Abstract:
Habitat fragmentation is a leading cause of plant extinctions, yet predicting which species are most vulnerable remains a key challenge. We propose that population connectivity, and thus gene flow via pollination and seed dispersal, can be inferred from plant traits. We integrate these traits into a connectivity-trait dimension, which, together with breeding system, life-history traits, and landscape context, ranks species at risk of genetic erosion and local extinction, providing an early-warning triage tool. By linking traits to gene flow mechanisms, the framework helps prioritise investment in detailed population genetic analyses and provides a scalable tool to identify species most at risk of genetic inbreeding and extinction in fragmented landscapes.

Truncation in Survival Analysis
Left truncation occurs when individuals who experienced the event of interest before a certain time are not included in the study. This is often due to a "delayed entry" into the study where only those who survive until a certain entry point are observed.
