title: Microfungal Community Changes in Rodent Food Stores over Space and Time.
abstract: > Abstract This paper reports the changes over time in the microfungal communities that inhabit three rodent species' food stores at two climatically different locations. Results reveal that microfungal diversity values calculated from above-ground food stores are highest in the more commonly disturbed portions of the rodent dens. Interactions among food-inhabiting microbes and between the rodents and food-inhabiting microbes also appear to influence the microfungal communities within the rodent dens. For example, our data suggest that transport by animal vectors, and not by air currents, is more effective at dispersing microbial propagules. Furthermore, although fungal communities inhabiting food stores within dens varied in composition and diversity over time, standardized substrates (sorghum seeds) simultaneously placed within the food stores converged in microfungal composition the longer they were left within the dens. We hypothesize that animal vectors, including rodents, make neighboring fungal communities more alike by introducing similar communities of microbes, which in turn initiate a cascade of biological interactions that, over time, result in similar microfungal communities inhabiting newly stored food items.http://link.springer-ny.com/link/service/journals/00248/bibs/38n1p79.html
