U. Iowa Water Quality Class Brings Mississippi River Lessons To Life

Learning about things in a classroom can be fun, but book learning can only take students so far. Some need hands-on experience to really make the lessons stick. That principle is incredibly important for science courses, where paper-based information and tests just don’t hold a candle to getting out in the field to study. In one real-world example of this method in practice, a teacher at the University of Iowa’s Lucille A. Carver Mississippi Riverside Environmental Research Station (LACMRERS) runs a summer field class that gets down into the nit and grit of water quality sampling on the Mississippi. The connections that it makes for students are just too valuable to pass up, he says.

Inland Lake Monitoring

Chapter Overview: Lake Management Types of Lakes Limnological Concerns A Real-Time Solution Typical Inland Lake Monitoring System Monitoring Location Data Management Quality Assurance Recommended Equipment Why Monitoring Matters Lakes and ponds of any size are complex ecosystems with numerous inputs and outputs that can impact water quality in subtle or drastic ways. Whether the lake is man-made, with a focus on recreational fishing and watersport, or a habitat naturally formed from ancient glacial or tectonic activity, understanding the hydrological parameters that contribute to a lake’s health is important for proper management.

Landmarking Study Sheds Light On Managing Asian Carp Invasion Risk

In ecology, “landmarking” is defined as the tendency of insects and animals to congregate in locations that make it easier for them to find mates. The sites that they flock to are typically easy to find and special — that is, there aren’t many sites like them elsewhere in the ecosystem. For insects like butterflies, landmarking is showcased through their flights to the tops of trees or mountains where they can be more easily spotted by members of the opposite sex. Humans are said to be landmarking when they go to bars or other social venues where high numbers of potential mates will be present. Fish, in spite of swimming around in waters that look similar, do it too, by keying in on water flows and temperatures only they can sense.

New Tech Aids Lake Erie Sturgeon Tracking

Efforts to study prehistoric sturgeon in Lake Erie are underway in Buffalo Harbor, according to the Buffalo News . The New York State Department of Environmental Conservation and U.S. Fish and Wildlife Service are involved in the work that centers on tracking the fish known as “living fossils.” Key questions that biologists are investigating include sturgeon population changes, migration patterns and life cycle habits. They are also interested in locating the fish’s prime spawning sites in the lake. To track the fish, around three dozen acoustic telemeters have been placed along the bottom of Buffalo Harbor, as well as other tracking equipment in the Buffalo and Niagara Rivers. Additional telemeters have been placed across Lake Erie all the way to the Canadian shoreline.
