物种相互作用的破坏是气候变化生物学的一个关键问题。涉及林木的相互作用可能是特别脆弱的，由于进化速率的限制所施加的世代时间长。气候匹配是缓解这种影响的一种策略--通过目前正在经历预测的未来气候的非本地种群的输入来增加本地原生树木种群。这一战略是有争议的，因为对当地适应动物群落的潜在级联影响。我们探讨了这些影响，使用丰富的数据本地gallwasp食草动物采样20种源的无柄橡树（栎petraea）种植在一个共同的花园试验。我们假设，非本地种源将显示（i）下降的生长性能与种源的起源和试验地点之间的距离增加，和（ii）物候差异，以当地橡树，增加与原产地和试验地点之间的纬度差异。根据当地的适应假设，我们预测下降gallwasp丰富的增加本地和气候匹配的树木之间的物候不匹配。这两个假设橡树得到支持。种源解释显着变化的瘿蜂丰度，但没有瘿类型显示丰度和物候不匹配的本地适应假说预测之间的关系。我们的研究结果表明，气候匹配将有复杂的和可变的影响橡树瘿群落。
Disruption of species interactions is a key issue in climate change biology. Interactions involving forest trees may be particularly vulnerable due to evolutionary rate limitations imposed by long generation times. One mitigation strategy for such impacts is Climate matching – the augmentation of local native tree populations by input from nonlocal populations currently experiencing predicted future climates. This strategy is controversial because of potential cascading impacts on locally adapted animal communities. We explored these impacts using abundance data for local native gallwasp herbivores sampled from 20 provenances of sessile oak (Quercus petraea) planted in a common garden trial. We hypothesized that non-native provenances would show (i) declining growth performance with increasing distance between provenance origin and trial site, and (ii) phenological differences to local oaks that increased with latitudinal differences between origin and trial site. Under a local adaptation hypothesis, we predicted declining gallwasp abundance with increasing phenological mismatch between native and climate-matched trees. Both hypotheses for oaks were supported. Provenance explained significant variation in gallwasp abundance, but no gall type showed the relationship between abundance and phenological mismatch predicted by a local adaptation hypothesis. Our results show that climate matching would have complex and variable impacts on oak gall communities.
