农业强度影响下双翅目群落生物量和丰度的复杂时间趋势
昆虫生物多样性和数量的减少已被广泛报道,预计将改变生态系统的功能和过程。土地利用的变化已被认为是造成这种下降的主要原因。然而,由于当地环境驱动因素和可用监测数据规模的差异,在哪些分类群正在减少、哪些地方减少最严重以及这些减少将如何影响生态系统等方面留下了巨大的知识空白。我们利用加拿大魁北克省南部约 10,000 平方公里范围内 40 个农场的 11 年(2006-2016 年)监测数据,量化了农业密度对双翅目(真蝇)数量和生物量的时间趋势的影响。我们发现,不同农场之间的时间趋势存在很大差异,这主要是由农业用地所造成的。与预期相反,在农业密度较高的地区,双翅目昆虫的数量随着时间的推移增加得更多,尤其是在谷类作物增加的情况下。与此相反,农业密集度较高地区的生物量下降幅度更大,不过这只是由于玉米和大豆产量增加,而非小麦等谷物产量增加。农场周围森林覆盖率的变化对趋势的影响最小。我们发现,随着农业密集覆盖率的增加,双翅目昆虫单位总数的生物量下降更快,这表明群落正在向个体生物量较低的小体型苍蝇转变。我们的研究结果表明,土地利用不仅会改变昆虫物种群的数量和物种组成,还会改变昆虫主要功能特征(如体型)的分布。
