1. 随着人类活动的加剧,各种生态系统发生稳态转换的案例都在快速增加。 因此,了解和预测稳态转换是生态学中的关键挑战。 已有的研究主要集中在单一环境驱动因素(例如富营养化)和系统崩溃之前的预警信号(EWS)。 但是,目前尚不清楚多种环境胁迫因素如何相互作用以塑造生态行为,以及在湖泊生态系统恢复之前是否可检测到预警信号。 2. 在气候变暖,富营养化和鱼类放养的综合压力下,我们发现了武汉东湖生态系统突变和时滞的经验证据。该稳态转换在64年的多营养级水平的长期监测和古硅藻记录中得到了交叉验证。 3. 我们的研究表明,在系统崩溃和恢复之前均可以检测到预警信号,并且包含个体大小信息的复合预警指标需要更短的时间序列数据,并且可以提高稳态转换的预测能力。尽管我们尚未观察到生态系统完全恢复,预警信号为我们采...
