Comparative transcriptomics reveals candidate carotenoid color genes in an East African cichlid fish
Ahi, Ehsan Pashay; Lecaudey, Laurene Alicia; Ziegelbecker, Angelika; Steiner, Oliver; Glabonjat, Ronald; Goessler, Walter; Hois, Victoria; Wagner, Carina; Lass, Achim; Sefc, Kristina M (Journal article; Peer reviewed, 2020)Background Carotenoids contribute significantly to animal body coloration, including the spectacular color pattern diversity among fishes. Fish, as other animals, derive carotenoids from their diet. Following uptake, ... -
Expression levels of the tetratricopeptide repeat protein gene ttc39b covary with carotenoid-based skin colour in cichlid fish
Ahi, Ehsan Pashay; Lecaudey, Laurene Alicia; Ziegelbecker, Angelika; Steiner, Oliver; Goessler, Walter; Sefc, Kristina M (Peer reviewed; Journal article, 2020)Carotenoid pigments play a major role in animal body colouration, generating strong interest in the genes involved in the metabolic processes that lead from their dietary uptake to their storage in the integument. Here, ... -
Fish diversity assessment in the headwaters of the Volga River using environmental DNA metabarcoding
Lecaudey, Laurene Alicia; Schletterer, Martin; Kuzovlev, Vyacheslav V; Hahn, Christoph; Weiss, Stephen J. (Journal article; Peer reviewed, 2019)The headwaters of the Volga River exhibit large reaches with near‐pristine conditions, and therefore long‐term biodiversity monitoring of this catchment can provide rare and valuable information on a European lowland river. ... -
A holo-omics analysis shows how sugar kelp can boost gut health in Atlantic salmon
Rasmussen, Jacob A.; Bernhard, Annette; Lecaudey, Laurene Alicia; Kale, Varsha; Baldi, Germana; Myrmel, Lene Secher; Hansen, Martin; Brealey, Jaelle C.; Mak, Sarah S.T.; Nielsen, Ida B.; Richardson, Lorna; Madsen, Lise; Kristiansen, Karsten; Gilbert, M. Thomas P.; Martin, Michael David; Finn, Robert D.; Sveier, Harald; Limborg, Morten T. (Peer reviewed; Journal article, 2024)The projected growth of Aquaculture requires continuous optimisation of feeding regimes, especially in enhancing disease resilience through immunostimulating feed supplements. Seaweed has been introduced as a promising ... -
Host-gut microbiota interactions shape parasite infections in farmed Atlantic salmon
Brealey, Jaelle Caitlin; Kodama, Miyako; Agerbo Rasmussen, Jacob; Hansen, Søren B.; Santos-Bay, Luisa; Lecaudey, Laurene Alicia; Hansen, Martin; Fjære, Even; Myrmel, Lene Secher; Madsen, Lise; Bernhard, Annette; Sveier, Harald; Kristiansen, Karsten; Gilbert, M Thomas P; Martin, Michael David; Limborg, Morten Tønsberg (Journal article; Peer reviewed, 2024)Animals and their associated microbiota share long evolutionary histories. However, it is not always clear how host genotype and microbiota interact to affect phenotype. We applied a hologenomic approach to explore how ... -
Microbiome “Inception”: an Intestinal Cestode Shapes a Hierarchy of Microbial Communities Nested within the Host
Brealey, Jaelle; Lecaudey, Laurene Alicia; Kodama, Miyako; Rasmussen, Jacob A.; Sveier, Harald; Dheilly, Nolwenn M.; Martin, Michael David; Limborg, Morten Tønsberg (Journal article; Peer reviewed, 2022) -
Molecular mechanisms underlying nuchal hump formation in dolphin cichlid, Cyrtocara moorii
Lecaudey, Laurene Alicia; Sturmbauer, Christian; Singh, Pooja; Ahi, Ehsan Pashay (Journal article; Peer reviewed, 2019)East African cichlid fishes represent a model to tackle adaptive changes and their connection to rapid speciation and ecological distinction. In comparison to bony craniofacial tissues, adaptive morphogenesis of soft tissues ... -
Reference databases, primer choice, and assay sensitivity for environmental metabarcoding: Lessons learnt from a re‐evaluation of an eDNA fish assessment in the Volga headwaters
Schenekar, Tamara; Schletterer, Martin; Lecaudey, Laurene Alicia; Weiss, Steven (Journal article; Peer reviewed, 2020)Biodiversity monitoring via environmental DNA, particularly metabarcoding, isevolving into a powerful assessment tool for riverine systems. However, formetabarcoding to be fully integrated into standardized monitoring ... -
Transcriptomics unravels molecular players shaping dorsal lip hypertrophy in the vacuum cleaner cichlid, Gnathochromis permaxillaris
Lecaudey, Laurene Alicia; Singh, Pooja; Sturmbauer, Christian; Dünser, Anna; Gessl, Wolfgang; Ahi, Ehsan Pashay (Peer reviewed; Journal article, 2021)Background Teleosts display a spectacular diversity of craniofacial adaptations that often mediates ecological specializations. A considerable amount of research has revealed molecular players underlying skeletal ...
