用于确定生物多样性高的地点的临界值有可能影响哪些物种被确定为相关生物指标。我使用的数据，长角甲虫和IndVal程序进行敏感性分析，通过不同的定义高多样性网站从上50%的网站上5%的网站。分析进行了在所有级别的网站类型的基础上，目前在森林网站的树种。三个物种出现了高多样性网站的强有力的指标。虽然这些物种的指标值几乎总是统计上显着的网站类型学（所有森林网站）的高层次的定义多样性有很大的影响，这些值。所有这三个物种都表现出增加，其指标值较高的截止值高多样性网站，这表明一个相对嵌套的物种。
The cutoff used to determine sites of high biological diversity has the potential to influence which species are identified as relevant biological indicators. I used data on longhorned beetles and the IndVal program to conduct a sensitivity analysis by varying the definition of high diversity sites from the upper 50% of sites to the upper 5% of sites. The analysis was carried out at all levels of a site typology based on the tree species present at the forested sites. Three species emerged as strong indicators of high diversity sites. Although the indicator values for these species were almost always statistically significant within the upper level of the site typology (all forested sites) the definition of high diversity had a large impact on these values. All three species showed an increase in their indicator values with higher cutoffs for high diversity sites suggesting a relatively nested set of species.
