the effect of soil and phanerogam characteristics on bryophytes composition, richness, abundance and functional groups were investigated in order to understand the factors responsible for bryophytes distribution patterns. three different sand dunes were selected: untouched, artificial sod-covered and planted by ammophila. along 10 transects perpendicular to the shore, a total of 142 permanent r...

I develop a factor content of trade prediction for the Heckscher-OhlinVanek model (HOV) that relates bilateral differences in country endowments to bilateral differences in factor contents. The results are striking. In comparisons of North-South factor contents or factor contents of countries with very different endowments (e.g., with very different capital-labor ratios), there is clear support...

the morphological diversity of arbuscular mycorrhizal fungi (amf) at the anguran zn and pb mining region (zanjan province, iran) were studied along a transect from the mine to 4500 m away. within each plot, a composite sample of root and rhizospheric soil from a dominant indigenous plant was collected. the soil samples were analyzed for their physico-chemical characteristics. spores were extrac...
