Land salinization is widespread in countries of the arid zone, including Aral Sea basin, where 4 million hectares irrigated land are salt-affected, causing high economic losses. Current saline soil reclamation practices include leaching and deep drainage to remove excess water outside zone. Growing pressure on limited resources makes this practice ineffective. An alternative biological methods ...

The 9th International Conference on Salt Lake Research was held 26-30 September 2005 in Western Australia at the Curtin University of Technology, Perth, Australia. One hundred scientists from 10 countries presented research on a diverse array of topics highlighting research findings and opportunities, and management challenges associated with inland saline waters. Major emergent themes of the c...

Virtual geographic environments (VGE) are environments pertaining to the relationship between post-humans and 3-D virtual worlds. Post-humans are defined as a combination of humans in the real world with 3-D avatars in 3-D virtual worlds. VGE can be a platform for the public participation in spatial data analyses, in model computation and simulation, and in environmental planning and decision m...

The aquatic bacterial group SAR11 is one of the most abundant organisms on Earth, with an estimated global population size of 2.4 x 10(28) cells in the oceans. Members of SAR11 have also been detected in brackish and fresh waters, but the evolutionary relationships between the species present in the different environments have been ambiguous. In particular, it was not clear how frequently this ...

Abstract Soil salinity represents one of the major threats land degradation and desertification under arid semi-arid environments. It has an adverse influence on soil-water-plant relationships, posing serious challenges to agricultural productivity. The main objective this work was monitor effect farmyard manure (FYM) application irrigation with low-quality water dynamics dissolved salts yield ...

Colonizations from marine to freshwater environments constitute among the most dramatic evolutionary transitions in the history of life. Colonizing dilute environments poses great challenges for acquiring essential ions against steep concentration gradients. This study explored the evolution of body fluid regulation following freshwater invasions by the copepod Eurytemora affinis. The goals of ...
