Schemske et al. (1978)
General information
Populations
of seven early flowering, low-growing, perennial woodland herbs
were studied in a 24 hectare sit in Brownfield Woods, close to Urbana,
Illinois, U.S.A. The sequence and variety of flowers visited by
individual insects were recorded for the first foraging insect observed
in a randomly selected, 1 m2 quadrat located within a 10x10 m grid
that included representatives of several plant species.
Data type
The authors
recorded their data by counting the number of visits of each flower
visitor species to each plant species. 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.
