“…The magnesium content, Fig. 2 and concentration factor of Spicara smaris and Synodus saurus are ranged between 45.58 and 107.84 mg g¯1 and 68.97 and 163.17 at Sidi Barrani sector, respectively, may be related to the type of feeding of the two species [19] . Generally, the present study shows that the fish which live on the bottom of the sea water contain higher magnesium content than the pelagic ones.…”

“…The algal species in Abu Qir are of high phosphorus contents, Table 3 and may be attributed to the metabolic reactions [10] , environmental conditions [10] and seasonal variation [10] . Nearly half of the phosphorus in fish is located in bone and scales [19] . Fish are often long lived and thus can serve as reservoirs of nutrients [19] .…”

“…The phosphorus content of the whole body of Hippocampus hippocampus collected from Damietta is of 25.546 mg g¯1 to reflect its high content in the bone skeleton [19] . The phosphorus contents of the whole body of Cottus bairdi and Lota lota were 26.8 ± 2.4 and 19.1 ± 2.4 mg g¯1 collected from Bark Bay, Wisconsin, respectively [19] . However, the content is not only dependent on trophic level, location and length but also depends on both growth rate indices and fineness [19] .…”

-High pressure and temperature were combined with the convenient mixture of acids to perform an effective digestion of samples from aquatic animals for phosphorus (P) analysis. Our results indicate that digestion in high-pressure bombs combined with concentrated acidic media can be a convenient way to yield all P stored in samples, and to produce accurate recoveries. Phosphorus recovery of a certified standard material (94% ¡ 15) and digestions of aquatic animal tissues confirmed the relevance of bomb decomposition, as well as its reliability compared to ashing and microwave oven digestion methods. Moreover, the applied digestion technique is easily manageable even in samples consisting of a few individuals. This method is relatively rapid, saves money and time, and is able to recover P from the most persistent components (e.g. bones, scales, fat) of aquatic animal tissues.

Intraspecific variability modulates interspecific variability in animal organismal stoichiometry

Interspecific differences in organismal stoichiometry (OS) have been documented in a wide range of animal taxa and are of significant interest for understanding evolutionary patterns in OS. In contrast, intraspecific variation in animal OS has generally been treated as analytical noise or random variation, even though available data suggest intraspecific variability in OS is widespread. Here, we assess how intraspecific variation in OS affects inferences about interspecific OS differences using two co-occurring Neotropical fishes: Poecilia reticulata and Rivulus hartii. A wide range of OS has been observed within both species and has been attributed to environmental differences among stream systems. We assess the contributions of species identity, stream system, and the interactions between stream and species to variability in N:P, C:P, and C:N. Because predation pressure can impact the foraging ecology and life-history traits of fishes, we compare predictors of OS between communities that include predators, and communities where predators are absent. We find that species identity is the strongest predictor of N:P, while stream or the interaction of stream and species contribute more to the overall variation in C:P and C:N. Interspecific differences in N:P, C:P, and C:N are therefore not consistent among streams. The relative contribution of stream or species to OS qualitatively changes between the two predation communities, but these differences do not have appreciable effects in interspecific patterns. We conclude that although species identity is a significant predictor of OS, intraspecific OS is sometimes sufficient to overwhelm or obfuscate interspecific differences in OS.
