Overview

Randomized trial investigates seed production impacts on biomass in European beech forests, suggesting climate factors dictate growth patterns.

Key Points

  • This research aimed to determine the relationship between seed production and per-seed investment in European beech trees, focusing on how climate influences this dynamic.
  • Quantified individual seed production and seed mass across 2792 trees from 123 populations.
  • Analyzed protein and lipid content in seeds from 35 populations.
  • Assessed variation in seed characteristics relative to climate factors.
  • Seeds from high-seeding years were 14% heavier than those from low-seeding years, indicating no seed size-number trade-off.
  • Protein content decreased by 31% with increased seed production, while lipid content increased by 14%.
  • Lowest seed mass and protein content were observed at climatic range margins, 28% and 32% lower than at the climatic center.
