Sentences with phrase «forest ecosystem model»

This research will fuel the development of a first - of - its - kind tropical forest ecosystem model that extends from the bedrock to the top of the forest canopy.

Not exact matches

Model simulations can always be improved by testing predictions against field data collected from different ecosystems, and Sulman and Phillips are doing just that: investigating how roots influence soil decomposition and protected forms of carbon in forests that vary in the composition of tree and microbial communities.

[W. R. L. Anderegg et al, Pervasive drought legacies in forest ecosystems and their implications for carbon cycle models]

There, he used computer modeling and field data to elucidate how forest ecosystems store and recycle carbon and to compare alternative theories for species coexistence.

Wang, S., R.F. Grant, D.L. Verseghy, and T.A. Black, 2002: Modelling carbon dynamics of boreal forest ecosystems using the Canadian land surface scheme.

EcoMOD will offer links between multiple forms of representation to help connect visual models to dynamic representations of ecosystem interactions in a simulated forest setting.

EcoPlanet is the first company to successfully industrialize bamboo, providing a proven model of successful ecosystem restoration at scale, converting thousands of acres of degraded land back into fully functioning ecosystems, reversing the negative effects of global climate change and providing thousands of marginalized people with the potential to change their own lives in areas of the world where few opportunities exist, all while reducing deforestation and forest degradation through the provision of a sustainable alternative fiber for timber and fiber manufacturing industries.

«In almost all of our mathematical models of ecosystems and forests, drought is generally treated like a light switch,» says William Anderegg, an assistant professor at the University of Utah, and lead author on the study: «When drought stress is present, the switch is flipped and trees grow more slowly and die more often, but as soon as the drought disappears, the switch is flipped back the other way.»

Based on measurements of ecosystem CO2 flux, radiation absorption by plants, crop yields and a model simulating the terrestrial biosphere, a multinational team of researchers has found that during July and August 2003, 500 million tonnes of carbon escaped from the forests and fields across Europe as a result of extreme heat and drought.

Gower and colleagues used the Biome - BGC process model to simulate what is happening in the Boreal Ecosystem - Atmosphere Study (BOREAS) region, which at 1000 km × 1000 km makes up 15 — 20 % of the North American boreal forest.

The regional effects of unexplained factors suggest that the next generation of ecosystem models will need to explore the impacts of forest demography, differences in regional management intensities for cropland and pastures, and other emerging productivity constraints such as phosphorus availability.

Models also suggest that feedback cycles could afflict both the tundra — where scientists fear a massive carbon release — and the Amazon forest ecosystem, which could rapidly dry up, McCarthy noted.

With funding from UNDP Regional Office, ECOTRUST has established a carbon bank modelled as a revolving fund to reduce unsustainable exploitation of forest resources and the decline of ecosystem quality, while diversifying and increasing incomes for rural farm families.

Using simulation models that account for the impact of increased atmospheric carbon dioxide concentrations on temperature and precipitation in the region, scientists at the Hadley Center for Climate Prediction and Research in the UK have forecast significant «die - back» of the Amazon rain forest by mid-century and a virtual collapse of the ecosystem by 2100.
