A 4DEE Introduction to wetlands: Basic principles, online mapping, and field identification
This lesson focuses on basic principles and identification of wetlands, which are valuable and productive ecosystems in the landscape. It consists of two files that complement each other. This first is a Powerpoint presentation that provides basic principles about wetlands. The second is a set instructions for a laboratory in which students learn how to locate wetlands using online mapping,...

Resources to Help You to Prepare a Course in Plant Diversity
The extensive (2.4 gig) resources available on OSF (see link) are intended to help young faculty members develop a course on plant diversity. They can be used in whole or in part to jump start a course. They include both lecture and laboratory materials, as well as homework, quizzes, and exams. These materials were developed over the course of more than 15 years and have been extensively tested in...

Impacts of Introduced Species: Interspecific Competition, Predation, and Other Species Interactions
Due to increasing global connectivity, global biotic interchange has been escalating, leading to species introductions in regions in which they are not indigenous. Most of these species do not establish and/or do not cause significant impacts, but a small proportion do and can have positive or, more often, negative ecological, economic, and cultural impacts. These species often interact with...

Comparisons of Mycorrhizal Properties from Two Host Tree Species
In this lab experiment, students learn about ectomycorrhizal (ECM) fungal properties associated with two host tree species to better under understand symbioses in general and gain experience using soil sampling and mycorrhizal field methods. Students will learn in more depth about terms and concepts related to symbioses (e.g. mutualisms, coevolution, host specificity) and about specific...

Teaching Exponential and Logistic Growth in a Variety of Classroom and Laboratory Settings
Ecology and conservation biology contain numerous examples of
populations growing without bounds or shrinking towards extinction. For these
populations, the change in the number of individuals generally follows an
exponential curve. On the other hand, limited resources may keep population
numbers in check and help maintain the population at the environment's carrying
capacity. These...
