Biomarkers and bio-indicators

Everyday biomarkers are common biological organisms that express information about an ecosystem or its many parts. In this assignment, you will find and observe an organic system (plant, insect, animal, or a combination of these) to infer something about the environment. Working off ideas from Nurturing Natural Sensors, your goal is to find something living and use it as a sensor.

You can apply any mode of inquiry to identify local biomarkers: online research, interview an expert (e.g., local gardener, beekeeper, etc.), personal experience. Once you pick a bio-indicator or biomarker you must find it in the real world, document it (photograph or video), and explain what it tells you about the environment.

Post your assignment under the “biomarker” category.

This assignment is worth 3 points
1 point for researching an organic system that can be used as a biomarker for region
1 point for finding, observing, and documenting this biomarker in the real world
1 point for explaining what the biomarker you observed tells you about the environment
