摘要

目前,由于全球气候变化,我们正在观察到物种的巨大损失。迁地保护提供了一个重要的工具来抵消物种的损失,从而有助于维持生物多样性。本文以捷克特有的濒危蛇形植物mejkalii为研究对象,建立了一个包括19个私人花园和2个植物园的非原生境保护系统。为了在花园中创造合适的栖息地,人造蛇形土丘将自然场地的土壤与附近采石场的蛇形岩石和砾石结合在一起。我们调查了在迁地保护地点的植物与在自然生境中生长的植物的表现,以及这些人工地点在多大程度上代表了自然地点的条件。我们利用植物的功能性状,包括叶丛直径、叶绿素荧光、叶绿素含量和比叶面积(SLA)来评估植物的性能。研究发现,尽管非生物因素(温度、土壤性质和遮阳)与自然条件不完全匹配,在非生境条件下植物死亡率较高、生长性能较低,但我们仍成功地创造了许多独立的史氏芽孢杆菌种群,并增加了其植物功能性状的变异性,这可能有利于其生存。利用私人花园作为移地保护地点,通过当地社区和园丁的参与,也有助于提高对史米卡利米保护的认识,因此,这被证明是一种有用而有力的植物保护技术。

Using private gardens to conserve Minuartia smejkalii - a novel approach for ex situ conservation
We currently observe a tremendous loss of species due to the ongoing global change. Ex situ conservation provides an important tool to counteract species losses and thus helps to maintain biodiversity. Here, we present a setup which involves 19 private gardens and 2 botanical gardens as sites of ex situ conservation using Minuartia smejkalii, an endangered serpentinophyte endemic to Czechia as a case study. To create suitable habitats in the gardens, artificial serpentine mounds were built, combining soil from natural sites with serpentine rocks and gravel from nearby quarries. We investigated how the plants performed at ex situ conservation sites compared with plants growing in natural habitats and how well these artificial sites represented the conditions at the natural sites. We assessed plant performance using plant functional traits including tuft diameter, chlorophyll fluorescence, chlorophyll content, and specific leaf area (SLA). We found that even though abiotic factors of the ex situ conservation sites (temperature, soil properties and shading) did not entirely match the natural conditions and plant mortality was higher and performance lower under ex situ conditions, we managed to create many independent M. smejkalii populations and increase its variability in plant functional traits, which might facilitate its survival. Using private gardens as ex situ conservation sites also helped to raise awareness on the conservation of M. smejkalii through engagement of the local community and the gardeners and thus, this proves to be a useful and powerful technique in plant conservation.

期刊介绍: Biological Conservation is an international leading journal in the discipline of conservation biology. The journal publishes articles spanning a diverse range of fields that contribute to the biological, sociological, and economic dimensions of conservation and natural resource management. The primary aim of Biological Conservation is the publication of high-quality papers that advance the science and practice of conservation, or which demonstrate the application of conservation principles for natural resource management and policy. Therefore it will be of interest to a broad international readership.
