Phenotypic plasticity is considered the major means by which plants cope with
environmental heterogeneity. Although ubiquitous in nature, actual phenotypic plasticity is …

The global nitrogen cycle has been greatly perturbed by human activities resulting in
elevated nitrogen deposition in many parts of the world. The threat nitrogen deposition …

Although it is widely acknowledged that a plant's tolerance of herbivore damage depends on
resource availability in the plant's environment, there is no consensus on whether higher …

The science of finding, testing and releasing herbivores and pathogens to control invasive
plant species has achieved a level of maturity and success that argues for continued and …

Nitrogen (N) deposition has increased substantially since the second half of the 20th century
due to human activities. This increase of reactive N into the biosphere has major …

All living organisms are linked through trophic relationships with resources and consumers,
the balance of which determines overall ecosystem stability and functioning. Ecological …

Abstract Effects of increased N deposition, caused by agricultural practices and combustion
of fossil fuels in traffic and industry, have been studied in detail for soil and water chemistry …
