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 …

Tree mortality rates appear to be increasing in moist tropical forests (MTF s) with significant
carbon cycle consequences. Here, we review the state of knowledge regarding MTF tree …

Elemental stoichiometry constitutes an inherent link between biogeochemistry and the
structure and processes within food webs, and thus is at the core of ecosystem functioning …

This chapter addresses the biogeochemical cycles of carbon dioxide (CO2), methane (CH4),
and nitrous oxide (N2O). The three greenhouse gases have increased in the atmosphere …

Although it is well established that soils are the dominating source for atmospheric nitrous
oxide (N2O), we are still struggling to fully understand the complexity of the underlying …

The availability of carbon from rising atmospheric carbon dioxide levels and of nitrogen from
various human-induced inputs to ecosystems is continuously increasing; however, these …

China is experiencing intense air pollution caused in large part by anthropogenic emissions
of reactive nitrogen,. These emissions result in the deposition of atmospheric nitrogen (N) in …

Global change is impacting forests worldwide, threatening biodiversity and ecosystem
services including climate regulation. Understanding how forests respond is critical to forest …

Because the capability of terrestrial ecosystems to fix carbon is constrained by nutrient
availability, understanding how nutrients limit plant growth is a key contemporary question …

This study explored the response of NO3–-N bioreduction to Cr (VI) stress, including
reduction efficiency and the pathways involved (denitrification and dissimilatory nitrate …
