要确定联合收割机的实际可行性和生态价值相结合的高性能指标分类群，就需要了解调查不同分类群的成本和效益。我们提出了一个通用的和新颖的框架，以确定这样的类群，并说明我们的方法，使用大规模的评估14个不同的高等类群在三个森林类型在巴西亚马逊，估计标准化的调查成本和生态和生物多样性指标值为每个tax.Survey成本变化了三个数量级，而蜣螂和鸟类则特别适合于对研究区域生境变化的生态后果进行评估和监测。然而，对这些类群的专门关注是以牺牲对其他群体多样性模式的理解为代价的。为了提高生物多样性研究的成本效益，我们鼓励结合更明确的研究目标和使用客观的循证方法来选择研究类群。
The identification of high-performance indicator taxa that combine practical feasibility and ecological value requires an understanding of the costs and benefits of surveying different taxa. We present a generic and novel framework for identifying such taxa, and illustrate our approach using a large-scale assessment of 14 different higher taxa across three forest types in the Brazilian Amazon, estimating both the standardized survey cost and the ecological and biodiversity indicator value for each taxon. Survey costs varied by three orders of magnitude, and dung beetles and birds were identified as especially suitable for evaluating and monitoring the ecological consequences of habitat change in our study region. However, an exclusive focus on such taxa occurs at the expense of understanding patterns of diversity in other groups. To improve the cost-effectiveness of biodiversity research we encourage a combination of clearer research goals and the use of an objective evidence-based approach to selecting study taxa.
