A global database of soil microbial phospholipid fatty acids and enzyme activities

Abstract

Soil microbes drive ecosystem function and play a critical role in how ecosystems respond to global change. Research surrounding soil microbial communities has rapidly increased in recent decades, and substantial data relating to phospholipid fatty acids (PLFAs) and potential enzyme activity have been collected and analysed. However, studies have mostly been restricted to local and regional scales, and their accuracy and usefulness are limited by the extent of accessible data. Here we aim to improve data availability by collating a global database of soil PLFA and potential enzyme activity measurements from 12,258 georeferenced samples located across all continents, 5.1% of which have not previously been published. The database contains data relating to 113 PLFAs and 26 enzyme activities, and includes metadata such as sampling date, sample depth, and soil pH, total carbon, and total nitrogen. This database will help researchers in conducting both global- and local-scale studies to better understand soil microbial biomass and function.

The PLFA and enzyme activity database contains 12,258 samples from 3,743 locations. The purple colour gradient shows the degree to which climatic space is represented by the samples (scale of 0 to 1, see Technical Validation section). Grey regions do not have sufficient climate data available to evaluate climatic representation. The histogram and donut plots show number of samples (in parentheses) from the PLFA (blue) and enzyme (red) datasets collected in different years, from different continents, from different biomes, and within different categories of maximum sample depth. Only large segments of donut plots are labelled. Temp. = temperate.

Variation in PLFA content across biomes. Boxes show median and interquartile range, with whiskers 1.5 times the interquartile range. Biomes are ordered according to the median value across all 14 PLFAs. Numbers show the sample size in each category.

Variation in soil enzyme activity across biomes. Boxes show median and interquartile range, with whiskers 1.5 times the interquartile range. Biomes are ordered according to the median value across all five enzyme activities. Numbers show the sample size in each category.

Examples of countries that have data available for multiple years. Points are coloured according to the sampling year; points are grey where sampling year is unavailable. Text indicates the number of locations in each country, and the number of unique time points (year–month combinations) that samples were collected at.
