Beyond taxonomy: Validating functional inference approaches in the context of fish-farm impact assessments
Laroche, Olivier; Pochon, Xavier; Wood, Susanna A.; Keeley, Nigel B. (Peer reviewed; Journal article, 2021)Characterization of microbial assemblages via environmental DNA metabarcoding is increasingly being used in routine monitoring programs due to its sensitivity and cost-effectiveness. Several programs have recently been ... -
Comparing sediment DNA extraction methods for assessing organic enrichment associated with marine aquaculture
Pearman, John K.; Keeley, Nigel B.; Wood, Susanna A.; Laroche, Olivier; Zaiko, Anastasija; Thomson-Laing, Georgia; Biessy, Laura; Atalah, Javier; Pochon, Xavier (Peer reviewed; Journal article, 2020)Marine sediments contain a high diversity of micro- and macro-organisms which are important in the functioning of biogeochemical cycles. Traditionally, anthropogenic perturbation has been investigated by identifying ... -
Ecosystems monitoring powered by environmental genomics: a review of current strategies with an implementation roadmap
Cordier, Tristan; Alonso Sáez, Laura; Apothéloz-Perret-Gentil, Laure; Aylagas, Eva; Bohan, David A.; Bouchez, Agnès; Chariton, Anthony; Creer, Simon; Frühe, Larissa; Keck, François; Keeley, Nigel B.; Laroche, Olivier; Leese, Florian; Pochon, Xavier; Stoeck, Thorsten; Pawlowski, Jan; Lanzén, Anders (Peer reviewed; Journal article, 2021)A decade after environmental scientists integrated high-throughput sequencing technologies in their toolbox, the genomics-based monitoring of anthropogenic impacts on the biodiversity and functioning of ecosystems is yet ... -
Effects of fish farm activities on the sponge Weberella bursa, and its associated microbiota
Laroche, Olivier; Meier, Sonnich; Mjøs, Svein A.; Keeley, Nigel B. (Peer reviewed; Journal article, 2021)Sustained growth of world-wide sea farming and the search of optimal growing conditions have driven several countries, including Norway, to establish new finfish sites in more exposed, high current locations. Characterized ... -
From sea surface to seafloor: A benthic allochthonous eDNA survey for the abyssal ocean
Laroche, Olivier; Kersten, Oliver; Smith, Craig R.; Goetze, Erica (Peer reviewed; Journal article, 2020)Environmental DNA (eDNA) metabarcoding could facilitate rapid and comprehensive biotic surveys in the deep ocean, yet many aspects of the sources and distribution of eDNA in the deep sea are still poorly understood. In ... -
Global Trends of Benthic Bacterial Diversity and Community Composition Along Organic Enrichment Gradients of Salmon Farms
Frühe, Larissa; Dully, Verena; Forster, Dominik; Keeley, Nigel B.; Laroche, Olivier; Pochon, Xavier; Robinson, Shawn; Wilding, Thomas A.; Stoeck, Thorsten (Peer reviewed; Journal article, 2021)The analysis of benthic bacterial community structure has emerged as a powerful alternative to traditional microscopy-based taxonomic approaches to monitor aquaculture disturbance in coastal environments. However, local ... -
Metabarcoding as a tool to enhance marine surveillance of nonindigenous species in tropical harbors: A case study in Tahiti
Pearman, John K.; Von Ammon, Ulla; Laroche, Olivier; Zaiko, Anastasija; Wood, Susanna A.; Zubia, Mayalen; Planes, Serge; Pochon, Xavier (Peer reviewed; Journal article, 2021)Globalization has increased connectivity between countries enhancing the spread of marine nonindigenous species (NIS). The establishment of marine NIS shows substantial negative effects on the structure and functioning of ... -
A Substrate-Independent Benthic Sampler (SIBS) for Hard and Mixed-Bottom Marine Habitats: A Proof-of-Concept Study
Keeley, Nigel B.; Laroche, Olivier; Birch, Murray; Pochon, Xavier (Peer reviewed; Journal article, 2021)Sea cage fish farms are increasingly situated over hard and mixed substrate habitats for production and waste-dispersion reasons; yet in many cases, these installations are not being effectively managed with respect to ... -
Suspension-feeding benthic species’ physiological and microbiome response to salmon farming and associated environmental changes
Laroche, Olivier; Meier, Sonnich; Mjøs, Svein Are; Keeley, Nigel B. (Peer reviewed; Journal article, 2022)Caged salmon farming is increasingly undertaken in water bodies with strong hydrodynamics where hard and mixed substrate habitats are more prevalent. Yet, these structurally complex and heterogeneous habitats support diverse ...
