The common bottlenose dolphin is a cosmopolitan species that can be found worldwide in all oceans except polar and sub-polar waters. This wide distribution associated with certain level of morphological variation, which seems consistent the presence globally distributed pelagic/offshore ecotype several coastal/inshore ecotypes along continental shelf. In Mediterranean Sea, regularly occurring second most sighted cetacean after striped dolphin. According to some studies, more closely related...
Between 2019 and 2021, 21 bottlenose dolphins were found stranded dead along the Ligurian Pelagos Sanctuary coast (Italy). For 11 animals, out of a total 14 recovered, cause death was classified as natural, anthropic, or not determined based on gross histological pathology ancillary testing. Hexachlorobenzene (HCB), dichlorodiphenyltrichloroethanes (DDTs), polychlorinated biphenyls (PCBs) examined in their blubber, results discussed according to toxicological properties. All specimens showed...
Information regarding bacterial diseases in Cuvier’s beaked whale (CBW, Ziphius cavirostris) is scattered and mostly incomplete. This report describes a case of septicemia by Morganella morganii juvenile male CBW with concurrent renal crassicaudiasis. The animal stranded along the Ligurian coastline (Italy) underwent systematic post-mortem examination to determine cause death. Histopathology showed lesions consistent septicemic infection, severe meningoencephalitis, An M. alpha-hemolytic...
Abstract Information on movements and connectivity among populations of animals is important for the delineation units to conserve, so that demographic parameters, such as abundance, fecundity mortality, can be placed in an appropriate population conservation context. Common bottlenose dolphins ( Tursiops truncatus ) are often considered relatively ‘resident’ demonstrating strong site fidelity specific areas. However, this perception may partly artefact distribution ‘habitat use’ cetacean...
Abstract Despite attacks of bottlenose dolphins towards conspecifics and other species being reported worldwide, inside the Mediterranean Sea these behaviours are still considered sporadic have been, to date, only recorded in Spain France, mostly directed striped dolphins. In this work, we necropsy outcomes a dead dolphin that suggest fatal interaction with Italian side Pelagos Sanctuary, Western Ligurian Sea. Results from post-mortem examination showed multiple, multifocal external rake...
This study represents the first complete assessment of population dynamics and residency common bottlenose dolphins in Western Ligurian Sea, an area where dolphin sightings have been rare past. Despite being greatly affected by human pressure, information about this is poor sporadic. The took place from April 2018 to December 2020. One hundred seventy‐one dedicated boat surveys were performed year‐round resulting 95 sightings, 123 individuals identified through mark‐recapture...
Abstract Research in the western Mediterranean has shown that sperm ( Physeter macrocephalus ) and Cuvier's beaked whales Ziphius cavirostris are present as small, globally distinct populations face numerous threats. The eastern is not well studied, few surveys have investigated composition of cetacean communities. In this study, visual‐acoustic were conducted off coast Israel during April–May 2022 to characterize community. Sperm (three encounters), (one encounter), bottlenose dolphins...
In the Ligurian Sea, northern part of Western Mediterranean sperm whales (Physeter macrocephalus Linnaeus, 1758) are historically sighted as solitary individuals or loose aggregations males, while social units extremely occasional. On 21 August 2020, two different were recorded in this area with an estimate total (12 first and nine second). The whale subpopulation is considered Endangered under IUCN Red List understanding its movements structure lacking. These observations increase our...
In this work we revise past observations of Long-tailed Jaeger Stercorarius longicaudus in Italy and its ecological features Northern Italy. Moreover, report the new observation species realized August 2020, an individual juvenile plumage that was spotted front town Imperia. The identification based on pictures taken during sighting. record, following one Genoa 1991, is second for Ligurian Region, it first sighting western part region.
