===You are nearing the end of the unit about the Puritan tiger beetle, one species threatened with extinction. Its story is just a glimpse into the effort required to maintain biological diversity, or biodiversity of life on Earth. The tasks involve participation by scientists, learners, and teachers. When it comes to exploring the complex relationships between species, you may find yourself in all of these roles at once.===

===Biodiversity is reflected in the variety of ecosystems and species along with their interactions and genetic diversity. It also includes the range of Earth's biomes: savannas, rain forests, deserts, and all the other environments where species are evolving and living. In our region, the Chesapeake Bay is a unique environment, with a heritage of biodiversity. The link below will give you a chance to explore case studies about the challenges facing all species, including humans, that coexist in threatened ecosystems like those along the edge of the bay.===
