Interactive effects of defoliation and an AM fungus on plants and soil organisms in experimental legume-grass communities

Article Abstract:

Hokka and coworkers established a 13-week greenhouse experiment based on replicated microcosms to test whether the effects of defoliation on grassland plants and soil organisms depend on plant species composition and the presence of arbuscular mycorrhizal fungi. The results show that defoliation had widespread effects in the experimental systems. The effects on plant growth were invariably negative and those on bacterivorous nematodes invariably positive, most effects on plant C and N content and soil inorganic N concentration varied depending on the plant species present.

The architecture of shrubs after defoliation and the subsequent feeding behavior of browsers

Article Abstract:

Morphological changes in the regrowth architecture of plants may have a long-term effect on the subsequent feeding behavior of herbivores. The hypotheses that mechanical damage to spinescent shrubs may alter the architecture of the regrowth branches, which in turn is predicted to decrease the forage value of the plant to large herbivores, is tested.

Costs of induced volatile production in maize

Article Abstract:

The fitness cost of the production of induced volatiles in maize, Zea mays, is estimated. Results indicate that the costs of induced volatile production in plants are counterbalanced by the benefits as long as the natural enemies of the herbivores are present in the environment.
