Article Synopsis
  • Over the past 40 years, the intensity of tropical cyclones affecting coastal regions has increased, leading to concerns about their impact on forests and tree damage.
  • Researchers analyzed data from 11 cyclones and 74 forest plots to understand how factors like maximum sustained wind speed, topographical exposure, tree size, and wood density influence tree damage during these storms.
  • Their findings reveal that higher wind speeds and topographical exposure significantly increase tree damage, while denser wood and tree size play complex roles in mitigating damage, especially for smaller trees in extreme wind conditions.

Assessing how forests respond to, and recuperate from, cyclones is critical to understanding forest dynamics and planning for the impacts of climate change. Projected increases in the intensity and frequency of severe cyclones can threaten both forests and forest-dependent communities. The Pacific Islands are subject to frequent low-intensity cyclones, but there is little information on the effects of high intensity cyclones, or on how forest stewardship practices may affect outcomes.

Morphology-based studies have suggested a very depauperate bee fauna for islands in the South West Pacific, and recent genetic studies since have indicated an even smaller endemic fauna with many bee species in this region resulting from human-aided dispersal. These introduced species have the potential to both disrupt native pollinator suites as well as augment crop pollination, but for most species the timings of introduction are unknown. We examined the distribution and nesting biology of the long-tongued bee Braunsapis puangensis that was first recorded from Fiji in 2007.
