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.

We welcome contributions to our growing number of resources for middle and high school audiences that align with the Next Generation Science Standards.

You will be able to share images, syllabi, labs, lectures, figures, videos, classroom activities and data sets in LifeDiscoveryEdDL. We're here to assist you to submit your resource.

To submit a resource. You will need to select one of the three participating portals to initiate the review process:

View Resource Measuring Soil Microbial Activity

This activity examines how soil microbes, such as bacteria and fungi, are involved in carbon cycling. Students design experiments to explore the relationship between microbial respiration rates and soil variables such as temperature, habitat, soil type, and agricultural management choices. Four methods for measuring CO2 released from soil are provided, one in the field (CO2 probe), and three in...

View Resource False eye-spots on an owl

These photos of a Pearl-spotted Owlet (Glaucidium perlatum) were taken in Kruger National Park in 2015. From the front, this diminutive owl looks like any other. From the back, it has false eye-spots (presumably to startle predators).

View Resource How the Bioblitz Boosts the Zoology Course

Collection of invertebrates on campus, as part of the BioBlitz, increases the interest in students in animals as they get to go out to the field and collect specimens. They also learn about collection techniques and equipment. These activities also provide an opportunity for experimental design. Students are also contributing to the species count of the BioBlitz.

View Resource Literature circles as active learning packets for use in the natural sciences: Transforming traditional supplemental instruction into guided study

At Paul Smith's College, we have worked to transform the model of weekly SI (supplemental instruction) into GSG (Guided Study) for General Ecology (Bio 210). We modified literature circle worksheets based off of the work of Harvey Daniels to be used in the natural sciences. We then created a step-by-step instructional framework to implement literature circles in the natural sciences. This...

View Resource Egg size plasticity in bean beetles (Callosobruchus maculatus): Does host bean species matter?

In this exercise, students design a series of experiments (1) to test whether female bean beetles adjust the size of their eggs on different host bean species and (2) to determine whether differences in egg size based on host bean species are optimal. Most often, students design experiments in which different females are allowed to lay eggs on different bean species that vary in nutritional...
