在地中海，海洋物种与人类活动之间的相互作用非常普遍。宽吻海豚（Tursiops truncatus）的沿海分布，以及它们对渔业资源造成的捕食压力，导致了它们与渔业的定期互动。尽管需要大量的数据来拟合，但多物种占用模型是估计两个（或更多）物种之间共发生的相关框架，同时考虑了假阴性和潜在的种间依赖性。在此，我们扩展了多物种占用模型，整合多个数据集，结合大空间尺度的航空调查和船舶调查数据，绘制了法国地中海狮子湾拖网渔船和宽吻海豚的空间共发生图。综合多物种占用模型比单数据集多物种占用模型产生更精确的估计。我们的研究结果支持综合和多物种框架与我们的案例研究中的物种分布和理解物种相互作用相关。此外，我们将多物种占用模型应用于宽吻海豚和拖网渔船，从而绘制出共同发生的概率，这为理解大空间尺度上人类活动与海洋哺乳动物之间的相互作用开辟了有希望的途径。
In the Mediterranean Sea, interactions between marine species and human activities are prevalent. The coastal distribution of bottlenose dolphins Tursiops truncatus and the predation pressure they put on fishing stocks lead to regular interactions with fisheries. Multispecies occupancy models are a relevant framework to estimate co‐occurrence between two (or more) species while accounting for false negatives and potential interspecific dependance although requiring substantial quantity of data to fit. Here, we extended multispecies occupancy model to integrate multiple datasets to map spatial co‐occurrence between trawlers and bottlenose dolphins in the Gulf of Lion, French Mediterranean Sea combining data from aerial surveys and boat surveys at a large spatial scale. The integrated multispecies occupancy model produced more precise estimate than single‐dataset multispecies occupancy models. Our results support that both integrated and multispecies frameworks are relevant to map distribution and understand species interactions in our case study. Besides, our application of multispecies occupancy models to bottlenose dolphins and fishing trawlers enabled to map co‐occurrence probability, which open promising avenues in the understanding of interactions between human activities and marine mammals that occur at large spatial scales.
