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...
Morphological changes during body development measurements are crucial in understanding growth rates, allometric relationships, and sexual dimorphism. Recent advances drone technology provide a new perspective enabling an indirect, non-invasive morphological assessment of free-ranging cetaceans. In this study, 10 parameters were measured examined with drone-based aerial photogrammetry across 82 individual fin whales (Balaenoptera physalus) along the Catalan coast Northwestern Mediterranean...
Fatal disseminated toxoplasmosis was diagnosed in a Risso's dolphin (Grampus griseus) dam and its fetus on the basis of pathologic findings, immunohistochemistry, structure parasite. The stranded alive Spanish Mediterranean coast died few hours later. At necropsy good condition. From standpoint pathology, however, it had generalized lymphadenomegaly splenomegaly, enlargement multifocal hemorrhage adrenal glands, diffuse mucosal glandular pyloric stomach, ulcerative glossitis stomatitis,...
Ten species of cetaceans coexist in the Mediterranean Sea, one richest seas biodiversity and endemisms worldwide. The conservation status has been a concern for many years, particularly due to increasing anthropogenic threats such as global warming overfishing. We established stable isotopic niches carbon, nitrogen, sulphur five inhabiting northwestern Sea elucidate mechanisms coexistence. fin whale exploited epipelagic habitats with low trophic level; bottlenose dolphin was mostly neritic...
Drones have become a crucial research tool across marine environments over the past decade, being specifically useful in mammal research. Fin whales (Balaenoptera physalus) been monitored feeding along Catalan coast, Spain (NW Mediterranean), since 2014. To overcome issues such as distance between whale and vessel or lack of distinctive dorsal fin features, an aerial identification technique was developed. It uses whales’ characteristic central chevron pattern (CCP) blaze, which are clearly...
Biologging and habitat modelling are key tools supporting the development of conservation measures mitigating effects anthropogenic pressures on marine species. Here, we analysed satellite telemetry data foraging preferences in relation to chlorophyll-a productivity fronts understand movements behaviour endangered Mediterranean fin whales ( Balaenoptera physalus) during their spring–summer feeding aggregation North-Western Sea. Eleven individuals were equipped with Argos transmitters across...
ABSTRACT The morphological study of the Odontocete organ Corti, together with possible alterations associated damage from sound exposure, represents a key conservation approach to assess effects acoustic pollution on marine ecosystems. By collaborating stranding networks several European countries, 150 ears 13 species Odontocetes were collected and analyzed by scanning (SEM) transmission (TEM) electron microscopy. Based our analyses, we first describe compare cochlear structures then propose...
The aim of this study was to provide a detailed anatomical description the thoracic region features in normal common (Delphinus delphis) and striped dolphins (Stenella coeruleoalba) compare cross-sections with computed tomography (CT) magnetic resonance imaging (MRI) scans. CT MRI were used scan 7 very fresh by-caught dolphin cadavers: four three dolphins. Diagnostic images obtained from ventral recumbency, after examinations, six frozen (−20°C) sliced same position. As well as scans, body...
Summary The incidence and significance of the appearance various associated congenital malformations in a single individual have received poor attention veterinary medicine. In this article, exhibited by four animals pertaining to three different animal species are described, possible reasons for association these anomalies discussed from viewpoint comparative All showed two or constituting unrecognized teratological syndromes, so‐called one‐of‐a‐kind which not previously been at least...
Computed tomography (CT) and low-field magnetic resonance imaging (MRI) were used to scan seven by-caught dolphin cadavers, belonging two species: four common dolphins (Delphinus delphis) three striped (Stenella coeruleoalba). CT MRI obtained with the animals in ventral recumbency. After procedures, six frozen at −20°C sliced same position they examined. Not only scans, but also cross sections of heads body planes: transverse (slices 1 cm thickness) dolphins, sagittal (5 dorsal dolphins....
Describing the auditory periphery of odontocetes is a key conservation issue to further assess effect acoustic pollution. Because all produce species-specific frequency ranges, differences in echolocation signals should reflect anatomical pathways. Here, we studied ears 15 odontocete species through 3D reconstructions from computerized tomography scans extract standard measurements (bullae lengths/volumes and cochlear volume) investigate discriminatory weight each these variables as well...
The morphology of extracellular matrix (ECM) components and the cell organelles, particularly Golgi complex its derived structures, implicated in production ECM chick embryonic notochord have been studied by transmission electron microscopy. Isolated notochordal fragments were cultured suspension liquid medium. Native striated collagen fibrils with a period 540 Å observed perinotochordal sheath. Fine granular filamentous materials suggestive proteoglycans intercellular spaces under basal...
Summary A newborn diprosopic female calf had a partially duplicated head with two faces each exhibiting mouth, snout, an anomalous incomplete mandible, eyes and lateral ear. single ear small auditory canals was present on the midline between medial eyes. type 1 persistent truncus arteriosus hypoplasia of thoracic portion thymus were most outstanding extracranial defects. In heart, foramen secundum large patent ovale allowed communication right left atria. ventricle, conus separated in part...
