Access Resources for Free

Posted by on .

Welcome to the Life DiscoveryEd Digital Library (LDDL), an online resource portal for biology education in ecology, plant biology and evolution. This project is a partnership of the Ecological Society of America, the Botanical Society of America and the Society for the Study of Evolution, collectively, the Life Discovery Partners. Launched in March 2013, this project was made possible by a major grant from the National Science Foundation. Currently, you will find that most resources are appropriate for undergraduate audiences.

The Life Discovery Partners are committed to bringing quality resources to educators free of charge based on the Creative Commons Attribution 4.0 International (CC BY 4.0) license. Teaching activities, data sets and figure sets on the site are peer-reviewed and accepted for educational use by one of the partners. Other resources such as images and syllabi have been reviewed by a Resource Editor.

View Resource Tree Tender Supplemental Teaching Bundle

The short film Tree Tender (2016) follows a young woman, Gaia, becoming the newest Tree Tender, learning about the Tree of Life, the connections between all organisms on the Tree, the importance of understanding these connections, and the human-caused mass extinction currently occurring. Note: Please read 01 Tree Tender Curriculum Bundle.pdf first. Each of these major concepts are...

View Resource Finding a species-area relationship for island birds using Solver in Excel

Grasping the mathematics underlying the species-area relationship in island biogeography can be difficult for students if they experience it passively. This exercise allows students to take an authentic data set of bird species richness from different islands in the Solomon Islands Archipelago and fit a species-area relationship (S=cAz). Students explore a biological concept in a hands-on...

View Resource Testing hypotheses about behavioral interactions between cats, coyotes, and birds at carcasses

In this activity, students will play the role of a field biologist quantifying and explaining animal behavior using the scientific method (observation – hypothesis – prediction – test). Powerpoint slides contain a series of photos of scavengers at deer carcasses. Students will form hypotheses about the behavioral interactions in the photos, then make predictions that could be used to test their...

View Resource Case Study on Mark and Recapture

Estimating the population size of animals is an important task for wildlife biologists, who can use the data to assess the health of a population. It requires diligent observation skills coupled with the ability to use empirical models that effectively determine the number of animals based on field surveys. The most common method for estimating the population size of animals is mark and recapture....

View Resource Life Cycle Analysis and Assessment of Crop Production Methods

Students use their ecological knowledge of soil processes, energy, water systems, and human interactions to compare the environmental impact of food production. Each group of 3-4 students develop life cycle analyses (LCA) for a single crop grown under different scenarios. As individuals, students are responsible for developing two LCA for that crop, and then together in their groups, they compile...
