Abstract Salinization of the upper aquifer northern Elbe-Weser region almost extends to surface. Chloride content exceeds 250 mg/l and groundwater is therefore, according German Drinking Water Ordinance, not suitable as drinking water. The chloride in originates from early flooding with seawater which occurred during Holocene sea level rise. Depth extent salinization were mapped by airborne ele...

BACKGROUND Although the effect of water level on germination in soil seed banks has been documented in many ecosystems, the mechanism is not fully understood, and to date no empirical studies on this subject exist. Further, no work has been done on the effect of water level on seed banks of drying and saline-alkaline wetlands in alpine areas on the Tibetan Plateau. METHODOLOGY We examined the...

Montes (eds.), Forests in Development: A Vital Balance, DOI 10.1007/978-94-007-2576-8_5, © Springer Science+Business Media B.V. 2012 Abstract South American tree plantations expand at a rate of 5,000 km 2 /year favored by increasingly globalized markets and local economic conditions. The main hydrological impacts of these plantations involve shifts in (a) the partition of p...

desertification relates to the both the process and end state of drylands degradation. salinization and alkalinization are two indicators of soil degradation in arid and semi-arid regions. the main objectives of this research is monitoring of soil salinity using high spectral and spatial resolution of remote sensing to assess desertification in the marvast plain, yazd province. two images of te...

Freshwater salinization is a widespread issue, but evidence of ecological effects on aquatic communities remains scarce. We experimentally exposed salt-naive plankton north-temperate, freshwater lake to gradient chloride (Cl−) concentration (0.27–1400 mg Cl L−1) with in situ mesocosms. Following 6 weeks, we measured changes the diversity, composition, and abundance eukaryotic 18S rRNA gene. Tot...
