Temperature Determines Symbiont Abundance in a Multipartite Bark Beetle-fungus Ectosymbiosis

  title={Temperature Determines Symbiont Abundance in a Multipartite Bark Beetle-fungus Ectosymbiosis},
  author={Diana Lee Six and Barbara J Bentz},
  journal={Microbial Ecology},
In this study, we report evidence that temperature plays a key role in determining the relative abundance of two mutualistic fungi associated with an economically and ecologically important bark beetle, Dendroctonus ponderosae. The symbiotic fungi possess different optimal temperature ranges. These differences determine which fungus is vectored by dispersing host beetles as temperatures fluctuate over a season. Grosmannia clavigera is the predominant fungus carried by dispersing beetles during… CONTINUE READING
