Harnessing an invasive fish species sounded like a promising conservation tool to help reverse the destruction wreaked by zebra mussels on endangered native mollusks in the Great Lakes -- except that it won't work, says an ecologist.
Researchers show the link between exposure to pharmaceutical contaminants and consumption of fresh produce grown in reclaimed wastewater-irrigated soil. A new study shows that eating vegetables and fruits grown in soils irrigated with reclaimed wastewater exposes consumers to minute quantities of carbamazepine, an anti-epileptic drug commonly detected in wastewater effluents.
People boating and fishing on the Chesapeake last year kept noticing something they don’t often see — clear water.
In celebration of Earth Day, Penn State Extension Educator, Jim Clark, helped to organize the PA CleanWays of McKean County, an affiliate of Keep Pennsylvania Beautiful, successful highway collection on Saturday, April 23, 2016.
Harmful algal blooms dangerous to human health and the Lake Erie ecosystem--such as the one that shut down Toledo's water supply for two days in 2014--could become a problem of the past. Scientists have reported on approaches to reduce harmful algal blooms on Lake Erie.
Friday, April 22, 2016, will be the 46th year for the annual “Earth Day” event. This event has encouraged individuals and communities to organize illegal dump cleanups, tree planting events, and recycling projects. Cleaning up your environment will beautify the earth, but it also will go a long way to protect important groundwater resources flowing under our feet.
The economic and ecological impact of invasive species in the Great Lakes has been dramatically underestimated, research suggests. In fact, according to researchers, a single non-native species in a single inland lake has racked up $80 million to $163 million in damage.
A new method to track how wetlands in Eastern Washington behave seasonally has been developed by scientists, which will also help monitor how they change as the climate warms.
Homes in rural and suburban areas often rely on private wells for the household water supply and on-lot septic systems for wastewater management. A homebuyer may not notice problems with these essential systems prior to purchase without proper inspections.
GroupGAP is a new food safety certification option that will increase opportunities for the entire industry to supply and buy GAP-certified produce. This robust certification process addresses certain challenges in complying with food safety audits, and meets the demands of the retail, food service, and institutional buying community. The GroupGAP Audit Program will begin April 4, 2016.
Strategic planting of trees on floodplains could reduce the height of flooding in towns downstream by up to 20 percent, according to a study by an international team of scientists.
The National Oceanic and Atmospheric Administration (NOAA) and the National Sea Grant College Program have awarded Sea Grant College status to Penn State based on the strength of Pennsylvania Sea Grant, a research and outreach program operated by Penn State Erie, The Behrend College. The designation reflects a sustained commitment to managing marine and coastal resources across the Commonwealth, including the Lake Erie, Delaware River and Susquehanna River watersheds.
Dangerous nitrate levels in drinking water could persist for decades, increasing the risk for blue baby syndrome and other serious health concerns, according to a new study.
Penn State Extension Water Resources Educator, Jim Clark, presented information on safe drinking water for private water supply owners at the Women in Agricultural Conference in Wellsboro, PA, in Tioga County, on March 23rd.
As Pennsylvania renews efforts to clean the state's waterways and the Chesapeake Bay, Penn State's College of Agricultural Sciences is helping to craft a strategy in which farmers spearhead clean-water initiatives.
Pennsylvania contains thousands of natural and man-made ponds and lakes but surveys by Penn State Extension have found that 77% of pond owners report problems with leaks, water quality, overabundant plant growth, fisheries management, or nuisance wildlife. More recently, algae blooms that release toxins harmful to animals and humans (called Harmful Algae Blooms or HAB’s) have become a common issue.
In 1993, the United Nations General Assembly designated March 22 as the first World Water Day. And with good reason – without water, we’d be nothing. Just dust. Water is one of the most common substances on earth, and one of the most vital; it’s a tremendously valuable resource, yet one we squander and pollute prodigiously.
New research shows that hormones found in birth control pills alter the genes in fish, which can cause changes in their behavior.
Until now, the link between rising water temperatures and higher mortality rates in aquatic animals was a bit of a chicken-and-egg situation. Are they dying because they're unable to absorb enough oxygen from the water? Or are they not absorbing enough oxygen because the warm water is killing them in a different way? A team of ecologists has answered this question in a new article: warm water speeds up the animals' metabolic need for oxygen to such an extent that it causes them to suffer from fatal respiratory distress.
Nature has its own economy, with trading as dynamic as that of any stock exchange. To cope with nutrient deficiencies in their respective habitats, certain plants, animals and fungi have evolved partnerships by which they can swap resources. In a new study, researchers analyze how nutrient pollution can negatively impact important ecological relationships.
