Uncultured Microbial Phyla Suggest Mechanisms for Multi-Thousand-Year Subsistence in Baltic Sea Sediments.

MBio 2019 Apr 16;10(2). Epub 2019 Apr 16.

University of Tennessee, Knoxville, Tennessee, USA

Energy-starved microbes in deep marine sediments subsist at near-zero growth for thousands of years, yet the mechanisms for their subsistence are unknown because no model strains have been cultivated from most of these groups. We investigated Baltic Sea sediments with single-cell genomics, metabolomics, metatranscriptomics, and enzyme assays to identify possible subsistence mechanisms employed by uncultured , , group OPB41, , , , , , and marine group II lineages. Some functions appeared to be shared by multiple lineages, such as trehalose production and NAD-consuming deacetylation, both of which have been shown to increase cellular life spans in other organisms by stabilizing proteins and nucleic acids, respectively.

A Salinity Threshold Separating Fungal Communities in the Baltic Sea.

Front Microbiol 2019 29;10:680. Epub 2019 Mar 29.

Department of Experimental Limnology, Leibniz-Institute of Freshwater Ecology and Inland Fisheries, Stechlin, Germany.

Salinity is a significant factor for structuring microbial communities, but little is known for aquatic fungi, particularly in the pelagic zone of brackish ecosystems. In this study, we explored the diversity and composition of fungal communities following a progressive salinity decline (from 34 to 3 PSU) along three transects of ca. 2000 km in the Baltic Sea, the world's largest estuary.

Dental pulp exposure, periapical inflammation and suppurative osteomyelitis of the jaws in juvenile Baltic grey seals (Halichoerus grypus grypus) from the late 19th century.

PLoS One 2019 12;14(4):e0215401. Epub 2019 Apr 12.

Department of Biology, University of Hildesheim, Hildesheim, Germany.

The systematic analysis of museum collections can provide important insights into the dental and skeletal pathology of wild mammals. Here we present a previously unreported type of dental defect and related skull pathology in five juvenile Baltic grey seals that had been collected in the course of a seal culling program along the Danish coast in 1889 and 1890. All five skulls exhibited openings into the pulp cavities at the crown tips of all (four animals) or two (one animal) canines as well as several incisors and (in one animal) also some anterior premolars.

Genetic analyses reveal complex dynamics within a marine fish management area.

Evol Appl 2019 Apr 20;12(4):830-844. Epub 2019 Jan 20.

National Institute of Aquatic Resources Technical University of Denmark Kgs. Lyngby Denmark.

Genetic data have great potential for improving fisheries management by identifying the fundamental management units-that is, the biological populations-and their mixing. However, so far, the number of practical cases of marine fisheries management using genetics has been limited. Here, we used Atlantic cod in the Baltic Sea to demonstrate the applicability of genetics to a complex management scenario involving mixing of two genetically divergent populations. Read More

Microbial iron metabolism as revealed by gene expression profiles in contrasted Southern Ocean regimes.

Environ Microbiol 2019 Apr 8. Epub 2019 Apr 8.

Sorbonne Université, CNRS, Laboratoire d'Océanographie Microbienne, LOMIC, F-66650 Banyuls/mer, France.

Iron (Fe) is a limiting nutrient in large regions of the ocean, but the strategies of prokaryotes to cope with this micronutrient are poorly known. Using a gene-specific approach from metatranscriptomics data, we investigated 7 Fe-related metabolic pathways in microbial communities from High Nutrient Low Chlorophyll and naturally Fe-fertilized waters in the Southern Ocean. We observed major differences in the contribution of prokaryotic groups at different taxonomic levels to transcripts encoding Fe uptake-mechanisms, intracellular Fe storage and replacement, and Fe-related pathways in the tricarboxylic acid (TCA) cycle.

Do beachrocks affect microplastic deposition on the strandline of sandy beaches?

Mar Pollut Bull 2019 Apr 13;141:569-572. Epub 2019 Mar 13.

Laboratory of Ecology and Management of Estuarine and Coastal Environments, Federal University of Pernambuco (UFPE), Av. Da Arquitetura s/n, 500740-540 Recife, PE, Brazil.

