Scientists solve long-standing ecological riddle

The fundamental mechanisms underlying global productivity-diversity patterns have been debated by ecologists for decades. Methodological advances are now permitting a glimpse at the processes that lie behind surface patterns.

Researchers have found clear evidence that communities rich in species are substantially healthier and more productive than those depleted of species, once complicating factors are removed. An international group of scientists, including University of Washington ecologist Jonathan Bakker in the School of Environmental and Forest Sciences has solved this long-standing ecological riddle using new scientific techniques for analyzing complex data to answer the question: How do we know that conserving biodiversity is actually important in the real world?

Northwest winter weather: El Niño, coastal effects, no more 'blob'

A U.S. projection for trends in precipitation (left) and temperature (right) during the first three months of 2016. Washington state is expected to be drier (brown) and warmer (red) than usual, in this Dec. 17 seasonal forecast.

What some have called the “Godzilla El Niño” is now lumbering ashore, right on schedule. El Niño tends to influence North American weather after the first of January, and indeed, we’re seeing warm temperatures in Alaska and much-needed rain in California. University of Washington researchers are tracking what the season will deliver to the Pacific Northwest region. For Washington, El Niño typically brings warm, and often dry, winter weather.

West Coast study emphasizes challenges faced by marine organisms exposed to global change

Washington’s northwest coast.

The Pacific Ocean along the West Coast serves as a model for how other areas of the ocean could respond in coming decades as the climate warms and emission of greenhouse gases like carbon dioxide increases. This region—the coastal ocean stretching from British Columbia to Mexico—provides an early warning signal of what to expect as ocean acidification continues and as low-oxygen zones expand.
