Table 4 Results from the General Lineal Model (GLM Analysis of Covariance) testing the effects of locality (PNECh, PECM, Jilotepec, and Juchitepec), oak species ( Quercus crassipes and Q. rugosa ), host-plant genetic diversity (expected heterozigosity, estimated with microsatellites and RAPDs data), and the interaction L × S on canopy arthropod diversity and biomass
