Researchers have found that larval fish exposed to microplastic particles during development displayed changed behaviors and stunted growth which lead to greatly increased mortality rates. The researchers discovered that larval perch that had access to microplastic particles only ate plastic and ignored their natural food source of free-swimming zooplankton.
Upgrading wastewater treatment plants can dramatically reduce a municipality’s nitrogen footprint
Ah, summertime…. picnics, barbecues, outdoor activities… unfortunately, also a time to be bugged by mosquitoes and their potential to carry diseases.
Even though amphibian populations are declining sharply worldwide, there is no smoking gun to indicate a cause and thus no simple solution to halting or reversing these declines.
Hydraulic fracturing, a widely used method for extracting oil and gas from otherwise impenetrable shale and rock formations, involves not only underground injections composed mostly of water, but also a mixture of chemical additives. Researchers have now set out to discover whether the degradation of these chemicals in agricultural soil are affected by co-contamination.
Diane Oleson and Amy Galford, Penn State Educators and Deborah Kronsteiner, Penn State Master Watershed Steward presented the “Stop Aquatic Hitchhikers” activity during the Bay Day event held at Gettysburg College on May 10, 2016. Sixty seven youth and seven teachers learned about the different aquatic invasive species (AIS) found in Pennsylvania.
A new report from the U.S. Environmental Protection Agency (EPA) and National Oceanic and Atmospheric Administration (NOAA) looks at how local planners and decision-makers can incorporate the effects of a changing climate into their efforts to manage stormwater runoff.
Water is essential to all life on earth. When the quality of water is impaired every living organism is impacted. The problems associated with Lake Erie are examples of how agricultural practices, naturally occurring events, and other human activities can have an impact on water quality.
The Center for Watershed Protection, Inc. has released a new guide for citizen science groups and watershed organizations across the nation to take a role in finding and eliminating sources of harmful bacteria in their communities.
Pause for a moment and consider your nearest stream. Do you know where it goes? Chances are, if you live in one of the 41 counties covering central Pennsylvania, that water finds its way to the Susquehanna River and the Chesapeake Bay.
Penn State Extension Educator, Jim Clark and Penn State Watershed Specialist, Bryan Swistock presented a class on pond management for pond owners in North Central Pennsylvania on May 26, 2016, at the North Fork Dam Recreation Area in Potter County, PA.
Most U.S. homes are full of familiar household products with an ingredient that fights bacteria: triclosan. Most of the triclosan is removed in waste water treatment plants. However, a U.S. Geological Survey found the antibacterial in nearly 58% of freshwater streams. What does that mean for the food and soil irrigated with water from streams? As triclosan breaks down, it can turn into other harmful compounds. The breakdown of triclosan produces more effective hormone disruptors.
Plastic accounts for nearly eighty per cent of all waste found in our oceans, gradually breaking down into smaller and smaller particles. New research investigates how nanosized plastic particles affect aquatic animals in different parts of the food chain.
Last week, the governor of Colorado signed a bill legalizing rain barrels. Before then, the capture and use of rainwater, even on so small a scale, was illegal in Colorado.
Pause for a moment and consider your nearest stream. Do you know where it goes? Chances are, if you live in one of the 41 counties covering central Pennsylvania, that water finds its way to the Susquehanna River and the Chesapeake Bay. This week, June 5-11, marks the first-ever Chesapeake Bay Awareness Week. It’s a time to celebrate the Bay watershed’s diverse waterways and landscapes, rich history, immense economic impact, and the aesthetic and recreational offerings it and all of its local waters provide to the 18 million people who live in its watershed.
The overall health of Chesapeake Bay improved in 2015, according to scientists. The largest estuary in the nation scored a C (53 percent) in 2015, one of the three highest scores since 1986. Only 1992 and 2002 scored as high or higher, both years of major sustained droughts.
Many landowners, regulators and citizen scientists are interested in simple tools to assess the health of streams. The latest webinar in the Penn State Water Resources Extension series focused on a new stream health assessment tool called First Investigation of Stream Health or “FISH”.
Private water supplies in nine Pennsylvania counties underserved by water-quality educational programs and water testing will be the focus of two new Penn State Extension projects aimed at helping well owners detect and remediate lead and other common contaminants.
Protein discovery is important first step in harnessing power of green algae for agriculture. Algae may hold the key to feeding the world's burgeoning population. Because they are more efficient than most plants at taking in carbon dioxide from the air, algae could transform agriculture. If their efficiency could be transferred to crops, we could grow more food in less time using less water and less nitrogen fertilizer. New work reveals a protein that is necessary for green algae to achieve such remarkable efficiency.
Newly published research shows water yields from unmanaged forested watersheds in the southern Appalachian Mountains declining by up to 22 percent a year since the 1970s. Changes in water yield were largely related to changes in climate, but disturbance-related shifts in forest species composition and structure over time also played a role. The study findings have implications for managing the forest composition of watersheds to ensure water supply under future climate change.
