May 19, 2021 NEWPORT, Ore. – The population of white sharks that call the Central California coast their primary home is holding steady at about 300 animals and shows some signs of growth, a new long-term study of the species has shown. Between 2011 and 2018, researchers were able to identify hundreds of individual adult and subadult white sharks, which are not fully mature but are old enough to prey on marine mammals. They used that information to develop estimates of the sharks’ abundance. “The finding, a result of eight years of photographing and identifying individual sharks in t...

NationofChange How an Indigenous scientist studies global change Dr. Danielle Ignace has found a way to unify her Native American and Western science identities to better understand big ecosystem changes. All it took was one college research trip to Colorado’s Rocky Mountains for Danielle Ignace to know her intended career path in medicine was the wrong fit. After spending a month in the mountains, she quickly learned she wanted to study ecology. “I was just kind of hooked,” she told  The Revelator. “I really wanted to work on these big questions about how climate change ...

OSU study: Bird species losses on remote island in Panama point to lack of habitat connectivity Ghislain Rompré Losses top 25% as bird population is 'drying out' CORVALLIS, Ore. (KTVZ) – Free from human disturbance for a century, an inland island in Central America has nevertheless lost more than 25% of its native bird species since its creation as part of the Panama Canal’s construction, and scientists say the losses continue. The Barro Colorado Island extirpations show how forest fragmentation can reduce biodiversity when patches of remnant habitat lack connectivity, according to a st...

The Barro Colorado Island extirpations show how forest fragmentation can reduce biodiversity when patches of remnant habitat lack connectivity, according to a study by researchers at Oregon State University. Even when large remnants of forest are protected, some species still fail to survive because...
