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: Marine biofilms play a crucial role in transforming built structures into artificial reefs, but anthropogenic contaminants like crude oil and dispersant can disrupt their diversity and function. Metagenomic analysis of biofilms from different marine environments revealed taxonomic differences and higher diversity in surface seawater biofilms. Functional differences between surface and deep seawater biofilms were primarily driven by membrane transport genes, while similarities were observed in translation, signaling, and cellular process genes. Oil and dispersant exposure led to functional redundancy in microbiomes, highlighting the importance of considering microbial composition and function when studying responses to environmental changes in marine biofilms.

Summary: Tidal wetlands are important reservoirs of soil organic carbon, and remote sensing studies can help estimate and map these carbon stocks. However, most remote sensing studies have focused on upland ecosystems rather than tidal wetlands. This comprehensive review highlights the need for further research on tidal wetland soil organic carbon and proposes new methods, such as machine learning models, to improve predictions. Preliminary results suggest a significant relationship between surface and subsurface soil organic carbon. The study also suggests considering additional covariates specific to tidal wetlands, such as tidal inundation frequency and vegetation species.

Summary: The IPCC Special Report on the Ocean and Cryosphere in a Changing Climate emphasizes the significance of blue carbon in tidal wetlands for combatting climate change. This study focuses on the uncertainty surrounding leaf area index (LAI) estimations in tidal wetlands, particularly salt marshes, which is a crucial vegetation parameter for productivity and Earth System Models (ESMs). The research presents a novel approach for measuring spatiotemporal dynamics in tidal wetland emergent leaf area index (ELAI) and demonstrates the correlations between ELAI and carbon fluxes. The study also highlights the feasibility of estimating ELAI using Sentinel-2 satellite data and addresses the underestimation and overestimation of LAI by a commonly used product, MODIS MYD15A2H.
