This study took place in the
subarctic alpine zone of Latnjajaure, in northern Sweden. Field work
was conducted from May 21 to August 23, 1994. The objective was to
describe the plant-flower visitor interaction matrix of this area and
compare it with the characteristics of other subarctic alpine systems
and with pollination systems of lower latitudes, especially in relation
to the role of flies as flower visitors at high latitudes.
The authors recorded their data by
counting the number of visits of each flower visitor species to each
plant species. Regardless of whether insects were observed to forage
for nectar and pollen or to perform sun-basking, they were all
classified as flower visitors and potential pollinators and the plant
species visited were recorded. Data are presented as an interaction
frequency matrix, in which cells with positive integers indicate the
frequency of interaction between a pair of species, and cells with
zeros indicate no interaction
