Re: Bad incident, take some caution

Cripes, such an easy mistake to make. Sorry to hear about the fish. Make sure as many people hear about this as possible. I also find it hard to believe that it's the ethanol, as there will only minute amounts left on the hands after they are are dried, and I doubt it's that toxic in such small quan...

Hey Jools,

It looks like <"it is another one for ">, @racoll's", <"Spreadsheet of shame">. :) Presumably one could check the Genbank accession numbers of the comparative sequences to see if those have been correctly identified. They look legit. I checked COI and 12S. Wild caught vouch...

Re: Deciding on catfish for African river tank

Hey Marc! Those Amphilius I got at Pier at the CSG meeting are fantastic, so I thoroughly recommend them if you can find any. They're incredibly lively and go absolutely mental if they smell any food. Main problem with African fishes, as you know, is actually finding them in the shops. Only option r...

Great to catch up with everyone! Thanks Mark and the other organisers.

Hopefully we'll all still be around for next year.

No, but there really should be ... In its place I have a "spreadsheet of shame" that I use to filter out any undesirable sequences before I use them. Problem is it needs manually updating and that takes work :( Some of my favourites are: Solea solea identified as Xiphias gladius Thunnus id...

I don't mind them publishing papers that nobody will read, but when put this crappy data on public databases, it really bothers me. This one , apparently "Tatia intermedia", is actually a goldfish! See https://blast.ncbi.nlm.nih.gov/Blast.cgi?PAGE=Nucleotides&PROGRAM=blastn&QUERY=M...

Re: Microcambevinae, new subfamily in Trichomycteridae

Making phylogenetic assumptions based on a small amount of data can likewise be very misleading. With a small amount of data those incorrect relationships tend not to be well supported, and so the gut feeling is that with more data they will be resolved. They often are resolved with 100% support .....

Re: Microcambevinae, new subfamily in Trichomycteridae

It's increasingly common now to use entire genomes for phylogenetic reconstructions. But what always staggers me is how well the crappy old methods can still perform. Take the recent loricariid phylogeny by Roxo et al. (2019) using 328,330 bp of ultraconserved element DNA ... I get much the same top...

Re: History of Ancistrus in the US

In short, it maybe is time to re-introduce "Ancistrus sp(3)" Remember this thread ? Sadly very few additional Ancistrus DNA barcodes have been publicly uploaded since 2012, but I ran the analysis again to see if anything has changed. We do now have some trade samples from both South Afric...

Why publish one paper when you can publish ten?! Just gaming the system, unfortunately, and not adding much value.

Oops, my bad. No idea where 2017 came from. That's the paper (2013).
