The endangered Arroyo toad is among the species that SCCWRP and its partners tracked in San Diego-area streams using the environmental DNA – or eDNA – that organisms have shed into their environment. Incorporating eDNA methods into routine stream monitoring programs has the potential to provide additional lines of evidence about overall stream health.

The carapace, or exoskeleton, of Dungeness crab larvae is vulnerable to shell dissolution as a result of ocean acidification. Above, extensive pit marks are visible on the carapace of a crab larva magnified 11,000 times. SCCWRP and its partners also have found mechanical sensory organ loss in the larvae, reshaping scientists’ understanding of how low pH waters can impact coastal biological resources.

Wastewater treatment operators like the Sanitation Districts of Los Angeles County, above, are at the center of a newly launched study examining how wastewater influent could be used to monitor the prevalence of COVID-19 infections in communities in near real time. SCCWRP is part of a national research team that is seeking to build a routine COVID-19 surveillance system using wastewater streams.
