PREMISE OF THE STUDY Expressed sequence tag-simple sequence repeat (EST-SSR) markers were developed using Illumina sequencing for further genetic diversity studies of Stipa purpurea (Poaceae). METHODS AND RESULTS Twenty-nine polymorphic and eight monomorphic EST-SSR loci were developed and characterized in 90 individuals from nine S. purpurea populations. The number of alleles per locus range...

Loss of plant diversity with increased anthropogenic nitrogen (N) deposition in 40 grasslands has occurred globally. In most cases, competitive exclusion driven by preemption of 41 light or space is invoked as a key mechanism. Here, we provide evidence from a 9-year N 42 addition experiment for an alternative mechanism: differential sensitivity of forbs and grasses to 43 increased soil manganes...

Flora and vegetation data of the nature monument regional importance “Elandinsky stones” (Tselinnyy district, Altai Krai) are given. comprises 283 species higher vascular plants, including 2 rare species: Paeonia hybrida, Stipa pennata. Vegetation is represented by petrophyte forb-feathergrass steppe, for Bijsk-Chumysh upland, forb-grasses meadow, birch forests bushes.

The population characteristic of the steppe species Stipa pennata, rare for South Ural State Nature Reserve, is given. Two coenopopulations (CP) European feather grass have been analyzed in western part reserve. ecotope conditions affected linear parameters plants significantly. weather year predetermined height generative shoot with a panicle and leaf length. maximum noted CP- 2, located relat...

In the present study, we aim to analyze the effect of grazing, precipitation and temperature on plant species dynamics in the typical steppe of Inner Mongolia, P.R. China. By uncoupling biotic and abiotic factors, we provide essential information on the main drivers determining species composition and species diversity. Effects of grazing by sheep were studied in a controlled experiment along a...
