Adjacent populations of Nassarius pauperatus differ significantly in how hungry their members are. The numbers of eggs and egg capsules produced are positively correlated with how hungry members of a population are, but the average number of eggs per capsule is negatively correlated with hunger. These results were confirmed in a laboratory experiment using two groups from the same population maintained with different levels of food.The significance of this behaviour is discussed and the hypothesis proposed that the flexibility of reproductive patterns is correlated with dispersive ability.
相邻的贫拟织纹螺种群在其成员的饥饿程度上存在显著差异。所产卵和卵囊的数量与种群中成员的饥饿程度呈正相关，但每个卵囊中卵的平均数量与饥饿程度呈负相关。这些结果在一项实验室实验中得到了证实，该实验使用了来自同一群体的两组螺，并给予不同水平的食物。文中讨论了这种行为的意义，并提出了生殖模式的灵活性与扩散能力相关的假说。
