Bioavailability and cellular effects of metals on Lumbricus terrestris inhabiti...
Amaral, André; Soto, Manu; Cunha, Regina Tristão da; Marigómez, Ionan; Rodrigues, ArmindoCopyright © 2005 Elsevier Ltd. All rights reserved. ; Whether the radial thickness (RT) of the chloragogenous tissue and intestinal epithelium of earthworms (Lumbricus terrestris) reflects the bioavailability of metals in soils was investigated in two areas, one with active volcanism (Furnas) and another with no volcanic activity since 3 million years ago (Santa Maria), in the Azores. Metal contents in soil sa...

Morphology and histology of the digestive gland of Oxychilus (Drouetia) atlanti...
Lopes, Marco; Rodrigues, Armindo; Marigómez, IonanLittle information exists on the histology of Zonitidae digestive system. This study deals with a detailed characterization of the different types of cells comprising epithelium lining the digestive gland of 0xychilus atlanticus. From light and scanning electron microscope (SEM) studies, three types of differentiated cells can be identified in the digestive gland: digestive cells, excretory cells and calcium ce...
