Blood-based gene expression as non-lethal tool for inferring salinity-habitat history of European eel (Anguilla anguilla)
Bertolini, Francesca; Rohtla, Mehis; Parzanini, Camilla; Tomkiewicz, Jonna; Durif, Caroline (Peer reviewed; Journal article, 2022)The European eel is a facultative catadromous species, meaning that it can skip the freshwater phase or move between marine and freshwater habitats during its continental life stage. Otolith microchemistry, used to determine ... -
Habitat use and growth of yellow-stage European eel in coastal and freshwater ecosystems in Norway
Rohtla, Mehis; Daverat, Françoise; Arts, Michael T.; Browman, Howard; Parzanini, Camilla; Skiftesvik, Anne Berit; Thorstad, Eva Bonsak; van der Meeren, Terje; Vøllestad, Leif Asbjørn; Durif, Caroline (Peer reviewed; Journal article, 2022)Many anguillid eel species display facultative catadromy. Some eel spend their entire life cycle in marine coastal areas, but the geographical extent of this, especially at the extremes of their distributional ranges, is ... -

Overwintering behaviour of yellow-stage European eel (Anguilla anguilla) in a natural marine fjord system
Rohtla, Mehis; Moland, Even; Skiftesvik, Anne Berit; Thorstad, Eva Bonsak; Bosgraaf, Sebastian; Olsen, Esben Moland; Browman, Howard; Durif, Caroline (Peer reviewed; Journal article, 2022)Like many animals, northern temperate eel can enter a hibernation-like state and become dormant during the winter. Knowledge of overwintering behaviour in eel is sparse and mainly based on anecdotal observations and a few ... -
The evolving story of catadromy in the European eel (Anguilla anguilla)
Durif, Caroline; Arts, M.; Bertolini, F.; Cresci, Alessandro; Daverat, F.; Karlsbakk, Egil Erlingsson; Koprivnikar, J.; Moland, Even; Olsen, Esben Moland; Parzanini, C.; Power, M.; Rohtla, Mehis; Skiftesvik, Anne Berit; Thorstad, Eva Bonsak; Vøllestad, Leif Asbjørn; Browman, Howard (Peer reviewed; Journal article, 2023)Anguillid eels were once considered to be the classic example of catadromy. However, alternative life cycles have been reported, including skipping the freshwater phase and habitat shifting between fresh, brackish, and ... -

Trophic ecology of the european eel (Anguilla anguilla) across different salinity habitats inferred from fatty acid and stable isotope analysis
Parzanini, Camilla; Arts, Michael T.; Power, Michael; Rohtla, Mehis; Skiftesvik, Anne Berit; Koprivnikar, Janet; Browman, Howard; Milotic, Dino; Durif, Caroline (Peer reviewed; Journal article, 2021)We combined fatty acid (FA) and stable isotope (SI) analyses to investigate the trophic ecology of different stages of European eels (Anguilla anguilla) across seawater (SW), brackish water (BW), and freshwater (FW) habitats. ...
