To be fair, he was slightly better positioned to do so, being a professor of biological sciences with the University of Nebraska. His overall expertise on the biological diversity of his adopted state led him inevitably to an appreciation not only of the Whooping Crane , but also the more common, smaller, but no less fascinating Sandhill Crane. As the subtitle implies, this appreciation drives the bulk of A Chorus of Cranes: The Cranes of North America and the World.

Canary in the Cornfield: Why the Fuss about Monarchs?

Nature Conservancy - Science

Monarch butterflies have a special place in the North American imagination. There are two large North American populations of monarch butterflies. Exposure to colder than usual temperature in the fall causes monarchs that were headed south to turn around and fly north (Guerra 2013, Kyriacou 2013). That’s right: if they hit colder temperatures, they might fly north for the winter! As mentioned above, there are two major populations of monarchs in North America.

A new paper in the journal Biology Letters uses the latest genomic techniques to give a clearer picture of canid taxonomy and hybrid origins.
