Biomonitoring with environmental DNA: Oak trees, forest fire, and the impact of fire in the Holocene.

Forests have complicated microbial communities that may vary with location, history, and plant community structure. The emerging environmental DNA sequencing (metabarcoding) technique is helping us understand more about the phylogenetic, genetic, and functional diversity that shapes forest communities and ecosystem services. In California, fire is occurring at increasing frequency, but researchers are still grappling with the meaning of eDNA data for conservation of fire-prone systems.
We advanced a terrestrial eDNA monitoring program to understand the relationship between plants and microbes and animals, including holobiomes. Here I present three research vignettes demonstrating the following: (1) Valley oak tree genotypes influence their soil and leaf holobiomes. (2) Klamath mountain forests have strong plant-microbe relationship where fire only has limited lasting effects.
(3) Plant-animal communities potentially altered by fire can be tracked through the Holocene with environmental DNA.
