Hank explains speciation - the evolutionary process by which new biological species arise - in terms of finches, ligers, mules, and dogs.

The video resource "Speciation: Of Ligers & Men - Crash Course Biology #15" is included in the "Biology" course from the resources series of "Crash Course". Crash Course is a educational video series from John and Hank Green.

Paul Andersen details the evolutionary processes of speciation and extinction. Stickleback evolution in Lake Loberg is used as example of rapid speciation. Adaptive radiation is illustrated using the Hawaiian honeycreeper. A brief discussion of extinctions and mass extinctions is also included.

The Stabilization Wedges game is a simple framework for understanding both the carbon emissions cuts needed to avoid dramatic climate change and the tools already available to do so. The resource, "Stabilization Wedges: A Concept and Game" included in "Lesson 1 Climate Change Negotiations" is a part of "Unit 10 Mock Summit and Portfolio Capstone Finale" included in Energy & Sustainability ES - Course 4.

Paul Andersen describes microevolution and macroevolution in the stickleback fish of Loberg Lake. He describes how anadramous fish repopulated the lake after poisoning and adapted to the new environment through natural selection. He also explains how reproductive isolation has appeared in fish that have diverged only a few decades in the past.

This course will provide you with skills to overcome barriers to action, mobilize knowledge and data effectively, and work across silos in genuine interdisciplinary and collaborative practice. You’ll learn how to lead or participate in community engagement, without triggering fear and overwhelming others; practise critical self-awareness and self-reflection; and consider equity-based and decolonizing approaches.



This course is designed for professionals looking to advance the intersecting work of climate action and adaptation, including planners, engineers, elected officials and community leaders. You will leave with practical and relevant skills to lead, accelerate and participate in the essential work of climate adaptation in your organization and community.



LEARNING OUTCOMES

By the end of the course, you will be able to do the following:



• Describe the dynamics of collaborative, team-based planning processes

• Apply key concepts in climate communications and knowledge mobilization

• Engage in meaningful dialogue with internal and external stakeholders

• Develop adaptive and responsive strategies for working in complex systems

• Analyze and overcome internal and external barriers to climate adaptation

Strawberry DNA Extraction is a fun experiment that you can perform using everyday materials. The purpose of this experiment is to develop the interest, knowledge and skills of our students in the areas of biotechnology and life sciences. It engages students with a hands-on activity that is fun, interesting and informative and that can be used with a variety of levels from grade school to high school by tailoring the complexity of accompanying material.

In this activity, students will use several web tools to analyze CO2 concentrations from sites around the globe, measured by NOAA. By analyzing short and long-term trends of CO2 in the atmosphere, students will learn how the atmosphere and climate are changing and determine the causes that are responsible for these changes.

A Student’s Guide to Tropical Marine Biology is written entirely by students enrolled in the Keene State College Tropical Marine Biology course taught by Dr. Karen Cangialosi. Our goal was to investigate three main aspects of tropical marine biology: understanding the system, identifying problems, and evaluating solutions. Each of the sections contains chapters that utilize openly licensed material and images, and are rich with hyperlinks to other sources. Some of the most pressing tropical marine ecosystem issues are broken up into five sections: Coral Reefs and Diversity, Common Fishes to the Coral Reef, Environmental Threats, Reef Conservation, and Major Marine Phyla. These sections are not mutually exclusive; repetition in some content between chapters is intentional as we expect that users may not read the whole book. This work represents a unique collaborative process with many students across semesters authoring and editing, and therefore reflects the interests and intentions of a broad range of students, not one person’s ideas. This collaboration began with contributions from KSC students in the 2017 semester and includes work from the 2019 class, as well as new content and editorial work from 2017 & 2019 alumni. We look forward to future editions of this book. Enjoy exploring the rainforests of the sea through our collaborative project and please share with those who care!

Students observe natural selection in action and investigate the underlying mechanism, including random mutation and differential fitness based on environmental characteristics. They do this through use of the free AVIDA-ED digital evolution software application.

This course will introduce you to a general overview of the biological world. Important concepts will be reinforced and expanded upon through completion of weekly laboratory activities and homework assignments. Upon successful conclusion of the course, students will be able to do the following: Describe the nature of science, including its methods and its limitations; Describe the basic methodology of doing science and the scientific method; Use the scientific method to study everyday situations as well as in laboratory/field investigations; Identify, describe, and explain at a rudimentary level and present examples of, the characteristics common to all living things; Explain that living organisms are composed of molecules which interact in a variety of different chemical reactions necessary to sustain life; Explain that living organisms are comprised of one or more cells and are classified as prokaryotic or eukaryotic based on cellular characteristics; Describe the hereditary information possessed by living and explain how that information determines the cellular characteristics and functions (including basic Mendelian genetics); Explain and describe, with examples, the diversity of life, at different levels (basic molecular to ecological) and how it is hierarchically organized into systems; Explain how evolution by natural selection occurs, and describe the evidence that supports the theory of evolution; and more.

Students engineer and evolve digital organisms with the challenge to produce organisms with the highest fitness values in a particular environment. They do this through use of the free Avida-ED digital evolution software application. The resulting organisms compete against each other in the same environment and students learn the benefits of applying the principles of natural selection to solve engineering design problems.
