Plant functional traits and the multidimensional nature of species coexistence.
Understanding the processes maintaining species diversity is a central problem in ecology, with implications for the conservation and management of ecosystems. Although biologists often assume that trait differences between competitors promote diversity, empirical evidence connecting functional traits to the niche differences that stabilize species coexistence is rare. Obtaining such evidence i...
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...

Background & Aim: A herbarium is a collection of preserved plant specimens. Herbarium specimens form an important recorded of what plants grew where over time. Kerman province with area about 171993 km2 has a lat of difference vegetation because of climatic and topography variations. It has different elevation (above sea level) from 300 m in Shahdad to 4420 m in Hezar mountains. Mat...
