At this stage, air circulation enters and plays a dual role. Firstly, winds transmit moisture horizontally from one location to another. In this way, moisture derived from oceanic evaporation can be transported many miles to a land mass. Secondly, convective or vertical currents arising from unequal heating or cooling can transmit moisture upwards. When it cools, some of the water vapour condenses. It is from these currents that most precipitation develops.

1.6 Conclusion

This course has presented an overview of the ways in which organisms living in temperate habitats are adapted to survive the winter. The course has shown how a limited set of environmental changes associated with the onset of winter can lead to a diversity of adaptations and therefore a large diversity of species.

On the basis of the examples discussed in this course, we can identify four factors that contribute to the diversity of adaptive strategies for coping with winter.

1.1 Introduction to vitamins and why we need them

Before the 19th century, one of the hazards of long sea voyages was a condition called scurvy, whose symptoms were loss of hair and teeth, bleeding gums, very slow healing of wounds, and eventually death. Hundreds of sailors and explorers died from scurvy until a Scottish physician, James Lind, in the 1750s discovered that adding a daily portion of citrus fruit to the rations of those at sea could prevent the condition, whereas adding cider, vinegar or various other substances that he tested,

1.1 The biological effects of ethanol

This section investigates some of the harmful effects that a high level of blood-ethanol can have on the body: both short-term problems such as â€˜hangoverâ€™, and long-term health problems that are associated with regular heavy drinking. Whilst this section is primarily about the biological effects that ethanol has on various organs of the body, it is important to remember that the socioeconomic effects of heavy drinking are also very serious (Paton, 2005).
