摘要: AbstractMultilevel hierarchical regression was used to examine regional patterns in the responses of benthic macroinvertebrates and algae urbanization across 9 metropolitan areas conterminous USA. Linear regressions established that (intercepts slopes) invertebrates varied among areas. Multilevel models were able explain these differences on basis region-scale predictors. Regional type land cover (agriculture or forest) being converted urban climatic factors (precipitation air temperature) accounted for response based ordination scores, total richness, Ephemeroptera, Plecoptera, Trichoptera average tolerance. climate antecedent agriculture also salt-tolerant diatoms, but other diatom metrics (%...
