Pattern of Frost Damage and Recovery in Ohio Buckeye in Trelease Woods

ABSTRACT
Global heating causes many changes in weather standards including great temperature variability and more extreme temperatures. In this study we examined the alter and recovery in Aesculus glabra (Ohio buckeye) in Trelease Woods aft(prenominal) a new rhyme in the spring of 2007, potentially caused by world-wide warming. 1) If temperature and wind gradients directly affect the pattern of damage and recovery of Ohio buckeye, then as the outgo of Ohio buckeye from the forest edge increases the percent toss damage through by frost will decrease. 2) If the total flicker area available for photosynthesis in an Ohio buckeye directly affects its recovery from frost damage, then as percent leaf damage increases, recovery (based on percent flowerpotopy fullness, growth from 2007, and percent levelheaded buds) will decrease. Damage and recovery was measured in clx sub-canopy Ohio buckeye trees in four transects in Trelease Woods. Percent leaf damage in Ohio buckeye reduced as distance from forest edge increased. Percent canopy fullness reduced as leaf damage increased, mean growth from 2007 was not affected by leaf damage, and percent healthy buds decreased as percent leaf damage increased.



These results show that the centre of leaf damage done by a late frost is related to the distance from the forest edge and that the attendant recovery is also affected by the amount of leaf damage.
INTRODUCTION
Global warming causes increased variability and more extremes in temperature, which can cause damage to trees and change their phenology. Houle (2007) found that trees develop 2-6 days earlier in 2000 than they did in 1900, indicating that global warming is impacting the phenology of plants. This can affect plants by altering their growing seasons, which whitethorn have unknown impacts on the plants. Increased temperatures linked to global warming have also been associated with decreased frost resistance, which can lead to an increased amount of damage to trees buds (Bannister et al. 2005)....If you want to hold out a full essay, order it on our website: Orderessay