The strandline is one of the first deposition habitats of microplastics before they are integrated to the beach as a standing stock or finally removed. Beaches, entirely or partially protected by beachrocks, have different sediment dynamics and therefore may present variation in microplastic deposition. The aim of this work was to test if protected and unprotected (i. Read More

The Eukaryotic Life on Microplastics in Brackish Ecosystems.

Front Microbiol 2019 20;10:538. Epub 2019 Mar 20.

Department of Experimental Limnology, Leibniz-Institute of Freshwater Ecology and Inland Fisheries, Berlin, Germany.

Microplastics (MP) constitute a widespread contaminant all over the globe. Rivers and wastewater treatment plants (WWTP) transport annually several million tons of MP into freshwaters, estuaries and oceans, where they provide increasing artificial surfaces for microbial colonization. As knowledge on MP-attached communities is insufficient for brackish ecosystems, we conducted exposure experiments in the coastal Baltic Sea, an in-flowing river and a WWTP within the drainage basin.

Classifying grey seal behaviour in relation to environmental variability and commercial fishing activity - a multivariate hidden Markov model.

Sci Rep 2019 Apr 4;9(1):5642. Epub 2019 Apr 4.

Department of Business Administration and Economics, Bielefeld University, Universitätsstraße 25, 33615, Bielefeld, Germany.

Classifying movement behaviour of marine predators in relation to anthropogenic activity and environmental conditions is important to guide marine conservation. We studied the relationship between grey seal (Halichoerus grypus) behaviour and environmental variability in the southwestern Baltic Sea where seal-fishery conflicts are increasing. We used multiple environmental covariates and proximity to active fishing nets within a multivariate hidden Markov model (HMM) to quantify changes in movement behaviour of grey seals while at sea.

A Coupled Global Atmosphere-Ocean Model for Air-Sea Exchange of Mercury: Insights into Wet Deposition and Atmospheric Redox Chemistry.

Environ Sci Technol 2019 Apr 12. Epub 2019 Apr 12.

Department of Environmental Science and Analytical Chemistry , Stockholm University , Stockholm 10691 , Sweden.

Air-sea exchange of mercury (Hg) is the largest flux between Earth system reservoirs. Global models simulate air-sea exchange based either on an atmospheric or ocean model simulation and treat the other media as a boundary condition. Here we develop a new modeling capability (NJUCPL) that couples GEOS-Chem (atmospheric model) and MITgcm (ocean model) at the native hourly model time step. Read More

The status of brown macroalgae Fucus spp. and its relation to environmental variation in the Finnish marine area, northern Baltic Sea.

Ambio 2019 Apr 3. Epub 2019 Apr 3.

Faculty of Science and Engineering, Environmental and Marine Biology, Åbo Akademi University, Tykistökatu 6, 20520, Turku, Finland.

A large-scale loss of the habitat-forming macroalgae Fucus vesiculosus was reported around the Baltic Sea in the 1980's, but only relatively local studies have reported its current status. We studied recent comprehensive mapping data in the Finnish marine area and compared reported Fucus occurrences in relation to its potential, to find out its current status on a larger scale. We also investigated the effects of water quality on Fucus occurrence and its depth penetration. Read More

Experimental evidence of gradual size-dependent shifts in body size and growth of fish in response to warming.

Glob Chang Biol 2019 Apr 1. Epub 2019 Apr 1.

Swedish University of Agricultural Sciences, Department of Aquatic Resources, Skolgatan 6, SE-742 42, Öregrund, Sweden.

A challenge facing ecologists trying to predict responses to climate change is the few recent analogous conditions to use for comparison. For example, negative relationships between ectotherm body size and temperature are common both across natural thermal gradients and in small-scale experiments. However, it is unknown if short-term body size responses are representative of long-term responses. Read More

Cellular and molecular basis of osteoblastic and vascular niches in the processes of hematopoiesis and bone remodeling (A short review of modern views).

Curr Pharm Des 2019 Mar 29. Epub 2019 Mar 29.

Basic Laboratory of Immunology and Cell Biotechnology, Immanuel Kant Baltic Federal University, Kaliningrad. Russian Federation.

In evolutionary processes, human bone marrow has formed as an organ depot of various types of cells that arise from hematopoietic stem cells (HSCs) and mesenchymal stem cells (MSCs). Vital HSC activity is controlled through molecular interactions with the niche microenvironment. The review describes current views on the formation of key molecular and cellular components of the HSC niche, which ensure maintenance of homeostasis in stem cell niches, obtained from studies of their role in regulating the proliferation and differentiation of HSCs, including the physiological, reparative and pathological remodeling of bone tissue.

