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.
innovations-report offers informative reports and articles on topics such as climate protection, landscape conservation, ecological systems, wildlife and nature parks and ecosystem efficiency and balance.
Habitat fragmentation is a primary threat to amphibians worldwide, and new research suggests one of the reasons why. Experimental evidence for three species shows that fragmentation may hinder the dispersal of juvenile amphibians, which could contribute to population declines.
“Habitat fragmentation is likely to reduce dispersal rates between local populations of these three species,” say Betsie Rothermel and Raymond Semlitsch of the University of Missouri in Columbia in the October issue o
Sudden collapses in many ecological systems are the rule rather than exceptions to the rule. This is shown by Professor Lennart Persson of Umeå University, Sweden, in the latest issue of the scientific journal Proceedings of the National Academy of Sciences. Among other things, the article provides an explanation for the collapses in cod stocks in different parts of the world. Several models have shown that ecological systems can experience catastrophic collapses. On the other hand, th
Driven by precise new satellite measurements and sophisticated new computer models, a team of NASA researchers is now routinely producing the first global maps of fine aerosols that distinguish plumes of human-produced particulate pollution from natural aerosols.

Project Synopsis:
The PEOPLE project involves the monitoring of ambient outdoor and indoor levels of air pollutants as well as measuring population exposure in European capitals. With the selection of benzene as a first pollutant to be measured, EC directive 2000/69/EC is also supported. Benzene is a carcinogenic pollutant to which exposure is associated with the risk of the development of leukaemia.
Brussels and Lisbon have been selected as the first cities for the PEOPLE
To combat urban sprawl and protect wildlife, many communities have set aside land for wildlife corridors linking natural areas to one another.
Public support for these greenways, however, has overshadowed a long-running debate among ecologists about whether they actually achieve their presumed benefits. The debate has been hobbled by a lack of definitive data, with many studies based solely on observations and others only on small-scale experiments, scientists say.

Scientists may soon have a better idea of the potential effects of global warming thanks to the work of Tony O’Hagan, Professor of Statistics at the University of Sheffield.
Scientists already know that global warming will have consequences for the earth but are unsure how mild or severe these effects may be, due to the inaccuracies in their prediction models. Professor O’Hagan’s method will allow scientists to better determine these inaccuracies and has major significance in the world of
