Document Summary
Natural history is the study of how organisms in a area are influenced by climate, soils, predators, competitors and evolutionary history. A good understanding of natural history provides the foundation for modern ecology and conservation biology. Figure 2. 1- a guanacaste tree in costa rica provides large amounts of edible fruit which requires large herbivores to disperse their seeds. This phenomenon of the guanacaste tree producing so much fruit was tackled by daniel janzen, who wanted to restore tropical dry forest to. A common theme throughout the book is that people are not separate from ecological processes. Life on land is very brutal as terrestrial organisms are essentially bags of water surrounded by dry air and are affected by the cold and heat. Another stressor is gravity as terrestrial organisms due not have the natural buoyancy that aquatic organism do have. Dealing with these stressors requires many specific traits, like sweating.
