6th iBOL Conference

Post Image

Arne Beerman and Vasco Elbrecht have presented new research from the GeneStream project on the 6th International Barcode of Life Conference in Guelph (Canada). Arne Beermann compared morphological identifications and DNA barcoding of marcoinvertebrates and provided an overview of the state of DNA reference databases. Vasco Elbrecht presented new metabarcoding protocols, and stressed the issue that primer bias prevents the estimation […]

New Publication

Post Image

A new paper by Vasco und Florian has just been published in PLOS ONE. In the study, we were able to detect over 80% of invertebrate taxa from a bulk samples using DNA metabarcoding. Further more we showed that with PCR based methods, estimating taxon abundance is not possible in such diverse bulk samples. Monitoring should thus focus primarily on presence absence data […]

New Lab ‘member': Tissue homogeniser for metabarcoding samples.

Post Image

DNA metabarcoding allows the identification of hundreds of specimens at the same time. This holds great potential for the assessment of freshwater and other ecosystems. However, the appropriate homogenisation of bulk samples for DNA extraction is critical, as we have shown in a recent study. For our future metabarcoding studies using complete benthic kick samples […]

Science Communication course

Post Image

Science communication is really important! Vasco Elbrecht has meet up with Eric Francavilla to learn more about science communication. Eric Francavilla works together with scientists at the Pacific Northwest National Laboratory in Richland, Washington and helps scientists to communicate their findings to the public. Like the GeneStream Team, he is also producing YouTube videos. We learned many useful and specific things and […]

SFS 2015 meeting, USA

Post Image

Vasco presented results of our latest metabarcoding experiments and protocols on the Society for Freshwater Sciences, SFS 2015 in Milwaukee. Our DNA based method for biodiversity assessment in rivers works reliably, but we could show that it will be dificult to obtain abundance data on invertebrate species sampled. The paper has been formally accepted by […]

Genome of the Arizona Snowfly published!

Post Image

We are happy to announce the publication of the mitochondrial genome of the Arizona Snowily Mesocapnia arizonensis (Plecoptera, Capniidae). This is already our second plecopteran genome which we assembled from existing next generation sequence data. We would like to thank Stacey Lance who publicly provided the Illumina data we used on NCBI. Our publication is available […]

Metabarcoding: Samples from Finland!

Post Image

In cooperation with Kristian Meissner from the Finnish Environment Institute SYKE we will start our first big metabarcoding test soon. In the next weeks we will analyse thousands of invertebrates from 30 finish streams with DNA based metabarcoding methods. Picture 1: Over 30 samples are ready for processing in the laboratory. Picture 2: Many samples contain […]
