Miller E, Yamahara K, French C, Spingarn N, Birch J, Van Houtan K
Sci Data . 2022 Dec; 9(1):780. PMID: 36566263
Microplastics have been extensively documented in marine ecosystems and food webs with devastating impacts. To solve this global crisis, identifying the polymer composition is key for resolving the material origin,...

Graham K, Loeb S, Wolfe M, Catoe D, Sinnott-Armstrong N, Kim S, et al.
Environ Sci Technol . 2020 Dec; 55(1):488-498. PMID: 33283515
Wastewater-based epidemiology may be useful for informing public health response to viral diseases like COVID-19 caused by SARS-CoV-2. We quantified SARS-CoV-2 RNA in wastewater influent and primary settled solids in...

Andruszkiewicz E, Yamahara K, Closek C, Boehm A
PLoS One . 2020 Dec; 15(12):e0242689. PMID: 33264323
Monitoring aquatic species by identification of environmental DNA (eDNA) is becoming more common. To obtain quantitative eDNA datasets for individual species, organism-specific quantitative PCR (qPCR) assays are required. Here, we...

Sepulveda A, Birch J, Barnhart E, Merkes C, Yamahara K, Marin 3rd R, et al.
Sci Rep . 2020 Sep; 10(1):14389. PMID: 32873867
Autonomous water sampling technologies may help to overcome the human resource challenges of monitoring biological threats to rivers over long time periods and across large geographic areas. The Monterey Bay...

Yamahara K, Keymer D, Layton B, Walters S, Thompson R, Rosener M, et al.
PLoS One . 2020 May; 15(4):e0232054. PMID: 32352994
Microbial source tracking and a mass balance approach were used to identify sources of fecal indicator bacteria (FIB) in the Hanalei River, Kaua'i, Hawai'i. Historically, concentrations enterococci and Clostridium perfringens...

Weiskerger C, Brandao J, Ahmed W, Aslan A, Avolio L, Badgley B, et al.
Water Res . 2019 Jul; 162:456-470. PMID: 31301475
Although infectious disease risk from recreational exposure to waterborne pathogens has been an active area of research for decades, beach sand is a relatively unexplored habitat for the persistence of...

Sassoubre L, Yamahara K, Gardner L, Block B, Boehm A
Environ Sci Technol . 2016 Sep; 50(19):10456-10464. PMID: 27580258
Analysis of environmental DNA (eDNA) to identify macroorganisms and biodiversity has the potential to significantly augment spatial and temporal biological monitoring in aquatic ecosystems. Current monitoring methods relying on the...

Wang D, Yamahara K, Cao Y, Boehm A
Environ Sci Technol . 2016 Feb; 50(7):3399-408. PMID: 26903207
We evaluated the ability of chip-based digital PCR (dPCR) to quantify enterococci, the fecal indicator recommended by the United States Environmental Protection Agency (USEPA) for water-quality monitoring. dPCR uses Poisson...

Port J, ODonnell J, Romero-Maraccini O, Leary P, Litvin S, Nickols K, et al.
Mol Ecol . 2015 Nov; 25(2):527-41. PMID: 26586544
Preserving biodiversity is a global challenge requiring data on species' distribution and abundance over large geographic and temporal scales. However, traditional methods to survey mobile species' distribution and abundance in...

Sassoubre L, Yamahara K, Boehm A
Appl Environ Microbiol . 2015 Jan; 81(6):2107-16. PMID: 25576619
Billions of gallons of untreated wastewater enter the coastal ocean each year. Once sewage microorganisms are in the marine environment, they are exposed to environmental stressors, such as sunlight and...
