American Samoa’s coral reefs are some of the most pristine reefs in the United States. They host more than a thousand species of marine life, including some of the oldest and largest shallow-water corals on the planet. But even these remote reefs in the South Pacific Ocean face potential threats. NOAA/NCCOS evaluated the CLAM as […]

The Ministry of the Environment of Denmark has published: HITLIST – Holistic non-targeted approach to determine pesticide and biocide residues in the aquatic environment Recent technological developments in novel analytical high-resolution mass spectrometry equipment and advanced data processing tools have made a ‘non-targeted analysis’ concept feasible to find known and unknown environmental pollutants. A momentous […]

Breakthroughs in environmental DNA (eDNA) and biomonitoring help the hunt for the Loch Ness Monster. Passive Sampling and eDNA A team of researchers Led by Neil Gemmel, a university of Otago geneticist, are using environmental DNA sampling, or eDNA, to locate Nessie’s genetic fingerprint.  What is eDNA?  eDNA is the compilation of all the little […]

eDNA stands for environmental DNA and the sampling is a great method for detecting aquatic organisms such as amphibians and fish. Aquatic animals and organisms produce genetic material in water in various ways such as feces, exogenous processes or sloughed cells. The collection and analysis of eDNA from aquatic environments is a highly effective way […]
