Fertilization effects on species density and primary productivity in herbaceous plant communities
Fertilization experiments in plant communities are often interpreted in the context of a hump-shaped relationship between species richness and productivity. We analyze results of fertilization experiments from seven terrestrial plant communities representing a productivity gradient (arctic and alpine tundra, two old-field habitats, desert, shortand tall-grass prairie) to determine if the respon...
متن کاملResponses of Herbaceous Species to Fire in Persian Oak (Quercus brantii) in Coppice Forests
Zagros forests are one of the important natural ecosystems in Iran with high plant diversity and variety of plant communities. In recent decades, fire events have frequently occurred in some of these ecosystems. The purpose of this research is to investigate the composition and diversity of herbaceous species after nine years of fire occurrence in the forests of Zagros in western Iran. For this...

متن کاملA REVISION OF PLANT-ASSOCIATED VERTICILLIUM SPECIES
Molecular approaches were used to re-evaluate the morphological criteria used to identify plant-associated Verticillium species. ITS-RFLPs divided the 31 studied strains of seven Verticillium species, (including the type species V. luteo-album) into four clusters. Cluster one comprised strains of the type species, V. luteo-album, cluster two V. albo-atrum, V. dahliae, V. nubilum and V. tricorpu...
متن کاملSpecies-specific response of photosynthesis to burning and nitrogen fertilization.
The present study was conducted to examine photosynthetic characteristics of three dominant grass species (Agropyron cristatum, Leymus chinensis, and Cleistogenes squarrosa) and their responses to burning and nitrogen fertilization in a semiarid grassland in northern China. Photosynthetic rate (P(n)), stomatal conductance (g(s)), and water use efficiency (WUE) showed strong temporal variability...
