GEOG 101 Lecture Notes - Lecture 30: Thuja Occidentalis, Swampy, Environmental Factor
Document Summary
Most species show maximum growth within a specific range for an environmental factor. Beyond this range, growth declines due to: The viability of an individual plant in relation to changing conditions along an environmental gradient. Going beyond the limits of a range of a factor means death for the plant. The relationship between viability of a species and the individual members of that species along an environmental gradient. Range of conditions in which growth, survival and reproduction of a species is. Optimal conditions in absence of competition, predation, disease. Range of conditions in which species is most successful. Can"t compete with maple or beech species. Environmental factors that influence plant growth and reproductive success: Direct relationship between sunlight intensity and the rate of photosynthesis. Black oak leaves in shade and progressively higher in the canopy. Leaves at the top of the tree (with more sun exposed) are smaller and more lobe-ier.
