Overview

Analysis uncovers varied extinction rates in different clades, with habitat loss being a significant threat.

Key Points

  • Current extinction rates vary significantly among clades, and extinctions in molluscs and tetrapods are notably higher.
  • Biodiversity loss has escalated over 500 years; however, rates have declined in the last 100 years for some groups.
  • Invasive species have significantly impacted island extinctions, while habitat loss poses the greatest risk in continental regions.
  • Surprisingly, past extinctions do not strongly predict current risk across different environments and life forms.
