ABSTRACT Introduction: The Alps are one of the richest biodiversity ‘hot spots’ in Europe, but also one of the most threatened in the context of climate change. Here, we report the results of a long-term survey of the bryophyte flora of Queyras, a high-altitude limestone area, which can serve as baseline data to document and monitor the flora of this poorly-known area. Methods: Bryophyte distribution data were collected in the course of six field trips between 1981 and 2017. The dataset includes 6890 observations in 154 1 km2 MGRS gridsquares. Key results: The bryophyte flora of Queyras includes 500 species, of which 34% are newly reported here and 8% were previously reported but not seen in the course of the present survey. For each species, distribution maps at the level of 1 km2 MGRS gridsquares, frequency, and elevation range are reported. Queyras includes ten species of high conservation relevance in Europe, namely the liverworts Mannia fragrans and Riccia breidleri and the mosses Didymodon glaucus, Grimmia mollis, Hygrohypnum styriacum, Molendoa hornschuchiana, Orthotrichum crenulatum, Platyhypnum molle, Schistidium grande and Tayloria acuminata. Conclusions: Our study illustrates the extent to which the bryophyte flora of even such noteworthy botanical places as Queyras is extremely rich and holds a substantial proportion of species of high conservation relevance at the European level, but is poorly documented, calling for a substantial effort aiming at inventorying, mapping and protecting the unique bryophyte flora of the Alps.

高山石灰岩地区的苔藓植物区系(法国上阿尔卑斯省 Queyras)

摘要 介绍:阿尔卑斯山是欧洲生物多样性最丰富的“热点”之一,也是气候变化背景下最受威胁的地区之一。在这里,我们报告了对高海拔石灰岩地区 Queyras 苔藓植物区系进行的长期调查的结果,这些结果可以作为基线数据来记录和监测这个鲜为人知的地区的植物区系。方法:苔藓植物分布数据是在 1981 年至 2017 年期间的 6 次实地考察中收集的。该数据集包括 154 个 1 平方公里 MGRS 网格中的 6890 个观测值。主要结果:奎拉斯苔藓植物区系包括 500 种,其中 34% 是这里新报告的,8% 以前报告过但在本次调查过程中未发现。对于每个物种,报告了 1 平方公里 MGRS 网格方格、频率和高程范围级别的分布图。Queyras 包括 10 种在欧洲具有高度保护相关性的物种,即地草 Mannia fragrans 和 Riccia breidleri 以及苔藓 Didymodon glaucus、Grimmia mollis、Hygrohypnum styriacum、Molendoa hornschuchiana、Orthotrichum crenulatum、Platyhypnum molle 和 Schistidia a Taylor。结论:我们的研究表明,即使是像 Queyras 这样值得注意的植物区,苔藓植物区系也极其丰富,并且在欧洲层面上拥有相当大比例的具有高度保护相关性的物种,但记录不足,需要付出大量努力在清点、测绘和保护阿尔卑斯山独特的苔藓植物群。即地草 Mannia fragrans 和 Riccia breidleri 以及苔藓 Didymodon glaucus、Grimmia mollis、Hygrohypnum styriacum、Molendoa hornschuchiana、Orthotrichum crenulatum、Platyhypnum molle、Schisidium grande 和 Tayloria acuminata。结论:我们的研究表明,即使是像 Queyras 这样值得注意的植物区,苔藓植物区系也极其丰富,并且在欧洲层面上拥有相当大比例的具有高度保护相关性的物种,但记录不足,需要付出大量努力在清点、测绘和保护阿尔卑斯山独特的苔藓植物群。即地草 Mannia fragrans 和 Riccia breidleri 以及苔藓 Didymodon glaucus、Grimmia mollis、Hygrohypnum styriacum、Molendoa hornschuchiana、Orthotrichum crenulatum、Platyhypnum molle、Schisidium grande 和 Tayloria acuminata。结论:我们的研究表明,即使是像 Queyras 这样值得注意的植物区,苔藓植物群也极其丰富,并且在欧洲层面上拥有相当大比例的具有高度保护相关性的物种,但记录不足,需要付出大量努力在清点、测绘和保护阿尔卑斯山独特的苔藓植物群。