Shipborne nutrient dynamics and impact on the eutrophication in the Baltic Sea.

Sci Total Environ 2019 Mar 21;671:189-207. Epub 2019 Mar 21.

Swedish Environmental Research Institute, Box 530 21, SE-400 14 Gothenburg, Sweden.

The Baltic Sea is a severely eutrophicated sea-area where intense shipping as an additional nutrient source is a potential contributor to changes in the ecosystem. The impact of the two most important shipborne nutrients, nitrogen and phosphorus, on the overall nutrient-phytoplankton-oxygen dynamics in the Baltic Sea was determined by using the coupled physical and biogeochemical model system General Estuarine Transport Model-Ecological Regional Ocean Model (GETM-ERGOM) in a cascade with the Ship Traffic Emission Assessment Model (STEAM) and the Community Multiscale Air Quality (CMAQ) model. We compared two nutrient scenarios in the Baltic Sea: with (SHIP) and without nutrient input from ships (NOSHIP). Read More

"Cognitive" modes in small networks of almost identical chemical oscillators with pulsatile inhibitory coupling.

Authors:
Vladimir K Vanag

Chaos 2019 Mar;29(3):033106

Centre for Nonlinear Chemistry, Immanuel Kant Baltic Federal University, 14 A. Nevskogo Str., Kaliningrad 236041, Russia.

The Lavrova-Vanag (LV) model of the periodical Belousov-Zhabotinsky (BZ) reaction has been investigated at pulsed self-perturbations, when a sharp spike of the BZ reaction induces a short inhibitory pulse that perturbs the BZ reaction after some time τ since each spike. The dynamics of this BZ system is strongly dependent on the amplitude C of the perturbing pulses. At C > C, a new pseudo-steady state (SS) emerges far away from the limit cycle of the unperturbed BZ oscillator. Read More

Centro de Biología Molecular Severo Ochoa, CSIC-UAM, Madrid, Spain. Electronic address:

An outbreak in the Caucasus in 2007 initiated the spread of ASFV through Russia and Eastern Europe, subsequently affecting Ukraine, Belarus, Poland, the Baltic States, the Czech Republic, Moldova, Romania and Bulgaria. The declaration of outbreaks in China and Central Europe in August 2018, definitely confirms the serious threat that the extension of ASF represents for the global swine industry and the environment. Despite the efforts of several groups to generate a vaccine against ASFV, currently only control and eradication measures are available based mainly on the early detection and implementation of strict sanitary procedures, including the mass slaughter of animals, both domestic and wild boar.

Simulation of Magnetodielectric Effect in Magnetorheological Elastomers.

Int J Mol Sci 2019 Mar 22;20(6). Epub 2019 Mar 22.

Faculty of Physics, Lomonosov Moscow State University, 119991 Moscow, Russia.

We present the results of numerical simulation of magnetodielectric effect (MDE) in magnetorheological elastomers (MRE)-the change of effective permittivity of elastomer placed under the external magnetic field. The computer model of effect is based on an assumption about the displacement of magnetic particles inside the elastic matrix under the external magnetic field and the formation of chain-like structures. Such displacement of metallic particles between the planes of capacitor leads to the change of capacity, which can be considered as a change of effective permittivity of elastomer caused by magnetic field (magnetodielectric effect).

Department of Earth, Environmental and Planetary Sciences, Brown University, Providence, RI, 02912, USA. Electronic address:

Long-chain alkenones (LCAs) and alkenoates (LCEs) are highly valuable biomarkers for paleotemperature reconstructions. A major problem, however, for accurate quantification of these compounds using gas chromatography (GC) is co-elution with steryl ethers, wax esters, saturated ketones and other numerous mid-polarity compounds frequently encountered in marginal marine and lake sediments. Co-elution during GC separation is prevalent, particularly if the full homologous series of alkenones and alkenoates are to be analyzed. Read More

Environmental filtering determines family-level structure of sulfate-reducing microbial communities in subsurface marine sediments.

ISME J 2019 Mar 20. Epub 2019 Mar 20.

