Just published 'Dietary Differentiation Between Sympatric #Ecotypes of #Astatotilapia calliptera From Lake Masoko, #Tanzania Revealed by Metabarcoding'! bit.ly/3GTRKjI Great to be part of this work led by Dr Kirthana Pillay (FSBI PhD)! Nostalgic, given that my MSci thesis looked at these #cichlids!

Last session of #UKDNAWG25 is standards, best practice, current knowledge gaps and future opportunities. @leeselab.bsky.social discusses how we go from wild west of #eDNA to standards. Challenges are limited comparability of methods and unequal access to technical infrastructure and funding.

Different labs can produce vastly different results which leads to ‘eDNA doesn’t work’ - ring and proficiency testing is key. Establishing minimum standards (e.g. sequencing depth) and metadata reporting is crucial. Stringency of standards will vary by taxonomic group #UKDNAWG25

Similar functional traits across methods - ecological resilience or full range of traits not captured? #Ecoacoustics detects distinct traits compared to larger mammals with other methods. #Ecoacoustics and #eDNA needed for most comprehensive trophic network #UKDNAWG25
