🐟 Global migratory fish populations have declined by 81% since 1970
📉 Due to habitat degradation - particularly river barriers - human over-exploitation, pollution & climate change
🌿 But positive signs that restoration can help reverse trend

Received the eTA for my trip to Kenya this weekend. Really looking forward to the @JRSBiodiversity sponsored workshop next week. We will be doing some fishes and terrestrial insects as well. Now to print and bind all the protocols and get any last minute supplies!
For anyone interested in teaching or learning PCR and DNA barcoding, here’s some recommended reading: four articles written by DNA barcoding educators describing lesson plans, learning objectives, and experiences running their courses.
For teachers, these articles might be useful to build, structure, or improve a course.
For learners, they might provide interesting insights into what to learn and practice from a “teachers’ lesson plan” perspective, going way beyond what a basic protocol might offer.
All of these studies had very similar aims but used different methodological approaches in terms of DNA extraction, software, and course length. So there are plenty of methodological options to look into and find out what suits you best.
⭐ The first article, by Erasmus (2021), describes DNA barcoding as a component of a third-year biochemistry course in British Columbia, Canada. The lesson plan involved a one-hour lecture and two three-hour laboratory sessions based on DNA barcoding stoneflies (Plecoptera).
The practicals used Chelex resin for DNA extraction; FinchTV for chromatogram inspection and editing; and the Barcode of Life Data Systems (BOLD) and NCBI’s GenBank for sequence identification:

⭐ The second article, by Shevcenko et al. (2019) covers a course of 10 one-hour sessions framed around the DNA barcoding of caddis flies (Trichoptera) in New Jersey, USA.
Over this course the students learned about sample collecting; insect diversity; vouchering and photographing of collections; extracting DNA using the HotSHOT method; PCR of the COI barcode region; gel electrophoresis amplicon visualisation; Sanger sequencing; editing DNA sequences; uploading results to the Barcode of Life Data Systems (BOLD); and phylogenetic analysis.

⭐ A third article, by Casanova & Shumskaya (2021), covers the DNA barcoding of fungi over three laboratory classes. The practicals used a spin column kit DNA extraction (Powersoil from Qiagen), and DNA analysis via NCBI’s BLAST search tool and free MEGA phylogenetics software:

⭐ And finally, for those short of time or for remote homework purposes, two simple exercises by Al-Deeb (2021) in basic BLAST searching and phylogeny construction using the online https://t.co/wgUd48aWz5 tool, designed as a basic introduction and to break through barriers arising from the fear of bioinformatics:
