Erratum to: Earthworm burrowing activity of two non-Lumbricidae earthworm species incubated in soils with contrasting organic carbon content (Vertisol vs. Ultisol)

Comparative toxicity of ten organic chemicals to four earthworm species.

Ten organic chemicals were tested for toxicity to four earthworm species: Allolobophora tuberculata, Eisenia fetida, Eudrilus eugeniae and Perionyx excavatus, using the European Economic Community's (EEC) earthworm artificial soil and contact testing procedure. The phenols were the most toxic chemicals tested, followed by the amine, substituted benzenes, halogenated aliphatic hydrocarbon, polyc...

Ontogenetic scaling of burrowing forces in the earthworm Lumbricus terrestris.

In hydrostatic skeletons, it is the internal fluid under pressure surrounded by a body wall in tension (rather than a rigid lever) that enables the stiffening of the organism, the antagonism of muscles and the transmission of force from the muscles to the environment. This study examined the ontogenetic effects of body size on force production by an organism supported with a hydrostatic skeleto...

Riboflavin content in autofluorescent earthworm coelomocytes is species-specific.

We have recently shown that a large proproportion of earthworm coelomocytes exhibit strong autofluorescence in some species (Dendrobaena veneta, Allolobophora chlorotica, Dendrodrilus rubidus, Eisenia fetida, and Octolasion spp.), while autofluorescent coelomocytes are very scarce in representatives of Lumbricus spp. and Aporrectodea spp. Riboflavin (vitamin B2) was identified as a major fluoro...

Earthworm (Eisenia andrei) Avoidance of Soils Treated with Cypermethrin

The pyrethroid insecticide cypermethrin is used for agricultural and public health campaigns. Its residues may contaminate soils and the beneficial soil organisms, like the earthworms, that may ingest the contaminated soil particles. Due to its ecological relevance, earthworms Eisenia andrei/fetida have been used in different ecotoxicological tests. The avoidance of soils treated with cypermeth...
