WebJun 15, 2024 · Specifically, most work on ErM effects on forest C and N dynamics has been conducted in boreal forests dominated by EcM trees. Of the 25 studies, about two-thirds were from boreal forests (16 out of 25), with the remainder from temperate forests (nine out of 25) and zero from tropical forests (Tables 2, S3). Forest disturbances are events that cause change in the structure and composition of a forest ecosystem, beyond the growth and death of individual organisms. Disturbances can vary in frequency and intensity, and include natural disasters such as fire, landslides, wind, volcanic eruptions, rare meteor impacts, outbreaks of insects, fungi, and other pathogens, animal-caused effects such as grazing and trampling, and anthropogenic disturbances such as warfare, logging, p…
