The advertised position is based in Umeå, Sweden, at the Department of forest ecology and management (Swedish university of agricultural sciencees).
The department includes about 100 people of which 11 are professors. Our mission is to advance the understanding of forest ecosystem processes and to progress the principles of forest ecosystem management. For more information:
http://www.slu.se/en/departments/forest-ecology-management/ Project title: Forest regeneration and belowground competition between trees and seedlings
Research subject: Biology
Description:
Interest in alternatives to clearcut rotational forest management is growing. But transitioning to various continuous cover forestry systems or closer to nature forestry requires that adequate forest regeneration can be secured without clearcuts and possibly also without conventional site preparation measures. However, it is common to find very poor seedling growth and several near overstory trees - especially (but not exclusively) in northern pine forests. It has been shown for multiple tree species that shading by overstory canopies cannot fully explain this poor growth, leading to consideration of belowground limitations and competition with larger trees. The current project will use stable isotope labelling techniques to investigate the role of competition for nitrogen. Specifically, the project will test a hypothesis that competition within ectomycorrhizal networks aggravates the situation for small seedlings near large trees. A series of new large-scale field experiments will be established in the initial phase of the project, and the PhD student will be integral to managing them, and will be the main author on scientific publications of results from them.
The goals of the current project is 1) to test the role of belowground competition via mycorrhizal fungi on seedling establishment, 2) identify where the competition effects are the most severe, and 3) to provide a mechanistic understanding of how and where forest regeneration is hampered by nearby trees. This is crucial if alternatives to current forest management practices are to be developed.
The announced PhD position is fully funded for four years, with the expectation that the student will defend their doctoral thesis at the end of this time period. The successful applicant will work under the supervision of Nils Henriksson, professor Torgny Näsholm, and associate professor Sandra Jämtgård at the department of forest ecology and management (Swedish university of agricultural sciences, Umeå, Sweden). The PhD student will belong to a research group with broad expertise ranging from plant physiology and nutrition to forest ecophysiology, which will provide both support and opportunities for scientific discussion and exchange. The group has well established expertise in using stable isotope techniques for studying ecophysiological processes in field, greenhouse, and lab environments.
Applications from Sweden and from abroad are welcome.
