保护生物学家使用替代物种作为监测或解决保护问题的捷径。指示物种已被用来评估人为干扰的程度，监测其他物种的种群趋势，并确定区域生物多样性高的区域。伞形物种被用来划定栖息地的类型或保护面积的大小，旗舰物种被用来吸引公众的注意。不幸的是，在这些术语上有相当大的混淆，其中一些被松散地使用并且可以互换。我们试图为这些不同术语的应用提供一些澄清和指导。对于每种类型的替代物，我们简要地描述了它在保护生物学中的使用方式，然后检查管理人员和研究人员在选择合适的替代物种时使用的标准。通过并列这些概念，很明显，不同替代物类别的目标和选择标准都有很大差异，表明它们不应该混为一谈。明确说明选择替代物种所涉及的标准，根据这些标准确定一个物种，然后在解决保护问题本身之前进行初步研究以检查物种选择是否合适，如果替代物种在保护生物学中仍然有用，则需要谨慎使用。
Conservation biologists have used surrogate species as a shortcut to monitor or solve conservation problems. Indicator species have been used to assess the magnitude of anthropogenic disturbance, to monitor population trends in other species, and to locate areas of high regional biodiversity. Umbrella species have been used to delineate the type of habitat or size of area for protection, and flagship species have been employed to attract public attention. Unfortunately, there has been considerable confusion over these terms and several have been applied loosely and interchangeably. We attempt to provide some clarification and guidelines for the application of these different terms. For each type of surrogate, we briefly describe the way it has been used in conservation biology and then examine the criteria that managers and researchers use in selecting appropriate surrogate species By juxtaposing these concepts, it becomes clear that both the goals and selection criteria of different surrogate classes differ substantially, indicating that they should not be conflated This can be facilitated by first outlining The goals of a conservation study, explicitly stating the criteria involved in selecting a surrogate species, identifying a species according to these criteria, and then performing a pilot study to check whether the choice of species was appropriate before addressing the conservation problem itself Surrogate species need to be used with gl eater care if they are to remain useful in conservation biology.
