In this activity, learners create a freshwater ecosystem in a large plastic bottle. Learners cut and prepare bottles, then fill with water, aquatic plants, snails and fish. Learners observe their mini-ecosystem over time to see what changes--such as the color of the water, the water temperature, plant growth, and behavior and/or population of the snails or fish. The activity serves as a model for larger freshwater ecosystems such as ponds, lakes, rivers, streams, wetlands, reservoirs and groundwater. (less)

Global Freshwater Crisis, Spring 2011

For the first time in history, the global demand for freshwater is overtaking its supply in many parts of the world. The U.N. predicts that by 2025, more than half of the countries in the world will be experiencing water stress or outright shortages. Lack of water can cause disease, food shortages, starvation, migrations, political conflict, and even lead to war. Models of cooperation, both historic and contemporary, show the way forward. The first half of the course details the multiple facets of the water crisis. Topics include water systems, water transfers, dams, pollution, climate change, scarcity, water conflict/cooperation, food security, and agriculture. The second half of the course describes innovative solutions: Adaptive technologies and adaptation through policy, planning, management, economic tools, and finally, human behaviors required to preserve this precious and imperiled resource. Several field trips to water/wastewater/biosolids reuse and water-energy sites will help us to better comprehend both local and international challenges and solutions. (less)

Over the course of several lessons, this lesson plan deals with the consequences of damming in the Grand Canyon area. Students act as scientists investigating the damming of the Colorado River by the Glen Canyon dam and experimental flooding that took place in 1996. They then write a proposal as to whether or not more experimental flooding should be done on the area considering the ecological effects. This topic has great potential for an Earth Systems Science class, as the consequences of damming affect climate, ecosystems, sedimentation/erosion, and water quality. On this Starting Point page, users can find learning goals, teaching notes and tips, teaching materials, assessment hints and references and resources dealing with this exercise. It also describes the context in which the lesson is best used. (less)

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)

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)
