(From Thomas (150).) specimens measured during the summer (tested at 12CC and 20°C). More- over, when kept at a constant temperature, these fish still show a seasonal rhythm with higher winter respiration. In the sand crab Emerita talpoida oxygen consumption in winter is greater than in summer at temperatures below 20 C; augmentation of winter metabolism is about fourfold at 3 C. Similarly, excised tissues of the bivalve Mercenaria mercenaria tend to show higher winter rates of oxygen consumption. These animals become adjusted to seasonal changes in temperature with the result that the metabolic rate.
