  abstract = {{T}he connection between epipelagic and deep-sea mesopelagic realms controls a variety of ecosystem processes includ-ing oceanic carbon storage and the provision of harvestable fish stocks. {S}o far, these two layers have been mostly ad-dressed in isolation and the ways they connect remain poorly understood. {F}urthermore, both systems are affected by climate change, exploitation of resources, and increasing pervasion of pollutants. {H}ere we use bulk isotopes of delta 13{C} and delta 15{N} of 60 ecosystem components to evaluate the trophic linkage between epipelagic and mesopelagic ecosystems in warm oligotrophic waters. {A}dditionally, we we conducted a comparison of isotopic niche sizes and overlaps across multiple species to evaluate how environmental gradients between epipelagic and mesopelagic ecosystems shape eco-logical patterns of resource use and competition between species. {O}ur database comprises siphonophores, crustaceans, particulate organic matter collected at different depths. {T}hrough this wide taxonomic and trophic variety of epipelagic and mesopelagic species, we show that pelagic species access resources originating from different food sources, mostly autotrophic-based (epipelagics) and microbial heterotrophic-based (mesopelagics). {T}his leads to a sharp trophic dis-similarity between vertical layers. {A}dditionally, we show that trophic specialization increases in deep-sea species and argue that food availability and environmental stability are among the main drivers of this pattern. {F}inally, we dis-cuss how the ecological traits of pelagic species highlighted in this study can respond to human impacts and increase their vulnerability in the {A}nthropocene.},
