Massive salt accumulations, or salt giants, have formed in highly restricted marine basins throughout geological history, but their impact on biodiversity has been only patchily studied. The salt giant in the Mediterranean Sea formed as a result of the restriction of its gateway to the Atlantic during the Messinian Salinity Crisis (MSC) 5.97 to 5.33 million years ago. Here, we quantify the biodiversity changes associated with the MSC based on a compilation of the Mediterranean fossil record. We conclude that 86 endemic species of the 2006 pre-MSC marine species survived the crisis, and that the present eastward-decreasing richness gradient in the Mediterranean was established after the MSC.

Currently, high-salt diets have become one of the world's biggest dietary crisis and long-term high-salt diets are seriously detrimental to human health. In response to this situation, the present study proposed a saltiness enhancement strategy using alginate, which is a dietary fibre from brown algae and has many health benefits, such as regulating intestinal microbiota, anti-hypertension and anti-obesity. The comparison of alginates with different viscosities showed that alginate of 1000-1500 cps at a concentration of 1.

Due to their fast precipitation rate, sulfate evaporites represent excellent repositories of past life on Earth and potentially on other solid planets. Nevertheless, the preservation potential of biogenic remains can be compromised by extremely fast early diagenetic processes.

Climate change jeopardizes the food security gains achieved in India since the Green Revolution, especially by impacting the productivity of the rice-wheat system in the Indo-Gangetic Plain, a region that serves as the 'breadbasket' of South Asia. In this study, we characterized the potential of long-term conservation agriculture (CA) based management practices (i.e.

Article Synopsis
  • Extreme weather and poor water conditions are worsening freshwater shortages, leading to studies on using saltwater for irrigation in tomatoes.
  • A 2-year pot experiment evaluated different irrigation (85%, 70%, 55% field capacity) and salinity levels (2g/L, 4g/L, 6g/L) to measure yield, quality, and water-saving indicators.
  • Results indicated that a combination of 66-72% FC and 2 g/L salinity provided the best outcomes, promoting high yield and quality while using salty water for irrigation.
