plans to conduct experiments to understand the role of sensory cues
that nectar bats use to detect flowers. | |
Lindsey Dennison B.S.

For her master's thesis, she is investigating the role of vision in flower detection by Anoura caudifer, a neotropical nectar bat.

Muchhala Lab Alumni | |
Dr. Rieka Yu Rieka is interested in the effect of habitat destruction on pollination systems. For her Ph.D. she studied how pollinators differ in their response to habitat degradation and in the pollination services they provide, and how this can influence plant fitness. She is now completing a fellowship with the Missouri Science and Technology (MOST) Initiative. | |
Jordan Hathaway B.S. Saint Louis University, USA Jordan
is interested in insects and pollination systems. For his master's thesis, he examined the factors which
influence pollination success and fruit production within urban
orchards throughout the St. Louis metropolitan area. He is now working with Dr. Christine Edwards in the Missouri Botanical Garden. | |
Daniel Tarazona-Ocaña B.S. Universidad Nacional Agraria La Molina, Peru Daniel
is interested in the taxonomy, wood anatomy and uses of the Peruvian
arboreal flora. For his Master's degree, co-advised by Dr. Mónica Carlsen, he studied the taxonomy of a monophyletic section of Anthurium. He is now working as a data processor with the Missouri Botanical Garden.

Shawn Kelley (M.Sc. Student) B.S. University of Missouri - St. Louis, USA Shawn is interested in plant evolutionary biology and systematics. For his Master's degree, Shawn revised the genus Trilepisium in Madagascar. This included descriptions of new species, a bifurcating key, and updated descriptions and ranges. Additionally, he studied the history of diversification and dispersal within the genus. spkvd6 [at] mail.umsl.edu | |
Dr. Juan Moreira-Hernández
M.Sc. Universidad de Costa Rica, Costa Rica Juan is interested in tropical plant evolution and diversification and the evolutionary ecology of vertebrate pollination systems. For his PhD, he studied how interspecific pollen transfer influences the evolution of reproductive isolation and patterns of hybridization among bat-pollinated Burmeistera in Ecuador. Juan is now a postdoctoral fellow with Dr. Oystein Opedal at Lund University. juan.moreira [at] gmail.com | |
Alex Lascher-Posner B.S. University of California, San Diego, USA Alex
studied the influence of pollinator behavior on pollen dispersal in two
disparate systems: bat pollination of tropical plants and insect
pollination of milkweeds (Asclepias)
in Missouri. Results of the former showed that bat grooming can
impact pollen transfer, and female bats tend to groom much more
frequently, while results of the latter found that different insects
differ in their effect on geitonogomous (within-plant) pollen transfer. aelwqb [at] mail.umsl.edu | |
Dr. Diana Gamba For her PhD, Diana explored the mechanisms that lead to disruption of gene flow and allopatric speciation among flowering plants. For multiple species in northern Ecuador, she analyzed data on the effects of asynchronic flowering phenology and pollinator shifts on population genetic structure. Diana is now a postdoctoral fellow with Dr. Jesse Lasky at PennState University; find out more about her research here. dlgtk5 [at] mail.umsl.edu | |
Brock Mashburn Brock
is interested in plant evolutionary biology, systematics, biogeography,
and the application of these fields to conservation actions. For his
Masters degree, he updated the monograph of the Burmeistera
of Ecuador which was published in 1981. This included updating species
ranges and descriptions, describing new species, and writing a key. He is currently a Ph.D. student with Dr. Christine Edwards at Washington University in St. Louis. btmfkb [at] mail.umsl.edu | |
Dr. Justin Bagley
Ph.D. Brigham Young University, USA Justin is an evolutionary biologist whose interests include phylogeography, population genomics, adaptation, species delimitation, and integrative taxonomy.
