温度是物种基本生态位的核心组成部分。在大多数生物所经历的气候的细微尺度上（毫米到公顷），温度取决于到达地球表面的辐射量，而辐射量主要由植被决定。热带地区的植被发生了广泛和极端的变化，特别是由于雨林的退化和转化。由于大多数陆地生物多样性都在热带地区，其中许多物种的温度限制很窄，因此必须查明雨林退化和转换对当地的热影响。我们从文献中收集了泛热带地区的站点水平（<1公顷）温度数据，以量化土地利用变化对当地温度的影响，并研究这种关系是否与地面相对于地下以及雨季和旱季不同。我们发现，在所有人类影响的土地利用类型中，我们样本点的当地温度高于原始森林（来自25项研究的N = 113，894个白天温度测量值）。在森林转变为农业用地后，变暖明显（最低+1.6 ° C，最高+13.6 ° C），但与森林退化相比，变暖幅度很小，不显著（例如，通过选择性记录;最低+1 ° C，最高+1.1 ° C）。这种影响在地下得到缓冲（最小缓冲0°C，最大缓冲11.4°C），而季节性影响最小（最大缓冲1.9°C）。我们的结论是，在热带雨林转变后持续存在的依赖森林的物种经历了显著的局部变暖。砍伐森林使这些物种更接近它们的温度极限，使得未来扰动的复合影响，如严重干旱和全球变暖，更有可能超过物种的耐受力。相比之下，退化的森林和地下生境可能为农业用地为主的景观中的热限制物种提供重要的避难所。
Temperature is a core component of a species' fundamental niche. At the fine scale over which most organisms experience climate (mm to ha), temperature depends upon the amount of radiation reaching the Earth's surface, which is principally governed by vegetation. Tropical regions have undergone widespread and extreme changes to vegetation, particularly through the degradation and conversion of rainforests. As most terrestrial biodiversity is in the tropics, and many of these species possess narrow thermal limits, it is important to identify local thermal impacts of rainforest degradation and conversion. We collected pantropical, site‐level (<1 ha) temperature data from the literature to quantify impacts of land‐use change on local temperatures, and to examine whether this relationship differed aboveground relative to belowground and between wet and dry seasons. We found that local temperature in our sample sites was higher than primary forest in all human‐impacted land‐use types (N = 113,894 daytime temperature measurements from 25 studies). Warming was pronounced following conversion of forest to agricultural land (minimum +1.6°C, maximum +13.6°C), but minimal and nonsignificant when compared to forest degradation (e.g., by selective logging; minimum +1°C, maximum +1.1°C). The effect was buffered belowground (minimum buffering 0°C, maximum buffering 11.4°C), whereas seasonality had minimal impact (maximum buffering 1.9°C). We conclude that forest‐dependent species that persist following conversion of rainforest have experienced substantial local warming. Deforestation pushes these species closer to their thermal limits, making it more likely that compounding effects of future perturbations, such as severe droughts and global warming, will exceed species' tolerances. By contrast, degraded forests and belowground habitats may provide important refugia for thermally restricted species in landscapes dominated by agricultural land.
