Explaining the population dynamics of two threatened prairie orchids through GIS modeling and next-generation sequencing.

The prairie fringed orchids, Platanthera praeclara and P. leucophaea, have undergone severe habitat reduction and fragmentation due to the cultivation and development of the prairies of North America. They are currently federally listed as threatened and have been the focus of several initiatives for recovery and reintroduction of viable populations. Despite widespread interest in their conservation status, there are still many unknowns concerning their biological relationship with pollinators and mycorrhizal fungi as well as the climatic and environmental factors affecting their populations. This study proposes to create a GIS model that integrates historical population data with several environmental variables in hopes of elucidating the primary factors affecting the orchids’ distribution and abundance in the state of Missouri. This study will also look at the soil microbiota community profile associated with these populations by implementing a metagenomic soil study. The symbiotic relationship that Platanthera orchids maintain throughout their lifetime with mychorrhizal fungi is putatively a determining factor in their successful establishment in otherwise adequate habitat. This initiative could establish a baseline representation of the biotic soil characteristics that should be taken into account when evaluating potential habitat for species reintroduction and management.
