From spots on leopards to stripes on zebras to hexagons on boxfish, nature creates an almost infinite array of dazzling patterns and stunning colors. But a full explanation for how these designs form has remained elusive—until now.

Ever since the HMS Beagle arrived in the Galapagos Islands with a young Charles Darwin aboard—who was soon to meet a fateful family of finches—ecologists have struggled to understand a particularly perplexing question: Why is there such a ridiculous abundance of species in some places on Earth and a scarcity in others?

“This is the most magnificent mammal on our continent. Its story is so complicated and so interesting and moves into every aspect of almost every era of our lives and touches on so many subjects you wouldn’t think it would necessarily touch on,” says filmmaker Ken Burns of our national mammal, Bison bison.

On December 28, 1973, the Endangered Species Act (ESA) was signed into law. We’ll soon be celebrating the 50th anniversary of this landmark conservation legislation, which has saved hundreds of animals that once wavered on the brink of extinction.

Africa’s great wildebeest migration and Mexico’s “living mountain” of fluttering butterfly wings are just two of nature’s many amazing and fun phenomena. But, especially appropriate for this time of year, nature holds some scary wonders, as well. One of them is ants who become real-life zombies.

Cities provide us with many benefits: better educational and employment opportunities, exposure to more diversity and multicultural influences, improved infrastructure and access to public transportation. On the other hand, urbanization and the consequent changes in land use often result in air, land and water pollution; economic inequalities; an increase in health issues; and overcrowding.

Alaska’s Arctic National Wildlife Refuge—one of the world’s most breathtaking natural wonders and culturally significant areas—received some much-needed support recently. In early September 2023, President Biden canceled the last seven gas and oil leases there.

When you walk through a forest, you surround yourself with carbon. Every branch, every leaf, every tendril of unseen root and every inch of trunk contains carbon pulled from the atmosphere through photosynthesis.
