摘要

虽然核对表是管理和保护超基性岩生态系统的重要工具,但目前还没有伊比利亚半岛南部超基性岩生态系统的最新核对表。因此,我们的研究目标是:(1)创建伊比利亚半岛南部蛇龙科植物的最新核对表;(2)确定蛇龙科植物的分布是否与某些特定类型的超基性岩有关;(3)计算每个露头蛇龙科植物的丰度和丰富度,以指导保护工作。通过实地考察、检索文献和标本馆等方法,我们编制了一份包含 28 种蛇皮属植物(即 23 种必生类群、1 种优先类群、1 种亚蛇皮属植物和 3 种地区性蛇皮属植物)的更新核对表。蛇床子属植物显示出不同的岩石亲和性,其中哈氏白云母-蛭石和哈氏白云母-辉石-云母的占有率较高,这可能是由于它们的矿物学和化学成分(如含有重金属)和/或这些露头的表面积较大。我们还观察到,21 个物种在不同岩相实体中的占有率较高,其原因可通过未来的土壤分析加以阐明。在贝尔梅哈的主要岩层中,蛇形植物的丰富度最高,其次是阿尔普贾塔、阿瓜斯和瓜达尔霍斯山谷的较小岩层。虽然阿瓜斯的蛇龙科植物丰富程度与阿尔普贾塔相似,但由于生物气候和生物地理上的隔离,阿瓜斯的一些地区出现了明显的差异。鉴于伊比利亚半岛南部仅有蛇形植物区系,伊比利亚半岛南部的所有露头地区都应受到某种形式的保护,成为受保护的自然空间。

An updated checklist of serpentinophytes for research and conservation in ultramafic ecosystems on the southern Iberian Peninsula (Spain)

An updated checklist of serpentinophytes for research and conservation in ultramafic ecosystems on the southern Iberian Peninsula (Spain)

Although checklists are essential tools for managing and conserving ultramafic ecosystems, no updated checklist currently exists for ultramafic ecosystems on the southern Iberian Peninsula. Thus, the objectives of our study were (1) to create an updated checklist of serpentinophytes on southern Iberian Peninsula, (2) to determine whether the distribution of serpentinophytes is associated with certain specific types of ultramafic rocks, and (3) to calculate the abundance and richness of serpentinophytes per outcrop to guide conservation efforts. Following a methodology involving field work and searches of bibliographies and herbaria we produced an updated checklist containing 28 serpentinophytes (i.e., 23 obligates, one preferential taxon, one sub-serpentinophyte, and three regional serpentinophytes). The serpentinophytes showed different petrological affinity, where harzburgite–lherzolite and harzburgite–pyroxenite–dunite exhibited higher occupancy, possibly due to their mineralogical and chemical composition (e.g., containing heavy metals) and/or the larger surface area of those outcrops. We also observed that the occupancy of 21 species was higher in different petrographic entities, the reasons for which could be elucidated by future soil analyses. The highest richness of serpentinophytes was found in the main outcrop of Bermeja, followed by smaller outcrops of Alpujata, Aguas, and Guadalhorce Valley. Although the richness of Aguas resembled that of Alpujata, a notable difference emerged in some of its areas owing to bioclimatic and biogeographic isolation. Given the exclusive presence of serpentinophyte flora on the southern Iberian Peninsula, all southern Iberian outcrops should receive some form of conservation as protected natural spaces.
