摘要: Biological indicators measure components of the biota and are used to give general information about complex ecosystems in which they occur, playing key roles conservation planning management. This study illustrates impact habitat change by factors that extrinsic habitats question importance spider responses aiding management decisions. The illustrated existence environmental represent other biota. conclusions drawn from this have important implications for protected areas with grazing herbivores occurrence alien invasive plants. Grazed sites showed highest abundance, diversity species richness, while ungrazed had lowest. no has negative
