Researchers in England devised a new method for monitoring biodiversity with an insect soup and low cost DNA sequencing, according to a University of East Anglia press release.
Douglas Yu, a biology professor and the lead researcher for the study, said analyzing a few hundred ground-up bugs gives researchers equivalent data to traditional intensive methods for a fraction of the cost.
He said, compared to high quality data sets analyzing 55,000 arthropods and birds, sequencing bug juice was just as effective.
The researchers use a process called metabarcoding to identify bugs and biodiversity of an environment.
The measurement could eventually be established as a low cost, low impact way to understand the biodiversity of a system through some of its smallest creatures.Read More
Researchers from a Swiss university found plastic particulate is widespread in Lake Geneva, according to a press release from the École Polytechnique Fédérale de Lausanne.
The researchers sampled the lake in several ways to quantify microplastic pollution. Every sample taken for the study, whether from bird droppings, fish dissection, beach combing or a net drag had plastic particles in it.
No quantity of just how much plastic is in the lake was given in the release. Further studies will evaluate plastic content of lakes and rivers across Switzerland.Read More
River management is inherently complex, demanding mastery of constantly dynamic conditions even when the climate is stable. As the climate changes, however, river management will become even more difficult and unpredictable—and old models and techniques are likely to fail more often.
Now, researchers from around the world are calling for attention and change to how we manage and model the rivers of the world. Dr. Jonathan Tonkin , a Rutherford Discovery Fellow at New Zealand's University of Canterbury , spoke to EM about why he is arguing that current tools for river management are no longer enough as even historical baseline river ecosystem conditions themselves are changing.
