We still lack a consensus on the main variables driving changes in migratory strategies. Different hypotheses have been proposed: productivity, energy, environmental heterogeneity, and genetic predisposition. This work takes an integrative view and analyses migrations from a macroecological perspective estimating the extent to which different environmental variables and historic factors influence migratory life histories.

鱼类迁移的宏观生态

我们仍然对推动迁移策略变化的主要变量缺乏共识。已经提出了不同的假设：生产力，能源，环境异质性和遗传易感性。这项工作采取了综合的观点，并从宏观生态学的角度分析了迁徙，从而估计了不同环境变量和历史因素在多大程度上影响了迁徙生活的历史。
