A press release for an article addressing the benefits of dry river beds. This article also explores how human manipulation of seasonal water sources for land use disrupts the natural cycle necessary...
In this activity, students work with a dataset to investigate energy balance in animals that have different feeding behaviors (diurnal/nocturnal) and diets (e.g., carnivore/detritivore).
In this Experiment, students make impressions of leaf stomata (using clear nail polish) and test a hypothesis of their choice about how leaf stomata density might vary under different environmental...
This Issue focuses on a research article by Blaustein and Johnson (2003) that was published in Frontiers in Ecology and the Environment. The article discusses amphibian deformities, which may be...
In this laboratory exercise, the following issues are examined: 1) why neither predators nor prey go extinct when there is a long period of nonrenewal of the prey population 2) the effects of...
In this TIEE experiment, students investigate how ambush predators such as the common ambush bug (Phymata americana) or the common crab spider (Misumena vatia) influence the foraging behavior of...
The image shows predation (piscivory) by a Great Blue Heron (Ardea herodias) in a wetland complex Great Blue Herons typically forage for fish, frogs, and other animals at the edge of a body of water...
