“…In a recent study on predatory holes found in some of the specimens of J. cordata and A. cuneata analysed here (Evangelisti et al . ), a size preference of predators for individuals having length values >1.9 mm was found for J. cordata . This means that larger individuals were preyed upon more frequently, whereas smaller individuals were less affected by predation.…”

“…The analysis was carried out on samples from the Marine Protected Area ‘Secche di Tor Paterno’, Central Tyrrhenian Sea, as part of the biodiversity study of the area (Albano & Sabelli ; Evangelisti et al . , ). The distributions were examined for the two species separately and, within each species, for the three different death assemblages which the specimens came from: within the coralligenous substrate, within a Posidonia oceanica meadow, and from sand channels containing specimens originated from the nearby coralligenous substrate and Posidonia meadows.…”

Size-frequency distributions can support reliable inferences concerning population dynamics of brachiopods, but only a few data are available so far. In this study, length and width frequency distributions of dead specimens of the Recent brachiopods Joania cordata and Argyrotheca cuneata from the Marine Protected Area 'Secche di Tor Paterno', Central Tyrrhenian Sea, Italy (41°35′ N, 12°20′ E), are reported in order to add new data about sizefrequency distributions of brachiopods. The studied specimens came from death assemblages in the coralligenous substrate, in the Posidonia oceanica meadows, and in the sand channels. The observed patterns vary from leftskewed (J. cordata) to right-skewed (A. cuneata), indicating respectively a low and high mortality of smaller individuals. Significant differences between the coralligenous substrate and the P. oceanica meadow were observed for both species, revealing a variation among different habitats. All length and width distributions are clearly polymodal, but the biological meaning of the peaks is difficult to interpret, as the two species seem to have a 2-year life span. A biometric analysis of shell sizes revealed that length and width are the most variable parameters during the growth of the animal.

Mediterranean brachiopods are elusive organisms to find alive even if the bathymetric range of some species extends to very shallow waters. We here record an abundant population of Joania cordata (Risso, 1826) and Argyrotheca cuneata (Risso, 1826) in the rhizome layer of a Posidonia oceanica (Linné) Delile, 1813 meadow in Plakias, southwestern Crete from 5 to 20 m depth. Altogether, we collected 963 living individuals and 4309 shells by suction sampling; it is the largest collection of living brachiopods in Posidonia meadows ever reported. Although literature records on the occurrence of shallow-water brachiopods in this habitat are few, we claim that Posidonia rhizomes are a particularly suitable infralittoral habitat for these organisms due to their sciaphilous conditions. Suction sampling is an effective technique to collect them and can enable the discovery of many more populations in the Mediterranean Sea.

“…Only some rare reports were published on their occurrence in Posidonia meadows. Taddei Ruggiero (1985) has found death assemblages in S Italy, while Evangelisti et al (2011) reported both living specimens and shells from the seagrass covered areas of an offshore reef in the Tyrrhenian Sea.…”

Abstract. The topmost Argille Azzurre (beds 1-2) and the basal Sabbie di Asti (beds 3-9) formations in the Villalvernia area are analysed in terms of palaeoecological and taxonomic features; the succession is 6 m thick and dates back to the middle Piacenzian within the Globorotalia bononiensis acme. The upper boundary of the clayey Bed 2 corresponds to an unconformity reflecting Pliocene tectonic activity. The study is focused on the fossil assemblages of beds 3, 4 and 9. The sandy Bed 3 yields 362 mollusc taxa; their assemblage is allochthonous and mixes infra- to circalittoral species accumulated by hyperpycnal mass-transport. The same mechanism is responsible for the origin of the overlying fossil unit (Bed 4) with numerous specimens of the Entobia-Gastrochaenolites ichnofacies. The autochthonous fossil assemblage of Bed 9 yields 308 molluscs, plus three brachiopods and ten fish taxa; most of them refer to the Posidonia meadow (HP), and their autochthony is shown by taphonomic features as skeletal integrity, mixing of successive generations or the limitation to juvenile ontogenetic stages of vagile and temporarily byssate species for which the HP performs a nursery function. Three brachiopods and 52 molluscs are here reported for the first time from the Pliocene of Piedmont. In the final chapter “Systematic Palaeontology” four brachiopods and 29 molluscs are described, among which there are eight new gastropod species: Crepidula bellardii n. sp., Conus dellabellai n. sp., Conus villalvernensis n. sp., Odetta chirlii n. sp., Ondina curta n. sp., Ondina elongata n. sp., Ondina pseudovitrea n. sp., Anisocycla subcylindrica n. sp.
