The combination of genomic offset and niche modelling provides insights into climate change-driven vulnerability

Y. Chen, Z. Jiang, et al.

This study dives into the impacts of global warming on biodiversity loss, focusing on two bird species in the Sino-Himalayas. It highlights how cold-tolerant populations demonstrate unique genomic adaptations that can aid in evolutionary rescue. Conducted by Yilin Chen, Zhiyong Jiang, Ping Fan, Per G. P. Ericson, Gang Song, Xu Luo, Fumin Lei, and Yanhua Qu, this research is a crucial step towards integrating genomic insights with conservation efforts.

Abstract

Global warming is exacerbating biodiversity loss. This study incorporates intraspecific variation in genomic offset and ecological niche modelling to assess climate change vulnerability in two Sino-Himalayan bird species. Cold-tolerant populations showed higher genomic offset but less niche suitability decline. A genome-niche index identified cold-tolerant populations as potential donors for evolutionary rescue. Landscape genetic analysis evaluated rescue routes. Integrating genomic offset, niche modelling, and landscape connectivity improves vulnerability assessments and conservation management.
