9 wrz 2020 · Our results suggest that abundances of large marine animals (whales, sharks, large fishes) have been significantly reduced by human hunting and fishing (causing a to be much closer to or less than 1 in modern marine ecosystems) [47–49]. Future research focusing on food webs and energy flow through entire ecosystems would provide the necessary ...
29 lip 2019 · Here we investigate how the distribution of trophic interactions at the global scale shapes the marine fish food web structure.
6 maj 2021 · Structure of the food web. Mean δ 15 N values ranged from 6.84‰ to 14.95‰ with the bivalve mollusk, P. maximus, showing the lowest δ 15 N values, and the large predatory fish, Atlantic cod G. morhua, the highest values (Table 1).
23 mar 2023 · Zooplankton are a critical component of marine food webs, serving as the primary energy pathway from phytoplankton to fish 1. Zooplankton are extremely diverse, representing 15 phyla 2 and...
12 mar 2022 · Since the 2000s most species increased their reliance on food webs supported by pelagic production, compared to coastal production supported by macroalgae, and shifted to a higher trophic level.
17 maj 2018 · Climatic constraints on fish body size (the Arctic fish being smaller than boreal fish) and their ecological niche space (Arctic fish being more specialized than boreal fish) result in regionally distinct food-web structures.
6 gru 2017 · We highlight key interactions within the poorly understood ‘jelly web’, showing the importance of medusae, ctenophores and siphonophores as key predators, whose ecological significance is comparable to large fish and squid species within the central California deep pelagic food web.
