Collecting dragonfly larvae for the Dragonfly Mercury Project
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

Dragonfly (Aeshnidae) larvae
Dragonfly larvae are ideal mercury biosentinels and can be used to predict concentrations in co-located fish species.

Researchers collecting data for SageSTEP
The Sagebrush Steppe Treatment Evaluation Project (SageSTEP) is an integrated, long-term study that spans six western states. Researchers are evaluating the effects of treatments to reduce juniper and pinyon woodlands to restore sagebrush steppe communities in the Intermountain West.

Salmon carcass on gravel bar on Kodiak Island, AK
Kodiak NWR Migrating species of Pacific Salmon return to many of the rivers on Kodiak Island. After spawning, their bodies often wash up on gravel bars, providing an easy dinner for scavengers.
