A Watershed Moment

_An Index for the Delaware

_Stefanie Kroll

One way to assess impacts to an ecosystem and express it to the public is to compile biological indicators, like fish and algae, into an index called the Index of Biotic Integrity (IBI).

_Still-Water Dwellers

_Meghan O’Donnell

The old proverb says that “still waters run deep,” but Academy scientist Meghan O’Donnell is going one step further and asking “run deep with what?”

_Scanning Streams, Remotely

_Alex Waldman

How do Academy scientists know where to observe water quality or test sediment conditions throughout the Delaware River Basin? By “hiking” the streams using any laptop.

_Sediment and Small Habitats

_David Keller

Sediment by erosion or runoff from farm fields can cause a “domino effect” on the ecosystem, according to David Keller, project coordinator within the Fisheries Department at the Academy.

_Invasion of the Knotweed

_Kathryn Christopher

Japanese knotweed (Fallopia japonica), a non-native invasive species, has been covering a lot of ground, and water, and wreaking havoc on its environment.

_Canaries of the Stream

_David Keller

Many salamanders need water to breathe through their moist skin, so salamanders typically found by water can serve as indicators of water quality.
