The thermal response of soil microbial methanogenesis decreases in magnitude with changing temperature

open access: yesNature Communications, 2020
Soil microbes produce more methane as temperatures warm, but it is unclear if they acclimate to heat, or keep producing more of the greenhouse gas. Here the authors use artificial wetland warming experiments to show that after initial spikes in methane ...

Remote sensing of intertidal morphological change in Morecambe Bay, U.K., between 1991 and 2007 [PDF]

open access: yes, 2010
Tidal Flats are important examples of extensive areas of natural environment that remain relatively unaffected by man. Monitoring of tidal flats is required for a variety of purposes. Remote sensing has become an established technique for the measurement

Diversity, transfer potential, and transcriptional activity of virus‐carried antibiotic resistance genes in global estuaries

open access: yesiMetaOmics, Volume 3, Issue 1, March 2026.
Estuaries are vital hotspots for antibiotic resistance genes (ARGs) due to substantial antibiotic pollution. Although viruses have been proposed as key reservoirs and important disseminators of ARGs in environments, their contribution to the estuarine antibiotic resistome remains largely unknown.

Tropical river discharge dominates riverine carbon export to Australia's coastal waters

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract Rivers play a crucial role in the transformation and export of carbon (C) to coastal waters, yet limited observations in Australia have hindered accurate C flux estimates. We compiled 27,696 dissolved inorganic C (DIC), 15,012 dissolved organic C (DOC), and 226 particulate organic C (POC) measurements in Australian rivers and combined these ...

Anthropogenic interference and climatic change control long‐term dissolved silicate variation in the Yellow River

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract Dissolved silicate (DSi) export from rivers is shaped by both natural processes and human activities. Using long‐term observations at Lijin station combined with chemical weathering and reservoir silicon cycling models, we reconstructed annual DSi fluxes and source‐sink dynamics in the Yellow River Basin since the 1980s.

Towards a comprehensive assessment of ichthyofaunal diversity in the Yangtze River estuary: Leveraging environmental DNA technology and bottom trawl surveys

open access: yesHeliyon
The fishery resources in the Yangtze River Estuary (YRE) have declined drastically because of overfishing and environmental changes, leading to ecosystem degradation of the YRE, and bringing numerous rare fish species to the brink of extinction. As a new

Cyclone‐induced mixing and stratification shape autumnal hypoxia in a temperate estuary

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract Autumnal hypoxia in temperate estuaries is often overlooked due to its smaller extent, weaker intensity, and sparse observations compared to summer. However, climate variability may alter its seasonality. Using 40 yr (1984–2023) of hypoxic volume data from the Chesapeake Bay, combined with numerical simulations, we examined interannual drivers

Study on the distribution and diversity of nanoflagellate in the Yangtze estuary and continental shelf of East China Sea [PDF]

open access: yes, 2015
本研究应用荧光显微技术、荧光标记颗粒示踪法以及Illumina高通量测序技术,分别于2013年春季、2013年夏季和2013年秋季开展了对长江口及东海陆架区微型鞭毛虫的丰度分布、异养细菌的摄食和群落多样性的研究,并初步探讨了影响微型鞭毛虫分布、摄食和群落多样性的因素。主要结果如下: (1)长江口及东海陆架区微型鞭毛虫的丰度变化范围为0.41-7.15×103cellsml-1,微型鞭毛虫丰度的最高值出现在夏季,最低值出现在秋季,表现出明显的季节变化特征 ...

Erosion and Accretion on a Mudflat: The Importance of Very Shallow-Water Effects [PDF]

open access: yes, 2017
Understanding erosion and accretion dynamics during an entire tidal cycle is important for assessing their impacts on the habitats of biological communities and the long‐term morphological evolution of intertidal mudflats. However, previous studies often
