摘要

作为生态脆弱地区,沿海地区受到人为活动和气候变化的双重影响。然而,这些因素对大型近海哺乳动物的影响,如印度-太平洋座头鲸(IPHDs,Sousa chinensis),却知之甚少。在此,模型显示,IPHDs的适宜栖息地主要受海面温度(SST)的影响,并且随着与最近海岸线距离的增加,栖息地的适宜性降低。此外,涉及底层捕捞、污染和航运的人为活动缩小了IPHD的栖息地,降低了栖息地的适宜性。我们发现,在代表性集中路径(RCP)8.5情景下,到2090–2100年,气候变化将进一步缩小距离海岸线7公里以上的适宜栖息地,并引发台湾海峡东部的栖息地丧失。栖息地适宜性和面积的预计下降强调了建立互联海洋保护区的紧迫性,同时考虑到气候变化、政府间合作和公众参与。

Anthropogenic footprints are invading global habitats of Indo-Pacific humpback dolphins

As ecologically fragile areas, coastal zones are affected by both anthropogenic activities and climate change. However, the impacts of these factors on large nearshore mammals, such as Indo-Pacific humpback dolphins (IPHDs, Sousa chinensis), are poorly understood. Here, modeling revealed that the suitable habitats of IPHDs are affected mainly by the sea surface temperature (SST), and the habitat suitability decreases as the distance to the nearest coastline increases. In addition, anthropogenic activities involving demersal fishing, contamination and shipping have narrowed IPHD habitats and reduced the habitat suitability. We found that climate change will further narrow suitable habitats located farther than 7 km from coastlines and trigger habitat losses in the eastern Taiwan Strait by 2090–2100 under the Representative Concentration Pathway (RCP) 8.5 scenario. The projected decreases in habitat suitability and area emphasize the urgency of establishing connected marine protected areas (MPAs) while considering climate change, intergovernmental cooperation, and public involvement.

期刊介绍: Geography and Sustainability serves as a central hub for interdisciplinary research and education aimed at promoting sustainable development from an integrated geography perspective. By bridging natural and human sciences, the journal fosters broader analysis and innovative thinking on global and regional sustainability issues. Geography and Sustainability welcomes original, high-quality research articles, review articles, short communications, technical comments, perspective articles and editorials on the following themes: Geographical Processes: Interactions with and between water, soil, atmosphere and the biosphere and their spatio-temporal variations; Human-Environmental Systems: Interactions between humans and the environment, resilience of socio-ecological systems and vulnerability; Ecosystem Services and Human Wellbeing: Ecosystem structure, processes, services and their linkages with human wellbeing; Sustainable Development: Theory, practice and critical challenges in sustainable development.
