Ionic dynamics of stemflow on oak trees during a growing season in South Wales, UK / JACK HOUGHTON

Swansea University Author: JACK HOUGHTON

Abstract

The ionic composition of stemflow over the course of early spring to summer (March to June) offers an insight into the movement of ions throughout this small area of the hydrological cycle and its development over the course of a single season. The water is collected from the six selected common oak...
