功能性状越来越多地被用来了解植物的生态和预测它们对全球变化的反应。不幸的是，无法获得大多数植物物种的特征数据。缺乏特征数据对于难以测量的特征和热带植物物种来说尤其普遍，这可能是由于在偏远、高度多样化的雨林系统中处理物种的许多固有困难。植物园的活体收藏为人们提供了获取大量热带植物物种的便利途径，并有可能被用来快速扩大特征数据库，促进我们对物种对气候变化反应的理解。在这篇综述中，我们定量地评估了热带和温带物种的特征数据的可用性，几个示范热带植物园可供采样的物种的多样性，以及基于花园的叶和根特征测量的有效性。我们的分析支持这样的观点，即植物园的活标本是一种宝贵的科学资源，可以为植物功能生态学和保护的研究做出重大贡献。这篇文章是“了解人类世生物多样性的生物收藏”专题的一部分。
Functional traits are increasingly used to understand the ecology of plants and to predict their responses to global changes. Unfortunately, trait data are unavailable for the majority of plant species. The lack of trait data is especially prevalent for hard-to-measure traits and for tropical plant species, potentially owing to the many inherent difficulties of working with species in remote, hyperdiverse rainforest systems. The living collections of botanic gardens provide convenient access to large numbers of tropical plant species and can potentially be used to quickly augment trait databases and advance our understanding of species' responses to climate change. In this review, we quantitatively assess the availability of trait data for tropical versus temperate species, the diversity of species available for sampling in several exemplar tropical botanic gardens and the validity of garden-based leaf and root trait measurements. Our analyses support the contention that the living collections of botanic gardens are a valuable scientific resource that can contribute significantly to research on plant functional ecology and conservation. This article is part of the theme issue ‘Biological collections for understanding biodiversity in the Anthropocene’.
