In salt-affected environments, salinity shapes ecosystem functions and species composition. Apart from salinity, however, we know little about how soil chemical factors affect plant species. We hypothesized that specific ions, most of which contribute to salinity, co-determine plant niche differentiation. We asked if the importance of ions differs for species with (halophytes) and without (associated species) physiological adaptations to saline soils.

除了盐度：植物对土壤离子成分表现出不同的反应

在受盐影响的环境中，盐度影响生态系统功能和物种组成。然而，除了盐度之外，我们对土壤化学因素如何影响植物物种知之甚少。我们假设特定离子（其中大部分有助于盐度）共同决定植物生态位分化。我们询问对于对盐土有生理适应的物种（盐生植物）和没有生理适应的物种（相关物种），离子的重要性是否有所不同。
