These events were accompanied by reductions in ecosystem productivity, the researchers wrote, in addition to wildfires, air pollution and agricultural losses.

Ancient forests that are allowed to grow have net ecosystem productivity of zero on average over the long term.

Other benefits such as increased water availability, reduced energy demands, and greater ecosystem productivity may also occur in specific regions over the short or long - term.

I believe that biodiversity has inherent merit regardless of its role (or lack thereof) in ecosystem productivity or function.

These changes are likely to have significant impacts on marine ecosystem productivity globally, with uncertainties in projections of NPP using six mainly IS92a - based scenarios narrowing to an increase of between 0.7 % and 8.1 % by mid-century -LRB-?

Eventually such soils become depleted and ecosystem productivity declines rapidly.

Pieces of this coupling have been introduced previously: that forest loss / gains perturb the surface energy budget sufficiently to influence global climate [15,25]; and that remote, large - scale climate patterns, such as El Nino Southern Oscillation (ENSO), impact ecosystem productivity [37,38].

Commonwealth water provided as barrage flow exported significant volumes of salt, nutrients and phytoplankton that supported ecosystem productivity in the Coorong and the export of salt at the Murray Mouth.

In their model herbivory is greatest in relatively unproductive environments, with predation more important and the impact of herbivory reduced as ecosystem productivity increases.

Insects also play a critical role in nutrient cycling and decomposing organic materials, which helps ensure ecosystem productivity.

«Major changes in northeast Pacific marine ecosystems have been correlated with phase changes in the PDO; warm eras have seen enhanced coastal ocean biological productivity in Alaska and inhibited productivity off the west coast of the contiguous United States, while cold PDO eras have seen the opposite north - south pattern of marine ecosystem productivity.»

The study revealed that when unpredictable weather patterns create alternating wet and dry years, ecosystem productivity declines — mostly because grasses diminish, which allows shrubs to flourish.

These climate indices are correlated with population dynamics [8], [9] because they reflect atmospheric circulation patterns which regulate large scale oceanographic processes and ecosystem productivity [10], [11].

«Then we compare the variability in ecosystem productivity, which we also obtain from satellite data, against the variability in the important climate variables.»

Tropospheric or ground - level ozone is a greenhouse gas and air pollutant that, at high levels, is detrimental to human health and crop and ecosystem productivity.

Aside from fall foliage and its economic importance to many areas, the research has broad implications for predicting growing seasons, agricultural productivity and ecosystem productivity, Medvigy said.

Ecosystem productivity, one factor considered responsible for regulating plant biodiversity, has long been a subject of debate.

Researchers have studied how the green world hypothesis holds up under different levels of ecosystem productivity, called net primary production.

On the other hand, ecosystem productivity had either regained or exceeded its normal level a year after a climate event, regardless of plant diversity, showing that biodiversity has no effect on ecosystem resilience, at least on annual timescales.

How can the atmospheric sciences community facilitate access to ozone metrics necessary for quantifying the impact of tropospheric ozone on human health, crop and ecosystem productivity and climate?

Our current research focuses on how changes in emissions of these compounds or their precursors influence climate, how changes in climate influence both emissions and atmospheric lifetimes of these compounds, and how changes in their abundance in the atmosphere influences society by affecting human health and ecosystem productivity.

Impacts of large - scale and persistent changes in the MOC are likely to include changes to marine ecosystem productivity, fisheries, ocean carbon dioxide uptake, oceanic oxygen concentrations and terrestrial vegetation [Working Group I Fourth Assessment 10.3, 10.7; Working Group II Fourth Assessment 12.6, 19.3].
