Abstract

V originále

Measuring standard metabolic rates in newts remains a complicated task despite substantial methodological and technological advances in the field. We examined the influence of aquatic versus terrestrial conditions in respirometry chambers on measurements of respiratory gases and motor activity in Alpine Newts, Ichthyosaura alpestris, during their aquatic phase. Aquatic conditions during intermittent respirometry trials biased values of carbon dioxide production more than values of oxygen consumption, which caused marked differences in estimates of respiratory quotient. Placing newts in water increased their motor activity relative to terrestrial conditions during respirometry trials, which made obtaining representative estimates of standard metabolic rates complicated. We conclude that the absence of water, rather than aquatic conditions in respirometry chambers, produces more-accurate metabolic measurements in newts during their aquatic phase.
