Ollerton et al. (2003)
General information
The study was
conducted in the KwaZulu-Natal region of South Africa. During 3
months of fieldwork the flower visitors and pollinators to an assemblage
of nine asclepiads at an upland grassland site were studied. Two
of the specialized pollination systems that were documented are
new to the asclepiads: fruit chafer pollination and pompilid wasp
pollination (the latter is almost unique in the angiosperms).
Data
type
The authors
recorded their data by counting the number of individual flower
visitors observed and/or caught on each plant species. The total
number of individuals observed on each plant species provide a rough
estimate of the level of visitation that each species received.
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.
