当前的生物多样性危机强调了了解生物多样性丧失如何影响现实世界生态系统中生态系统功能的必要性。在任何一个地方和时间,少数高度丰富的物种往往提供大部分功能,这表明功能可以保持相对较少的生物多样性。然而,如果需要不同物种在不同时间发挥功能,生物多样性在较长时间尺度上可能对生态系统功能至关重要。在这里,我们表明,需要保持作物授粉的阈值水平的野生蜜蜂物种的数量急剧增加的时间尺度检查:两到三倍的蜜蜂物种需要在一个生长季节相比,在一天和两倍的物种需要在六年内相比,在一年。我们的研究结果表明,授粉生物多样性的重要性,以维持跨时间授粉服务,从而稳定的农业产量。
The current biodiversity crisis underscores the need to understand how biodiversity loss affects ecosystem function in real-world ecosystems. At any one place and time, a few highly abundant species often provide the majority of function, suggesting that function could be maintained with relatively little biodiversity. However, biodiversity may be critical to ecosystem function at longer timescales if different species are needed to provide function at different times. Here we show that the number of wild bee species needed to maintain a threshold level of crop pollination increased steeply with the timescale examined: two to three times as many bee species were needed over a growing season compared to on a single day and twice as many species were needed over six years compared to during a single year. Our results demonstrate the importance of pollinator biodiversity to maintaining pollination services across time and thus to stable agricultural output.
