[Ordination analysis on relationship between bryophyte distribution and climatic factors]

Area of Science:

• Bryology
• Phytogeography
• Ecology

Context:

• Moss distribution patterns are influenced by climatic factors.
• Understanding these relationships is crucial for biodiversity conservation.
• China's diverse mountainous regions provide a unique study area.

Purpose:

• To analyze the distribution of mosses in relation to climatic factors in China.
• To evaluate the applicability of Canonical Correspondence Analysis (CCA) and Detrended Canonical Correspondence Analysis (DCCA) in bryoflora research.
• To investigate geographical element similarities among Chinese mountains.

Summary:

• Canonical Correspondence Analysis (CCA) and Detrended Canonical Correspondence Analysis (DCCA) were employed to analyze the relationship between 61 moss families, 23 Dicranaceae genera, 17 Campylopus species, and 35 Dicranum species with nine climatic factors across 21 mountainous regions in China.
• The study also examined geographical element similarities among nine Chinese mountains and their correlation with climatic variables.
• The findings demonstrate the effectiveness of CCA and DCCA in florological and phytogeographical studies.

Impact:

• Provides insights into the ecological factors shaping moss distribution in China.
• Highlights the utility of multivariate statistical methods in phytogeographical research.
• Contributes to a better understanding of plant-climate interactions for conservation efforts.
