✦ Synopsis

Abstract

Oxygen consumption was measured in the algal‐bearing and aposymbiotic hydra, Hydra viridis using a microrespirometer. In the light, green animals exhibited a lower rate of oxygen consumption than green animals in the dark or aposymbiotic animals. Treatment of the algal‐bearing animals with the photosynthetic inhibitor DCMU demonstrated that oxygen produced by symbiotic algae as a result of photosynthesis may supply part of the host's respiratory needs.

Direct measurements have shown that the heat output from the frog sartorius muscle stimulated under isometric conditions is maximum when the muscle is at reference length and is decreased at stretched and shortened lengths. Experiments were conducted to determine if oxygen consumption following isom

Adults of the lamprey Geotria australis are capable of surviving and taking up considerable volumes of oxygen when in humidified air. This accounts for their ability to leave water, move through moist vegetation and up and over dam walls, and thereby overcome barriers to their upstream migration. Im
