Historical Impacts on River Fauna, Shifting Baselines, and Challenges for Restoration

The decimation of aquatic wildlife through overexploitation is usually perceived as a ... (more)

The decimation of aquatic wildlife through overexploitation is usually perceived as a marine phenomenon, yet it has also been common in freshwater ecosystems. Fish and other aquatic animals were superabundant when Europeans first arrived in North America and Australia, and were intensively exploited soon after. Contemporaneously, the construction of barriers in rivers increasingly prevented many species from migrating. Populations usually crashed as a result. Natural resource managers have not fully considered the ecological impacts of the devastation of these species to the environmental degradation that we see today, yet these impacts are likely to be pervasive. Nor have resource managers embedded the role of these species in river restoration. We argue that the functions of these depleted stocks need to be considered and perhaps reestablished if river restoration efforts are to be successful. The establishment of freshwater protected areas may be the most effective way to do this. (less)

In this case study activity, students will examine the complex issues that result from human use of ecologically sensitive areas. The students will investigate these issues from the point of view of their major/career path. This example page is part of the Starting Point collection and was adapted from the Lifelines Online case study. Users can access information about the exercise's learning goals, context for use, teaching notes and tips, teaching materials, assessment ideas, references and topics covered. (less)

This report addresses the conservation of freshwater ecosystems within the United States. A comparison of the pre-settlement and current conditions of U.S. freshwater resources is provided. Requirements for maintaining freshwater ecosystem physical and biotic components, such as flow patterns, sediment/organic inputs, temperature, light, chemical/nutrient conditions, and plant/animal assemblages are discussed. Freshwater ecosystem management case studies on the Colorado River, the Great Lakes, and South Florida are presented. The report also elaborates on the need to balance human use against needs of freshwater ecosystems. Issues in Ecology is an ongoing series of reports designed to present major ecological issues in an easy-to-read manner. This Issue summarizes the consensus of a panel of scientific experts based on the information that was current and available at the time of its publication in 2003. (less)

In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater. This resource explains the relationship between water density and salinity as well as how this phenomenon relates to water displacement. It also explains how large ships float on water and includes a chart of some famous historical ship sizes. This resource also includes the flood safety tip "Turn Around, Don't Drown." (less)
