Overview

Observational analysis reveals significant changes in butterfly richness and turnover in tepui, suggesting conservation needs in high-altitude regions.

Key Points

  • Richness and abundance of butterfly species decrease with altitude, highlighting notable trends in biodiversity.
  • From 1000 to 1820 m, turnover decreases while endemic species increase significantly, especially above 1500 m.
  • The study involved sampling across 14 plots using traps and entomological nets over 21 days, totaling 299 individuals from 93 species.
  • Findings support the importance of conservation strategies in the Guiana Highlands, an area of high biodiversity.
