Invasions by aquatic invasive species (AIS) are a leading environmental problem. A key objective of governments is development of early detection screening programs for AIS. My research is dedicated to development of effective molecular screening programs that can identify AIS at exceptionally low abundances in nature. We will utilize next generation sequencing on samples obtained from ports and ballast water of ships to determine presence of very rare native and alien species. We will also study relationships between species richness (colonization pressure) and species abundance (propagule pressure) in port and ballast samples to determine the relative importance of these two parameters in facilitating invasions. We also will assess how colonization pressure and propagule pressure vary temporally in vessels conducting trans-Pacific or trans-Atlantic journeys, which may allow us to determine the relative importance of these two parameters to invasion success, and establish invasion risk to recipient ports in western and eastern Canada.

水生入侵物种（AIS）的入侵是主要的环境问题。 政府的一个关键目标是开发针对AIS的早期检测筛查计划。 我的研究致力于开发有效的分子筛选程序，这些程序可以在自然界中识别出异常低的丰度AIS。 我们将在从船舶的端口和压载水获得的样品上使用下一代测序，以确定存在非常罕见的本地和外星物种的存在。 我们还将研究港口和压载样品中物种丰富度（定植压力）和物种丰度（繁殖压力）之间的关系，以确定这两个参数在促进入侵中的相对重要性。 我们还将评估进行跨太平洋或跨大西洋旅程的血管中的定殖压力和繁殖压力如何变化，这可能使我们能够确定这两个参数对入侵成功的相对重要性，并确定对加拿大西部和东部的接收者端口的入侵风险。
