Post-fire recovery in fire-sensitive tropical forests: the role of habitat loss and resilience thresholds

Fire is a major driver of ecological change in tropical forests, yet the combined effects of fire history and habitat loss on frugivorous birds and post-fire vegetation recovery remain poorly understood. We evaluated how fire severity, extent, and frequency-together with forest cover-shape frugivore abundance and influence short-term (≤ 10 years) forest resilience in the Cantareira-Mantiqueira Corridor, southeastern Brazil. Using frugivore surveys conducted at fixed points across 15 landscapes, combined with satellite-derived fire metrics and kNDVI-based estimates of engineering resilience, we applied a set of hypothesis-driven Generalized Linear Models and segmented regressions. Fire characteristics alone did…
