- The study investigates the genetic distinctness of two subspecies of Cirillo found in central and southern Italy, using nuclear and chloroplast markers.
- The research reveals that one subspecies is more genetically uniform and restricted to mountainous areas, while the other shows greater variability and a wider geographical range.
- Both subspecies have similar ecological needs but inhabit different temperature zones, and predictions indicate that their distribution may significantly shrink over time.
Intergeneric hybrid origin of the invasive tetraploid Cirsium vulgare.
Plant Biol (Stuttg)
August 2024
The invasive tetraploid Cirsium vulgare hybridizes with both Cirsium and Lophiolepis. Its conflicted position in molecular phylogenies, and its peculiar combination of morphological, anatomical, and genomic features that are alternatively shared with representatives of Cirsium or Lophiolepis, strongly suggest its intergeneric hybrid origin. Genetic relationships of C.

Unfortunately, due to an error in the required citation of the basionym, the name "Cavernulicola chilensis" was invalid and cannot be accepted as the generitype of Cavernulicola. This means that Cavernulicola, Cavernulicolaceae, and Cavernulicolales are likewise invalid names under the provisions of the International Code of Nomenclature for algae, fungi, and plants (ICN, Shenzhen Code).

- Despite many studies on alien plant species, their spread and negative effects on habitats are still hard to control in Italy and Europe.
- This research examined 12 Italian regions, documenting 117 new records of alien plants, including 89 first-time sightings and 7 new species for Italy, two of which are new to Europe.
- Key regions like Calabria, Sardegna, and Sicilia recorded the most instances, with five of these newly identified taxa classified as invasive in Italy, highlighting the importance of plant studies in understanding and managing alien species.
