Ephestia Kühniella

Acclimation in Anagasta kühniella pupae within the range of normal temperatures was not associated with changes in the rate of oxygen consumption or specific gravity of the haemolymph. Only when the pupae were conditioned at the extreme temperatures of 5 °C and 35 °C for about 16 and 8 hours, respectively, did their haemolymph become more concentrated. This was not due to desiccation. Thus the theory of osmoregulation does not explain the phenomenon of thermal acclimation satisfactorily.

Influence Of Temperature On

This investigative laboratory exercise uses the different relations between ambient temperature and metabolic rate in endotherms and ectotherms as a core concept to answer the following question: What thermoregulatory mode is employed by chicken embryos? Emphasis is placed on the physiological concepts that can be taught with this exercise, including methods for measuring rates of oxygen consumption, the relation between oxygen consumption and metabolic rate, the influence of temperature on metabolic rate, and the differences between endotherms and ectotherms both in the overall magnitude of metabolic rate and in the shape of the relation between metabolic rate and ambient temperature. Included in this article are respirometer designs suitable for teachers working with a wide variety of budgets and available equipment, specific laboratory protocols for collecting data, sample data, thought questions with sample answers, and suggestions for classroom implementation as a 1-, 2- or 3-wk laboratory exercise that can be taught at a variety of undergraduate levels.

Carbon Dioxide Production Rate

Adult scorpions (2.4g – 4.5 kg) were collected near Potchefstroom (26° .55’10” – 27° 10” 5”). Oxygen consumption rate (MO2) and carbon dioxide production rate (MCO2) were measured together with the metabolism of injected radioactive glucose.
