Might macronutrient requirements influence grizzly bear–human conflict? Insights from nutritional geometry

Revisiting macronutrient regulation in the polyphagous herbivore Helicoverpa zea (Lepidoptera: Noctuidae): New insights via nutritional geometry.

Insect herbivores that ingest protein and carbohydrates in physiologically-optimal proportions and concentrations show superior performance and fitness. The first-ever study of protein-carbohydrate regulation in an insect herbivore was performed using the polyphagous agricultural pest Helicoverpa zea. In that study, experimental final instar caterpillars were presented two diets - one containin...

Insights from Agricultural and Forestry GHG Offset Studies that Might Influence IAM Modeling

Conflict-Oriented Requirements Restructuring

Requirements engineering necessitates the analysis of relationships among the requirements of system stakeholders. Poor analysis of these relationships has led to numerous failures. To improve such analysis, researchers have created models and methods for recording, analyzing, and modifying stakeholder requirements. However, the critical aspect of representing and reasoning about stakeholder in...

The nutritional geometry of parental effects: maternal and paternal macronutrient consumption and offspring phenotype in a neriid fly

1. Although the ecological and evolutionary importance of environmentally induced parental effects is now widely recognized, such effects are still typically studied by contrasting just two environments in a single parental sex. Yet, parental effects should generally be viewed as reaction norms, and a more complete understanding of their ecological role therefore requires examining continuously...

Guidelines for specialized nutritional and metabolic support in the critically-ill patient: update. Consensus SEMICYUC-SENPE: macronutrient and micronutrient requirements.

Energy requirements are altered in critically-ill patients and are influenced by the clinical situation, treatment, and phase of the process. Therefore, the most appropriate method to calculate calorie intake is indirect calorimetry. In the absence of this technique, fixed calorie intake (between 25 and 35 kcal/kg/day) or predictive equations such as the Penn State formula can be used to obtain...
