The balance between energy acquisition and expenditure is critical to the survival and reproductive success of animals. Here we investigate the long-term effects of diet quality on physiological and life-history flexibility in the harvestman, Pachylus paessleri. We used cow meal as a protein-rich diet and potatoes as a carbohydrate-rich diet in order to reproduce two extreme conditions regarding food quality in harvestmen natural habitat. As proxy variables of the energy expenditure process, we… Expand
Effect of Diet Quality on Survival and Reproduction of Adult Paederus fuscipes (Coleoptera: Staphylinidae)
TLDR
The survival and reproduction of the beetle Paederus fuscipes Curtis on diets that differed in macronutrient composition were investigated in the laboratory and the development of previtellogenic follicles was significantly affected by diet regime and days since starting a particular diet. Expand
Larval nutrition affects life history traits in a capital breeding moth
TLDR
The findings show that physiological processes regulate the composition of the different components of the adult body, and Diet effects occur as differences in overall body size and in relative allocation to these components. Expand
Physiological and Life-History Plasticity in a Harvestman Species: Contrasting Laboratory with Field Data
TLDR
How animals adopt different life history strategies according to the quality of the diet that is available is illustrated, which is correlated with phenotypic adjustments at the anatomical and physiological levels. Expand
EFFECTS OF TWO NATURAL DIETS ON THE RESPONSE OF THE PREDATOR ARMA CHINENSIS (HEMIPTERA: PENTATOMIDAE: ASOPINAE) TO COLD STORAGE

  • Biology
  • Applied Ecology and Environmental Research
  • 2019
TLDR
The results suggested that the nutrient content of diets affects the accumulation of cold-resistant substances, metabolism level and activities of related enzymes in A. chinensis in a manner that enhances tolerance to cold storage. Expand
Larval nutrition impacts survival to adulthood, body size and the allometric scaling of metabolic rate in adult honeybees.
TLDR
The results are critical to improving understanding of the impacts of poor developmental nutrition on bee growth/development and physiology, given that agricultural intensification and increasing urbanisation have led to a decrease in both forage availability and dietary diversity for bees. Expand
Experimental Evidence for Nutrition Regulated Stress Resistance in Drosophila ananassae
TLDR
Drosophila ananassae adapts different stress tolerance and life-history strategies according to the quality of the available diet, which are correlated with phenotypic adjustment at anatomical and physiological levels. Expand
Impacts of temperature on metabolic rates of adult Extatosoma tiaratum reared on different host plant species
TLDR
Assessment of the responses of a generalist leaf feeder reared continuously on one of three host plants, tree lucerne, bramble and Eucalyptus species, in a low fluctuating temperature environment until adulthood to understand the impact that thermal stress will have on the growth, development, performance and survival of insects in a more variable climatic and nutritional landscape. Expand
Food dependent changes of the life history traits of Catopsilia pyranthe (Lepidoptera: Pieridae)
TLDR
In urban regions like Kolkata, India, disparity in food availability may induce variations in life history traits and thus fitness and survival in C. pyranthe may be affected. Expand
Development, metabolism and nutrient composition of black soldier fly larvae (Hermetia illucens; Diptera: Stratiomyidae) in relation to temperature and diet
TLDR
The MR of H. illucens larvae was found to increase with temperature, leading to a higher food in prepupa larvae, and the body nutrient composition in the sixth instar larvae was measured. Expand
Food supplementation and testosterone interact to influence reproductive behavior and immune function in Sceloporus graciosus
TLDR
The energetic state of the animal plays a critical role in modulating the interactions among T, behavior and immunity in sagebrush lizards and likely other species, and is shown to affect trade-offs among competing functions. Expand

Effects of food supplementation on the physiological ecology of female Western diamond-backed rattlesnakes (Crotalus atrox)
TLDR
A supplemental feeding study on free-ranging, female Western diamond-backed rattlesnakes (Crotalus atrox), a species with low energy demands and infrequent reproductive investment, demonstrates that food availability can directly impact some life history traits, but not others. Expand
Dietary glycerol and adult access to water: effects on fecundity and longevity in the almond moth.
TLDR
The results show that wet larval diets containing glycerol significantly decreased fecundity, whilst it significantly increased male and female longevity, whilst the possibility that larval diet can affect female reproductive decisions is discussed. Expand
The Effect of Standard Metabolic Rate on Egg Production in the Acridid Grasshopper, Xanthippus corallipes'
TLDR
The relationship between thermoregulation, standard metabolism, and egg production was investigated in adult females of the acridid grasshopper Xanthippus corallipes from six populations along an elevation gradient, revealing that intermediate values of field standard metabolic rate correlate with high egg production, suggesting stabilizing selection on standard metabolic rates. Expand
Effect of Enhanced Dietary Nitrogen on Reproductive Maturation of the Termite Zootermopsis angusticollis (Isoptera: Termopsidae)
TLDR
It is suggested that although enhancing dietary nitrogen may release newly molted neotenics from nutritional limitations on their fecundity, dietary enhancement with 0.05% uric acid does not significantly effect the reproductive development of recently dealated primaries. Expand
Gut size changes in relation to variable food quality and body size in grasshoppers
TLDR
Diet dilution greatly influenced the survival, development, weight gain and the proportional allocation to gut dry weight relative to body dry weight of Melanoplus differentialis (Orthoptera: Acrididae); increased gut size contributed to the ability to compensate for reduced food quality. Expand
Diet quality does not affect resting metabolic rate or body temperatures selected by an herbivorous lizard
TLDR
It is concluded that ecologically relevant differences in diet quality may have negligible effects on resting metabolic rates and body temperatures selected by chuckwallas. Expand
The Relationship between Diet Quality and Basal Metabolic Rate in Endotherms: Insights from Intraspecific Analysis
In this article, we review intraspecific studies of basal metabolic rate (BMR) that address the correlation between diet quality and BMR. The “food‐habit hypothesis” stands as one of the mostExpand
The Influence of Food Habits on the Energetics of Eutherian Mammals
TLDR
The level of energy expenditure in eutherian mammals is correlated with the type of food consumed, especially in medium—sized to large species; some foods permit high basal rates, while other foods require low basal rates. Expand
Effects of soybean proteinase inhibitor on development, survival and reproductive potential of the sugarcane borer, Diatraea saccharalis
TLDR
The purpose of this research was to calculate demographic statistics for the sugarcane borer reared on diet either with or without semi‐purified extract of SPI, indicating a potential value of using SPI for protecting Sugarcane plants against damage by the sugarborer. Expand
The metabolic basis of life history variation: genetic and phenotypic differences in lipid reserves among life history morphs of the wing-polymorphic cricket, Gryllus firmus.
TLDR
This is the first study to document genetically-based differences in energy reserves between morphs of a complex (phase, caste, flight) polymorphism in which morphs also differ genetically in key life history traits. Expand
