Through the work spearheaded by one family, an ecosystem reengineering experiment is bringing new life to the Arctic. It's an effort to stop the thaw of permafrost and the impending, enormous release of its greenhouse gasses.  Nearly 20,000 years ago, millions of woolly mammoths, bison, oxen, horse, and reindeer lived in the grassland steppe of northern Siberia. Today, the landscape is largely a barren tundra, a once-great grassland ecosystem ruined through hapless human activity. However, things are starting to change. In one corner of Siberia, Sergey Zimov and son...

Citizen Science for the Passenger Pigeon – Join the Project!

By Ben Novak, De-Extinction, Get Involved, Passenger Pigeon

-Ben J. Novak Revive & Restore’s Great Passenger Pigeon Comeback began in 2012 with two questions: Can we bring back the passenger pigeon to the eastern forests of the United States? And if so, why bring it back? To answer these questions, Revive & Restore with scientists from the University of California, Santa Cruz, sequenced genomes, crunched population models, reviewed historic records and forestry science, and more.  This new research significantly reshapes accepted scientific views of this iconic species. Can we bring back the Passenger Pigeon? We can’t bring the passenger pigeon back as a exact clone from a historical…

A Call for Biotechnology in Ocean Conservation

By Ocean Genomics Horizon Scan, Revive & Restore, Ryan Phelan
As 2019 comes to a close, we are likely to remember it as a remarkable year for the environment. When sixteen-year-old Greta Thunberg sailed into New York Harbor earlier this year, she produced an enormous global response. “Entire ecosystems are collapsing,” she said in an address to the United Nations General Assembly, “And all you can talk about is money and fairy tales of eternal economic growth.” While Thunberg’s message was dire, it’s hard to say it was overstated. According to the U.N. report that was released during the assembly, the immediate threats that climate change presents, especially to our...

Experimental Investigation of the Dietary Ecology of the Extinct Passenger Pigeon, Ectopistes migratorius

By Passenger Pigeon, Revive & Restore

The passenger pigeon (Ectopistes migratorius) was the dominant species in eastern North American forests for tens of thousands of years prior to its extinction in 1914. The birds lived in megaflocks comprising up to several billion individuals, moving nomadically as they consumed fruit and mast, the seed of beech, oak, chestnut, and other forest trees. The size and density of passenger pigeon flocks as well as their migratory patterns and their diet shaped the abundance and the distribution of tree species in these forests. In fact, the passenger pigeon was an ecosystem engineer of eastern North American forests for tens…
