Ecological Stressors: It's a Lot of 'WERC'
"There's is no place like California" by A. Keith Miles, Center Director, USGS Western Ecological Research Center

Highlights of the science of the USGS Western Ecological Research Center: 

The USGS field tested the use of a portable hand-held kit for the detection of the environmental DNA (eDNA) of Asian carps (bighead carp and silver carp) in water samples as part of on-going invasive species detection research. The goals of the USGS-led research are to develop a method and kit that can be used on-site to detect Asian carp eDNA within one hour.

Interviews with staff at Point Reyes National Seashore tell how this National Park Service unit uses USGS science to educate visitors, and manage the park.
 

Watch as the USGS Hammond Bay Biological Station water tank and pump house are constructed from the ground up! This short video features time lapse photography of the 1-million gallon water tank and pump house constructed to supply water to a state-of-the-art aquatic science laboratory.

This ridiculously cute video of baby Harlequin Ducks (Histrionicus histrionicus) shows their first day outside the egg (about 20 hours old). Scientists at Patuxent Wildlife Research Center are training ducks to respond to sounds — just like a hearing test given to kids during elementary school — to learn more about their ability to hear underwater.

Cell phone video of USGS biologist Diego Johnson releasing a golden eagle that had just been fitted with a tracking device.  The work is informing land managers on eagle movements in the southwest, an area of expanding renewable energy development.

Tarantula hawk wasps sting and paralyze tarantulas to feed their young. USGS Ecologist Todd Esque captured this video of a tarantula hawk wasp dragging a tarantula through the desert in Mexico.

Golden eagles can be killed by colliding with a number of human-made objects, including wind turbines. USGS research wildlife biologist Todd Katzner describes his studies of golden eagle flight. This research is being done to model flight behavior which might help managers understand how placement of wind turbines might pose significant risks to golden eagles.