Section for Microbiology and Center for Geomicrobiology, Department of Bioscience, Aarhus University, Ny Munkegade 114, Aarhus, 8000, Denmark.

Recent work has shown that subsurface microbial communities assemble by selective survival of surface community members during sediment burial, but it remains unclear to what extent the compositions of the subsurface communities are a product of their founding population at the sediment surface or of the changing geochemical conditions during burial. Here we investigate this question for communities of sulfate-reducing microorganisms (SRMs). We collected marine sediment samples from the upper 3-5 m at four geochemically contrasting sites in the Skagerrak and Baltic Sea and measured SRM abundance (quantitative PCR of dsrB), metabolic activity (radiotracer rate measurements), and community composition (Illumina sequencing of dsrB amplicons).

Seafloor sediments as microplastic sinks in the northern Baltic Sea - Negligible upward transport of buried microplastics by bioturbation.

Environ Pollut 2019 Mar 4;249:74-81. Epub 2019 Mar 4.

Marine Research Centre, Finnish Environment Institute, Latokartanonkaari 11, FI-00790, Helsinki, Finland.

Microplastics (MPs) are ubiquitous in the marine environment. High concentrations of MPs are found from seafloor sediments, which have been proposed to act as their final sinks. Because bioturbation is an important process affecting the burial of MPs, a mesocosm experiment was established to study whether sediment infauna may also promote MP return to the sediment surface.

The relationship between the mtDNA copy number in insulin-dependent tissues and markers of endothelial dysfunction and inflammation in obese patients.

BMC Med Genomics 2019 Mar 13;12(Suppl 2):41. Epub 2019 Mar 13.

Immanuel Kant Baltic Federal University, Russian Federation, Kaliningrad, Gaidara 6 st, Russia.

Background: Mitochondria play a central role in the regulation of energy metabolism, and the biogenesis of mitochondria is enhanced by the action of nitric oxide (NO), which is the key signaling molecule in the regulation of vascular homeostasis. A disturbance in the regulation of energy metabolism can be a key reason for the formation of insulin resistance and type 2 diabetes mellitus. Moreover, mitochondrial dysfunction leads to oxidative stress, which increases the production of proinflammatory cytokines. Read More

Interrelation of chemerin and TNF-α with mtDNA copy number in adipose tissues and blood cells in obese patients with and without type 2 diabetes.

BMC Med Genomics 2019 Mar 13;12(Suppl 2):40. Epub 2019 Mar 13.

Immanuel Kant Baltic Federal University, Russian Federation, Kaliningrad, Gaidara 6 st, Russia.

Background: Inflammatory response plays a key role in the development of insulin resistance (IR) in obesity. Oxidative stress triggers the replication of the mitochondrial genome and division of the organelle. The purpose of this study was to identify the relationship of chemerin and TNF-α with mitochondrial DNA (mtDNA) copy number in subcutaneous adipose tissue (SAT) and visceral adipose tissue (mesentery of the small intestine (Mes), greater omentum (GO) and blood mononuclear cells (MNCs)) in patients with obesity with/without type 2 diabetes mellitus (T2DM).

Toxic effects of chemical warfare agent mixtures on the mussel Mytilus trossulus in the Baltic Sea: A laboratory exposure study.

Mar Environ Res 2019 Mar 7;145:112-122. Epub 2019 Feb 7.

Swedish Defence Research Agency, Cementvägen 20, 90182, Umeå, Sweden.

Baltic blue mussels (Mytilus trossulus) were implemented to assess potential toxicity, health impairments and bioaccumulation of dumped chemical warfare agents on marine benthic organisms. Mussels were collected from a pristine cultivation side and exposed under laboratory conditions to different mixtures of chemical warfare agents (CWAs) related phenyl arsenic compounds, Clark I and Adamsite as well as chloroacetophenone. Using a multi-biomarker approach, mussels were assessed thereafter for effects at different organisational levels ranging from geno-to cytotoxic effects, differences in enzyme kinetics and immunological responses.

Ecological-economic sustainability of the Baltic cod fisheries under ocean warming and acidification.

J Environ Manage 2019 May 5;238:110-118. Epub 2019 Mar 5.

Sustainable Fishery, Department of Economics, Christian-Albrechts-Universität zu Kiel, Kiel, Germany.

