Frame Transplantation System (FTS) is considered an efficient method for seagrass restoration, but the effect of the rusting of iron frame on seagrass restoration remains unclear. We transplanted Zostera marina plants using iron FTS treated with fluorocarbon paint (painted treatment, PT) and traditional unpainted iron FTS (unpainted treatment, UT) under controlled mesocosm conditions for 24 days. Our results showed that the survival rate of Z. marina under the UT was significantly 31.2 % lower than that of the plants under the PT. Soluble sugar content in Z. marina rhizomes under the UT was significantly 2.19 times higher than that of the plants under the PT. Transcriptome analysis revealed differentially expressed genes (DEGs) involved in photosynthesis, metabolism and signal transduction functions. The results provide valuable data that could prove helpful in the development of efficient restoration techniques for Z. marina beds.

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.

Seagrass meadows are acknowledged as blue carbon ecosystems, yet they are also ideal habitats for methane (CH) release, offsetting their ability to mitigate climate change. The global CH fluxes in seagrass meadows remain highly uncertain due to regional and species biases, and the microbial mechanisms driving methane release are poorly understood. Here, we investigated CH air-sea fluxes, sediment CH emission potential and microbes involved in CH release using geochemical techniques combined with qPCR and Illumina sequencing in a temperate Zostera japonica and Zostera marina mixed meadow.

Coastal marine macrophytes are critical ecosystem engineers providing valuable ecosystem services. However, they experience detrimental impacts from climate change-induced stresses such as marine heatwaves (MHW), which are becoming more intense and frequent. This study investigated trait responses in real-term heatwaves, Continuous (1MHW) and Consecutive (with a 4-day lag phase, 2MHW), on two key macrophytes, the seaweed Fucus vesiculosus and seagrass Zostera marina.
