摘要

Temperate anurans have energy substrates in the liver, fat bodies, carcass and gonads; these stores provide support formetabolism and egg production during hibernation, and for breeding activities in spring. This paper compares the energybudget shortly before hibernation among Rana chensinensis populations at elevations of 1400, 1700 and 2000 m alonga river in northern China. The larger frogs, regardless of elevation, had relatively heavy storage organs and the massesof nearly all these organs were positively correlated with each other. After controlling for the effect of body size, wefound no significant difference in energetic organ mass among different age classes for each ofthe three populations. Therewere sexual differences in energy strategy. Males in all populations accumulated greater reserves in liver, fat bodies andcarcass than did females. I n contrast, females put more energy into their ovaries and oviducts. Frogs from higher elevationstended to have heavier organs than those from lower elevations; however, the pattern did not vary systematically alongfine environmental gradients. Mid-elevation R. chensinensis built up significantly more reserves than low-elevationindividuals, but were similar to their highland conspecifics. Males from higher elevations tended to have heavier liverand fat bodies; females were similar in liver and ovary mass across all elevations, but formed heavier fat bodies, oviductsand somatic tissue at higher elevation sites.
