Saline to freshwater invasions have become increasingly common in recent years. A key hypothesis is that rates of freshwater invasions have been amplified in recent years by increased food concentration, yet this hypothesis has remained unexplored. We examined whether elevated food concentration could enhance freshwater tolerance, and whether this effect evolves following saline to freshwater i...

in most semiarid and arid areas, fresh water shortage compels managers to use low quality water sources with high salinity to irrigate turf and landscape. recent research has noticed that management of nitrogen fertilization can alleviate salinity effects on plants. this greenhouse sand culture experiment was conducted in order to investigate morphological and physiological responses to salinit...

The Ord River Irrigation Area (ORIA) is located within northern Western Australia near the Northern Territory border. Since the beginning of irrigated agriculture in the ORIA the groundwater levels have been continuously rising and are now close to the soil surface in some parts of ORIA in northern Western Australia. The groundwater is now saline throughout most of the ORIA and soil salinity ri...

coastal monitoring programs are valuable tools for assessing the current state of coastal environments, for determining spatial and temporal trends in pollution and identifying potential sources of contaminants. monitoring often involves organisms from different environments, such as estuarine and intertidal zones, where conditions (e.g. salinity, temperature) fluctuate. Biomarkers “report” on ...

objective: soil salinity is one of the major worldwide environmental constraints affecting agricultural production in arid and semiarid regions. lack of proper management of water and soil resources lead to increase soil salinity and reduce soil fertility. on the other hand, it seems simple and cheap method of measuring soil salinity is necessary. the aim of this study was to determine the rela...

DOR: 98.1000/2383-1251.1398.6.1.11.1. 1575.41 Extended Abstract Introduction: Strangle wort (Cynanchum acutum) is a perennial weed that could be propagated by seeds and vegetative organs. This brings about harvesting problems for some crops such as cotton, sugar beet, wheat and maize. In recent years, this weed has caused huge losses in sugar cane fields. The role of environmental condition...

Osmoregulation capabilities of two size groups (1 and 2g) of zander , Sander lucioperca, fingerlings were investigated survival rate, plasma osmolarity, sodium (Na+), chloride (Cl-) ion concentrations and cortisol level within 0, 6, 24, 72 and 240 h after abrupt transfer from freshwater to 7 and 12‰ salinity. Also, some hematological parameters were measured at 240h. The plasma osmolarity and ...
