A Comparison of Natural and Manmade Fragmentation Effects within Three Pollination Networks of Erigeron.

Understanding how fragmentation affects pollination mechanisms and gene flow in plant species is a critical issue to further limit the "island effect" with which many of our military bases are challenged. This can have wide application for resource management on military bases and other refuges that are islands, surrounded by growth and development. This study, funded by the Basic Army Research Program, investigates pollination network properties in relationship to a genetic analysis for three species of Erigeron affected by fragmentation. We applied network science approaches to understand how plant species subjected to fragmented habitat have adapted pollination network strategies to ensure adequate gene flow. Our study will focus on three species of Erigeron (Fleabanes); one rare, endemic plant adapted to naturally sparse cliff wall habitat (E. lemmonii) compared to two others (E. arisolius and E. neomexicanus) adapted to more diverse habitat conditions. Pollination networks have been constructed and analyzed within network science using UCINET. Additionally, this research has revealed new botanical information about the rare, endemic Erigeron lemmonii and its pollination biology.
