Climate change effects on alpine plant community dynamics

A climate change experiment with open top chambers (OTCs) was established in the Dryas octopetala heath on Sanddalsnuten in 2000. Combined warming and nutrient addition has increased productivity and grass dominance at the cost of mosses, lichens, and small herbs, resulting in decreased diversity. In a seed sowing experiment we examined the relative role of dispersal and local interactions for alpine plant community diversity under climate warming. The long term effects of warming and local interactions on species recruitment and community dynamics will be examined in the coming years. This project is part of the International Tundra Experiment (ITEX).

Project start: 2000

Duration: long term

Project leader:

Kari Klanderud, Norwegian University of Life Sciences and University in Bergen

 

We examine the effects of herbivory on plant community recovery after environmental changes.
