Reservoirs may accelerate the spread of invasive aquatic species, researchers say
Just as disturbance makes a landscape susceptible to invasion by alien plant species, the construction of reservoirs around the globe could be contributing to the accelerating spread of exotic aquatic species, according to a Forum article in the June 2005 issue of BioScience. John A. Havel of Southwest Missouri State University and Carol Eunmi Lee and M. Jake Vander Zanden of the University of Wi...Aggressive aquatic species invading Great Lakes
Foreign species, such as zebra mussels and carp, are invading the Great Lakes and changing the ecology of this vital ecosystem. A study from McMaster University published in the March issue of the Journal of Great Lakes Research suggests that for the round goby, a recently introduced fish species, their ability to wrest territory from native fish plays a key role in their dominance of the Great L...Aquatic plants may hold key to advancing plant disease management
The way aquatic plants respond to plant disease and climate change may have applications for managing land-based agriculture, say plant pathologists with The American Phytopathological Society (APS). According to David Schmale III, Cornell University, Ithaca, NY, many aquatic plants possess unique mechanisms of resistance to microbial attack. "Through further study, plant pathologists may...National Academies advisory: Invasive aquatic species in the Great Lakes
On May 7, a National Research Council committee will hold a meeting in Toronto to gather information on trade in the Great Lakes region and ways to eliminate further introductions of nonindigenous aquatic species into the lakes by vessels traveling the St. Lawrence Seaway. The committee's final report will comment on the strengths and weaknesses of various options and recommend those that seem mo...UBC researchers reveal dwarf aquatic plants' hidden ancestry
A team of UBC researchers has re-classified an ancient line of aquatic plants previously thought to be related to grasses and rushes. The discovery clarifies what may be one of the biggest misunderstandings in botanical history. "It’s a classic case of mistaken identity," says Sean Graham, an associate professor and researcher with the UBC Botanical Garden and Centre for Plant Research in...Taq DNA Polymerase (Thermus aquaticus) from GE Healthcare, formerly Amersham Biosciences

According to a report by the Food and Agriculture Organisation (FAO) of the United Nations and the World Organisation for Animal Health animal species said that domestic and wild birds spread the bird flu virus.// Analysis of the data accumulated since the start of the avian influenza crisis (the end of 2003), cats did not play any discernable role in the transmission of the virus in...Pharmaceuticals May not Pose Major Aquatic Environmental Risks
A Canadian study of high-use drugs released from eight sewage treatment plants indicates that effects on invertebrates, bacteria, and plants// in the aquatic receiving environment are unlikely. The study is published in the latest issue of Environmental Toxicology and Chemistry. The pharmaceutical market is a booming industry. The manufacture of drugs is increasing to match its demand...
