The ocean provides a bounty of essential life-supporting services. Yet, a changing climate and increasing human uses are altering marine ecosystems and their ability to continue to provide this wealth of essential services. Off the coast of California, we are lucky to have one of the worlds longest-running marine observation programs, the California Cooperative Oceanic Fisheries Investigations (CalCOFI), which has continuously and comprehensively sampled the marine environment off the California coast since 1949 to monitor the indicators and impacts of El Nino and climate change and to support effective marine management. Join marine ecologist and California Sea Grant extension specialist Erin Satterthwaite as she tells the story of CalCOFI through a series of case studies documenting how CalCOFI has been used to understand and address human and natural impacts on marine life along the California coast.

Discussion session about The Evolution of Human Physical Activity. Series: "CARTA - Center for Academic Research and Training in Anthropogeny" [Science] [Show ID: 37188]

Human physical activities differ significantly from other species. How, when and why did these capabilities evolve? What adaptations underlie them? And how did the evolution of human physical activity affect other key human characteristics that have advanced our species? Herman Pontzer explores the evolution of metabolism, Grazyna Jasienska discusses different effects of activity on women's reproductive health and Ellen Breen explores an evolutionary pathway for high endurance activity.

A growing body of evidence suggests that the evolutionary roots of much of the aggression, intolerance, and violence that plagues modern societies ultimately lies in the selection that shaped our mating system. Acknowledging and understanding the legacy of male interpersonal and group aggression can help guide policy directed at reducing violence in the future.

Human physical activities differ significantly from other species. How, when and why did these capabilities evolve? What adaptations underlie them? And how did the evolution of human physical activity affect other key human characteristics that have advanced our species? Jandy Hanna explores climbing in human evolution.

Most primates live and move in the trees, but humans have evolved to move bipedally on the ground. Primates’ arboreal life-style has long been thought to have allowed the evolution of human beings’ unusual form of movement. We know much about how horizontal movement on branches differs in primates relative to most other mammals. But only recently have we begun to learn about how climbing is accomplished by non-human primates, and how such movement may have permitted early human ancestors to move upright. Key findings regarding the biomechanics of climbing, and what these data may mean for understanding human movement and exercise, are discussed.

Human physical activities differ significantly from other species. How, when and why did these capabilities evolve? What adaptations underlie them? And how did the evolution of human physical activity affect other key human characteristics that have advanced our species? Grazyna Jasienska discusses different effects of activity on women's reproductive health. The effects of physical activity on female physiology and health are much more complex than for men. Just like in men, activity is beneficial for many aspects of health, but physically active women also face important physiological trade-offs. Physical activity influences levels of hormones that are crucial for female health – estrogens and progesterone. But how much and in what way these hormones are affected depends not only on the type and intensity of physical activity, but also on other factors, such as the quality of environment that women experienced during their own fetal development and childhood.
