The conclusion from this analysis is that low rates of metabolism, in the deep sea and elsewhere, do not result from resource limitation or temperature or pressure constraint, and high metabolic demand follows strong selection for locomotory capacity among visual predators inhabiting well-lit oceanic waters.
Plastic for dinner? Observations of frequent debris ingestion by pelagic predatory fishes from the central North Pacific
Ingested debris pieces were found to be positively buoyant in seawa- ter mimicking different depths, and suggest that more attention should be given to marine debris in subsurface waters as well as to poorly understood organismal and food web implications.
The influence of depth on mercury levels in pelagic fishes and their prey
Results indicate that total mercury levels of predatory pelagic fishes and their prey increase with median depth of occurrence in the water column and mimic concentrations of dissolved organic mercury in seawater, suggesting that the mesopelagic habitat is a major entry point for mercury into marine food webs.
Global Trophic Position Comparison of Two Dominant Mesopelagic Fish Families (Myctophidae, Stomiidae) Using Amino Acid Nitrogen Isotopic Analyses
It is found that trophic positions estimated from the δ15N values of individual amino acids are nearly uniform within both families of these fishes across five global regions despite great variability in bulk tissue δ 15N values.
Trophic position estimates of marine teleosts using amino acid compound specific isotopic analysis
The increasing use of trophic position (TP) for assessing and describing ecosystems has resulted in the emergence of novel techniques for accurate and accessible measurements. The strength of amino
Methylmercury production below the mixed layer in the North Pacific Ocean
We document a systematic decline in 202 Hg, 1 199 Hg and 1 201 Hg values with the depth at which fish feed. We show that these mercury isotope trends can be explained only if monomethylmercury is
Bypassing the abyssal benthic food web: Macrourid diet in the eastern North Pacific inferred from stomach content and stable isotopes analyses
Results of isotope mass balance suggest that carrion was the most important prey resource for both species but to a lesser extent in C. yaquinae, which bypass the conventional phytodetritus-based abyssal food web for much of their nutrition.
Lipid, sterols and fatty acid composition of abyssal holothurians and ophiuroids from the North-East Pacific Ocean: food web implications.
The lipid, fatty acid (FA), and sterol composition of two ophiuroids and four holothurians from the abyssal eastern North Pacific were analysed to assess their feeding habits and to ascertain their
Trophic structure and food resources of epipelagic and mesopelagic fishes in the North Pacific Subtropical Gyre ecosystem inferred from nitrogen isotopic compositions
We used bulk tissue d 13 C and d 15 N values and d 15 N values of individual amino acids (AA) to characterize the trophic structure of a pelagic fish assemblage from the North Pacific Subtropical
A continuum of life histories in deep-sea demersal fishes
Analysis of a suite of fishes from the shelves to the slope has shown that rather than a simple dichotomy between deep-sea fishes and shelf fishes there is a continuum of life history attributes in fishes which correlate strongly with depth of occurrence.
