Nancy B. Simmons
Chair, Curator-in-Charge (Mammalogy), Associate Curator
Ph.D., University of California at Berkeley, 1989 "Phylogeny and Systematics of Multituberculate Mammals"
Dr. Simmons specializes in the morphology and evolutionary biology of bats (Chiroptera). Her current research projects include:
Higher-level relationships of bats based on combined analyses of morphological and molecular data There are more than 1000 living species of bats, but much remains to be learned about their evolutionary relationships. Together with several collaborators, Dr. Simmons is developing a data matrix of morphological characters scored in species representing all major clades of bats. These data will be combined with DNA sequence data to develop a robust higher-level phylogeny for Chiroptera.
Evolution of echolocation Working with an expert on echolocation behavior, Dr. Simmons is developing a method for coding features of echolocation calls for phylogenetic analysis. They hope to use these characters to help better resolve evolutionary relationships among microchiropteran bats, and to use phylogenies to help form hypotheses about how echolocation has evolved in different lineages.
Bat species of the World a taxonomic and geographic reference Dr. Simmons is writing the Chiroptera section for the next edition of Mammal Species of the World. This compendium will contain a complete classification of bats from the level of order to subspecies, provide taxonomic notes on every species (including synonymies with names and dates of authorship for all names), geographic range data, and conservation status of every species. Publication is expected in 2003.
Faunal inventory in Amazonian Peru Working with Museum Curator Robert Voss and an ethnozoologist, Dr. Simmons is conducting an inventory of mammal diversity at a site in the lowlands of Amazonian Peru.
