Microphylls dominate vascular plant leaf sizes in Northeast China's Quercus mongolica forests. Leaf size spectra varied among trees, shrubs, and herbs, with microphylls prevalent across all sites.

Area of Science:

  • Plant ecology
  • Phytogeography
  • Botanical classification

Context:

  • Analysis of vascular plant leaf-size classes in a Quercus mongolica community in Northeast China.
  • Application of the Raunkiaer system for classifying leaf sizes.

Purpose:

  • To analyze leaf-size classes spectra of vascular plants in the Quercus mongolica community.
  • To investigate leaf edge characteristics.
  • To compare leaf-size spectra across different plant forms (trees, shrubs, herbs) and sites.

Summary:

  • Microphyll (45.4%) was the dominant leaf-size class, followed by compound leaves (23.1%) and mesophyll (22.6%).
  • Entire leaf margins were found in 22.3% of the studied plants.
  • Trees exhibited a higher mesophyll ratio compared to shrubs and herbs, which had the lowest ratio. Microphyll remained dominant across all investigated sites, irrespective of variations in latitude and altitude.

Impact:

  • Provides insights into the vegetation structure and adaptation strategies within the Quercus mongolica ecosystem.
  • Contributes to understanding plant community composition and distribution patterns in Northeast China.
  • Highlights the prevalence of microphylls and variations in leaf morphology across different plant life forms.
