4DEE Activity - Estimation of Animal Population Size
This activity is a lab exercise that teaches students how to estimate animal population size. It covers two main techniques: Mark and Recapture (MR) and Capture Per Unit Effort (C/UE). The MR methods include the Lincoln-Petersen and the Schumacher-Eschmeyer approaches. Three approaches for the C/UE method are also included. This exercise is aligned with the Ecological Society of America's Four...

Effects of Intraspecific Competition on Plants
This lab exercise examines the effect of density on the survival and growth of plant populations. Students examine a variety of parameters in experimental populations of radish plants grown at different densities. They evaluate their findings against the Law of Final Constant Yield and the Reciprocal Yield Law. This exercise follows the Four Dimensional Ecology Education (4DEE) framework...

How do Lake Ecosystems Change with Increases in Dissolved Organic Matter (DOM) and Reduced Water Clarity? Long-term investigations in lake ecology
Water quality is a significant issue affecting our lakes. While the effects of nutrients on water quality has received much attention, light availability also has strong effects on water quality in lake ecosystems. Light availability has been changing in many lakes with changes in water clarity. Many lakes are undergoing “browning”, where waters become darker and less transparent due to increases...
