Australoplana sanguinea. 3, specimen MNHN JL472, unscaled;

Maximum likelihood phylogenetic tree of the three Mitosporidium species and their relatives, based on concatenated amino acid sequences. Based on the dataset by Haag et al., 2014 [46], added with the sequence of Paramicrosporidium saccamoebae and the sequences obtained in the present study for Mitosporidium Mtspo_JL467 and Mitosporidium Mtspo_JL472. The three Mitosporidium species are in a strongly supported clade, sister to Rozella allomycetis, which displays a very long branch, and P. saccamoebae is sister-group to the clade containing Mitosporidium and Rozella. Support indicated at the nodes.

New paper out!
In Northern Ireland, two invasive land flatworms turned out to host two new Microsporidia species — in a genus that used to have only one.
Genomes revealed a true Irish cocktail of flatworm, earthworm & parasite DNA.

Co-occurrence patterns of introduced terrestrial flatworms in metropolitan France revealed by citizen science - Biological Invasions Terrestrial flatworms are a group of successful carnivorous invaders that have been introduced to many regions outside their native range. In France, six different species have been recorded in significant numbers over the past 20 years, with a recent increase in observations. These include predators of earthworms, gastropods and soil arthropods. Their presence raises concerns about their potential to disturb communities of soil-dwelling organisms. Here, we aimed to describe patterns of co-occurrence between these species in France, using a national inventory of alien flatworms coupled with estimates of potential co-occurrence derived from ecological niche models trained at the global scale. We showed that, although alien predatory flatworms are relatively widespread in France, they co-occur less frequently than expected simply based on each species’ respective environmental suitability, i.e., they tend to be found alone and not in association with other alien flatworm species. However, ecological niche models indicate a high potential for more frequent co-occurrences in the future. We hypothesize that their limited dispersal ability and their relatively recent introduction has confined most species close to their introduction sites. However, if they eventually fill out their potential range, predators of different taxonomic groups will co-occur more frequently, leading to greater predation pressure in invaded ecosystems. Our conclusions shed light on the current and future co-occurrence patterns of alien predatory flatworms in France. Understanding how they translate in the field in terms of predation and competitive interactions will be crucial for predicting the impact of flatworm invasion on soil ecosystems.

🧪 Les vers plats terrestres envahisseurs sont bien présents en France — mais ils évitent la colocation !
Notre nouvelle étude basée sur la science citoyenne révèle qu’ils coexistent moins souvent qu’attendu, même si les modèles indiquent que cela pourrait bientôt changer.

Meet Obama nungara, a South American flatworm now found in three-quarters of metropolitan France. Over 530 citizen reports over 5+ years, and molecular evidence shows two Argentine clades behind Europe’s spread.
Still threatening soil fauna? Possibly.

The rapid rise of land #flatworms throughout Europe is of particularly concern, and the international trade of ornamental plants can represent a pathway for the spread of these #InvasiveAlienSpecies, some of which are already listed as of Union concern under EU Reg. 1143/2014.

Pure bloodlines? Ancestral homelands? DNA science says no. — Harvard Gazette Geneticist explains recent analyses made possible by tech advances show human history to be one of mixing, movement, displacement.

“The big perspective change from ancient DNA study is that people living today are almost never the descendants of the people in the same place thousands of years before”
