宽口立碗藓在欧洲很罕见,濒临灭绝。本研究调查了其在英国的地位和生态。对P.在英国所有有报道的地点,以及附近的其他四个地点。殖民地的地理坐标记录与全球定位系统的单位,并用于推导出占用的OrphonySurvey(OS)的网格单元在1,10和100米的分辨率计数。 DNA条形码用于帮助识别非结果植物。栖息地和群落组成记录relevés.结果.宽口立碗藓分布于赫特福德郡和西诺福克的5个地点,共占据109个1 m网格细胞。 西诺福克的一个小池塘(Wyndham Pond)支持大多数人(61%)。DNA条形码帮助确认了它在Wilstone水库(赫特福德郡)的存在,它被认为已经灭绝了。苔藓只发生在季节性波动的淡水水体,自然和人工的水位下降区。植被以维管植物为主,常见的有匍匐剪股颖、石龙芮、石龙芮、沼泽地菜和繁缕。土壤pH值从强酸性到弱碱性变化。对五个有历史记录的地点的搜索失败引起了对该物种的关注。Wessel Pond的重要性以前没有得到承认,并建议对该网站进行法定保护。外来入侵的厚壳厚壳是对P.分布在英国和欧洲其他地方的广口蚁群
Introduction.Physcomitrium eurystomumis rare in Europe and threatened with extinction. This study investigates its status and ecology in Britain.Methods. A detailed search was made forP. eurystomumat all sites where it has been reported in Britain, plus four other locations nearby. Geographic coordinates of colonies were recorded with GPS units and used to derive counts of occupied Ordnance Survey (OS) grid cells at resolutions of 1, 10 and 100 m. DNA barcoding was used to help identify non-fruiting plants. Habitat and community composition were recorded by relevés.Results. In this studyPhyscomitrium eurystomumwas found at five locations, one in Hertfordshire and four in West Norfolk, and occupied 109 OS 1 m grid cells. A small pond in West Norfolk (Wicken Pond) supported the majority (61%) of the population. DNA barcoding helped confirm its occurrence at Wilstone Reservoir (Hertfordshire), at which it was thought extinct. The moss occured exclusively within the drawdown zone of seasonally fluctuating freshwater bodies, both natural and artificial. Vegetation was dominated by vascular plants, most frequentlyAgrostis stolonifera, Persicaria lapathifolia, Ranunculus sceleratus, Rorippa palustrisandStellaria aquatica. Soil pH varied from strongly acidic to slightly alkaline.Conclusions. Unsuccessful searches of five sites with historic records raises concern for the species. The significant importance of Wicken Pond has not been recognised previously and suggests statutory protection of the site is warranted. The non-native and invasiveCrassula helmsiiis a major risk toP. eurystomumat sites in Britain and elsewhere in Europe.
