A crucial issue for landscape ecologists is identifying the spatial extents at which a landscape affects species occurrence. Multi-scale analyses are usually conducted to identify the ‘scale of effect', that is, the spatial extent associated with the best relationship between landscape variables and species occurrence, which is assumed to be related to species traits. However, few guidelines exist to determine the range of distances to be investigated.

多远才够？预测野生蜜蜂的影响规模

景观生态学家的一个关键问题是确定景观影响物种发生的空间范围。通常进行多尺度分析以确定“影响尺度”，即与景观变量和物种发生之间的最佳关系相关的空间范围，假设与物种特征有关。然而，很少有指导方针来确定要调查的距离范围。
