In drylands, primary production is predominantly limited by water availability; however, there is evidence for co-limitation by nutrients. We tested whether improved water and nutrient availability facilitate reproduction of dominant steppe species, and studied the effects of increased moisture and fertilization on seed production of the steppe grass Stipa krylovii.Effects of water availability on...
The present paper describes the anemochorous dispersal of representative diaspores of Asteraceae, Dipsacaceae, and Poaceae from xerothermic grassland communities of Central and Northeastern Germany. For eleven species, potential dispersal distance was determined by fall velocity experiments as well as by taking into account the diaspore flight angle under the influence of an artificially-produced,...
