| 1 | Microhabitat heterogeneity associated with Vanilla spp.and its influences on the microbial community of leaf litter and soil显示文摘The impact of forest microhabitats on physiochemical properties of the soil and that of microbial communities on tropical soils remain poorly understood.To elucidate the effect of tropical forest stand on leaf litter and soil microbial communities,we studied enzyme activities,microbial biomass,and diversity in three distinct microhabitats in terms of plant richness,diameter at breast height(DBH),and physiochemical properties of soil and litter,each associated with a different Vanilla sp.In the soil,positive correlations were found between electrical conductivity(EC)and total organic carbon(TOC)with phosphatase activity,and between nitrogen(N)and water-soluble carbon(WSC)content with urease activity(UA).In the litter,the water content was positively correlated with bacterial and fungal biomass,and N and WSC contents were positively correlated with fungal biomass.Positive correlations were found between plant richness and UA in the soil,plant richness and fungal biomass in the soil and litter,and DBH and fungal biomass in the litter.Amplicon sequencing revealed differences between microhabitats in the relative abundance of some fungal and bacterial taxa and in the bacterial community composition of both litter and soil.Bacterial richness and diversity were different between microhabitats,and,in litter samples,they were negatively correlated with DBH and plant richness,respectively.By contrast,none of the soil and litter physiochemical properties were significantly correlated with microbial diversity.Our results show that significant shifts in enzyme activity,microbial biomass,and diversity in the microhabitats were driven by key abiotic and biotic factors depending on the soil or litter sample type. | Gabriela Montes de Oca-Vasquez Frank Solano-Campos Bernal Azofeifa-Bolanos Amelia Paniagua-Vasquez Jose Vega-Baudrit Antonio Ruiz-Navarro Ruben Lopez-Mondejar Felipe Bastida | 2020 | Soil Ecology Letters2020，2，3： | 2 |

| 3 | Abiotic and biotic drivers of struvite solubilization in contrasting soils显示文摘Phosphorus(P) limitation in the coming decades calls for the utilization of alternative fertilizers in agriculture. Struvite is a promising P source, but its potential role as a fertilizer is dependent on different physical, chemical, and biological properties, which are very heterogeneous in soil, complicating the prediction of the best soil conditions for its application. Here, we evaluated the solubility of struvite in soil, its redistribution into P fractions, and its potential abiotic and biotic drivers in 62 globally distributed soils with contrasting properties through an incubation assay. We found that after 40 d, about 35% of struvite P was redistributed into soil fractions more accessible to plants and microbes. Phosphorus redistribution from struvite was driven by a complex suite of soil physical, chemical, and microbial properties as well as environmental factors that varied across soils. Soil texture played a critical role in determining the redistribution of P in struvite-amended soils in soluble(H2O extraction), labile(NaHCO3 extraction), and moderately labile(NaOH extraction) fractions.In addition, the soil solution cation concentration was one of the most important drivers of available struvite-derived P fractions. The great importance of texture and cations in determining struvite-derived P fractions in soil was contrasted with the relatively minor role of pH. At the microbial level, the number of bacterial operational taxonomic units(OTUs) from the unfertilized soils that correlated with struvite-derived P fractions was higher than that of fungi. The number of OTUs that correlated with the struvite-derived soluble P fraction was dominated by fungi, whereas the number of OTUs that correlated with the struvite-derived labile P fraction was dominated by bacteria. Overall, this study provided a predictive framework for the potential use of struvite as a P fertilizer in contrasting soils. | Antonio RUIZ-NAVARRO Manuel DELGADO-BAQUERIZO Concha CANO-DíAZ Carlos GARCíA Felipe BASTIDA | 2023 | Pedosphere2023，33，6： | 0 |
