This study shows that active restoration of logged tropical forests in Borneo leads to persistent declines in forest-dependent bird species compared to naturally regenerating forests.

Across 109,626 wood density records from 16,829 plant species (GWDD v.2), intraspecific variation explains 15% of global variance, tracks interspecific environmental gradients at 20-30% magnitude, and limits single-plant predictability.

Across 1281 bird assemblages and 3696 species, land-use change lowers functional redundancy and resistance to simulated extinctions despite lower vulnerability, hitting frugivores and invertivores hardest.

The paper creates a high-resolution global map of wood density using species and vegetation data, showing improved accuracy and a wider density range than previous estimates.

The study examines how individual species respond to tropical forest degradation, finding significant variation in responses across populations and surveys.
