International scientists and Ngātiwai, a Māori tribe, teamed up to sequence the genome of a rare reptile, the tuatara, uncovering some unique aspects of the tuatara’s evolution. The genome sequence will enable comparative studies to better understand the evolution of the tuatara and its distant relatives: other reptiles, birds, and […]

Overall Winner: “Sick” by David Costantini. Viruses are a significant ecological concern because they are responsible for a variety of pathological effects in wildlife. This picture shows a chick of Magnificent frigatebird (Fregata magnificens) with clear signs of a viral disease that gives low chances of recovery. Credit: David Costantini […]

In one corner: the Bullock’s Oriole, found in the western half of North America. In […]

Global survey reveals sharks are functionally extinct on many of the world’s reefs, but hope lies in key conservation measures. Though many people find them intimidating, menacing or just plain scary, sharks are vital to the health of the world’s oceans. These often misunderstood creatures are found in just about […]

Animation In a study published recently in Ecology and Evolution, an international team of researchers focused on what can happen to ocean ecosystems when fishing pressure increases or decreases, and how this differs between tropical to temperate marine ecosystems. The team, led by Elizabeth Madin, researcher at the Hawai’i Institute of […]

Research from the University of Sheffield has revealed why some bird species take longer to develop than others Findings could help scientists predict how animals will adapt to climate breakdown and habitat destruction The study is the first to consider the importance of lifestyle, environment, evolutionary history, and body size […]

A new way of looking at marine evolution over the past 540 million years has shown that levels of biodiversity in our oceans have remained fairly constant, rather than increasing continuously over the last 200 million years, as scientists previously thought. A team led by researchers from the School of […]

An international team of evolutionary biologists and paleontologists have reconstructed the evolution […]

They soared the skies for 160 million years–much longer than any species of modern bird. Despite their aeronautic excellence, these ancient […]
