As part of its efforts to determine environmental and phenological states from radar imagery, the Boreal Ecosystem-Atmosphere Study (BOREAS) Remote Sensing Science (RSS)-17 team collected in situ tree xylem flow measurements for one growing season on five Picea mariana (black spruce) trees. The data were collected to obtain information on the temporal and spatial variability in water uptake by trees in the Southern Study Area-Old Black Spruce (SSA-OBS) stand in the BOREAS SSA. Temporally, the data were collected in 30-minute intervals for 120 days from 31 May 1994 until 27 September 1994. The data are stored in tabular ASCII files. The xylem flux data are available from the Earth Observing System Data and Information System (EOSDIS) Oak Ridge National Laboratory (ORNL) Distributed Active Archive Center (DAAC). The data files are available on a CD-ROM (see document number 20010000884). Zimmerman, Reiner and Way, JoBea and McDonald, Kyle and Nickeson, Jaime (Editor) and Hall, Forrest G.

The BOREAS RSS-17 team acquired and analyzed imaging radar data from the ESA's ERS-1 over a complete annual cycle at the BOREAS sites in Canada in 1994 to detect shifts in radar backscatter related to varying environmental conditions. This data set consists of dielectric constant profile measurements from selected trees at various BOREAS flux tower sites. The relative dielectric constant was measured at C-band (frequency = 5 GHz) as a function of depth into the trunk of three trees at each site, Measurements were made during April 1994 with an Applied Microwave Corporation field PDP fitted with a 0.358-cm (0.141-inch) diameter coaxial probe tip. The data are available in tabular ASCII files. The data files are available on a CD-ROM (see document number 20010000884), or from the Oak Ridge National Laboratory (ORNL) Distributed Active Archive Center (DAAC). Hall, Forrest G.

The prospect of future climate change has stimulated research into the physiological responses of plants to stress. Water is a key factor controlling the distribution and abundance of plants. This book brings together contributions from a range of experts who have worked on the cavitation of water in the transport system.

Tremendous advances have been made in techniques and application of microscopy since the authors' original publication of Plant Cell Biology, An Ultrastructural Approach in 1975. With this revision, the authors have added over 200 images exploiting modern techniques such as cryo-microscopy, immuno-gold localisations, immunofluorescence and confocal microscopy, and in situ hybridisation. Additionally, there is a concise, readable outline of these techniques. With these advances in microscopy and parallel advances in molecular biology, more and more exciting new information on structure-function relationships in plant cells has become available. This revision presents new images and provides a modern view of plan cell biology in a completely rewritten text that emphasizes underlying principles. It introduces broad concepts and uses carefully selected representative micrographs to illustrate fundamental information on structures and processes. Both students and researchers will find this a valuable resource for exploring plant cell and molecular biology.
