Respiratory Gas Tensions in the Environment,te the less than optimal gas composition of certain secluded habitats are often freed from risks of predation. Whereas some animals choose to live in confined, sometimes hypoxic areas (e.g. fossorial mammals), others are subject to periodic extremes of the medium in which they live (e.g. overwintering fish).

Kinetics of Oxygen and Carbon Dioxide Exchange,Surprisingly there has been little attention paid to non-mammalian vertebrates, despite considerable interest otherwise in their blood-gas equilibrium chemistry and cardiorespiratory structure-function relationships.

Modeling of Gas Exchange in Lungs, Gills and Skin,th steady state gas exchange, the models are those previously reviewed by Piiper (1982a) and Piiper and Scheid (1977, 1982, 1989). The Section 3, which addresses gas exchange in unsteady state, is inspired by the seminal studies on pulmonary gas exchange and CO. stores by Farhi and Rahn (1955a), and

Hemoglobin Physiology in Vertebrate Animals: a Cautionary Approach to Adaptationist Thinking,d environment has led us into a particular way of thinking about the role of hemoglobin in oxygen transport, in which the near omnipotence of natural selection is acknowledged in the design of the protein for function under particular circumstances (e.g., Powers 1980; Perutz 1983). The neo-Darwinian

This is, of course, a reflection of the metabolic utilization and production of these compounds by fish. The carbon dioxide/oxygen exchange ratio is usually between 0.7 and 1, whereas the ammonia/carbon dioxide exchange ratio is around 0.1 to 0.3. Variations
