The main objective of this study was to evaluate the role of intervessel contacts in determining the patterns of hydraulic integration both within and between xylem sectors. The degree of intervessel contacts and the lateral exchange capability within and between sectors were examined and correlated in different xeric shrubs. A dye injection method was used(More)
An inventory was carried out at five stations in the oasis of Ziban, an oasis that is characterized by its high-quality dates, in order to study the relationships between the oasis ecosystem and its insect fauna. Specimens were sampled using pitfall traps containing ethylene glycol as a preservative. In total, 115 arthropod species were collected during 5(More)
By using a simple and rapid technique, the degree of vessel deviations in the stem xylem could be evaluated and compared between different plant species. The degree of vessel deviations was suggested to be one of the main factors determining the hydraulic integration in woody stems. The main objective of this study was to investigate the role of vessel(More)
The fact that the porosity and permeability of intervessel pit pathways are significantly reduced by low ionic strength (deionized water) evokes the question of to what degree the pit membrane permeability can be reduced, and whether the network of laterally connected vessels can be affected by low ionic strength. Isolated stem segments of Tamarix gallica(More)
