Evidence for hybridization between sympatric holm-oak and cork-oak in Spain based on diagnostic enzyases, leucine amino peptidases and acid phosphatases respectively. Among the 35 studied individuals, 29, 5 and 1 were identified as holm-oak, cork-oak and hybrid respectively. Such diagnostic markers are likely to be useful to detect and remove hybrids at the juvenile stage in areas where the holm-o

Temperature-vegetation structure interaction: the effect on the activity of the ant , (L.)Circadian variation in temperature seems to be related to structural characteristics of the vegetation, with an apparent influence of the plant micro- and meso-environments analyzed. The activity of a population of granivorous ants (. (L.)), studied in the same area, showed a clear dependence on amb

The influence of summer and winter stress and water relationships on the distribution of , L.e northeastern Iberian Peninsula. Water requirements, water status limits necessary for a positive carbon budget and the functional canopy behaviour in the face of abiotic stress were evaluated, in order to determine which factors influence the geographical range of these forests.The results showed

The results are discussed in term of stomatal regulation and changes in soil-to-leaf hydraulic conductance of water flow, both induced by changes in leaf water potential. For this purp

Evaluation of actual evapotranspiration of a , L. stand by the Bowen Ratio-Energy Budget method5 mm day., with a peak rate near 0.6 mm hour.. The phenomenon of thermal inversion, quite common in mediterranean climates, seemed to play a significant role in reducing evapotranspiration, by promoting dew formation and delaying the establishment of fluxes of latent and sensible heat away from the
