The Department of Ecology and Natural Resource Management (INA) at the Norwegian University of Life Sciences (NMBU) has a vacant three year PhD–position investigating the role of disturbance and competition in determining species distributions on tropical elevation gradients. The study will be conducted in Costa Rica in collaboration with CATIE (“Centro Agronómico Tropical Investigación y Enseñanza”), where the field research will be hosted.
The project will determine how competitive exclusion varies with elevation in mixed-species tropical vegetation communities, and how manipulations that slow or prevent such exclusion might reduce local plant extinctions resulting from increased temperatures.
Specifically we will assess
1) the degree to which competition determines the upper- and lower-elevation distribution of plant species boundaries;
2) the degree to which disturbance histories influence elevation distributions;
3) the ability of disturbance, and interventions based on disturbance, to modify species distributions and contribute to species persistence in situ.
- Satisfy all the requirements of a doctoral degree in NMBU
- Complete a doctoral thesis in tropical plant ecology
- Conduct both field survey and manipulative field studies requiring the candidate to spend several months in the tropics during the first two years.
