　　报告人简介： 

　　Dr. Case is a Lecturer in GIS and Remote Sensing at Lincoln University, near Christchurch in the South Island of New Zealand. He has BSc and MSc degrees in Forest Science from the University of New Brunswick in Canada, and a PhD in Ecology from Lincoln University in New Zealand. Dr. Case’s research involves applying spatial technologies, statistical analyses, and simulation modelling methods to understanding ecological patterns and processes at multiple scales. He is collaborating with Prof. Eryuan Liang at the Institute for Tibetan Plateau Research, funded by a New Zealand-China Scientist Exchange Program Award.   

　　报告内容介绍： 

　　Despite New Zealand’s relatively small size, mountain landscapes occupy over 40% of the country’s land area, spanning eight degrees of latitude and 10 degrees of longitude. Across these mountains, tree species of the family Nothofagaceae (the “southern beeches”) form 1000s of kilometres of predominately natural treelines. These treelines display enormous variability in altitudinal positions, varying from below 800-m to over 1500-m in elevation. In this talk I will provide a brief overview of New Zealand treelines in the context of treelines globally. Next, I will outline some recent research aimed at: (i) characterising New Zealand’s southern beech treelines using GIS and landscape ecology methods, and (ii) understanding the causes of treeline variability across the country.
