  abstract = {{E}cosystem models are currently one of the most powerful approaches used to project and analyse the consequences of anthropogenic and climate-driven changes in food web structure and function. {T}he modeling community is however still finding the effective representation of microbial processes as challenging and lacks of techniques for assessing flow uncertainty explicitly. {A} linear inverse model of the {B}ay of {B}iscay continental shelf was built using a {M}onte {C}arlo method coupled with a {M}arkov {C}hain ({LIM}-{MCMC}) to characterize the system's trophic food-web status and its associated structural and functional properties. {B}y taking into account the natural variability of ecosystems (and their associated flows) and the lack of data on these environments, this innovative approach enabled the quantification of uncertainties for both estimated flows and derived food-web indices. {T}his uncertainty assessment constituted a real improvement on the existing {E}copath model for the same area and both models results were compared. {O}ur results suggested a food web characterized by main flows at the basis of the food web and a high contribution of primary producers and detritus to the entire system input flows. {T}he developmental stage of the ecosystem was characterized using estimated {E}cological {N}etwork {A}nalysis ({ENA}) indices; the {LIM}-{MCMC} produced a higher estimate of flow specialization (than the estimate from {E}copath) owing to better consideration of bacterial processes. {T}he results also pointed to a detritus-based food-web with a web-like structure and an intermediate level of internal flow complexity, confirming the results of previous studies. {O}ther current research on ecosystem model comparability is also presented.},