Human-induced climate change such as ocean warming and acidification, threatens marine ecosystems and associated fisheries. In the Western Baltic cod stock socio-ecological links are particularly important, with many relying on cod for their livelihoods. A series of recent experiments revealed that cod populations are negatively affected by climate change, but an ecological-economic assessment of the combined effects, and advice on optimal adaptive management are still missing.

Optical Properties of Submillimeter Silver Nanowires Synthesized Using the Hydrothermal Method.

Materials (Basel) 2019 Mar 1;12(5). Epub 2019 Mar 1.

Institute of Physical Chemistry, Polish Academy of Sciences, 01-224 Warsaw, Poland.

We report on the synthesis of long silver nanowires using the hydrothermal method, with H₂O₂ as the reducing agent. Our approach yields nanowires with an average diameter and length of about 100 nm and 160 µm, respectively, reaching the maximum length of 800 µm. Scanning electron microscopy (SEM) measurements revealed the presence of a thick, inhomogeneous poly(vinylpyrrolidone) (PVP) layer covering the nanowires, which with time becomes much more uniform, leading to well-defined extinction peaks in the ultraviolet-visible (UV-Vis) spectra.

Cryptic temporal changes in stock composition explain the decline of a flounder ( spp.) assemblage.

Evol Appl 2019 Mar 21;12(3):549-559. Epub 2019 Jan 21.

Ecological Genetics Research Unit, Research Program in Organismal and Evolutionary Biology University of Helsinki Helsinki Finland.

Unobserved diversity, such as undetected genetic structure or the presence of cryptic species, is of concern for the conservation and management of global biodiversity in the face of threatening anthropogenic processes. For instance, unobserved diversity can lead to overestimation of maximum sustainable yields and therefore to overharvesting of the more vulnerable stock components within unrecognized mixed-stock fisheries. We used DNA from archival (otolith) samples to reconstruct the temporal (1976-2011) genetic makeup of two mixed-stock flounder fisheries in the Åland Sea (AS) and the Gulf of Finland (GoF).

A state-of-the-art model for spatial and stochastic oil spill risk assessment: A case study of oil spill from a shipwreck.

Environ Int 2019 May 27;126:309-320. Epub 2019 Feb 27.

Department of Mechanics and Maritime Sciences, Chalmers University of Technology, SE-41296 Gothenburg, Sweden. Electronic address:

Oil spills are serious environmental issues that potentially can cause adverse effects on marine ecosystems. In some marine areas, like the Baltic Sea, there is a large number of wrecks from the first half of the 20th century, and recent monitoring and field work have revealed release of oil from some of these wrecks. The risk posed by a wreck is governed by its condition, hazardous substances contained in the wreck and the state of the surrounding environment. Read More

Facile Access to Fe(III)-Complexing Cyclic Hydroxamic Acids in a Three-Component Format.

Molecules 2019 Feb 28;24(5). Epub 2019 Feb 28.

Institute of Chemistry, Saint Petersburg State University, 199034 Saint Petersburg, Russia.

Cyclic hydroxamic acids can be viewed as effective binders of soluble iron and can therefore be useful moieties for employing in compounds to treat iron overload disease. Alternatively, they are analogs of bacterial siderophores (iron-scavenging metabolites) and can find utility in designing antibiotic constructs for targeted delivery. An earlier described three-component variant of the Castagnoli-Cushman reaction of homophthalic acid (via in situ cyclodehydration to the respective anhydride) was extended to involve hydroxylamine in lieu of the amine component of the reaction.

Mercury Spikes Indicate a Volcanic Trigger for the Late Ordovician Mass Extinction Event: An Example from a Deep Shelf of the Peri-Baltic Region.

Sci Rep 2019 Feb 28;9(1):3139. Epub 2019 Feb 28.

School of Earth and Environment, University of Leeds, Leeds, LS2 9JT, UK.

The Late Ordovician mass extinction (LOME) was the second largest Phanerozoic crisis, but its cause remains elusive. Several triggering mechanisms have been proposed over the years, including bioevolutionary events, oceanographic changes, and geotectonic processes. Here, we report the presence of Hg spikes in the Zbrza PIG-1 borehole from the Upper Ordovician deep shelf sections of the peri-Baltic region. Read More
