英文摘要: For tropical forest restoration to result in long-term biodiversity gains, native trees must establish self-sustaining populations in degraded sites. While many have asked how seedling recruitment varies between restoration treatments, the long-term fate of these recruits remains unknown. We address this research gap by tracking natural recruits of 27 species during the first 7 years of a tropical forest restoration experiment that included both planted and naturally regenerating plots. We used an individual-based model to estimate the probability that a seedling achieves reproductive maturity after several years of growth and survival. We found an advantage for recruits in naturally regenerating plots, with up to 40% increased probability of reproduction in this treatment, relative to planted plots. The demographic advantage of natural regeneration was highest for mid-successional species, with relatively minor differences between treatments for early-successional species. Our research demonstrates the consequences of restoration decision making across the life cycle of tropical tree species. © 2018 John Wiley & Sons Ltd/CNRS 资源类型: 期刊论文
