Summary: This study examined the influence of historical and contemporary seagrass variables on sediment organic carbon storage. The results showed that historical seagrass cover, variability in cover, and species diversity were better predictors of storage than environmental variables.

Summary: The spatiotemporal patterns in seagrass-epiphyte dynamics were studied using biomass measurements and scanned-image based metrics to assess the impact of excessive epiphyte accumulations on seagrass condition. Image analysis combined with biomass measures provides enhanced insight into the relationship between seagrass and epiphytes and how it varies with environmental conditions.

Summary: This study investigated the relationship between internal pO(2) of seagrass and H2S and hypoxia in the water column through field experiments. The study found that seagrass has a high capacity for daytime leaf oxidation, which helps to counteract internal hypoxia at night using supersaturated O-2 in the water column. However, shoot meristems of the seagrass still experienced hypoxia at night, even with high daytime irradiance. Furthermore, the study discovered that H2S intrusion into the seagrass occurred when water column pO(2) was close to anoxia.

Summary: Seagrass blade surfaces are rich habitats for microbes, but the primary drivers of composition and structure in these microbial communities are largely unknown. This study found that local environmental conditions can significantly affect the composition of seagrass phyllosphere microbial communities over relatively short time scales. The capacity for these microbial communities to shift dramatically with environmental conditions, including ecosystem perturbations, could significantly impact seagrass-microbe interactions and the health of the seagrass host.

Summary: Grazing pressure is increasing in the northern Gulf of Mexico due to tropicalization and conservation efforts. Understanding mechanisms that promote seagrass resilience to stressors will be crucial for managing and restoring seagrass meadows and the valuable ecosystem services they provide. Our results showed a positive impact of species richness on resilience and indicated that diverse seagrass beds can improve ecosystem stability.

Summary: Understanding how herbivores shape the landscape is important and studying how they incorporate habitat features into their foraging behavior is crucial. However, there is limited knowledge about the influence of habitat structure on megaherbivore grazing in marine ecosystems. In this study, we introduced artificial structures at different scales in a seagrass meadow to investigate the response of green turtles. The results showed that the turtles significantly increased in density and mainly grazed and rested in the areas with structures, resulting in changes in seagrass bed structure and heterogeneity at the landscape scale.

Summary: Assessing the strength of seagrass-grazer links and identifying the mechanisms that regulate these relationships are crucial for understanding community and ecosystem structure and dynamics. Herbivory on temperate seagrass Cymodocea nodosa was evaluated in four locations, showing that between 46.59% and 74.08% of the annual leaf production is lost to herbivory. Herbivory rates increased with higher nitrogen content and shoot density for all types of consumers.

Summary: The presence of the lucinid bivalve enhances the growth and survival of seagrass under decreased light availability and increased sulphide stress, showing a stronger facilitation effect in the presence of environmental stressors. This highlights the potential mechanism by which the association between lucinids and seagrasses is maintained, supporting the incorporation of interspecific facilitation into conservation and restoration strategies for foundation species in the face of global change.

Summary: This study examined the effects of seagrass morphology and leaf nitrogen content on green turtle grazing behavior. The results showed that seagrass morphology significantly affected the forage intake of green turtles, while leaf nitrogen content had no effect. The turtles showed more efficient foraging in areas with shorter leaves and higher leaf biomass concentration. The study also found that the turtles selected shorter leaves for consumption in grazed areas.

Summary: This study investigates the variation of invertebrate communities in seagrass meadows along a phosphorus concentration gradient in five estuarine systems in the Gulf coast of peninsular Florida. The results show that each estuarine system is distinct in terms of species composition, with differences driven by abundant or relatively common species. Furthermore, the study suggests that food webs in seagrass meadows along this gradient may differ, particularly in the relative dominance of algal grazers and predatory invertebrates.

Summary: In vitro and in vivo studies demonstrated the antitumor effects of TTE on colon tumor cell lines and a murine colorectal cancer model, including suppression of cell growth, migration, and angiogenesis, as well as promotion of antitumor immunogenic cell death. Transcription profiling and pathway analysis revealed that TTE triggers specific gene expression and autophagy stress pathways, leading to its antitumor effects.

Summary: This study investigates the use of near-infrared photography to estimate chlorophyll content in seagrass. By measuring the normalized difference vegetation index (NDVI), the study finds a positive correlation between lab-based NDVI and chlorophyll content, as well as an impact of different light conditions on NDVI levels.

Summary: Seagrasses play a crucial role in carbon sequestration and maintaining ecosystem services. The ecological status of seagrass meadows in Indonesia is generally moderate, providing a baseline for conservation efforts and enabling the setting of specific management goals for proactive planning and progress tracking.
