Use of micronekton data and models to improve ecology of top predators
Typically, studies that focus on mid-to-high trophic-level species, such as fish and marine mammals, analyse data collected using instruments designed specifically to observe only a partial aspect of a single or small group or related species. For instance, mid-trophic level mesopelagic (200 to 1,00...
