Essentially, from what I understand right now, the phyllosphere is the community of life that revolves around the leaves of trees and plants.
Most of what I could find online about the phyllosphere relates to microbiology, but to be clear, it includes the macroscopic organisms, like slugs, beetles, aphids, and more in it, too.
Phyllosphere organisms, interaction and functions
My description for this video:
This video is a brief overview of the microbiology of the phyllosphere (plant leaf biome).
Exploring the temperate leaf microbiome
From the video description:
"The aerial surfaces of plants, the phyllosphere, harbors a diverse community of microorganisms. The increasing awareness of the potential roles of phyllosphere microbial communities calls for a greater understanding of their structure and dynamics in natural and urban ecosystems"
Nice that you are really engaging with the topics. I am a bit of a word geek and delight in checking out any word that I don't know. You probably already have had a look but if you haven't check out the glossary at the back. My original intention was to include words that may be unfamiliar generally in the manuscript, but then it kind of took on a life of its own. I was pleasantly surprised that the publishers allowed this to run, almost unmolested !
