In this exercise, students design and perform an experiment that helps them investigate the effects of habitat complexity on biodiversity in aquatic communities. In particular, students will glue...
This case study is divided into two parts to explore the development of the drinking water supply for New York City. First, a brief history on the evolution of the water supply system is presented. ...
This exercise links a daily activity in your students’ lives to its biological sources. By connecting your students’ lives to biodiversity in a concrete way, the biodiversity crisis becomes present...
This exercise has students use the IUCN species “Red List” to become familiar with the current status of particular species around the world and to explore the likely consequences to humanity and the...
In this exercise students gain hands on experience by conducting observations in the field. In groups students identify and record all the plants found in a sample plot. Using pooled data from the...
Ecosystem services associated with invertebrates might include soil aeration by earthworms, pollination by bees or habitat provision by coral reefs. However, we do not typically list provision of...
Species interactions can occur along a continuum from mutualism to parasitism and can evolve to different points along this continuum over time. This classroom activity explores this concept by...
As informed citizens, students should be able to understand and interpret the value of a working ecosystem and the cascading implications of disturbances. We use a case study to introduce students to...
River discharge couples terrestrial ecosystems with oceanic ecosystems. Fluctuations in river discharges from drought or flood events can have significant effects on coastal ecosystems.
Students learn how drought affects aquatic ecosystem services such as freshwater provision and habitat preservation by critically analyzing the current problems in the Sacramento-San Joaquin Delta....
