Invasive species, pathogens, and parasites can have serious ecological consequences for aquatic ecosystems and also put human health and economies at risk. Early detection of these biological threats ...

Antarctic scientists have trialed a DNA "barcoding" technique that could improve biosecurity measures that help protect polar ecosystems from invasive marine species. The research, led by Australian ...

Sampling for eDNA consists of collecting and analyzing water samples for the presence of DNA from the organism of interest. Of the 330 water samples collected in 2024 from the lake, six tested ...

As the SARS-CoV-2 puts a new focus on zoonotic pathogens, a Washington State University researcher has developed a method to use environmental DNA (eDNA) to detect disease in the vast international ...

Tracking environmental DNA (eDNA) is fast becoming a popular method of monitoring aquatic biodiversity, but current methods are expensive and cumbersome. Filter-feeding sponges can act as natural ...

During the annual salmon run last fall, University of Washington researchers pulled salmon DNA out of thin air and used it to estimate the number of fish that passed through the adjacent river. Aden ...

MILWAUKEE - The Wisconsin Department of Natural Resources (DNR) announced Tuesday, Oct. 5 that it would conduct targeted invasive carp sampling in the Milwaukee River with assistance from U.S. Fish ...

Some critters in the ocean are reclusive, hiding from human probes and trawls. Other critters are rare, driven close to extinction from warming and increasingly acidic waters. Studying rare and ...

University of Florida scientists have rolled out a DNA "tripwire" that can flag two notoriously stealthy invasive fish from just a few drops of canal water, giving Florida a new early-warning system ...
