View Resource Do Antbirds Help or Hinder Army Ants?

In this activity, students examine the nature of the interaction between army ants and ant-following birds. Ant-following birds benefit from the relationship by staying just ahead of the ants and capturing prey animals that are disturbed by the ants. While early studies suggested that the birds' foraging might in turn benefit the ants, it is possible that the birds remove prey that the ants would...

View Resource Investigating the footprint of climate change on phenology and ecological interactions in north-central North America

The ecological questions in this exercise are: 1) Have long-term temperatures changed throughout Ohio? 2) How will these temperature changes impact plant and animal phenology, ecological interactions, and, as a result, species diversity? This exercise is designed to give students experience working with large datasets and to allow them to use real ecological data to evaluate long-term...

View Resource 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...

View Resource Long-term Response of an Arctic River Community to Phosphorus Fertilization

With this TIEE Data Set, students assess effects of phosphorus addition on algae, moss, mayflies, and arctic grayling fish in the Kuparuk River, in the foothills of the North Slope of Alaska. Data were taken over 15 years at the Arctic Long Term Ecological Research (ARC LTER) site at the Toolik field station. Phosphorus was added to the river as an experiment to study the effects of nutrient...

View Resource Issues in Ecology, Issue 05: Biotic Invasions

This report is an introduction to exotic species invasions. An exotic species becomes invasive, when it proliferates unchecked across the region in which it was introduced. The transformation from immigrant to invader and how humans act as dispersal agents is explained. Attributes of invaders, effects on native community, global ecological and economic consequences, prevention, and long term...
