| 英文摘要 | As a result of current climate change, flooding events are becoming more frequent and lasting longer, resulting in temporal floods in areas that have not historically experienced this disturbance. One critical aspect of forest dynamics that could be significantly impacted by increasing flooding is tree species recruitment. While adult trees may be able to survive temporary flooding, establishing seedlings with shallow root systems may not. A single flooding event could jeopardize decades of recruitment if seedlings are unable to survive the anaerobic conditions imposed by higher water levels. Despite the potential impact of flooding on forest dynamics, there is little information on seedling recruitment patterns after exposure to flooding. To understand how flooding conditions could possibly be impacting forest recruitment, we conducted a field observational study across seven temperate forests. We gathered data on seedling abundance and diversity in areas with signs of recent flooding, as well as in nearby control (dry) areas. After controlling for the proximity of seed sources, our findings revealed a significant disparity between control and flooded plots in terms of seedling numbers and diversity, with control plots consistently exhibiting higher seedling abundance and species diversity. Decreases in seedling abundance ranged from 66% to 88%. This trend was consistent across most forests, except one with a historical prevalence of flooding. Species diversity was higher in control plots, with one or two species more. When comparing between native and invasive species, native seedlings tended to be more abundant in dry versus flooded plots, while invasive seedlings exhibited similar abundance under both conditions. These results point to the potential adverse effects novel flooding conditions could have on temperate forest recruitment dynamics and thus on future forest structure and composition, information that could be included in vegetation models of future forest performance as well as accounted for in the development of conservation and management plans. |
