0073542Waaland & WhitmerThis project focuses on the population dynamics and genetics of an annual marine plant species, a kelp commonly known as the Sea Palm (Postelsia palmaeformis). The Sea Palm is an annual alga that grows in the Pacific Northwest. It appears in the early spring and dies off each fall. Population locations and sizes vary dramatically from year to year. This research studies how these populations are related along the coast and through time. Individuals' locations have been mapped using computerized surveying equipment over the last two years. Concurrently, tissue samples have been collected for genetic analysis. DNA markers will be used to reveal the relationship of individuals found in a single year within a population, between two or more populations, and between populations from one year to the next.Studying population dynamics through space and time allows us to understand how populations are interconnected. This understanding provides insight into what is otherwise unknowable for many organisms, namely where individuals come from and how they interact with each other. DNA markers allow us to estimate the genetic diversity of populations (i.e., the "genetic health" of a species). Results of such studies are of fundamental scientific interest and may be applied in managing and conserving living resources in coastal regions.

[73542] waaland & whitmer这个项目的重点是一种一年生海洋植物物种的种群动态和遗传学，这种植物通常被称为海棕榈（Postelsia palmaeformis）。海棕榈是一种生长在太平洋西北部的一年生藻类。它在早春出现，每年秋天死亡。人口的分布和规模每年都有很大的变化。这项研究研究了这些种群在沿海地区和时间上的关系。在过去的两年里，个人的位置已经用计算机测量设备绘制出来了。同时，已收集组织样本进行基因分析。DNA标记将用于揭示一个种群内单个年份内发现的个体之间的关系，两个或多个种群之间的关系，以及种群之间从一年到下一年的关系。通过空间和时间研究种群动态可以让我们了解种群是如何相互联系的。这种理解为许多生物提供了不可知的见解，即个体从何而来以及它们如何相互作用。DNA标记使我们能够估计种群的遗传多样性（即一个物种的“遗传健康”）。这些研究的结果具有基本的科学意义，可用于管理和保护沿海地区的生物资源。
