Summary: This study describes an assemblage of late Valanginian spicules from NE Sardinia, comprising 21 taxa within two classes, Demospongiae and Hexactinellida. The fauna, associated with abundant radiolarians, includes morphotypes that have no modern counterparts and spicules identical to those in modern species. The fossil record suggests that most of the observed morphotypes date back to the Jurassic or Triassic. The presence of spicules from both shallow-water and deep-water sponges indicates that this Early Cretaceous assemblage lived at depths around 200 m.

Summary: A study conducted on common bottlenose dolphins in Barataria Bay, Louisiana, revealed that dolphins do not significantly change their movements in response to fluctuations in salinity, but health issues such as skin lesions and abnormalities in biochemical markers were observed in lower salinity areas.

Summary: The Agoa protected marine area in the French West Indies is an important habitat for the pantropical spotted dolphin. A photo-identification study was conducted over a period of five years, using a large collection of photos to identify individuals. The study revealed differences in residency clusters and population sizes between Guadeloupe and Martinique.

Summary: This study identifies a residential group of coastal bottlenose dolphins in the northwestern Atlantic waters off the coast of Palm Beach County, Florida. The presence of individuals with high site fidelity indicates that the region is used as a permanent habitat for some individuals, while the presence of transient animals may indicate a possible bridge between populations living to the north and south of the region.

Summary: This study evaluated the site fidelity of common bottlenose dolphins in upper Galveston Bay. Through photo-identification surveys, three groups were identified, with one group being resident dolphins in UGB. This study is important for the conservation of these populations and monitoring potential stressors.

Summary: Obtaining sufficient data on ranging patterns and space use is challenging for long-lived species like marine mammals. This study combined data from multiple sources to assess the ranging patterns and site fidelity of Australian snubfin dolphins in Yawuru Nagulagun/Roebuck Bay. The results highlight the importance of this area for the conservation of the species and emphasize the need to consider human activities and coastal development in management efforts.

Summary: The social structure of estuarine-resident bottlenose dolphins in North Carolina is complex and not consistent with current stock designations. A new capture-mark-recapture survey in 2018 identified a higher abundance estimate compared to previous estimates. Social network analysis revealed three primary clusters that were not defined by spatiotemporal distribution.

Summary: Aquaculture is an important source of food and contributes to economic development. Offshore farming has advantages in terms of lower production costs and higher product quality. However, suitable areas for aquaculture in Italy are limited and face complex regulatory constraints. The process of zoning can help identify and allocate suitable areas for sustainable aquaculture.

Summary: This article presents a case history of an abandoned waste disposal site near Sardinia, Italy. The researchers conducted a frequency-domain electromagnetic survey to detect buried waste and delineate the extent of the landfill. Through data processing, they obtained high-resolution maps that correlated well with other geophysical methods and ground truthing data.

Summary: This study provides the first description of occurrence and demographic parameters for the community of common bottlenose dolphins inhabiting waters of North Dalmatia. The estimated abundance varied annually with no significant trend confirmed. Site-fidelity analysis revealed that 52.1% of encountered marked adults occur in the area regularly or occasionally.

Summary: The study on coastal bottlenose dolphins in Roanoke Sound, North Carolina, showed that skin lesions can indicate population health, with little variation in lesion prevalence between years. Most lesions occurred in the spring, with pale lesions being the most common type. Annual lesion prevalence estimates were comparable to other locations, but seasonal differences in lesion occurrence and type were observed. Future research should focus on relationships between lesions and environmental variables.

Summary: This study analyzed the mercury and selenium concentrations in bottlenose, striped, and Risso's dolphins stranded in the Croatian part of the Adriatic Sea. The results showed that Risso's dolphins had higher levels of mercury and selenium in all tissues compared to bottlenose and striped dolphins. Age was positively correlated with mercury concentrations. Liver damage was observed in some Risso's and bottlenose dolphins due to high mercury levels in their tissues.

Summary: This study used optical microscopy, micro-Raman spectroscopy, X-ray diffractometry, and scanning electron microscopy to analyze the corrosion patina on nine coins found underwater. Three main types of corrosion patina based on copper, lead chloride, and carbonate were identified: black, white, and green. The results demonstrate the complex corrosion processes that occur underwater. The study attempts to understand the nature of the patinas on the coins in relation to specific structural and environmental parameter variation.

Summary: This study highlights the spatial segregation between common dolphins and bottlenose dolphins in the Ria de Arousa, Northwest Spain, and documents the first direct observation of interspecific killing and necrophilia in cetaceans. While both species use the area as a foraging ground, they have different patterns of occurrence and only interacted on a few occasions, one of which led to a lethal interaction. Further research on such behaviors and their implications would be crucial for understanding the dynamics between these two species.

Summary: The expansion and increased efficiency of fisheries have severe detrimental impacts on marine species and ecosystems, especially top predators. The use of Ecopath with Ecosim provides a useful tool to develop more holistic fisheries management and conservation strategies, playing a key role in cetacean conservation.

Summary: The study in the Arabian Gulf found that the Indo-Pacific bottlenose dolphin has strong adaptability to extreme environmental conditions and prefers less human-impacted areas, providing the first abundance estimates for this population. The results support the call for increased marine-protected areas and the creation of transboundary conservation areas in the region.

Summary: This study addresses the lack of information on marine mammal diversity, distribution, and density in the Saudi waters of the Arabian Gulf. The research confirms a high diversity of cetaceans in the region, with bottlenose and humpback dolphins being the most common species, while Dugongs are mainly found in coastal waters in the southern part of the study area. The presence of dolphins is increased during the summer months and in the vicinity of oil and gas facilities, mainly within a 10-20 km radius around each facility.
