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: Tracking the subsea oil plume during the Deepwater Horizon Oil Spill was conducted using both in situ fluorescence and discrete sample chemical analyses. Discrete samples provided a coarse picture of the oil plume footprint, while in situ fluorescence data improved the resolution. Through analysis of millions of continuous data points, fluorescence was found to serve as a proxy for BTEX concentration.

Summary: The Gulf of Mexico Research Initiative (GOMRI) has conducted in-depth studies on the 2010 Deepwater Horizon oil spill from various perspectives and recently assessed the program's accomplishments. By compiling 330 published applications and focusing on modeling efforts, GOMRI has made significant advancements in integrating diverse disciplines and domains. Various modeling tools have been utilized, with a focus on circulation models coupled with other environmental factors to track the fate of oil and its impact on ecosystems and human health.

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 study examines the effectiveness of subsea dispersant injection (SSDI) during the Deepwater Horizon oil spill and evaluates the potential alternatives if dispersants were not used or used more aggressively. The results show that the actual use of SSDI reduced risk to varying degrees, but more effective use of dispersants could have significantly reduced exposures and relative risks across the ecosystem.

Summary: The initial bulk and compound specific composition of the liquid oil spilled during the Deepwater Horizon disaster and the changes in its composition due to weathering are described in this paper. The study highlights the different types of hydrocarbon compounds and their levels of degradation in various environmental compartments.

Summary: This study estimated the age-at-sea of weathered oil slicks using a modeling system and used this information to interpret PAH concentration measurements. The study found that the mean percent depletion of PAHs increased with estimated age-at-sea. Alkylated PAHs showed less depletion compared to parent PAHs.

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: 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 investigated the long-term fate of three groups of petroleum biomarker compounds in Deepwater Horizon (DWH) oil spill residues collected from Alabama beaches over a 10-year period. The results showed that some compounds degraded over time, while others remained recalcitrant. Despite some degradation, the relative diagnostic ratios of the biomarkers remained stable over the 10-year period, providing valuable insights for future studies on the long-term environmental impacts of oil spill residues.

Summary: The 2010 Deepwater Horizon blowout led to an unprecedented recruitment of Gulf menhaden, resulting in increased competition among the fish due to the loss of their predator species. This led to poor physiological conditions and low lipid content, particularly in areas with high recruitment. Trophodynamic comparisons showed the dominant role of Gulf menhaden in the food web, with implications of a trophic cascade and negative impacts on predators. Incorporating such cascading effects in damage assessment models can improve predictions and recovery strategies for major oil spills.

Summary: This study examined the impact of the 2010 Deepwater Horizon oil spill on infaunal community structure in the Chandeleur Islands, Louisiana. The results showed significant differences in the infaunal communities between the moderately oiled site and the lightly oiled site, driven by changes in the abundance of key taxa. The study also observed a decline in most taxonomic and community-level metrics during a re-oiling event, with more pronounced effects in seagrass beds. The study provides important insights into the impact of oil spills on benthic taxa and the potential use of bio-indicators for oil exposure.

Summary: Xanthogranulomatosis is a rare inflammatory lesion in birds, with lipid accumulation, necrosis, fibrosis, and mineralization. This study describes disseminated xanthogranulomatosis in eclectus parrots and budgerigars, presenting with hepatobiliary disease and lipid accumulation in various organs. This condition should be considered as a differential diagnosis in cases of coelomic mass formation and distension in psittacine birds.

Summary: Hepatic lipidosis is a common disease in captive bearded dragons, but there is minimal information available. This study determined the prevalence and risk factors associated with the grade and severity of hepatic lipid changes in bearded dragons submitted for necropsy. The results showed that reproductively active females and adult bearded dragons were more predisposed to hepatic lipid changes, while those with underlying diseases had reduced hepatic lipid accumulation.
