      abstract = {<p>Interactions between microbial symbionts influence  their demography and that of their hosts. Taylor’s power  law (TL)–a well-established relationship between population  size mean and variance across space and time–may help to  unveil the factors and processes that determine symbiont  multiplications. Recent studies suggest pervasive  interactions between symbionts in Drosophila melanogaster.  We used this system to investigate theoretical predictions  regarding the effects of interspecific interactions on TL  parameters. We assayed twenty natural strains of bacteria  in the presence and absence of a strain of yeast using an  ecologically realistic set-up with D. melanogaster larvae  reared in natural fruit. Yeast presence led to a small  increase in bacterial cell numbers; bacterial strain  identity largely affected yeast multiplication. The spatial  version of TL held among bacterial and yeast populations  with slopes of 2. However, contrary to theoretical  prediction, the facilitation of bacterial symbionts by  yeast had no detectable effect on TL’s parameters. These  results shed new light on the nature of D. melanogaster’s  symbiosis with yeast and bacteria. They further reveal the  complexity of investigating TL with microorganisms.</p>},
