The metabolic pace-of-life model: incorporating ectothermic organisms into the theory of vertebrate ecoimmunology.

Mechanisms and methods in ecoimmunology: integrating within-organism and between-organism processes.

Ecoimmunology utilizes techniques from traditionally laboratory-based disciplines--for example, immunology, genomics, proteomics, neuroendocrinology, and cell biology--to reveal how the immune systems of wild organisms both shape and respond to ecological and evolutionary pressures. Immunological phenotypes are embedded within a mechanistic pathway leading from genotype through physiology to sh...

Selected contribution: long-lived Drosophila melanogaster lines exhibit normal metabolic rates.

The use of model organisms, such as Drosophila melanogaster, provides a powerful method for studying mechanisms of aging. Here we report on a large set of recombinant inbred (RI) D. melanogaster lines that exhibit approximately a fivefold range of average adult longevities. Understanding the factors responsible for the differences in longevity, particularly the characteristics of the longest-li...

Ingredients for Good Health Policy-Making: Incorporating Power and Politics into the Mix

Developmental and Immediate Thermal Environments Shape Energetic Trade-Offs, Growth Efficiency, and Metabolic Rate in Divergent Life-History Ecotypes of the Garter Snake Thamnophis elegans.

Interactions at all levels of ecology are influenced by the rate at which energy is obtained, converted, and allocated. Trade-offs in energy allocation within individuals in turn form the basis for life-history theory. Here we describe tests of the influences of temperature, developmental environment, and genetic background on measures of growth efficiency and resting metabolic rate in an ectot...

Predicting nutrient excretion of aquatic animals with metabolic ecology and ecological stoichiometry: a global synthesis.

The metabolic theory of ecology (MTE) and ecological stoichiometry (ES) are both prominent frameworks for understanding energy and nutrient budgets of organisms. We tested their separate and joint power to predict nitrogen (N) and phosphorus (P) excretion rates of ectothermic aquatic invertebrate and vertebrate animals (10,534 observations worldwide). MTE variables (body size, temperature) perf...
