Aquatic Toxins

A number of algal toxins, including microcystins and anatoxin, can have significant effects on fish, as well as wildlife and human health. Blooms of suspended and periphyton algal populations are commonly observed in many drainages. Eutrophication of waterways can cause overgrowth of algae and potential release of toxic “blooms” or great increases of phytoplankton or diatoms into the aquatic environment. Research into aquatic toxins includes identifying the presence of toxins in water, periphyton and fish tissue and simultaneously conducting histopathological and gene expression analyses of fish tissue to produce a more complete understanding of aquatic toxins and their impacts on fish.

An ecosystem approach to assessing unconventional oil and gas impacts in aquatic ecosystems

The development of unconventional oil and gas (UOG) technology promises economic, societal and national security benefits.  However, technological developments in this field have rapidly outpaced scientific studies on potential environmental effects.  The effects of accidental UOG-related spills on environmental health are not adequately characterized, often occur in already ecological...

Assessing the effects of chloride exposure on aquatic organisms

Increased salinization of freshwater systems is a growing concern, and can be attributed to a variety of factors including climate change, land-use change, agricultural practices, road de-icing, and brines released from fossil fuel extraction.  Effects of increased salinization on aquatic organisms is little understood and may be vastly different among species and among different life stages...
