Plant functional traits may better explain liana species distributions

Plant functional traits may better explain liana species distributions

Plant functional traits may better explain liana species distributions Plant functional traits are morphological, physiological or phenological properties that affect plant growth, survival, and reproduction. They hold the promise to explain plant species distribution patterns. However, few studies have linked multiple traits to multiple niche …..
