Data from: Global tracking of marine megafauna space use reveals how to achieve conservation targets

The recent Kunming-Montreal Global Biodiversity Framework (GBF) sets
ambitious goals, but no clear pathway for how the zero loss of important
biodiversity areas and halting human-induced extinction of threatened
species will be achieved. We assembled a multi-taxa tracking dataset (11
million geopositions from 15,845 tracked individuals across 121 species)
to provide a global assessment of space use of highly mobile marine
megafauna, showing that 63% of the area they cover is used 80% of the time
as important migratory corridors or residence areas. The GBF 30% threshold
(Target 3) will be insufficient for marine megafauna’s effective
conservation, leaving important areas exposed to major anthropogenic
threats. Coupling area protection with mitigation strategies (e.g.,
fishing regulation, wildlife-traffic separation) will be essential to
reaching international goals and conserving biodiversity.

新近发布的《昆明-蒙特利尔全球生物多样性框架》（Global Biodiversity Framework, GBF）设定了宏伟的生物多样性保护目标，但并未明确如何实现"重要生物多样性区域零损失"以及"终止人类活动引发的受威胁物种灭绝"的具体路径。本研究整合了一套多类群追踪数据集——涵盖121个物种的15845个被追踪个体的1100万个地理定位点，用于对高度洄游海洋巨型动物的空间利用模式开展全球评估。分析结果显示，该类群活动范围内63%的区域在80%的时间里均作为重要洄游通道或栖息区域被持续利用。该框架提出的30%保护阈值（目标3）不足以支撑海洋巨型动物的有效保护，会使其关键区域暴露于重大人为威胁之下。将区域保护与减缓策略（例如渔业监管、野生动物与航运分流）相结合，是实现国际生物多样性目标、保护生物多样性的必要举措。
