View Resource How many species are there? Determining species richness

One of the simplest questions an ecologist can ask about a site is how many species live there. The answer is important for basic researchers and managers alike, but can be deceptively hard to...

View Resource How Much Water Do We Use?

This short film presents the one of the basic concepts of a hydrologic cycle, a water budget. How much water is there? Where it is and how does it move. For example, how does land use effect the...

View Resource Investigating the Evolutionary Adaptations that have Enabled Plants to Survive in a Diversity of Habitats

During this exercise students will explore plant diversity in a greenhouse facility to investigate the evolutionary adaptations that have allowed plants to survive in a diversity of habitats....

View Resource Issues in Ecology, Issue 04: Biodiversity and Ecosystem Functioning

In this report, biodiversity and its relevance to the ecosystems that support humanity is discussed. Ecosystem functioning is defined as the collective activities of all biota within an ecosystem...

View Resource Issues In Ecology, Issue 13: A Synthesis of the Science on Forests and Carbon for U.S. Forests

Forests play an important role in the U.S. and global carbon cycle, and carbon sequestered by U.S. forest growth and harvested wood products currently offsets 12-19% of U.S. fossil fuel emissions....

View Resource Issues in Ecology, Issue 16: The Role of Landscape Connectivity in Planning and Implementing Conservation and Restoration Priorities

Many conservation efforts focus on protecting and enhancing connectivity to offset the impacts of habitat loss and fragmentation on biodiversity conservation, and to increase the resilience of...

View Resource Issues in Ecology, Issue 17: Ecological Dimensions of Biofuels

The promise of biofuels as a renewable, environmentally friendly energy source has driven a worldwide expansion in their production. However, many questions remain about how to produce biofuels...

View Resource Issues in Ecology, Issue 18: Climate Change and U.S Natural Resources: Advancing the Nation's Capability to Adapt

Climate change is affecting land, water, and biodiversity in a variety of ways. While managing ecosystems and resources by relying on an expected set of climate conditions may have worked in the past...

View Resource Pathways to Scientific Teaching, Chapter 3a of 7: Practicing scientific inquiry: what are the rules?

Ecologists attempt to establish general principles from a vast range of organizational, spatial, and temporal scales (Belovsky et al. 2004). The process of developing generalities in ecology...

View Resource Pathways to Scientific Teaching, Chapter 3d of 7: Lyme disease: a case about ecosystem services

One way to help students develop critical thinking skills is to focus on problems or cases where they are challenged to deal with real data and experiences (Bransford et al. 2004). Both problem-based...
