Question

3. The number of annual rings in trees growing in temperate climates corresponds to the age of the trees. Scientists use tree ring analysis (dendrochronology) to age trees. By comparing patterns of tree ring size in cores from living trees with patterns in older dead trees and even samples of wood from old buildings, scientists have been able to piece together a chronology back thousands of years. Scientists in Europe are working collaboratively to develop a history of climate change for the last 10,000 years using tree ring analysis (dendroclimatology). How would regional climate changes affect the growth of trees? What features of secondary growth in trees would provide evidence for scientists to determine regional climate change? Why do you think this research is being conducted in temperate forests, but not tropical forests?

Answer 1

The growth of the trees will be affected by the regional climatic changes by the formation of secondary xylem in the phase of secondary tissues called wood, which allows studying them and according to this see the different seasonal variations through the annual rings

the studies are being carried out in temperate forests because the climatic variation is less noticeable in these areas than in the tropical ones
