The index (Coralligenous Assemblage Index, CAI) that we proposed was based on three selected metrics (Bryozoa percent cover, sludge percent cover, builder species percent cover) and considers depth; it was positively and significantly linked to anthropization (related to water quality).
In each quadrat, we recorded percent cover of each plant species.
Plant diversity, species richness, biomass, and percent cover were all negatively affected by increasing tadpole densities.
In contrast, percent cover of woody vegetation is the most important factor mitigating UHI effects.
The results of this study indicate that CAI is useful for quantifying plant litter cover, even at low percent cover.
Species richness of grasses, presumably because of sowing low-diversity mixtures, and hunting spiders decreased with percent cover of IAA.
The strong predictive value of aspect, slope and percent cover in boulder and SCREE were identified at all scales.
Increases commonly occurred in the percent cover of hairy wild rye (Leymus innovatus (Beal) Pigler) and fireweed (Chamerion angustifolium (L).
In particular, urban land use, although small in percent cover, exerted a disproportionately large influence both locally and over distance.
An increase of the species number led to more stable end communities and a higher percent cover of the landscape.
Species richness increased with percent cover of grassland in the surrounding landscape, and activity density followed the same trend.
