EISENBERG: MAMMALIAN SPECIES OF ORDWAY-SWISHER PRESERVE CONCLUSION Responses of the small mammal populations to drought conditions highlights the dynamic aspect of the preserve's ecology. Population studies are a true challenge. A number of well motivated individuals have worked with some support from the staff on the Ordway-Swisher Tract: S. Brand, A. Kantola, and C. Gates were among the "originals." The following contributors to this volume address the questions that linger: (a) Ryser: What effects home range use by Didelphis virginiana?, (b) Jones: The habitat and effect of fire on Podomys floridanus, (c) HaySmith: The habitat of and effect of a drought on Neotoma floridana, and (d) Walker: The impact of high density raccoon, Procyon lotor, populations on other vertebrates living on the preserve.
