Guam's brown tree snake invasion: 40-year ecological collapse confirmed

A brown tree snake, introduced to Guam via military cargo in the late 1940s, has caused the near-total disappearance of native bird species over four decades. Investigations confirm the snake's spread significantly altered the island's ecological balance, marking a classic example of invasive species impact. The finding underscores the long-term ecological vulnerability of isolated island ecosystems to accidental introductions.
