The temperature constraint hypothesis proposes that marine herbivorous fishes are rare at high latitudes relative to carnivorous fishes because low temperatures impair the digestion of plant material. To test this hypothesis, we compared the effects of temperature on the digestive performance and investment in digestion of marine fishes across trophic groups.

温度对营养族群中海水鱼类消化影响的全球荟萃分析

温度约束假设提出，相对于肉食性鱼类，高海拔地区的海洋草食性鱼类是罕见的，因为低温会损害植物材料的消化。为了验证这一假设，我们比较了温度对营养族群的海水鱼类的消化性能和消化投资的影响。
