From: At which spatial scale are plant species composition and diversity affected in beech forests?
Principal component analysis results for plant species distribution. Axes 1–2, bi-plot of plant species and three principal groups of species created on the basis of the two main factors determining species distribution (axis 1, proportion of Quercus spp. forest surrounding beech forest plots (% Quercus around); axis 2, soil pH). The abbreviations correspond to the species: Acer A. campestre, Fagus F. sylvatica, Fraxinus F. excelsior, Q.faginea Q. faginea, Q.robur Q. robur, S.aria S. aria, S.aucuparia S. aucuparia, Cornus C. sanguinea, Corylus C. avellana, C.laevigata C. laevigata, C.monogyna C. monogyna, Erica E. vagans, Hedera H. helix, Ilex I. aquifolium, Lonicera L. periclymenum; Prunus P. spinosa; Rosasp Rosa spp., Rubussp Rubus spp., Ruscus R. aculeatus, Tamus T. communis, Vaccinium V. myrtillus, Ajuga A. reptans, Anemone A. nemorosa, Carex C. sylvatica, Cruciata C. glabra, Deschampsia D. flexuosa, E.amygdaloides E. amygdaloides, E.dulcis E. dulcis, Galium G. odoratum, Helleborus H. viridis, Hepatica H. nobilis, Lamium L. galeobdolon, Lathyrus L. linifolius, Merculiaris M. perennis, Oxalis O. acetosella, P.erecta P. erecta, P.montana P. montana, P.sterilis P. sterilis, Ranunculus R. tuberosus, Sanicula S. europaea, Saxifraga S. hirsuta, Scilla S. lilio-hyacinthus, Stachys S. officinalis, Stellaria S. holostea, Symphytum S. tuberosum, Taraxacum T. officinale, V.montana V. montana, V.officinalis V. officinalis, Vicia V. sepium, Viola V. riviniana, Gramíneas Gramineae, Athryrium A. filix-femina, Blechnum B. spicant, Dryopteris D. affinis, Pteridium P. aquilinum
