  abstract = {{T}he consequences of climate change for marine organisms are now well-known, and include metabolism and behavior modification, distribution area shifts and changes in the community. {I}n the {B}ay of {B}iscay, the potential environmental niches of subtropical non-indigenous species ({NIS}) are projected to expand as a response to sea temperature rise by the mid-century under the {RCP}8.5 climate change scenario. {I}n this context, this study aims to project the combined effects of changes in indigenous species distribution and metabolism and {NIS} arrivals on the functioning of the {B}ay of {B}iscay trophic network. {T}o do this, we created six different {E}copath food web models: a "current situation" trophic model (2007-2016) and five "future" trophic models. {T}he latter five models included various {NIS} biomass combinations to reflect different potential scenarios of {NIS} arrivals. {F}or each model, eight {E}cological {N}etwork {A}nalysis ({ENA}) indices were calculated, describing the properties of the food web resulting from the sum of interactions between organisms. {O}ur results illustrate that rising temperature increases the quantity of energy passing through the system due to increased productivity. {A} decrease in the biomass of some trophic groups due to the reduction of their potential environmental niches also leads to changes in the structure of the trophic network. {T}he arrival of {NIS} is projected to change the fate of organic matter within the ecosystem, with higher cycling, relative ascendency, and a chain-like food web. {I}t could also cause new trophic interactions that could lead to competition and thus modify the food-web structure, with lower omnivory and higher detritivory. {T}he combined impacts (increasing temperatures and {NIS} arrivals) could lower the resilience and resistance of the system.},
