Moss community dynamics and canopy-mediated environmental influences during primary succession in a glacier retreat zone

This dataset contains field and experimental data on moss community dynamics, biomass, cover, and physiological functions (photosynthesis and N₂-fixation) along a 129-year primary successional chronosequence on the glacial retreat area of Hailuogou Glacier, eastern Qinghai-Tibet Plateau. The dataset integrates:

Successional surveys of moss biomass and cover across stages S0 to S6;

Reciprocal moss transplantation experiments among three representative successional sites with varying canopy cover;

Canopy tree litter addition experiments, testing effects of different litter types on moss function;

Functional trait measurements, including photosynthetic rates and nitrogen fixation (via acetylene reduction assay), across treatments and years (2018–2019);

Statistical analyses such as linear regression and redundancy analysis (RDA), linking environmental drivers (e.g., canopy cover, litter, throughfall NH₄⁺, daylight) to moss functional responses;

This dataset supports a study of moss community structure, biomass, cover, nitrogen fixation, and photosynthesis along a 129-year primary successional chronosequence in the Hailuogou Glacier foreland, eastern Qinghai-Tibet Plateau. The data were collected through long-term field surveys and manipulative experiments, including reciprocal moss transplantation and canopy litter addition. These data provide insights into how moss functions respond to environmental changes mediated by canopy development during succession after glacial retreat.
