This complex theme deals primarily with interactions between organisms and the environmental factors that impact them, but to a greater extent between individual inanimate environmental factors.

Populations of marine fish may lose genetic diversity even if fishing stops while there are still several million individuals – a number previously assumed to be enough to preserve a diverse gene pool.
Losing the diversity of key genes can render a population less productive and unable to adapt when faced with challenges such as global warming, pollution or changes in predators or prey. Rare genetic variation of little importance today might be the key to adaptability in the future, accordin
Generating rainfall for deserts using wind power and seawater is the subject of a new research project.
The idea involves the installation at sea of specially designed wind turbines. The turning motion of the rotors would be harnessed to pump seawater along the turbines’ hollow blades. The water would then be forced out through slits as a fine spray. These drops would evaporate, with salt falling back into the sea and a cloud of water vapour drifting inland, increasing the probabilit
In an effort to stabilize climate and slow down global warming, Livermore scientists along with a team of international researchers have evaluated a series of new primary energy sources that either do not emit or limit the amount of carbon dioxide released to the atmosphere.
Possible candidates for primary energy sources include terrestrial, solar and wind energy; and solar-power satellites; biomass; nuclear fission; nuclear fusion; fission-fusion hybrids and fossil fuels from which carbon h
Models of Larch budmoth outbreaks in the European Alps may eventually show scientists how to model a variety of disease and insect eruptions that rely on a combination of enemy, host and spatial movement to decimate populations, according to a team of ecologists.
“We use theoretical models to help understand the spatial component in these outbreaks and to predict how spatial spread occurs,” says Dr. Ottar N. Bjornstad, assistant professor of entomology and biology at Penn State. “With local
The rapid increase of nitrogen falling from the sky as a result of fossil-fuel combustion and crop fertilization, combined with carbon stored in Earths soils, could change the rate of the greenhouse gas, carbon dioxide, rising into the atmosphere, according to a new study.
Scientists believe about 300 times more carbon is stored in soils than is being put in the atmosphere in the form of C02, according to biology Assistant Professor Alan Townsend of the University of Colorado at Bould
The ozone layer is thinning and we do not yet know to what extent future ozone losses will be affected by climate change, or what impact this will have on human health.
For this reason, the European Research Commissioner Philippe Busquin today welcomed the start of the first phase of the VINTERSOL (Validation of International Satellites and Study of Ozone Loss) campaign, composed of national and EU projects. VINTERSOL will be closely co-ordinated with the SAGE III Ozone Loss and Valid
