Elberling and Olesen
(1999)
General information
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.
Data type
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.
