Variations in water use by a mature mangrove of Avicennia germinans, French Guiana [PDF]

open access: yes, 2009
In the tropical intertidal zones, little is known on water uptake by mangroves. Transpiration rates are generally measured at leaf level, but few studies exist on water use at tree or stand levels.

Sap flow index as an indicator of plant water status [PDF]

open access: yesTree Physiology, 1999
Night and especially predawn tree water status is an important indicator of drought stress in trees. Leaf water potential (LWP) is frequently used as a measure of tree water status and hence drought stress; however, there are difficulties associated with sampling foliage from tall trees and determining LWP automatically.

Historical impact of water infrastructure on water levels of the Mekong River and the Tonle Sap System [PDF]

open access: yesHydrology and Earth System Sciences, 2014
Abstract. The rapid rate of water infrastructure development in the Mekong basin is a cause for concern due to its potential impact on fisheries and downstream natural ecosystems. In this paper we analyse the historical water levels of the Mekong River and Tonle Sap system by comparing pre and post 1991 daily observations from six stations along the ...
