Female mice given a choice between territorial marks of exclusive (one odor) and invaded (mixed odor) territories (in the absence of the owner) chose the first odor. Therefore, females use not only the odor of the territory owner but also the absence or presence of marks by competitors (challengers). The absence of any interfering mark identifies the marking male as one of high quality (Hurst and Rich, 1999). In short, individual A can read the story of interactions between individuals B and C and act accordingly to maximize its own fitness. 

Unless we take the right course of action, problems associated with both quality and quantity of water are going to be encountered, even in regions that seem to have sufficient amounts of clean water today. After the disputes and wars over the possession of oil in the past, water may be the next conflict territory between adjacent countries, even in Europe. According to the EC, 20% of all surface water in the European Union is seriously threatened with pollution. Furthermore, water is far from being evenly distributed in Europe and this is one major reason for resource problems. For example, whereas freshwater availability is more than 100,000 m3 per capita per year in Iceland, it is less than 10,000 m3 per capita per year in Switzerland, Portugal, and Spain.

Leaves of many species also give off volatile oils which can be directly adsorbed by soil or be carried down in rain, von Rudloff (10), for example, reported that the quality and quantity of oils in needles of white spruce (Picea gauca) were relatively constant over a large range of territory. We will return to some of those 18 compounds or groups later ...
