View Resource Biodiversity Responses across a Gradient of Human Influence

To investigate how species, communities, and habitats change over the rural-urban (or pristine to human-dominated) gradient students conduct a series of biological inventories, field measurements, taxonomic keying out, natural history classifications, landscape classifications, statistical analyses, and a literature review. Each laboratory session will be geared towards one or several of these...

View Resource An Assessment of Assemblage Nestedness in Habitat Fragments

This experiment illustrates how ecological theory can help conserve native species in a fragmented landscape. It is germane to units on biogeography, human impacts on ecosystems, landscape ecology, conservation, and restoration. During the first lab, the instructor introduces the process of habitat fragmentation, the degree to which species in species-poor assemblages are proper subsets of...

View Resource Pathways to Scientific Teaching, Chapter 5b of 7: Learning through peer assessment

Ecological succession is driven by disturbance, both natural and human-induced, and change occurs at multiple scales, both temporal and spatial. Understanding the mechanisms involved in succession requires the integration of many ideas, some of which may contradict students’ belief that succession is only a unidirectional and linear model. The notion of ecosystems as static, or as eventuall...

View Resource The Invasive Grass-Fire Cycle in the U.S. Great Basin

Students will exercise critical thinking skills to form a hypothesis on how cheatgrass alters fire behaviors. Students will analyze data and answer questions based on their interpretation of field-based data and satellite data. Using this information, students will collaborate to create maps and graphs. This activity is included in Volume 8 of Teaching Issues and Experiments in Ecology...

View Resource Order Up! Ecological Succession at Table Rock State Park in Pickens, South Carolina

Students are given photos of different phases of ecological succession that are from Table Rock State Park in Pickens, South Carolina. Using their knowledge of ecological succession, students arrange the photos in chronological order of the phases of succession.
