Legume life history interacts with land use degradation of rhizobia: Implications for restoration success

Restoration of soil microbial communities, and microbial mutualists in particular, is increasingly recognized as critical for the successful restoration of grassland plant communities. Although the positive effects of restoring arbuscular mycorrhizal fungi during restoration of these systems have been well-documented, less is known about the potential importance of nitrogen-fixing rhizobium bacteria, which associate with legume plant species that comprise an essential part of grassland plant communities, to restoration outcomes. In a series of greenhouse and field experiments, we examined the effects of disturbance on rhizobium communities, how plant interactions with these mutualists changed with disturbance, and whether rhizobia can be used to enhance the establishment of desirable native legume species in degraded grasslands. We found that agricultural disturbance alters rhizobium communities in ways that affect the growth and survival of legume species. Native legume species derived..., , , # Data from: Legume life history interacts with land use degradation of rhizobia: implications for restoration success

土壤微生物群落（尤其是微生物共生体）的修复，如今愈发被视为草原植物群落成功恢复的关键环节。尽管在这类生态系统修复过程中，接种丛枝菌根真菌(arbuscular mycorrhizal fungi)的积极效应已有大量研究佐证，但人们对固氮根瘤菌(rhizobium bacteria)的潜在重要性仍了解有限——这类细菌与作为草原植物群落核心组成部分的豆科植物形成共生关系，其对修复效果的影响尚未得到充分探究。本研究通过一系列温室与田间实验，探究了干扰对根瘤菌群落的影响、植物与这些共生体的互作如何随干扰发生改变，以及能否通过施加根瘤菌促进退化草原中目标本土豆科物种的定植。研究发现，农业干扰会通过改变根瘤菌群落结构，进而影响豆科植物的生长与存活。本土豆科物种的...
