Top-down release of mesopredatory fish is a weaker structuring driver of temperate rocky shore communities than bottom-up nutrient enrichment
(Peer reviewed; Journal article, 2020)Ecological impacts of top-down trophic cascades in combination with bottom-up nutrient enrichment are increasingly being reported. Such effects may be triggered by decline in the abundance and size of piscivore fish leading ... -
Top-down versus bottom-up project appraisal processes, and external review. Evidence from Norway and China
(Peer reviewed; Journal article, 2013)Project appraisal plays an important role in choosing the right project and is crucial for the success of public investment projects. Different factors may affect the choice of appraisal process in different countries. By ... -
Towards a comprehensive and realistic risk evaluation of engineered nanomaterials in the urban water cycle
(Journal article; Peer reviewed, 2014) -
Towards a future without stocking: harvest and river regulation determine long-term population viability of migratory salmonids
(Peer reviewed; Journal article, 2021)Freshwater species are particularly vulnerable to emerging threats linked to climate change because they are often already heavily impacted by habitat destruction, pollution, and exploitation. For many harvested populations ... -
Towards sustainable management of kelp forests: An analysis of adaptive governance in developing regimes for wild kelp harvesting in Scotland and Norway
(Peer reviewed; Journal article, 2021)Kelp forests are highly productive habitats which support important marine species and ecosystem services including coastal protection and carbon storage. Demand is increasing for commercial products from wild and cultivated ... -
Toxicity of microplastics and natural particles in the freshwater dipteran Chironomus riparius: Same same but different?
(Peer reviewed; Journal article, 2020)Microplastics (MP) are contaminants of emerging concern in aquatic ecosystems. While the number of studies is rapidly increasing, a comparison of the toxicity of MP and natural particulate matter is largely missing. In ... -
Toxicity of organic compounds from unresolved complex mixtures (UCMs) to primary fish hepatocytes
(Journal article; Peer reviewed, 2017)Many environmental matrices contaminated with organic pollutants derived from crude oil or degraded petroleum contain mixtures so complex that they are typically unresolved by conventional analytical techniques such as gas ... -
Traditional Dimensions of Seabed Resource Management in the Context of Deep Sea Mining in the Pacific: Learning From the Socio-Ecological Interconnectivity Between Island Communities and the Ocean Realm
(Peer reviewed; Journal article, 2021)In many of the Pacific Islands, local communities have long-held cultural and spiritual attachments to the sea, in particular to species and specific marine areas, processes, habitats, islands, and natural seabed formations. ... -
Trait‐based ecology at large scales: Assessing functional trait correlations, phylogenetic constraints and spatial variability using open data
(Peer reviewed; Journal article, 2020)The growing use of functional traits in ecological research has brought new insights into biodiversity responses to global environmental change. However, further progress depends on overcoming three major challenges involving ... -
Transcriptional changes in Atlantic salmon (Salmo salar) after embryonic exposure to road salt
(Journal article; Peer reviewed, 2015)Road salt is extensively used as a deicing chemical in road maintenance during winter and has in certain areas of the world led to density stratifications in lakes and ponds, and adversely impacted aquatic organisms in the ... -
Transcriptomic analysis reveals dose-dependent modes of action of benzo(a)pyrene in polar cod (Boreogadus saida)
(Journal article; Peer reviewed, 2019)Polar cod (Boreogadus saida) has been used as a model Arctic species for hazard assessment of environmental stressors such as polycyclic aromatic hydrocarbons (PAHs). However, most of the PAH studies using polar cod rely ... -
Transfer and transport of microplastics from biosolids to agricultural soils and the wider environment
(Peer reviewed; Journal article, 2020)Between April to November of 2017, microplastics (MPs) were analysed in biosolids from two separate suppliers, and in the soils of three agricultural fields to which they were applied, in Ontario, Canada. Soils of a control ... -
Transformation as praxis: responding to climate change uncertainties in marginal environments in South Asia
(Peer reviewed; Journal article, 2021)This paper provides some of the conceptual and methodological underpinnings being developed in the ongoing TAPESTRY project which is part of the Transformations to Sustainability (T2S) Programme. We debate how the notion ... -
Transformation Kinetics of Burnt Lime in Freshwater and Sea Water
(Peer reviewed; Journal article, 2020)Calcium oxide (CaO), also known as burnt lime, is being considered as a possible treatment to reduce the negative impact of sea urchins on tare forests in northern coastal waters and blue-green algal blooms in the surrounding ... -
Transgenic (cyp19a1b-GFP) zebrafish embryos as a tool for assessing combined effects of oestrogenic chemicals
(Journal article; Peer reviewed, 2013)Endocrine disrupting chemicals and especially oestrogen receptor (ER) agonists have been extensively studied over the years due to their potential effects on sexual development and reproduction in vertebrates, notably fish. ... -
Trends and potential human health risk of trace elements accumulated in transplanted blue mussels during restoration activities of Flekkefjord fjord (Southern Norway)
(Peer reviewed; Journal article, 2022)The monitoring of contaminants represents a priority to preserve the integrity of marine ecosystems, as well as to plan and to manage restoration activities in order to protect environmental and human health. In the present ... -
Trends in surface water chemistry in acidified areas in Europe and North America from 1990 to 2008
(Journal article; Peer reviewed, 2014)Acidification of lakes and rivers is still an environmental concern despite reduced emissions of acidifying compounds. We analysed trends in surface water chemistry of 173 acid-sensitive sites from 12 regions in Europe and ... -
Tryptophan metabolic pathways and brain serotonergic activity: A comparative review
(Journal article; Peer reviewed, 2019)The essential amino acid L-tryptophan (Trp) is the precursor of the monoaminergic neurotransmitter serotonin (5-hydroxytryptamine, 5-HT). Numerous studies have shown that elevated dietary Trp has a suppressive effect on ... -
Two different approaches of microbial community structure characterization in riverine epilithic biofilms under multiple stressors conditions: Developing molecular indicators
