...Andreas Ziegler; Dirk Weihrauch; Monica Hagedorn; David W. Towle; Reiner Bleher SUMMARY The formation and resorption of CaCO 3 by epithelial cell layers require epithelial transport of protons. We used the anterior sternal epithelium of the terrestrial isopod Porcellio scaber as a model to study...

... crystals in permeabilised anterior and posterior sternal epithelium cells of Porcellio scaber during Ca 2+ -transporting and non-transporting stages of the moulting cycle using polarised-light microscopy. The results indicate ATP-dependent uptake of Ca 2+ into organelles. Half-maximal crystal growth...

...Jonathan C. Wright; Michael J. O’Donnell ABSTRACT Ammonia levels and pH were studied in body fluids of Porcellio scaber with special reference to ambient humidity and the timing of pleon fluid secretion and pleopodal ventilation. In high humidity (approximately 96.7%), concentrations of total...

...Jonathan C. Wright; Michael J. O’Donnell ABSTRACT Active water vapour absorption in Porcellio scaber is associated with the endogenous production of strongly hyperosmotic fluid in the pleoventral chamber (pleoventralraum; PV). Pre-desiccated animals show increased pleon fluid secretion within 1–2...
