  author={Jerry M. Melillo and A. David McGuire and David W Kicklighter and Berrien Moore and C. Vorosmarty and Annette Schloss},
A process-based model was used to estimate global patterns of net primary production and soil nitrogen cycling for contemporary climate conditions and current atmospheric C02 concentration. Over half of the global annual net primary production was estimated to occur in the tropics, with most of the production attributable to tropical evergreen forest. The effects of C02 doubling and associated climate changes were also explored. The responses in tropical and dry temperate ecosystems were… 

Impact of climate change on grassland production and soil carbon worldwide

Combined climate change and elevated CO2 increased production and reduced global grassland C losses to 2 Pg, with tropical savannas becoming small sinks for soil C.

Comparing global models of terrestrial net primary productivity (NPP): global pattern and differentiation by major biomes

Annual and seasonal net primary productivity estimates (NPP) of 15 global models across latitudinal zones and biomes are compared. The models simulated NPP for contemporary climate using common,

Sensitivity of primary production to precipitation across the United States.

For the first time, an empirically-derived map of ecosystem sensitivity to climate across the conterminous United States is produced, showing that annual primary production values were most sensitive to precipitation and aridity in dryland and grassland ecosystems.

Biogeochemical cycling in tropical forests

Increased inputs of greenhouse gases have altered the composition of the atmosphere over the past 150 years (IPCC, 2001, 2007), resulting in shifts in temperature and precipitation around the globe.

Net primary productivity in the terrestrial biosphere: The application of a global model

DEMETER, a new process-based model of the terrestrial biosphere, is used to simulate global patterns of net primary productivity (NPP). For the modern climate, NPP and vegetation biomass are

The Potential Effects of Elevated Co2 and Climate Change on Tropical Forest Soils and Biogeochemical Cycling

Tropical forests are responsible for a large proportion of the global terrestrial C flux annually for natural ecosystems. Increased atmospheric CO2 and changes in climate are likely to affect the

Carbon balance in the tundra, boreal forest and humid tropical forest during climate change: scaling up from leaf physiology and soil carbon dynamics

Carbon exchange by the terrestrial biosphere is thought to have changed since pre-industrial times in response to increasing concentrations of atmospheric CO 2 and variations (anomalies) in

The global terrestrial carbon cycle

There is great uncertainty with regard to the future role of the terrestrial biosphere in the global carbon cycle. The uncertainty arises from both an inadequate understanding of current pools and

Transient climate change and net ecosystem production of the terrestrial biosphere

In this sensitivity study, we have applied the Terrestrial Ecosystem Model ((TEM) version 4.1) to examine the responses of terrestrial ecosystems to transient changes in atmospheric CO2 concentration

Net primary and ecosystem production and carbon stocks of terrestrial ecosystems and their responses to climate change

Evaluating the role of terrestrial ecosystems in the global carbon cycle requires a detailed understanding of carbon exchange between vegetation, soil, and the atmosphere. Global climatic change may



Potential Net Primary Productivity in South America: Application of a Global Model.

Seasonal patterns of NPP in South America are correlated with moisture availability in most vegetation types, but are strongly influenced by seasonal differences in cloudiness in the tropical evergreen forests.

Global climate change and US agriculture

Agricultural productivity is expected to be sensitive to global climate change. Models from atmospheric science, plant science and agricultural economics are linked to explore this sensitivity.

It is concluded that there is insufficient information to predict accurately the response of primary production to climate change, and mechanistic models of production compound the errors associated with individual process responses with uncertainties surrounding interaction and scaling up.

Interactions between carbon and nitrogen dynamics in estimating net primary productivity for potential vegetation in North America

We use the terrestrial ecosystem model (TEM), a process-based model, to investigate how interactions between carbon (C) and nitrogen (N) dynamics affect predictions of net primary productivity (NPP)

Sensitivity of terrestrial carbon storage to CO2-induced climate change: Comparison of four scenarios based on general circulation models

The potential impacts of CO2-induced climate change on terrestrial carbon storage was estimated using the Holdridge Life-Zone Classification and four climate change scenarios derived from general


More studies are required to be able to accurately assess the effects of carbon dioxide, because the authors have relatively poor records of the functional and structural response of any ecosystem through time.

Regional hydrologic and carbon balance responses of forests resulting from potential climate change

The projected response of coniferous forests to a climatic change scenario of doubled atmospheric CO2, air temperature of +4 °C, and +10% precipitation was studied using a computer simulation model

Grassland biogeochemistry: Links to atmospheric processes

Regional modeling is an essential step in scaling plot measurements of biogeochemical cycling to global scales for use in coupled atmosphere-biosphere studies. We present a model of carbon and

A model to predict global patterns in vegetation physiognomy was developed from physiological considera- tions influencing the distributions of different functional types of plant. Primary driving

State-of-the-Art of Models of Production-Decomposition Linkages in Conifer and Grassland Ecosystems.

There are several models based on dominant processes that are well enough understood for the predictions of those models to be taken seriously, and these include steady-state models, which cannot be used to predict transients caused by climate change.
