Despite being a leading pollutant in the ocean, there are limited studies about plastic litter in seagrasses, and none has been documented in the Philippines. This study determined the abundance and composition of macroplastics in seagrass beds of Iligan City, Philippines. Plastics were collected from transect lines laid in seagrass beds of four sites (Dalipuga, Hinaplanon, Tominobo and Buru-un), and three locations (landward, midward, seaward) in each site, periodically within 42 days. A total of 921 macroplastic items were collected in all sampling sites, of which 308 were from Buru-un, 271 from Tominobo, 240 from Dalipuga, and 102 from Hinaplanon. Landward areas have a significantly higher density than either midward or seaward. The first sampling was higher than the succeeding sampling period. Food packaging, plastic bags, and fragments predominated the litter in seagrass. This study is the first to document the presence of macroplastics in seagrass beds in the Philippines.

Submerged or partially floating seagrasses in marine or brackish waters form productive seagrass beds, feeding grounds for a rich and varied associated biota, play key ecological roles in mitigating climate change and provide ecosystem services for humanity. The objective of this study was to perform a temporal quali- and quantitative analysis on the scientific production on seagrasses in the Atlantic Ocean during last 64 years (1960 to 2024) through defined workflow by scientometric analysis on Scopus database. Publications in this database date back to 1969, comprising a total of 3.

Seagrass meadows are one of the most productive ecosystems of the world. Seagrass enhances biodiversity, sequesters CO and functions as a coastal protection measure by mitigating waves and enhancing sedimentation. However, populations are declining in many regions and natural recolonization of bare sediment beds is protracted and unlikely.

Metal contamination in seagrass beds has been extensively studied in the past decades. Most of earlier studies have focused on reporting metal concentration in different compartments of seagrass ecosystem, with little attention given to the role of sediment organic matter in controlling the metal mobility and bioavailability. This study investigated metal contamination in seagrass sediments in Hainan Island, China and illustrated how various geochemical factors impact the spatial variability of the metal concentrations.

Coastal ecosystems are increasingly threatened by nutrient imbalances and environmental degradation, which can compromise their stability and productivity. We analyzed the sediment characteristics, microbial community structures, and nutrient cycling across three habitats: mangrove forests, seagrass beds, and bare beaches. The physicochemical properties (including pH, total nitrogen (TN), phosphorus (P), and potassium (K)) of the sediment samples were analyzed, and the microbial diversity was assessed using high-throughput sequencing.
