Global Temperature Change in the 21st Century
In this TIEE dataset, students address the question of how global global temperatures change during the 21st century, and how these changes vary geographically, seasonally, and depending upon future human activities.
Students consider how to detect trends in large data sets against a background of variation. They use output from global climate models to examine projected climate change during...

Metabolic ecology: How do body size and temperature affect nutrient cycling rates?
In this TIEE dataset, students answer the question of whether nutrient cycling (excretion) rates of fish in lakes scale with body size and temperature as predicted by The Metabolic Theory of Ecology.
Students use data on the nitrogen and phosphorus excretion rates of fish to test hypotheses related to metabolic ecology.

Demographic vital rates and population growth: an introduction to projection matrices and elasticity analysis
In this TIEE dataset, students address the question of how changes in demographic vital rates influence the rate of population growth.
Students learn how projection matrices and elasticity analysis can be applied to a case-study exploring loggerhead sea turtle (Caretta caretta) conservation and population dynamics. Students are first introduced to the concept of vital rates and population...

Nitrogen biogeochemistry of headwater catchments underlain by discontinuous permafrost
In this TIEE data set, students answer the question of what influences flux of nitrogen from catchments underlain by discontinuous permafrost.
Students work with a large dataset describing nitrogen dynamics in the Caribou-Poker Creeks Research Watersheds, small watersheds in the boreal forest that are underlain with various extents of permafrost cover. Students use spreadsheet and graphics...

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...
