Objectif(s): To predict changes at the ecosystem level from a long-term enclosure experiment in high Arctic lakes or ponds that may occur due to increases in UV-B levels.
Description du projet: This study will be done by setting up 6 enclosures in a lake or pond. Two enclosures will be exposed to reduced UV-B levels, two other enclosures will be exposed to ambient UV-B levels, and finally two other enclosures will be exposed to enhanced UV-B levels. Regular measurements will be made of algae and invertebrates biomass, species composition, and pigment; and of algal photosynthesis and end products in all 6 enclosures and in the lake.
