In general, the density of the soil mesofauna (Enchytraidae, Collembola
and Acarina) on peat land increased together with escalating the land age after drained land for forestry in Ireland.
In contrast, ablation reduced the number of Collembola
captured to just 29% of that of the other two treatments (interaction of taxon and treatment after square root transformation: F = 2.
In Primary insect types in the Illinois Natural History Survey Collection, exclusive of the Collembola
Microarthropods were extracted over 96 h by using a Tullgren funnel and classified into Collembola
, Oribatida, or Mesostigmata (Aoki 1999).

This can indirectly impact the local populations of many animal groups, from decomposers such as Collembola
, to species much higher up the food chain.

are arthropods that are found in abundance in the surface layers of soils in a variety of habitats, where they act as scavengers, feeding on decaying vegetation and soil fungi (Hopkin 1997).
However, studies on lycosid spiders in the field report that Collembola
, Diptera, Cicadina, Aphidina, and Araneae would be the main prey groups for this family (Nentwig 1987).
