“…32 Thus, it is possible that the females in this study had different energy consumption and/or different body composition when conception occurred and such variation might have contributed to the effect on the offspring. An important role of dietary protein density in the diets of mice, 32 as well as humans 33 and non-human primates, 34 is that it can influence health through its 'leverage' on calorie intake. 35 Although further work is needed to disentangle the effects of dietary protein content on energy intake per se vs the balance of ingested macronutrients, our experiments have shown that the balance of macronutrients in foods of preconceptional females has effect on the developmental trajectories of their offspring.…”

Background: Maternal nutrition during pregnancy or lactation may affect the chance of offspring becoming obese as adults, but little is known regarding the possible role of maternal nutrition before conception. In this study, we investigate how variable protein and carbohydrate content of the diet consumed before pregnancy affects fat deposition and gut dimensions of offspring mice. Methods: Eight-week-old female mice (C57BL/6JBom) were fed isocaloric low protein (8.4% protein; LP), standard protein (21.5% protein; ST) or high protein (44.2% protein; HP) diets. After 8 weeks of feeding, females were mated and fed a standard laboratory chow diet (22.5% protein) throughout periods of mating, gestation, lactation and weaning. Offspring mice were fed the same standard diet up to 46 days of age. Then offspring were killed and measures of dissected fat deposits and of the digestive system were taken. Results: Fat deposition of the offspring was significantly affected by preconceptional maternal nutrition and the effects differed between sexes. Male offspring deposited most fat when mothers were fed the LP diet, whereas female offspring deposited most fat when mothers were fed the ST diet. The mass and length of the digestive organs were affected by preconceptional maternal nutrition. Total gut from pyloric sphincter to anus was significantly shorter and dry mass was heavier in mice whose mothers were fed LP diets compared with offspring of mothers fed ST diets or HP diets. There was no significant effect of maternal nutrition on dry mass of the stomach or ceca. Conclusion: Our study shows that preconceptional nutrition can have important influence on several body features of offspring in mice, including body composition and dimensions of the digestive system.

“…A recent example where nutritional geometry was used to understand the habitat requirements of a priority conservation species was the study of Peruvian spider monkeys, Ateles chamek, in their natural forested habitat in Bolivia (Felton et al 2009a(Felton et al , 2009b. Felton first spent five months habituating the monkeys.…”

“…The study of Felton et al (2009aFelton et al ( , 2009b has several implications for understanding the habitat requirements of Peruvian spider monkeys. First, the results provide an estimate of the position of the macronutrient intake target of monkeys, and suggest that figs (Ficus spp.)…”

Abstract. We present a graphical approach, which we believe can help to integrate nutrition into the broader biological sciences, and introduce generality into the applied nutritional sciences. This 'Geometric Framework' takes account of the fact that animals need multiple nutrients in changing amounts and balance, and that nutrients come packaged in foods that are often hard to find, dangerous to subdue and costly to process. We then show how the Geometric Framework has been used to understand the links between nutrition and relevant aspects of the biology of individual animals. These aspects include the physiological mechanisms that direct the nutritional interactions of the animal with its environment, and the fitness consequences of these interactions. Having considered the implications of diet for individuals, we show that these effects can translate into the collective behaviour of groups and societies, and in turn ramify throughout food webs to influence the structure of ecosystems.

“…A recent study in wild primates showed that contrary to prevailing views, spider monkeys prioritized acquisition of protein not bound by tannins over energy across many days of individual foraging (Felton et al, 2009). In contrast, similar studies of wild gorillas found no prioritization of protein (Rothman et al, 2011).…”

“…Another reason is that researchers tend to regard nutrients as "therapeutic" components that always result in positive consequences whereas PSMs are considered "toxic" components with inevitable negative repercussions. As such, PSMs (Cruz-Rivera and Hay, 2003;Duffy and Paul, 1992;Felton et al, 2009;Van Alstyne et al, 2009), in others, PSMs are more important (Dearing et al, 2000;Erhard et al, 2007), and in still other cases, these factors are equally important or act synergistically to influence foraging behavior (Duffy and Paul, 1992;Frye et al in press, Simpson and Raubenheimer, 2001). While approaches, such as the geometric framework, have helped researchers study how herbivores regulate nutrient needs in variable nutritional and PSM environments (Behmer, 2009), what remains poorly understood is why certain species respond to specific thresholds of PSMs or nutrients and others do not.…”

A Pharm-Ecological Perspective of Terrestrial and Aquatic Plant-Herbivore Interactions

-We describe some recent themes in the nutritional and chemical ecology of herbivores and the importance of a broad pharmacological view of plant nutrients and chemical defenses that we integrate as "Pharm-ecology". The central role that dose, concentration, and response to plant components (nutrients and secondary metabolites) play in herbivore foraging behavior argues for broader application of approaches derived from pharmacology to both terrestrial and aquatic plant-herbivore systems. We describe how concepts of pharmacokinetics and pharmacodynamics are used to better understand the foraging phenotype of herbivores relative to nutrient and secondary metabolites in food. Implementing these concepts into the field remains a challenge but new modeling approaches that emphasize tradeoffs and the properties of individual animals show promise. Throughout we highlight similarities and differences between the historic and future applications of pharm-ecological concepts in understanding the ecology and evolution of terrestrial and aquatic interactions between herbivores and plants. We offer several pharm-ecology related questions and hypotheses that could strengthen our understanding of the nutritional and chemical factors that modulate foraging behavior of herbivores across terrestrial and aquatic systems.
