据了解，在整个地质历史中，在高度受限的海洋盆地中形成了大量的盐堆积或盐巨人，但它们对生物多样性的影响只得到零星的研究。在597至533万年前的墨西尼亚盐危机(MSC)期间，地中海上的盐巨人是由于其通往大西洋的门户受到限制而形成的。
在这里，研究人员根据地中海化石记录的汇编，量化了与MSC相关的生物多样性变化。结果表明，2006年前MSC海洋物种的86个特有物种在危机中幸存下来，且地中海目前向东递减的丰富度梯度是MSC后形成的。

Abstract: 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.
