摘要

一个多世纪以来,生态学家一直使用营养状态(TS)的概念来表征水生生态系统的生物生产力。然而,已经出现了多种TS分类方案,每个方案都依赖于各种可测量的参数作为生产力的代理,以满足特定用途的需求。通常,叶绿素a、磷和Secchi深度用于根据自养产量对TS进行分类,而磷、溶解有机碳和真色用于根据自养和异养产量对TS进行分类。这两种分类方法都旨在广泛地表征生态系统的功能,但在这些特征中考虑了不同程度的自养和异养过程。此外,不同的分类方案可能造成对生态系统完整性的不一致解释。例如,美国的《清洁水法》专门关注藻类对水质的威胁,根据营养负荷的富营养化来制定。这种用法缺乏关于非藻类对水质的威胁的信息,例如与溶解的有机碳负荷有关的营养不良。因此,用于确定富营养化和营养不良的TS分类方案可能类似地涉及生态系统(例如,贫营养化和富营养化),但这些分类来自不同的代理。当跨学科项目采用不同的TS框架时,TS分类方案中的这些不一致性可能会变得更加复杂。尽管存在这些缺点,TS仍然可以用于将复杂水生生态系统功能的信息提炼成一组可概括的期望。将复杂信息提取到TS索引中是非常有用的,因此应该明确地处理和解决使用不一致的问题。为了强调不同的TS分类方案的后果,我们提出了三个案例研究,其中对TS概念的更好理解促进了淡水研究、管理工作和跨学科合作。为了增加TS的透明度,水生科学可以从包括代理变量,生态系统类型以及用于分类TS的时空域的信息中受益。随着水生科学领域的扩展和气候不规律性的增加,我们强调重新评估基本概念(如TS)的重要性,以确保它们与不断发展的科学兼容。

For over a century, ecologists have used the concept of trophic state (TS) to characterize an aquatic ecosystem's biological productivity. However, multiple TS classification schemes, each relying on a variety of measurable parameters as proxies for productivity, have emerged to meet use-specific needs. Frequently, chlorophyll a, phosphorus, and Secchi depth are used to classify TS based on autotrophic production, whereas phosphorus, dissolved organic carbon, and true color are used to classify TS based on both autotrophic and heterotrophic production. Both classification approaches aim to characterize an ecosystem's function broadly, but with varying degrees of autotrophic and heterotrophic processes considered in those characterizations. Moreover, differing classification schemes can create inconsistent interpretations of ecosystem integrity. For example, the US Clean Water Act focuses exclusively on algal threats to water quality, framed in terms of eutrophication in response to nutrient loading. This usage lacks information about non-algal threats to water quality, such as dystrophication in response to dissolved organic carbon loading. Consequently, the TS classification schemes used to identify eutrophication and dystrophication may refer to ecosystems similarly (e.g., oligotrophic and eutrophic), yet these categories are derived from different proxies. These inconsistencies in TS classification schemes may be compounded when interdisciplinary projects employ varied TS frameworks. Even with these shortcomings, TS can still be used to distill information on complex aquatic ecosystem function into a set of generalizable expectations. The usefulness of distilling complex information into a TS index is substantial such that usage inconsistencies should be explicitly addressed and resolved. To emphasize the consequences of diverging TS classification schemes, we present three case studies for which an improved understanding of the TS concept advances freshwater research, management efforts, and interdisciplinary collaboration. To increase clarity in TS, the aquatic sciences could benefit from including information about the proxy variables, ecosystem type, as well as the spatiotemporal domains used to classify TS. As the field of aquatic sciences expands and climatic irregularity increases, we highlight the importance of re-evaluating fundamental concepts, such as TS, to ensure their compatibility with evolving science.

期刊介绍: The scope of Ecosphere is as broad as the science of ecology itself. The journal welcomes submissions from all sub-disciplines of ecological science, as well as interdisciplinary studies relating to ecology. The journal''s goal is to provide a rapid-publication, online-only, open-access alternative to ESA''s other journals, while maintaining the rigorous standards of peer review for which ESA publications are renowned.
