This award provides funding for the PI to study life history evolution in marine systems by combining biogeographical, biochemical, morphological and paleontological approaches to examining egg size evolution in a family of marine bivalves relative to a major biogeographic event, the rise of the Central American Isthmus (CAI) at 2.8-3.1 million years ago. The rise of the CAI separated the Atlantic and Pacific oceans and isolated populations of previously-continuous species (known as geminate species pairs). The presence of multiple closely-related species offers a unique, replicated natural experiment that can shed light on evolutionary forces. The PI will study the egg size evolution of bivalves in the family Arcidae to determine the rate and timing of the evolution relative to the rise of the CIA. This research will provide the first descriptive data on egg size in the past, and will add a new approach for exploration of oceanic change and evolutionary response to geologic events. In addition, funding will support research experience for five undergraduate students.

该奖项通过将生物地理，生物化学，形态学和古生物学方法相结合，以研究海洋生物地理学家族中的卵大小的演变，相对于中美洲的兴起，中美洲的崛起（CAI）以2.8至310万年前的历史，该奖项为研究海洋系统的生活历史演变提供了资金。 CAI的崛起将大西洋和太平洋分开，以及以前连续物种的孤立人群（称为Geminate物种对）。多个紧密相关的物种的存在提供了独特的，复制的自然实验，可以阐明进化力。 PI将研究Arcidae家族中双壳类动物的卵大小演变，以确定相对于CIA的升高的演变的速率和时间。这项研究将为过去提供有关卵大小的第一个描述性数据，并将为探索海洋变化和对地质事件的进化反应添加一种新方法。此外，资金将支持五个本科生的研究经验。
