Thousands of new species described in first detailed study of Earth’s vital plankton | National Monitor

… new to science. In the minds of many people plankton are “what whales eat”. However, the microscopic organisms that drift in the top layers of the worlds oceans represent one of our most crucial ecosystems. Together, the species referred to as plankton make up 90% of the mass of all ocean creatures. They represent Earth’s largest carbon sink, produce half of our Oxygen, provide the food base that all ocean ecosystems depend upon and even have an influence on the weather. “We have the …

On the edge of extinction: Tiny pupfish go without breathing to survive their harsh environment

By Stacy Brooks | April 1, 2015 And you thought you could hold your breath for a long time. Enter the desert pupfish, a tiny fish that has been playing evolutionary catch-up due to the extreme changes in its environment over the last 10,000 years. The shrinking scope of its natural habitat has caused the pupfish to adapt in a surprising way—it essentially goes without Oxygen for up to five hour stretches. Researchers Frank van Breukelen and Stanley D. Hillyard from the University of Nevada, …

World Wildlife Day: Why We Need Wild Animals | Paul Rosolie

By Paul Rosolie, Naturalist, explorer, and author of Mother to God: An Extraordinary Journey into the Uncharted Tributaries of the Western Amazon Without plants and animals, our lives would not be possible. Oxygen, clean water and soil, and our earliest tools, food, and clothing came from flora and fauna. Even our fossil fuels are the result of Paleozoic Era ecosystems that captured the sun’s energy-the same energy that we are now using billions of years later. Yet increasingly, we fail …

Low Oxygen Hobbled Recovery from History’s Worst Extinction

SAN FRANCISCO — Wild temperature swings and low Oxygen conditions may have caused life on Earth to recover in fits and starts from the planet’s worst extinction, new research suggests. After the end-Permian extinction, in which most life on Earth perished, life rebounded only to be blasted again by hostile environmental conditions. “It was a series of rebounds and resets,” said study co-author Carlie Pietsch, a doctoral candidate in earth sciences at the University of …
