Project: The genus Anthurium in northern Central America – morphology, DNA, ecology and evolution. Monica Carlsen is one of the specialists in the Araceae family at MBG. Araceae are a diverse tropical plant family with ca. 3,000 species, highly valuable as ornamental plants and flowers. Her research focuses in understanding the rapid radiation of the species-rich (ca. 900 species) Neotropical genus Anthurium (“flamingo” or “wax flower”), integrating revisionary taxonomical studies, molecular phylogenetics, fossil calibrations and dating, biogeography and species distribution modeling. Several interesting biogeographic patterns have been discovered in Anthurium, one of them involving species restricted to northern Central America (Mexico to Honduras). These species (approx. 60) are divided in two groups (lineages), which differ in terms of diversity, morphology and ecological preferences. The main objective of this project is to perform a detailed study of these species in order to understand the evolutionary history of Anthurium in the area. With the mentor’s guidance, students will learn to morphologically describe Anthurium species, generate molecular data to analyze species relationships, and produce ecological niche models. This is a multidisciplinary project, therefore the student(s) could choose to be involved in all or just some of the following activities: sorting out species of Anthurium, use of herbarium (dried) and living collections, describing basic morphological features of species, developing and using Lucid interactive key technology, DNA extraction, PCR amplification and sequencing, and species distribution modeling using specimen’s collection localities and climatic variables. A maximum of two students could be associated with this project. Student(s) will assist Dr. Carlsen in the preparation of a manuscript and be co-author(s) for a publication based on the results of this project.
