The origin of this degree coincides with the Greek rival period of the late 18th through early 19th centuries. The Ph part means "love of wisdom" again a reference to the ancient Greeks. It has nothing to do the discipline of philosophy. The word Doctorate can be used also.
Quote:[S]ome believe that crown shyness is the end result of tree tips catching and snapping on those of their neighbors. The constant abrasion of growth nodules and bud tissue would explain why the trees' ability to grow laterally is clipped, and it’s thought that a tree's sensitivity to this mechanism of growth control is dependent on the species. The wind is also a significant factor in this instance, as heightened weather conditions will increase the likelihood of trees touching tips as they sway.
Quote:Plants and trees contain proteins that are sensitive to light known as photoreceptors, and one of the most common is phytochrome. This photoreceptor is able to detect red light which sunlight is abundant in, and research into many species has found that plants are capable of altering their growth as a means of shade avoidance. Through this mechanism, it would stand to reason that gaps could appear in the canopy as when crowding occurs the trees' outermost branches will receive less light as the branches of other trees cast shade.
