivity of an annual serpentine plant community. Functional Ecology 2:335-344. Different flavors of humus were taste-tested.
Feb. 25, Claire Lunch reviewed a paper by Valentini, R., J.A. Gamon, & C.B. Field. 1995 Ecosystem gas exchange in a California grassland: seasonal patterns and implications for scaling. Ecology 76:1940-1952. We tasted a number of brands of Soy Milk. They all were the same basic vanilla flavor but had subtle differences besides texture and Ca content.
Mar. 3, Jason will review a paper by Gamon, J.A., C.B. Field, M.L. Goulden, K.L. Griffin, A.E. Hartley, G. Joel, J. Peñuelas, & R. Valentini. 1995. Relationships between NDVl, canopy structure, and photosynthesis in three California vegetation types. Ecological Applications 5:28-41.
