“Does Emerald Ash Borer Infestation Alter Ash Phloem Microbial Communities over Time?” Read the article by Andrew J. Mann et al. to find out: https://doi.org/10.1094/PBIOMES-06-25-0046-R #plantmicrobiome #microbiome #endophytes #emeraldashborer
Fig. 1. A sampling overview diagram. Trees are organized into infestation categories based on the following criteria. A: Emerald ash borer (EAB)-infested phloem in the bottom 2 m of the tree during the entire study period. B: EAB-infested phloem is absent in the bottom 2 m of the tree at the start of the study but present at the end of the study. C: Trees show symptoms of EAB infestation in canopy but no EAB-infested phloem in the bottom 2 m of the tree. D: No symptoms of EAB infestation. The orange in the figure provides a simplified representation of the locations of EAB galleries within the tree in each infestation category. The control phloem samples are labeled as CP, uninfested phloem before EAB reached the base of the tree is labeled as UP Before, uninfested phloem after EAB reached the base of the tree is labeled as UP After, infested phloem is labeled as IP, frass is labeled as F, and the larval samples are labeled as La.

Many more ash trees down in the forest yesterday.

If you see a dead tree with strange artsy scribbles cut in the bark that’s not a bored destructive teenager with pocket knife—it’s the feeding channel of a devastating #EmeraldAshBorer. An invasive beetle. Eating ash trees alive from the inside.
