The Drosophila of Jackson Hole, Wyoming-A Taxonomic and Ecological Survey

In the time at our disposal a preliminary study of the species of the genus Drosophila and their ecological distribution in the Jackson Hole area was undertaken. This project was made possible through a grant from the Jackson Hole Wildlife Park and constitutes a small part of the survey of the flora and fauna of this region being carried oni at the Wildlife Laboratory in the Park. The author wishes to thank the directors of the Wildlife Park for this grant and Mr. James R. Simon and Dr. Robert K. Enders for the courtesies extended during his stay at the laboratory. Miss Rada Demerec served as research assistant and it is a pleasure to acknowledge her efficient help in the project. Large samples of populations of two of the native species have been saved and will be used in the studies on the genetics of populations which the author has undertaken.
