29 lip 2019 · Here we investigate how the distribution of trophic interactions at the global scale shapes the marine fish food web structure.
19 lip 2022 · CSIA analyses showed that the species has a trophic level consistent with omnivory. Fatty acid profiles of whale shark tissues, feces and potential prey items suggest that the floating macroalgae, Sargassum, and its associated epibionts is a significant source of food. Although this overcomes the energetic challenge of consumption of floating ...
21 godz. temu · Climate change is altering the distribution of many marine fish species, with widespread impacts on biodiversity, with the potential to jeopardise world food security. Most studies to date focus on how commercially exploited fish species will be affected by climate change without consideration for different life stages across different species.
28 lip 2021 · We measured the breadth of fish species’ trophic niches, computed as the proportion of resources to which they were connected, to explore whether coral reef food webs were dominated by species with narrow or wide dietary preferences. On average, fish species were linked to 19% ± 0.05 of prey resources.
10 lip 2020 · In particular, the food sources at the species levels are critical components linking organisms with larger predatory species such as crustaceans and fish within the grazing food chain: rotifers-copepods, micro/macroinvertebrates, and larval/mature fish [2, 3].
9 gru 2021 · We hypothesise that food webs in cooler lakes follow the classical food chain concept with larger fish eating the smaller, whereas in warmer lakes the high dominance of omnivorous fish alters these relationships and shortens the length of the food web.
Zooplankton are eaten by the 1st level carnivorous consumers, which includes juvenile stages of larger animals like fish and jellyfish as well as small fish and crustaceans. 2nd and 3rd level carnivorous consumers include larger fish and some species of squid and octopus.
