BIO 2129 Chapter Notes -Cool Air, Herbivore, Soil Structure
Document Summary
Natural history: study of how organisms are influenced by factors like climate, soils, predators, mutations, evolution history (foundation for modern and conservation ecology) Daniel jazen: wanted to restore the tropical dry forest, wondered why the guanacaste tree produced so much fruit. To promote seed dispersal by animals but there were no animals in sight: natural history led him to discover there was once a whole bunch of herbivorous animals (camels, sloths, horses). Then horses and cattle were introduced by the europeans: tested a hypothesis that horses can act as dispersers for the tree and incorporated this into a management plant, dispersers would accelerate restoration. Uneven heating of earth by the sun and its tilt on the axis combine to produce predictable latitudinal variation in climate. Much climatic variation is caused by uneven heating of its surface by the sun (results from shape and angle)
