heavy metals in high concentrations in soils are potential health risk for humans, animals, and plants. soil samples were collected in five replicates from 20 points with four land use including: roads, refineries, residential area (sadra town), and farmland. heavy metals were determined using flame atomic absorption (analyticjena), while dtpa was chosen as trace elements extractor. in this stu...

Land-use change is considered likely to be one of main drivers of biodiversity changes in grassland ecosystems. To gain insight into the impact of land use on the underlying soil bacterial communities, we aimed at determining the effects of agricultural management, along with seasonal variations, on soil bacterial community in a Mediterranean ecosystem where different land-use and plant cover t...

Abstract The phenomenon of flooding that occurs in almost all regions the earth causes loss property and damage to public facilities many human lives. There are reports related with various solutions offered overcome flood problem.

Abstract Climate change could alter fluxes of organic matter and macronutrients through freshwater ecosystems potentially affecting stream organisms. However, riparian controls on litter dynamics offer an opportunity to adapt headwaters climate by protecting or restoring vegetation. We assessed how land cover climatic variability affected the supply, retention downstream transport particulate (...

Port regions are hubs connecting a nation and its hinterland to the rest of world. cities' authorities actors have always dealt with pressures compromises in sharing space between agriculture, tourism, industry, urban developments.
