Science Evolves

While evolution often evokes thoughts about ancient origins of life, University of Maine researcher Michael Kinnison says applied evolutionary biology is about improving the future — including pressing matters of day-to-day life and issues of international policy.

A paper by lead authors from the University of Copenhagen and the University of California, Davis, as well as Kinnison, highlights ways in which food security, human health and biodiversity can benefit in the short- and long-term by using principles of evolutionary biology.

The paper published online Sept. 11 at Science Express indicates when evolution is overlooked the prevailing approaches to treat human disease, reduce agricultural pests and manage at-risk wildlife can be detrimental to achieving sustainable solutions and exacerbate the very problems they’re trying to prevent.

The Southern Ocean that encircles Antarctica lends a considerable hand in keeping Earth’s temperature hospitable by soaking up half of the human-made carbon in the atmosphere and a majority of the planet’s excess heat.

Yet, the inner workings — and global importance — of this ocean that accounts for 30 percent of the world’s ocean area remain relatively unknown to scientists, as dangerous seas have hindered observations.

Princeton University and 10 partner institutions seek to make the Southern Ocean better known scientifically and publicly through a $21 million program that will create a biogeochemical and physical portrait of the ocean using hundreds of robotic floats deployed around Antarctica.

Old-timers sharing childhood stories about growing up in Maine sometimes recount hiking 10 miles uphill in 3 feet of snow to get to school — and home.

Turns out those tales, of Maine winters anyway, might not be all that exaggerated.

Fantastic Migrants

Sandpiper

Saturday, Sept. 6 is World Shorebirds’ Day — a time to celebrate “fantastic migrants.” For biologists Rebecca Holberton and Lindsay Tudor, nearly every day is World Shorebirds’ Day.

They’re in the midst of a two-year study of one of those fantastic migrants — the semipalmated sandpipers (Calidris pusilla). Named for the short webs between their toes, the small sandpipers scurry synchronously on black stilt-like legs, “cherking” and searching for food on the shore.
