Stylochus mediterraneus (Turbellaria: Polycladida), predator on the mussel Mytilus galloprovincialis
The polyclad Stylochus mediterraneus Galleni has been found associated with the mussel Mytilus galloprovincialis Lmk., on which it feeds. Polyclads allowed to feed freely on groups of mussels of…

- 1 November 1999
A new view of the evolutionary history of the phylum Gastrotricha is put forward, in which Chaetonotida, and not Macrodasyida, are the most primitive forms of the group, contrary to the commonly held view.
The Interrelationships of the Gastrotricha Using Nuclear Small rRNA Subunit Sequence Data, with an Interpretation Based on Morphology
Analysis of partial sequences of the 18S rDNA gene of 18 taxa to test morphological estimates of gastrotrich phylogeny and to verify whether controversial interrelationships from previous molecular data are due to poor sampling results are generally compatible with the hypothesised evolutionary scenario based on morphological data, but are in contrast with previous findings from molecules.
Marine gastrotrichs from the Tremiti Archipelago in the southern Adriatic Sea, with the description of two new species of Urodasys
The number of species found was relatively high and comparable with the range of fauna found on the major Italian islands, and a possible evolution of the reproductive system in the genus Urodasys is briefly discussed.

Patterns of Diversity in Soft-Bodied Meiofauna: Dispersal Ability and Body Size Matter
The macroecological analysis of meiofauna indicates that not only body size but mostly dispersal ability and also occurrence in the endobenthic habitat are important correlates of diversity for these understudied animals, with different importance at different spatial scales.
Meiofauna of the Adriatic Sea: present knowledge and future perspectives
Owing to technical problems and difficult taxonomic identification, meiofauna have been generally less studied than macrofauna. However, the role of meiofauna in marine ecosystem functioning, and…
Meiofauna densities and gastrotrich community composition in a Mediterranean sea cave
Results indicate that for meiofaunal taxa living in a Mediterranean, semi-submerged sea cave, the marine caves may represent hotspots of biodiversity and endemism; the driving forces at the base of the trophic depletion hypothesis seem to be responsible for structuring the meioFauna community inside the cave.
Yellow-bellied marmots (Marmota flaviventris) 'in the shape space' (Rodentia, Sciuridae): sexual dimorphism, growth and allometry of the mandible
Morphological remodelling in the yellow-bellied marmot mandible seems to be more concerned with changes in size and behaviour during growth than with ethological differences between adults of the two sexes.
