Department of Bioscience, University of Oslo, Blindernveien 31, 0371 Oslo, Norway. Electronic address:

Increases in terrestrial organic matter (tOM) transport from catchments to boreal lakes can affect methylmercury (MeHg) accumulation in aquatic biota both directly by increasing concentrations of aqueous MeHg, and indirectly through effects on MeHg bioavailability and on energy pathways in the lower food web. We carried out a detailed seasonal study of water chemistry, zooplankton diet, and MeHg accumulation in zooplankton in two lakes with contrasting tOM concentrations. Between-lake differences explained 51% of the variability in our water chemistry data, with no observed effect of season or sampling depth, contrary to our expectations. Read More

How closely do mercury trends in fish and other aquatic wildlife track those in the atmosphere? - Implications for evaluating the effectiveness of the Minamata Convention.

Sci Total Environ 2019 Apr 9;674:58-70. Epub 2019 Apr 9.

Department of Marine Sciences, University of Connecticut, 1080 Shennecossett Road, Groton, CT 06340, USA.

The Minamata Convention to reduce anthropogenic mercury (Hg) emissions entered into force in 2017, and attention is now focused on how to best monitor its effectiveness at reducing Hg exposure to humans. A key question is how closely Hg concentrations in the human food chain, especially in fish and other aquatic wildlife, will track the changes in atmospheric Hg that are expected to occur following anthropogenic emission reductions. We investigated this question by evaluating several regional groups of case studies where Hg concentrations in aquatic biota have been monitored continuously or intermittently for several decades.

Mixotrophic trade-off under warming and UVR in a marine and a freshwater alga.

J Phycol 2019 Apr 18. Epub 2019 Apr 18.

University Institute of Water research, University of Granada, C/Ramón y Cajal, 4, Granada, 18071, Spain.

Mixotrophic protists combine phagotrophy and phototrophy within a single cell. Greater phagotrophic activity could reinforce the bypass of carbon (C) flux through the bacteria-mixotroph link and thus lead to a more efficient transfer of C and other nutrients to the top of the trophic web. To determine whether foreseeable changes in temperature and UVR upset the mixotrophic trade-off in favor of one or the other nutritional strategy along the mixotrophic gradient is key to understanding the fate of C and mineral nutrients in the aquatic ecosystem.

Precipitation and temperature drive continental-scale patterns in stream invertebrate production.

Sci Adv 2019 Apr 17;5(4):eaav2348. Epub 2019 Apr 17.

Department of Life Sciences, Imperial College London, Silwood Park Campus, Buckhurst Rd., Ascot, Berkshire SL5 7PY, UK.

Secondary production, the growth of new heterotrophic biomass, is a key process in aquatic and terrestrial ecosystems that has been carefully measured in many flowing water ecosystems. We combine structural equation modeling with the first worldwide dataset on annual secondary production of stream invertebrate communities to reveal core pathways linking air temperature and precipitation to secondary production. In the United States, where the most extensive set of secondary production estimates and covariate data were available, we show that precipitation-mediated, low-stream flow events have a strong negative effect on secondary production.

Accuracy assessment of NLCD 2011 impervious cover data for the Chesapeake Bay region, USA.

ISPRS J Photogramm Remote Sens 2018 ;146:151-160

U.S. Geological Survey (USGS), Chesapeake Bay Program Office, 410 Severn Ave., Annapolis, MD 21043, United States.

The National Land Cover Database (NLCD) contains three eras (2001, 2006, 2011) of percentage urban impervious cover (%IC) at the native pixel size (30 m-×-30 m) of the Landsat Thematic Mapper satellite. These data are potentially valuable to environmental managers and stakeholders because of the utility of %IC as an indicator of watershed and aquatic condition, but lack an accuracy assessment because of the absence of suitable reference data. Recently developed 1 m land cover data for the Chesapeake Bay region makes it possible to assess NLCD %IC accuracy for a 262,000 km region based on a census rather than a sample of reference data.

Arrowhead () as a bioindicator of nitrogen and phosphorus for prairie streams and wetlands.

Wetl Ecol Manag 2018 27;26(3):331-343. Epub 2017 Sep 27.

1Biology Department and Canadian Rivers Institute, University of New Brunswick, PO Box 4400, Fredericton, NB E3B 5A3 Canada.

The emergent aquatic plant, is an easily-identified and commonly-found species in the Great Plains region of North America and has the potential to be a bioindicator of nitrogen (N) and phosphorus (P) because of its previously-identified leaf plasticity in response to nutrient conditions. To identify associations between leaf morphology and soil and water nutrients, we conducted: (1) a 10-week controlled experiment in which plants were grown in nutrient-enriched sediment, nutrient-enriched water, or unamended control trials, and (2) a field study where emergent leaves were collected from 15 streams of varying nutrient concentrations. Plants grown in experimentally enriched sediment were more productive than those grown in enriched water or control conditions: they produced more emergent leaves and tubers, had a larger final biomass and height, and developed emergent leaves that showed a consistent increase in size and unique change in shape over time.

Identification and expression of microRNAs in european eels Anguilla anguilla from two natural sites with different pollution levels.

Environ Pollut 2019 Apr 11;250:274-283. Epub 2019 Apr 11.

Univ. Bordeaux, UMR EPOC CNRS 5805, 33615, Pessac, France.

MicroRNAs (miRNAs) are a class of small non-coding RNA that control multiple biological processes through negative post-transcriptional regulation of gene expression. Recently a role of miRNAs in the response of aquatic organisms to environmental toxicants emerged. Toxicant-induced changes in miRNA expression might then represent novel biomarkers to evaluate the health status of these organisms. Read More

A re-evaluation of chironomid deformities as an environmental stress response: avoiding survivorship bias and testing noncontaminant biological factors.

Environ Toxicol Chem 2019 Apr 18. Epub 2019 Apr 18.

School of BioSciences, University of Melbourne, VIC, Australia.

Larval deformities have been observed in chironomids, and are thought to be associated with aquatic contaminant exposure. However, deformities have not been linked with contaminants in the absence of potential confounding variables including mortality in laboratory assays, which introduces a survivorship bias (SB). There is also a paucity of data on noncontaminant causes. Read More

Aquatic EcoHealth Group, Key Laboratory of Urban Environment and Health, Institute of Urban Environment, Chinese Academy of Sciences, Xiamen 361021, China. Electronic address:

Although seasonality is a key driver of environmental fluctuation in aquatic ecosystems, there exists limited knowledge on the factors controlling the distribution of antibiotic resistance genes (ARGs) across seasons at a watershed scale. Here we used high-throughput quantitative PCR to quantify 285 ARGs conferring resistance to most major classes of antibiotics, reveal their spatial and seasonal distribution patterns, and depict the underlying mechanisms in a subtropical riverine ecosystem under low and high human pressures, in Xiamen city, southeast China. Our results showed that spatial differences in ARG richness and abundance overwhelmed their seasonal variations, with only ARGs that confer resistance to sulfonamide and vancomycin being significantly different across seasons.
