It includes all the plants, animals, microorganisms, soil, water, and air in a specific area, along with the energy flows and nutrient cycles that sustain life. Ecosystems can be terrestrial (land ...

And because nitrogen availability often limits the primary productivity of many ecosystems, large changes in the availability of nitrogen can lead to severe alterations of the nitrogen cycle in ...

Satellite data have given us broad pictures of the living biosphere that can be used to determine the total amount of production, carbon, and energy that cycles through ecosystems (Figure 1).

Resulting global and regional changes in climate, material flows and biogeochemical cycles, disturbance regimes, and biodiversity loss have detrimental effects on the very ecosystem services that ...

The feeding relationships between organisms in an ecosystem can be seen in food chains. Sampling allows us to measure the abundance and distribution of these species. In this video, Greg Foot ...

This has altered the food webs and nutrient and energy cycles of ecosystems across the Earth. In the UK, much of the temperate deciduous forest has been removed for farming and to provide room for ...

Wetlands are ecosystems, in which water is the primary ... invasive species and climate change. This vicious cycle of wetland loss, threatened livelihoods, and deepening poverty is the result ...

A change in any of these fluxes could have wide-ranging impacts on ecosystems and our climate. The IAEA Environment Laboratories apply nuclear and isotopic techniques to better understand the carbon ...
