OSU study: After two hours, sunscreen that includes zinc oxide loses effectiveness, becomes toxic

CORVALLIS, Ore. – Sunscreen that includes zinc oxide, a common ingredient, loses much of its effectiveness and becomes toxic after two hours of exposure to ultraviolet radiation, according to a collaboration that included Oregon State University scientists.

Species losses on isolated Panamanian island show importance of habitat connectivity

CORVALLIS, Ore. – 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.

After 40 years, new fish species in OSU Ichthyology Collection named by students on Guam

CORVALLIS, Ore. – Four decades after their capture more than a half-mile below the ocean’s surface, three snailfish species have received their scientific names, two of them from school children on Guam in the island’s native Chamorro language.

Low-level thinning can help restore redwood forests without affecting stream temperatures

CORVALLIS, Ore. – Selectively cutting trees in riparian zones to aid forest restoration can be done without adversely affecting streams’ water temperature as long as the thinning isn’t too intensive, new research by Oregon State University shows.

Electrical transmission lines have power to enhance habitat connectivity for wildlife

CORVALLIS, Ore. – Converting the ground under electrical transmission towers into spaces for wildlife can enable fragmented populations to connect with one another, increasing local biodiversity and providing animals around the globe an important tool for adapting to climate change, a new study found.

Genetic markers show Pacific albacore intermingle across equator but remain separate stocks

NEWPORT, Ore. – Analyzing thousands of genetic markers in albacore tuna from the Pacific Ocean, researchers at Oregon State University have learned that just seven dozen of those markers are needed to determine which side of the equator a fish comes from.

Tweaks to land-based conservation efforts would pay huge freshwater ecosystem dividends

CORVALLIS, Ore. – Conservation projects aimed at protecting land-dwelling species could net major gains in helping species living in streams, lakes and wetlands with relatively minor adjustments, an international research collaboration that included Oregon State University has discovered.

Beavers appear to help the growth of brown trout in South America, study finds

Through field work in a remote area of Tierra del Fuego, Chile, OSU researchers determined that dam building by the beaver enables a wider range of more energy-dense food sources for brown trout.

OSU researchers part of international effort to save critically endangered seabird

The global population of the critically endangered Chinese crested tern has more than doubled thanks to a historic, decade-long collaboration among Oregon State University researchers and scientists and conservationists in China, Taiwan and Japan.

Timing key in understanding plant microbiomes

CORVALLIS, Ore. – Oregon State University researchers have made a key advance in understanding how timing impacts the way microorganisms colonize plants, a step that could provide farmers an important tool to boost agricultural production.
