Spraying chemicals can be dangerous to the environment in many ways. But for Floridians, they can contribute to harmful algae blooms and damaging releases along the coast. There are other ways to remove invasive plant species that may not require chemical spraying. James Douglass, an environmental scientist at Florida Gulf Coast University says the other
Carraízo reservoir in Puerto Rico has fallen victim to two of the world’s most invasive aquatic plants: water lettuce and water hyacinth. Often found together, the invasive plants grow at exponential rates, obstruct waterways, clog hydropower plants, and prevent sunlight from penetrating the water’s surface, reducing water quality. The Aqueduct and Sewer Authority began its
In recent years Fox Lake in Wisconsin has responded to a decade of water quality management that has shifted the lake from being turbid with frequent algae blooms to a clearer water condition. This has fostered improved lake use, the return of aquatic plants and a more balanced fishery. One consequence of the water quality
Biologists in Cornwall have found that chemicals released in the ocean from plastic can lead to deformities in marine animals. The study by biologists from the Centre for Ecology and Conservation on Exeter’s Penryn Campus found that plastics in the ocean can release chemicals that cause deformities in sea urchin larvae.

In July, the last known patches of Giant Salvinia, an invasive and aggressive aquatic plant at the Barnett Reservoir in Mississippi, were eliminated. The vegetation was treated with multiple chemicals and then removed, but after six months of Giant Salvinia being absent from the lake, the cleanup team discovered the unwelcomed guest. Apparently a stray
Seagrass meadows are widespread in shallow coastal waters and are involved in trapping and binding sediment particles that form the seabed. These seagrass meadows also provide important ecosystem services and benefits, such as water quality improvement; CO2 absorption; climate change mitigation; sediment production for seafloor and beach stabilization; coastal protection; nursery and refuge areas for
The Okanagan Basin Water Board milfoil program has been so successful over the past five decades. Aquatic weed harvesters used in significant areas with milfoil infestation on Okanagan Lake, British Columbia, Canada are now clear of the invasive plant. Meanwhile, the water board continues to work with the province and environmental consultants to expand existing
More than 25 years ago, biologists in Arkansas began to report dozens of bald eagles paralyzed, convulsing, or dead. Their brains were pocked with lesions never seen before in eagles. Birds were dying at lakes and reservoirs throughout the southeast, and at every lake Susan Wilde, an aquatic ecologist at the University of Georgia, Athens
County legislators are considering providing some type of support to a group trying to get rid of the Eurasian milfoil infestation in Black Lake, New York. The milfoil problem is exacerbated when propellers on boats going through the lake chop it up (prop chop) the and spread its seeds. Legislators debated what methods could stop
Our carbon dioxide emissions are making the oceans more acidic. As we pump carbon dioxide into the atmosphere, a portion dissolves into the world’s oceans. Once there, the carbon dioxide goes through a series of chemical changes that have an acidifying effect on seawater. Trees absorb carbon dioxide from the air and through photosynthesis. Underwater
