If oak species in hammocks are more reliable producers, the distribution 

 of P. gossypinus and Ochrotomys nuttalli in hammocks at Ordway 

 might be partly due to the acorn supply. Competition could be one 

 factor restricting Podomys to sandhills when other rodents are present 

 in contiguous habitats. However, in sandhills and other habitats 

 elsewhere in Florida, P. floridanus P. gossypinus, and O. nuttalli are 

 sympatric (Packer and Layne 1991, Frank and Layne 1992).
