Design and performance of experimental constructed wetlands treating coke plant effluents.

Reed beds were chosen to treat effluents from a coke plant in France (Usinor-Sollac, Fos/mer). The pilot is composed by a two-stage gravel bed with subsurface flow and Phragmites australis as plant. This experimental constructed wetland was monitored for one year at steady-state conditions.

Within-tree variation in transpiration in isolated evergreen oak trees: evidence in support of the pipe model theory.

Within-tree variation in sap flow density (SFD) was measured in two isolated evergreen oak (Quercus ilex L.) trees growing in an oak savannah (dehesa) in southwest Spain. Sap flow was estimated by the constant heating method.
