Abstract

Genotypic variation of monoterpenoid yield and composition in Satureja douglasii was shown by growth of clonal transplants under uniform conditions. Differentiation of monoterpenoid yield was correlated with light intensity and degree of herbivory along transects. High-yielding genotypes occurred under low light, high herbivory conditions, whereas low-yielding genotypes occurred in high light, low herbivory conditions. Differentiation of monoterpenoid composition was more weakly correlated with herbivory and light intensity than was yield. There was also some evidence for seasonal variations of yield.

Bottom-up effects of woodland eutrophication: Interacting limiting nutrients determine herbivory frequency in northwestern Patagonia
2022, Science of the Total Environment
Citation Excerpt :
However, canopy cover was still relevant to mediating herbivory patterns of B. microphylla, since individuals located under high canopy cover showed higher levels of herbivory (Z = 18.8, p < 0.01; Table S1, Fig. 4c). Despite a lack of a clear general pattern, increased herbivory in shaded microhabitats has been found in other research (Lincoln and Langenheim, 1979; Shure and Wilson, 1993; Muth et al., 2008). This preference for shaded microhabitats by herbivorous arthropods could be due to i) lower predation risks and ii) lower stressful abiotic conditions (e.g., more stable temperatures, higher humidity).
Nutrient enrichment disrupts plant–animal interactions and ecosystem functioning globally. In woodland systems, the mechanisms of bottom-up turnover on plant–herbivore interactions remain understudied. Here, we performed a full-factorial field experiment to evaluate the interactive effects of nutrient addition (nitrogen, phosphorus, and/or potassium) on the assemblage of foliar herbivores and the interaction frequency with Berberis microphylla, a dominant shrub species in Patagonian woodlands. Additionally, we assessed whether these effects could be mediated by changes in vegetative traits and microhabitat characteristics (i.e., canopy cover) that may ultimately influence the foraging behavior of herbivores. The addition of nitrogen reduced the herbivory frequency by 41%, yet this effect was diluted in the presence of potassium. We found no effects of phosphorus addition. Our results suggest that the impact of multiple nutrient additions (N and K) on herbivory patterns could be mediated by changes in two important foliar traits, leaf size and leaf density. This study shows how multiple nutrient addition can change the magnitude of antagonistic plant–animal interactions in woodlands. Since herbivory by arthropods has a relevant role in net primary productivity, our results highlight the importance of buffering human-driven woodland eutrophication to maintain important ecological functions (e.g., herbivory) associated with antagonistic plant–animal interactions and avoiding ecosystem dysfunction.
Influence of phytochrome on leaf monoterpene variation is Satureja douglasii
1998, Biochemical Systematics and Ecology
Phytochrome influenced monoterpene variation in mature leaves of Satureja douglasii in a chemotype-dependent manner. Phytochrome significantly increased the concentrations (mg g^-1 leaf dry weight) of camphor, pulegone and carvone and the yield (total amount mg g^-1 leaf dry weight) in the pulegone and carvone chemotypes. However, phytochrome did not influence monoterpene concentrations nor yield in the bicyclic or isomenthone chemotypes. The phytochrome action in the pulegone type is a low fluence response, whereas in the carvone type it is both a low and a very low fluence response. However, statistically, the composition (percent of total monoterpenes) that defines the chemotypes was not significantly influenced by phytochrome and supports other studies suggesting genetic control of the chemotype composition. The chemotypes tend to occur in a particular light environment, although one occurs across a wide range of them. The chemotype-dependent phytochrome response for monoterpene variation may result from adaptation to the light environments where the chemotypes usually occur.
Effect of hostplant genotype and predators on iridoid glycoside content of pupae of a specialist insect herbivore, Junonia coenia (Nymphalidae)
1997, Biochemical Systematics and Ecology
Two field experiments assessed the effects of hostplant genotype, presence or absence of predators, and type of predator on chemical content of pupae of the Buckeye butterfly, Junonia coenia (Nymphalidae). When fed Plantago lanceolata (Plantaginaceae), J. coenia larvae sequester two iridoid glycosides, aucubin and catalpol, which are retained into the pupal stage. In the first experiment, it is found that hostplant genotype significantly affected iridoid glycoside content of pupae, but although the predatory stinkbugs (Podisus maculiventris: Pentatomidae) caused the larvae to alter their foraging behavior, pupal iridoid glycoside content was not influenced by the presence or absence of the predators. In the second experiment, it is found that the kind of predator present had an effect on chemical defense of pupae: pupae exposed as larvae to stinkbugs had a higher proportion of catalpol than pupae exposed as larvae to wasps, Polistes fuscatus (Vespidae). Furthermore, pupae from both experiments contained higher proportions of catalpol than that available in the plants on which larvae fed. Therefore, the conditions under which herbivorous larvae develop, such as hostplant genotype eaten and type of natural enemies present, can affect their chemical content.
Genetic and environmental contributions to variation in leaf mono- and sesquiterpenes of Heterotheca subaxillaris
1989, Biochemical Systematics and Ecology
Field and greenhouse experiments were performed to measure genetic and environmental contributions to variation in the leaf mono- and sesquiterpenes of Heterotheca subaxillaris. Under greenhouse conditions, plants from a nitratevariable habitat (abandoned peach orchard) exhibit greater phenotypic variation in response to nitrate availability than plants from a continuously nitrate-poor environment (coastal sand dune). A genetic contribution to variation in volatile terpenes was measured only in the nitrate-variable orchard habitat. These results suggest that the magnitude of both genetic variation and phenotypic plasticity in volatile terpene production can differ between populations and may increase with greater environmental heterogeniety in the resources which affect terpene metabolism.
Geographical variation in the monoterpenes of Valeriana officinalis Leaf
1989, Biochemical Systematics and Ecology
The variation in terpene composition of the leaf essential oil was studied in three populations of Valeriana officinalis L. subsp, collina. These populations grow in Italy in environmentally very different areas. Our examination of geographically and ecologically distant populations has provided evidence for substantial Iocal intrasubspecific differentiation. Statistical treatment of chemical data revealed two distinct chemical varieties of subspecies collina.
Leaf resin variation in Copaifera langsdorfii: Relation to irradiance and herbivory
1988, Phytochemistry
The influence of irradiance and herbivory on intraspecific patterns of leaf resin variability was investigated for the leguminous tree Copaifera langsdorfii in a Brazilian woodland. An irradiance experiment showed that seedlings in full sun had significantly higher leaf resin yield than in shade (6% full sun), supporting expectations based on plant metabolism. On the other hand, saplings growing under natural conditions had higher resin yields in shade (6% full sun) than in full sun—thus contradicting metabolic predictions. Herbivory by an oecophorid leaf tier was also higher in the shaded than in the full sunlit saplings. Since other factors, such as leaf specific weight, soil nitrogen and soil moisture, were found not to influence leaf resin yield in the two irradiance regimes, it was concluded that the higher herbivory in the shade could have selected for the higher leaf resin yield there.
