Changes of leaf functional traits in karst rocky desertification ecological environment and the driving factors

Global Ecology and Conservation, 2020
Karst rocky desertification (KRD), a degraded land form, has seriously damaged the balance and stability of the ecosystem. Plant functional traits reflect the response and adaptation of plants to the growth environment. However, little is known about the

Community Assembly Mechanism of Woody Plants at Different Successional Stages in Karst Areas Based on Functional Traits and Phylogeny. [PDF]

Ecol Evol
This study reveals a shift in woody plant community assembly from competitive exclusion in early succession to habitat filtering in later stages within karst areas. Environmental distance (80.54%) contributed significantly more than geographical distance (9.95%), providing strong quantitative evidence that niche processes, particularly habitat ...
