Abstract

1.The energetic performance and food requirements of female Phillodryas chamissonis was determined during its breeding season at different ambient temperatures. 2. If the long tailed snake is active for 24 weeks, 25 to 32 30-g rodents are required for reproduction and maintenance. This is slightly more than one rodent per week. 3. The energy cost of reproduction (38 to 48% of total metabolism) is close to the values reported for fish (35% of metabolizable energy). 4. Due to their low metabolic rates, the theoretical predation pressure (on a prey biomass basis) exerted by the snakes should be 2 to 2.5% of that expected for endothermic predators of similar body size.

摘要
  1. 在不同环境温度下的繁殖季节，对雌性查米森氏菲洛德蛇的能量表现和食物需求进行了测定。2. 如果长尾蛇活跃24周，繁殖和维持需要25至32只30克重的啮齿动物。这略多于每周一只啮齿动物。3. 繁殖的能量成本（占总代谢的38%至48%）接近鱼类报告的值（占可代谢能量的35%）。4. 由于它们的代谢率较低，蛇施加的理论捕食压力（基于猎物生物量）应为类似体型的恒温捕食者预期压力的2%至2.5%。
