Variation in tree phenology in response to recent climatic changes
|
The response of trees and tree species to climatic changes will be essential to understanding how forested ecosystems will be impacted by projected global climate change. The combined response of tree phenology and growth patterns could be a strong indicator of the potential adaptation of tree individuals and species to future climatic changes, but have rarely been considered in conjunction. Climate responses of tree genera (e.g., oaks, hickories) will likely vary greatly among species, and responses of these species may be driven by within-species variation. The latitudinal origin of a species or individual will likely have a strong influence on its response to climate change. Species or populations from southern parts of a genus/species range may be better adapted to future climates, which will likely feature warmer, drier conditions and earlier onset and longer duration of growing season.
An improved understanding of the relative importance of species and individual origin on tree responses to climate could aid in assessing the scientific case for assisted migration. Research focused on inter- and intra-specific variation in tree phenological and growth responses to recent climate change is being conducted in the collections of The Morton Arboretum.
