خلاصه	Dendrochronology is the science of dating and analyzing tree rings to reconstruct past climatic conditions, chronologies, and tree growth patterns. Pioneered by Andrew Ellicott Douglass in the early twentieth century and formalized by Fritts and colleagues, dendrochronology enables precise dating of historical wood samples and generates millennial-length climate records, becoming indispensable for paleoclimatology, archaeology, and forest ecology.	Allometric equations predict tree above-ground or total biomass from easily measured tree dimensions—typically diameter at breast height (DBH), height, and wood density. Grounded in biological allometry (scaling laws) and codified by Chave, Niklas, and others, allometric equations are essential tools for rapid biomass assessment without tree harvesting. Used globally for carbon accounting, yield estimation, and ecosystem characterization.
