1. Interactive, probabilistic identification key for the Espeletia species from páramo de Sumapaz: Espeletia is a genus of plants endemic to the northern Andes, largely restricted to high elevation ecosystems known as “páramos.” Unfortunately, species identification can be difficult in Espeletia, in part because these species diverged recently and hybridize frequently. The student participating in this project will manipulate data, write a key for species identification and perform computer simulation experiments to test the key.

2. Building a botanical foundation for sustainable agriculture: characterizing patterns of variation and covariation in herbaceous perennials: This project aims to systematically evaluate wild, perennial herbaceous and shrubby grain, legume, and oilseed species for inclusion in pre-breeding and domestication programs with the goal of developing new, environmentally friendly, agricultural species. The student will help characterize traits (i.e. plant size and growth rate, flowering time and duration, flower morphology, pollinator visitation, plant architecture, leaflevel physiology and seed production) and analyze relationships among traits to help inform a predictive model.

  1. Zingiberales diversification in the tropics: Plants in the Zingiberales (i.e. gingers, bananas, and relatives) are hyperdiverse in the American tropics but not in the Asian continent, where the group originated. This project will test whether these differences in number of species are due to changes in diversification, speciation or extinction rates dependent on their geographic distribution.
  2. Climatic diversification of the genus Croton in AfricaCroton is a diverse species group distributed around the globe with 50 species distributed in continental Africa. Using morphologic and climatic data this project will explore multiple macroecological questions such as the relationship between leaf morphology and climate.
  3. Global Genome Initiative in Gardens: The living plant collections at the Missouri Botanical Garden harbor a vast amount of diversity. This project aims to understand how much phylogenetic diversity is currently represented at the Garden by analyzing DNA sequences of the species in the collections.
