#GlobalSoilMacroFauna | Official template to report Data of Soil Macro Fauna abundance from TSBF Method

Mathieu, Jérôme; Lavelle, Patrick; Brown, George

This is the updated official template to report soil macrofauna data produced with the TSBF sampling protocol for the project GlobalSOilMacrofauna. (TSBF_template _2021_03_03.xlsx)

 

Our goals are:

  1. To make a large-scale synthesis of the effects of human activity on soil macrofauna and to explore the links to ecosystem services delivery, especially primary productivity.
  2. To produce maps of abundance and diversity of soil macrofauna on a global scale.
  3. To produce information that will reach decision-makers and practitioners, especially farmers and land managers.

We are looking for data on the abundance and biomass of 17 soil (+litter) fauna groups. The list of the taxa is given in the template.

Ideally

  • The specimens should have been sampled in a TSBFish method, ie a monolith (25x25cmx30cm) extracted from the soil. Soil cores are also possible. Pitfall trap data are ok but can be used only for the mapping work package, and need to be large enough.
  • The groups should have been sampled together, but we can also integrate data focused on a single group or on a subset of the groups.
  • Data should come with data regarding habitat such as soil properties, land management, agricultural practices, primary productivity. But nothing is mandatory except:
    • Land-use type
    • Sampling date (YYYY-MM-DD)
    • Geographic coordinates in decimal degrees

Taxonomical Resolution

The taxonomic resolution required for the database is low (typically at class or family level.

But please note that for a more specific part of the project, we are also looking for data at a finer resolution data, especially morphospecies or even species data, in order to compare the trends between low and high taxonomical resolution.

Sampling Resolution

We prefer data a the soil monolith level, (1 line = 1 soil monolith), or finer, when soil layers are available, but we can also work with data aggregated at the higher level (transect or plot), but in this case, we need the number of samples per transect.

Spatial and temporal Resolution

We target a very high spatial resolution (100x100m), which implies that we need spatial coordinates of the samples with high accuracy, ideally around 15m.  If the spatial accuracy of your data is is coarser, please advise us. Same for the sampling date: we ideally need the year, month and day of the collection of each sample.

Co-authorship policy

We intend to be inclusive in terms of co-authorship. It is difficult to give the amount of data required to become a potential co-author, but we can roughly say that the threshold can be about data from three different localities, spaced by more than 100km. But this is just an indication. Please note that co-authors are expected to contribute actively to paper writing. The credits of all data will be reported.

 

Data Management Plan

We plan to publish the data on open access (with appropriate credits), but this is not mandatory for all datasets (we can remove specific datasets from the open database).

 

Thank you in advance for your help. This is definitely a collaborative exercise. All contributions welcomed!
