The Guide-Dog approach : a methodology for ecology

In ecology the central problem is not the lack of theory or the lack of data but the lack of research able to link them systematically and critically. The description and analysis of such an integrated research process is the focus of the present study. Our approach is called the Guide-Dog approach, because we hope that it is able to guide all those who are blinded or perplexed by the increasing technical sophistication and fragmentation of modern science

A comprehensive network of measuring stations to monitor climate change

The atmospheric CO2 concentration and temperature have been rather stable at the time scale of millennia, although rather large variations have occurred during longer periods. The extensive use of fossil fuels and destruction of forests have recently increased the atmospheric CO2 concentrations. Temperature and circulation of water on the globe are reacting to the increase in the atmospheric CO2 concentration. Mankind urgently needs knowledge on the present climate change and on its effects on living nature. We propose that a network of comprehensive measuring stations should be constructed, utilizing modem technology to provide documentation of the climate change and data for research related to it. To be able to cover spatial and temporal variations, a hierarchy of stations is needed
