生活史现象的模式可以通过检查大范围的体重来证明。正相关关系存在于成体大小和变温动物[爬行动物，鱼类和两栖动物]的窝卵数，窝重，新生儿体重寿命[甲壳类动物和病毒]，成熟时间，至少对于恒温动物[鸟类和哺乳动物]，育雏或妊娠时间之间。这些因素的复杂性降低了较大动物的rmax，或者用更生理学的术语来说，rmax由个体生长速率决定。新生儿的生产与摄食和同化的比较表明，较大的哺乳动物在繁殖上投入的努力不成比例。如果将新生儿体重与成人体重和新生儿生长速率与新生儿体重进行异速生长，则会导致父母投资减少和发育时间延长。体尺关系代表了一般的生态学理论，在预测生态学的发展中具有相当大的前景。
Patterns in life history phenomena may be demonstrated by examining wide ranges of body wt. Positive relationships exist between adult body size and the clutch size of poikilotherms [reptiles, fish and amphibians], litter wt, neonate wt life span [in crustaceans and viruses], maturation time and, for homeotherms [birds and mammals] at least, brood or gestation time. The complex of these factors reduces rmax in larger animals or, in more physiological terms, rmax is set by individual growth rate. Comparison of neonatal production with ingestion and assimilation suggests that larger mammals put proportionately less effort into reproduction. Declining parental investment and longer development times would result if neonatal weight is scaled allometrically to adult weight and neonatal growth rate to neonatal weight. Body size relations represent general ecological theories and hold considerable promise in the development of predictive ecology.
