Earthworms and Collembola Relationships: Effects
1 2 Relationships between anecic earthworms (Lumbricus terrestris and Aporrectodea 3 giardi) and the collembolan species Heteromurus nitidus (Templeton, 1835), which is known 4 to be attracted to earthworms, were investigated in an 8-week laboratory experiment. Our 5 aims were (1) to assess whether earthworms influence the population dynamics of H. nitidus, 6 and (2) to study pathways of influe...
متن کاملEarthworm excreta attract soil springtails: laboratory experiments on Heteromurus nitidus (Collembola : Entomobryidae)
Microarthropods are often found more abundantly in soils with earthworms than in soils without. Earthworms probably create a favourable environment for microarthropods but few studies have aimed to explain this earthworm effect. The soil collembolan (Hexapoda) Heteromurus nitidus, living in soils at pH > 5 only and thus rich in earthworms, is particularly attracted by earthworms in humus cores....
متن کاملHeterogeneity in soil animal communities and the development of humus forms
Two examples are given of strong relationships between the activity of soil animals and the development of humus forms in a mountain spruce forest and a lowland Scots pine stand. Both were based on field distributions of fauna and humus components. The vertical heterogeneity of soil animal communities in a moder humus profile under Scots pine is related to successional processes occurring durin...
متن کاملSpecies traits and habitats in springtail communities: a regional scale study
1 Although much work has been done on factors patterning species trait assemblages in 2 emblematic groups such as plants and vertebrates, more remains to be done in 3 belowground invertebrate species. In particular,relationships between species traits and 4 habitat preferences are still a matter of debate. Springtails were sampled in a 5 heterogeneous landscape centered on the Sénart forest, ne...
