Abstract

A comparison of 26 allometric empiric equations relating animal body weight and progeny weight, size and weight of the clutch, as well as the accompanying processes in various classes of vertebrates has revealed a principle of large-scale transformation specific for poikilotherms and two others specific for homoiotherm birds and mammals. The appearance of huge terrestrial egg in reptiles and the transition from R-strategy to k-strategy was not accompanied by a rearrangement of the poikilotherm principle of reproduction pattern. Such rearrangement was required after the appearance of homoiotherm embryo and obligate parental care.

摘要

对26个将动物体重与后代体重、一窝的大小和重量以及各类脊椎动物的相关过程联系起来的异速生长经验方程进行比较后发现,变温动物有一个特定的大规模转变原则,恒温鸟类和哺乳动物有另外两个特定原则。爬行动物中巨大陆地产卵的出现以及从R策略到K策略的转变,并没有伴随着变温动物繁殖模式原则的重新排列。恒温胚胎和专职亲代抚育出现后,这种重新排列是必要的。
