Intraspecific trait variation mediates realized extinction and unpaid extinction debt in island ecosystems.

The New phytologist - 1 Oct 2026

Zhang Aiying, Zhang Shiting, Song Yijuan, Yu Mingjian, Mao Lingfeng

Abstract excerpt

The Equilibrium Theory of Island Biogeography (ETIB) explains species diversity through colonization-extinction balance yet assumes species are functionally uniform. We extend ETIB by incorporating intraspecific trait variation (ITV) and species abundance into extinction dynamics in 66 woody plant species on 29 land-bridge islands in China's Thousand Island Lake. Using demographic censuses from 2009 to 2019 and...
