HABITAT USE AND HOME RANGES OF PODOMYS
 FLORIDANUS ON THE ORDWAY PRESERVE


 Cheri A. Jones'



 ABSTRACT


 I examined habitat use and home range size ofPodomysfloridanus on the Ordway Preserve, where
this species is most common in high pine communities with gopher tortoises (Gopherus polyphemus). These
communities are subjected to prescribed bums in order to prevent invasion of woody species. Populations of
Podomys appeared more stable on burned sites than on unburned areas. Home ranges did not alter after
prescribed bums and little or no fire-related mortality was indicated. Mean home ranges were 2601 m2 for
35 females and 4042 m2 for 40 males. Individuals who survived more than one year on the sandhill utilized
the same set of burrows each season. Home ranges of adult females did not overlap, suggesting intra-sexual
territoriality.


 RESUME


 Examine el uso de habitat y tamailo del Ambito de hogar de Podomysfloridanus, en la Reserva
Ordway, donde esta especie es mas comnn en comunidades de pino alto con tortugas excavadoras
(Gopheruspolyphemus). Estas comunidades estan sujetas a quemas prescritas con el objeto de prevenir la
invasion de species leflosas. Las poblaciones de Podomys parecieron ser mis stables en sitios quemados
que en areas no quemadas. Los Ambitos de hogar no fueron alterados despu6s de las quemas prescritas y se
detect muypoca o ninguna mortalidad relacionada con el fuego. El tamafio medio de los Ambitos de hogar
fue 2601 nm para 35 hembras y 4042 m para 40 machos. Los individuos que sobrevivieron mAs de un afio
en las tierras altas arenosas, utilizaron el mismo grupo de cuevas en cada estaci6n. No hubo superposici6n
en los Ambitos de hogar de hembras adults, lo cual sugiere territorialidad intrasexual.


 INTRODUCTION


 The Florida mouse, Podomys floridanus, is one of the characteristic rodents of the
 Ordway Preserve. Here P. floridanus is known from high pine habitats (i.e. longleaf pine
 sandhills) and from ecotones between high pine and hammock or high pine and old pasture
