Peter Franks shares the astonishing findings from cutting-edge equipment he and colleagues have developed to chart the distribution of Phytoplankton, the tiny single-celled plants of the sea that are the base of the marine food chain. (55 minutes)

Join Scripps director Charles Kennel, a member of the Pew Oceans Commission, as he discusses the crisis in marine ecosystems and the scientific and governance challenges inherent in responding to the crisis. (53 minutes)

Join Scripps' Bill Gerwick in an exploration of the potential uses of one of the most ancient of all life forms - blue-green algae - as a source for new pharmaceuticals with used ranging from anticancer compounds to drug screening. (54 minutes)

Charles Kennel explores how the convergence of earth science, biology, and social science through the use of information technology can lead to continuous awareness of Earth's systems, enabling coordinated responses to the global environmental challenges that face us now and in the future. (58 minutes)

One of the greatest challenges facing society today is protecting and restoring biodiversity in the oceans. Join Dr. Nancy Knowlton, director of ScrippsŐs Center for Marine Biodiversity and Conservation as she describes how CMBC research activities are helping us rise to this challenge. (59 minutes)

Little is known of the initial phase of the sea turtle's lifecycle,especially the critically endangered leatherback. Ocean surface currents play an important role as "conveyer belts" for hatchlings, but these strong swimmers might still be able to influence their trajectories at sea. Join Scripps marine biology student Geoffrey Gearheart as he explains how scientists are determining the dispersal patterns and mechanisms of leatherback hatchlings of west Papua (Indonesia) and how this knowledge may help tailor more adequate conservation measures. (56 minutes)

For time immemorial, humanity has looked at the world's oceans as a vast unending sea of resources, but imagine a Serengeti where the elephants and the lions are gone and the top consumers are termites and locusts. That is what is happening in the ocean. Join Dr. Jeremy Jackson as he considers the biological future of the oceans in the context of accelerated human disturbance. (28 minutes)

While often treated as distinct and independent ecosystems, marine and terrestrial habitats are intimately connected through a number of pathways, both natural and unnatural. Join University of San Diego biological oceanographer and Scripps graduate Drew Talley, as he discusses the ways in which these linkages are formed (and broken), and how connectivity across academic, public, and government sectors can help us to better understand coastal habitats. (55 minutes)

At first glance, the owl limpet appears to be an innocuous, slow moving snail on the rocky intertidal shores. Delve further into its behavior and youŐll discover a sex-changing, fighting gastropod. Join Birch Aquarium visiting scientist Stephanie Schroeder as she leads you through the fascinating world of limpet interactions and explains her research examining territorial snail behavior. (50 minutes)

Join Dr. Kathy Barbeau and explore the world of Phytoplankton, from the molecular to the global scale, in her quest to understand the mysterious role of iron in Phytoplankton ecology. (55 minutes)

Join Scripps physical oceanographer Clint Winant as he describes this complex interface between the land and sea. Learn how he and his colleagues are providing insight into how human activities can impair this fragile ecosystem. (54 minutes)

In this module, students will practice answering a specific question about how climate change has affected the flowering date in American elm trees. After students learn to manipulate the elm data set, build graphs, and analyze the data with a regression, they can then practice on a species of their own interest. Students can then share their species' information with the class for a larger discussion about what types of species may be affected by climate change.

This illustration shows both the linear and cyclic flow of electrons during the light reaction of photosynthesis.

Classic writing on the social psychology of money by the youthful Karl Marx.

A Primer of Evolution is an open educational resource designed for upper-level college students. It provides a succinct introduction to evolutionary thought revolving around theory, evidence, and practice:
- It introduces some of the theoretical cornerstones and core concepts of modern evolutionary biology. The goal is for students to be able to apply these concepts and articulate testable hypotheses that explain natural phenomena from an evolutionary perspective.
- It highlights the diversity of empirical approaches and lines of evidence that scientists use to address evolutionary hypotheses.
- It helps students to practice approaching problems like scientists and evaluate data to address evolutionary hypotheses. To do so, students learn how to program in R to analyze and visualize data and articulate your interpretations and conclusions.

Each chapter provides a conceptual introduction to the topic and includes R-based exercises that allow students to visualize relevant datasets to practice the testing of evolutionary hypotheses. To help with the R exercises, each chapter also provides additional background on case studies and R programming tutorials that help students to develop the necessary skills.

Quantitative Ecology introduces and discusses the principles of ecology from populations to ecosystems including human populations, disease, exotic organisms, habitat fragmentation, biodiversity and global dynamics. The book also reformulates and unifies ecological equations making them more accessible to the reader and easier to teach.

We use eigenvector-eigenvalue analysis to walk through a simple quasispecies model described in Bull, Meyers, and Lachmann, "Quasispecies made simple," PLoS Comp Biol, 1(6):e61 (2005). The dominance of a genotype depends, not merely on its ability to breed quickly (i.e. the rudimentary concept of survival of the fittest), but also on its ability to breed "true."
