THE USE OF TAYLOR POWER-LAW TO DESCRIBE THE AGGREGATED DISTRIBUTION OF EARTHWORMS IN PERMANENT PASTURE AND ARABLE SOIL IN SCOTLAND

The aggregated horizontal distribution of earthworms was investigated in 200 fields on 100 farms throughout Scotland using Taylor's power la w. Results indicated that the index of aggregation b was relatively co nsistent for juvenile and adult earthworms from both pasture and arabl e fields. It is suggested that before statistical analysis the most ap propriate transformation for these populations would be a cube-root tr ansformation.
