The primary reason is that the wetlands prevent a surfeit of nutrients from reaching our oceans and lakes. A study from Halmstad University shows, in addition, that wetlands have contributed to saving several frog and bird species from the “Red List”–a list that shows which species are at risk of dying out in Sweden.
In the latest update, five of the nine red-listed bird species that breed in wetlands–including the little grebe and the little ringed plover–could be taken off the list. Yet another bird species was moved to a lower threat category. As regards batrachians, four species–among them the European tree frog–have been taken off the list, and two species have been moved to a lower threat category.Great effect on biological diversity
During the 19th and 20th centuries, the amount of wetlands in Sweden decreased drastically: almost all original wetlands in agricultural areas have disappeared through drainage and land reclamation. This has affected many of the plants and animals that depend on these types of environments.An inexpensive way to reduce eutrophication
The study shows that creation of wetlands is a cost-effective to catch the nutrients.
“It’s a very effective way of purifying the water. It’s less expensive than constructing treatment plants, and in addition it contributes to biological diversity,” Prof Weisner says.
The research study, which is a compilation of previous studies in the field, was written by Stefan Weisner of Halmstad University and John Strand of the Agricultural Society of Halland, and has been published in Ecological Engineering.

A biological and energy-efficient process, developed and patented by the University of Innsbruck, converts nitrogen compounds in wastewater treatment facilities into harmless atmospheric nitrogen gas. This innovative technology is now being refined and marketed jointly with the United States’ DC Water and Sewer Authority (DC Water). The largest DEMON®-system in a wastewater treatment plant is currently being built in Washington, DC.
The DEMON®-system was developed and patented by the University of Innsbruck 11 years ago. Today this successful technology has been implemented in about 70...
Permanent magnets are very important for technologies of the future like electromobility and renewable energy, and rare earth elements (REE) are necessary for their manufacture. The Fraunhofer Institute for Mechanics of Materials IWM in Freiburg, Germany, has now succeeded in identifying promising approaches and materials for new permanent magnets through use of an in-house simulation process based on high-throughput screening (HTS). The team was able to improve magnetic properties this way and at the same time replaced REE with elements that are less expensive and readily available. The results were published in the online technical journal “Scientific Reports”.
The starting point for IWM researchers Wolfgang Körner, Georg Krugel, and Christian Elsässer was a neodymium-iron-nitrogen compound based on a type of...
In the Beyond EUV project, the Fraunhofer Institutes for Laser Technology ILT in Aachen and for Applied Optics and Precision Engineering IOF in Jena are developing key technologies for the manufacture of a new generation of microchips using EUV radiation at a wavelength of 6.7 nm. The resulting structures are barely thicker than single atoms, and they make it possible to produce extremely integrated circuits for such items as wearables or mind-controlled prosthetic limbs.
In 1965 Gordon Moore formulated the law that came to be named after him, which states that the complexity of integrated circuits doubles every one to two...
