Article
The distinctive features and fossil content of some caves from eastern Sicily (San Teodoro, Donnavilla, Fulco, Taormina, Tremilia, Spinagallo), altogether spanning from the middle Pleistocene until the beginning of the Holocene, are discussed. Although dating on vertebrate and/or invertebrate remains is available in few instances, coastal notches a...

Copepods of the family Pandaridae are typically ectoparasites of elasmobranch fishes. They display a cosmopolitan distribution and limited host specificity. Published literature on their occurrence on pelagic sharks in the Mediterranean is scarce, often from the past century, or scattered through fish parasite surveys. Moreover, of the 64 valid pan...
Article
The first finding of Halyomorpha halys in the island of Rhodes, Greece, is reported and the fast range expansion of this invasive species over the Aegean region is briefly discussed.

Two juveniles Luvarus imperialis, astrodermella stage, 97.4 mm and 90.6 mm in total length, were recorded on September 2016 and August 2017 respectively, the first caught by a bottom trawler off the southeastern coast of Sicily, Strait of Sicily, Italy, the second found stranded on the beach in the nearby region. Biometrics data of this uncommon sp...

Considerable research effort has recently been invested into the reporting of Non- Indigenous Species (NIS) within the Mediterranean Sea, with species’ first records from the Basin holding most prestige within the biological community. This invariably leads to a discard of secondary, unpublished records, which represent a vast repository of informa...

We here describe turtle remains from the late Miocene (Tortonian) of Cessaniti (Calabria, southern Italy), an area that recently has been palaeogeographically reconstructed as being, at that time of the Neogene, directly connected (or at least rather proximate) to northern Africa, instead of Europe. The material pertains to three different turtle c...

Excavations conducted in 2006 inside San Teodoro Cave (north-eastern Sicily) retrieved remains of Hippopotamus pentlandi; of a medium-sized, dwarf Palaeoloxodon; and of Ursus cf. arctos. The specimens were found under a blackish phosphatic crust, dated to about 120 ky. This stratigraphic position sets an important constraint on the arrival time of...

Abstract Good datasets of geo-referenced records of alien species are a prerequisite for assessing the spatio-temporal dynamics of biological invasions, their invasive potential, and the magnitude of their impacts. However, with the exception of first records on a country level or wider regions, observations of species presence tend to remain unpub...

According to Boldrocchi et alii (2017) the information on the diet of white sharks in the Mediterranean inferred from stomach content analyses of 103 stomachs revealed among other prey items 45 bony fish and 5 cartilaginous fish. The most common teleost prey groups were tuna (Thunnus spp.) and swordfish (Xiphias gladius). In the Strait of Messina m...

Coronuloid barnacles are epibionts of several marine vertebrates (including cetaceans and sea turtles) as well as invertebrates, and are assigned to two families of turtle barnacles (Chelonibiidae Pilsbry, 1916 and Platylepadidae Newman & Ross, 1976) and one family of whale barnacles (Coronulidae Leach, 1817). Chelonibiids and coronulids have a sca...

A flourishing population of the Massawan mantis shrimp, Erugosquilla massavensis, an Erythraean species, is recorded off Sicily, Italy, one year after the very first specimen was collected off the eastern coast of the island. The species is already established as a minor, albeit valuable, fishery resource. Once its population increases, however, it...

Invasive species can cause significant changes in local and regional ecologies, especially in freshwater ecosystems. It is thus important to monitor and document the spread of non-indigenous species to such habitats as such information can be critical to preserving habitats and species. We document the spread of the red swamp crayfish Procambarus c...

Stable isotope analysis is a useful tool for studying the ecology of marine consumers, as carbon (δ¹³C) and nitrogen (δ¹⁵N) isotope ratios may reflect individuals’ patterns of diet and habitat use. Knowledge of foraging strategies has significant implications for the conservation of endangered loggerhead turtles Caretta caretta (Linnaeus, 1758). In...

The pygmy right whale, Caperea marginata, is the most enigmatic living whale. Little is known about its ecology and behaviour, but unusual specialisations of visual pigments, mitochondrial tRNAs, and postcranial anatomy suggest a lifestyle different from that of other extant whales. Geographically, Caperea represents the only major baleen whale lin...

Sea turtles' reproductive disorders are underdiagnosed; but potentially several diseases may affect gonads, genitalia, and annexes. Viruses, bacteria, and parasites may cause countless disorders; but more frequently the cause is traumatic or linked to human activities. Furthermore, veterinary management of the nest is of paramount importance as wel...

The nesting activity of the sea turtle Caretta caretta in Sicily (southern Italy) has long been declining but in the latest years a substantial resumption of nesting occurred there, related to several factors. Recently, nests were found more frequently, leading to reconsider the importance of this reproductive area for the species in Italy. We anal...

Our knowledge about the evolutionary history of coleoid cephalopods is mainly based on a few evolutionary windows. In particular, palaeogeographical data is strongly limited; every new fossil locality yielding coleoid remains is therefore of exceptional interest. Here, we describe the first coleoids from the Upper Cenomanian of Sicily (southern Ita...
