News in brief
New test can reveal whether plants have been sprayed:
The National Environmental Research Institute (NERI) has developed a method for determining whether plants have been sprayed with herbicides. The method was developed by NERI senior scientist Helle Weber Ravn, and the institute has filed an international patent application for the method. Among other things the new method will enable differentiation between plants cultivated with the use of pesticides and those cultivated without the use of pesticides, including organic produce. NERI has entered into cooperation with the company Biotech Line A/S and the two partners expect to be able to develop and market a simple test method within the space of a few years.

Arctic waders are fully dependent on local food resources:
According to a recent article in Nature (Vol. 413, p. 794, October 2001) co-authored by National Environmental Research Institute scientist Hans Meltofte, Arctic waders (or shorebirds) obtain the protein they need for egg laying from insects and spiders caught after arrival on the tundra of Northeast Greenland and not, as previously believed, from body reserves accumulated at their staging areas along the coasts of Europe. The finding derives from studies carried out at Zackenberg Research Station in Northeast Greenland and are based on the carbon-13:carbon-12 ratio in the proteins.
