Haiku - Forest for the Trees

Tree climbing a vine


Haiku challenges
Minimal (1) structured verses
Infinite meaning







Results: Single tree vine richness increased with increasing host tree DBH (2) and differed significantly among host species. For climbing vines, the ratio of variation in subplot presence explained by tree species and by environmental variables was ca. 4:1 (in the most disturbed logged plots slightly lower), for free standing vines this ratio varied from 1:2 in the most disturbed logged plots to 9:1 in reserve plots, while a ratio of ca. 1:1 was found for all plots analyzed together.

Conclusion: Different tree species have different probabilities of being infested by vines. Vines see both the forest and the trees; the environment is more important in earlier developmental stages, properties of individual trees become more important from the time vines start to climb. (3)
__________________________
(1) minimal, minimum - These adjectives have subtle differences in meaning. Minimal means "extremely small in number, amount or degree ... and not worth worrying about": with minimal support, minimal objectives, minimal amount of pain. Minimum means "the smallest number, amount or degree that is possible, necessary, acceptable or lawful to have": Of any one in his family, he had minimum contact with his father. Minimum wage. Minimum payment. Reference by clicking here

(2) DBH - diameter at breast height. I knew this without having to look up the abbreviation - learned in one of my plant ecology classes over 30 years ago. My instructor, Bill Chilcote, was on my graduate committee - I had three of his courses. I saw a few months ago that he had passed away in 2006, the year I left Corvallis for the east coast.
