Davidson & Fisher
(1991)
General information
In this paper
the authors discuss why it is wrong to assume that reciprical extreme
specialization is a prerequiste for coevolution and consider how
different kinds of asymmetry in specialization lead to different
forms of coevolution.
Data type
The authors
recorded their data by counting the number of visits of each ant
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.
