Genetic Diversity and Spatial Genetic Structure ofGuzmania monostachia(Bromeliaceae)in Florida.

Bromeliaceae are aneotropical plant family consisting of around 3140 species in eight traditional subfamilies. The subject of my research is the genus Guzmania Ruiz & Pav.,specifically the Florida native species Guzmania monostachia(L.) Rusbyex Mez. In 1989, an invasive bromeliad-eating weevil, Metamasius callizona Chevrolat (Coleoptera: Curculionidae),was introduced into Florida from Mexico, endangering most of Florida’s native bromeliads,including G. monostachia. In this talk, I will introduce my research on the population geneticsand genetic structure of G. monostachia in Florida and present the phylogenies of Guzmania that I have constructed. Additionally, I will present the findings of my fieldwork that will take place in the early summer. The populations I will be visiting are remote, and have not been checked onin several years, so my fieldwork will not only generate the plant material needed for my molecular analyses, but also provide insight into the current health of G. monostachia populations in Florida.This research is desperately needed to assess the full impact of M.callizona on G. monostachia populations in Florida, as well as to identify sources of population-level diversity that may be important for future pest-mitigationand targeted conservation efforts. Conservation of bromeliads is critical because the water collected in their leaf bases, known as a “phytotelmata”, sustains life for a variety of unique aquatic organisms, and also serves as an important source of hydration for animals during the dry winter season.
