Hibernation is an ingenious adaptation that some animals employ to survive difficult conditions in winter. This unit examines the differences between hibernation and torpor, and discusses the characteristic signs of hibernation behavior It explores the triggers that bring on hibernation, and whether internal signals or external season cues are predominant. It also examines the physiological adaptations that occur in hibernating animals. (less)

Animals at the Extremes: Polar Biology

Animals at the Extremes: Polar Biology

The extreme challenges of life in the polar regions require the animals who make their habitat there to make many adaptations. This unit explores the polar climate and how animals like reindeer, polar bears, penguins, sea life and even humans manage to survive there. It looks at the adaptations to physiological proceses, the environmental effects on diet, activity and fecundity, and contrasts the strategies of aquatic and land-based animals in surviving in this extreme habitat. This unit builds on and develops ideas from two other 'Animals at the extreme' units: The desert environment (S324_1) and Hibernation and torpor (S324_2). (less)

Animal life has adapted to survive in the most unlikely and inhospitable habitats. This unit looks at the surprisingly diverse desert climates throughout the world and mammals, birds, lizards and amphibians that survive there. It splits these animals into three groups according to their strategy for survival: evaders, evaporators and endurers, then discusses how these strategies work on a biochemical and physiological level.

This is a basic animation/simulation with background information about the greenhouse effect by DAMOCLES. The animation has several layers to it that allow users to drill into more detail about the natural greenhouse effect and different aspects of it, including volcanic aerosols and human impacts from burning fossil fuels.

In 1978, scientists predicted that global warming would lead to a disintegration of Antarctic Peninsula ice shelves. Space-borne data indicate that this prediction may be coming true. In these before and after images, note the dramatic change in the apparent shoreline. Scientists captured the first image using the ERS-1 satellite in 1992. As seen in the second image, collected by RADARSAT in 1997, huge changes have come to the coastline. In 1995, a 2000 square kilometer section of the ice shelf collapsed into thousands of fragments that eventually drifted out to sea. Researchers are still debating why the ice shelf broke up so dramatically, and what significance the break up has for interpreting local versus global changes to the environment. Theories include a series of warmer than usual summers which may have caused high levels of surface melting, or an overall climate warming trend. (less)
