The basic idea is that slower growing species (or trees within species) will live longer because the reason they grew slower was better investment in defenses such as thick bark and defensive chemicals. The oldest trees thus have a bigger percentage of the slower growing trees and the young trees are a more random sample, with more fast growing individuals. This creates the bias and the hockey stick.MShttps://www.blogger.com/profile/06714540297202434542noreply@blogger.com
