... 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...

Total Ammonia Concentration and P H of Haemolymph, Pleon Fluid and Maxillary Urine in Porcellio Scaber Lattreille (Isopoda, Oniscidea): Relationships to Ambient Humidity and Water Vapour Uptake

Jonathan C. Wright, Michael J. O’Donnell

J Exp Biol (1993) 176 (1): 233–246.

DOI: https://doi.org/10.1242/jeb.176.1.233

Published: 1 March 1993

...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...
