摘要

摘要:在中欧,根据不同地区的不同,白三叶草被认为是容易灭绝、受到严重威胁甚至灭绝的物种。近年来,这种罕见的兰花在其自然范围内的数量明显增加。该研究的目的是提供关于波兰南部环北方物种大量存在的新数据(地点位置、估计标本数量、栖息地数据),以表明其生态扩张。用地形图方法描述了白三叶的位置,然后用cartogram方法显示了其分布。该研究于2010年至2018年在西维托克日斯基山脉(波兰南部)西南部进行,面积337,5平方公里。在研究过程中,首次在11个地点发现了该物种。在次生松林中观察到最大的种群。这项研究的结果以公布的数据为背景,表明该物种在波兰的生态扩张是由合适的栖息地促进的。在全球变暖的背景下,这种适应寒冷的物种的扩张是有趣的。

Expansion of Cold-Adapted Orchid Goodyera repens (Orchidaceae) in Times of Global Warming – Report from Southern Poland
ABSTRACT In Central Europe Goodyera repens (L.) R. Br. is considered as species vulnerable to extinction, critically threatened, or even extinct, depending on the region. In recent years, this rare orchid clearly increases the number of sites within its natural range. The aim of the study is to present new data on the abundant occurrence of circum-boreal species in southern Poland (position of localities, the estimated number of specimens, habitat data) that indicate its ecological expansion. The localities of G. repens were described using the topogram method and then its distribution was shown using cartogram method. The study was conducted in the years 2010–2018 in the south-western part of the Świętokrzyskie Mountains (S Poland) on the area of 337,5 km2. During the study the species was found for the first time on eleven localities. The largest populations were observed in secondary pine forests. The results of this study against the background of published data suggest the ecological expansion of the species in Poland, which is facilitated by the availability of suitable habitats. The expansion of this cold-adapted species is interesting in the context of the global warming.
