“…Numerous subsequent studies have also found low genetic differentiation among orchid populations (for example, Chung et al, 2005;Esfeld et al, 2008;Swarts et al, 2009). Self-fertilization may contribute to the high differentiation of I. medeoloides populations (Hamrick and Godt, 1996), although Neotina maculata, another selfing orchid species, has low population differentiation (Duffy et al, 2009).…”

Highest genetic diversity at the northern range limit of the rare orchid Isotria medeoloides

Populations in previously glaciated regions are often genetically depauperate in comparison with populations at lower latitudes, due either to bottlenecks experienced in post-glacial colonization or to contemporary genetic drift in small, peripheral populations. Populations of the rare self-fertilizing North American orchid Isotria medeoloides are largest in the previously glaciated region near the northern range limit, allowing us to examine the role of historical versus contemporary processes in determining population genetic diversity and structure. If contemporary processes predominate, genetic diversity should increase with increasing census size. In contrast, if sequential bottlenecks associated with colonization are paramount, diversity should decrease with latitude and be relatively insensitive to census size. We genotyped 299 individuals from 20 populations at four variable microsatellite loci to contrast genetic diversity and structure for populations in previously glaciated regions versus previously unglaciated regions. Populations were highly inbred (F ¼ 0.95) and highly differentiated (R ST ¼ 0.485). Across all sampled populations, genetic diversity decreased and genetic differentiation increased with declining population size. Small southern populations were especially differentiated and genetically depauperate. In the glaciated part of the range, genetic diversity increased as populations approached the northern range limit, demonstrating the centrality of contemporary processes for this post-glacial colonist.

“…In the humus substratum only, in the favorable climate under the trees there were forest species strictly protected by the Polish law: Epipactis atrorubens, E. helleborine as well as the partially protected Frangula alnus. Plant patches near the forest with rare species of orchids occurred also on the most advanced succession stages in post-mining dumps in the Upper Silesia Coalfield (CABA£A and SYPIEÑ 1987, CABA£A and JARZ¥BEK 1999, ROSTAÑSKI 2006), Lower Silesia Coalfield (KUCZYÑSKAet al 1984, as well as in post-mining dumps in England and Germany (ASH et al 1994, ESFELD et al 2008). …”

-The aim of the present study was to investigate the composition of spontaneous plant cover and the physicochemical properties of the substratum of spoil heaps of the Siersza hard coal mine in Trzebinia (southern Poland) abandoned in 2001. Floristic and soil analyses were performed in 2011. The substratum was very diverse in terms of texture (sand: 55-92 %, clay: 6-38 %), nutrient content (total C: 1.3-41.0 %, total N: 0.05-0.49 %, total Ca: 0.5-7.3 %) and pH (3.7-8.7). Moreover, total thallium concentration in the substratum was high, ranging from 6.0 to 14.6 mg kg -1 . Plant cover varied from 50 to 95 %. The number of plant species per 4 m 2 varied from 6 to 29 and correlated negatively with total carbon content (r = -0.85, p < 0.01), and positively with sand content in the substratum (r = 66, p < 0.05). The highest number of species per area unit was observed on a humus substratum, where initial soil has developed on the part of carboniferous waste rock spoil under 20-30 year old trees, and the lowest on carbon shale with coal and culm. Among 197 plant species, most belong to Asteraceae, Fabaceae, Poaceae and Rosaceae families. Hemicryptophytes (49%) and terophytes (18%) predominated. The investigated area was primarily colonized by native species spread by the wind. However, invasive alien species also had a significant share (8%) in the plant cover.

“…However, disturbed habitats could also function as a refuge for rare and endangered plants (Greenwood and Gemmell, 1978;Heindl and Ullmann, 1991;Ullmann et al, 1998;Brändle et al, 2003;Nowak, 2005Nowak, , 2006Esfeld et al, 2008;Kirpluk and Bomanowska, 2008;Reisch, 2006;van Kleef et al, 2012;Zielińska et al, 2016). Surprisingly, orchids are often found in the apophytes group, but they are still one of the most threatened plant groups in the world (Sharrock and Jones, 2009;Bliz et al, 2011;The IUCN Red List of Threatened Species 2015).…”

Many species from the family Orchidaceae spread in anthropogenic habitats and numerous studies documenting this process are known. Unfortunately, such data are scattered throughout various papers and reports, sometimes fragmentary and hard to reach (the 'grey literature'). Scientific elaboration on this topic still lacks a comprehensive review and summary of the scale of this phenomenon. Therefore, the main aim of this study was to gather, review and analyse such data, seeking the answer to the question whether the man-made habitats can be considered as refugee for orchids. The paper summarises data on the occurrence of orchid species in man-made habitats in Europe originating from published and unpublished sources. The particular emphasis was placed in urban habitats. For this purpose, the floristically data from 42 European cities were used. The conducted studies showed that the apohytism phenomenon in the family Orchidaceae was more widespread than had been previously reported. As a result, 70 species of orchids in the distinguished man-made habitats were found. The majority of the species grow on sand and clay pits. The most common species were Epipactis helleborine and Dactylorhiza majalis. The gathered data have confirmed that man-made habitats become refugee for many orchid species in the aftermath of the loss of their natural habitats. Thus, protection of sites transformed by man with orchid occurrence should be taken into consideration. These sites can become a source of very useful information for biogeographically and phylo-geographically analyses of many valuable and endangered species.
