Highest (246.6 52.7 g m2 ) and lowest (123.2 89.5 g m2 ) peak biomass occurred in 2006 and 2005 respectively. Total soil N within the top 20 cm soil proﬁle ranged between 0.2 0.1% in February and 0.41 0.2% in May, while available soil N was lowest (5 2 mg g 1 soil) in February but increased three-to-ﬁve fold in March and was &gt;17.5 mg g 1 soil at senescence in May. Signiﬁcant (p &lt; 0.001) increase in total N in the aboveground pool occurred between February and May. There was however, no decay in soil N content. Instead, the herbaceous vegetation enhanced soil N input and N retention in the ecosystem. Most of the herbaceous plants were annuals with large reserves of organic N at senescence, which returned to the soil as detritus. The herbaceous vegetation is a critical component of the montado that contributes to N recharge and cycling within the ecosystem</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Landau, Serge</style></author><author><style face="normal" font="default" size="100%">Dvash, Levana</style></author><author><style face="normal" font="default" size="100%">Decandia, Mauro</style></author><author><style face="normal" font="default" size="100%">Cabiddu, Andrea</style></author><author><style face="normal" font="default" size="100%">Shapiro, Fira</style></author><author><style face="normal" font="default" size="100%">Molle, Giovanni</style></author><author><style face="normal" font="default" size="100%">Silanikove, Nissim</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Determination of Poly(ethylene glycol)-Binding to Browse Foliage, as an Assay of Tannin, by Near-Infrared Reflectance Spectroscopy</style></title><secondary-title><style face="normal" font="default" size="100%">Journal of Agricultural and Food Chemistry</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Animal Nutritional Physiological Phenomena</style></keyword><keyword><style  face="normal" font="default" size="100%">Animals</style></keyword><keyword><style  face="normal" font="default" size="100%">Carbon Radioisotopes</style></keyword><keyword><style  face="normal" font="default" size="100%">Fabaceae</style></keyword><keyword><style  face="normal" font="default" size="100%">Fabaceae: chemistry</style></keyword><keyword><style  face="normal" font="default" size="100%">Goats</style></keyword><keyword><style  face="normal" font="default" size="100%">Hydrolyzable Tannins</style></keyword><keyword><style  face="normal" font="default" size="100%">Hydrolyzable Tannins: analysis</style></keyword><keyword><style  face="normal" font="default" size="100%">Near-Infrared</style></keyword><keyword><style  face="normal" font="default" size="100%">NIRS</style></keyword><keyword><style  face="normal" font="default" size="100%">nutrition</style></keyword><keyword><style  face="normal" font="default" size="100%">pasture</style></keyword><keyword><style  face="normal" font="default" size="100%">poly(ethylene glycol)</style></keyword><keyword><style  face="normal" font="default" size="100%">Polyethylene Glycols</style></keyword><keyword><style  face="normal" font="default" size="100%">Polyethylene Glycols: metabolism</style></keyword><keyword><style  face="normal" font="default" size="100%">Spectroscopy</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2004</style></year></dates><publisher><style face="normal" font="default" size="100%">American Chemical Society</style></publisher><volume><style face="normal" font="default" size="100%">52</style></volume><pages><style face="normal" font="default" size="100%">638-642</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Nutritionists are interested in functional assays of tannins that do not require time-consuming and expensive extraction, such as the 14C-labeled poly(ethylene glycol) (PEG)-binding (PEG-b) assay. This paper reports the application of near-infrared (NIR) spectroscopy to determine the percentage of PEG binding, in place of the 14C-labeled PEG-b assay of tannin, in Mediterranean woodland vegetation. Calibration was done with 53 samples from 14 species and was validated on 25 samples from 10 species. PEG-b ranged between 1.4 and 20.7% in the samples. The calibration obtained by using the modified partial least-squares (MPLS) method, with all wavelengths in the 1100?2500 nm range combined, and the validation were reasonably linear (R?2 = 0.96 and 0.91, respectively). The accuracies, estimated from the standard errors of cross-validation and prediction, were ±1.6 and ±1.7% PEG-b, respectively. The NIRS-aided procedure proposed here can serve as an accurate, inexpensive, time-saving, and environment-friendly functional assay of tannin in Mediterranean browse.

The study utilized a 5.5 ha watershed near the town of Mora, center of Portugal. The watershed contained scattered cork- oak with natural pasture, which is probably the most representative formof landuse in the region. de 1990, que va mostrar la The project used the basic water balance equation, being evaluated incident rainfall, runoff, evapotranspiration and changes in soil water storage. Measurements of the tree stands and canopies were included for the characterization of throughfall and stemflow. Interception was estimated to evaluate its effects onrainfallredistribution and onthe dynarnics of evapotranspiration. Collection of data for the intensive hydrologic study begun in October 1, 1988. During 1989, surface runoff was 10.8 percent of annual rainfall. For the same period, canopy interception by the Quercus suber stand was 15.4 percent and throughfall accounted for 84.6 percent of annual rainfall, as stemfiow was considered negligible. Statistical analysis of data related to the period January, 1990 to May, 1990 is now being undertaken. Itis apparent, however, from the study, that the data sets should be extended through further research to confirm the tentative hydrological trends of the first period.</style></abstract></record></records></xml>
