The functional characteristics of plants may better explain the distribution of vine species.

Functional characteristics of plants are morphological, physiological, or phenological characteristics that affect plant growth, survival, and reproduction. They have the potential to explain the distribution patterns of plant species. However, few studies have linked multiple properties to multiple niche dimensions (that is, light, water, nutrients).


In a study published in Ecolo gear, Xishuangbanna Tropical Botanical Garden (XTBG) researchers, 18 leaves, stems, and Root characteristics From 29 predominant Liana species, we have linked them to light. waterNiche dimensions of the species’ nutritional surface in the 20-hectare Xishuangbanna Forest Dynamics Plot in Yunnan Province, southwestern China.

Researchers asked how Liana’s traits are related, what plant strategies can be distinguished, and whether different traits form niches of different species.

Lianas showed two orthogonal characteristic spectra. Water saving Secondary spectrum in tissue softness and rapid water acquisition, and nutrient and carbon acquisition.

Liana species with more acquired trait values ​​occupied a higher light and nutrient niche, but different traits were important in different niche dimensions. Interestingly, each spectrum was conservative and acquired. Partially reflects the niche paradigm, but at the same time, these two spectra are independent of each other.

They found that different functional traits form different niche dimensions, and multivariate trait strategies also play a role in shaping the distribution of Liana. This indicates that Liana species with more acquired property values ​​(softer tissue, more water use) can take advantage of these conditions to control the niche of high soil resources.

In addition, they found that the species niche was determined not by the plant’s strategy (that is, the overall trait syndrome), but by the underlying factors (that is, the individual traits).

“Therefore, traits may be a better explanation than the abundance of local plants. seed “Distribution along the gradient of resource availability and its existence,” said Zhang Jiaolin, principal investigator of the study.
