My first post here πŸ™‚

πŸ‘©β€πŸ”¬πŸ’§ Can a few drops of water reveal hidden rice-field pests?
Our new bioRxiv preprint shows how low-cost eDNA can help farmers track native & invasive species efficientlyβ€”no long surveys needed.

The Croucher Foundation, who graciously funded our eDNA workshop, were kind to interview and report on the ongoing research in our lab. It's been a busy start the past couple of years and we are very excited to share more of our results soon. croucher.org.hk/en/news/moni...

Quantifying the Temporal Dynamics of Marine Biodiversity Under Anthropogenic Impacts Using eDNA Metabarcoding This study uses eDNA to explore marine biodiversity changes under anthropogenic impacts, with a focus on marine community dynamics. Through the use of eDNA metabarcoding, the research identified 814 ....

Our new study shows how eDNA can track fine scale marine biodiversity loss under human impacts. Using a large scale mesocosm experiment we monitored temporal dynamics in bio-accumulation, response to stressors and eDNA degradation #eDNA #MarineBiodiversity onlinelibrary.wiley.com/doi/full/10....

Finishing off this season’s #freshwater #macroinvertebrate #eDNA campaign in Tai Lam. Now back to the lab for the rest of the dry season to work through the samples.

Treking through the Northeast end of the New Territories. Few random dog encounters mixed with some nice natural streams. Just shy of our site goal for the season. #eDNA #macroinvertebrates

It's time consuming, but you can make smaller size request (e.g. order, family) and merge them all afterwards.

Yes, they have been mostly ignored in Hong Kong. We've mostly found species that also occur regionally, with ~5-7 entirely new species.

Our initial Hong Kong #Chironomidae survey is done. Elaine is busy making sure we get the traps down before Christmas. Over 200 new additions to the species checklist so far from the sample sorting. #biodiversity

Finished a busy week sampling around the Tai Tam reservoir system. Hong Kong does not have any natural lakes, but the reservoirs help keep a good part of Hong Kong somewhat rugged.

You can have a look at Gert-jan’s CRABS pipeline for downloading data bases and assigning taxonomy . Works well once you get over the technical hump. The overall pipeline works for self adapting as well. onlinelibrary.wiley.com/doi/10.1111/...

Hey everyone. Here is my first attempt at an environmental DNA (eDNA) starter pack. Sorry if there is another one going around. If you would like to be added, let me know and I'll eventually figure out how.
