The effects of nuptial colour, parasites and body size on reproductive success were examined in a natural population of three-spined stickleback Gasterosteus aculeatus. Reproductive males were collected, with the contents of their nests, during the embryo-guarding stage from Lynne Lake (Cook Inlet, Alaska, U.S.A.), and nuptial colour, infection status and body size were recorded. Regression analysis revealed that male body size was the only predictor, of those measured, of reproductive success in nature.
在自然环境下的三刺鱼（Gasterosteus aculeatus）种群中，研究了婚色、寄生虫和体型对繁殖成功的影响。从林恩湖（美国阿拉斯加库克湾）收集到正在护卵的繁殖雄鱼，记录了它们的婚色、感染状态和体型。回归分析表明，在所测量的指标中，雄鱼体型是唯一能预测其自然繁殖成功的因素。
