本文研究了四斑尼克鱼的胴体大小和雄鱼的存在对窝卵数的影响。雄性的存在增加了离合器的大小，并提高了雌性生产替代离合器的能力。窝卵数也与胴体大小有关。对于大多数胴体尺寸，窝卵数与窝卵数之间呈负相关。我们的结论是N. quadripunctatus是潜在的iteroparous和假设，生殖能量是预留的育雏失败。
The effects of carcass size and male presence on clutch size in Nicrophorus quadripunctatus were examined. Male presence increased clutch size and improved the female's ability to produce replacement clutches. Clutch size was also related to carcass size. There was a negative correlation between number of clutches and clutch size for most carcass sizes. We conclude that N. quadripunctatus is potentially iteroparous and hypothesize that reproductive energy is reserved for brood failure.
