Read the linked blog. It has a detailed description of the questionable editorial practices at three successive MDPI journals with the same deeply flawed paper

Anthony Ricciardi@ecoinvasions.bsky.social · 9mo ago

No paper from me or my lab will ever be submitted to an MDPI journal - including any of their superfluous "special issues". I will very rarely (if ever) cite MDPI papers. And I will never review for them. deevybee.blogspot.com/2024/08/gues... The same goes for FrontiersIn journals, among others.

I did research, too! 😮 Out right now in EJPP: Carrot storage diseases predominantly caused by mixed fungal infections PK, S Latvala, M Haapalainen, S Velmala, @tainapennanen.bsky.social & T Suojala-Ahlfors (EJPP) doi.org/10.1007/s106... 26 fields, 2500kg carrots, 33 000 individually inspected :)

Carrot storage diseases predominantly caused by mixed fungal infections - European Journal of Plant Pathology

Fungal pathogens often cause severe post-harvest losses in stored carrot yields. In 2020 and 2021, carrot samples were collected in Finland from 26 fields with different soil types. The proportion of symptomatic carrots was assessed at two time points during the cold storage period. To analyse the occurrence of different fungal pathogens in the symptomatic carrots, DNA samples were prepared and tested for the presence of fungal pathogens by species-specific PCR. The most frequently detected pathogens were Cylindrocarpon spp. with 61% occurrence, followed by Fusarium avenaceum (44%), Mycocentrospora acerina (42%), Botrytis cinerea (12%), and Alternaria spp. (0.8%). B. cinerea and F. avenaceum were more common in carrots grown on organic soil, while M. acerina was more common in carrots grown on mineral soils. Mixed fungal infections were overrepresented in the symptomatic samples, in particular, Cylindrocarpon spp. often occurred together with F. avenaceum and M. acerina in the same samples. Amplicon sequencing of the fungal internal transcribed spacer region from the DNA of symptomatic tissues revealed that in addition to the pathogens—B. cinerea, M. acerina, Cylindrocarpon spp. and Sclerotinia sclerotiorum—the hyphomycete fungi Tetracladium spp. and the yeast Leucosporidium intermedium were abundant, and that Tetracladium spp. were more abundant in the carrots infected with M. acerina. A pathogenicity test confirmed that F. avenaceum is pathogenic to both the new season and old season carrots.

Scientists have seen Asgard archaea crawling for the first time. When it comes to the origin of eukaryotes, this is like seeing a feathered dinosaur in the wild. (Video courtesy of Philipp Ralder)

Journal publishers *are* bundling your papers up in "data licensing agreements" for big tech companies to use for AI model training. Our publisher, T&F, got £75m from Microsoft for that last year alone.

We're experiencing an unbelievable deluge of submissions. At our journal we got ~200 per year in 2020. Last year it was 600. This year it's 800 with several months to go. So that's why we're slower to get stuff out for review.

Happy May Day eve from empty late-afternoon office! What am I doing working late before holidays? Well, plating a few dozen Pythium samples from lettuce roots collected on Monday. @marikara.bsky.social shows a great example of possible symptoms: small roots and slow growth despite green color. 😊
