Summary: This study found that blood gas analysis and capnography can be used to evaluate the oxygenation status in dolphins with and without pulmonary disease. Dolphins with moderate-severe lung disease had higher concentrations of bicarbonate, pH, TCO2, and base excess compared to dolphins with normal-mild disease. Capnography showed a weak positive correlation with blood PCO2. These findings suggest that indirect oxygenation measures, including TCO2, bicarbonate, and pH, show promise in assessing the oxygenation status in dolphins.

Summary: The Deepwater Horizon oil spill was the largest and deepest oil accident in US waters, with significant impacts on the marine ecosystem. The released oil underwent various mechanisms, including biodegradation, to transform and disperse, with some sedimenting onto the seafloor. Further research efforts have greatly increased our understanding of the fate of spilled oil, focusing on factors such as photooxidation, microbial communities, and marine oil snow formation.

Summary: This article expands the current knowledge of interfacial phenomena related to chemical dispersants application in oil spills, focusing on a representative Brazilian crude oil. By evaluating the dispersion effectiveness of different oil samples under various conditions, including water salinity and dispersant concentration, the study sheds light on the interfacial behavior of this specific oil-water system.

Summary: The Deepwater Horizon disaster had a significant impact on the lung health of common bottlenose dolphins in the northern Gulf of Mexico. The dolphins living within the oil spill footprint showed a higher prevalence of moderate to severe lung disease compared to the dolphins in the uncontaminated area. The presence of lung disease remained persistent and potentially worsened over the years after the spill.

Summary: This study aimed to quantitatively determine the toxicity of oil remaining in sediment from the Deepwater Horizon oil spill, and found that less than 13% of toxicity tests on benthic species showed toxicity. There was no clear relationship between toxicity test results, oiling category, or measured total polycyclic aromatic hydrocarbons (PAHs).

Summary: Exposure to crude oil can cause various pathological effects in birds, but not all species develop Heinz bodies or anemia. In a study on zebra finches, high doses of oil led to increased reticulocyte percentage and mean corpuscular hemoglobin concentration, as well as inflammation and lymphocyte proliferation, but no Heinz bodies were found. Further research is needed to understand factors contributing to anemia resulting from oil exposure in birds.

Summary: Dolphins use various techniques to detect and capture prey, including a previously undescribed behavior called "drill feeding". They can hunt independently or in groups, and exhibit different hunting techniques and cooperative interactions with other species.

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 study identified significant cardiac abnormalities in bottlenose dolphins in Barataria Bay impacted by the Deepwater Horizon oil spill, potentially linked to oil exposure. Further research is needed to confirm this association and rule out alternative hypotheses.

Summary: Health assessments on bottlenose dolphins in Barataria Bay and Sarasota Bay revealed potential immunological effects of the Deepwater Horizon oil spill, including changes in T-cell proliferation and cytokine balance. Further studies suggest Treg cells as a potential target for the immunomodulatory effects of oil exposure, with possible multigenerational health consequences observed in dolphins born after the spill.

Summary: This study aims to understand the social and genetic structure of common bottlenose dolphins in the Barataria Bay Estuarine System. Through photo-identification data analysis and genetic analyses, four distinct social clusters and three genetic clusters were identified. The dolphins in the Barataria Basin were found to be genetically different from those in adjacent coastal waters.

Summary: The largest unusual mortality event of cetaceans recorded in the Gulf of Mexico occurred from 2010 to 2014, with the majority of deaths being Common Bottlenose Dolphins near Barataria Bay, Louisiana. The study identified the diet of dolphins in the area, revealing that their main prey was the Atlantic Croaker and that they foraged along the bottom of the bay, potentially leading to long-term oil exposure.

Summary: This study aimed to assess the relationship between exposure to the 2010 Deepwater Horizon oil spill and parents' self-rated health over time. The results showed that both physical and economic exposure to the oil spill had negative associations with self-rated health, with physical exposure having a larger effect size.

Summary: When oil is spilled into the environment, its toxicity is influenced by abiotic conditions and multiple stressors. Changes in oil toxicity occur with different temperatures, salinities, and UV light exposure.

Summary: The explosion of the Deepwater Horizon drilling unit on April 20, 2010 led to a massive oil spill in the Gulf of Mexico, which was subsequently cleaned up using chemical dispersants. The study investigated the exposure of workers to these dispersants, with results indicating that exposure to 2-BE may have exceeded limits for peak exposures in certain conditions.

Summary: Environmental changes and commercial whaling have significantly reduced whale populations, including gray whales in the North Pacific. However, genetic signals of recent population declines have not been detected despite sustained habitat loss and a commercial whaling bottleneck. Large haplotype sharing between gray whales in Russian and Mexican waters suggests limited population structure.
