Earthworms ( Lumbricus terrestris ) affect plant seedling recruitment and microhabitat heterogeneity
1. The effects of the anecic earthworm Lumbricus terrestris L. on plant seedling recruitment and spatial aggregation were investigated in a microcosm glasshouse experiment by varying plant seed size (small and large); functional groups (grasses, legumes, herbs); plant species diversity (1, 3, 6); and plant functional group diversity (1, 3). 2. Generally, earthworms buried seeds quickly irrespec...
متن کاملInfluence of Lumbricus terrestris Earthworms on the Structure of the Yeast Community
The taxonomic structure of yeast communities was studied in forest litter and soil, as well as in substrates transformed by the activity of Lumbricus terrestris earthworms (leaves in heaps, the gut contents, and coproliths). The activity of L. terrestris has a weak effect on the total yeast abundance but results in substantial changes in the community taxonomic composition. The share of ascomyc...
متن کاملthe study of populations and growth characteristics of earthworms (lumbricus terrestris l) in a soil salinized with nacl and the
abstract soil salinity in huge parts of the world, especially in arid and semi-arid regions, is a factor limiting growth of plant and other organisms. earthworm can be considered as an indicator of soil quality in agroecosystems, because of a positive correlation between earthworm abundance and the productivity of cropped plants. the main objective of this study was to realize the interaction b...
متن کاملCeramide glycanase from the earthworm, Lumbricus terrestris.
Ceramide glycanase (CGase) is an enzyme that cleaves the linkage between the sugar chain and the ceramide. To make this enzyme readily available, we have developed a simple method for preparing it from the earthworm, Lumbricus terrestris. The method involves Bio-Gel A-0.5m, octyl-Sepharose and p-aminophenylthiogalactoside-agarose column chromatography. By gel filtration, the molecular mass of e...
متن کاملFacilitation in the rapid response of the earthworm, Lumbricus terrestris L.
In previous papers (Roberts, 1962 a, b) the earthworm's rapid response, mediated through the giant-fibre reflex, was described and analysed. In the course of these experiments it was noticed that in the early stages of repetitive stimulation successive responses do not remain the same size but show a marked tendency to increase in magnitude. This staircase effect is particularly pronounced in f...
