海洋环境中的垃圾,特别是塑料垃圾,对海洋巨型动物构成了重大威胁。众所周知,鲸目动物会吞食或被海洋垃圾缠住,可能会影响到个体和种群。东南亚是生物多样性的热点地区,拥有多样化的鲸类动物群落。然而,由于缺乏调查该地区广阔海岸线的专家,有关该地区垃圾影响的关键知识差距仍然存在。这项研究旨在通过利用社交媒体,收集2009年至2019年东南亚地区与鲸类搁浅和垃圾有关的脸书帖子的数据,来解决这些差距。结果表明,至少有15种鲸类动物受到垃圾的负面影响,其中最常见的是对深潜物种的摄入。上层和中层觅食者最容易被缠结。菲律宾的达沃被确定为与垃圾有关的搁浅热点。伊洛瓦底海豚(Orcaella brevirostris)和侏儒抹香鲸(Kogia breviceps)特别容易生下垃圾。社交媒体和同行评议文献的结合可以帮助更全面地了解海洋垃圾的空间分布及其对鲸类种群的影响程度。在这项研究中,我们提供了一个有价值的在线工具的详细信息,以帮助了解海洋垃圾对鲸目动物和其他有魅力的物种的影响,这些物种是社区参与的焦点。
Litter in the marine environment, in particular plastic, is a significant threat to marine megafauna. Cetaceans are known to ingest or become entangled in marine debris, likely impacting individuals and populations. Southeast Asia is a biodiversity hotspot and harbours a diverse cetacean assemblage. However, there are key knowledge gaps relating to the impact of litter in this region due the lack of experts to survey its vast coastlines. This study aims to address such gaps by using social media, gathering data from Facebook posts relating to cetacean strandings and litter across Southeast Asia between 2009 and 2019. Results show that at least 15 cetacean species have been negatively affected by litter, with ingestion most commonly affecting deep-diving species. Epipelagic and mesopelagic foragers were most vulnerable to entanglement. Davao in the Philippines was identified as a litter-related stranding hotspot. The Irrawaddy dolphin (Orcaella brevirostris) and pygmy sperm whale (Kogia breviceps) are particularly vulnerable to litter. The combination of social media and peer reviewed literature can help build a more complete picture of the spatial distribution of marine litter and the scale of the impact it has on cetacean populations. In this study we provide details of a valuable online tool for helping to understand the impact of marine litter on cetaceans and other charismatic species that are a focus of community engagement.
