Just found this in iNaturalist: Probably the first mention of the invasive flatworm Caenoplana variegata in Morocco, and also the first for all Africa! www.inaturalist.org/observations...

Orthoptera are infected by about 60 species of gregarines assigned to the genus 𝙂𝙧𝙚𝙜𝙖𝙧𝙞𝙣𝙖. This paper confirmed that Gregarina garnhami and G. acridiorum, parasites of Schistocerca gregaria and Locusta migratoria, are distinct species [2021🧪] More: doi.org/10.1051/para...

📢Depuis son investiture le 20 janvier, Donald Trump a pris des décisions qui vont sérieusement nuire à la recherche scientifique aux États-Unis, avec des répercussions mondiales, notamment sur les collaborations internationales. #Science #Recherche #USA #CollaborationsInternationales #Innovation

La "Microscopie Électronique Végétative" vous connaissez? Affreux exemple de mauvais emploi de l'IA et de mauvaise foi des revues retractionwatch.com/2025/02/10/v...

Interesting preprint: again, something new about the origin of the Bilateria! Also, an excellent example of a title not making the communication with the general public easy...🧪 "The xenacoelomorph gonopore is homologous to the bilaterian anus" doi.org/10.1101/2025...

Aujourd’hui… 😀

Demain, conférence publique à Pibrac, 20h30 🧪 "Les Plathelminthes" On pourra y assister en personne ou à distance www.jardinnaturepibrac.org/Agenda%20Jar...

Ma conférence du 7 février maintenant annoncée dans La Dépêche www.ladepeche.fr/2025/02/04/c...

This paper described the morphology of the monogenean Protopolystoma xenopodis which infects the African clawed frog Xenopus laevis. Including a SEM study of the 𝗼𝗻𝗰𝗼𝗺𝗶𝗿𝗮𝗰𝗶𝗱𝗶𝘂𝗺, the free-living stage of the monogeneans (image) [2014🧪] More details: doi.org/10.1051/para...

A search for "Strudelwürmer" (Flatworm in German) in Google show that the press is highly excited about a new finding of Caenoplana variegata in Germany. 🧪

The first discovery of the flatworm Caenoplana variegata now in the Austrian press 🧪 "Fleischfressende Strudelwürmer breiten sich aus"

Diversity of apostome ciliates, Chromidina spp. , parasites of cephalopods of the Mediterranean Sea [2016🧪] This paper describes a new species, Chromidina chattoni found in Loligo vulgaris off Tunisia More details: doi.org/10.1051/para...

Nice new work on monogeneans!

Ma prochaine conférence sur les Plathelminthes est annoncée. 7 février, 20h30 www.lepetitjournal.net/31-haute-gar...

This seems to be the first record of the invasive land flatworm Parakontikia ventrolineata from Germany (I received the PDF but could not find a source online)

Agreed 😀! However, please note that most of us scientists are more comfortable with a 🔬than with a 🎸 ...

Species of Philometra (Nematoda) from fishes off the Mediterranean coast of Africa [2017🧪] These nematodes have 𝗴𝗶𝗮𝗻𝘁 𝗳𝗲𝗺𝗮𝗹𝗲𝘀 visible in the gonads of the fish, while the males are very small. More details: doi.org/10.1051/para...

The sclerotized structures of monogeneans have traditionally been studied by light microscopy and different staining techniques. This 2017 paper explored other methods, including scanning electron microscopy (SEM) 🧪 More details: doi.org/10.1051/para...

In 2021, we reported, for the first time, the presence of the invasive land flatworm 𝘗𝘭𝘢𝘵𝘺𝘥𝘦𝘮𝘶𝘴 𝘮𝘢𝘯𝘰𝘬𝘸𝘢𝘳𝘪 in Guadeloupe, Martinique & Saint Martin (French West Indies).🧪 Since this date, new records show that the species has spread in many places. More details: doi.org/10.11646/zoo...

This is Bipalium admarginatum, a flatworm species described in 1933, never seen since. We found it in Malaysia and studied its complete mitogenome. 🧪 More details: doi.org/10.11646/zoo...

Le Code de conduite européen pour l’intégrité en recherche (2023) est maintenant disponible en français (2025). Lecture indispensable. Cela dit, si vous travaillez correctement, aucune surprise!

Hammerhead flatworms: In this paper, we studied the mitochondrial genomes and described two new species from France, Italy, and Mayotte 🧪 [2022] doi.org/10.7717/peer...

Our short popular piece about the discovery of the rarely seen Bipalium admarginatum. It's filled with humour 😀 and science🧪 doi.org/10.6084/m9.f...

Adult nematodes were found in 3 species of sharks, Galeocerdo cuvier, Triaenodon obesus, and Stegostoma fasciatum from New Caledonia. These nematodes were assigned to 2 newly established genera, Euterranova and Neoterranova [2020 🧪] doi.org/10.1051/para...

🧪 In this paper, I summarized our research on the invasive flatworms Bipalium kewense, Caenoplana coerulea, C. decolorata, C. variegata, Diversibipalium multilineatum, Marionfyfea adventor, Obama nungara, Parakontikia ventrolineata, and others... doi.org/10.1590/S198... #openaccess

In this paper, we characterized the complete mitogenome, the ribosomal cluster, and other genes of Tristoma integrum. We also discussed the taxonomy of the species, since Tristoma was one of the first described monogeneans, by Cuvier in 1817. 🧪https://doi.org/10.1051/parasite/2023016

Les incendies de Californie me rappellent cet article que nous avions écrit en 2020, à propos des animaux morts pendant les grands incendies en Australie. L'idée était de montrer qu'on oublie toujours de compter les milliards d'invertébrés dans tous les milieux. 🧪 doi.org/10.6084/m9.f...

Some journals are less serious than others. Some Editors just do not read the list of references. 🧪 I just found that my 2006 paper on parasites of fish in the Pacific was cited in a paper... on the social impact of the trade of nuts in Northern Pakistan 😂 doi.org/10.70670/sra...
