Abstract
Soil microbial biomass is a key determinant of carbon dynamics in the soil. Several studies have shown that soil microbial biomass significantly increases with plant species diversity, but it remains unclear whether plant species diversity can also stabilize soil microbial biomass in a changing environment. This question is particularly relevant as many global environmental change (GEC) factors, such as drought and nutrient enrichment, have been shown to reduce soil microbial biomass. Experiments with orthogonal manipulations of plant diversity and GEC factors can provide insights whether plant diversity can attenuate such detrimental effects on soil microbial biomass. Here, we present the analysis of 12 different studies with 14 unique orthogonal plant diversity × GEC manipulations in grasslands, where plant diversity and at least one GEC factor (elevated CO2 , nutrient enrichment, drought, earthworm presence, or warming) were manipulated. Our results show that higher plant diversity significantly enhances soil microbial biomass with the strongest effects in long-term field experiments. In contrast, GEC factors had inconsistent effects with only drought having a significant negative effect. Importantly, we report consistent non-significant effects for all 14 interactions between plant diversity and GEC factors, which indicates a limited potential of plant diversity to attenuate the effects of GEC factors on soil microbial biomass. We highlight that plant diversity is a major determinant of soil microbial biomass in experimental grasslands that can influence soil carbon dynamics irrespective of GEC.

Several studies have shown that soil microbial biomass significantly increases with plant species diversity, but it remains unclear whether plant species diversity can also stabilize soil microbial biomass in a changing environment. This question is particularly relevant as many global environmental change (GEC) factors, such as drought and nutrient enrichment, have been shown to reduce soil microbial biomass. Experiments with orthogonal manipulations of plant diversity and GEC factors can provide insights whether plant diversity can attenuate such detrimental effects on soil microbial biomass. Here, we present the analysis of 12 different studies with 14 unique orthogonal plant diversity × GEC manipulations in grasslands, where plant diversity and at least one GEC factor (elevated CO2 , nutrient enrichment, drought, earthworm presence, or warming) were manipulated. Our results show that higher plant diversity significantly enhances soil microbial biomass with the strongest effects in long-term field experiments. In contrast, GEC factors had inconsistent effects with only drought having a significant negative effect. Importantly, we report consistent non-significant effects for all 14 interactions between plant diversity and GEC factors, which indicates a limited potential of plant diversity to attenuate the effects of GEC factors on soil microbial biomass. We highlight that plant diversity is a major determinant of soil microbial biomass in experimental grasslands that can influence soil carbon dynamics irrespective of GEC.</div></front></TEI><affiliations><list><country><li>Allemagne</li><li>Australie</li><li>France</li><li>Royaume-Uni</li><li>République populaire de Chine</li><li>Suisse</li><li>États-Unis</li></country><region><li>Basse-Saxe</li><li>Canton de Berne</li><li>Canton de Zurich</li><li>District de Leipzig</li><li>Saxe (Land)</li></region><settlement><li>Berne</li><li>Göttingen</li><li>Leipzig</li><li>Zurich</li></settlement><orgName><li>Université de Berne</li><li>Université de Zurich</li></orgName></list><tree><country name="Allemagne"><region name="Saxe (Land)"><name sortKey="Thakur, Madhav Prakash" sort="Thakur, Madhav Prakash" uniqKey="Thakur M" first="Madhav Prakash" last="Thakur">Madhav Prakash Thakur</name></region><name sortKey="Eisenhauer, Nico" sort="Eisenhauer, Nico" uniqKey="Eisenhauer N" first="Nico" last="Eisenhauer">Nico Eisenhauer</name><name sortKey="Ramirez, Nathaly Guerrero" sort="Ramirez, Nathaly Guerrero" uniqKey="Ramirez N" first="Nathaly Guerrero" last="Ramirez">Nathaly Guerrero Ramirez</name><name sortKey="Richter, Annabell Nicola" sort="Richter, Annabell Nicola" uniqKey="Richter A" first="Annabell Nicola" last="Richter">Annabell Nicola Richter</name><name sortKey="Roscher, Christiane" sort="Roscher, Christiane" uniqKey="Roscher C" first="Christiane" last="Roscher">Christiane Roscher</name><name sortKey="Scheu, Stefan" sort="Scheu, Stefan" uniqKey="Scheu S" first="Stefan" last="Scheu">Stefan Scheu</name><name sortKey="Steinauer, Katja" sort="Steinauer, Katja" uniqKey="Steinauer K" first="Katja" last="Steinauer">Katja Steinauer</name><name sortKey="Strecker, Tanja" sort="Strecker, Tanja" uniqKey="Strecker T" first="Tanja" last="Strecker">Tanja Strecker</name><name sortKey="Vogel, Anja" sort="Vogel, Anja" uniqKey="Vogel A" first="Anja" last="Vogel">Anja Vogel</name></country><country name="France"><noRegion><name sortKey="Milcu, Alexandru" sort="Milcu, Alexandru" uniqKey="Milcu A" first="Alexandru" last="Milcu">Alexandru Milcu</name></noRegion></country><country name="Suisse"><region name="Canton de Berne"><name sortKey="Manning, Pete" sort="Manning, Pete" uniqKey="Manning P" first="Pete" last="Manning">Pete Manning</name></region><name sortKey="Niklaus, Pascal A" sort="Niklaus, Pascal A" uniqKey="Niklaus P" first="Pascal A" last="Niklaus">Pascal A.
