This manual describes procedures for biologic climate eff ect
monitoring in Kobbefjord, Nuuk. The monitoring is a part of
NuukBasic which is a cross-disciplinary ecological monitoring
programme in low Arctic West Greenland. Biological
monitoring comprises the NERO line which is a permanent
vegetation transect, and monitoring reproductive phenology
of Salix glauca, Loiseleuria procumbens, Eriophorum
angustifolium, and Silene acaulis. The progression in vegetation
greenness is followed along the vegetation transect
and in the plant phenology plots by measurement of Normalized
Diff erence Vegetation Index (NDVI). The fl ux of CO2
is measured in natural conditions as well as in manipulations
simulating increased temperature, increased cloud cover,
shorter growing season, and longer growing season. The effect
of increased UV-B radiation on plant stress is studied by
measuring chlorophyll fl uorescence in three series of plots.
Arthropods are sampled by means of yellow pitfall traps as
well as in window traps. Microarthropods are sampled in soil
cores and extracted in an extractor by gradually heating
up soil. The avifauna is monitored with special emphasis
on passerine birds. Only few terrestrial mammals occur in
the study area. All observations of mammals are recorded
ad-hoc. Monitoring in lakes include ice cover, water chemistry,
physical conditions, species composition of plankton,
vegetation, bottom organisms and fi sh. Physical-chemical
parameters, phytoplankton and zooplankton
