View Resource Leaves as Thermometers

Plant morphology reflects evolutionary solutions to environmental constraints. In this experiment, students use this principle to predict the climate at their site. They collect and measure a set of traits on local tree leaf samples during the first meeting. At the following meeting(s), they pool their data and are introduced to a global database of climate and leaf morphology. In groups, they...

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 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 Seedling Growth of Wisconsin Fast Plants (Brassica rapa) in Field Environments

In this Experiment, students investigate the effects of ecological factors on the growth of Wisconsin Fast Plants, also known as rapid-cycling brassica (Brassica rapa L.). Treatments could include light, wind, herbivory, fertilizer, or insecticides. Variables to be measured could include growth (height, number of leaves, leaf area) or reproduction (number of flowers). Wisconsin Fast Plants have...
