These studies aim to understand how flexibility in parenting behavior and effects of parenting on offspring behavior and physiology (parental effects) influence evolutionary patterns using the threespine stickleback fish as a model. Threespine stickleback originated in marine environments and have colonized freshwater multiple times. In some cases, the exact age of freshwater populations is known, providing a unique opportunity to study not only the mechanisms underlying how variation in parental care influences offspring in multiple environments, but also examination of the speed at which these changes are occurring. Current ecosystems and habitats are rapidly changing in response to climatic and anthropogenic influences, and the proposed series of studies provides an opportunity to observe how parental behavior and parental effects facilitate rapid, adaptive evolution. While many studies of parental effects, including on humans, focus on the effects that mothers have on their offspring, in threespine stickleback, the father is the sole provider of parental care. Therefore these studies will provide insight into how fathers influence their offspring, and will determine whether the influence of mothers and fathers on offspring is similar or different.

这些研究的目的是了解如何灵活的养育行为和养育子女的行为和生理（父母的影响）影响进化模式使用threespine棘鱼作为模型。 三棘鱼起源于海洋环境，并多次在淡水中定居。 在某些情况下，淡水种群的确切年龄是已知的，提供了一个独特的机会，不仅可以研究父母照顾的变化如何影响多种环境中的后代的机制，而且还可以研究这些变化发生的速度。 目前的生态系统和栖息地正在迅速变化，以应对气候和人为影响，拟议的一系列研究提供了一个机会，观察父母的行为和父母的影响如何促进快速，适应性进化。 虽然许多关于父母影响的研究，包括对人类的研究，都集中在母亲对后代的影响上，但在三棘鱼中，父亲是父母照顾的唯一提供者。因此，这些研究将提供深入了解父亲如何影响他们的后代，并将确定母亲和父亲对后代的影响是相似还是不同。
