生物可以通过适应它们表现最好的温度和/或通过分散到更有利的位置来应对气候变化下不断变化的温度。然而，一个新的热生态位在射程转移期间的进化预计将受到遗传负荷的强烈限制，因为空间排序已知会导致扩散的快速进化。为了扩大我们对这种相互作用的理解，我们应用基于个体的空间显式模型，研究了在射程移动过程中种群的分散和热性能曲线(TPC)的联合演化。总而言之，TPC适应了当地的热条件。值得注意的是，这种适应与移动范围前沿的扩散演化相吻合，变化范围前沿的扩散与后缘的扩散相同或相同。这一最优策略减少了遗传负荷，并强调了当关键性状(如散布和热性能)共同进化时，范围转移期间的进化动态发生变化。
Organisms can cope with changing temperature under climate change by either adapting to the temperature at which they perform best and/or by dispersing to more benign locations. The evolution of a new thermal niche during range shifting is, however, expected to be strongly constrained by genetic load because spatial sorting is known to induce fast evolution of dispersal. To broaden our understanding of this interaction, we studied the joint evolution of dispersal and thermal performance curves (TPCs) of a population during range shifting by applying an individual-based spatially explicit model. Always, TPCs adapted to the local thermal conditions. Remarkably, this adaptation coincided with an evolution of dispersal at the shifting range front being equally high or lower than at the trailing edge. This optimal strategy reduces genetic load and highlights that evolutionary dynamics during range shifting change when crucial traits such as dispersal and thermal performance jointly evolve.
