Impacts of climate change on Arctic plant communities
University of Edinburgh
G+PS regularly provides virtual sessions that focus on admission requirements and procedures and tips how to improve your application.
1. Synthesis of tundra plant community changes to nearly 30 years of experimental warming using a suite of plant traits, including ecophysiology. PhD or postdoctoral study to involve 2-3 years of fieldwork and working with long-term data sets from an experimental study established in the Canadian High Arctic in 1992. 2. Ecological relaxation response of tundra after 30 years of experimental warming. PhD or postdoctoral study of the removal of experimental warming conditions on tundra plants and soils. 3. Landsape phenology patterns in tundra systems in relation to biological and physical conditions. Combination of plot studies and remote sensing using UAV technology for high resolution (temporal and spatial) analysis of plant phenology across a high Arctic landscape. 4. Phenology, growth and reproductive responses of southern populations in warmed high Arctic conditions: a common garden study. A PhD or MSc project involving the continuation of a common garden experiment established in 2011 with local and southern populations of two common forb species. The studies would involve using the Arctic Tundra controlled environment chamber at UBC. 5. Dendroecological studies using Arctic shrub species. Examination of the growth (and reproduction) patterns in up to four shrub species in response to: a) experimental climate change; b) landscape position, snow conditions and climate. The dendrochronological data can be used to reconstruct climate conditions over the past century.
