植物-土壤生物相互作用和土地利用强度影响植物个体的适应性和竞争力,从而影响群落中植物物种的丰度。因此,可以预期土壤生物群和土地利用强度对草原植物物种本地丰富度的影响之间存在联系。在两个温室实验中,我们研究了土壤生物群的影响,从草地上的土地利用强度不同的三个草种,不同的本地丰度沿着这个土地利用梯度。我们感兴趣的是那些与土地利用强度相关的土壤生物区系效应,以及这些效应是直接还是间接起作用。因此,我们在两个单独的实验中将这三种植物作为单一个体和混合物种植,并比较它们的性能。作为单一植物,所有三种草在有和没有土壤生物群的情况下表现出相似的性能。与此相反,在混合物中的物种的生长在土壤生物群的存在或不存在的反应不同。这导致了不同的土壤生物区系的影响,往往对应于模式的物种特定的丰度在该领域的两个测试的三个物种。我们的研究结果强调了植物和土壤微生物之间的间接相互作用的重要性,并表明,土壤生物群和植物-植物相互作用的综合影响参与构建植物群落。总之,我们的实验表明,土壤生物区系可能有可能改变植物-植物相互作用的影响,从而影响草原植物物种的丰度和多样性。
Biotic plant-soil interactions and land-use intensity are known to affect plant individual fitness as well as competitiveness and therefore plant-species abundances in communities. Therefore, a link between soil biota and land-use intensity on local abundance of plant species in grasslands can be expected. In two greenhouse experiments, we investigated the effects of soil biota from grassland sites differing in land-use intensity on three grass species that vary in local abundances along this land-use gradient. We were interested in those soil-biota effects that are associated with land-use intensity, and whether these effects act directly or indirectly. Therefore, we grew the three plant species in two separate experiments as single individuals and in mixtures and compared their performance. As single plants, all three grasses showed a similar performance with and without soil biota. In contrast, in mixtures growth of the species in response to the presence or absence of soil biota differed. This resulted in different soil-biota effects that tend to correspond with patterns of species-specific abundances in the field for two of the three species tested. Our results highlight the importance of indirect interactions between plants and soil microorganisms and suggest that combined effects of soil biota and plant–plant interactions are involved in structuring plant communities. In conclusion, our experiments suggest that soil biota may have the potential to alter effects of plant–plant interactions and therefore influence plant-species abundances and diversity in grasslands.
