In 1980, conservationists began eradicating feral sheep to restore California’s Santa Cruz Island; by 1987 numbers fell from 21,500 to under 100, then 12 lambs were rescued to save the breed

In 1980, conservationists began an ambitious ecological restoration programme on Santa Cruz Island, off the coast of Southern California. The main goal was to remove tens of thousands of feral sheep whose uncontrolled grazing was damaging native plants and threatening wildlife habitats. Over the next seven years, organised eradication efforts dramatically changed the island’s landscape….

Scientists found hidden populations within common gut bacteria that can spread internationally within decades and are associated with ageing, colorectal cancer, IBD and type 2 diabetes

The study, published in Nature, could also change how scientists identify links between gut bacteria and disease. The human gut is home to trillions of microorganisms that together form the gut microbiome. These microbes play important roles in digestion, immune function and metabolism. Now, researchers led by the University of Vienna have found that common…

For decades, a concrete barrier on Virginia’s Appomattox River stood between migratory fish and more than 120 miles of upstream habitat. In 2014, its removal changed that. The Harvell Dam in Petersburg was taken out as part of a collaborative restoration effort, reconnecting roughly 127 miles of river for migratory and resident fish, according to…

Representative image of DNA All life on Earth, from bacteria to blue whales, writes its genetic instructions using the same four-letter alphabet. These four DNA bases, usually referred to as A, T, C and G, pair up in predictable ways to store and pass on the information needed for life. Now, researchers at UC San…
