Phenotypic variation of the rare species Cephalaria uralensis (Murr.) Schrad. ex Roem. et Schult. in the Republic of Bashkortostan, the Southern Urals

Phenotypic variation of the rare species Cephalaria uralensis (Murr.) Schrad. ex Roem. et Schult.... Variation in morphometric parameters of the poorly studied rare species Cephalaria uralensis (Murr.) Schrad. ex Roem. et Schult. has been studied at the northern boundary of its range, in the Southern Urals (Bashkortostan). The species in the region grows in four types of steppe communities of the class Festuco-Brometea. Variation in the majority of parameters is within the species reaction norm. The most variable parameters are the numbers of vegetative and generative shoots and the number of inflorescences per shoot. As shown by discriminant analysis, all 16 cenopopulations included in the study significantly differ from each other (Wilks’ λ = 0.21), with most of them being morphologically and structurally uniform. The state of local C. uralensis appears to be satisfactory, and this species is not at serious risk for extinction in the territory of Bashkortostan. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Ecology Springer Journals

Abstract

Variation in morphometric parameters of the poorly studied rare species Cephalaria uralensis (Murr.) Schrad. ex Roem. et Schult. has been studied at the northern boundary of its range, in the Southern Urals (Bashkortostan). The species in the region grows in four types of steppe communities of the class Festuco-Brometea. Variation in the majority of parameters is within the species reaction norm. The most variable parameters are the numbers of vegetative and generative shoots and the number of inflorescences per shoot. As shown by discriminant analysis, all 16 cenopopulations included in the study significantly differ from each other (Wilks’ λ = 0.21), with most of them being morphologically and structurally uniform. The state of local C. uralensis appears to be satisfactory, and this species is not at serious risk for extinction in the territory of Bashkortostan.
