Key Drivers of Ecological Assembly in the Hindgut of Atlantic Cod (Gadus morhua) when Fed with a Macroalgal Supplemented diet – How Robust Is the Gut to Taxonomic Perturbation?

Abstract: The microbiota in the gastrointestinal tract of any species is shaped by internal and external cues in addition to random events which can be difficult to disentangle from a range of interacting variables. Estimating ecological assembly processes can help elucidate these factors. In our study, farmed Atlantic cod (Gadus morhua) were fed a diet of 10% macroalgae supplement (Ulva rigida species [ULVA] or Ascophyllum nodosum [ASCO] or a non-amended control diet [CTRL]) over a 12-week period and the ecological ass… Show more

“…This will allow for basic diversity statistics, the identification of discriminant taxa and a core microbiome (e.g., [ 43 ]). However, for more advanced ecological modelling to be applied, usually a minimum of five to six replicates are required; this will usually satisfy criteria for the null models which often underpin community assembly analysis (e.g., [ 18 , 44 , 45 ]). Finally, for even more involved methods such as network inferences, upwards of 35 samples per category are often necessary to obtain reliable results (e.g., [ 46 , 47 ]).…”

“…Using simulated stochastic and deterministic metacommunities, Tucker et al (2016) were able to use the abundance-based ß-null deviation measures to differentiate between niche and neutral community assembly. This has since been applied to understand the community assembly of fish (Atlantic cod) microbiomes [ 45 ] and marine bioplankton [ 19 ].…”
