Using the 384-well plate format, a single zebrafish embryo is tested in each well. This is an example of a 72 hour post fertilization fli1:egfp zebrafish (3 millimeters long) imaged under a fluorescein isothiocyanate (FITC) filter.

A USGS scientist prepares a sample to test the effect of antibiotics on denitrifying bacteria within a glove box. A glove box allows scientists to work with samples in an anaerobic (no oxygen) atmosphere, the conditions under which denitrification occurs.

Between 2009 and 2018, scientists conducted a national scale assessment of mercury accumulation in the National Park System using dragonfly larvae as biosentinels (species that accumulate a pollutant in their tissues as an index of exposure to other organisms without significant adverse effects to the biosentinel) through a citizen science network called the Dragonf

After 100 years of restricted tidal activity to support agricultural use and salt harvesting, the tidal marshes around San Francisco Bay, like this one at Bair Island, are steadily rebuilding, returning to a stunning mosaic of marsh, mudflat, and channels.
