Same same, but different: The response of diatoms to environmental gradients in Fennoscandian streams and lakes – barcodes, traits and microscope data compared
(Peer reviewed; Journal article, 2021)We developed and compared the performance of freshwater benthic diatom indices calculated from (i) traditional morphological species identification, (ii) Amplicon Sequence Variants (ASVs) obtained via DNA metabarcoding, ... -
Sampling and QA/QC: A Guide for Scientists Investigating the Occurrence of Microplastics Across Matrices
(Peer reviewed; Journal article, 2020)Plastic pollution is a defining environmental contaminant and is considered to be one of the greatest environmental threats of the Anthropocene, with its presence documented across aquatic and terrestrial ecosystems. The ... -
Satellite Observations Are Needed to Understand Ocean Acidification and Multi-Stressor Impacts on Fish Stocks in a Changing Arctic Ocean
(Peer reviewed; Journal article, 2021)It is widely projected that under future climate scenarios the economic importance of Arctic Ocean fish stocks will increase. The Arctic Ocean is especially vulnerable to ocean acidification and already experiences low pH ... -
Scenedesmus rubescens Heterotrophic Production Strategies for Added Value Biomass
(Peer reviewed; Journal article, 2023)Microalgae attract interest worldwide due to their potential for several applications. Scenedesmus is one of the first in vitro cultured algae due to their rapid growth and handling easiness. Within this genus, cells exhibit ... -
Scientific Considerations for the Assessment and Management of Mine Tailings Disposal in the Deep Sea
(Journal article; Peer reviewed, 2018)Deep-sea tailings disposal (DSTD) and its shallow water counterpart, submarine tailings disposal (STD), are practiced in many areas of the world, whereby mining industries discharge processed mud- and rock-waste slurries ... -
Scientific rationale and international obligations for protection of active hydrothermal vent ecosystems from deep-sea mining
(Journal article; Peer reviewed, 2018)There is increasing interest in mining minerals on the seabed, including seafloor massive sulfide deposits that form at hydrothermal vents. The International Seabed Authority is currently drafting a Mining Code, including ... -
Screening for Stockholm Convention persistent organic pollutants in the Bosna River (Bosnia and Herzogovina)
(Journal article; Peer reviewed, 2013)The Stockholm Convention, which aspires to manage persistent organic pollutants (POPs) at the international level, was recently ratified in Bosnia and Herzegovina (BiH). Despite this fact, there is in general a paucity of ... -
Screening of Tire-Derived Chemicals and Tire Wear Particles in a Road Tunnel Wash Water Treatment Basin
(Peer reviewed; Journal article, 2023)Road tunnels play a crucial role in modern road networks, in both urban and non-urban areas, and necessitate frequent cleaning and washing due to the harsh tunnel environment. As a result, road tunnels are considered hot ... -
Se-enrichment of Chlorella vulgaris grown under different trophic states for food supplementation
(Peer reviewed; Journal article, 2022)Most European countries, including Portugal, have soils with low selenium (Se) concentrations. This mineral has antioxidant and chemoprotective functions essential for the human immune system. Despite Se being mostly ... -
Seasonal and scale-dependent variability in nutrient- and allelopathy-mediated macrophyte-phytoplankton interactions
(Journal article; Peer reviewed, 2013)macrophyte–phytoplankton interactions were investigated using a dual laboratory and field approach during a growing season, with responses quantified as changes in biomass. Short-term, close-range interactions in laboratory ... -
Seasonal and spatial variations in biomarker baseline levels within Arctic populations of mussels (Mytilus spp.)
(Journal article; Peer reviewed, 2019)Climate change and pollution resulting from human activities in the Arctic require reliable monitoring systems in sentinel species. Mytilus spp. are used as sentinel species all around the world. The use of Mytilus spp. ... -
Seasonal and year-to-year variation of mercury concentration in perch (Perca fluviatilis) in boreal lakes
(Journal article; Peer reviewed, 2014)The authors examined the seasonal and year‐to‐year variations of mercury (Hg) concentrations in populations of perch (Perca fluviatilis) from 2 boreal freshwater lakes in southeast Norway. Fish Hg concentrations were ... -
Seasonal diversity and dynamics of haptophytes in the Skagerrak, Norway, explored by high-throughput sequencing
(Journal article, 2015)Microalgae in the division Haptophyta play key roles in the marine ecosystem and in global biogeochemical processes. Despite their ecological importance, knowledge on seasonal dynamics, community composition and abundance ... -
Seasonal forecasting of lake water quality and algal bloom risk using a continuous Gaussian Bayesian network
(Peer reviewed; Journal article, 2022)Freshwater management is challenging, and advance warning that poor water quality was likely, a season ahead, could allow for preventative measures to be put in place. To this end, we developed a Bayesian network (BN) for ... -
Seasonal pollutant levels in littoral high-Arctic amphipods in relation to food sources and terrestrial run-off
(Peer reviewed; Journal article, 2022)Increasing terrestrial run-off from melting glaciers and thawing permafrost to Arctic coastal areas is expected to facilitate re-mobilization of stored legacy persistent organic pollutants (POPs) and mercury (Hg), potentially ... -
Seasonal rainfall affects occurrence of organohalogen contaminants in tropical marine fishes and prawns from Zanzibar, Tanzania
(Peer reviewed; Journal article, 2021)Seasonal differences in precipitation may affect contaminant dynamics in tropical coastal regions due to terrestrial runoff of contaminants to the marine environment after the rainy seasons. To assess the effect of seasonal ... -
Seasonal riverine inputs may affect diet and mercury bioaccumulation in Arctic coastal zooplankton
(Peer reviewed; Journal article, 2023)Climate change driven increases in permafrost thaw and terrestrial runoff are expected to facilitate the mobilization and transport of mercury (Hg) from catchment soils to coastal areas in the Arctic, potentially increasing ... -
Seasonal turnover in community composition of stream-associated macroinvertebrates inferred from freshwater environmental DNA metabarcoding
(Peer reviewed; Journal article, 2021)Macroinvertebrate communities are crucial for biodiversity monitoring and assessment of ecological status in stream ecosystems. However, traditional monitoring approaches require intensive sampling and rely on invasive ... -
