The globalization of N deposition: ecosystem consequences in tropical environments
Human activities have more than doubled the inputs of nitrogen (N) into terrestrial systems globally. The sources and distribution of anthropogenic N, including N fertilization and N fixed during fossil fuel combustion, are rapidly shifting from the temperate zone to a more global distribution. The consequences of anthropogenic N deposition for ecosystem processes and N losses have been studied...
متن کاملNitrate Deposition following an Astrophysical Ionizing Radiation
It is known that a gamma ray burst (GRB) originating near the Earth could be devastating to life. The mechanism of ozone depletion and subsequent increased UVB exposure is the primary risk, but models also show increased nitrification culminating in nitric acid rainout. These effects are also expected after nearby supernovae and extreme solar proton events. In this work we considered specifical...
متن کاملToxic Response of Mosquito Culex Quinquefasciatus (Diptera: Culicidae) to some Agricultural Pesticides (Butachlor and Pertilachlor)
Background: The expansion of herbicide used in aquatic ecosystems as well as in terrestrial if is not properly controlled may produce harmful effects on freshwater fisheries. Residue limits of these agricultural chemicals in tropical fishery waters should be established. The aim of this study was to determine the acute toxicity of butachlor and pertilachlor as potential dangerous herbicides to ...
متن کاملGlobal assessment of nitrogen deposition effects on terrestrial plant diversity: a synthesis.
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 experiments for N deposition effects and thresholds for terrestrial plant diversity protection across a latitudinal range of main categories of ecosystems, from arctic and boreal systems to tropical forests. Current th...
متن کامل113-119 Matson.p65
Human activities have more than doubled inputs of nitrogen (N) to terrestrial ecosystems worldwide (1). Until recently, most of this increase was focused in the developed regions of the world. With fertilizer consumption (2), fossil-fuel emissions (3), and biomass burning (4) rapidly increasing in less developed regions, sources and distribution of anthropogenic N now occur globally (5), as doe...
