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

The loss and fragmentation of natural habitats by human activities are pervasive interrestrial ecosystems and the main cause behind current biodiversity loss. 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. Few studies have investigated how plants evolve with pollination networks in fragmented habitats - one of the most influential interactions affecting plant demography and genetic viability. This on-going study, funded by the Basic Army Research Program, is a pioneering effort to study network properties of pollination networks in relationship to a genetic analysis for 3 species of Erigeron affected by fragmentation. We will be applying network science approaches to understanding 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 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.
