Aquaculture rearing systems induce no legacy effects in Atlantic cod larvae or their rearing water bacterial communities
Gundersen, Madeleine S.; Vadstein, Olav; De Schryver, Peter; Attramadal, Kari (Peer reviewed; Journal article, 2022)The microbial rearing quality influences the survival of marine larvae. Microbially matured water treatment systems (MMS) provide a more favourable rearing water microbiome than flow-through systems (FTS). It has previously ... -
The effect of periodic disturbances and carrying capacity on the significance of selection and drift in complex bacterial communities
Gundersen, Madeleine S.; Vadstein, Olav; Bakke, Ingrid; Andersen, Tom; Morelan, Ian (Peer reviewed; Journal article, 2021)Understanding how periodical disturbances affect the community assembly processes is vital for predicting temporal dynamics in microbial communities. However, the effect of dilutions as disturbances are poorly understood. ... -
The impact of phage treatment on bacterial community structure is minor compared to antibiotics
Gundersen, Madeleine S.; Fiedler, Alexander Willi; Bakke, Ingrid; Vadstein, Olav (Peer reviewed; Journal article, 2023)Phage treatment is suggested as an alternative to antibiotics; however, there is limited knowledge of how phage treatment impacts resident bacterial community structure. When phages induce bacterial lysis, resources become ... -
Phage therapy minimally affects the water microbiota in an Atlantic salmon (Salmo salar) rearing system while still preventing infection
Fiedler, Alexander Willi; Gundersen, Madeleine S.; Vo, Toan Phuc; Almaas, Eivind; Vadstein, Olav; Bakke, Ingrid (Peer reviewed; Journal article, 2023)Excessive usage of antibiotics threatens the bacterial diversity in the microbiota of animals. An alternative to antibiotics that has been suggested to not disturb the microbiota is (bacterio)phage therapy. In this study, ... -
Robust bacterial co-occurence community structures are independent of r- and K-selection history.
Pettersen, Jakob Peder; Gundersen, Madeleine S.; Almaas, Eivind (Peer reviewed; Journal article, 2021)Selection for bacteria which are K-strategists instead of r-strategists has been shown to improve fish health and survival in aquaculture. We considered an experiment where microcosms were inoculated with natural seawater ...
