Relative importance of drought, soil quality, and plant species in determining the strength of plant-herbivore interactions

Original language description

Although studies on plant–herbivore interactions comparing different plant species are common, little is known about the importance of environmental conditions in determining variation in herbivory within single plant species. This study assessed the effects of experimentally manipulated nutrient and water availability on plant palatability, and compared these differences with differences among species. The extent to which these patterns can be explained by leaf toughness and specific leaf area was also investigated. Six plant species from the subfamily Carduoideae and four free-living leaf chewing invertebrates were used in the study. Herbivore preferences were significantly affected by soil nutrients and water regime and varied among plant as well as herbivore species. Generally, herbivores preferred watered plants and plants from nutrient-poor soil. The effects of soil nutrients and water regime differed between the plant and herbivore species. The differences between the plant species were greater than those between the environmental treatments. Differences at both levels could be partly explained by leaf toughness and specific leaf area. Leaf toughness, in particular, turned to be an important predictor indicating that herbivores preferred species with softer leaves, and species from wetter conditions with reduced leaf toughness. The environmental conditions in which plants are growing have significant effects on plant palatability. Between-species comparisons thus need to pay attention to this variation. Future studies may consider how the effects of current conditions interact with conditions of plant origin to predict possible effects of changes in environmental conditions on the intensity of plant-herbivore interactions.
