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 ... -
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 ...
