Formalized classification of thermophilous oak forests in the Czech Republic : what brings the Cocktail method / Jan Rolecek in Preslia, vol. 79, n°1 (Année 2007)

It is based on the Cocktail algorithm, including the formulation of a set of explicit definitions of vegetation units that are used for unequivocal assignment of relevés to defined vegetation types. Eight out of 10 traditionally distinguished associations of thermophilous oak forests were formally defined: Bohemian warm and dry oak forest (Lathyro versicoloris-Quercetum pubescentis), Moravian warm and dry oak forest (Pruno mahaleb-Quercetum pubescentis), dry-mesic oak forest on basic rocky substrates (Corno-Quercetum), dry-mesic oak forest on acidic substrates (Sorbo torminalis-Quercetum), Moravian dry oak forest on acidic substrates (Genisto pilosae-Quercetum petraeae), dry-mesic oak forest on heavy soils (Potentillo albae-Quercetum), dry-mesic oak forest on sandy soils (Carici fritschii-Quercetum roboris) and dry oak forest on loess (Quercetum pubescentiroboris). The specific features of Cocktail classifications are discussed. The complementarity of the traditional, imperfectly formalized classifications and modern formalized classifications is stressed."

Modified TWINSPAN classification in which the hierarchy respects cluster heterogeneity / Jan Rolecek in Journal of Vegetation Science, vol. 20, n°4 (Année 2009)

Public [article]  inJournal of Vegetation Science > vol. 20, n°4 (Année 2009) . - pp. 596-602 Titre : Modified TWINSPAN classification in which the hierarchy respects cluster heterogeneity Type de document : texte imprimé Auteurs : Jan Rolecek, Auteur ; Lubomír Tichý, Auteur ; David Zeleny, Auteur ; Milan Chytrý, Auteur Année de publication : 2009 Article en page(s) : pp. 596-602 Langues : Anglais (eng) Résumé : "The proposed modification does not alter the logic of the TWINSPAN classification, but it may change the hierarchy of divisions in the final classification. Thus, unsubstantiated divisions of homogeneous clusters are prevented, and classifications with any number of terminal clusters can be created, which increases the flexibility of TWINSPAN."
