Arsenic speciation in low-trophic marine food chain – An arsenic exposure study on microalgae (Diacronema lutheri) and blue mussels (Mytilus edulis L.)
Tibon, Jojo; Gomez Delgado, Ana Isabel; Aguera, Antonio; Strohmeier, Tore; Silva, Marta Sofia; Lundebye, Anne-Katrine; Larsen, Martin M.; Sloth, Jens Jørgen; Amlund, Heidi; Sele, Veronika (Peer reviewed; Journal article, 2023)Microalgae and blue mussels are known to accumulate undesirable substances from the environment, including arsenic (As). Microalgae can biotransform inorganic As (iAs) to organoarsenic species, which can be transferred to ... -
Fast Changes in the Bioenergetic Balance of Krill in Response to Environmental Stress
Lagos, Paulo F.; Curtsdotter, Alva; Aguera, Antonio; Sabadel, Amandine J. M.; Burrit, David J.; Lamare, Miles D. (Peer reviewed; Journal article, 2022)A Dynamic Energy Budget (DEB) model is applied to predict rapid metabolic shifts in an ecologically important krill, Nyctiphanes australis, in response to temperature and ultraviolet radiation (UVR). Specifically, we predict ... -
High frequency monitoring of feeding activity in benthic suspension feeders
Aguera, Antonio; Strohmeier, Tore; Krogness, Cathinka M.; Strand, Øivind (Peer reviewed; Journal article, 2023)Suspension feeders ecosystem role and services are mainly driven by their efficiency in clearing particles from the water column. As such there is an interest on suspension feeders feeding activity and how they interact ... -
High-Frequency Responses of the Blue Mussel (Mytilus edulis) Feeding and Ingestion Rates to Natural Diets
Steeves, Laura; Aguera, Antonio; Filgueira, Ramón; Strand, Øivind; Strohmeier, Tore (Peer reviewed; Journal article, 2022)The feeding activity of bivalves is understood to change in response to a suite of environmental conditions, including food quantity and quality. It has been hypothesized that, by varying feeding rates in response to the ... -
Life history traits for Ophryotrocha craigsmithi (Wiklund, Glover & Dahlgren, 2009), a candidate species in integrated multitrophic aquaculture
Svensson, Signe Gunborg Bentzröd; Strohmeier, Tore; Rastrick, Helen; Aguera, Antonio; Lock, Erik Jan Robert; Sveier, Harald; Jansen, Henrice M (Peer reviewed; Journal article, 2023)Ophryotrocha craigsmithi (Wiklund, Glover & Dahlgren, 2009) has repeatedly been observed in high densities at salmonid fish farms in Norway and has been shown to feed on the organic waste released during fish production. ... -
Mussel farming production capacity and food web interactions in a mesotrophic environment
Gatti, Paul; Aguera, Antonio; Gao, Shuang; Strand, Øivind; Strohmeier, Tore; Skogen, Morten D. (Peer reviewed; Journal article, 2023)Low trophic aquaculture (LTA), such as bivalve farming, offers promising avenues to supply sustainable seafood and aquafeed. While bivalve farming usually occurs in highly productive coastal areas which already support ... -
Overvåking av blåskjellbestanden – grunnundersøkelse 2021 og 2022
Strohmeier, Tore; Strand, Øivind; Gatti, Paul; Aguera, Antonio (Rapport fra havforskningen;2022 - 38, Research report, 2022)Blåskjell (Mytilus sp.) er utbredt langs hele kysten av Norge. I de siste 15 årene har Havforskningsinstituttet (HI) mottatt meldinger om at blåskjell er blitt borte fra steder hvor det vanligvis sankes skjell. HI utviklet ... -
Seasonal variations in mercury, cadmium, lead and arsenic species in Norwegian blue mussels (Mytilus edulis L.) – Assessing the influence of biological and environmental factors
Gomez Delgado, Ana Isabel; Tibon, Jojo; Silva, Marta Sofia; Lundebye, Anne-Katrine; Aguera, Antonio; Rasinger, Josef; Strohmeier, Tore; Sele, Veronika (Peer reviewed; Journal article, 2023)Blue mussels (Mytilus edulis L.) can accumulate undesirable substances, including the potentially toxic elements (PTEs) cadmium (Cd), mercury, (Hg), lead (Pb), arsenic (As) and As species. In this study, the levels of PTEs ... -
Using correlative and mechanistic niche models to assess the sensitivity of the Antarctic echinoid Sterechinus neumayeri to climate change
Fabri-Ruiz, Salome; Guillaumot, Charlène; Aguera, Antonio; Danis, Bruno; Saucède, Thomas (Peer reviewed; Journal article, 2021)The Southern Ocean is undergoing rapid environmental changes that are likely to have a profound impact on marine life, as organisms are adapted to sub-zero temperatures and display specific adaptations to polar conditions. ...
