Cooperative Interactions

049 - Cooperative Interactions 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. Do you speak another language?

Populations

050 - Populations Paul Andersen explains how populations interact in an ecosystem. The symbiosis of several populations is based on effects that may be neutral, positive, or negative. Interactions like mutualism, commensalism and parasitism are included. Human impacts to ecosystems are also considered using the invasive species kudzu. Do you speak another language?

Ecosystem Change

051 - Ecosystems Change Paul Andersen explains how ecosystems change over time. He starts by explaining how global climate change will impacts ecosystems around the planet. He then discusses how continental drift created climatic changes that impacted mammal species. He finishes with a brief discussion of how local meteorological changes can impact local ecosystems.

Cellular Variation

052 - Cellular Variation Paul Andersen explains how variation is created within a cell. He starts by showing how molecular variation can increase fitness at the local level. He explains how an additional chlorophyll molecule allows plants to absorb more light from the sun. He also explains how cells can vary the composition of phospholipids in their cell membrane. He explains the significance of heterozygote advantage and how gene duplication can create novel genes. The antifreeze ...

Genotype Expression

053 - Environmental Genotype Effects Paul Andersen explains how genotypes can be expressed or not based on changes in the environment. He starts with a brief description of the Himalayan rabbit and how melanin production can be disrupted by high temperature. He explains how this could be advantageous in both the arctic fox and hare. He explains how flowers can vary temperature based on the pH of the soil. He finally describes gene expression in Lac+ ...

Population Variation

054 - Population Variation Paul Andersen explains the importance of genetic variation within a population. He begins with a discussion of the devil facial tumor that is a form of cancer transferred between Tasmanian devils. He then explains how a decrease in genetic variability nearly led to the extinction of the black-footed ferret. He finally discussed the importance of genetic variability in disease resistance. He explains how mutations in humans allow some of them to be ...

Biodiversity

055 - Biodiversity Paul Andersen explains the importance of biodiversity. He starts by describing how biodiversity can be species, genetic or ecosystem diversity. He explains the importance of keystone species in an environment and gives two examples; the jaguar and the sea otter. He finishes with a quote from the father of biodiversity, E.O. Wilson.
