Abstract The study was conducted on the Baraba plain in southern part of Western Siberia. Soil samples meadow ecosystems that are at different stages succession after drying lake bottom were analyzed. research allowed us to establish content soil organic matter and microbial biomass (the active matter) successional formed floodplain salt gradually increases last development reaches values zonal...

To date, no gene expression comparisons have been conducted between highly salt tolerant halophytes and related glycophytes. Therefore, I investigated the effects of salinity on ion accumulation and expression of candidate salt tolerance genes in the highly tolerant salt accumulating halophyte Salicornia dolichostachya and the taxonomically related glycophytic Spinacia oleracea. S. dolichostach...

Tropical coastal wetland ecosystems are widely distributed in arid regions. The Grande coastal lagoon in Peru’s central plain is shallow, eutrophic and alkaline, exposed to the annual hydrological regime with flooding and desiccation periods, when a salt crust is formed. The brackish to hypersaline habitats showed salinity gradients from 2-90 ppt (NaCl) to saturation, pH values from 7.0 to 10.5...

epizoochory and endozoochory are well-known mechanisms by which seeds are dispersed by animals. since, livestock gather around the watering-points to rest and drink, we expected to find that seeds would be frequently moved to the areas surrounding watering-points, resulting a higher soil seed density (and diversity) closest to the water. we investigated this issue by assessing soil seed bank de...
