Ecohydrology of Terrestrial Ecosystems

BioScience, 2010
Water controls the dynamics of terrestrial ecosystems directly, as a resource for the biota, and indirectly, as a driver for abiotic processes on the Earth's surface, in the atmosphere, and belowground. The biota, in turn, modulate several hydrological processes and the rate of the water cycle.

Arctic terrestrial ecosystem contamination

Science of The Total Environment, 1992
Limited data have been collected on the presence of contaminants in the Arctic terrestrial ecosystem, with the exception of radioactive fallout from atmospheric weapons testing. Although southern and temperate biological systems have largely cleansed themselves of radioactive fallout deposited during the 1950s and 1960s, Arctic environments have not ...

Manipulatable Terrestrial Ecosystems

Ecology, 1964
Terrestrial ecosystems common to rock outcrops as they occur throughout most of the world posses unique characteristics which enable them to be experimentally manipulated. A means for establishing outcrop communities under controlled conditions is discussed.

Declined terrestrial ecosystem resilience

Global Change Biology
AbstractTerrestrial ecosystem resilience is crucial for maintaining the structural and functional stability of ecosystems following disturbances. However, changes in resilience over the past few decades and the risk of future resilience loss under ongoing climate change are unclear.

Terrestrial Ecosystem Changes

2006
Models are used to estimate potential physical and biological impacts, efficient adaptations, and residual damages from climate change. The contributors cover a broad array of climate change impacts on affected market sectors (including water supply, agriculture, coastal resources, timber, and energy demand) as well as ecosystems and biodiversity.

Terrestrial ecosystems: Antarctica

Polar Biology, 1994
Scientific reasons for the study of terrestrial ecosystems in the Antarctic are outlined together with brief descriptions of the maritime and continental zones. Opportunities for ecological research are highlighted in a consideration of the terrestrial environments, biological colonisation, organism survival and community development.

Terrestrial Ecosystem Ecology

2011
Human activities impact the environment and modify the cycles of important elements such as carbon and nitrogen from local to global scales. In order to maintain long-term and sustainable use of the world's natural resources it is important that we understand how and why ecosystems respond to such changes.

Terrestrial ecosystem inertia

Nature Geoscience, 2009
Some components of the climate system continue to adjust long after atmospheric greenhouse-gas levels have stopped changing. A coupled climate–vegetation model shows that forests can be committed to die-back or expansion before change is observed.

Nitrogen saturation of terrestrial ecosystems

Environmental Pollution, 1988
Nitrogen saturation, in the sense that nitrogen additions to an ecosystem lead to losses of the same order of magnitude, is analyzed as an interplay between a plant subsystem and a soil subsystem. The plant system is defined by its nitrogen productivity, which allows calculations of the maximum amount of nitrogen that can be held in, and the maximum ...
