Abstract

The geographic mosaic of coevolution predicts reciprocal selection, the first step in coevolution, to vary with changing biotic and abiotic environmental conditions. Studying how temperature affects reciprocal selection is essential to connect effects of global warming on the microevolutionary patterns of coevolution to the ecological processes underlying them. In this study, we investigated whether temperature influenced reciprocal selection between a plant (Brassica rapa) and its pollinating butterfly herbivore (Pieris rapae). In two temperature environments (ambient and hot), we measured the phenotypes of plants and butterflies, their interactions and fitness, which we used to calculate reciprocal selection. We found a variety of traits involved in reciprocal selection in the ambient environment, but none in the hot environment. We provide experimental evidence that elevated temperature weakens reciprocal selection, which will help better predict the consequences of global warming for coevolution.

高温降低了植物-传粉者-草食动物实验系统中的互惠选择

共同进化的地理马赛克预示着相互选择，共同进化的第一步，随着生物和非生物环境条件的变化而变化。研究温度如何影响相互选择，对于将全球变暖对共同进化的微进化模式的影响与潜在的生态过程联系起来至关重要。在这项研究中，我们研究了温度是否影响植物（芸苔）和它的传粉食草蝴蝶（Pieris rapae）之间的互惠选择。在两种温度环境下（常温和高温），我们测量了植物和蝴蝶的表型，它们的相互作用和适合度，我们用它们来计算互惠选择。我们发现在自然环境中有多种性状参与相互选择，但在炎热环境中没有。我们提供的实验证据表明，温度升高削弱了相互选择，这将有助于更好地预测全球变暖对共同进化的影响。

期刊介绍： Ecology Letters serves as a platform for the rapid publication of innovative research in ecology. It considers manuscripts across all taxa, biomes, and geographic regions, prioritizing papers that investigate clearly stated hypotheses. The journal publishes concise papers of high originality and general interest, contributing to new developments in ecology. Purely descriptive papers and those that only confirm or extend previous results are discouraged.
