The concept of interdependence in an ecosystem and its effect on the evolution of populations is further explored through a model of a dam. Students build a dam in the middle of the field, dividing the ecosystem in half to illustrate the affects of geographic isolation. They watch as the grass and then the rabbit populations in that region shift to one variant in the population. When students remove the dam, they observe the ecosystem slowly return to its original state.

The ecological impacts of climate change are broad and diverse, altering species' range limits, plant phenology and growth, carbon and nutrient cycling, as well as biodiversity and extinction risk. Recent PLOS articles have used a variety of experimental and observational approaches to examine these impacts. The broad range of papers within this Collection emphasize not only the multi-faceted impacts of climate change on ecological and human systems, but also the breadth and depth of research on these subjects being reported in PLOS journals.

In this unit, we describe the theory of evolution by natural selection as proposed by Charles Darwin in his book, first published in 1859, On The Origin of Species by Means of Natural Selection, or The Preservation of Favoured Races in the Struggle for Life. We will look at natural selection as Darwin did, taking inheritance for granted, but ignoring the mechanisms underlying it.

This lesson is an introduction to natural selection and is suited to any student who is just beginning his or her discovery of evolution. The motivation introduces a species of bird that became (over millions of years) numerous species, through adaptation. The development is a hands-on activity that demonstrates how populations change little by little, generation by generation, due to survival of species that have traits that are beneficial in an environment.

In this activity, students learn about how climate change is affecting the Arctic ecosystem and then investigate how this change is impacting polar bear populations. Students analyze maps of Arctic sea ice, temperature graphs, and polar bear population data to answer questions about the impact of climate change on the Arctic ecosystem.

As climate changes, dynamic coastal regions are experiencing a wide range of impacts. Sea levels, ocean acidification, sea surface temperatures, ocean heat, and ocean circulation have all been changing in ways unseen for thousands of years. Arctic sea ice melted significantly more during summers in the last 30 years, and storms are intensifying. Coastal ecosystems stand to be damaged, and coasts will likely erode from rising sea levels, intensified storm surges, and flooding that climate change may amplify. Coastal communities will need to prepare adaptation strategies to cope, and many who live or work in coastal regions are wondering what climate change might mean for them. This module provides an overview of the impacts coastal regions are experiencing and may continue to experience as a result of Earth’s changing climate. A video series within the module demonstrates effective strategies for communicating climate science.

Students will plan and design an imaginary organism that lives in the Temperate Deciduous Forest, Tropical Rainforest, or Desert. Students will then identify three adaptations of this animal, and determine how the adaptations of that animal may respond to a change in the ecosystem.

This "clicker case" begins by assessing students' impressions of global climate change and the role that human activities play in recent global warming trends. Students assume the role of an intern working for a U.S. senator. They need to understand the scientific evidence for human impact on climate change so that they can advise the senator on future policy decisions. The case was designed for use in a one-semester introductory biology course taken primarily by freshmen and sophomores to fulfill a general education requirement, but could be used in any introductory biology course or in an ecology or environmental science course. It consists of a PowerPoint presentation (~1.6MB) presented in class that is punctuated by multiple-choice questions students respond to using personal response systems ("clickers"). The case can be adapted for use without these technologies.

This course presents the principles of evolution, ecology, and behavior for students beginning their study of biology and of the environment. It discusses major ideas and results in a manner accessible to all Yale College undergraduates. Recent advances have energized these fields with results that have implications well beyond their boundaries: ideas, mechanisms, and processes that should form part of the toolkit of all biologists and educated citizens.

In this "clicker case," students learn about natural selection through the research of Peter and Rosemary Grant and colleagues on the finches of the Galapagos Islands. Students are presented with data in the form of graphs and asked to determine what is happening to a population of finches as the changing environment produces changes in the shape of the finches' beaks. This case is suitable for any size course in introductory biology, ecology, or evolution, and does not require any pre-requisite knowledge of evolution or natural selection. The case consists of a PowerPoint presentation (~4.5MB) punctuated by questions that students answer in class using "clickers." It can be adapted for use without these technologies.

In this simulation activity, students experiment with a population of M&M candies or paper dot "beetles" to test how well each color is adapted to survive on a field of colorful wrapping paper or fabric. Students act as predators and see that camouflaged beetles survive predation preferentially. Students reflect on how the activity could be modified to better simulate the process of predation-based natural selection. This activity is supported by a textbook chapter, "Origin of Species," part of the unit, "Losing Biodiversity," in Global Systems Science (GSS), an interdisciplinary course for high school students that emphasizes how scientists from a wide variety of fields work together to understand significant problems of global impact.

This kinesthetic activity simulates the process of evolution by natural selection. Students take on the roles of crab-like predators that exhibit one of four variants of feeding appendage: a spoon, fork, knife, and chopsticks. The simulation runs for three trials, as the predators use their appendages to harvest pinto beans, with varying success. Students track the frequency of each appendage type through three generations. This resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

Principles of natural selection are demonstrated by a simulation that involves different color pom-poms and student feeders equipped with different types of feeding implements. Students analyze results to see how different traits contribute to fitness in different habitats. Additional examples and questions help students to understand the process of natural selection, including three necessary conditions for natural selection to take place.

Earth’s climate has always undergone change. However, modern climate change does not fit the long pattern of geologic history. In the past half century, the rate and extent of climate change has been extraordinary. This change is altering the planet by destroying healthy ecological balances that have been operating for millions of years. The authors of Healing Earth are dedicated to the task of slowing and stopping this destruction. We imagine an Earth restored for future generations. As we have done throughout Healing Earth, we invite you to imagine this with us and join this work.
