Overview

Exploration of habitat preferences and nutrient acquisition in ectomycorrhizal trees reveals their role in community assembly.

Key Points

  • The research investigates how nutrient preferences across growth stages affect tree community composition.
  • Established 1200 seedling quadrats in six 1-ha plots
  • Monitored seedling survival and growth annually from 2008 to 2022
  • Surveyed sapling and adult performance within a 50-ha plot from 2016 to 2021
  • Assessed resource preferences for nitrogen and phosphorus across ontogenetic stages
  • AM trees showed consistent preferences for inorganic nitrogen and negative associations with organic nitrogen.
  • ECM seedling preferences shifted towards inorganic nitrogen; saplings preferred inorganic phosphorus.
  • Adult ECM trees' distribution was negatively correlated with soil organic phosphorus.
