DESCRIPTION:Isotopes of water provide a window into otherwise invisible as
 pects of the water cycle including sub-surface hydrological pathways and s
 ources of water to trees. In the first part of this talk\, Dr. Bruce Dudle
 y describes application of isotope mixing models to map impacts of invasiv
 e trees on water and nutrient cycles. Secondly\, he illustrates how dual-i
 sotope techniques can be used to examine water sources for shrubs and how 
 simultaneous measurement of sapflow can add support to inferences made usi
 ng isotopes. In the final part of the talk\, he discusses the use of stabl
 e isotopes in national-scale hydrology. To begin\, this work has required 
 us to set up networks of precipitation and river water isotope collections
  across New Zealand. One important part of this discussion is the developm
 ent of national isotope maps (isoscapes) using a range of methods. As a co
 nclusion\, he will briefly discuss future applications of this work.
