The incidence of particular skin and liver tumors on white suckers collected from some Wisconsin rivers corresponded to the degree of urban development within the watershed. Further research is needed to understand the relationship between exposure to urban-sourced contaminants and the initiation, promotion, and potential for population-level effects of these tumors.

As a result of the globalization of trade and transport, in the past decades, tens of thousands of species have spread into regions where they were not originally at home. Potentially serious consequences of this include the displacement or extinction of native species and the spread of health risks. Even though trade flows are known to represent an important path for the introduction of invasive species, this fact alone is not enough to explain the observed distribution patterns of species.

The quality of our rivers and lakes could be placed under pressure from harmful levels of soluble phosphorus, despite well-intended measures to reduce soil erosion and better manage and conserve farmland for crop production, a new study shows. The team of international scientists found that increased levels of soluble phosphorus in rivers entering Lake Erie, in the USA, may be linked to conservation measures.

First-ever reconnaissance study documents the off-field transport of nitrapyrin — a nitrification inhibitor applied with fertilizers as a bactericide to kill natural soil bacteria for the purpose of increasing crop yields — to adjacent streams. This study is the first step in understanding the transport, occurrence, and potential effects of nitrapyrin or similar compounds on nitrogen processing in aquatic systems.

The frequencies of occurrence of hundreds of insect species inhabiting streams have been altered relative to the conditions that existed prior to wide spread pollution and habitat alteration, American scientists have discovered. Results were similar for the two study regions (the Mid-Atlantic Highlands and North Carolina), where frequencies of occurrence for more than 70 percent of species have shifted.

The dirt and gravel roads that run through your forest play an important role in the management of your woodlands. A well-maintained road provides safe access for fire control, recreation, timber harvesting, and other forest management activities. However, poorly constructed and maintained access roads often cause severe soil erosion and sedimentation into streams.
