The computer program's simulation of a Sonoran desert community should ultimately strengthen the student's comprehension of what is required for a natural ecosystem to sustain itself (remain in balance). This computer simulation program has great flexibility. It allows the student to manipulate the population numbers of five Sonoran Desert species. A species natural history attachment provides vital information for the students to familiarize themselves with each species' behaviors, its niche and food resource needs. The program includes two producers, the Saguaro cactus and the Ironwood Tree. It also includes 3 consumers, but their interactions both toward the producers and each other differ. The community's ability to remain in balance and sustain all five species so that none die out rests on the student's assessment skills enabling him to correctly identify these dependencies. The student learns by trial and error as he continues to fine tune the ecosystem that he maintains stewardship of.

Concepts of Biology is designed for the introductory biology course for nonmajors taught at most two- and four-year colleges. The scope, sequence, and level of the program are designed to match typical course syllabi in the market. Concepts of Biology includes interesting applications, features a rich art program, and conveys the major themes of biology.

In this survey text, directed at those not majoring in biology, we dispel the assumption that a little learning is a dangerous thing. We hope that by skimming the surface of a very deep subject, biology, we may inspire you to drink more deeply and make more informed choices relating to your health, the environment, politics, and the greatest subject that are all of us are entwined in, life itself. This text also includes 80 interactive H5P activities that you can use to evaluate your understanding as you go.

Incorporating elders’ wisdom in the process of systematically analyzing climate impacts and vulnerabilities in nine categories of tribal life prioritizes actions to take to enhance the evolution of an ancient culture, while protecting tribal traditions.

Conservation Biology in Sub-Saharan Africa comprehensively explores the challenges and potential solutions to key conservation issues in Sub-Saharan Africa.

Easy to read, this lucid and accessible textbook includes fifteen chapters that cover a full range of conservation topics, including threats to biodiversity, environmental laws, and protected areas management, as well as related topics such as sustainability, poverty, and human-wildlife conflict. This rich resource also includes a background discussion of what conservation biology is, a wide range of theoretical approaches to the subject, and concrete examples of conservation practice in specific African contexts. Strategies are outlined to protect biodiversity whilst promoting economic development in the region.

This video is from the Khan Academy subject of Partner content on the topic of Crash Course and it covers Conservation and Restoration Ecology.

The video resource "Conservation and Restoration Ecology: Crash Course Ecology #12" is included in the "Ecology" course from the resources series of "Crash Course". Crash Course is a educational video series from John and Hank Green.

Is the food chain shown above accurate? Does the first link depict a producer, the second link a herbivore, and the third link an omnivore / carnivore? Students must correctly determine whether a species is a producer or consumer, and what type of consumer; herbivore, omnivore, or carnivore. Students are provided with a list of Sonoran Desert species and asked to construct, within their groups, several food chains. These food chains are then be used to construct a food web. In order to complete this activity, students must first research the individual species to understand their feeding habits.

Paul Andersen emphasizes the importance of cooperation in living systems. He starts with a brief description of game theory and why countries at peace do better over the long term. He then explains how microscopic cells cooperate in the rumen of a cow, how organelles cooperate in a cell, and how organs cooperate in the digestive system.

Paul Andersen explains the importance role of coupled reactions in biology. He starts by explaining how the power of a river can be harnessed by a water mill to grind grains. He describes the importance of ATP and how it is used within living organisms. He highlights many of the coupled reactions between the Sun and your thumb.

This casebook opens up modes of inquiry into Western knowledge foundations, asking students to embrace epistemological uncertainty as a productive means of developing critical thinking skills.
