Nitrogen-limited plants ofHeterotheca subaxillaris accumulate greater quantities of leaf volatile terpenes than do nitrogen-rich plants. A series of feeding trials were performed to determine if such nitrate-limited plants are better defended against generalist-feeding insect herbivores. Soybean looper (Pseudoplusia includens) larvae were fed leaves fromH. subaxillaris rosettes grown under high and low nitrate supply regimes. Larval consumption, growth, and survival declined as the leaf… 
Compensatory Feeding in Danaus plexippus (Lepidoptera: Nymphalidae) in Response to Variation in Host Plant Quality
TLDR
Results suggest that monarch larvae compensate for lower plant quality by consuming more, and if increased consumption is costly because of increased exposure to natural enemies or increased expenditure on consuming and processing food, low nitrogen host plants may result in decreased fitness, despite monarchs’ ability to compensate.
Plant biomass partitioning and chemical defense: Response to defoliation and nitrate limitation
TLDR
Nutrient stress resulting from reduced allocation to root growth withdefoliation may explain the greater allocation to carbon-based leaf defenses, as well as the defoliation-related greater growth reduction of nitrate-rich plants.
Changes in leaf mono- and sesquiterpene metabolism with nitrate availability and leaf age inHeterotheca subaxillaris
TLDR
The results suggest that the higher leaf volatile terpene content observed under nitrate limitation apparently results from increased synthesis per leaf and accumulation of mono- and sesquiterpenes in immature leaves of nitratepoor plants.
Carbon-nutrient balance hypothesis in within-species phytochemical variation ofSalix lasiolepis
TLDR
Predictions of the carbon-nutrient balance hypothesis were tested using a study of within-species phytochemical variation in the arroyo willow, Salix lasiolepis, and showed the strongest positive relationships with shoot length.
Higher Allocation to Low Cost Chemical Defenses in Invasive Species of Hawaii
TLDR
The results suggest that apart from greater growth rate and greater nutrient use, alien success in Oahu also may be linked to greater contents of low cost chemical defenses, such as terpenes, as expected in faster-growing species in resource rich regions.
Diet dependent experience and physiological state shape the behavior of a generalist herbivore
TLDR
The behavioral structure was very similar to earlier findings for another chrysomelid species, indicating a broader validity of the concept of personality dimensions in insects, and the importance of both experience- and state-dependence when investigating behavioral phenotypes.
Terpenes and phenolics in response to nitrogen fertilization: A test of the carbon/nutrient balance hypothesis
Nitrogen fertilization resulted in a linear increase in the growth ofAbies grandis seedlings, but linear decrease in foliage concentrations of phenolic compounds. These data are consistent with the
Sagebrush and grasshopper responses to atmospheric carbon dioxide concentration
TLDR
Seed- and clonally-propagated plants of Big Sagebrush were grown under atmospheric carbon dioxide regimes of 270, 350 and 650 μl l−1 and fed toMelanoplus differentialis and M. sanguinipes grasshoppers, and leaf nitrogen concentration was an important positive factor in grasshopper relative growth but had no overall effect on consumption.
Sagebrush carbon allocation patterns and grasshopper nutrition: the influence of CO2 enrichment and soil mineral limitation
TLDR
An overall negative relationship of consumption versus leaf volatile concentration suggests that terpenes may have been one of several important leaf characteristics limiting consumption of the low nutrient hosts.
The Panglossian paradigm and delayed inducible accumulation of foliar phenolics in mountain birch
We review some hypotheses for outlining how the nutrient status of deciduous woody plants may affect the accumulation of foliar phenolics, and how defoliation may alter the plant carbon/nutrient

Growth pattern and carbon allocation to volatile leaf terpenes under nitrogen-limiting conditions in Heterotheca subaxillaris (Asteraceae)
TLDR
Higher levels of carbon-based herbivore-deterring chemicals in nitrate-limited plants may increase net productivity through retention of nitrogen that would otherwise be lost to herbivory.
Response of an insect herbivore to host plants grown in carbon dioxide enriched atmospheres
TLDR
It is suggested that feeding by herbivores on the leaves of C3 plants may increase as the level of atmospheric carbon dioxide rises, and the principal effect on herbivore of increasing the carbon supply of leaves appeared to be reduction of leaf nutrient concentration.
Host-plant protein and phenolic resin effects on larval growth and survival of a butterfly
TLDR
The results agree with prior laboratory investigation that the dietary content of nitrogen and D. aurantiacus leaf resin are major determinants of E. chalcedona larval growth and suggest that the phenolic leaf resin of Diplacus may both deter and inhibit leaf herbivores.
Insect grazing on Eucalyptus in response to variation in leaf tannins and nitrogen
TLDR
It is proposed that the extensive damage observed in many eucalypts is in part related to the high feeding rates maintained by individual larvae, and it is suggested that the low N contents common in EucalyPTus leaves may be responsble.
Effects of variation in Eucalyptus essential oil yield on insect growth and grazing damage
TLDR
Levels of insect attack and yields of leaf essential oils in Eucalyptus vary widely within and among species, and levels of leaf nitrogen, rather than oil content, explained differences in insect feeding and growth.
Stabilization of the Rate of Nitrogen Accumulation by Larvae of the Cabbage Butterfly on Wild and Cultivated Food Plants
TLDR
The growth of P. rapae larvae is limited by the availability of N in their food plants, N budgets for such larvae are of greater ecological significance than energy budgets, and that, in this case at least, natural selection favors the rate (power output) rather than the efficiency of a biological process.
Limiting effects of low leaf-water content on the nitrogen utilization, energy budget, and larval growth ofHyalophora cecropia (Lepidoptera: Saturniidae)
TLDR
The larval rates of consumption of biomass, energy, and nitrogen were the same for all treatments, indicating that leaf water affected larval growth primarily by restricting the efficiency of utilizing these nutrients.
Variation in terpenes and phenolics through leaf development in Hymenaea and its possible significance to herbivory
TLDR
Leaf sesquiterpene resins and phenolic compounds were studied through leaf development in young greenhouse-grown plants of the tropical legume Hymenaea and showed dose-dependent differential effects of three compositional types of Hymanaea defense theory.
Enzyme Activities and Leaf Constituents in Barley Seedlings at Different Nutrient Levels
TLDR
The specific activity of RuBPCase increased at low nutrient levels during development of the second leaf, but not at elevated nutrient levels, therefore, it is likely that RuB PCase protein is degraded less efficiently than other protein.
Carbon/nutrient balance of boreal plants in relation to vertebrate herbivory
TLDR
Fundamental differences between the response of woody plants and graminoids to vertebrate herbivory suggest that the dynamics of browsing systems and grazing systems are qualitatively different.
