From the abstract for the referenced paper:
The numbers of free living nematodes in more than 40 Macquarie Island soils were recorded at three different times during the year. The principal conditions affecting the populations have been discussed and it is concluded that the numbers and types of algae and bacteria are of major importance since most of the nematode species identified are believed ... to feed on these groups of microorganisms. An attempt has been made to assess the relative importance of nematodes in processes of decomposition in Macquarie Island soils.
In August, September and February of 1951-52, soil samples were collected from 42 different localities considered to be reasonably representative of the range of environments occurring on Macquarie Island. Where possible the samples included the surface 6 inches of soil taken from a number of points in each locality.
The fields in this dataset are:
Soil Temperature (degrees farenheit)
Number of Nematodes
