The response of soil organisms (nematodes, rotifers and tardigrades) to the treatments is monitored by sampling soil on an annual basis. Name: John "Jeb" E.

The only organisms that were found in these samples, were nematodes (Scottnema).

In this case, a column name  called "SML" would be  "The total number of living male Scottnema lindsayae adult nematodes..."   Preserved samples are stored in the NREL Preserved Nematode Collection in room 226, College of Natural Resources, Colorado State University. Original data are stored in Room A208, Natural and Environmental Sciences Building, Colorado State University. https://mcm.lternet.edu/sites/default/files/data/SOILS_LTM_ALGAE.csv SOILS_LTM_ALGAE eng; US McMurdo Dry Valleys LTER SOILS_LTM_ALGAE Data Source Definition : Comma Delimited spreadsheet containing the LTM ALGAE data described here.
