Inland saline lakes are well known to be less biodiverse than fresh waters. In Australia, the most important driver affecting biodiversity is salinity that imposes an inverse linear relationship. However, in detailed studies across a wide salinity spectrum, the relationship is scale dependent. This is mediated in part by the range of salinity tolerated becoming broader as the maximum tolerated salinity increases. Other factors of importance sometimes include hydrology, habitat heterogeneity, season, pH and oxygen, but these are usually not easy to quantify. Even rarer is the influence of colonisation by marine organisms, which is applicable only at some sites near the coastline and the influence of ionic proportions on the presence of some species and, hence, diversity. The contribution of predation or competition on diversity, reported in some overseas salinas, is suspected but yet to be proved in Australia. The crustacean component in saline lakes is more influenced by these drivers than is most of the insect fraction.

限制澳大利亚盐湖生物多样性的驱动因素：综述

众所周知，内陆盐湖的生物多样性不如淡水。在澳大利亚，影响生物多样性的最重要的驱动因素是盐度，它会产生逆线性关系。然而，在广泛的盐度范围内的详细研究中，这种关系取决于尺度。这部分是由于随着最大可耐受盐度的增加，可耐受的盐度范围变得更宽。其他重要因素有时包括水文、栖息地异质性、季节、pH 值和氧气，但这些通常不容易量化。更罕见的是海洋生物定殖的影响，这仅适用于海岸线附近的一些地点，以及离子比例对某些物种的存在以及多样性的影响。捕食或竞争对多样性的贡献，在一些海外盐沼中报道，被怀疑但尚未在澳大利亚得到证实。与大多数昆虫部分相比，盐湖中的甲壳类动物成分受这些驱动因素的影响更大。
