Genetic Mystery: The all-female salamanders of the Great Lakes

Looking at them, you wouldn’t guess that the unisexual Ambystoma salamanders are any different than the other members of what was once considered their group.  

These interlopers were previously grouped with five other mole salamander species: the tiger salamanders with yellow stripes; the blue-spotted salamander, marked as its name suggests; the brownish smallmouth salamander and Jefferson salamander; and the pale streamside salamander.

The two men, friends since childhood, took a trip to the active quarry site and spoke with the foreman about any fossils that might have been found.

Piping Plovers: Despite new challenges, the birds make their comeback

When biologist Jillian Farkas stepped into the position of piping plover coordinator for the U.S. Fish and Wildlife Service in January 2020, there was no way she could have predicted just how unprecedented the coming season would be.

Her role involves coordinating dozens of scientists and volunteers across six states, two tribes and multiple government agencies—all to help preserve the endangered Great Lakes population of piping plovers.

Mussel-Phosphorus Puzzle: Invasive mussels are reshaping the chemistry of the Great Lakes

Since the late 1980s, four of the five Great Lakes have played host to an increasing number of invasive mussels. First came zebra mussels, followed shortly thereafter by quagga mussels, both members of the Dreissenid family whose native range includes the waters around Ukraine.

Today, the filter-feeders comprise more than 90% of the total animal biomass of the Great Lakes (barring Lake Superior, whose depth and water chemistry make it a less suitable habitat for the two species of mussel).

Dams Across the Great Lakes: End of the line for aging infrastructure?

After nearly a century of generating hydroelectric power on the St. Regis River in upstate New York, the Hogansburg Dam came down in December 2016.
