General information
This paper
analyzes the relationship between the degree of specialization of
plant and pollinator species and their response to disturbance caused
by introduced cattle. The study was conducted in four grazed and
four ungrazed sites in and around Nahuel Huapi National Park and
surrounding areas in Rio Negro, Argentina from September 1999 to
Feburary 2000. For each site, the plant-pollinator interaction network
was described.
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.
