Kansas State University scientists and collaborators have developed a new method for studying a variety of streams — including tropical, prairie or forested streams — across continents.
Walter Dodds, university distinguished professor of biology, has led the researchers in creating the Stream Biome Gradient Concept, which is a way to compare streams in different climates and different continents. The concept can improve how researchers study streams worldwide.
"This model will help us understand how to regulate and conserve streams and protect water quality," Dodds said. "It's important to think in broad terms and in the context that people, plants and animals interact with streams. Understanding biodiversity is crucial."
The researchers have introduced the Stream Biome Gradient Concept in the Freshwater Science article "The Stream Biome Gradient Concept: factors controlling lotic systems across broad biogeographic scales."
Other Kansas State University researchers involved include Keith Gido, professor of biology, and Bartosz Grudzinski, visiting assistant professor of geography. Other researchers include Melinda Daniels, an adjunct professor of geography at Kansas State University and associate research scientist at the Stroud Water Research Center in Pennsylvania; and Matt Whiles, professor of zoology at Southern Illinois University.
All of the researchers have studied grassland streams, which share characteristics with other desert and forested streams. They developed the Stream Biome Gradient Concept to take a macrosystems ecology approach, which involves viewing systems on a continental or national scale.
"This concept is important because most previous research has involved temperate, forested streams," Dodds said. "We don't know exactly how that applies to streams in other areas, such as tropical, desert, prairie or tundra streams."
The Stream Biome Gradient Concept can help develop hypotheses to test at STREON sites. STREON — or STReam Experimental Observatory Network — is a 10-year experiment at 10 different aquatic stream sites in a variety of ecosystems. STREON is part of the National Science Foundation-funded National Ecological Observatory Network, or NEON.
"We're hopeful that this work will help people develop a broader and more comprehensive view of the way that stream ecosystems function," Dodds said. "Stream research is getting more mature and focused on large-scale questions. It's a natural progression to think in the largest possible terms and link our conceptual research to a scale where people interact with aquatic habitats."
The researchers received funding support from the National Science Foundation, the Konza Long-Term Ecological Research program and the International Grasslands Center.

Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects
A global team of computer scientists and engineers have developed an innovative technique that more completely reconstructs challenging 3D objects. An ancient...
Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
