Studies of marine benthic archaeal communities are updating our view their taxonomic composition and metabolic versatility. However, large knowledge gaps remain with regard to community assembly processes inter taxa associations. Here, using 16S rRNA gene amplicon sequencing qPCR, we investigated the spatiotemporal dynamics, processes, co-occurrence relationships in 58 surface sediment samples collected both summer winter from across ~1500 km eastern Chinese marginal seas. Clear patterns dynamics structure were observed, a more pronounced spatial rather than seasonal variation. Accompanying geographic variation was significant distance-decay pattern varying contributions different clades, determined by relative abundance. In seasons, dispersal limitation most important process, explaining ~40% variation, followed homogeneous selection ecological drift, that made an approximately equal contribution (~30%). This meant stochasticity determinism had greater impact on assembly. Furthermore, observed seasonality patterns: closer inter-taxa connections summer, unmatched between relationship. These results demonstrate assembled under seasonal-consistent mechanism but changed over indicating complex dynamic coastal sediments

Comparing Subsurface Seasonal Deoxygenation and Acidification in the Yellow Sea and Northern East China Sea Along the North-to-South Latitude Gradient

Frontiers in Marine Science, Год журнала: 2020, Номер 7

To better understand the relationship between subsurface seasonal deoxygenation and acidification in Yellow Sea northern East China (ECS), we examined carbonate system parameters dissolved oxygen (DO) of seven field surveys conducted 2017–2018, spanning all four seasons. Low pHT values 7.71‒7.80 critically low aragonite saturation state (Ωarag) 1.07‒1.40 along with undersaturated DO mostly higher than 150 μmol O2 kg–1 occurred Cold Water Mass area summer autumn, while hypoxic 49‒63 extremely 7.68‒7.74 as well Ωarag 1.21‒1.39 were observed ECS July 2018. At beginning warm-season stratification formation, cold waters had much but lower those relatively warmer waters, yearly initial rarely exhibited differences two coastal seas. During warm seasons, central accumulated respiration products beneath thermocline bottom preserved them only summer. This study highlights fundamental roles wintertime carbon dioxide (CO2) solubility a north-to-south latitude gradient development. In comparison low-latitude subject to hypoxia, high-latitude exhibits CO2 winter longer respiration-product accumulations leading ECS. However, present-day is free from hypoxia.
