There is life all around us! Look out a window, and we see a variety of living things. Even in the middle of a big city, plants grow in between cracks in the sidewalk. All that life is called Biodiversity. Check out the Natural Resources Intern video to learn how high school students are improving biodiversity on an Eastern Oregon ranch. Then, in the Discovery Challenge video, investigate biodiversity at two different sites by collecting data at each sites. With your data, you will be able to compare the biodiversity at the two sites.

This lesson introduces NGSS standards, and those standards are listed in the lesson and is part of the Explore Science Club series, an online Career Connected Learning program developed by the Greater Oregon STEM Hub. To learn more find us at: www.go-stem.org.

Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

By the end of this section, you will be able to:Discuss the predator-prey cycleGive examples of defenses against predation and herbivoryDescribe the competitive exclusion principleGive examples of symbiotic relationships between speciesDescribe community structure and succession

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public.

"Africa contains some of the most species-rich regions in the world. The tropical zone of this continent, for example, harbors the second largest extent of rain forest after the Amazon basin. However, tropical Africa is in the midst of major ecological shifts in response to human pressure and global climate change. Unfortunately, an incomplete understanding of plant diversity in this fragile region may hinder conservation efforts. In an attempt to remedy this, an international team of scientists created the RAINBIO database, a compilation of data gathered from the vast worldwide network of herbaria – or libraries of dried plant specimens. The researchers analyzed over 600,000 specimens for collecting date, geographic occurrence, and growth form (think: trees, herbs, and vines). The results provide an important perspective on plant species richness across the African tropics. For example, Cameroon, Tanzania, and the Democratic Republic of Congo are estimated to be the most species-rich countries..."

This module explores the introduction of the American bullfrog on their ecosystem. Using species diversity calculations and data collection techniques, students explore how the bullfrog affected the species in its community. Students are introduced to calculations like species richness, species evenness, and species diversity indices. Also, this activity provides students an understanding of how this information is gathered in the field and provides them an opportunity to learn how to collect data themselves.

"Islands are hotspots of biodiversity. But they’re in danger. Human activities are disrupting the natural habitats of numerous island plant and animal species, causing them to degrade, fragment, or perish altogether. Including here, in the islands of Japan. In response, the Japanese government has recently committed to a 17% expansion of its network of protected areas, spaces such as national parks that support long-term conservation of biodiversity and natural resources. The proposed expansion is one of the common global strategic plans for biodiversity, specifically, the Aichi Biodiversity Targets. The problem is that experts have no comprehensive, ecologically justified way of determining which areas to include. Now, a team of researchers from Japan and Finland has devised an analytical framework that could make Japan’s protected area expansion as efficient as possible..."
