“…This is the case when a natural area containing protected species is degraded for the needs of a human activity and a host site is sought for the implantation of these species so that their conservation status is not unduly altered (e.g. Cochlearia polonica , Cieślak et al., 2010). Sometimes, the project comes directly from a desire to reintroduce a taxon to a site from which it has disappeared or to reinforce an existing population.…”

Plant translocations in Europe and the Mediterranean: Geographical and climatic directions and distances from source to host sites

et al. 2021

Although the number of plant translocations has been rapidly increasing for two decades, no study is available to date that examines the directions and distances of plant displacements, which is essential (though not sufficient) information for considering translocations as a management tool to enable species to cope with the consequences of climate change. In this paper, we study the geographical and climatic directions and distances from source to host sites in 638 source‐and‐host site pairs of plant translocations that aimed to achieve viable populations in the last decades in the Western Palearctic (Europe and the Mediterranean). Translocation distances ranged from 0 to 661 km, but were generally short, most (82%) being <25 km, due to both ecological considerations and legal and administrative constraints. The host sites were not preferentially located in any geographical direction or in any altitude relative to the source sites. In contrast, on a climate compass constructed from a principal component analysis of seven bioclimatic variables, the host sites were slightly, but significantly, under colder climatic conditions than the source sites. This observation appears more to be the consequence of an effort to counteract already felt effects of climate change than to anticipate future changes. The climatic distance between source sites and actual host sites was generally smaller than between source sites and randomly selected host sites at a given distance or within a given geographical area, which may be the result of a desire to minimise climatic differences or differences in other ecological factors correlated with climatic differences. Synthesis. This study is the first to compare, geographically and climatically, the source sites of biological material and the host sites in translocations of wild plant species to obtain viable populations. Past translocations in the Western Palearctic are in line with mitigating the consequences of global warming on plant species because the host sites were in slightly cooler conditions than the source sites. Despite this, climate considerations seem to have little been taken into account in plant translocation projects and will certainly have to be much more so in a future with rapid anthropogenic climate change.

“…If the founder population does not develop rapidly, the persistence of a small number of individuals can also increase inbreeding in the population. A rapid increase in the abundance of a population can counteract the effect of inbreeding [42,63]. This can be observed in the Czech population, which is very abundant at present, having reached its current size as a result of regular conservation management.…”

“…Attributes such as life form, geographical range and breeding system influence the genetic structure of each species. Long-lived, perennial, widespread, outcrossing species generally show more genetic diversity than short-lived, selfing or mixed-mating, narrow endemic species [63,64]. Serratula lycopifolia is a long-lived perennial herb with a mixed-mating breeding system.…”

AFLPs were used to analyze the genetic variability of Serratula lycopifolia, one of the rarest plant species in Central and Western Europe, in six populations from the Wyżyna Małopolska upland (Poland), White Carpathian Mts (Slovakia and Czech Republic) and Podolian Upland (Ukraine). The results of polymorphism, PCoA and neighbor-net analyzes showed similar and relatively low genetic variation and high genetic similarity of individuals within each Polish population but there were differences between those populations. The population from Slovakia also showed comparatively high intrapopulation homogeneity and evident genetic separation from the other studied populations. Intrapopulation genetic variation was higher in the Czech and Ukrainian populations. However, AMOVA analyses revealed no significant differentiation at population and regional levels. The estimated low genetic diversity in the populations from Poland and Slovakia may be due to genetic processes such as genetic drift and inbreeding in local populations resulting from their low abundance, and does not seem characteristic of the species as a whole. These genetic analyzes make it clear that the Polish and Slovakian populations need support programmes to maintain their genetic variation. Measures should focus on increasing the number of individuals in the populations and on protecting their habitat

“…Separating most Cochlearia species fromIonopsidium is the coldness of their habitats (Koch, 2012). MostCochlearia species are already endangered, as suitable habitats have become increasingly rare, and two species have become extinct in the wild (Cochlearia polonica , Cieślak et al, 2007;Cieślak et al, 2010;C. macrorrhiza , Koch et al, 2003;Koch & Bernhardt, 2004).…”

Evolutionary footprints of cold adaptation in arctic-alpine Cochlearia (Brassicaceae) – evidence from freezing experiments and electrolyte leakage

As global warming progresses, plants may be forced to adapt to drastically changing environmental conditions. Arctic-alpine plants have been among the first to experience the effects of climate change, as regions at high latitudes and elevations are over-proportionally affected by rising temperatures. As a result, cold acclimation and freezing tolerance may become increasingly crucial for the survival of many plants as winter warming events and earlier snowmelt will cause increased exposure to occasional frost. Studying the evolution of cold adaptation allows us to make assumptions about the future responses of different species to climate change. The tribe Cochlearieae from the mustard family (Brassicaceae) offers an instructive system for studying cold adaptation in evolutionary terms, as the two sister genera Ionopsidium and Cochlearia are distributed among different ecological habitats throughout the European continent and the far north into circumarctic regions. By applying an electrolyte leakage assay to leaves, the freezing tolerance of different Ionopsidium and Cochlearia species was assessed by experimentally estimating lethal freezing temperature values (LT50 and LT100), thereby allowing for a comparison of different accessions in their responses to cold. We hypothesized that, owing to varying selection pressures, geographically distant species would differ in freezing tolerance. Despite Ionopsidium being adapted to hot and dry Mediterranean conditions and Cochlearia species preferring cold habitats, all accessions exhibited similar cold responses. Whether this phenomenon has resulted from an evolutionary adaptation of a common ancestor of the two taxa or has evolved from parallel evolution is yet to be investigated. The results presented in this study may, however, indicate that adaptations to different stressors, such as salinity and drought, may confer an additional tolerance to cold; this is because all these stressors induce osmotic challenges, as demonstrated via metabolomic analysis.
