“…We only detected negative fitness consequences for phosphorus intake even though the range of total dietary phosphorus content used in this study (0.07-1.87%) encompasses the range used in the aforementioned studies (0.2-1%; [27,46]). A plausible explanation for the discrepancy between this and similar studies is that the lifetime phosphorus requirements of our study crickets may have been fulfilled during development, as our juvenile crickets were reared on phosphorus-rich (1.1% total Ph) diets, whereas the diets of juvenile crickets in previous studies were unknown for the first four to five instars following hatching [27,46]. However, we also reared juveniles on proteinand carbohydrate-adequate diets, suggesting that there might be fundamental differences in the critical ontogenetic periods and time scales over which macronutrients and phosphorus are required, with macronutrients dictating the biological responses at a finer temporal resolution than phosphorus.…”

“…Although other studies have shown that phosphorus influences invertebrate fitness [17,27,31,36,46], these studies were not designed to vary phosphorus orthogonally to protein and carbohydrates, and did not quantify the relative individual and interactive contributions of each nutrient to the animals' responses. By varying nutrients independently, we were able to measure the individual as well as interactive effects of phosphorus, protein and carbohydrate on a suite of fitness traits in male and female crickets.…”

“…Furthermore, females typically prefer males displaying higher-energy signals [39,42]. Given that higher-energy signals are more costly to produce [38,39] and are influenced by nutritional status [10,26,27,43], these signals may provide females with reliable information on indirect fitness benefits of mate choice (e.g. good genes for foraging in offspring).…”

“…Males produce acoustic mate attraction signals by rubbing their forewings together [25]. Overall signalling effort is influenced by diet [10,26,27] and females typically phonolocate towards higher-effort signallers [26,28].…”

Towards a synthesis of frameworks in nutritional ecology: interacting effects of protein, carbohydrate and phosphorus on field cricket fitness

Phosphorus has been identified as an important determinant of nutritionrelated biological variation. The macronutrients protein (P) and carbohydrates (C), both alone and interactively, are known to affect animal performance. No study, however, has investigated the importance of phosphorus relative to dietary protein or carbohydrates, or the interactive effects of phosphorus with these macronutrients, on fitness-related traits in animals. We used a nutritional geometry framework to address this question in adult field crickets (Gryllus veletis). Our results showed that lifespan, weight gain, acoustic mate signalling and egg production were maximized on diets with different P : C ratios, that phosphorus did not positively affect any of these fitness traits, and that males and females had different optimal macronutrient intake ratios for reproductive performance. When given a choice, crickets selected diets that maximized both lifespan and reproductive performance by preferentially eating diets with low P : C ratios, and females selected diets with a higher P : C ratio than males. Conversely, phosphorus intake was not regulated. Overall, our findings highlight the importance of disentangling the influences of different nutrients, and of quantifying both their individual and interactive effects, on animal fitness traits, so as to gain a more integrative understanding of their nutritional ecology.

“…In fact, the age×sex interaction observed is driven primarily by changes in female, not male, acquisition from late juvenility to adulthood. Late-stage juveniles differ from adults in that they must allocate resources to both a high overall growth rate and the development of reproductive traits, both processes that are highly C and P intensive (Bertram et al, 2009;Cothran et al, 2012;Elser et al, 1996Elser et al, , 2000Markow et al, 2001;Speakman, 2008;Visanuvimol and Bertram, 2010). One possible explanation for the observed age×sex interaction is that males are foraging at their maximum rate in both late juvenility and adulthood, because selection on these traits may be consistent across these two life stages.…”

Although sexually dimorphic traits are often well studied, we know little about sex-specific resource use strategies that should underlie such dimorphism. We measured sex-specific responses in acquisition and assimilation of two fundamental resources, carbon (C) and phosphorus (P) in juvenile and mature Hyalella amphipods given low and high supplies of inorganic phosphate, analogous to oligotrophic and eutrophic conditions, respectively. Additionally, we quantified allocation of resources to sexual traits in males. Dual radiotracer ( 14 C and 33 P) assays revealed substantial age-and sexspecific differences in acquisition and assimilation. Furthermore, a phenotypic manipulation experiment revealed that amphipods fed low-P food allocated more C to all traits than those fed high-P food. Importantly, we found that amphipods preferentially allocated more C to the development of a sexually selected trait (the posterior gnathopod), compared with a serially homologous trait (the fifth pereopod) not under sexual selection. Substantial differences in how the sexes use fundamental resources, and the impact of altered nutrient supply on such differences, illuminate sexual dimorphism at the lowest level of biological organization. Such information will be important in understanding how sex-and age-specific life history demands influence nutrient processing in a biosphere characterized by rapidly changing alterations to biogeochemical cycles.

The phenotypic variance–covariance matrix (P) describes the multivariate distribution of a population in phenotypic space, providing direct insight into the appropriateness of measured traits within the context of multicollinearity (i.e., do they describe any significant variance that is independent of other traits), and whether trait covariances restrict the combinations of phenotypes available to selection. Given the importance of P, it is therefore surprising that phenotypic covariances are seldom jointly analyzed and that the dimensionality of P has rarely been investigated in a rigorous statistical framework. Here, we used a repeated measures approach to quantify P separately for populations of four cricket species using seven acoustic signaling traits thought to enhance mate attraction. P was of full or almost full dimensionality in all four species, indicating that all traits conveyed some information that was independent of the other traits, and that phenotypic trait covariances do not constrain the combinations of signaling traits available to selection. P also differed significantly among species, although the dominant axis of phenotypic variation (pmax) was largely shared among three of the species (Acheta domesticus, Gryllus assimilis, G. texensis), but different in the fourth (G. veletis). In G. veletis and A. domesticus, but not G. assimilis and G. texensis, pmax was correlated with body size, while pmax was not correlated with residual mass (a condition measure) in any of the species. This study reveals the importance of jointly analyzing phenotypic traits.
