The productivity of ecosystems and their capacity to support life depends on access to
reactive nitrogen (N). Over the past century, humans have more than doubled the global …

About one‐third of North America is forested. These forests are of incalculable value to
human society in terms of harvested resources and ecosystem services and are sensitive to …

Atmospheric deposition of inorganic nitrogen is critical to the function of ecosystems and
elemental cycles. During the industrial period, humans have doubled the amount of …

Atmospheric nitrogen (N) deposition is a recognized threat to plant diversity in temperate
and northern parts of Europe and North America. This paper assesses evidence from field …

Atmospheric nitrogen (N) deposition has been shown to decrease plant species richness
along regional deposition gradients in Europe and in experimental manipulations. However …

Aboveground-Belowground Linkages provides the most up-to-date and comprehensive
synthesis of recent advances in our understanding of the roles that interactions between …

We consider the role that key structural traits, such as spinescence, pubescence,
sclerophylly and raphides, play in protecting plants from herbivore attack. Despite the …

Tree decline is a global concern and the primary cause is often unknown. Complex
interactions between fluctuations in nitrogen (N) and acidifying compounds have been …

The Eurasian steppe has long been subject to grazing by domestic ungulates at high levels,
resulting in widespread deterioration of biodiversity and ecosystem services. While …

Human activities have more than doubled reactive nitrogen (N) deposited in ecosystems,
perturbing the N cycle and considerably impacting plant, animal, and microbial communities …
