A Comparative Study of the Respiratory Metabolism in Porcellio laevis(Lat.) and Armadillidium vulgare(Lat.): Response to Temperature, Photoperiod and Oxygen Concentration
Abstract
Relationship of body weight, imposed fasting, temperature, light intensity, and oxygen concentration to oxygen consumption in Porcellio laevis and Armadillidium vulgare has been investigated in a series of laboratory experiments. It was observed that (1) the metabolic response in the two species to temperature change was a uniform increase of oxygen consumption with increasing temperature from 15 degrees C to 60 degrees C. Beyond 30 degrees C, the oxygen consumption in each species fell, and the thermal death point was reached at about 40 degrees C. (2) The response to decreasing oxygen concentrations was a corresponding decrease in oxygen consumption. Armadillidium vulgare was a partial regulator while Porcellio laevis was able to conform its internal state to the changing oxygen levels. (3) In each species there was a decrease in metabolic rate with increasing body weight. (4) On the basis of their general activity level and oxygen consumption rate, Porcellio appeared to be a nocturnal species, while Armadillidium had a day active metabolism.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
