New NAU study finds evolutionary processes work at multiple levels to shape whole communities

Posted by Heather Tate on November 19, 2020

LandscapeEvolutionary theory has long held that natural selection largely operates at the level of individuals. Findings from Northern Arizona University researchers, recently published in the Annual Review of Ecology, Evolution, and Systematics, suggest that selection can also occur at multiple levels to shape whole communities. This multi-level selection arises from the interactions of key species that cascade to alter communities and ecosystems.

For example, unraveling the evolution of complex forest communities that… Read more

NAU global change ecologist leads NASA satellite study of rapid greening across Arctic tundra

Posted by Heather Tate on September 22, 2020

Berner Arctic Greening illustrationAs Arctic summers warm, Earth’s northern landscapes are changing. Using satellite images to track global tundra ecosystems over decades, a team of researchers finds the region has become greener as warmer air and soil temperatures lead to increased plant growth.

“The Arctic tundra is one of the coldest biomes on Earth, and it’s also one of the most rapidly warming,” said Logan Berner, assistant research professor with Northern Arizona University’s… Read more

NAU researchers win $1.3M in NSF grants to study major shifts in carbon storage

Posted by Heather Tate on September 21, 2020

Xanthe Walker in forestTwo researchers at the Center for Ecosystem Science and Society have won separate awards totaling $1.3M from the National Science Foundation to better understand where carbon is being stored and released in the terrestrial biosphere. Using different approaches, the two projects aim to better predict carbon storage by plants and soils in critical regions of the globe, and how that storage is being altered by changing climate patterns.… Read more

NAU scientist collaborates on major genetic study of white-nose syndrome in bats

Posted by Heather Tate on October 31, 2019

Jeff Foster in the PMI lab holding a bat Often maligned and largely misunderstood throughout history, bats have more recently been recognized for the important role they play in ecosystems all over the world, pollinating flowers, dispersing seeds and controlling pests by eating insects.

But many North American species are now threatened by white-nose syndrome (WNS), a deadly fungal disease affecting millions of bats, primarily in the eastern US. The Ecology and… Read more

The frozen world and oceans at risk, says new UN special report co-authored by NAU researchers

Posted by Heather Tate on September 26, 2019

Sept. 25, 2019

The world’s oceans are getting hotter and acidifying under climate change at unprecedented rates, threatening coastal and high-mountain communities, marine ecosystems and global fishing stocks, according to a new Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC) released this week by the United Nations Intergovernmental Panel on Climate Change. Ted Schuur, a researcher in the Center for Ecosystem Science and Society (Ecoss) at Northern Arizona University, was one of the lead authors on the… Read more
