Mate-choice copying accelerates species range expansion

Mate-choice copying is a type of social learning in which females can change their mate preference after observing the choice of others. This behaviour can potentially affect population evolution and ecology, namely through increased dispersal and reduced local adaptation. Here, we simulated the effects of mate-choice copying in populations expanding across an environmental gradient to understand whether it can accelerate or retard the expansion process. Two mate-choice copying strategies were used: when females target a single individual, and when females target similar individuals. We also simulated cases where the male trait singled out by females with mate-choice maps perfectly onto their genotype or is influenced by genotype-by-environment interactions. These rules have different effects on the results. When a trait is determined by genotype alone, populations where copier females target all similar males expand faster, and the number of potential copiers increases. However, when p..., , , # **Mate-choice copying accelerates species range expansion** [https://doi.org/10.5061/dryad.bzkh189jh](https://doi.org/10.5061/dryad.bzkh189jh) This database contains the code used to run the individual-based simulations used to study the effects of mate-choice copying in a population expanding through an environmental gradient. These simulations show that different preference rules and mate-choice copying strategies can affect the speed of population range expansion. ## **Description of the data and file structure** The simulation code is contained in 5 different files: * **main.c**: This is the main file for the simulation. It contains the fixed parameters for the simulation (described in the comments of the code itself), the link to all the other files, and the main code to run each generation loop and the simulation itself. * **input.h**: This is the file with the parameters that were changed during the different simulations. The file also contains a description of each parame...配偶选择拷贝（mate-choice copying）是一类社会学习行为，指雌性个体在观察到其他个体的择偶选择后，会改变自身原有的配偶偏好。该行为可通过提升扩散能力、降低局部适应性等途径，潜在影响种群演化与生态进程。本研究针对环境梯度下的扩张种群，模拟配偶选择拷贝的效应，以探究其能否加速或延缓种群扩张过程。本研究采用两类配偶选择拷贝策略：其一为雌性仅靶向单个雄性个体，其二为雌性偏好特征相似的雄性个体。此外，本研究还模拟了两种场景：雌性通过配偶选择所锁定的雄性性状完全由其基因型决定，或是该性状受基因型-环境互作调控。这些规则对模拟结果存在差异化影响。当性状仅由基因型决定时，存在拷贝型雌性且其靶向所有相似雄性的种群扩张速度更快，潜在拷贝者的数量也会增加。然而当... # **配偶选择拷贝加速物种分布范围扩张** https://doi.org/10.5061/dryad.bzkh189jh 本数据集包含用于开展研究的基于个体的模拟（individual-based simulations）代码，该研究旨在探究环境梯度下扩张种群中配偶选择拷贝的效应。此类模拟结果显示，不同的偏好规则与配偶选择拷贝策略，会对种群分布范围的扩张速度产生影响。 ## **数据与文件结构说明** 模拟代码包含5个独立文件： * **main.c**：本模拟的主程序文件，内含模拟的固定参数（详见代码注释）、所有附属文件的调用链接，以及用于运行每一代循环与整个模拟流程的核心代码。 * **input.h**：该文件存储了不同模拟场景中调整的参数，同时对每个参数进行说明。
