plant_pol_vazquez: Vazquez & Simberloff plant-pollinator webs
Eight bipartite networks of plants and pollinators, from the Nahuel Huapi National Park and surrounding areas in Rio Negro, Argentina, from September 1999 to Feburary 2000. Edge weights represent the frequency of species interaction, and there is a common set of vertices across all eight webs.
This network has 144 nodes and 36 edges.
