Environmental sensors can measure almost any physical parameter in nature, but sometimes they can overwhelm the science they are supposed to support.
Jason Hill, an assistant professor of engineering at the University of Southern Indiana, wants to create a water level model that will help wetland restorers understand and predict water level fluctuations by studying water loss through the ground and evapotranspiration.
The problem is his next project site has too many variables to measure. So, he’s taking an old fashioned route based on empiricism and water level measurement.
Hill said that conventional techniques for estimating evapotranspiration require site specific micrometeorological data, like solar radiation, wind speed and vapor pressure.Read More
Is eradicating Great Lakes sea lamprey an “impossible dream?” Researchers say no
The sea lamprey’s days in the Great Lakes could be numbered.
That’s according to one researcher who took one of the first scientific looks at the possibility of sea lamprey eradication in the Great Lakes.
So, can you remove enough sea lamprey to make them disappear?
“Well the answer is we already have,” said Michael Jones, emeritus professor of fisheries and wildlife at Michigan State University. “Then there’s the obvious question: Why are they still here?”
While multiple gaps in current management techniques, like sea lamprey poisons called lampricides, could account for sea lamprey’s persistence in the Great Lakes, new technology could help sea lamprey managers eliminate inaccessible populations.Read More
The Shasta crayfish and signal crayfish are two similar looking arthropods on two very different ecological trajectories. As one spreads in abundance, originating in the Pacific Northwest and spreading throughout the world, the other has been reduced to a handful of remaining populations spread throughout one river and its tributaries.
Pacifastacus leniusculus - the signal crayfish - has met few obstacles in its widely successful expansion from the Pacific Northwest southward in California and Nevada, as well as Europe and Japan. By some expert accounts, it has reached invader status. And while invasive species are rarely good for the surrounding food webs, it’s Pacifastacus fortis - the Shasta crayfish - that’s suffered the most at the signal crayfish’s fortune.Read More
