Expanding the network of connected and resilient protected areas(PAs)for climate change adaptation can help species track suitable climate conditions and safeguard *** is often overlooked when expanding PAs and quantifying their benefits,resulting in an underestimate of the benefits of expanding *** expanded PAs through terrestrial mammalian species distribution hotspots,Key Biodiversity Areas(KBAs),and wilderness ***,we constructed climate connectivity networks using a resistance-based approach and further quantified the network resilience to propose resilient climate response strategies in *** results showed that existing PAs suffered from location biases with important biodiversity *** existing PAs represented about half of the KBAs and wilderness areas,yet only 12.08%of terrestrial mammalian species distribution hotspots were located within existing *** with the existing PA network,the network efficiency and resilience of the expanded PAs'climate connectivity increased to 1.80 times and 1.78 times,*** 56%of the nodes remaining,the network efficiency of the expanded PAs was equivalent to that of the existing PAs with all *** network resilience of preferentially protecting and restoring low human footprint patches was approximately 1.5–2 times that of the random *** findings highlighted that confronted with the unoptimistic situation of global warming,nature conservation based on existing PAs was no longer *** was critical to construct a connected and resilient conservation network relying on both important biodiversity areas and low human footprint patches.
