NO RATS, NO PROBLEM

Tuesday, April 18, 2023

In today’s newsletter, we travel to Australia’s rodent-free volcanic island, investigate South Africa’s lion bone trade ... and discover how poison ivy gets more toxic. Plus, scroll down to play ‘Where in the World?’

Lord Howe Island

Native wildlife and plants are thriving again on a subtropical volcanic island that is the largest of its kind to have been successfully cleared of the second most destructive being, after humans.

The island has no rats.

How did Australia’s Lord Howe Island do it? Can other populated islands do so? How dramatically has life changed?

A new day: Rats held sway on the island for more than a century. After their eradication, migratory seabirds that breed there are bouncing back. Among them: the black-winged petrel (above), photographed by Nat Geo Explorer Justin Gilligan. Read more.

IN THE SPOTLIGHT

Lion bones hang to dry

Lion bone trade: South Africa ended the trade of lion bones in 2019, but leaked customs data combined with Nat Geo on-the-ground reporting reveals networks of people that orchestrated the trade—including bone sellers, middlemen, and buyers. These findings support the idea that legal trade has provided cover for criminal syndicates smuggling lion bones across the globe as part of the multibillion-dollar illegal wildlife trade industry, Nat Geo reports. (Above, lion bones hang to dry.)

Leaves of three, let it be: As carbon dioxide levels continue to rise, poison ivy (shown above) is growing more vigorously—and becoming more toxic. Via a six-year study, the plant is able to convert the higher carbon into leaves and stems: “That was the largest response of any species in the forest,” Nat Geo reports.
