Abstract
The effects of acute temperature change on the cost of bluegill Lepomis macrochirus swimming were quantified. At 14 degrees C, maximum labriform swimming speed (U(lab,max)) was reduced relative to that at the acclimation temperature of 22 degrees C, but total cost of transport (T(TC)) remained unchanged. At 30 degrees C, U(lab,max) was the same as at 22 degrees C, but T(TC) was 66% greater.
摘要
本研究旨在量化蓝鳃太阳鱼在急性温度变化下游泳的成本。结果表明，14°C 时，蓝鳃太阳鱼的最大拟态游速（U(lab,max)）较 22°C 时的适应温度显著降低，但总运动成本（T(TC)）保持不变。而在 30°C 时，U(lab,max)与 22°C 时相同，但 T(TC)增加了 66%。
