View Resource Are males cheaper than females? Male and female costs of reproduction

In this TIEE experiment, students investigate the costs of reproduction. In dioecious plants, a female's investment in reproduction is typically much greater than a male's, because while both sexes encounter the basic cost to produce a flower, only females have to allocate energy to seeds, exceeding the energy requirements to produce pollen. This 1-2 week field project tests whether the effects of...

View Resource Using Stream Leaf Packs to Explore Community Assembly

In this TIEE experiment, students will explore functional and taxonomic diversity in a stream ecosystem, learn about food web relationships, and learn about the ways in which abiotic and biotic factors determine what organisms are present in a community. Students will make and install artificial leaf packs in a stream, wait for the leaf packs to be colonized by stream organisms, measure...

View Resource 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.

View Resource 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...

View Resource 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...
