Abstract Heterotrophic organisms must obtain essential elements in sufficient quantities from their food. Because plants naturally exhibit extensive variation in their elemental content, it is important to quantify the within-species stoichiometric variation of consumers. If extensive stoichiometric variation exists, it may help explain consumer variation in life-history strategy and fitness. To date, however, research on stoichiometric variation has focused on interspecific differences and…

Genotypic differences in phosphorus use physiology in producers (Chlamydomonas reinhardtii) and consumers (Daphnia pulex) interact to alter primary and secondary production
TLDR
Significant differences in C:P stoichiometry are found between the two Chlamydomonas genotypes in both P supply conditions, which highlight the potential ecological relevance of intraspecific differences in nutrient use physiology and elemental composition, and the utility of ecological stoichiometric in understanding such consequences.
Widespread natural intraspecific variation in tissue stoichiometry of two freshwater molluscs: Effect of nutrient enrichment
Variation in C:N:S Stoichiometry and Nutrient Storage Related to Body Size in a Holometabolous Insect (Curculio davidi) (Coleoptera: Curculionidae) Larva
TLDR
The results showed that weevil larvae with larger body mass had a lower carbon content, reflecting decreases in the sequestration rate of C-rich lipids, and larger larvae had elevated concentrations of nitrogen, sulfur, and protein, indicating that the shift in nutrient storage is the main factor causing the variation in larval stoichiometry with body weight.
Exploring patterns and mechanisms of interspecific and intraspecific variation in body elemental composition of desert consumers
TLDR
The results suggest that structural differences in material allocation, trophic level and phylogeny can all contribute to variation in the stoichiometry of desert consumers, and they indicate that the elemental composition of animals can be useful information for identifying broad-scale linkages between nutrient cycling andtrophic interactions in terrestrial food webs.
Differences in phosphorus use between ancient and extant Daphnia genotypes alters algal stoichiometry and abundance
TLDR
The potential for intraspecific variation in P-use physiology in affecting trophic interactions via consumer-driven nutrient recycling is highlighted, highlighting the evolutionary sources and ecological consequences of such variation.
Energy storage and C:N:P variation in a holometabolous insect (Curculio davidi Fairmaire) larva across a climate gradient.
Body stoichiometry of heterotrophs: assessing drivers of interspecific variations in elemental composition
TLDR
A global synthesis of body stoichiometry of heterotrophs reveals a strong interspecific variability that is only modestly explained by the species attributes investigated: body mass, habitat and diet, and further reveals that this taxonomically structured residual variation in body Stoichiometry seems to be constrained along taxonomic group-specific elemental spectrums.
Plant Fertilization Interacts with Life History: Variation in Stoichiometry and Performance in Nettle-Feeding Butterflies
TLDR
The results partly supported the prediction that host plant specificity affects larval sensitivity to food stoichiometry and suggested that most of the differences observed may be explained by differences in voltinism (number of generations per year).
Ecological mechanisms and phylogeny shape invertebrate stoichiometry: A test using detritus‐based communities across Central and South America
TLDR
Analyzing elemental composition of aquatic macroinvertebrates shows that both ecological and evolutionary drivers explain among-taxa variation in the elemental content of invertebrates, whereas intraspecific variation is mainly a function of body size.
Stoichiometry of a semi-aquatic plethodontid salamander: intraspecific variation due to location, size and diet.
TLDR
This study suggests that spatial differences in environmental nutrient supply have a stronger influence on consumer whole-body stoichiometry among similar-sized larvae compared to life history traits, such as body size or diet.

Elemental stoichiometry of Drosophila and their hosts
TLDR
Total body N and P contents were determined in seven species of wild-caught Drosophila, their natural hosts, and artificial diets routinely used to rear these flies in the laboratory, suggesting phosphorus demands during oogenesis are high.
Nitrogen in Insects: Implications for Trophic Complexity and Species Diversification
TLDR
Using a recently compiled database on insect nutrient content, it is found that predators exhibit on average 15% greater nitrogen content than herbivores, and evidence that recently derived lineages have, on a relative basis, 15%–25% less body nitrogen than more ancient herbivore lineages.

Consequences of nitrogen and phosphorus limitation for the performance of two planthoppers with divergent life-history strategies
TLDR
This research highlights the importance of interfacing herbivore life-history strategies with ecological stoichiometry in order to interpret the consequences of macronutrient limitation on Herbivore performance and population dynamics.
Nutritional constraints in terrestrial and freshwater food webs
TLDR
In both lakes and terrestrial systems, herbivores should have low growth efficiencies when consuming autotrophs with typical carbon-to-nutrient ratios and stoichiometric constraints on herbivore growth appear to be qualitatively similar and widespread in both environments.
Growth rate–stoichiometry couplings in diverse biota
TLDR
The close relationship between P and RNA contents indicates that ribosomes themselves represent a biogeochemically significant repository of P in ecosystems and that allocation of P to ribosome generation is a central process in biological production in ecological systems.
Allometric and phylogenetic variation in insect phosphorus content
TLDR
Phosphorus contents of insect predators and herbivores were statistically indistinguishable and more recently derived orders tended to have lower phosphorus contents – with the exception of the most recently derived group, which had high phosphorus contents.
Stoichiometric tracking of soil nutrients by a desert insect herbivore
TLDR
Tight association between soil, plant and herbivore P provides the first evidence of a mechanistic pathway linking P biogeochemistry to terrestrial food webs by altering the supply of dietary P to herbivores, thus limiting their capacity for growth by constraining the production of P-rich cellular ribosomal RNA (rRNA).
Relationship Between N:P Ratio and Growth Rate During the Life Cycle of Calanoid Copepods: An in situ Measurement
TLDR
The results tend to support the hypothesis linking specific growth rate with P content for copepods, but suggest that the validity of this hypothesis is robustness when differences in the life history ofCopepods as a consequence of metamorphosis are accounted for.
Herbivory in relation to plant nitrogen content
TLDR
The evidence that N is scarce and perhaps a limiting nutrient for many herbivores, and that in response to this selection pressure, many Herbivores have evolved specific behavioral, morphological, physiological, and other adaptations to cope with and uti­ lize the ambient N levels of their normal haunts is examined.
