Recent Topics Posters Jabaily , Rachel Schmidt [1], Bodine, Erin N. [2]. Bromeliaceae Life History Evolution. Bromeliad taxa differ in life history attributes, including lifetime attempts at sexual reproduction (a single vs. multiple times), and relative ability to produced asexual clones, or pups. The diversity of life history across the Bromeliaceae provides a rich model for comparative study, and how life history evolves and impacts conservation of various bromeliad taxa is unknown. The bromeliad research and horticultural communities also lack consistent understanding of life history terminology and a consistent life history type has not been ascribed to most taxa. Semelparity, or a single and subsequently lethal attempt at sexual reproduction via flowers with no pupping, has evolved repeatedly within the Bromeliaceae. The majority of taxa are iteroparous, producing inflorescences repeatedly across the lifespan of the genetic individual, but the number, timing, and anatomical origin of pups differ between taxa. The talk will overview models of life history evolution as applied to bromeliads. Ongoing experimental data from multiple exemplar taxa, and field data from semelparous and iteroparous Tillandsia taxa in Florida and semelparous Puya raimondii in Bolivia, will be discussed. Mathematical modeling utilizes these data to provide a framework to theoretically and quantitatively explore and test the evolutionary drivers of different life history strategies.
