WebThe structure of most pelagic food webs can be thought of as a hybrid between the traditional food web, dominated by herbivory, and the microbial loop (Legendre & Rassoulzadegan 1995). Systems domi-nated by the herbivorous web, hereafter called ‘her-bivorous food webs’, mainly occur in nutrient-rich environments, rely on phytoplankton ... WebPelagic fish, by definition, are found near the ocean surface or in middle depths. As a result, pelagic fisheries must search larger volumes than demersal fisheries. However, most …
Food webs are networks of feeding interactions that encompass overall energy flow between resources and consumers within a given ecosystem. These interlocking food chains are an established, central foundation of modern ecological investigations [1,2]. The backbone of a food web investigation … See more This study represents the first attempt to delineate the food web structure of a deep pelagic ecosystem based on in situ ROV observations … See more Appropriate ethical approval and permits to conduct remotely operated vehicle surveys were obtained under National Marine Sanctuary Permit MBNMS-2015-002.

Webthereby linking pelagic and benthic food chains (Schin-dler et al. 1996, 1997). A number of food web config-urations can be envisioned depending on the extent of trophic flows between littoral and pelagic food chains. At one extreme is the scenario of two unlinked food chains, indicating food chain specialization on the part of consumers.
