Abstract:

Aquatic coastal systems are affected by high fluctuations in salinity and the zooplankton may rely on dispersal or dormancy to recolonise these environments. Here, we analysed the long-term dynamics of the zooplankton community over 6 years during large salinity fluctuations in a coastal lagoon (Garças Lagoon, Brazil) and the effect of salinity on the hatching patterns of the resting egg bank. We hypothesised that salinity is the main driving factor of the zooplankton community structure, and that increases in salinity reduce the species richness and the abundance of hatchlings.

Abstract:

A new algal-bacterial granular sludge treatment method was used to treat salty eutrophication water. The results indicated that the treatment removed more than 98% of the total inorganic nitrogen and the total phosphorus after a 15 d cultivation period using 2% salinity simulated eutrophication water. For the 4% salinity simulated water, the total phosphorus was not able to be removed and was even higher in the effluent; and the total inorganic nitrogen was only removed 17%. Thus, the algal-bacterial granules were efficient for removing nitrogen and phosphorus in 2% salinity eutrophication wat

Water body type, salinity, depth and TP together explained 25.3% of the variation in the diatom data and were all independently significant predictors. A diatomsalinity model (r2jack = 0.887, root mean square error of prediction = 0.246 log salinity, g·L1) was developed

Salinity is becoming more expanded globally. Soil salinity imposes a great challenge for vegetable-crops production in arid and semiarid regions. Cucumber (Cucumis sativus L.) is the fourth most important vegetable crop worldwide. In this review, we discuss the complex network of effects, and the ways cucumber responds to salinity. Salt stress inhibits almost all growth phases and yield components of cucumber. Accumulation of Na+ and/or Cl- ions in cucumber tissues disturbs the absorption of other ions causing ionic imbalance which affect stomatal opening. Nevertheless, high levels of NaCl in
