Responses of earthworm communities to crop residue management after inoculation of the earthworm Lumbricus terrestris (Linnaeus, 1758)

Ceramide 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...

Biomass and Behavioral Responses of Earthworm,Lumbricus Terrestris to Copper Chloride

Introduction: Among soil species earthworms are ubiquitous, abundant and important for soil processes, constituting the largest terrestrial faunal biomass and are also impacted by soil pollutants. The primary purpose of this study was to determine whether changes in earthworm biomass and behavior could serve as a good indicator for copper toxicity in soil systems. Another aim of the study was t...

The nitrogenous metabolism of the earthworm (Lumbricus terrestris).

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...

Scaling of the hydrostatic skeleton in the earthworm Lumbricus terrestris.

The structural and functional consequences of changes in size or scale have been well studied in animals with rigid skeletons, but relatively little is known about scale effects in animals with hydrostatic skeletons. We used glycol methacrylate histology and microscopy to examine the scaling of mechanically important morphological features of the earthworm Lumbricus terrestris over an ontogenet...
