Drought impacts on above–below ground interactions: Do effects differ between annual and perennial host species?
Staley, Joanna T.; Mortimer, Simon R.; Morecroft, Michael D.. 2008 Drought impacts on above–below ground interactions: Do effects differ between annual and perennial host species? Basic and Applied Ecology, 9 (6). 673-681. 10.1016/j.baae.2007.10.006Full text not available from this repository.
Root herbivores can have a positive or negative effect on the abundance and/or performance of foliar phytophages. In addition, abiotic factors such as drought can either strengthen or weaken this effect, depending on the system under investigation. One explanation for these varying responses lies in differences in the physiological response of host plants to drought and root herbivores. Here, the impacts of root phytophages on a leaf-mining species feeding on annual and perennial plant species (four Sonchus species) were compared. The responses of plants and leaf-miners to drought and root herbivore treatments were not related to whether the host plant was an annual or perennial. However, where root feeders did affect foliar phytophage performance, this occurred only under a drought treatment, demonstrating the potential for climate change to alter the outcome of plant-mediated interactions.
