Differential herbivory in contrasting environments is commonly explained by differences in plant traits. [] Key Method We measured alkaloids, phenolics, trichomes, leaf thickness and water content in the same plants sampled for herbivory. We conducted a multiple regression analysis to estimate the relationship between herbivory and each plant trait accounting for the effect of correlated traits, thus identifying which trait(s) better explain(s) the differential herbivory on A. chilensis.
Light and sex interplay: differential herbivore damage in sun and shade in dioecious Mercurialis perennis
TLDR
The combined effects of light environment and plant sex on natural herbivore damage and plant traits in the dioecious understory forb Mercurialis perennis on Mt. Kopaonik found that factors defining risk of consumption were related to plant morphological traits and nutritive value rather than to chemical defenses.
Effect of light environment on intra-specific variation in herbivory in the carnivorous plant Pinguicula moranensis (Lentibulariaceae)
TLDR
Evaluated the effect of spatial variation in light environment (sunny, shade and full-shade sites) on the pattern of leaf herbivory and florivory of the carnivorous plant Pinguicula moranensis, finding that plants’ overall probability of leaf damage was high and the probability of florvory was similar among sites.
Herbivores Modify Selection on Plant Functional Traits in a Temperate Rainforest Understory
TLDR
It is provided the first demonstration that natural herbivory rates can change the strength of selection on plant ecophysiological traits, that is, attributes whose main function is resource uptake.
Population-specific responses to light influence herbivory in the understory shrub Lindera benzoin.
TLDR
It is suggested that herbivores could affect evolution of photosynthetic plasticity in L. benzoin, which would limit the fitness value of this protective response to light-induced photoinhibition.
Interactive effects of light environment and herbivory on growth and productivity of an invasive annual vine, Persicaria perfoliata
TLDR
Results support the plant vigor hypothesis and suggest that high weevil densities in the sunny habitats favored by P. perfoliata can suppress plant growth, negating the resource advantage to plants growing in the sun.
Plant diversity has contrasting effects on herbivore and parasitoid abundance in Centaurea jacea flower heads
TLDR
Parasitism rates, mainly of the abundant chalcid wasps Eurytoma compressa and Pteromalus albipennis, increased with plant species or functional group richness in both transplants and potted plants, suggesting that direct effects of plant diversity are most important.
Shade tolerance and herbivory are associated with RGR of tree species via different functional traits.
TLDR
The findings suggest that shade and herbivores may differentially contribute to shape RGR of tree species through their effects on different resource-uptake functional traits.
Attenuation of the Jasmonate Burst, Plant Defensive Traits, and Resistance to Specialist Monarch Caterpillars on Shaded Common Milkweed (Asclepias syriaca)
TLDR
A mechanistic basis for the attenuation of induced plant resistance in low resource environments is provided, with light-mediated impacts on jasmonate-induction being stronger for latex exudation than cardenolides.
Global patterns of insect herbivory in gap and understorey environments, and their implications for woody plant carbon storage
TLDR
Results are consistent with the idea that low resource availability – and not temperature – limits insect herbivore activity in forest understoreys, especially in the tropics, and suggest the selective influence of Insect herbivory on late-successional tree species may have been over-estimated.
Difference in defense strategy in flower heads and leaves of Asteraceae: multiple-species approach
TLDR
Differences in five traits that are thought to affect the intensity of herbivory (C, N, P, water, and total phenolic contents) are investigated using wild individuals of Asteraceae to find significant differences in flower head traits and weak phylogenetic signals in the defensive traits imply that the traits the authors measured evolved frequently.

Increased per capita herbivory in the shade: Necessity, feedback, or luxury consumption
TLDR
In this system, greater natural field herbivory in shade habitats relative to high light habitats, despite similar herbivore abundances is consistently observed; differences in Herbivory are therefore most likely attributable to different per capita impacts of herbivores across environments.
Plant ontogeny and chemical defence: older seedlings are better defended
TLDR
The results corroborate species-specific patterns of seedling herbivory observed in field studies, and offer some explanation for the relatively high sensitivity to herbivore attack frequently observed for relatively young seedlings compared with their older conspecifics.
Intraspecific variation in growth, defense and herbivory in Dialium guianense (Caesalpiniaceae) mediated by edaphic heterogeneity
TLDR
Understanding of how edaphic heterogeneity can determine intraspecific variation in the relationship of plants with their herbivores is contributed and the underlying mechanisms promoting such influence are evaluated.
The herbivorous insect communities of open and woodland bracken: observations, experiments and habitat manipulations
TLDR
The degree of shading of the host plant has pronounced, but variable effects on the distribution of bracken herbivores, apparent that processes determining the distributions and abundances of each species are both complex and idiosyncratic.
The influence of light and nutrients on foliar phenolics and insect herbivory
TLDR
The results support earlier studies suggesting that slow- growing, shade-tolerant species tend to have higher levels of phenolics and experience lower levels of herbivory than fast growing, Shade-intolerance species, and similar levels of dogwood phenolics in most microenvironments are indicative of the relatively high photosynthetic efficiency of this species in reduced light environments.

TLDR
Folivorous mammals do less damage than insects or pathogens but have evolved to cope with the high levels of plant defenses and, along with insect herbivores, may contribute to the maintenance of tree diversity.
