Variable General Info
Bee community composition ?Comment:Using multiple sampling methods should provide a more complete picture of the bee community during the sampling time (Geroff, Gibbs, & McCravy, 2014). All bees were later identified to species. These data resulted in three response variables that are tested here: bee community composition, bee richness and bee abundance. |

Bee community composition ?Comment:Using multiple sampling methods should provide a more complete picture of the bee community during the sampling time (Geroff, Gibbs, & McCravy, 2014). All bees were later identified to species. These data resulted in three response variables that are tested here: bee community composition, bee richness and bee abundance. |
|
Not reported ?Comment:The Morisita dissimilarity was used for bees. The Morisita dissimilarity matrix is more robust in under sampled datasets, which would be expected for bees. Multivariate analysis results for effects of resources and management on bee community composition after backward selection showed that management and Soil PC1 had the greatest effects. |
