	abstract = {Post-harvest loss of resources to microbial competitors affects a number of species of animals, and many of them have evolved behaviors that reduce the likelihood of such loss. We previously described the inhibition ofBacillus psychrophilus by dogwood fruits (Cornus drummondii), which can comprise a significant portion of the winter food cache of the eastern woodrat (Neotoma floridana). The present study is a further investigation of the ability of dogwood fruits to inhibit growth ofB. psychrophilus. Additionally, we tested the antimicrobial activity of dogwood fruits onEscherichia coli andStaphlococcus aureus. Results of our study indicate that fresh fruits inhibit the growth ofB. psychrophilus andS. aureus but notE. coli. However, fruits taken from woodrat dens after four and six months storage inhibited growth of all three species of bacteria. Further, the strength of inhibition increased over the test period. We suggest the presence of an inhibitor allows woodrats to compete effectively for a valuable and limited food resource.},

	abstract = {Change in microbial populations on three plant foods commonly stored over winter by eastern woodrats (Neotoma floridana) was assessed. It was expected that dogwood fruits (Cornus drummondii) would be affected by microbes to a greater degree than ash seed (Fraxinus pennsylvanica) or redbud seed (Cercis canadensis). Results revealed a change in microbial populations over time but dogwood fruit was no more liable to microbial infestation than seeds. One bacterial species was found in high number on all three food types while three species were found on only two of the three foods. Microbial populations from all three test items increased from November to January but March populations were not different from November populations. It is suggested that climatic factors help to control microbial populations on cache foods.},

	abstract = {<p>Responses of native aquatic bacteria to source and concentration of dissolved organic carbon was observed by using gradient plates. Dissolved organic carbon of prairie (grasses) or gallery forest (bur oak) origin was used as the carbon source in these observations. Bacteria isolated from sediments in the grassland reaches of a prairie stream showed growth only on grass leachates. Bacteria isolated from the gallery forest reaches of the same stream were able to grow on plates made from either source of leachate. The differing quality, quantity, and rate of supply of these dissolved organic carbon sources should select for variation in the baterial assemblages</p>},
