Test application of the laser-induced fluorescence transient (LIFT) instrument
The photosynthetic machinery that enables plants to convert sunlight to chemical energy has two means of dissipating light energy that exceeds a leaf's needs: fluorescence, which is the instantaneous re-emission of light of another wavelength, and heat. Leaf fluorescence can also be actively stimulated with an external light source, and this has become a powerful technique for studying photosynthesis by individual leaves. A new experiment at the Sun field station is extending the approach to plant canopies by inducing fluorescence with an eye-safe laser.
The instrument looks out an east-facing window of the building and focuses a laser on nearby plants. As the laser strikes a clump of leaves, light energy is absorbed by the pigment chlorophyll, and the amount of fluorescence is determined by both the amount of light absorbed and the amount not used in photosynthesis or released as heat.
The laser is programmed to emit pulses of light in rapid succession, varied with ... Read More
JRBP faculty director Chris Field to receive Heinz Award for environmental science and leadership
Stanford researcher and JRBP faculty director Chris Field will be one of the 10 recipients of the 2009 Heinz Awards. The Heinz Family Foundation is recognizing Field "for his leadership and innovation in carbon cycle and climate science."
Field, a professor of biology and earth systems science at Stanford, also serves as the director of the Carnegie Institution's Department of Global Ecology and is a co-chair of IPCC Working Group 2.

Jasper Ridge provides hands-on learning for local students
Local high school students are learning ecology at Jasper Ridge Biological Preserve through the Redwood Environmental Academy of Leadership (REAL), a program based at Redwood High School in Redwood City.
The REAL program is funded by a grant from the Stanford Initiative on Improving K-12 Education.
