气候变化与高强度土地利用等其他环境压力相结合，正在日益改变生态群落的构成。压力预计会相互作用产生影响，但人类土地集约利用在多大程度上限制了社区对气候变化的反应，目前尚不清楚。气候变化影响的通用指标——群落温度指数（CTI），此前曾被用来表明鸟类和蝴蝶都成功地“跟踪”了气候变化。在这里，我们评估了三十年来英国 600 多个鸟类或蝴蝶监测点的群落变化，并测试了周围土地如何影响这些变化。我们将群落变化划分为与温暖和寒冷相关的组合，发现英国鸟类群落尚未成功地重组以应对气候变化。鸟类的 CTI 增加主要归因于与寒冷相关的物种的消失，而对于蝴蝶来说，与温暖相关的物种则趋于增加。重要的是，监测点周围集约管理的土地利用区域似乎会影响这些社区变化，大范围的集约管理土地限制了针对气候变化的“适应性”社区重组。具体来说，高强度的土地利用似乎加剧了适应寒冷的鸟类和蝴蝶物种的减少，并阻止了与温暖相关的鸟类的增加。这对于管理景观以促进气候变化适应具有广泛的影响。这项研究调查了鸟类和蝴蝶群落在气候变暖的三十年中如何变化。我们提出了第一个证据，表明社区变化似乎受到高强度土地利用的限制。这对于管理景观以促进气候变化适应具有广泛的影响。
Climate change is increasingly altering the composition of ecological communities, in combination with other environmental pressures such as high‐intensity land use. Pressures are expected to interact in their effects, but the extent to which intensive human land use constrains community responses to climate change is currently unclear. A generic indicator of climate change impact, the community temperature index (CTI), has previously been used to suggest that both bird and butterflies are successfully ‘tracking’ climate change. Here, we assessed community changes at over 600 English bird or butterfly monitoring sites over three decades and tested how the surrounding land has influenced these changes. We partitioned community changes into warm‐ and cold‐associated assemblages and found that English bird communities have not reorganized successfully in response to climate change. CTI increases for birds are primarily attributable to the loss of cold‐associated species, whilst for butterflies, warm‐associated species have tended to increase. Importantly, the area of intensively managed land use around monitoring sites appears to influence these community changes, with large extents of intensively managed land limiting ‘adaptive’ community reorganization in response to climate change. Specifically, high‐intensity land use appears to exacerbate declines in cold‐adapted bird and butterfly species, and prevent increases in warm‐associated birds. This has broad implications for managing landscapes to promote climate change adaptation. This study investigates how bird and butterfly communities have changed during three decades of climate warming. We present the first evidence to show that community changes appear to be constrained by high‐intensity land use. This has broad implications for managing landscapes to promote climate change adaptation.
