Over the course of 2017, we continued to invest in bold people and transformative ideas with more than 600 grants, totaling nearly $12 million. This led to amazing discoveries AND achievements by our Explorer community. Our Explorers also led the way in helping protect life on Earth through their dedication and impact.
National Geographic Society looked at the collection of amazing accomplishments and cultivated our top highlights from this past year (in no particular order).
Troubling Trend for Cheetahs
These iconic cats are fighting for survival.
National Geographic researchers from its Big Cats Initiative say these animals should be moved up from “Vulnerable” to “Endangered” on the International Union for Conservation of Nature Red List.
In a study published in PeerJ, researchers presented evidence that low cheetah population estimates in southern Africa and population decline support a call for up-listing the species to Endangered.
Edge of Extinction
The Sumatran tiger could become extinct very soon as deforestation increases due to the rise of palm oil plantations.
National Geographic Explorer Matthew Luskin estimates 600 of these big cats remain in the wild, according to his research paper published in Nature Communications.
“The erosion of large wilderness areas pushes Sumatran tigers one step closer to extinction. We hope this serves as a wake-up call,” Luskin said.
Marine Protection Gets Support
It was a great year for marine protection. Our Pristine Seas team was proud that its science and story-telling helped support the creation of a number of new protected areas in Nieu, Chile and Mexico.
National Geographic’s Pristine Seas project, led by Explorer-in-Residence Enric Sala, shared the news of the governments’ decisions from Malta at the Our Ocean conference.
Combined, the three marine parks protect 290,000 square miles of ocean from fishing and extractive activities — an area more than twice the size of Germany.
A Beautiful Find
National Geographic Explorer Isaiah Nengo discovered an infant ape skull believed to be approximately 13 million years old.
Named “Alesi” by Nengo’s team, the early ape is so well preserved, scientists can see the young ape’s unerupted teeth and an impression of its brain.
“We’ve been looking for ape fossils for years — this is the first time we’re getting a skull that’s complete,” said Nengo, who found Alesi at the Middle Miocene site of Napudet, Kenya.
Poison Frog Mystery Revealed
A small species of poison frog covered in toxins can be lethal to other animals but immune to their own defenses.
National Geographic Explorer Rebecca Tarvin discovered a genetic mutation in Neotropical frogs keeps them safe from the toxic effects of epibatidine, a chemical that can cause hypertension, seizures, and even death in other animals.
The mutation is tiny — a change in three of the 2,500 amino acids that make up a receptor which binds to receptors in other animals.
