Macroalgae influence local and global biogeochemical cycles through their production of dissolved organic carbon (DOC). Yet, data remain scarce annualized estimates are typically based on high growth periods without considering seasonal variability. Although the mechanisms active exudation passive leakage need clarifying, ecophysiological stress is known to enhance DOC release. Therefore, from seasonally senescent macroalgae may be overlooked. This study focuses annual kelp Saccharina japonica var. religiosa (class Phaeophyceae) Oshoro Bay, Hokkaido, Japan. Three years (2020-2022) were collected analyzed, with least squares mean release rates established for (n = 88) across 16 incubation experiments (t ≥ 4 d, samples ≥1 · d

Cold seeps are highly productive chemosynthetic ecosystems in the deep-sea environment. Although microbial communities affected by methane seepage have been extensively studied sediments and seawater, there is a lack of investigation prokaryotic at surface bottom seawater. We revealed effect on co-occurrence networks ecological niches seawater Haima cold seep. The results showed that could cause migration Mn Ba from to overlying altering elemental distribution sites (IS) compared with non-seepage (NS). Principal component analysis (PCA) led closer distances bacterial between Co-occurrence indicated more complex interconnections In summary, caused become abundant structurally complex. This study provides comprehensive comparison profiles South China Sea (SCS), illustrating impact community dynamics.
