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.

Scientists from Nepal, Switzerland and Germany was now able to show how erosion processes caused by the monsoon are mirrored in the sediment load of a river crossing the Himalaya.
In these days, it was again tragically demonstrated that the Himalayas are one of the most active geodynamic regions of the world. Landslides belong to the...
A world-class prime systems integrator and electronic systems provider known for its rapid, innovative, and agile technology solutions, Sierra Nevada Corporation (SNC) is currently developing a new space transportation system called the Dream Chaser.

Today, textiles are used for more than just clothes or bags – they are high tech materials for high-tech applications. High-tech textiles must fulfill a number of functions and meet many requirements. That is why the Fraunhofer Institute for Silicate Research ISC dedicated some major developing work to this most intriguing research area. The result can now be seen at Techtextil trade show in Frankfurt from 4 to 7 May. On display will be novel textile-integrated sensors, a unique multifunctional coating system for textiles and fibers, and textile processing of glass, carbon, and ceramics fibers to fiber preforms.
Thin materials and new kinds of sensors now make it possible to integrate silicone elastomer sensors in textiles. They are suitable for applications in medical...
