“…For those herbivores that build constructs, however, host plant choice is likely to depend on a combination of architectural traits, which inXuence the ability of the insects to build the shelter, and plant quality factors, which determine success once feeding proceeds (Lawton 1983;Marquis et al 2002;Wise and Abrahamson 2008). Potentially relevant traits include leaf Xexibility, distance between leaves, distance between twigs, leaf size, leaf density, and branching angle (Marquis et al 2002).…”

Because shelter-building herbivorous insect species often consider structural features of their host plants in selecting construction sites, their probability of attack is likely to be a function of some combination of plant architectural traits and leaf quality factors. We tested the hypothesis that plant architecture, in the form of the number of touching leaves, influences interspecific variation in attack by leaf-tying caterpillars in five species of sympatric Missouri oaks (Quercus). We compared colonization on control branches, in which both architecture and leaf quality were potentially important, with colonization on experimental branches for which we controlled for the effects of architecture by creating equal numbers of artificial ties. Colonization of artificial ties was highly correlated with natural colonization on neighboring control branches, suggesting that leaf quality factors and not architecture influenced interspecific variation in attack by leaf-tying caterpillars. Of the leaf quality factors measured (water, protein-binding capacity, nitrogen, specific leaf area, pubescence, and toughness), nitrogen was the most explanatory. With the exception of white oak, natural leaf tie colonization was positively correlated with nitrogen availability (ratio of nitrogen to protein-binding capacity), and negatively correlated with protein-binding capacity of leaf extracts. Both host plant species and subgenus oak influenced the community composition of leaf-tying caterpillars and the non-tying symbionts colonizing the ties. Host plant differences in leaf nitrogen content were positively correlated with pupal weight of one of two caterpillar species reared on all five host plant species. Thus, interspecific differences in nitrogen, nitrogen availability, and protein-binding capacity of leaf extracts are the best predictors at this time of interspecific differences in attack by leaf-tying caterpillars, in turn affecting their success on individual host plants in the laboratory.

“…Solidago altissima (hereafter Solidago) is a dominant plant species in old-field ecosystems (Schmitz 2003, Abrahamson et al 2005, Schmitz 2008, Wise and Abrahamson 2008Souza et al, in press), across a range of thermal zones in eastern North America, from Florida (average January and July temperatures ¼ 26.68C and 32.38C, respectively) to Maine (average January and July temperatures ¼ 4.28C and 26.68C, respectively), and has significant morphological trait variation shaping ecosystem processes (Crutsinger et al 2006, Crutsinger et al 2008, Crutsinger et al 2009). Additionally, predicted increases in global temperatures range from 1.5-1.98C to 3.4-6.18C, which would raise the average growing season temperature of Solidago up to ;378C in Florida and ;318C in Maine.…”

Abstract. Plant species, and the traits associated with them, can help buffer ecosystems to environmental perturbations. Few studies have examined whether within species variation, both among and within populations, can similarly buffer ecosystems to environmental perturbations, such as climatic warming, across levels of organization. Using a dominant plant species in the eastern US, Solidago altissima, we examined whether genotypes of the same species from both southern and northern latitude populations exhibited differential short-term responses to temperature at the cell, leaf, and plant level. At the cell level we quantified the production of reactive oxygen species (by-product of temperature stress) and total oxygen radical antioxidant capacity (which ameliorates temperature stress by-products). At the leaf and plant levels, we measured CO 2 assimilation. Increasing temperatures had strong negative impacts on plantlevel carbon gain, but weak impacts on cell-level antioxidant capacity. Southern latitude genotypes had greater total antioxidant capacity, but lower leaf-level carbon gain, than did northern genotypes under elevated temperature. At the plant level, northern and southern genotypes exhibited similar declines in carbon gain under elevated temperature, likely because total plant leaf area was higher for southern genotypes than northern genotypes, which compensated for their lower per unit area leaf-level carbon gain. Overall, short-term temperature-induced declines in carbon gain at the plant level may scale to reduce within species variation, both across and within populations, potentially altering ecosystem carbon cycling.

“…Vigorously growing trees can be more attractive to insects (Price 1991;Carr et al 1998;Cornelissen et al 2008, but see e.g. Cornelissen et al 1997) and larger plants may be more easily detected by herbivores than smaller ones (Haysom & Coulson 1998;Campos et al 2006;Wise & Abrahamson 2008). Thus, plant genotypes that increase their growth the most due to warming climate may be at higher risk of herbivore damage than slower growing ones.…”

2016): Susceptibility of silver birch (Betula pendula) to herbivorous insects is associated with the size and phenology of birch -implications for climate warming, Scandinavian Journal of Forest Research, ABSTRACT Susceptibility of trees to herbivorous insects is often associated with the tree growth and phenology, both of which are sensitive to a warming climate. Therefore, changes in these traits may affect the intensity of herbivory on trees in the future. We grew silver birch (Betula pendula) populations differing in their growth and phenology in a common garden experiment, and studied the effect of these plant traits on the leaf herbivory, insect herbivore density and community composition of herbivores in two consecutive years, 2011 and 2012. Differences in size and the timing of growth cessation among the birch genotypes were related to differences in herbivore community compositions and herbivory. In 2011, the most intensive herbivore damage was observed on birch genotypes of small size, late bud burst and early growth cessation, and these genotypes originated from high-latitude populations. The differences among birch genotypes in their susceptibility to herbivore damage may lead to differences in their competitive abilities. While climate warming will affect phenology and growth of plants, our study shows, that it may indirectly affect herbivory and herbivore communities as well. ARTICLE HISTORY
