“…An increase in the C: N ratio of leaf material, due to a decrease of leaf % N, has been shown to influence herbivore activity, with insects increasing their consumption of leaf tissue (Lincoln et at., 1986). The C:N ratio of plant litter and roots regulates decomposition processes, witb a reduced litter quality slowing decomposition rates (Melillo, Aber & Muratore, 1982).…”

“…With an enhanced carbon source the growth and activity of the endosymbiont might increase. Furthermore, eievated CO2, might also influence mycorrhiza through (r) the modification of the biota and activity of the rhizosphere by changes in root exudation (Norby et al., 1987), {ii) by changes due to altered carbon to nitrogen ratio (Lincoln, Couvet & Sionit, 1986;Fajer, 1989;Lincoln & Couvet, 1989) and {iii) by the general effect of increased sequestration of carbon to below-ground structures (Curtis et al, 1990). In addition, these changes might in the long term alter the physical and chemical nature of the soil, thereby affecting mycorrhiza.…”

SUMMARYTrifolium repens L. cv. aran was grown for 58 d at ambient (350//mol moi"^) and elevated (700//moi mol"') atmospheric CO^, with and without the arbuscular mycorrhizal fungus Glo?nus mosseae (Nicol. & Gerd.) Gerd. & Trappe cv. YV. Plant biomass, mycorrhizal infeciion, non-structural carbohydrates, C, N and P content were examined. Ele\'ated CO., (a) significantly increased above-and below-ground biomass, (b) decreased specific leaf area and specific root lengtb, (c) decreased tissue "^N and increased tbe C:X ratio, and (d) significantly increased total non-structural carbohydrates. Inoculating T. repens with Glomus mosseae (a) significantly increased abo\ e-and below-ground biomass, (h) increased the total root length and total leaf area, and (c) significantly decreased tissue°o P-Evidence of an increased influence of mycorrhiza on the P nutrition of T. repens at elevated CO^ was found in the 22 "<, increase in leaf total P (P ^ 005) of mycorrhizal plants grown at elevated CO^ compared with nonmycorrhizal plants. No significant interactions were found between CO^ and mycorrhiza treatments.The proportion of T. repens root length colonized by Glomus mosseae was not affected by CO^ concentration. The percentage mycorrhizal infection was 29 % at ambient CO^ and 35 "o at elevated CO^. However, exposure to elevated CO., significantly increased the total mycorrbizal root length from 3-4 to 6-1 m per plant.The results show little evidence that the role of arbuscular mycorrhiza in the growth and nutrition of T. repens would increase if atmospheric CO., were to increase as predicted.

“…Elevated carbon supply can shift the stoichiometry of marine primary producers towards higher C:N and C:P ratios, thereby further decreasing the nutritional quality for herbivores (Urabe et al, 2003;van de Waal et al, 2010). Herbivores can compensate for low levels of essential nutrients in their food by increasing consumption (Lincoln et al, 1986). Surplus carbon can then be removed metabolically, e.g.…”

Understanding the ecological implications of global climate change requires investigations of not only the direct effects of environmental change on species performance but also indirect effects that arise from altered species interactions. We performed CO 2 perturbation experiments to investigate the effects of ocean acidification on the trophic interaction between the brown seaweed Fucus vesiculosus and the herbivorous isopod Idotea baltica. We predicted faster growth of F. vesiculosus at elevated CO 2 -concentrations and higher carbon content of the algal tissue. We expected that I. baltica has different consumption rates on algae that have been grown at different CO 2 levels and that the isopods remove surplus carbon metabolically by enhanced respiration. Surprisingly, growth of F. vesiculosus as well as the C:N-ratio of the algal tissue were reduced at high CO 2 -levels. The changes in the elemental composition had no effect on the consumption rates and the respiration of the herbivores. An additional experiment showed that consumption of F. vesiculosus by the isopod Idotea emarginata was independent of ocean acidification and temperature. Our results could not reveal any effects of ocean acidification on the per capita strength of the trophic interaction between F. vesiculosus and its consumers. However, reduced growth of the algae at high CO 2 -concentrations might reduce the capability of the seaweed to compensate losses due to intense herbivory.

The effects of elevated atmospheric CO 2 concentration on plant-fungi and plant-insect interactions were studied in an emergent marsh in the Chesapeake Bay. Stands of the C 3 sedge Scirpus olneyi Grey. and the C 4 grass Spartina patens (Ait.) Mobl. have been exposed to elevated atmospheric CO 2 concentrations during each growing season since 1987. In August 1991 the severities of fungal infections and insect infestations were quantified. Shoot nitrogen concentration ([N]) and water content (WC) were determined. In elevated concentrations of atmospheric CO 2 , 32% fewer S. olneyi plants were infested by insects, and there was a 37 % reduction in the severity of a pathogenic fungal infection, compared with plants grown in ambient CO 2 concentrations. S. olneyi also had reduced [N], which correlated positively with the severities of fungal infections and insect infestations. Conversely, S. patens had increased WC but unchanged [N] in elevated concentrations of atmospheric CO 2 and the severity of fungal infection increased. Elevated atmospheric CO 2 concentration increased or decreased the severity of fungal infection depending on at least two interacting factors, [N] and WC; but it did not change the number of plants that were infected with fungi. In contrast, the major results for insects were that the number of plants infected with insects decreased, and that the amount of tissue that each insect ate also decreased.
