“…The similarity of the two Biebrza populations suggests their common origin and ongoing gene exchange. Other orchids investigated in northeast Poland present a similar situation (Brzosko, Wróblewska & Tałałaj, 2004; Brzosko et al ., 2009, 2011).…”

“…The influence of mating between relatives on the genetic variation of N. ovata populations is strictly connected with their small size, especially in the context of effective population size (Whitlock, 2000). Many empirical studies have shown that smaller populations have lower genetic variation (Young, Boyle & Brown, 1996;Frankham, Ballou & Briscoe, 2003;Brzosko et al, 2011), and the main factor behind this is genetic drift. Small population size is a common characteristic of the populations studied and, presumably, it was an important factor in their decreased levels of genetic and genotypic variation.…”

Using 32 allozyme loci, we examined the genetic diversity of ten populations of Neottia ovata differing in size and located in different regions of northeast Poland. Within‐population genetic variation was low (Ppl = 9.4–31.2%, A = 1.09–1.34 and HE = 0.044–0.128) relative to taxa with similar life histories. In the majority of N. ovata populations (excluding those in Biebrza), we noted high genotypic diversity (0.49−1.00) and high proportions of unique genotypes (86–100%). Neottia ovata shows a strong pattern of genetic differentiation among populations in northeast Poland, reflected in the high overall FST value (0.409). There was a weak, but significant, relationship between genetic and geographical distance (r = 0.09, P < 0.05). We discuss the breeding system, small population sizes and population subdivision as the most important factors affecting the genetic diversity of this species. © 2012 The Linnean Society of London, Botanical Journal of the Linnean Society, 2012, 170, 40–49

“…Fragmentation among its populations at varying level of severity was observed in some countries but this process was not regarded as a major threat to the species (Rankou and Bilz 2014), mainly due to its wide distribution. Results of previous genetic studies on C. calceolus showed relatively high levels of polymorphism and clonal diversity as well as low or moderate levels of population differentiation (Kull and Paaver 1997;Brzosko et al 2002Brzosko et al , 2009Brzosko et al , 2011Gargiulo et al 2018), which may support the claim that fragmentation has little effect on C. calceolus. However, authors attributed these features to persistence of residual diversity when the species had a more continuous distribution and pointed out that observed population differentiation may also be fragmentation related (Kull and Paaver 1997;Brzosko et al 2011).…”

Spatial genetic structure of an endangered orchid Cypripedium calceolus (Orchidaceae) at a regional scale: limited gene flow in a fragmented landscape

et al. 2018

Plant species that are capable of propagating clonally are expected to be less vulnerable to habitat fragmentation due to their long life span. Cypripedium calceolus L. is a rare, clonal, long-lived orchid species. It has suffered marked decline because of habitat loss and fragmentation and over-collection, yet an IUCN report on this species does not regard fragmentation as a major threat to the species. We applied 13 nuclear microsatellites and cpDNA sequences to identify the patterns of population structure, genetic diversity and connectivity of six remnant local populations of C. calceolus in highly fragmented Gdańsk Pomerania region (N Poland). Despite severe (80%) loss of localities in the studied area we found that the local populations retain high levels of clonal (R 0.86-1) and genetic diversity (H e = 0.572). However, their differentiation is relatively high (F ST = 0.132 for nuclear SSR and F ST = 0.363 for cpDNA) despite close geographic proximity (0.6-57 km). Bayesian clustering classified populations according to their geographic origin with little admixture. Low genetic connectivity between the remnant populations shows that the current gene flow is too low to serve as a cohesive force in a fragmented habitat, which may impede a quick response to environmental change. The species' ability to retain ancestral variation may help withstand fragmentation, but in the light of observed extirpation rate it should be rather considered as a factor that only delays local populations' extinction. This leads to the conclusion that habitat loss and fragmentation should be regarded as a real threat to stability of C. calcelolus populations.

“…In different regions of Eurasia, C. calceolus has been estimated as Near Threatened (Bilz 2011, Turis et al 2014, Vulnerable (Rassi et al 2001), Endangered (Witkowski et al 2003), and Critically Endangered (Blinova & Uotila 2011, Khapugin et al 2017a, Khapugin et al 2017c.

Cypripedium calceolus (Orchidaceae) in Central Russia: a case study for its populations in two protected areas in the Republic of Mordovia (Russia)

AbstrACt. Cypripedium calceolus is considered as one of the flagship plant species of nature conservation. It is legally protected throughout Eurasia. Due to its wide distribution range, this Eurasian species could be considered as Least Concern, Near Threatened, Vulnerable, Endangered or Critically Endangered taxon. We performed an analysis of the status for some C. calceolus populations in Central Russia located in the Republic of Mordovia, with emphasis on populations situated in the federal protected areas. The aim of our study was to asses the modern state and the endangerment of C. calceolus populations. The environment conditions and species composition in five habitats with rare species in Mordovia were compared using phytoindication methods. Changes in stage spectrum and total abundance dynamics in C. calceolus populations over 2011-2016 were estimated and compared with available data from other locations within species' range. Reproductive ability of populations from the federal protected area, Mordovia State Nature Reserve, were studied. The results showed that C. calceolus grows in three habitat types that differed in environment conditions and floristic composition. Convallaria majalis was the only species registered in all studied locations, together with C. calceolus. In Central Russia this species occurs in broad-leaved, coniferous and mixed forests. The three populations of C. calceolus within the Mordovia State Nature Reserve and National Park "Smolny" were characterized by the dominance of vegetative individuals in stage spectrum, while generative plants predominated in two other populations located in mixed forests. No correlation between total abundance of individuals and stage spectrum in populations of threatened species has been found over the study period. The population in Mordovia Reserve showed a higher fruit set (36.7% as a mean) than others reported within its range. Continued population monitoring of C. calceolus in Central Russia from different habitat types is suggested. Generalization of jointly obtained demographic, ecological, phytocoenological data will be appropriate in order to develop measures for conservation and management of C. calceolus habitats.
