“…genealogical continuity) of woody plants at a specific site since the arrival of the species after post-glacial remigration. (KLEINSCHMIT et al, 2004). In comparison, the term native denotes that the growing site is a part of the natural geographic range of the species, and does not automatically imply local adaptation.…”

“…Lower in the taxonomic hierarchy, genetic diversity is a necessary means of survival in dynamic ecological equilibria. Long-lived tree and shrub species need to maintain their genetic diversity in order to ensure that their progeny can remain well adapted to complex heterogeneous environments (BEHM et al, 1997, KLEINSCHMIT et al, 2004.…”

“…Ideally, regions of provenance are defined according to ecological growing conditions, genetic variability between the natural populations of the tree and shrub species and information on adaptation and adaptability, which can be deduced in part from provenance trials (KLEINSCHMIT et al, 2004). For most species in Flanders there is no information on the latter two subjects.…”

“…There is an urgent need to define scientifically based seed transfer zones. Information is necessary on aspects of adaptation and adaptability, to be obtained through provenance trials that include local provenances and through research on introgression between locally adapted and non-autochthonous genotypes (KLEINSCHMIT et al, 2004). It is clear that research employing routinely applied neutral molecular markers is helpful in informing genetic conservation efforts (e.g.…”

Conservation Approaches For Autochthonous Woody Plants in Flanders

Autochthonous genetic resources of woody plants have become seriously endangered in Flanders because of the particularly low and fragmented forest cover, centuries of intensive forest use in this highly populated area and the wide-spread usage of non-autochthonous planting stock in reforestation and landscape plantings. Intraspecific hybridisation between remnant autochthonous populations and foreign genotypes, which can show inadequate adaptation, may influence the autochthonous genetic constitution and fitness in the long term. As several European countries face similar problems, the objective of this paper is to outline the conservation measures that are taken in Flanders. The central aim is to maintain and create the necessary conditions for natural and flexible evolution of the genetic diversity of autochthonous trees and shrubs. An inventory survey to locate remaining autochthonous populations was started in 1997 and will be completed in 2006. Relict populations are preserved in clonal banks. Central issues are the production of autochthonous planting stock through in situ seed collection, the approval of seed sources and stands and the creation of seed orchards. Conservation actions are discussed.

“…There is a significant mass of literature about the most commonly applied methods for delimiting Regions of Provenance according to the factors mentioned above (e.g. Geburek & Konrad, 2008;Kleinschmit et al, 2004;Lindgren & Ying, 2000;Krusche & Geburek, 1991;Raymond & Lindgren, 1990). They usually refer to the division of the territory (divisive method), if ecological parameters are considered, instead of joining of similar populations (agglomerative method) according to common biological features.…”

Evidence for genetic differentiation and divergent selection in an autotetraploid forage grass (Arrhenatherum elatius)

et al. 2010

The use of local provenances in restoration, agriculture and forestry has been identified as measure to sustain biological diversity and to improve local productivity. However, the delineation of regional provenances is challenging because it requires the identification of well-defined groups based on spatiogenetic differentiation and/or the evidence of local adaptation. In this study, we investigate genetic variation at 186 AFLP loci in 46 European accessions of the important grassland species Arrhenatherum elatius and ask (1) whether genetic variation within accessions differs between European geographical regions; (2) at which spatial scale populations are structured across Europe and (3) whether putatively adaptive markers contribute to this pattern and whether these markers can be related to climatic site conditions. Basic expectations of population genetics are likely to be altered in autotetraploid species, thus, we adopted a band-based approach to estimate genetic diversity and structuring. Compared to other grasses A. elatius showed high genetic diversity and considerable differentiation among accessions (Phi(ST) = 0.24). Accessions separated in a Western European and a Central/Eastern European group, without further structure within groups. A genome scan approach identified four potentially adaptive loci, whose band frequencies correlated significantly with climatic parameters, suggesting that genetic differentiation in A. elatius is also the result of adaptive processes. Knowledge on adaptive loci might in the long run also help to adapt ecosystems to adverse climate change effects through assisted migration of ecotypes rather than introduction of new species.
