Arthropods dataset from different genetically modified maize events and associated controls

The food-web graph index data contains the number of nodes (species) and the number of edges (trophic relations between species) for each maize entry. Values in degree represents the number of trophic links toward the species in food web (number of other species feeding with this species). Values out degree represents the number of trophic links from the species (number of other species eaten by the species). K indexes or keystone index are quantitative rank of species by their topological importance. As the K index increase the species importance are higher in the functioning of the food-web.<br>Sample 1_Pitfall Traps_2007-2008 contains arthropods data collected with pitfall traps in different maize development stages. (eight leaves stage (V8), twelve leaves stage (V12), vegetative stage, tasseling (VT) and reproductive stage, milk (R3)). <br><br>Sample 2_Yellow Traps_2007-2008 contains arthropods data collected with yellow traps in different maize development stages.
